Install Tomcat 7 on CentOS, RHEL, or Fedora

This post will cover installing and basic configuration of Tomcat 7 on CentOS 5.x. or CentOS 6.x

Tomcat 7 implements the JavaServer Pages 2.2 and Servlet 3.0 specifications and a number of new features. The Manager application also has a new look and finer-grain roles and access than 6.x

In this post, we'll install Tomcat 7, the new JDK 7, configure Tomcat as a service, create a start/stop script, and (optionally) configure Tomcat to run under a non-root user.

We will also configure basic access to Tomcat Manager and take a quick look at memory management using JAVA_OPTS

Finally, we will look at running Tomcat on port 80 as well as some strategies for running Tomcat behind Apache.

I have just updated this post with Tomcat 7.0.29, the current stable release of Tomcat 7.

If you are using a different release, simply change the file names below accordingly.

To begin, we'll need to install the Java Development Kit (JDK) 7

JDK 1.6 is the minimum JDK version for Tomcat 7.


Step 1: Install JDK 1.7



You can download the latest JDK here: http://www.oracle.com/technetwork/java/javase/downloads/index.html

We'll install the latest JDK, which is JDK 7, Update 5. The JDK is specific to 32 and 64 bit versions.

My CentOS box is 64 bit, so I'll need: jdk-7u5-linux-x64.tar.gz.

If you are on 32 bit, you'll need: jdk-7u5-linux-i586.tar.gz

Start by creating a new directory /usr/java:

[root@srv6 ~]# mkdir /usr/java  


Change to the /usr/java directory we created

[root@srv6 ~]# cd /usr/java  
[root@srv6 java ]# 


Download the appropriate JDK and save it to /usr/java directory we created above.

Unpack jdk-7u5-linux-x64.tar.gz in the /usr/java directory using tar -xzf:

[root@srv6 java]# tar -xzf jdk-7u5-linux-x64.tar.gz


This will create the directory /usr/java/jdk1.7.0_05. This will be our JAVA_HOME.


We can now set JAVA_HOME and put Java into the path of our users.

To set it for your current session, you can issue the following from the CLI:
[root@srv6 java]# JAVA_HOME=/usr/java/jdk1.7.0_05
[root@srv6 java]# export JAVA_HOME
[root@srv6 java]# PATH=$JAVA_HOME/bin:$PATH
[root@srv6 java]# export PATH

To set the JAVA_HOME permanently, however, we need to add below to the ~/.bash_profile of the user (in this case, root).
We can also add it /etc/profile and then source it to give to all users.
JAVA_HOME=/usr/java/jdk1.7.0_05
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
Once you have added the above to ~/.bash_profile, you should log out, then log back in and check that the JAVA_HOME is set correctly.

[root@srv6 ~]#  echo $JAVA_HOME
/usr/java/jdk1.7.0_05


Note: If you decided to use JDK 6 rather than 7 as we did above, simply save the JDK 6 bin file to /opt (or another location), then navigate to /usr/java and issue: 'sh /opt/jdk-6u33-linux-x64.bin'. This will create a JAVA Home of /usr/java/jdk1.6.0.33


Step 2: Download and Unpack Tomcat 7.0.29 (or latest)



We will install Tomcat 7 under /usr/share.

Switch to the /usr/share directory:

[root@srv6 ~]# cd /usr/share
[root@srv6 share ]# 
Download apache-tomcat-7.0.29.tar.gz (or the latest version) here

and save it to /usr/share

Once downloaded, you should verify the MD5 Checksum for your Tomcat download using the md5sum command.

[root@srv6 share ]# md5sum apache-tomcat-7.0.29.tar.gz
307076fa3827e19fa9b03f3ef7cf1f3f *apache-tomcat-7.0.29.tar.gz
Compare the output above to the MD5 Checksum provided next to the download link and you used above and check that it matches.

unpack the file using tar -xzf:

[root@srv6 share ]# tar -xzf apache-tomcat-7.0.29.tar.gz  
This will create the directory /usr/share/apache-tomcat-7.0.29


Step 3: Configure Tomcat to Run as a Service.



We will now see how to run Tomcat as a service and create a simple Start/Stop/Restart script, as well as to start Tomcat at boot.

Change to the /etc/init.d directory and create a script called 'tomcat' as shown below.

[root@srv6 share]# cd /etc/init.d
[root@srv6 init.d]# vi tomcat
And here is the script we will use.

#!/bin/bash
# description: Tomcat Start Stop Restart
# processname: tomcat
# chkconfig: 234 20 80
JAVA_HOME=/usr/java/jdk1.7.0_05
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
CATALINA_HOME=/usr/share/apache-tomcat-7.0.29

case $1 in
start)
sh $CATALINA_HOME/bin/startup.sh
;; 
stop)   
sh $CATALINA_HOME/bin/shutdown.sh
;; 
restart)
sh $CATALINA_HOME/bin/shutdown.sh
sh $CATALINA_HOME/bin/startup.sh
;; 
esac    
exit 0
The above script is simple and contains all of the basic elements you will need to get going.

As you can see, we are simply calling the startup.sh and shutdown.sh scripts located in the Tomcat bin directory (/usr/share/apache-tomcat-7.0.29/bin).

You can adjust your script according to your needs and, in subsequent posts, we'll look at additional examples.

CATALINA_HOME is the Tomcat home directory (/usr/share/apache-tomcat-7.0.29)

Now, set the permissions for your script to make it executable:

[root@srv6 init.d]# chmod 755 tomcat
We now use the chkconfig utility to have Tomcat start at boot time. In my script above, I am using chkconfig: 234 20 80. 2345 are the run levels and 20 and 80 are the stop and start priorities respectively. You can adjust as needed.

[root@srv6 init.d]# chkconfig --add tomcat
[root@srv6 init.d]# chkconfig --level 234 tomcat on
Verify it:

[root@srv6 init.d]# chkconfig --list tomcat
tomcat          0:off   1:off   2:on    3:on    4:on    5:off   6:off
Now, let's test our script.

Start Tomcat:
[root@srv6 ~]# service tomcat start
Using CATALINA_BASE:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_HOME:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/share/apache-tomcat-7.0.29/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_05
Using CLASSPATH:       /usr/share/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/share/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Stop Tomcat:

[root@srv6 ~]# service tomcat stop
Using CATALINA_BASE:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_HOME:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/share/apache-tomcat-7.0.29/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_05
Using CLASSPATH:       /usr/share/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/share/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Restarting Tomcat (Must be started first):

[root@srv6 ~]# service tomcat restart
Using CATALINA_BASE:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_HOME:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/share/apache-tomcat-7.0.29/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_05
Using CLASSPATH:       /usr/share/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/share/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Using CATALINA_BASE:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_HOME:   /usr/share/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/share/apache-tomcat-7.0.29/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_05
Using CLASSPATH:       /usr/share/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/share/apache-tomcat-7.0.29/bin/tomcat-juli.jar
We should review the Catalina.out log located at /usr/share/apache-tomcat-7.0.29/logs/catalina.out and check for any errors.

[root@srv6 init.d]# more /usr/share/apache-tomcat-7.0.29/logs/catalina.out
We can now access the Tomcat Manager page at:

http://yourdomain.com:8080 or http://yourIPaddress:8080 and we should see the Tomcat home page.


Step 4: Configuring Tomcat Manager Access.



Tomcat 7 contains a number of changes that offer finer-grain roles.

For security reasons, no users or passwords are created for the Tomcat manager roles by default. In a production deployment, it is always best to remove the Manager application.

To set roles, user name(s) and password(s), we need to configure the tomcat-users.xml file located at $CATALINA_HOME/conf/tomcat-users.xml.

In the case of our installation, $CATALINA_HOME is located at /usr/share/apache-tomcat-7.0.29.

By default the Tomcat 7 tomcat-users.xml file will have the elements between the and tags commented-out. .

New roles for Tomcat 7 offer finer-grained access and The following roles are now available:

manager-gui
manager-status
manager-jmx
manager-script
admin-gu
admin-script.

We can set the manager-gui role, for example as below

:
<tomcat-users>
<role rolename="manager-gui"/>
<user username="tomcat" password="secret" roles="manager-gui"/>
</tomcat-users>


Caution should be exercised in granting multiple roles so as not to under-mind security.


Step 5 (Oprtional): Manage Memory Usage Using JAVA_OPTS.



Getting the right heap memory settings for your installation will depend on a number of factors.

For simplicity, we will set our inital heap size, Xms, and our maximum heap size, Xmx, to the same value of 128 Mb

Simliarly, there are several approaches you can take as to where and how you set your JAVA_OPTS

Again, for simplicity, we will add our JAVA_OPTS memory parameters in our Catalina.sh file.

So, open the Catalina.sh file located under /usr/share/apache-tomcat-7.0.29/bin with a text editor or vi.

Since we are using 128 Mb for both initial and maximum heap size, add the following line to Catalina.sh

JAVA_OPTS="-Xms128m -Xmx128m" 


I usually just add this in the second line of the file so it looks as so:

#!/bin/sh
JAVA_OPTS="-Xms128m -Xmx128m"

Step 6 (Optional): How to Run Tomcat using Minimally Privileged (non-root) User.



In our Tomcat configuration above, we are running Tomcat as Root.

For security reasons, it is always best to run services with the only those privileges that are necessary.

There are some who make a strong case that this is not required, but it's always best to err on the side of caution.

To run Tomcat as non-root user, we need to do the following:

1. Create the group 'tomcat':

[root@srv6 ~]# groupadd tomcat
2. Create the user 'tomcat' and add this user to the tomcat group we created above.

[root@srv6 ~]# useradd -s /bin/bash -g tomcat tomcat
The above will create a home directory for the user tomcat in the default user home as /home/tomcat

If we want the home directory to be elsewhere, we simply specify so using the -d switch.

[root@srv6 ~]# useradd -g tomcat -d /usr/share/apache-tomcat-7.0.29/tomcat tomcat
The above will create the user tomcat's home directory as /usr/share/apache-tomcat-7.0.29/tomcat

3. Change ownership of the tomcat files to the user tomcat we created above:

[root@srv6 ~]# chown -Rf tomcat.tomcat /usr/share/apache-tomcat-7.0.29/
Note: it is possible to enhance our security still further by making certain files and directories read-only. This will not be covered in this post and care should be used when setting such permissions.

4. Adjust the start/stop service script we created above. In our new script, we need to su to the user tomcat:

#!/bin/bash
# description: Tomcat Start Stop Restart
# processname: tomcat
# chkconfig: 234 20 80
JAVA_HOME=/usr/java/jdk1.7.0_05
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
CATALINA_HOME=/usr/share/apache-tomcat-7.0.29/bin

case $1 in
start)
/bin/su tomcat $CATALINA_HOME/startup.sh
;; 
stop)   
/bin/su tomcat $CATALINA_HOME/shutdown.sh
;; 
restart)
/bin/su tomcat $CATALINA_HOME/shutdown.sh
/bin/su tomcat $CATALINA_HOME/startup.sh
;; 
esac    
exit 0



Step 7 (Optional): How to Run Tomcat on Port 80 as Non-Root User.



Note: the following applies when you are running Tomcat in "stand alone" mode with Tomcat running under the minimally privileged user Tomcat we created in the previous step.

To run services below port 1024 as a user other than root, you can add the following to your IP tables:

[root@srv6 ~]# iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8080  
[root@srv6 ~]# iptables -t nat -A PREROUTING -p udp -m udp --dport 80 -j REDIRECT --to-ports 8080  


Be sure to save and restart your IP Tables.

Step 8 (Optional): Running Tomcat behind Apache



As an alternative to running Tomcat on port 80, if you have Apache in front of Tomcat, you can use mod_proxy as well as ajp connector to map your domain to your Tomcat application(s) using an Apache vhost as shown below.

While Tomcat has improved it's 'standalone performance', I still prefer to have Apace in front of it for a number of reasons.

In your Apache config, be sure to set KeepAlive to 'on'. Apache tuning, of course, is a whole subject in itself...


Example 1: VHOST with mod_proxy:





<VirtualHost *:80>
    ServerAdmin admin@yourdomain.com
    ServerName yourdomain.com
    ServerAlias www.yourdomain.com


    ProxyRequests Off
    ProxyPreserveHost On
    <Proxy *>
       Order allow,deny
       Allow from all
    </Proxy>


    ProxyPass / http://localhost:8080/
    ProxyPassReverse / http://localhost:8080/


    ErrorLog logs/yourdomain.com-error_log
    CustomLog logs/yourdomain.com-access_log common

</VirtualHost>


Example 2: VHOST with ajp connector and mod_proxy:

<VirtualHost *:80>
	ServerAdmin admin@yourdomain.com
	ServerName yourdomain.com
	ServerAlias www.yourdomain.com


	ProxyRequests Off
	ProxyPreserveHost On
	<Proxy *>
	Order allow,deny
	Allow from all
	</Proxy>

	ProxyPass / ajp://localhost:8009/
	ProxyPassReverse / ajp://localhost:8009/


	ErrorLog logs/yourdomain.com-error_log
	CustomLog logs/yourdomain.com-access_log common
</VirtualHost>



In both vhost examples above, we are "mapping" the domain to Tomcat's ROOT directory.

If we wish to map to an application such as yourdomain.com/myapp, we can add some rewrite as shown below.

This will rewrite all requests for yourdomain.com to yourdomain.com/myapp.

Example 3: VHOST with rewrite:


<VirtualHost *:80>
	ServerAdmin admin@yourdomain.com
	ServerName yourdomain.com
	ServerAlias www.yourdomain.com


	RewriteEngine On
	RewriteRule ^/$ myapp/ [R=301]

	ProxyRequests Off
	ProxyPreserveHost On
	<Proxy *>
	Order allow,deny
	Allow from all
	</Proxy>

	ProxyPass / ajp://localhost:8009/
	ProxyPassReverse / ajp://localhost:8009/


	ErrorLog logs/yourdomain.com-error_log
	CustomLog logs/yourdomain.com-access_log common
</VirtualHost>

+1 to that, really helpful. I've installed solr with tomcat a dozen times or more on Windows but faced with a bare-bones RedHat server and zero linux experience was a bit befuddled. Happily your instructions contain enough detail to get me through even the n00b linux hurdles of making users and groups, chown etc. So big thanks!

Awesome piece. Straight to the point and on-point. Good one David.

Thanks a lot David, I followed your guide and everything looks fine.

One question, in the second tomcat init script you changed CATALINA_HOME fro TOMCAT_HOME

. Why was that?, or is irrelevant how it is called?

Posted by Andres Arenas on November 18, 2011 at 09:34 AM CST #

this part not work

i canĀ“t understand

This will create the directory /usr/java/jdk1.7.0

[root@srv6 ~]# cd /usr/java
[root@srv6 java]# sh /opt/jdk-7-linux-x64.tar.gz

Posted by Francisco on December 04, 2011 at 07:16 PM CST #

Hi Francisco -

Please look again at Step 1.

You need to first unpack the file:

[root@srv6 java]# tar -xzf jdk-7u1-linux-x64.tar.gz

David

Posted by David Ghedini on December 05, 2011 at 03:17 AM CST #

Hi Andres -

Thanks for pointing this out. I have updated both to CATALINA_HOME for consistency.

It does not matter what you call this in the script I included as it is only being used only as shorthand for the path /usr/share/apache-tomcat-7.0.21

You could call it ANDRES_HOME and it would work the same.

Thanks,
David

Dear David

I am learning JEE and Ubuntu.

I have installed oracle java successfully (1.7). Downloaded apache-tomcat 7.0.23 .

when i test : service tomcat start i get the following output:

root@anoop-Inspiron-N5010:/usr/share/apache-tomcat-7.0.23/bin# service tomcat start

sh: Can't open /usr/share/apache-tomcat-7.0.19/bin/startup.sh

but when i manually go and type the http://localhost:8080/ i get the apache run page...

i dont know what i have done is correct

Best Regards

Anoop

Posted by anoop on December 13, 2011 at 10:52 AM CST #

Hi Anoop

Sorry, but I'm not familair with Ubuntu.

What I can see, however, is that you have installed apache-tomcat-7.0.23, but your tomcat script is referencing apache-tomcat-7.0.19

See here:

root@anoop-Inspiron-N5010:/usr/share/apache-tomcat-7.0.23/bin# service tomcat start
sh: Can't open /usr/share/apache-tomcat-7.0.19/bin/startup.sh

Hope that helps some.

For anything more with Ubuntu, I'm afraid I'm quite useless.

Thanks,
David

One note: You should not edit catalina.sh to set options! Create a file setenv.sh in the tomcat bin directory were you set all options you need. This file is read by catalina.sh since tomcat5.

Posted by Bertl on December 22, 2011 at 03:08 AM CST #

Hi Bertl -

Its good to note the setenv.sh functionality.

Unless I am working with others and want to keep things tidy, I almost never use it.

Probably lazy, but I prefer adding a couple of lines to an existing file over creating additional files.

Thanks,
David

Brilliant tutorial.
Just a quick note, last stop/start service script is missing /bin before .sh files in their path definition.

Posted by Deniz on March 06, 2012 at 07:46 PM CST #

Hi Deniz -

Glad you found it useful.

The 'sh' is not required in the second script.

Thanks,
David

Posted by David Ghedini on March 08, 2012 at 04:33 PM CST #

Sorry, let me make myself clear,

in the last stop/start script, e.g. for the line 16, it should be /bin/su tomcat $CATALINA_HOME/bin/shutdown.sh, while it is /bin/su tomcat $CATALINA_HOME/shutdown.sh at the moment.

I hope it makes more sense now.

Posted by Deniz on March 08, 2012 at 04:43 PM CST #

Hi Deniz

If you look at the script, CATALINA_HOME is set to:

CATALINA_HOME=/usr/share/apache-tomcat-7.0.23/bin

So it already includes the /bin directory in the path

Thanks,
David

Hi David, The steps were quite clear, unfortunately, I am stuck up at Step 4, last step, I am not getting tomcat home screen after installation. Its just page cannot be displayed like tomcat is not installed at all. Your advice would be highly appreciated. Thanks, Aaron

Posted by Aaron on March 18, 2012 at 09:11 PM CDT #

On step "chkconfig --add tomcat" I get "service tomcat does not support chkconfig" anyone know why?

Posted by Eric Stob on March 23, 2012 at 12:43 PM CDT #

@Aaron -

Firstly, grep to see if tomcat is running.

If so, check that port 8080 (or whichever port you are using) is open.

David

Posted by David Ghedini on March 24, 2012 at 03:17 PM CDT #

@EricStob -

1. Check that tomcat script is executable.

2. Make sure you have:

#!/bin/bash
# description: Tomcat Start Stop Restart
#
processname: tomcat
# chkconfig: 234 20 80

At the start of the script.

Thanks,
David

Dear David, You have written an outstanding guide...

Can you also write a guide that shows how to set up multiple virtual hosts in Tomcat- for eg. one web app at http://subdomain1.domain-a.com/ and another web app at http://subdomain2.domain-b.com/ ?

I could not find a good guide that explains setting up Tomcat 7 with multiple virtual hosts.

Or if you could point me to an existing guide that shows how to do this, I would be extremely grateful.

Arvind.

Hello Devid,
Thanks for your nice article. I have followed your process but I have been facing a problem.
My web server starts with no error and the port 8080 listen but when I give a URL like localhost:8080 but it shows waiting but after few time it shows the connection was reset.
What may be the error for this kind of problem?

Hi @David thanks for reply, I solved this issue.
I removed installed open JDK using yum remove after that i downloaded rpm file from oracle using wget command then i installed downloaded rpm file using #rpm -i jdk---.rpm
Now Tomcat working fine.
Thanks again for sharing this articles.
Regards,
Vivekanand Saraswati

David, thank you for such perfect explanation!
But I still can't add tomcat to autostart via chkconfig.
My tomcat script is equal to your example:
#!/bin/bash
# description: Tomcat Start Stop Restart
# processname: tomcat
# chkconfig 234 20 80
JAVA_HOME=/usr/java/jdk1.7.0_10
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
CATALINA_HOME=/usr/share/apache-tomcat-7.0.34
case $1 in

Posted by Nikita Fyodorov on December 26, 2012 at 08:43 AM CST #

@ Nikita -

If you are unable to add the script to chkconfig, please check that you made the script executable (chmod 755 tomcat.sh).

If executable and you still get an error, try recreating the script using vi as your file may contain problems.

Thanks,
David

Thanks for this great guide, and I finally got it to start on bootup, but I had to add runtime level 5 with chkconfig --level 2345 tomcat on command. Would this be because the server is stopped when I log onto the X display manager?

Posted by Christopher Wheatley on February 01, 2013 at 10:23 PM CST #

before step 4, when you do http://yourdomain.com:8080.
in CentOS at least if u dont durn off your firewall you cant see it from another computer so if you have a virtual machine like me you just have to do this as root:

# service iptables save
# service iptables stop
# chkconfig iptables off
your manual work for me until this step. so thanks

Hi David,

This is an awesome guide. It helped me a lot.
Tomcat is successfully running on my fedora 14. But I can't access it from a remote windows 7 pc or any other linux pc.
What are step wise configuration procedure to access my tomcat and mysql database from any other remote pc?
My tomcat version is 7.0.37. Port is 8080.
Thanks in advance

Posted by Gourab Das on March 05, 2013 at 12:21 PM CST #

Hi Gourab -

Glad you found it useful.
Check your iptables.
It sounds like port 8080 is not open on your server.

Thanks,
David

Posted by David Ghedini on March 16, 2013 at 06:00 PM CDT #

Hi White_King

- I would not recommend just stopping your iptables :)

You should add a rule to either open port 8080, or use port 80 (step 7), or use Apache in front (step 8), etc...

Thanks,
David

How can I do this with only secure shell? How can I download?

Posted by Dan Howard on May 15, 2013 at 12:34 PM CDT #

Hi Dan,

You can download Tomcat using wget as shown in Step 2 above.

To download the JDK via terminal, please see my video on downloading from the OTN using wget and Firefox download manager:

[root@yomahi ~]# service tomcat start sh: /usr/share/apache-tomcat-7.0.29/bin/startup.sh: No such file or directory [root@yomahi ~]#

Posted by Mahendra on August 05, 2013 at 03:40 AM CDT #

Hi Mahendra,

Is tomcat-7.0.29 the actual version you installed?

Please check if the version in your script matches the version you have unzipped under /usr/share

Thanks,
David

Excellent instructions. Worked perfectly. You rock!

Posted by Ed Connor on August 31, 2013 at 08:20 PM CDT #

CentOS 6 is fully updated, latest versions of Java (jdk-7u25-linux-x64.tar.gz) is installed like you write, same goes for Tomcat7. Tomcat is starting, stopping, and restarting just fine. Firewall is open for 8080. However, it does not pop-up in the browser?!?!? Should be here... http://37.34.54.28:8080/

Posted by Henry den Hengst on September 05, 2013 at 09:03 AM CDT #

Thank you for such a thorough and helpful tutorial!

In step 4, one of the new roles is shown as admin-gu. Shouldn't that be admin-gui?

thanks for this great tutorial...!!! just let me know what i have to add in start/stop script so that i can able to check the status through cmd service tomcat status Thanks in advance..!!!!

Posted by vin on March 11, 2014 at 01:51 AM CDT #

Great, however in the docs (RUNNING.TXT in catalina home) says: Note: Do not use JAVA_OPTS to specify memory limits. You do not need much memory for a small process that is used to stop Tomcat. Those settings belong to CATALINA_OPTS.
