Tomcat Failed

by Victoria @ 6:25 am. Filed under cPanel Hosting, Java, Web Hosting Articles, JSP Servlet Hosting

If tomcat is failed on the server, Then login to the server with root login details and Goto, ————————-

cd /usr/local/jakarta/jakarta-tomcat-5.5.9/bin/

————————-

Check the running processes as

ps aux | grep tomcat

Then stop all tomcat processes. You can stop it with the script as ————————-

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# ./shutdown.sh ————————- [This script will stop the tomcat processes that are running]

In order to fix tomcat run following command under /usr/local/jakarta/jakarta-tomcat-5.5.9/bin

————————-

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# java -jar bootstrap.jar

————————- [This will set java environment for tomcat on the server]

Then start the tomcat service with the script

————————-

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# ./setclasspath.sh

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# ./startup.sh ————————- [This script start tomcat on the server]

You will have to stop and restart apache service on the server many times before you run startup.sh script.

Uninstalling Tomcat

by Angelo @ 10:51 am. Filed under Linux Hosting, JSP Servlet Hosting

Dont uninstall it, just leave it alone but stop tomcat. It would take a rocket scientist to find all occurances of tomcat splashed all over your HD. Here is how you can stop it! This is what i did.
Tomcat is a nuisance and a resource hog!

First stop it:

/usr/sbin/stoptomcat

Then /etc/httpd/conf

pico httpd.conf and find all occurances of the word mod_jk. Comment out all the mod_jk lines. Then find the includes line and comment that out. Now find index.jsp and remove that if installed.

Exit out, save and restart apache /etc/rc.d/init.d/httpd restart

Now load ntsysv

/usr/sbin/ntsysv

Scroll down until you find tomcat and toggle the star to blanks, [ ]

Save, exit out. You have now disabled it from starting at bootup.

If you added it to services for monitoring then remove it from /etc/chkserv.d and also from /var/run/chkservd/ then restart chkserver.

Your done!
