Apache Tomcat or simply Tomcat (formerly it was also known as Jakarta Tomcat) is an open source web server and servlet container developed by the Apache Software Foundation (ASF). Tomcat can be installed on CentOS/Redhat machine either using yum or from the source file. However, in this tutorial, we will see, how we can uninstall/remove tomcat from the Linux machine.
In order to remove tomcat from your machine, the first thing you need to check is how this package got installed on your server.
Removal of Tomcat installation through package manager
Suppose, you have installed tomcat 5 or tomcat 7 using yum package manager, then the default tomcat configurations can be found at “/etc/tomcat5” and “/usr/share/tomcat5”. You can find the tomcat packages using the following command:
# rpm –qa | grep tomcat
Now, you can proceed with uninstallation of the listed packages using “yum” as follows:
# yum remove tomcat5 # yum remove tomcat5-webapps # yum remove tomcat5-admin-webapps
Continue this for the other packages. Packages such as tomcat5-servelet may have many dependencies including open office. So, if you want to remove the packages without removing the dependencies, you need to use the command “rpm” as follows:
# rpm –e package_name –nodeps
After removing the packages, you need to remove the tomcat directories too:
# rm –rf /etc/tomcat5 # rm –rf /usr/share/tomcat5
On Ubuntu to remove system and config files run below commands
sudo apt remove --purge tomcat7 tomcat7-docs sudo apt autoremove sudo apt autoclean
You can locate and manually delete the remaining files if any exists.
sudo apt install locate && sudo updatedb locate tomcat
To remove just the tomcat7 package
sudo apt-get remove tomcat7
To remove tomcat7 package and its dependent packages
sudo apt-get remove --auto-remove tomcat7
This will delete all local/config files and cant be restored
sudo apt-get purge tomcat7 sudo apt-get purge --auto-remove tomcat7
Removal of Tomcat source file installation
In this case, you need to stop tomcat and remove all the binaries from the server.
1. To stop tomcat
Lets first stop the service.
2. To remove tomcat binaries and folders
Remove all occurence of tomcat binary files and folders from the below locations
#rm -f /usr/sbin/startomcat #rm -f /usr/sbin/stoptomcat #rm -Rf /usr/local/jakarta
3. To remove from 'chkservd'
Stop chkservd and remove tomcat from there if it is configured.
# service chkservd stop #cd /etc/chkserv.d #rm -Rf tomcat #cd /var/run/chkservd rm -Rf Tomcat_JSP #service chkservd start
4. To remove Tomcat Connector configuration from Apache web server
Remove all mod_jk lines from httpd.conf, including addmodule, loadmodule, and include lines.
