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 Stream /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 9 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 the 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 tomcat9 tomcat9-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
To remove just the tomcat9 package
sudo apt-get remove tomcat7
To remove tomcat9 package and its dependent packages
sudo apt-get remove --auto-remove tomcat9
This will delete all local/config files and can't be restored
sudo apt-get purge tomcat9
sudo apt-get purge --auto-remove tomcat9
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
Let's first stop the service.
2. To remove tomcat binaries and folders
Remove all occurrences 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
rm -Rf tomcat
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.
In this guide, we learned how to completely remove tomcat from Linux distributions such as Ubuntu.
