How to uninstall and reinstall Tomcat (with pictures and text)

Uninstall tomcat9

1. Since the installation of Tomcat only needs to be unzipped to a directory, uninstallation also only needs to delete the original Tomcat directory

2. Delete the relevant registry. Press the shortcut key win+R to call out "Run", enter "regedit" and press Enter, click Agree to call out the registry management interface, press ctrl+F to find the relevant files of tomcat, enter "tomcat" to search and delete them one by one

3. Run cmd as an administrator and execute the command sc delete tomcat9 (the tomcat version I installed before is tomcat89.0.17, depending on your own version), delete the tomcat service

Uninstall successful!
You can start reinstalling now

Install Tomcat

Download tomcat and unzip it to a directory. I downloaded apache-tomcat-9.0.17-windows-x64 and unzipped it in my D drive, D:\apache-tomcat-9.0.17

Set environment variables in My Computer –> Properties –> Environment Variables

CATALINA_HOME=D:\apache-tomcat-9.0.17 (decompression directory)

Add %CATALINA_HOME\bin%;%CATALINA_HOME\lib% to PATH

After configuring the environment variables, open cmd as an administrator, enter the bin folder in Tomcat, and execute service.bat install

If the installation is successful, you can drag the startup.bat in the bin directory to the cmd window to start tomcat to verify whether the installation is successful.

Oh. Garbled? !

Solution to cmd garbled code when running tomcat

Open notepad++ and press ctrl+F to locate the current position.
