Download Tomcat

1. Go to the official website http://tomcat.apache.org/, select download, and download the desired Tomcat version.

Here we choose to download the latest version of Tomcat 9.

Note that there are two formats: zip and exe, zip (64-bit Windows zip (pgp,md5,sha1)) is installation-free, and exe (32-bit/64-bit Windows Service installer (pgp,md5,sha1)) is installed. At the same time, observe whether your computer is a 64-bit system or a 32-bit system.

Choose to download the zip version here

Decompress directly after download

Variable value: d:\ tools\ apache-tomcat-8.5.4

Click OK.

Add% CATALINA_HOME%\ lib\ servlet-api.jar; to the variable value of ClassPath (pay attention to the ";" in English state after the original variable value)

Add% CATALINA_HOME%\ bin;%CATALINA_HOME%\ lib to the variable value of Path (pay attention to the ";" in English state after the original variable value)
