Tomcat download installation and configuration

tomcat download link: https://tomcat.apache.org/
1. After entering the tomcat official website, select the version you want to download. I use tomcat9, so here I choose tomcat9
2. Choose zip (pgp, sha2, sha512) to download. The advantage of downloading zip is that you don't need to install it, just download and unzip it directly.
3. The download is complete.

PathPath=%CATALINA_HOME%\lib
%CATALINA_HOME%\lib\servlet-api.jar
%CATALINA_HOME%\lib\jsp-api.jar
5. Add a user and enter the conf of the tomcat9 directory. My path here is D:\ProgramFiles\apache-tomcat-9.0.0.M26\conf,
Select the "tomcat-users.xml" file, open the file and add the following code before the last line of code:
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="admin" password="admin" roles="admin-gui"/>
<user username="tomcat" password="admin" roles="manager-gui"/>
6. After adding, save and exit.
