Solve the installation of the administration Web Application in Tomcat

In the past few days, we found that the admin module was no longer available after Tomcat 5.5.12. When Tomcat was entered, Tomcat's administration Web application is no longer installed by default appeared.
Download and install the "admin" package to use it. then I got depressed. I went to the Apache website and found the download of the administration Web application module. After the result, I found that I didn't know how to use it. I went to Google to get it, I have read several articles ArticleEvery time you see something.
First, install Tomcat first. I won't talk about how to install it. I want to use the admin module to know how to install it successfully. I won't be able to check it on my website, there are many articles.
Go to the administration Web application management package apache-atat-5.5.12-admin.zip under Apache and decompress the package. There are two directories, conf and server, and three description files respectively. The description file can be viewed. Copy the admin. xml file under/CONF/Catalina/localhost to the/CONF/Catalina/localhost directory under the tomcat installation directory. Then, test the admin folder under the server/webapps directory to the server/webapps directory under the tomcat security folder. Then open http: // 127.0.0.1: 8080/and start the admin service in the manager. Then, go to the admin module and everything is OK.
