Tomcat的后台管理功能
配置 Tomcat 后台授权用户
1 | [root@iZuf6iq8e7ya9v3ix71k0pZ tomcat]# vim tomcat-8081/conf/tomcat-users.xml |
刷新manager.html页面，还是403，后面重新启动tomcat,403,这就奇怪了…
还是403
后面查看相关tomcat官网，还需要此manager.xml文件，赋予远程管理的权限
Each deployed webapp has a context.xml file that lives in $CATALINA_BASE/conf/[enginename]/[hostname] (conf/Catalina/localhost by default) and has the same name as the webapp (manager.xml in this case). If no file is present, default values are used.
So, you need to create a file conf/Catalina/localhost/manager.xml and specify the rule you want to allow remote access.1

重新启动 tomcat，刷新manger.html
