管理 Tomcat 的时候遇到了以下问题:
 
1. 刚开始需要用户名密码,不知道用户名和密码是什么,但是输入什么都不正确。
 
解决办法:
 
自己在 tomcat-users.xml 中按格式添加用户 conf 文件夹里面
 
默认是注释掉了的,这主要是考虑到服务器的安全,如果是本地测试,去掉以下这段注释,然后重启动服务器,再输入
 
<role rolename=”tomcat”/>
 
<role rolename=”role1″/>
 
<user username=”tomcat” password=”tomcat” roles=”tomcat”/>
 
<user username=”both” password=”tomcat” roles=”tomcat,role1″/>
 
<user username=”role1″ password=”tomcat” roles=”role1″/>
 
用户和密码都一目了然了。

2. 进入 manager 界面之后,显示的是 403 Access Denied。
 
解决办法:
 
在 conf/tomcat-users.xml 文件中看到这么一段话:
 
NOTE: By default, no user is included in the “manager-gui” role required
 
to operate the “/manager/html” web application. If you wish to use this app,
 
you must define such a user – the username and password are arbitrary.
 
也就是说,为了考虑安全,tomcat 默认还是没有 manager-gui 的管理权限的,如果想要使用 manager
 
的话,需要自行加入管理权限(角色)。
 
需要加一个这样的权限(角色)
 
<role rolename=”manager-gui”/>
 
然后再加到需要的用户名中去
 
<user username=”tomcat” password=”tomcat” roles=”tomcat,manager-gui”/>
 
这样 OK 了。
