Tomcat的Manager顯示403 Access Denied

管理tomcat的時候遇到了以下問題：

　　1.剛開始需要用戶名密碼，不知道用戶名和密碼是什么，但是輸入什么都不正確。

　　解決辦法：

　　自己在tomcat-users.xml中按格式添加用戶 conf文件夾里面

　　默認是注釋掉了的，這主要是考慮到服務器的安全，如果是本地測試，去掉以下這段注釋，然后重啟動服務器，再輸入

　　 <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"/>

　　用戶和密碼都一目了然了。

 

 

　　2.進入manager界面之后，顯示的是403 Access Denied。

　　解決辦法：

　　在conf/tomcat-users.xml文件中看到這么一段話：

　　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.

　　也就是說，為了考慮安全，tomcat默認還是沒有manager-gui的管理權限的，如果想要使用manager

　　的話，需要自行加入管理權限（角色）。

　　需要加一個這樣的權限（角色）

　　<role rolename="manager-gui"/>

　　然后再加到需要的用戶名中去

　　<user username="tomcat" password="tomcat" roles="tomcat,manager-gui"/>

　　這樣OK了。
