进入Tomcat Manager出现 HTTP Status 403错误

      Tomcat 解压版解压后，启动tomcat，输入http://localhost:8080即可进入主页面，要进入Tomcat Manager得先进行配置，进入tomcat解压目录->conf，对tomcat-users.xml进行修改。

初始如下：

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
   <role rolename="tomcat"/>
   <role rolename="role1"/>
   <user username="tomcat" password="tomcat" roles="tomcat"/>
   <user username="role1" password="tomcat" roles="role1"/>
   <user username="both" password="tomcat" roles="tomcat,role1"/>
</tomcat-users> 

修改后如下：

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
   <role rolename="tomcat"/>
   <role rolename="role1"/>
   <role rolename="manager"/>
   <role rolename="admin"/>
   <user username="admin" password="admin" roles="admin,manager"/>
   <user username="tomcat" password="tomcat" roles="tomcat"/>
   <user username="role1" password="tomcat" roles="role1"/>
   <user username="both" password="tomcat" roles="tomcat,role1"/>
</tomcat-users>

重启tomcat，就可以admin，admin进入了！

注：最好把<user username="admin" password="admin" roles="admin,manager"/>放前面，否则有可能还会出错，我就出现这种情况了，有点费解！
