  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。在这个文件中添加manager角色，并为管理员添加上这种角色即可

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

   做了上面的改变如果还是有错误，请看下面：

<tomcat-users><!--  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.--><!--  NOTE:  The sample user and role entries below are wrapped in a comment  and thus are ignored when reading this file. Do not forget to remove  <!.. ..> that surrounds them.--><!--    <role rolename="tomcat"/>  <role rolename="role1"/>  <role rolename="manager"/>  <user username="admin" password="admin" roles="manager"/>  <user username="tomcat" password="tomcat" roles="tomcat"/>  <user username="both" password="tomcat" roles="tomcat,role1"/>  <user username="role1" password="tomcat" roles="role1"/>--></tomcat-users>

把红色的线去掉就可以了，因为<!-->所包括的东西是要被忽略的，相当于注释的作用！
