tomcat默认密码,admin,manager密码需要自己设置，tomcat-users.xml

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

 
  后面加上一条就可以了   
     

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

 后加的是意思是设置admin和manager的用户名和密码为admin
