1：修改tomcat-users.xml
 
找到Tomcat的安装目录，进入到conf目录中，打开tomcat-users.xml文件，配置如下内容：
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/> 
  <role rolename="manager-gui"/>
  <role rolename="admin"/>  
  <role rolename="admin-gui"/>  
  <role rolename="manager-script"/>  
  <role rolename="manager-jmx"/>  
  <role rolename="manager-status"/> 
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
  <user username="admin" password="admin" roles="tomcat,role1"/>
  <user username="tomcat" password="" roles="manager-gui"/>
  <user username="Tomcat" password="Tomcat" roles="admin-gui,admin,manager-gui,manager,manager-script,manager-jmx,manager-status"/>

2：配置远程访问
 
 
修改tomcat管理功能配置文件（<tomcat>/webapps/manager/META-INF/context.xml），注释掉地址限制：
<Context antiResourceLocking="false" privileged="true" >
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
</Context>
改为
<Context antiResourceLocking="false" privileged="true" >
    <!--
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
    -->
</Context>
