1. 确保tomcat下原来自带的几个项目未被删掉，tomcat启动时localhost:8080能直接访问tomcat主页

2. 修改tomcat下 conf/tomcat-users-xml文件，找到tomcat-users标签，按照下面的加上配置

        注： username: 用户名， password：密码   自己根据需求做修改

<tomcat-users xmlns="http://tomcat.apache.org/xml"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
              version="1.0">
        <role rolename="manager"/>
        <role rolename="manager-gui"/>
        <user username="admin" password="admin" roles="manager,manager-gui"/>
</tomcat-users>

3. 修改 tomcat/webapps/manager/META-INF/context.xml,注释掉context标签下的所有代码，否则会出现无访问权限的问题

<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" />
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
-->
</Context>

4. 登录tomcat首页，点击 Server Status 登录到管理界面
