tomcat查看服务器状态之角色配置

1、查看官方说明

2、查看web.xml

       该web.xml是指：/webapps/manager/WEB-INF下的web.xml。

       

  <!-- Define the Manager Servlet Mapping -->
  <servlet-mapping>
    <servlet-name>Manager</servlet-name>
      <url-pattern>/text/*</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>Status</servlet-name>
    <url-pattern>/status/*</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>JMXProxy</servlet-name>
      <url-pattern>/jmxproxy/*</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>HTMLManager</servlet-name>
    <url-pattern>/html/*</url-pattern>
  </servlet-mapping>

      

  <!-- Define a Security Constraint on this Application -->
  <!-- NOTE:  None of these roles are present in the default users file -->
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>HTML Manager interface (for humans)</web-resource-name>
      <url-pattern>/html/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-gui</role-name>
    </auth-constraint>
  </security-constraint>
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>Text Manager interface (for scripts)</web-resource-name>
      <url-pattern>/text/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-script</role-name>
    </auth-constraint>
  </security-constraint>
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>JMX Proxy interface</web-resource-name>
      <url-pattern>/jmxproxy/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-jmx</role-name>
    </auth-constraint>
  </security-constraint>
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>Status interface</web-resource-name>
      <url-pattern>/status/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-gui</role-name>
       <role-name>manager-script</role-name>
       <role-name>manager-jmx</role-name>
       <role-name>manager-status</role-name>
    </auth-constraint>
  </security-constraint>

具体的角色名称 

<!-- Security roles referenced by this web application -->
  <security-role>
    <description>
      The role that is required to access the HTML Manager pages
    </description>
    <role-name>manager-gui</role-name>
  </security-role>
  <security-role>
    <description>
      The role that is required to access the text Manager pages
    </description>
    <role-name>manager-script</role-name>
  </security-role>
  <security-role>
    <description>
      The role that is required to access the HTML JMX Proxy
    </description>
    <role-name>manager-jmx</role-name>
  </security-role>
  <security-role>
    <description>
      The role that is required to access to the Manager Status pages
    </description>
    <role-name>manager-status</role-name>
  </security-role>

• manager-gui — Access to the HTML interface.
• manager-status — Access to the "Server Status" page only.
• manager-script — Access to the tools-friendly plain text interface that is described in this document, and to the "Server Status" page.
• manager-jmx — Access to JMX proxy interface and to the "Server Status" page.
• 若设置了manager-jmx 或manager-script  就不用设置manager-status角色了，因为这两个角色默认是包含的

3、配置tomcat-users.xml

     该文件在目录：tomcat/conf下，配置一个管理员用户包含所有角色

 <role rolename="manager-gui"/>
 <role rolename="manager-script"/>
 <role rolename="manager-jmx"/>
 <role rolename="manager-status"/>
 <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx"/>

   配置完成后，需要重启tomcat服务。

4、查看tomcat状态

       tomcat启动后，点击Server Status按钮，查看服务器状态，点击后，输入上一步配置的用户名和密码：admin，登录查看

服务器状态：

注：如果不用web部署功能查看服务器状态,建议删除webapps目录下的内容,这样你的tomcat启动速度会变快,并且其他人也不能通过这个地址来访问，变得更安全。但有的框架会调用这个目录下的内容，请根据具体情况，决定是否删除。
