## 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。

<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>

<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-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

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。
