登陆远程服务器的Tomcat 8的manger的页面403

访问远程服务器Tomcat 8的管理页面报错

在远程服务器上安装了一个tomcat8.5,配置好用户后重新启动tomcat ,发现:8080可以访问，但是进入:8080/manager/html页面报403访问受限，具体报错信息如下:

403 Access Denied
You are not authorized to view this page.
By default the Manager is only accessible from a browser running on the same machine as Tomcat. If you wish to modify this restriction, you'll need to edit the Manager's context.xml file.
If you have already configured the Manager application to allow access and you have used your browsers back button, used a saved book-mark or similar then you may have triggered the cross-site request forgery (CSRF) protection that has been enabled for the HTML interface of the Manager application. You will need to reset this protection by returning to the main Manager page. Once you return to this page, you will be able to continue using the Manager application's HTML interface normally. If you continue to see this access denied message, check that you have the necessary permissions to access this application.
If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation. That file must contain the credentials to let you use this webapp.
For example, to add the manager-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above.

网上搜了很多，但都不可行，最后在stack overflow上看到正解，所以记录保存下，修改

/webapps/manager/META_INF/context.xml文件，将文件中对访问的来源受限设置注释:

<Context antiResourceLocking="false" privileged="true" >
  <!--注释这里，去除对访问权限的设置
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
         -->
</Context>

然后直接刷新页面就行了，无需重启tomcat。
