Tomcat管理器在ubuntu droplet上显示403

Question

我已经采购了数字海洋的ubuntu水滴，我在配置访问tomcat管理器时遇到了问题。我已经按照下面的教程一步一步地完成了所有步骤-- https://cloud.digitalocean.com/support/suggestions?article=how-to-install-apache-tomcat-8-on-ubuntu-14-04&page=0&query=tomcat%20manager

实际上，我可以在server-ip:8080上访问tomcat主页，但在manager/html上遇到访问被拒绝的问题

这是我的tomcat-users.xml-

<?xml version='1.0' encoding='utf-8'?>

</tomcat-users>

我尝试了我的用户和角色组合，但每次都被拒绝访问。请帮帮忙

您需要为管理器应用程序创建上下文，并允许从Tomcat 8.5.x进行访问

在您的$CATALINA_BASE/conf/Catalina/localhost/主目录下创建文件manager.xml

manager.xml内容，请注意我的来源是172.31.254.37 (我的电脑)，请将其更改为您的来源：

<Context privileged="true" antiResourceLocking="false"
         docBase="${catalina.home}/webapps/manager">
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="172\.31\.254\.37" />
</Context>

确保在$CATALINA_BASE/conf/tomcat-users.xml中定义了您的用户/角色

<user username="tomcat" password="tomcat" roles="manager-gui,manager-status"/>

如果需要，您需要对host-manager执行相同的操作
