无法访问manager-gui tomcat8

Question

我在Ubuntu 15.10上安装了tomcat8，当我去的时候，我得到了通常的欢迎屏幕：

http://myhost:8082/

（我在server.xml中将端口重新配置为8082）。

但我无法访问经理gui：

http://myhost:8082/manager/html

我在 /etc/tomcat8/tomcat-users.xml 文件中尝试了以下操作，然后重新启动tomcat8：

sudo /etc/init.d/tomcat8 restart

以下是我尝试过的修改内容：

1）

 <role rolename="manager-gui"/>
 <user username="admin" password="12345" roles="manager-gui"/>

2）

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

我发现其他SO帖子和博客都描述了新的方式，因此配置用户/角色但没有一个工作。相反，我一直得到：

cat catalina.out

看起来您根本没有安装经理应用。默认情况下，它没有安装ubuntu的tomcat。在Ubuntu 14.04中有一个包tomcat7-admin - 我假设您可以在15.10中找到tomcat8-admin - 检查aptitude search tomcat的结果并验证可用的包，然后sudo aptitude install tomcat8 -admin。

安装时，请记住正确保护它 - 您不应该在生产系统中使用它而不明确限制谁有权访问它（不仅仅是用户名/密码）
