Tomcat管理器应用程序已部署并正确配置但返回404

Question

我相信我已经正确配置Tomcat以在端口8080上运行并启用了管理器，但是当我尝试访问它时我得到404.

tomcat正在8080上运行

$ netstat -apn | grep 8080 | grep LISTEN
(Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:8080                0.0.0.0:*                   LISTEN      31068/java

经理部署WAR

$ ls webapps/ | grep manager
drwxr-xr-x  5 voops voops     4096 Dec  2 12:34 host-manager/
drwxr-xr-x  5 voops voops     4096 Dec  2 12:34 manager/

经理已正确配置

$ find . -iname manager.xml
./webapps/host-manager/manager.xml
$ tail -4 ./webapps/host-manager/manager.xml
<Context docBase="${catalina.home}/webapps/manager"
         privileged="true" antiResourceLocking="false" antiJARLocking="false">

</Context>

尝试访问经理时

404

$ wget localhost:8080/manager
--2015-04-23 15:03:38--  http://localhost:8080/manager
Resolving localhost... 127.0.0.1, ::1

（尝试localhost:8080/manager/html时的结果与上述相同）。请注意，部署在同一Tomcat中的其他应用程序似乎正常工作。只有内置管理器应用程序似乎失败了。
