Tomcat 总是返回状态码 400

Question

我刚刚在 CentOS 6.3 上安装了 Tomcat。

# yum install tomcat6
# service tomcat6 start

根据我看过的教程，我现在应该能够看到一个测试页面。

# curl -I 127.0.0.1:8080
HTTP/1.1 400 Bad Request
...

# curl -I 127.0.0.1:8080/manager/html
HTTP/1.1 400 Bad Request
...

为什么我在这里得到400？还有什么我需要配置的吗？

Tomcat 总是返回状态码 400

因为webapps目录是空的：

# ls -l /usr/share/tomcat6/webapps/
total 0

https://issues.apache.org/bugzilla/show_bug.cgi?id=50734

创建一个虚拟ROOT上下文以获得 404 状态：

# mkdir /usr/share/tomcat6/webapps/ROOT

# ls -l /usr/share/tomcat6/webapps/
total 4
drwxr-xr-x 2 root root 4096 Feb 22 07:47 ROOT

# service tomcat6 restart
Stopping tomcat6:                                          [  OK  ]
Starting tomcat6:                                          [  OK  ]

# curl -I localhost:8080

或者...安装tomcat6-webapps软件包以获得 200：

yum info tomcat6-webapps
