tomcat-常见配置详解

在conf/server.xml 有以下内容

8005是Tomcat的管理端口，默认监听在127.0.0.1上。无需认验，就可发送SHUTDOWN这个字符串，tomcat接收到后就会关闭此Server。这个管理功能建议禁用，改shutdown为一串猜不出的字符串，比如以下示例

范例：修改8005/tcp端口管理命令

conf/server.xml中可以配置service，connector, Engine,Host等

service配置

一般情况下，一个Server实例配置一个Service，name属性相当于该Service的ID。

连接器配置

redirectPort，如果访问HTTPS协议，自动转向这个连接器。但大多数时候，Tomcat并不会开启HTTPS，因为Tomcat往往部署在内部，HTTPS性能较差

引擎配置

defaultHost 配置

defaultHost指向内部定义某虚拟主机。缺省虚拟主机可以改动，默认localhost。
