如何利用自己的电脑做服务器发布tomcat的WEB项目供外网访问

1、首先你要确定你有一个外网ip地址。如果你分配到的是一个局域网IP地址需要经过一系列的转换为外网ip地址，然后继续下面操作。

2、拿到外网IP地址，进行tomcat的server.xml文件的配置。主要进行下面三个地方的配置（本次配置采用的tomcat版本号是7.0.27）

1）<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> 将port端口改为80，基于http协议一般是通过80端口访问的，这样可以避免每次都输入8080的麻烦。

2）<Engine name="Catalina" defaultHost="171.35.52.187"> 将defaulHost的localhost改变为你自己的外网ip地址，提供给外面访问。

3）<Host name="171.35.52.187" appBase="webapps" unpackWARs="true" autoDeploy="true">

<Context path="test" docBase="D:/SudentManager" reloadable="true" crossContext="true"></Context> 将Host 里的name改为外网IP地址，同时在该标签里加入Context标签，内容如上，path 代表访问的虚拟路径，docBase代表的是实际项目路径。

经过上面三步的配置，已经实现了服务器的配置。我们就可以启动Tomcat，此时通过ip地址可以直接访问该项目啦。

以上的方法完全适应局域网内使用。
