centos服务器tomcat80端口怎么开启

Tomcat服务器安装的时候默认的端口设置是8080，通常我一看到端口是8080的网站，我就猜测服务器估计是Tomcat，一般来说网站的端口普遍

是80，apache服务器的默认端口就是80，而80与8080端口有一点区别就是，如果你去访问80端口的网站，那么可以直接输入域名访问，而没必要

带上80，因为80是http协议的默认端口；但是，如果是访问8080端口的网站，那么在输入域名以后还要加上8080才行。就是因为这个繁琐的操作，

所以我每次都会修改下端口，修改方法可以参考下面：

（1）首先找到tomcat的安装路径，找到路径conf文件夹下面的server.xml文件，如下图1所示。

图1：server.xml所在路径

（2）用文本编辑器打开server.xml，修改其中端口，文件中端口有很多，比如8005，8080，8009等等，别的都可以不用管，视情况修改就好，我只修改了8080端口为80，直接查找8080替换成80就OK了，修改后的文件内容如下：

<?xml version='1.0' encoding='utf-8'?>

（3）修改server.xml文件以后，重启tomcat服务器，配置修改成功。

80是web服务，需要开启的安装web服务器

windows

用自带的IIS就可以，或者安装一个集成环境

wampserver

，安装好启动就可以，
