nginx的详细配置

nginx的详细配置

1 配置虚拟主机

就是在一台服务器启动多个网站。

如何区分不同的网站：主要有以下两种方式

方式一：端口不同

方式二：域名不同

2 通过端口区分不同的主机和多个域名区分虚拟主机

nginx配置文件的位置：/usr/local/nginx/conf/nginx.conf

原始配置文件的内容如下：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}
