这里以配置2个站点(2个域名)为例，n 个站点可以相应增加调整，假设：

IP地址: 202.55.1.100

域名1 example1.com 放在 /www/example1

配置 nginx virtual hosting 的基本思路和步骤如下：

把这个站点 example1.com放到 nginx 可以访问的目录 /www/

给每个站点分别创建一个 nginx 配置文件 example1.com.conf, 并把配置文件放到 /etc/nginx/vhosts/

然后在 /etc/nginx.conf 里面加一句 include 把步骤2创建的配置文件全部包含进来(用 * 号)

重启 nginx

具体过程

下面是具体的配置过程：

1、在 /etc/nginx 下创建 vhosts 目录

mkdir /etc/nginx/vhosts

2、在 /etc/nginx/vhosts/ 里创建一个名字为 example1.com.conf 的文件，把以下内容拷进去

server {

listen 80;

server_name example1.com www. example1.com;

#access_log /www/access_ example1.log main;

location / {

root /www/example1.com;

index index.php index.html index.htm;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root /usr/share/nginx/html;

}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

location ~ \.php$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /www/example1.com/$fastcgi_script_name;

include fastcgi_params;

}

location ~ /\.ht {

deny all;

}

}

3、打开 /etc/nginix.conf 文件

将下面这句在nginx.conf 文件的最后一行，目的引入刚才的vhosts文件

include /usr/local/etc/nginx/vhosts/*;

5、重启 Nginx

/etc/init.d/nginx restart

或者 kill -HUP `cat /var/run/nginx.pid`     cat 后面跟的是nginx进程pid  如果不知道nginx.pid文件的位置可以用find / -name nginx.pid 命令来查找

或用yum源码包安装的nginx可以直接service nginx restart
