Apache上面配置多个虚拟主机比较方便，换了VPS，资源比较紧张，自然不能再继续用apache了。lighttpd倒是个不错的选择，可是研究一下发现大型网站没人用lighttpd，倒是nginx成为不少人的首选，罢了，就用nginx吧！

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
域名2 example2.com 放在 /www/example2

配置 nginx virtual hosting 的基本思路和步骤如下：

把2个站点 example1.com, example2.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，example2.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、在 /etc/nginx/vhosts/ 里创建一个名字为 example2.com.conf 的文件，把以下内容拷进去

server {

listen 80;

server_name example2.com www. example2.com;

access_log /www/access_ example1.log main;

location / {

root /www/example2.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/example2.com/$fastcgi_script_name;

include fastcgi_params;

}

location ~ /\.ht {

deny all;

}

}

4、打开 /etc/nginix.conf 文件，在相应位置加入 include 把以上2个文件包含进来

user nginx;

worker_processes 1;

# main server error log

error_log /var/log/nginx/error.log ;

pid /var/run/nginx.pid;

events {

worker_connections 1024;

}

# main server config

http {

include mime.types;

default_type application/octet-stream;

log_format main ‘$remote_addr – $remote_user [$time_local] $request ‘

‘”$status” $body_bytes_sent “$http_referer” ‘

‘”$http_user_agent” “$http_x_forwarded_for”‘;

sendfile on;

#tcp_nopush on;

#keepalive_timeout 0;

keepalive_timeout 65;

gzip on;

server {

listen 80;

server_name _;

access_log /var/log/nginx/access.log main;

server_name_in_redirect off;

location / {

root /usr/share/nginx/html;

index index.html;

}

}

# 包含所有的虚拟主机的配置文件

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

}

5、重启 Nginx

/etc/init.d/nginx restart
