多域名Nginx配置

例如有两个域名,指向同一个服务器IP

www.domain1.com

www.domain2.com

我建立两个目录, 存放网站文件

/var/www/domain1.com/public

/var/www/domain2.com/public

nginx配置文件为:

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    server_name ~^(www\.)?(.+)$;
    set   $domain  $2;
    root /var/www/$domain/public;
    index index.php index.html index.htm;

    if ($host = domain1.com){
         rewrite ^ http://www.domain1.com permanent;
    }

    if ($host = domain2.com){
         rewrite ^ http://www.domain2.com permanent;
    }

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~* \.(gif|jpg|jpeg|mp4|mp3|wav|ogg|flv)$ {
        expires 30d;
        valid_referers *.domain1.com *.domain2.com ~\.baidu\.com;
        if ($invalid_referer) {
            rewrite ^/ http://domain1.com;
            #return 404;
        }
    }

}

注意:

set   $domain  $2;
root /var/www/$domain/public;

不能直接用

root /var/www/$2/public;

不然

location ~ \.php$

会解析错误

如果在一个server块中为一个站点配置多个二级域名配置如下:

server  {
     listen       80;
     server_name  ~^(.+)?\.domain\.com$;
     index index.html;     # 将domain.com 重定向到 www.domain.com
     if ($host = domain.com){
         rewrite ^ http://www.domain.com permanent;
     }
     root  /data/wwwsite/domain.com/$1/;
}

站点目录结构如下:

/data/wwwsite/domain.com/www/
/data/wwwsite/domain.com/nginx/
