多域名Nginx配置

            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

            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/;
}

/data/wwwsite/domain.com/www/
