nginx 限制IP

一、服务器全局限IP

#vi nginx.conf

    allow x.x.x.x;  #允许的IP
    deny all;


二、站点限IP

#vi vhosts.conf

站点全局限IP:
location / {
    index  index.html index.htm index.php;
    allow x.x.x.x;
    deny all;

    location ~ \.php$ {
        if ( $fastcgi_script_name ~ \..*\/.*php ) {return 403;}
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /var/www/htdocs$fastcgi_script_name;
        include fastcgi_params;
    }
}

站点IP限目录:
location / {
    index  index.html index.htm index.php;
}

location ^~ /test/ {
    allow x.x.x.x;
    deny all;

    if ( $fastcgi_script_name ~ \..*\/.*php ) {return 403;}
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /var/www/htdocs$fastcgi_script_name;
    include fastcgi_params;
}

location ~ \.php$ {
    if ( $fastcgi_script_name ~ \..*\/.*php ) {return 403;}
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /var/www/htdocs$fastcgi_script_name;
    include fastcgi_params;
}

 

注意事项:

  1. deny 一定要加一个ip,否则直接跳转到403,不往下执行了;如果403默认页是同一域名下,会造成死循环访问;

  2. allow的ip段

  从允许访问的段位从小到大排列,如127.0.0.0/24 下面才能是10.10.0.0/16

  24表示子网掩码:255.255.255.0

  16表示子网掩码:255.255.0.0

  8表示子网掩码:255.0.0.0

  3. deny all;结尾 表示除了上面allow的其他都禁止

如:

           deny 192.168.1.1;

           allow 192.168.1.0/24;

           allow 192.168.0.0/16;

           allow 192.0.0.0/8;

           deny all;
