nginx限制IP访问

时间:2022-08-05 16:58:37




一、服务器全局限IP


#vi nginx.conf


    allow 10.57.22.172;  #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 10.57.22.172;
    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 10.57.22.172;
    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 127.0.0.0/24;
           allo w 192.168.0.0/16;
           allow 10.10.0.0/16;
           deny all;
