nginx 设置限制ip访问

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;
