摘要

这个模块创建一些变量，其值依赖于客户端的IP地址.

示例配置:

geo  $geo  {
  default          0;
  127.0.0.1/32     2;
  192.168.1.0/24   1;
  10.1.0.0/16      1;
}

指令

geo

语法: geo [$ip_variable] $variable { ... }

默认值: none

语境: http

这个指令指定了一个客户端IP的所属国家，默认情况下它会查找$remote_addr变量，但在0.7.27版 本以后可以手工指定。

 geo  $arg_remote_addr $geo {
   ...;
 }

使用CIDR地址格式，另外，有4个特殊的参数:

示例说明:

• delete – 删除指定的网络 (0.7.23).
• default - the value of variable, if the client address does not correspond to any assigned address. It is possible so to write instead of default 0.0.0.0/0.
• include - text file with addresses and values information. Several files can be inluded like this.
• proxy - specifies the address of proxy server (0.8.7+). NEED MORE DESCRIPTION...
• ranges – specifies that the addresses specified are in the form of ranges (0.7.23). This directive must be the first.

 geo  $country  {
   default          no;
   include          conf/geo.conf;
   127.0.0.0/24     us;
   127.0.0.1/32     ru;
   10.1.0.0/16      ru;
   192.168.1.0/24   uk;
 }

In the file conf/geo.conf:

 10.2.0.0/16      ru;
 192.168.2.0/24   ru;

The value will be the the one with maximum agreement. For example, the IP address 127.0.0.1 will get the value "ru", but not "us".

Example with ranges:

 geo  $country  {
   ranges;
   default                    no; 
   127.0.0.0-127.0.0.0        us;
   127.0.0.1-127.0.0.1        ru;
   127.0.0.1-127.0.0.255      us;
   10.1.0.0-10.1.255.255      ru;
   192.168.1.0-192.168.1.255  uk; 
 }
