配置 Nginx 的 location 处理 cgi 文件：
location ~ .*\.cgi$ {
fastcgi_pass127.0.0.1:8999;
fastcgi_paramSCRIPT_FILENAME $document_root$fastcgi_script_name;
includefastcgi_params;
}
测试：
在 web 的根目录下创建一个 cgi 文件：
vi test.cgi
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello, world.";
文件需要有可执行权限：
chmod +x test.cgi
访问 http://www.domain.com/test.cgi 看看有没有输出。
