2.CodeIgniter配置注意事项如下：
$config['base_url'] = 'http://192.168.55.88:85/';//注意与nginx中设置的server_name保持一致
$config['index_page'] = '';//从url中隐藏index.php文件
$config['allow_get_array'] = TRUE;
$config['enable_query_strings'] = FALSE;//关闭查询字符串形式的url路由
$config['controller_trigger'] = 'c';
$config['function_trigger'] = 'm';
$config['directory_trigger'] = 'd'; // experimental not currently in use
3.问题:
1)81端口尚未测试（与85端口不同的部分可能会出现问题）
2)如果出现502 bad gateway错误则可能需要启动php-cgi，请参考本博客【FreeBSD下spawn-fcgi启动与关闭】，重新启动fcgi
3)关于以上正则匹配中出现的匹配符～*（网上参考时很多出现这个匹配符号），个人理解nginx中配置时是以perl兼容的正则表达式方式匹配的，所以，正确写法应该是～，经测试发现两者都不影响服务器运行，即都有效，这是目前本人尚不清楚的地方...有知道的大大请帮忙解答下
4）关于fcgi不自动启动的疑问尚未解决,即以上配置中的这句fastcgi_pass 127.0.0.1:9000;在配置完后重新启动nginx（service nginx restart）时用sockstat -l命令或netstat -anl命令查看本地监听的端口时，并未发现9000端口已开启监听
