192.168.55.115為主伺服器

192.168.55.185為從伺服器

先需要將發送到伺服器端的請求進行分流，具體要求如下

要求/index.php/*的請求訪問主伺服器

/api.php/1/files/*的請求訪問主伺服器

/api.php/1/files_put/*的請求訪問主伺服器

/api.php/1/thumbnails/*的請求訪問主伺服器

/statics/thumbnails/*的請求訪問主伺服器

其它的都訪問從伺服器

其中

                set $script $uri;                set $path_info "";                if ($uri ~ "^(.+.php)(/.+)") {                        set $script $1;                        set $path_info $2;                }

的設定是為了配置php的$_Server[''path_info"]擷取了全路徑的問題， 具體請參考 這裡
