升级ECS系统后，OCS不能连接了

【已解决】：阿里升级硬件的时候给我更换了IP，OCS的IP防火墙忘记修改了！！！！重新修改一下IP防火墙就OK了


大概背景：将ECS系统盘升级到 Centos6.5后，wordpress连接OCS一直提示错误！


错误信息：


Fatal error: Uncaught exception 'Exception' with message 'Auth failure.' in /home/wp/wp-content/MemcacheSASL.php:124 Stack trace: #0 /home/wp/wp-content/object-cache.php(409): MemcacheSASL->setSaslAuthData('ec157...', 'ocspassword') #1 /home/wp/wp-content/object-cache.php(103): WP_Object_Cache->load_from_config(Array) #2 /home/wp/wp-includes/load.php(476): wp_cache_init() #3 /home/wp/wp-settings.php(95): wp_start_object_cache() #4 /home/wp/wp-config.php(104): require_once('/home/test/...') #5 /home/wp/wp-load.php(37): require_once('/home/test/...') #6 /home/wp/wp-blog-header.php(13): require_once('/home/test/...') #7 /home/wp/index.php(17): require('/home/test/...') #8 {main} thrown in /home/wp/wp-content/MemcacheSASL.php on line 124


注：setSaslAuthData 连接账户密码部分反复核对了，并重新修改了

配置参考的是阿里帮助官网：
