无法写入会话数据，php和memcached [英] Failed to write session data, php and memcached

问题描述

我最近尝试了实现memcached以便将会话保存在php中. 我在php.ini中修改了session.save_handler，并且在大多数情况下可以正常工作.会话被保存在其中.但是，有时我会在某些会话中收到以下奇怪消息:

I have recently tried implementing memcached for session saving in php. I modified the session.save_handler in my php.ini and for the most part it works correctly. Sessions are saved in it. However, once in a while, I get this weird message for certain sessions:

PHP警告:未知:无法写入会话数据(memcached).请在第0行的未知"中验证session.save_path的当前设置正确(x.x.x.x:11211).

PHP Warning: Unknown: Failed to write session data (memcached). Please verify that the current setting of session.save_path is correct (x.x.x.x:11211) in Unknown on line 0.

会话数据是相同的，但在1MB的内存缓存之下，我还没有看到此消息的出现模式……也许每分钟几次.该网站通常处于中等负载，并发150个用户.

The session data is the same, way under the 1MB barrier of memcached and I have yet to see a pattern in the occurences of this message... maybe a couple of times every minute. The website is usually under medium load, 150 users concurrently.

推荐答案

如果您使用的是内存缓存，则save_path必须具有tcp://前缀.

If you are using memcache then save_path must have the tcp:// prefix.

如果您使用的是 memcached ，则save_path不应具有tcp://前缀.

If you are using memcached then the save_path should not have the tcp:// prefix.
