解决方案

Redis 永远不会改变最大打开文件数.

这是一个操作系统配置，也可以按用户进行配置.该错误是描述性的，并告诉您:增加 'ulimit -n'"

您可以参考这篇博文了解如何增加最大打开文件描述符:http://www.cyberciti.biz/常见问题解答/linux-increase-the-maximum-number-of-open-files/

1167:M 26 Apr 13:00:34.666 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.
1167:M 26 Apr 13:00:34.667 # Redis can't set maximum open files to 10032 because of OS error: Operation not permitted.
1167:M 26 Apr 13:00:34.667 # Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.

解决方案

Redis will never change the maximum open files.

This is a OS configuration and it can be configured on a per user basis also. The error is descriptive and tells you: "increase 'ulimit -n'"

You can refer to this blog post on how to increase the maximum open files descriptors: http://www.cyberciti.biz/faq/linux-increase-the-maximum-number-of-open-files/
