Question

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         


        

Answer 1

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/
