description |
After upgrading to 15.04 mysql cannot set the file limit and so it doesn't work well.
/var/log/mysql/error.log shows the following:
[Warning] Buffered warning: Changed limits: max_open_files: 1024 (requested 5000)
[Warning] Buffered warning: Changed limits: table_cache: 431 (requested 2000)
[ERROR] /usr/sbin/mysqld: Can't open file: ... (errno: 24 - Too many open files)
The issue looks to be related to the recent switch to systemd indeed if I start using upstart everything work fine.
I found out similar issues reported on Debian and the general suggestion is to add following line to the `mysqld.service` anyway this file is not present on my installation :
LimitNOFILE=infinity
LimitMEMLOCK=infinity

Other distro stores this file in `/usr/lib/systemd/system/mysqld.service`
I'm not sure how Ubuntu is managing this, maybe with file in dir /etc/default/ ?
I have also tried adding following lines in /etc/security/limits.conf, but the problem persist:
mysql soft nofile 65535
mysql hard nofile 65535
