Why doesn't table_cache change in MariaDB?

Question

MySQL

Good afternoon, there is a bunch:
PHP Version 5.4.16 + Apache / 2.4.6 + 5.5.37-MariaDB + nginx 1.6
Above the base, of course, like all ordinary users, phpmyadmin v.4.2.7.1 hangs
and all this is spinning on CentOS 7.
The problem is that the tuner decided to scan Maria and received in response that my table_open_cache is too small.
I laughed, because I completely re-uploaded the config (my.cnf) and specified table_open_cache = 4096 in it, which is quite enough for my 3K tables.
BUT, as it turned out, it did not change and defaulted to 407.
What could be the problem?
Maria's logs say:
140917 13:10:32 mysqld_safe mysqld from pid file /var/run/mariadb/mariadb.pid ended
140917 13:10:32 mysqld_safe Starting mysqld daemon with databases from /var/lib/
mysql

Answer 1

mysql cannot set a limit greater than the system limit on open files
, you can see it ulimit -n
increase - ulimit -n 4096
