selinux vs searchd

If, like me, you use searchd and mysql then selinux will provoke the following message:

ERROR 1429 (HY000): Unable to connect to foreign data source: failed to connect to searchd (host=127.0.0.1, errno=13, port=931

The solution is simple:

semanage port -a -t mysqld_port_t -p tcp 9312
