Local socket access to MariaDB does not work anymore after update to version 10.0.30

After a maintenance update of MariaDB to version 10.0.30 build 25.1 a connection to the database via local (AF_UNIX) sockets is not possible anymore.


This issue has been fixed with build 28.1 of MariaDB 10.0.30:
As a quick workaround, manually setting the correct permissions of /var/run/mysql and restarting MariaDB restores connectivity:

chmod 755 /var/run/mysql
systemctl restart mysql

This needs to be done after every reboot as /var/run is a symlink to /run which is located on a ramdisk.


The MariaDB start script was hardened to reduce the default permissions of created files to the minimum. Due to an oversight, the script does not set the correct permissions for /var/run/mysql after it creates the directory. Subsequently, MariaDB cannot create its socket when it runs as a user other than root.
