Package: mariadb-server-10.1 Version: 10.1.23-9+deb9u1 Severity: grave Tags: patch Justification: renders package unusable
Dear Maintainer, After upgrading from Jessie to Stretch I was unable to get my multi-instance mySQL setup working using the installed .service files. I have a machine with 2 mySQl instances running, which in Jessie I managed with mysqld_multi in an init.d script. This is no longer supported with systemd/mariadb in Stretch (only the first instance was started) and so I changed to using the"mariadb@.service" to invoke each instance. Once this was up and running I rebooted and both mySQL instanced failed to start, with: [ERROR] Can't start server : Bind on unix socket: No such file or directory [ERROR] Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ? ..in syslog. On inspection the /var/run/mysqld directory did not exist. I created it and both instances started manually, but after a reboot the same problem persisted. I fixed the problem by copying the line that creates /var/run/mysqld from the single-instance mariadb.service. Diff: @@ -65,6 +65,8 @@ # Execute pre and post scripts as root, otherwise it does it as User= PermissionsStartOnly=true +ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld + The mariadb and mariadb@ services can't both be active at once, so I think this is a serious bug that breaks the ability to run multiple mySQL instances out of the box. I had a few other issues after the upgrade too, I'm not sure if they count as bugs or not because I had a mysqld_multi stule my.cnf (ie with [mysqld1], [mysqld2] sections) so I don't know if they would occur with an existing single-instance install. 1. My main [mysqld] config settings were being overwritten by a 50_server.cnf file in mariadb.conf.d, even after I copied them to a my.cnf file in conf.d. I had to deleted the 50_server.cnf to recreate the server I had on Jessie. And should this file be in mariadb.conf.d anyway when it's got non-mariadb-specific settings like cache sizes etc (I may have caught it sooner if it were in conf.d)? 2. I had to run mysql_upgrade on both databases after the install - should this be automatic?
