Okay, I suppose we can change that and start accepting connections before reporting "ready"... > in fact systemd calls "ExecStart" and get the zero-return-value from > "/usr/libexec/mysqld" *before* the service really accepts connections > that's why "/usr/libexec/mysqld-wait-ready" was needed This is something I don't understand. As far as I remember, /usr/libexec/mysqld does not return until you shutdown the server. It doesn't daemonize itself, the caller is supposed to start it in the background. Perhaps - just guessing - systemd looks for a PIDFile and assumes that the service is ready as soon as the PIDFile is created? > ________________________________ > [Service] > Type=simple > PIDFile=/var/run/mysqld/mysqld.pid > ExecStart=/usr/libexec/mysqld --defaults-file=/etc/my.cnf > --pid-file=/var/run/mysqld/mysqld.pid > --socket=/var/lib/mysql/mysql.sock --open-files-limit=750000 --basedir=/usr > --user=mysql > ExecStartPost=/usr/libexec/mysqld-wait-ready $MAINPID > ________________________________ Regards, Sergei _______________________________________________ Mailing list: https://launchpad.net/~maria-discuss Post to : [email protected] Unsubscribe : https://launchpad.net/~maria-discuss More help : https://help.launchpad.net/ListHelp
