Hi list. I'm new with archlinux and especially systemd. I'm using linux since around twenty years, so i'm not realy newbie but... I have many questions but I'll ask one by one. I read wiki about systemctl and I'm not sure to have understood everything :-( For instance, to have a daemon at boottime, I have tried : systemctl enable --now ... It seems to be OK with ntp, fcron and NetworkManager. But with mariadb I obtain a failure. Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xeu mariadb.service" for details. I tried systemctl status mariadb and obtained × mariadb.service - MariaDB 10.6.4 database server Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2021-11-08 18:03:16 CET; 1min 47s ago Docs: man:mariadbd(8) https://mariadb.com/kb/en/library/systemd/ Process: 515 ExecStartPre=/bin/sh -c systemctl unset-environment _WSREP_START_POSITION (code=exited, status=0/SUCCESS) Process: 516 ExecStartPre=/bin/sh -c [ ! -e /usr/bin/galera_recovery ] && VAR= || VAR=`cd /usr/bin/..; /usr/bin/galera_recovery`; [ $? -eq 0 ] && systemctl set-environment _WSREP_START_POSITION=$VAR || exit 1 (code=exited, status=0/SUCCESS) Process: 524 ExecStart=/usr/bin/mariadbd $MYSQLD_OPTS $_WSREP_NEW_CLUSTER $_WSREP_START_POSITION (code=exited, status=1/FAILURE) Main PID: 524 (code=exited, status=1/FAILURE) Status: "MariaDB server is down" CPU: 95ms nov. 08 18:03:15 messier31 mariadbd[524]: 2021-11-08 18:03:15 0 [Note] InnoDB: Buffer pool(s) load completed at 211108 18:03:15 nov. 08 18:03:15 messier31 mariadbd[524]: 2021-11-08 18:03:15 0 [ERROR] Can't open and lock privilege tables: Table 'mysql.servers' doesn't exist nov. 08 18:03:15 messier31 mariadbd[524]: 2021-11-08 18:03:15 0 [Note] Server socket created on IP: '0.0.0.0'. nov. 08 18:03:15 messier31 mariadbd[524]: 2021-11-08 18:03:15 0 [Note] Server socket created on IP: '::'. nov. 08 18:03:15 messier31 mariadbd[524]: 2021-11-08 18:03:15 0 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.db' doesn't exist nov. 08 18:03:15 messier31 mariadbd[524]: 2021-11-08 18:03:15 0 [ERROR] Aborting nov. 08 18:03:16 messier31 mariadbd[524]: Warning: Memory not freed: 280 nov. 08 18:03:16 messier31 systemd[1]: mariadb.service: Main process exited, code=exited, status=1/FAILURE nov. 08 18:03:16 messier31 systemd[1]: mariadb.service: Failed with result 'exit-code'. nov. 08 18:03:16 messier31 systemd[1]: Failed to start MariaDB 10.6.4 database server. Those messages don't help me. Can someone tell me more ? Regards. -- Philippe
