Pessoal, bom dia! Me dá uma ajuda! Tive que alterar a partição de dados do meu MySQL pois a partição "/" estava estourando. Fiz o seguinte procedimento: - Parei o MySQL - Copiei toda a base da origem para o destino - Dei as permissões para o usuário "mysql" do linux - Alterei o parâmetro "datadir" do my.cnf - Tentei inicializar o MySQL. Está dando erro para inicializar: root@RJMRLNX01:~# service mysql start Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details. root@RJMRLNX01:~# systemctl status mysql.service ● mysql.service - MySQL Community Server Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled) Active: inactive (dead) (Result: exit-code) since seg 2016-09-12 10:10:16 BRT; 491ms ago Process: 50336 ExecStart=/usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid (code=exited, status=1/FAILURE) Process: 50328 ExecStartPre=/usr/share/mysql/mysql-systemd-start pre (code=exited, status=0/SUCCESS) Main PID: 56049 (code=exited, status=0/SUCCESS) set 12 10:10:16 RJMRLNX01 systemd[1]: Failed to start MySQL Community Server. set 12 10:10:16 RJMRLNX01 systemd[1]: mysql.service: Unit entered failed state. set 12 10:10:16 RJMRLNX01 systemd[1]: mysql.service: Failed with result 'exit-code'. set 12 10:10:16 RJMRLNX01 systemd[1]: mysql.service: Service hold-off time over, scheduling restart. set 12 10:10:16 RJMRLNX01 systemd[1]: Stopped MySQL Community Server. set 12 10:10:16 RJMRLNX01 systemd[1]: mysql.service: Start request repeated too quickly. set 12 10:10:16 RJMRLNX01 systemd[1]: Failed to start MySQL Community Server. root@RJMRLNX01:/etc/mysql/mysql.conf.d# journalctl -xe -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- A unidade mysql.service falhou. -- -- O resultado é failed. set 12 11:07:32 RJMRLNX01 systemd[1]: mysql.service: Unit entered failed state. set 12 11:07:32 RJMRLNX01 systemd[1]: mysql.service: Failed with result 'exit-code'. set 12 11:07:32 RJMRLNX01 systemd[1]: mysql.service: Service hold-off time over, scheduling restart. set 12 11:07:32 RJMRLNX01 systemd[1]: Stopped MySQL Community Server. -- Subject: A unidade mysql.service concluiu o desligamento -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- A unidade mysql.service concluiu o desligamento. set 12 11:07:32 RJMRLNX01 systemd[1]: Starting MySQL Community Server... -- Subject: Unidade mysql.service sendo iniciado -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- A unidade mysql.service está sendo iniciada. set 12 11:07:32 RJMRLNX01 audit[4360]: AVC apparmor="STATUS" operation="profile_replace" profile="unconfined" name="/usr/sbin/mysqld" pid=4360 comm="apparmor set 12 11:07:32 RJMRLNX01 kernel: audit: type=1400 audit(1473689252.755:98): apparmor="STATUS" operation="profile_replace" profile="unconfined" name="/usr/sb set 12 11:07:32 RJMRLNX01 mysqld[4363]: Initialization of mysqld failed: 0 set 12 11:07:32 RJMRLNX01 systemd[1]: mysql.service: Control process exited, code=exited status=1 set 12 11:07:32 RJMRLNX01 systemd[1]: Failed to start MySQL Community Server. -- Subject: A unidade mysql.service falhou -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- A unidade mysql.service falhou. -- -- O resultado é failed. set 12 11:07:32 RJMRLNX01 systemd[1]: mysql.service: Unit entered failed state. set 12 11:07:32 RJMRLNX01 systemd[1]: mysql.service: Failed with result 'exit-code'. set 12 11:07:33 RJMRLNX01 systemd[1]: mysql.service: Service hold-off time over, scheduling restart. set 12 11:07:33 RJMRLNX01 systemd[1]: Stopped MySQL Community Server. -- Subject: A unidade mysql.service concluiu o desligamento -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- A unidade mysql.service concluiu o desligamento. set 12 11:07:33 RJMRLNX01 systemd[1]: mysql.service: Start request repeated too quickly. set 12 11:07:33 RJMRLNX01 systemd[1]: Failed to start MySQL Community Server. -- Subject: A unidade mysql.service falhou -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- A unidade mysql.service falhou. -- -- O resultado é failed. set 12 11:09:01 RJMRLNX01 CRON[4372]: pam_unix(cron:session): session opened for user root by (uid=0) set 12 11:09:01 RJMRLNX01 CRON[4371]: pam_unix(cron:session): session opened for user root by (uid=0) set 12 11:09:01 RJMRLNX01 CRON[4373]: (root) CMD ( [ -x /usr/lib/php/sessionclean ] && /usr/lib/php/sessionclean) set 12 11:09:01 RJMRLNX01 CRON[4374]: (root) CMD ( [ -x /usr/lib/php5/sessionclean ] && /usr/lib/php5/sessionclean) set 12 11:09:01 RJMRLNX01 CRON[4371]: pam_unix(cron:session): session closed for user root set 12 11:09:01 RJMRLNX01 CRON[4372]: (CRON) info (No MTA installed, discarding output) set 12 11:09:01 RJMRLNX01 CRON[4372]: pam_unix(cron:session): session closed for user root O que fiz de errado?
