mariadb 실행시 Failed to issue method call: No such file or directory. 오류 발생.

systemctl start mariadb 실행시 아래와 같은 오류 발생.
Failed to issue method call: No such file or directory.

아래와 같이 /usr/lib/systemd/system/mariadb.service의
소프트 링크가 /etc/systemd/system/multi-user.target.wants/mariadb.service 위치에
있어야 하나, 해당 파일이 없음.

-bash-4.2# systemctl status mariadb
mariadb.service - MariaDB database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; disabled)
   Active: inactive (dead)

확인 결과 mariadb 가 disable 되어 있음.

 

아래 명령 실행으로 생성.

-bash-4.2# systemctl enable mariadb
ln -s '/usr/lib/systemd/system/mariadb.service' '/etc/systemd/system/multi-user.target.wants/mariadb.service'

 

enable 후 다시 확인.

-bash-4.2# systemctl status mariadb
mariadb.service - MariaDB database server
Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled)
Active: inactive (dead)

위와 같이 나오는 데, 원인은 systemctl 으로  mariadb를 실행하지 않아서임.
/etc/init.d/mysqld start << 이 명령어로 실행 되고 있음.

/etc/init.d/mysqld stop 으로 mysql shutdown 후
systemctl start mariadb 실행. 에러 없이 실행됨.

 

확인.

-bash-4.2# systemctl status mariadb
mariadb.service - MariaDB database server
