mariadb遇到Cannot change ownership of the database directories to the

修改了 /etc/my.cnf 将datadir改了，datadir=/data/mysql

无法启动，报错：

Mar 14 13:59:29 localhost.localdomain mariadb-prepare-db-dir[10433]: Cannot change ownership of the database directories to the 'mysql'

Mar 14 13:59:29 localhost.localdomain mariadb-prepare-db-dir[10433]: user.  Check that you have the necessary permissions and try again.

Mar 14 13:59:29 localhost.localdomain mariadb-prepare-db-dir[10433]: Initialization of MariaDB database failed.

Mar 14 13:59:29 localhost.localdomain mariadb-prepare-db-dir[10433]: Perhaps @sysconfdir@/my.cnf is misconfigured or there is some problem with permissions of /data/mysql.

 

 

是由于/data/mysql的文件拥有者导致的，修改所有者重启：

 

chown -R mysql:mysql /data/mysql
