安装后,我运行systemctl enable mysqld.service
。然后,输出是:
Failed to execute operation: Too many levels of symbolic links
出现此错误后,我重新启动服务,并检查 mysqld.service 的状态。systemctl status mysqld.service -l
输出为
● mariadb.service - MariaDB database server

删除mysqld.service
符号链接/etc/systemd/system
并再次启用mysqld.service
:
rm /etc/systemd/system/mysqld.service
systemctl enable mysqld.service
