我删除了/usr/lib/mysql，/etc/mysql删除了mariadb，并使用yaourt -Rsn maraidb卸载了mariadb服务器。
mariadb（mysqld）因重新安装mariadb导致丢失一些文件而失败。 日志是：
[ERROR] Could not open mysql.plugin table. Some plugins may be not loaded
[Note] Recovering after a crash using mysql-bin
[Note] Starting crash recovery...
[Note] Crash recovery finished.
[Warning] Failed to load slave replication state from table
mysql.gtid_slave_pos: 1146: Table 'mysql.gtid_slave_pos>
[ERROR] Can't open and lock privilege tables: Table 'mysql.servers'
doesn't exist
[Note] Server socket created on IP: '::'.
[ERROR] Fatal error: Can't open and lock privilege tables: Table
'mysql.user' doesn't exist
似乎mariadb没有成功初始化，但我无法弄清楚如何修复它。 谁能帮我？非常感谢。
答案 0 :(得分：0)
安装后注意：
您需要在启动服务之前初始化MariaDB数据目录。这可以使用mysql_install_db命令完成，例如：
