The server quit without updating PID file (/var/lib/mysql/i[FAILED]0cdei5171kqskZ.pid).

解决:(我们确实是没有/var/log/mariadb/mariadb.log 这个目录，这个是因为你没有指定他的配置文件的话，他会默认找到/etc/my.cnf 这个配置文件，因为我们修改了mysql的数据存储目录)

rm -f /etc/my.cnf

4.

[root@iZ2zeg11g0cdei5171kqskZ mysql]# mysql -uroot -p
-bash: mysql: command not found

解决:(这个是因为/usr/local/bin目录下缺失mysql导致，只需要一下方法建立软链接，即可以解决)

 ln -s /usr/local/mysql/bin/mysql /usr/local/bin/mysql
