錯誤資訊：
[ERROR] /usr/sbin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2 - No such file or directory)
2018-10-16T12:58:13.166990Z 0 [ERROR] Can't start server: can't create PID file: No such file or directory
解決方案：
1、檢視是否存在mysqld 執行目錄
到/var/run目錄下檢視：
[ [email protected] mysql]# cd /var/run
[[email protected] run]# ls -l mysqld*
ls: mysqld*: No such file or directory
2、如果目錄不存在，就建立
mkdir /var/run/mysqld
3、給新建的mysqld目錄授權
chown mysql:mysql /var/run/mysqld -R
4、重啟mysql服務
systemctl restart mysqld
