[root@spark01 ~]# /etc/init.d/mysqld start


starting mysqld (via systemctl):  job for mysqld.service failed because the control process exited with error code. see "systemctl status mysqld.service" and "journalctl -xe" for details.

建立/var/run/mysqld/目錄，重啟mysql服務

[root@spark01 ~]# mkdir -p /var/run/mysqld/

[root@spark01 ~]# /etc/init.d/mysqld start

依舊報錯，重新檢視告警日誌，有以下輸出

2016-01-20t10:28:37.183387z 0 [error] /usr/sbin/mysqld: can't create/write to file '/var/run/mysqld/mysqld.pid' (errcode: 13 - permission denied)


2016-01-20t10:28:37.183431z 0 [error] can't start server: can't create pid file: permission denied

160120 18:32:06 mysqld_safe starting mysqld daemon with databases from /var/lib/mysql
原來，/var/run/mysqld/的屬主和屬組還是root，mysql並不能在其中建立檔案，後修改該目錄的屬主和屬組，啟動ok。

[root@spark01 ~]# ls -ld /var/run/mysqld/


drwxr-xr-x 2 root root 40 jan 20 18:28 /var/run/mysqld/


[root@spark01 ~]# chown mysql.mysql /var/run/mysqld/


[root@spark01 ~]# /etc/init.d/mysqld start


starting mysqld (via systemctl):                           [  ok  ]
