環境centos6.5  mysql版本是5.5.10

開啟mysql服務

/etc/init.d/mysqld start

報錯如下：Starting MySQL.The server quit without updating PID file (/[FAILED]ql/cc.pid).

我的錯誤日誌是/data/mysql/cc.err：

160418 09:33:10 mysqld_safe Starting mysqld daemon with databases from /data/mysql
160418  9:33:10 InnoDB: The InnoDB memory heap is disabled

160418 09:33:10 mysqld_safe mysqld from pid file /data/mysql/cc.pid ended

我注意到了這個情況：/tmp這個臨時檔案目錄下不能寫檔案看來是許可權配置錯誤了

/usr/local/mysql/bin/mysqld: Can't create/write to file '/tmp/iblXxbUK' (Errcode: 13)

果然錯誤了：

[root@cc /]# ls -ld  /tmp
drwxrwxr-x. 4 root root 4096 Apr 18 09:37 /tmp

修改：[root@cc /]# chmod  1777  /tmp

重新啟動mysql：[root@cc /]# /etc/init.d/mysqld start
Starting MySQL..                                           [  OK  ]
