Linux下启动MySQL提示“mysql deamon failed to start”错误的解决办法

# /etc/init.d/mysqld start
MySQL Daemon failed to start.
Starting mysqld: [FAILED]
查看mysqld的log文件
#less /var/log/mysqld.log
/usr/libexec/mysqld: Can't change dir to ‘XXX’ (Errcode: 13)
首先是查看数据库日志

mysqld started
[WARNING] CAN'T CREATE TEST FILE XXX.LOWER-TEST
[WARNING] CAN'T CREATE TEST FILE XXX.LOWER-TEST
/USR/LIBEXEC/MYSQLD: CAN'T CHANGE DIR TO '/XXX' (ERRCODE: 13)
