Linux下启动MySQL提示“mysql deamon failed to start”错误的解决办法
网站突然连接不上数据库,于是朋友直接重启了一下服务器。进到cli模式下,执行 service myqsld start 发现还是提示mysql deamon
有台Linux服务器,,系统为CentOS系统.
描述:
网站突然连接不上数据库,于是朋友直接重启了一下服务器。进到cli模式下,执行 service myqsld start 发现还是提示"mysql deamon failed to start"错误信息.
# /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)
[ERROR] Aborting
首先检查数据目录和日志目录的权限和所属用户,权限和所属用户都没问题,那应该是SELINUX的权限限制了。
先查看当前配置信息.
# getenforce
Enforcing
就表明SELinux已经启用.只需要关闭即可。
关闭方法:
#setenforce 0 (0|1 开|关)
或者
setsebool ftpd_disable_trans 1
命令也可以.
