centos7.9 mysql 目录迁移注意事项

一、停止mysql服务

systemctl start mysqld

 

二、先复制原来的文件夹,确定正常启动后,再删除旧文件夹

cp -rf /var/lib/mysql /home/data/mysql

 

修改vi /etc/my.cnf

datadir=/home/data/mysql
socket=/home/data/mysql/mysql.sock

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

 

1、权限问题

Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

解决方法

修改selinux状态

getenforce     (查看selinux状态)

setenforce 0 (临时关闭)
vi /etc/selinux/config
getenforce

 

修改目录权限

chmod -R a+rwx /home/data/mysql
