Centos7 移动mysql5.7.19 数据存储位置的操作方法

cp -a /usr/local/mysql/data/ /home/mysqldata/

-a ：相当于 -pdr 的意思（参数pdr分别为：保留权限，复制软链接本身，递归复制）；

3 . 修改配置文件my.cnf

... 
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 
basedir     = /usr/local/mysql 
#datadir     = /usr/local/mysql/data 
datadir     = /home/mysqldata/data 
#log-error    = /usr/local/mysql/data/mysql_error.log 
log-error    = /home/mysqldata/data/mysql_error.log 
#pid-file    = /usr/local/mysql/data/mysql.pid 
pid-file    = /home/mysqldata/data/mysql.pid 
 
#socket     =/usr/local/mysql/data/mysql.sock 
socket     =/tmp/mysql.sock 
port=3701 
...

4. 启动mysql服务

service mysqld stop
