# 将 MySQL 服务进程停掉

# 将 /var/lib/mysql 整个目录移到 /home/data
mv /var/lib/mysql /home/data/

# 找到 my.cnf 配置文件
# 如果 /etc/ 目录下没有 my.cnf 配置文件，请到 /usr/share/mysql/ 下找到 *.cnf 文件，拷贝其中一个到 /etc/ 并改名为 my.cnf 中
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

# 编辑 MySQL 的配置文件 /etc/my.cnf
# 为保证 MySQL 能够正常工作，需要指明 mysql.sock 文件的产生位置
# 修改 socket=/var/lib/mysql/mysql.sock 一行中等号右边的值为 /home/mysql/mysql.sock
vi my.cnf
# 省略编辑

# 修改 MySQL 启动脚本 /etc/rc.d/init.d/mysql
# 将其中 datadir=/var/lib/mysql 一行中，等号右边路径改成你现在的实际存放路径：home/data/mysql

# 重新启动 MySQL 服务
