MySQL默认的数据文件存储目录为/var/lib/mysql。假如要把MySQL目录移到/home/data下需要进行下面几步: 1、home目录下建立data目录 cd /home mkdir data 2、把MySQL服务进程停掉 mysqladmin -u root -p shutdown 3、把/var/lib/mysql整个目录移到/home/data

MySQL默认的数据文件存储目录为/var/lib/mysql。假如要把MySQL目录移到/home/data下需要进行下面几步:

1、home目录下建立data目录

cd /home

mkdir data

2、把MySQL服务进程停掉

mysqladmin -u root -p shutdown

3、把/var/lib/mysql整个目录移到/home/data

mv /var/lib/mysql /home/data/

这样就把MySQL的数据文件移动到了/home/data/mysql下。

4、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。命令如下:

1

[root@test1 mysql]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

Copy after login

5、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。操作如下:

1

vi  my.cnf  (用vi工具编辑my.cnf文件,找到下列数据修改之)<br># The MySQL server<br>[mysqld]<br>port = 3306<br>#socket  = /var/lib/mysql/mysql.sock(原内容,为了更稳妥用“#”注释此行)<br>socket  = /home/data/mysql/mysql.sock (加上此行)

Copy after login

6、修改MySQL启动脚本/etc/init.d/mysql

最后,需要修改MySQL启动脚本/etc/init.d/mysql,把其中datadir=/var/lib/mysql一行中,等号右边的路径改成你现在的实际存放路径:home/data/mysql。

1

[root@test1 etc]# vi /etc/init.d/mysql<br>#datadir=/var/lib/mysql(注释此行)<br>datadir=/home/data/mysql (加上此行)

Copy after login

7、重新启动MySQL服务

1

/etc/init.d/mysql start

Copy after login

或用reboot命令重启Linux

如果工作正常移动就成功了,否则对照前面的7步再检查一下。

还要注意目录的属主和权限。
