更改MySQL目录

   MySQL默认的数据文件存储目录为/var/lib/mysql。假如要把目录移到/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:

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

   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:

   vi  my.cnf    (用vi工具编辑my.cnf文件,,找到下列数据修改之)

   # The MySQL server

    [mysqld]

    port   = 3306

    #socket  = /var/lib/mysql/mysql.sock(原内容,为了更稳妥用“#”注释此行)

    socket  = /home/data/mysql/mysql.sock   (加上此行)

   6、修改MySQL启动脚本/etc/rc.d/init.d/mysql

   最后,需要修改MySQL启动脚本/etc/rc.d/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。

   [root@test1 etc]# vi /etc/rc.d/init.d/mysql

   #datadir=/var/lib/mysql    (注释此行)

   datadir=/home/data/mysql   (加上此行)

   7、重新启动MySQL服务

   /etc/rc.d/init.d/mysql start

   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。
