CentOS Linux更改MySQL數據庫目錄位置

2019-05-27 06:39:26 9842

有時(shí)候我們需要更改mysql數據文件的所在位置，下面以yum安裝的mysql為例,把默認的data目錄/var/lib/mysql更改為/home/mysql。

停止mysqld: service mysqld stop
修改my.cnf 在[mysqld]中，把datadir=/var/lib/mysql更改為datadir=/home/mysql，把socket=/var/lib/mysql.sock更改為socket=/home/mysql/mysql.sock，最終修改如下：
```
[mysqld]
datadir=/home/mysql
socket=/home/mysql/mysql.sock
```
同時(shí)my.cnf添加如下代碼
```
[client]
port = 3306
socket = /home/mysql/mysql.sock
```
移動(dòng)data目錄: mv /var/lib/mysql /home
修改啟動(dòng)文件: vi /etc/init.d/mysqld 把get_mysql_option mysqld datadir “/var/lib/mysql”更改為get_mysql_option mysqld datadir “/home/mysql”。
