很多时候，mysql的数据会非常大，数据默认放在/var/lib/mysql，由于/var所划分的空间不够大，所以我们需要将mysql数据存放路径修改一下，放到大分区里面，以便可以应付mysql数据增长。

 

1.设置新的存放路径 

mkdir -p /data/mysql

 

2.复制原有数据 

cp -R /var/lib/mysql/* /data/mysql

 

3.修改权限 

chown -R mysql:mysql /data/mysql

 

4.修改配置文件 

vim /etc/mysql/my.cnf
datadir         = /data/mysql

 

5.修改启动文件 

vim /etc/apparmor.d/usr.sbin.mysqld
#把
/var/lib/mysql r,
/var/lib/mysql/** rwk, 

#改成
/data/mysql r,
/data/mysql/** rwk,

 

6.重启服务

重启apparmor 

/etc/init.d/apparmor restart
/etc/init.d/mysql restart

 

完成
