# 六、其他
# 1.更改数据存储路径
新建路径 mkdir /work/mysql/data/
vi /etc/mysql/mysql.conf.d/mysqld.cnf
1.修改其中的datadir
2.添加新路径的权限
sudo vi /etc/apparmor.d/local/usr.sbin.mysqld
添加以下内容，替换/work/mysql/data/为新的数据目录路径：
/work/mysql/data/ r,
/work/mysql/data/** rwk,
重新加载AppArmor配置：
sudo apparmor_parser -r /etc/apparmor.d/usr.sbin.mysqld
