Editor to share with you how to modify the mysql5.7 data storage directory under Ubuntu18.04, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. Create an additional directory stored by MySQL

Mkdir / database/mysql chmod 700 / database/mysql chown-R mysql:mysq / database/mysql

two。 Copy the previous database to the new storage directory (this avoids re-initialization and the data is still there)

Cp-R / var/lib/mysql/* / database/mysql

3. Delete the log (if you do not delete, you may report an error)

Rm-rf / database/mysql/ib_logfile0 rm-rf / database/mysql/ib_logfile1

4. Modify mysql configuration

Vim / etc/mysql/mysql.conf.d/mysqld.cnf # modify datadir=/var/lib/mysql to the directory you need to modify here is datadir=/database/mysql

5. Modify the configuration file use.sbin.mysqld of apparmor (Ubuntu needs to be modified, CentOS does not)

Vim / etc/apparmor/usr.sbin.mysqld

Set

/ var/lib/mysql/ r, / var/lib/mysql/** rwk

Modify to

/ database/mysql/ r, / database/mysql/** rwk

Configure and restart 6.reload apparmor

Service apparmor reload service apparmor restart

7. Restart mysql
