A MySQL or MariaDB server package (MariaDB-server-10.1.31-1.el7.centos.x86_64) is installed.
|
|
Upgrading directly from MySQL 10.1 to MariaDB 10.2 may not
|
be safe in all cases. A manual dump and restore using mysqldump is
|
recommended. It is important to review the MariaDB manual's Upgrading
|
section for version-specific incompatibilities.
|
|
A manual upgrade is required.
|
|
- Ensure that you have a complete, working backup of your data and my.cnf
|
files
|
- Shut down the MySQL server cleanly
|
- Remove the existing MySQL packages. Usually this command will
|
list the packages you should remove:
|
rpm -qa | grep -i '^mysql-'
