- These instructions are intended for upgrading from MariaDB 5.5 to MariaDB 10.0 on CentOS 7.
- I’ll be working from a Liquid Web Core Managed CentOS 7 server, and I’ll be logged in as root.
Step #1: Add the MariaDB RepositoryFirst, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new:
yum -y updateNow find which repo you should use with the MariaDB repository generator. We’re going to add the CentOS 7 (64 bit) MariaDB 10.0 repository. For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor
vim /etc/yum.repos.d/MariaDB10.repo# MariaDB 10.0 CentOS repository list – created 2014-10-13 13:04 UTC # http://mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.0/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1 Then exit and save the file with the command :wq .
Step #2: Remove the Existing MariaDB Installation
Be sure to backup MariaDB and/or your entire server before proceeding with the following instructions!
Removing MariaDB will remove services that depend on MariaDB!Stop MariaDB:
systemctl stop mariadbRemove the existing MariaDB packages:
yum remove mariadb-server mariadb mariadb-libsClean-up the repository cache information with the following command:
yum clean all
Step #3: Install MariaDB 10.0At this point, installing MariaDB 10.0 is as simple as running just one command:
yum -y install MariaDB-server MariaDB-clientAnd then start MariaDB again:
systemctl start mysqlBe sure that MariaDB is set to start at boot:
systemctl enable mysqlRun mysql_upgrade:
mysql_upgradeVerify MySQL is now MariaDB by using the command client:
