Introduction to MariaDB
MariaDB Server is a general-purpose open source relational database management system. It is one of the most popular database servers in the world, with well-known users including Wikipedia , WordPress.com , and Google . MariaDB Server is released under the GPLv2 open source license and is guaranteed to remain open source.
It can be used for high-availability transactional data, analytics, as an embedded server, and a wide range of tools and applications support MariaDB Server.
mariadb&mysql
The difference between mariadb and mysql is that MariaDB is not just a replacement for Mysql. Mysql has been closed source by Oracle, while mariaDB is open source. MariaDB includes some new features that make it superior to MySQL. MariaDB and MySQL are compatible in most aspects, and for developers, there is almost no difference. Maria DB is a branch version of MySQL using the Aria storage engine, and Mysql is the most popular relational database management system. MySQL is one of the best RDBMS application software in terms of WEB applications. Moreover, MariaDB is the fastest-growing MySQL branch version, and the release speed of new versions has exceeded Oracle's official MySQL version.
System: almalinux9
Background: The current system installed is mariadb that comes with version 10.3.5, which does not meet the needs of installing zabbix, so it needs to be upgraded to 10.9 (just choose a version)
Uninstall the old version of mariadb
dnf remove maria*Step 1: Obtain repo information from the official website
Download MariaDB Server - MariaDB.org
Form repo information according to your own system selection
Create the mariadb.repo file under /etc/yum.repos.d/ and copy the following content into it
# MariaDB 10.9 CentOS repository list - created 2023-06-28 01:28 UTC
# https://mariadb.org/download/
[mariadb]
name = MariaDB
# rpm.mariadb.org is a dynamic mirror if your preferred mirror goes offline. See https://mariadb.org/mirrorbits/ for details.
# baseurl = https://rpm.mariadb.org/10.9/centos/$releasever/$basearch
baseurl = https://tw1.mirror.blendbyte.net/mariadb/yum/10.9/centos/$releasever/$basearch
module_hotfixes = 1
# gpgkey = https://rpm.mariadb.org/RPM-GPG-KEY-MariaDB
gpgkey = https://tw1.mirror.blendbyte.net/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck = 1
The next step is to update the warehouse cache
dnf clean all
dnf makecacheStep 2: Install mariadb
dnf install MariaDB-server MariaDB-client
Make sure the version is correct and install it after it is correct.
[root@localhost yum.repos.d]# dnf install MariaDB-server MariaDB-client
