一、準備工作

https://mariadb.org/mariadb/all-releases/

選擇想要安裝的版本，再選擇MariaDB Respositories，複製yum源資訊

二、先確認當前環境是否安裝過資料庫

[root@localhost ~]# rpm -q mariadb-server
package mariadb-server is not installed

三、重新配置yum倉庫

# vim /etc/yum.repos.d/MariaDB.repo

　　將複製的yum源資訊填寫到MariaDB.repo

[mariadb]
name = MariaDB
baseurl 
 
= https://tw1.mirror.blendbyte.net/mariadb/yum/10.6/centos7-amd64
gpgkey=https://tw1.mirror.blendbyte.net/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1

　　檢視已安裝好的yum源倉庫

[root@localhost yum.repos.d]# yum repolist

四、yum安裝mariadb服務端

# yum install -y mariadb-server

[root@localhost yum.repos.d]# mariadb --version
mariadb  Ver 15.1 Distrib 10.6.4-MariaDB, for Linux (x86_64) using readline 5.1

五、安裝後，執行安全加固(過程略)
