centos7通过yum源安装制定版本的mariadb数据库

一、准备工作

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

选择想要安装的版本，再选择MariaDB Respositories，复制yum源信息

二、先确认当前环境是否安装过数据库 

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

三、重新配置yum仓库

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

　　将复制的yum源信息填写到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

　　查看已安装好的yum源仓库

[root@localhost yum.repos.d]# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
base | 3.6 kB 00:00:00
epel | 4.7 kB 00:00:00
extras | 2.9 kB 00:00:00
mariadb | 3.4 kB 00:00:00
updates | 2.9 kB 00:00:00

repo id repo name status
base/7/x86_64 CentOS-7 10,072
epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 13,674
extras/7/x86_64 CentOS-7 500
mariadb MariaDB 93
updates/7/x86_64 CentOS-7 2,943
repolist: 27,282

四、yum安装mariadb服务端

# 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、安装后，运行安全加固(过程略)
