• 说明，本次安装是基于centos7 用rpm包安装

1，设置yum 源

cat   >>  /etc/yum.repos.d/MariaDB.repo  << EOF
[mariadb]
name= MariaDB
baseurl = https://mirrors.nju.edu.cn/mariadb/yum/10.5/centos7-amd64 
gpgkey = https://mirrors.nju.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck = 1
EOF

2，验证yum源是否有效同时检查mysql-client可用版本
yum list mariadb-client --showduplicates

3，指定仓库、软件版本下载rpm 包

yum install --enablerepo=mariadb --downloadonly --downloaddir=/henan/mysql MariaDB-client-10.5.15

4，根据情况本机安装或是移到其它机器上进行安装

 yum   -y localinstall *.rpm

5，进行登录验证
which mysql
mysql -h [hostname/ip] -u [username] -P [3306] -p
