增加软件源
/etc/yum.repos.d/MariaDB.repo
配置文件示例如下，可根据YUM源目录中版本及系统进行修改
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
配置路径
执行安装
yum install MariaDB-server MariaDB-client
使用PuTTY Key Generator生成SSH密钥对，并将私钥保存为.ppk文件
查看当前用户目录，建立ssh密钥存储目录
建立公钥认证存储文件，并复制PuTTY Keygen生成的公钥
[root@localhost ~]# vi .ssh/authorized_keys
修改密钥存储目录和文件的属性为600
确保系统SELinux已关闭
使用Putty登录系统，输入服务器IP地址
修改SSH认证类型设置，选择已保存的私钥文件后点击Open开始连接
提示输入用户名
成功登录进入系统，并显示采用注释为公钥进行认证
