2.1、mysql8:
yum默认直接安装最新版本。
yum -y install mysql-server
2.2、mysql5.7:
wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
查看mysql157的rpm包文件
rpm -qpl mysql57-community-release-el7-7.noarch.rpm
警告：mysql57-community-release-el7-7.noarch.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1f5: NOKEY
/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
/etc/yum.repos.d/mysql-community-source.repo
/etc/yum.repos.d/mysql-community.repo
安装rpm包
rpm -ivh mysql57-community-release-el7-7.noarch.rpm
