yum安装mysql5.7报密钥已过期的解决方案

Posted 2022-03-12 江南独孤客

一、安装YUM Repo
1、由于CentOS 的yum源中没有mysql，需要到mysql的官网下载yum repo配置文件。
下载命令：

wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm

2、然后进行repo的安装：
rpm -ivh mysql57-community-release-el7-9.noarch.rpm

执行完成后会在/etc/yum.repos.d/目录下生成两个repo文件mysql-community.repo mysql-community-source.repo
3.1、安装命令：
yum install mysql-server
报错如一下：
[root@dbos-bigdata-test007 yum.repos.d]# yum install mysql-server
