2021 CentOS 6.8 安装 MySQL 5.6

1. 配置Yum阿里云源

由于CentOS 官方放弃了对CentOS6.x的维护和更新 下架了所有的更新和包

1. 备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2. 获取阿里云 CentOS 6 源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo

3. 非阿里云服务器配置

sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

sed -i  's/http/https/g' /etc/yum.repos.d/CentOS-Base.repo

4. 调整版本配置

sed -i  's/$releasever/6.8/g' /etc/yum.repos.d/CentOS-Base.repo

sed -i  's/centos/centos-vault/g' /etc/yum.repos.d/CentOS-Base.repo

5. 清除缓存和更新缓存

yum clean all && yum makecache
