centos7系统安装mysql，解决各种依赖问题

centos7系统安装mysql数据库及解决我遇到的各种依赖问题

• 下载

https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar
建议用迅雷下载，比较快

• 清除本机所有安装过的mysql和mariadb数据库

用下边的命令查询安装的mysql和mariadb

rpm -qa|grep mysql 
和
rpm -qa|grep mariadb

用下边的命令删除所有列出的内容

rpm -e xxx
或
yum remove xxx

• 解压安装

tar -xvf mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar

按顺序安装，不按顺序安装会有依赖问题

rpm -ivh mysql-community-common-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-embedded-compat-8.0.18-1.el7.x86_64.rpm

安装mysql-community-devel-8.0.18-1.el7.x86_64.rpm如果报错
