yum or rpm？

yum安装方式很方便，但是下载mysql的时候从官网下载，速度较慢。

rpm安装方式可以从国内镜像下载mysql的rpm包，比较快。rpm也适合离线安装。

环境说明

• 操作系统：Centos7.4 (CentOS-7-x86_64-Minimal-1804.iso)
• mysql：mysql8.0.13

卸载系统自带的mariadb-lib

• 查看mariadb版本
  
  rpm -qa|grep mariadb
  
  mariadb-libs-5.5.56-2.el7.x86_64
• 卸载mariadb
  
  rpm -e mariadb-libs-5.5.56-2.el7.x86_64 --nodeps

安装依赖环境

yum install -y openssl-devel.x86_64 openssl.x86_64

yum install -y libaio.x86_64 libaio-devel.x86_64

yum install -y perl.x86_64 perl-devel.x86_64

yum install -y perl-JSON.noarch

yum install -y autoconf

yum install -y wget

yum install -y net-tools

关闭防火墙

systemctl stop firewalld.service

systemctl disable firewalld.service

禁用selinux

vi /etc/selinux/config

将SELINUX=enforcing改为SELINUX=disabled

reboot 重启机器

从网易镜像下载mysql安装包集合
