yum or rpm？
yum安裝方式很方便，但是下載mysql的時候從官網下載，速度較慢。
rpm安裝方式可以從國內鏡像下載mysql的rpm包，比較快。rpm也適合離線安裝。
環境說明
- 操作系統：Centos7.4 (CentOS-7-x86_64-Minimal-1804.iso)
- mysql：mysql8.0.13
卸載系統自帶的mariadb-lib
- 查看mariadb版本
rpm -qa|grep mariadb
mariadb-libs-5.5.56-2.el7.x86_64 - 卸載mariadb
rpm -e mariadb-libs-5.5.56-2.el7.x86_64 --nodeps
安裝依賴環境
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
關閉防火牆
systemctl stop firewalld.service
systemctl disable firewalld.service
禁用selinux
vi /etc/selinux/config
將SELINUX=enforcing改為SELINUX=disabled
reboot 重啟機器
