centos6或7使用Yum安装mysql8.0

能够指定版本，如8.0.11，8.0.12，8.0.13，8.0.14，8.0.15，8.0.16

添加mysql yum repository

mysql80-community-release-el7-3.noarch.rpm

yum-config-manager --enable mysql80-community

yum repolist enabled | grep mysql

yum clean all

yum makecache

yum install mysql-community-server -y

yum install mysql-community-client mysql-community-devel mysql-community-libs mysql-community-server mysql-community-common --skip-broken -y

systemctl start mysqld.service

禁止自动更新

tail -1  /etc/yum.conf

exclude=mysql-community-*

centos6同centos7,安装就是yum repository不同，如mysql80-community-release-el6-3.noarch.rpm
