centos7下mysql8安装

wget -i -c https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm rpm -ivh mysql80-community-release-el7-7.noarch.rpm yum update 报错 用 yum update --nogpgcheck ok了 yum install mysql-server 设置开机启动 systemctl enable jenkins.service 注意 1、/etc/my.conf 最后不带/ datadir=/service/mysql/data 2、centos 7 必须关掉，永久关掉selinux，不然mysql还目录不成功，会报没权限
