Linux 安装mysql 8.0

1 https://dev.mysql.com/downloads/repo/yum/
选择对应的linux版本

复制下载链接
2 wget https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm
3 rpm -Uvh mysql80-community-release-el7-7.noarch.rpm
4 yum -y install mysql-community-server
如果此步骤出现 报错 pageERROr 的错误
vim /etc/yum.repos.d/mysql-community.repo

如果安装的是 mysql8.0 8.0的 gpgcheck=0
依旧报错 请 yum clean all 清除云缓存 再次 yum install mysql-community-server
5 systemctl start mysqld 启动mysql
6 systemctl status mysqld 查看mysql状态
7 cat /var/log/mysqld.log | grep password 查看临时密码

8 mysql -u root -p 登录
9 alter user ‘root’@‘localhost’ identified by ‘你的密码’; 修改密码 需要复杂点

因为mysql 8.0 必须修改密码后 才能修改密码强度
10 set global validate_password_policy=0; 修改密码强度 8.0 set global validate_password.policy=0;
11 alter user ‘root’@‘localhost’ identified by ‘你的密码’; 修改密码
12 结束
