1.下载安装yum源
根据系统下载yum源
https://dev.mysql.com/downloads/repo/yum/
rpm -ivh xxxxx.rpm
2.修改yum源
vim /etc/yum.repos.d/mysql-community.repo
enable想要下载的版本
3.安装mysql
yum install mysql-community-server
4.启动
配置里修改了以下datadir路径
vim /etc/my.cnf
启动服务
service mysqld start
查看root初始密码
grep 'temporary password' /var/log/mysqld.log
登录数据库
shell> mysql -uroot -p
此时使用会报错“You must reset your password using ALTER USER statement before executing this statement.”
使用以下步骤设置新密码:
step 1: SET PASSWORD = PASSWORD('your new password');
step 2: ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
step 3: flush privileges;
设置完成后重新登录数据库
