鼠标悬浮在 “No thanks, just start my download.”可查看mysql yum源的地址，选中右键复制链接地址进行下载

cd /usr/srcwget https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm#安装yum源yum localinstall mysql80-community-release-el7-1.noarch.rpm#更新yum源yum clean allyum makecache#开始安装MySQLyum install mysql-community-server#启动MySQLsystemctl start mysqld#启动成功后可以查看初始化密码随机生成的cat /var/log/mysqld.log | grep password#登录MySQL修改mysql用户密码mysql -u root -pmysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpassword';#远程设置mysql> use mysql;mysql> update user set host='%' where user='root';#授权用户名的权限，赋予任何主机访问数据的权限mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;mysql> FLUSH PRIVILEGES;

#启动mysqlsystemctl start mysqld.service#结束systemctl stop mysqld.service#重启systemctl restart mysqld.service#开机自启systemctl enable mysqld.service

端口开放后就可以进行数据库连接操作了，在使用Navicat for MySQL 连接 Mysql 8.0.12可能会出现问题 Client does not support authentication protocol 错误解决方法

#修改加密规则 （这行我没有写，不过貌似也可以）密码需要设置包含大小写字母符号和数字的格式，否则设置不会超成功ALTER USER 'root'@'%' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; #更新一下用户的密码 ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'password'; #刷新权限FLUSH PRIVILEGES;
