启动服务:
systemctl start mysqld
重置root密码
查看随机生成的密码
grep 'temporary password' /var/log/mysqld.log
修改root用户密码
mysql -u root -p
mysql> Enter password: (输入刚才查询到的随机密码)
mysql> SET PASSWORD FOR 'root'@'localhost'= "Jstw@123";
开放外部网段访问3306端口
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Jstw@123' WITH GRANT OPTION;
mysql>FLUSH PRIVILEGES;
mysql> exit
这里设置开机自启动

方法二 、 执行 systemctl enable mysqld.service
(# 注意systemctl 中规定、服务的配置文件要以.service 为后缀
开启防火墙mysql 3306端口的外部访问
firewall-cmd --zone=public --add-port=3306/tcp --permanent
firewall-cmd --reload
