数据库开启远程访问

先开放3306端口
#开放3306
firewall-cmd --permanent --add-port=3306/tcp 

systemctl restart firewalld.service

#查看端口是否开放
firewall-cmd --query-port=3306/tcp

查看所有开放端口
#list
firewall-cmd --list-all

最后修改数据库远程访问权限

mysql>use mysql
mysql>grant all privileges on *.* to 'root'@'%' identified by 'xxxxx(密码)';
mysql>flush privileges;
