拿到登录密码登录mysql
mysql -u root -p

ALTER USER 'root'@'localhost' IDENTIFIED BY '你的新密码'
开启mysql远程访问并允许连接
use mysql;
UPDATE mysql.user SET Host='%' WHERE User='root'; FLUSH PRIVILEGES;
更改host并刷新权限
在关闭防火墙的状态下，现在使用navicat工具就可以连接上centos的mysql了
如果有防火墙，开放3306端口
firewall-cmd –zone=public –add-port=3306/tcp –permanent
更新防火墙规则
firewall-cmd –reload
安装完毕
