Mysql8 开放root远程登陆权限
修改my.cnf绑定0.0.0.0， /etc/init.d/mysql restart重启mysqld/etc/mysql/mysql.conf.d/mysqld.cnf
bind-address = 0.0.0.0
mysqlx-bind-address = 0.0.0.0修改表， 开启root远程登陆权限
update user set host = '%' where user ='root';默认root使用的密码插件是socket插件，只能本地认证

Mac app store下载mysql ace， 相当于sequel-pro的升级版（sequel-pro对mysql8支持的不好）
