创建用户

create user 'username'@'host' identified by '要设置的密码'
flush privileges;

远程登录时，要给用户的host改为 ‘指定的地址’或者‘%’（任意地址）都可以。

update user set host = '%' where user= 'username'

如果仍然报错

ERROR 2003 (HY000) Can't connect to MySQL server on '192.168.1.8'

可以查看下面的配置

cat /etc/mysql/mysql.conf.d/mysqld.cnf 
#将bind-address=127.0.0.1注释
#bind-address=127.0.0.1
#重启mysql服务
service mysql restart
