$ mysql -h 192.168.1.8 -u root -p Enter password: ERROR 1130: Host '192.168.1.110' is not allowed to connect to this MySQL server
$ telnet 192.168.1.110 3306 host 192.168.1.4 is not allowed to connect to this mysql server
mysql 默认安装是不允许远程登陆,只能通过localhost登录,因此你需要为你访问主机授权.
一. 主机授权
1.1 为主机192.168.1.110授权
$ mysql -u root -p Enter password: mysql> use mysql mysql> GRANT ALL ON *.* to root@'192.168.1.110' IDENTIFIED BY 'mypass'; mysql> FLUSH PRIVILEGES;
1.2 为所有主机授权
GRANT ALL ON *.* to 'root'@'%' IDENTIFIED BY 'scada'; flush privileges;
二. 修改用户密码
update mysql.user set password=PASSWORD('mypass') where user='root'; #5.5 update mysql.user set authentication_string=password('mypass') where user='root'; #5.7 flush privileges;
三. 添加用户账号
创建账号 greentest,指定数据库mygreen。
mysql> CREATE USER 'greentest'@'%' IDENTIFIED BY 'greentest'; mysql> GRANT ALL ON mygreen.* TO 'greentest'@'%' IDENTIFIED BY 'greentest'; 1044 - Access denied for user 'root'@'%' to database 'mygreen'
由于权限问题,运行报1044错误,在mysql服务器上执行上述代码,一切正常。
