Mysql默认是不允许远程连接的,因为有很大的安全隐患。
方法一、本地登入mysql,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,将"localhost"改为"%"
#mysql -u root -proot
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
mysql>flush privileges;
方法二、直接授权(推荐)
从任何主机上使用root用户,密码:youpassword(你的root密码)连接到mysql服务器:
# mysql -u root -proot
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;
允许地址202.11.10.253上用root用户,密码dboomysql来连接mysql的所有数据库,付给select,insert,update,delete权限。
# mysql -u root -proot
grant select,insert,update,delete on *.* to root@"202.11.10.253" Identified by "dboomysql";
允许地址202.11.10.253上用root用户,密码dboomysql来连接mysql的所有数据库,付给所有权限。
# mysql -u root -proot
grant all on *.* to root@"202.11.10.253" Identified by "dboomysql"
flush privileges;
