When we use the MySQL database, sometimes our program is not on the same machine as the database, we need to access the database remotely. By default, MySQL users do not have remote access permissions. Here are two ways to solve this problem. 1, change the table method may be your account is not allowed to login from the remote, only in localhost. This time as long as the computer in localhost, log in to MySQL, change the "MySQL" Database in the "User" table "host" item, from "localhost" renamed "%" Mysql-u root-p mysql>use MySQL; Mysql>update User Set host = '% ' where user = ' root '; Mysql>select host, user from user; 2, the authorization method runs on the machine which installs the MySQL: 1, d:\mysql\bin\>mysql-h localhost-u root//This should be able to enter MySQL server 2, mysql>grant all privileges on *. * to ' root ' @ '% ' with GRANT OPTION//give any host access to data for example, you want MyUser to use MyPassword from any host to connect to the MySQL server. Grant all privileges on * * to ' myuser ' @ ' percent ' identified by ' MyPassword ' WI TH GRANT OPTION; If you want to allow the user to connect to the MySQL server myuser from the IP 192.168.1.6 host, and use MyPassword as the password GRANT all privileges on * * to ' myuser ' @ ' 192.168.1.3 ' Identified by ' MyPassword ' with GRANT OPTION; 3, Mysql>flush privileges//Modify effective 4, Mysql>exit quit the MySQL server, so you can be on any other host as root login
