Many of my friends have installedMysqlBut I don't know how to use it. In this article, we will learn some common MYSQL commands from the aspects of connecting to MYSQL, changing the password, and adding users.
1. Connect to MYSQL.
Format: mysql-h host address-u user name-p user password
1. Example 1: Connect to MYSQL on the local machine.
First, open the DOS window, enter the directory mysqlbin, and then type the command mysql-uroot
-P: after you press enter, the system prompts you to lose the password. If you have just installed MYSQL, the super user root has no password, so press enter to enter MYSQL. The MYSQL prompt is: mysql>
2. Example 2: Connect to MYSQL on the remote host. Assume that the IP address of the remote host is 110.110.110.110, the user name is root, and the password is abcd123. Enter the following command:
Mysql-h110.110.110.110-uroot-pabcd123
(Note: You do not need to add spaces for u and root. The same applies to others)
3. exit MYSQL command: exit (press enter)
2. Change the password.
Format: mysqladmin-u username-p old password new password
1. Example 1: add a password ab12 to the root user. First, enter the directory mysqlbin in DOS, and then type the following command
Mysqladmin-uroot-password ab12
Note: Because the root account does not have a password at the beginning, the old-p password can be omitted.
2. Example 2: change the root password to djg345.
Mysqladmin-uroot-pab12 password djg345
3. Add new users. (Note: Unlike the above, the following commands in the MYSQL environment are followed by a semicolon as the command Terminator)
Format: grant select on database. * to username @ login host identified
"Password"
Example 1: add a user named "test1" with the password "abc" so that the user can log on to any host and have the permission to query, insert, modify, and delete all databases. First, use the root user to connect to MYSQL, and then type the following command:
Grant select, insert, update, delete on *. *
