Third, set the MySQL root account password

2. If you have finished setting the password, you need to modify it, execute the command

Mysqladmin-u root-p  Password latest password

You will then be prompted to enter your password, enter your old password, return

Iv. Connecting the database

Mysql-u root-p

Then prompt for a password, enter the initial password set in the three

2. If you log in to the MySQL database on the remote host

Mysql-h host Address-u user name-P user Password

V. Perform common MySQL database operations

Note: The following actions are sent now, after connecting to the database, enter the MySQL environment, then execute the command must have a semicolon ";"

First, connect to MySQL with root privileges

Mysql-u root-p

Then, enter the root password

1. Add new users

The format is as follows:

Grant operation permissions on the database. * To username @ Login host address identified by ' password ';

Grant, a user on a host (with the user's login password) on a database, perform certain actions permissions

(1) For example: on any host ("%"), the user (user name: test1, Password: ADC) on all databases, perform arbitrary operation permissions (very dangerous)

Grant all privileges on * * to [email protected] '% ' identified by ' ABC ';

Where all privileges means query, insert, modify, delete permissions: Select,insert,update,delete

The above command is equivalent to:

Grant Select,insert,update,delete on * * to [e-mail protected] "%" identified by "ABC";

And then refresh the permissions

Flush privileges;

(2) For example: permission to authorize the user to operate the database on the local host

Create a database (for example: OpenFire)

Create Database OpenFire;

Grant Local Host User (user name: test2, Password: 123) Access database (database name: openfire) Operation permissions

Grant all privileges the openfire.* to [e-mail protected] identified by "123";

Flush privileges;

After that, you can access the OpenFire database with a new user.

Delete from user where user= "test7" and host= "localhost";

4. Show commands

Use OpenFire;

(3) Show all tables in this library

Show tables;

(4) Show the structure of a table (table1)

Describe Table1;

(5) Building a library

Create database name;

(6) Building a table

Use library name; CREATE table table name (field settings list);

(7) Delete the library
