Mysql user Authorization

By default, mysql is entered and operated by root users, so if you want to enter and add, delete, modify and query the database as other users, you need to enter the database as root users to authorize the corresponding users.

Server0:/usr/local/mysql/bin # mysql-uroot-p

Enter password:

Mysql > show databases

+-+

| | Database |

+-+

| | information_schema |

| | mysql |

| | solrclient |

| | test |

+-+

Mysql > grant all privileges on solrclient.* to identified by 'suse'

Query OK, 0 rows affected (0.00 sec)

Mysql > FLUSH PRIVILEGES

Query OK, 0 rows affected (0.00 sec)

Mysql >\ Q

There can also be finer-grained authorization:

/ / if you want to assign some permissions to a user, you can write as follows:

Mysql > grant select,update on solrDB.* to identified by 'suse'

3. Delete user

@ > mysql-u root-p

@ > password

Mysql > DELETE FROM user WHERE User='suse'and Host= "localhost"

Mysql > flush privileges

/ / delete the user's

> drop database solrDB

4. Modify the specified user password

@ > mysql-u root-p

@ > password

Mysql > update mysql.user set password=password ('new password') where User='suse' and Host= "localhost"

Mysql > flush privileges

Mysql > quit
