Go MySQL Database 4 "command-line empowerment operations"

The simple format that MySQL gives to user rights commands can be summarized as: Grant permissions on database objects to users

Original: http://www.cnblogs.com/zhuyibo/p/3980328.html

A grant general data user, the right to query, insert, UPDATE, delete all table data in the database.

Grant Select on testdb.* to [email protected] '% '

Grant insert on testdb.* to [email protected] '% '

Grant update on testdb.* to [email protected] '% '

Grant Delete on testdb.* to [email protected] '% '

Alternatively, replace with a MySQL command: Grant SELECT, INSERT, UPDATE, delete on testdb.* to [email protected] '% '

II. Grant Database Developer, creating tables, indexes, views, stored procedures, functions ... and other permissions.

Create, modify, and delete MySQL data table structure permissions.

Grant create on testdb.* to [email protected] ' 192.168.0.% ';

Grant ALTER on testdb.* to [email protected] ' 192.168.0.% ';

Grant drop on testdb.* to [email protected] ' 192.168.0.% ';

FOREIGN Key Permissions

Grant references on testdb.* to [email protected] ' 192.168.0.% ';

Temporary table Permissions

Grant create temporary tables on testdb.* to [email protected] ' 192.168.0.% ';

Index Permissions

Grant index on testdb.* to [email protected] ' 192.168.0.% ';

view, view source code permissions

Grant CREATE view on testdb.* to [email protected] ' 192.168.0.% ';

Grant Show view on testdb.* to [email protected] ' 192.168.0.% ';

stored procedures, function permissions

Grant create routine on testdb.* to [email protected] ' 192.168.0.% '; --now, can show procedure status

Grant alter routine on TESTDB.* to [email protected] ' 192.168.0.% '; --now, can drop a procedure

Grant execute on testdb.* to [email protected] ' 192.168.0.% ';

Iii. Grant General DBA manages permissions for a MySQL database

Grant all privileges on TestDB to [email protected] ' localhost ' "where the keyword" privileges "can be omitted"

Iv. Grant Advanced DBA manages permissions for all databases in MySQL

Grant all on * * to [email protected] ' localhost '

MySQL grant permissions can be used on multiple levels, respectively.

1. Grant acts on the entire MySQL server:

Grant SELECT On *. * to [email protected]; --DBAs can query tables in all databases in MySQL.

Grant all on * * to [email protected]; --DBA can manage all databases in MySQL

2. Grant acts on a single database:

Grant Select on testdb.* to [email protected]; --DBAs can query the tables in TestDB.

3. Grant acts on a single data table:

Grant SELECT, INSERT, UPDATE, delete on testdb.orders to [email protected];

Here, you can execute the above statement multiple times when you grant multiple tables to a user. For example:

Grant Select (user_id,username) on smp.users to [e-mail protected] '% ' identified by ' 123345 ';

Grant Select on smp.mo_sms to [email protected] '% ' identified by ' 123345 ';

4. Grant acts on the columns in the table:

Grant Select (ID, SE, rank) on testdb.apache_log to [email protected];

5. Grant acts on stored procedures, functions:

Grant execute on procedure testdb.pr_add to ' dba ' @ ' localhost '

Grant execute on function testdb.fn_add to ' dba ' @ ' localhost '

Vi. Viewing MySQL user rights

View current user (Own) permissions: show grants;

View other MySQL user rights: Show grants for [email protected];

Vii. revoke permissions that have been granted to MySQL users

Revoke is similar to Grant's syntax, just replace the keyword "to" with "from":

Grant all on * * to [email protected];

Revoke all on * * from [email protected];

Viii. MySQL Grant, REVOKE user rights considerations

1. Grant, after revoke user rights, the user has to reconnect to the MySQL database for the permission to take effect.

2. If you want to allow authorized users, you can also grant these permissions to other users, you need the option "grant option"

Grant Select on testdb.* to [e-mail protected] with GRANT option;

This feature is generally not available. In practice, database permissions are best managed centrally by DBAs
