Quick Start: Create accounts, Verify Resource Isolation

When initializing access to the MatrixOne cluster, the system will automatically generate a default cluster administrator. The cluster administrator is automatically granted the authority to manage accounts by default, but cannot manage resources under the account.

This document will guide you to use the cluster administrator to create two new accounts, grant the permissions of the accountadmin, and check whether the resource isolation between accounts is implemented.

Before you start

• MatrixOne cluster has been depolyed and connected.
• You have obtained the cluster administrator user name and password (the user name is usually root, and the password can be obtained from MatrixOne's product manager or sales representative).

Steps

1. Log into MatrixOne with the cluster administrator's username (root by default) and password:

   mysql -h 127.0.0.1 -P 6001 -u root -p
   

2. Create a new account:

   • The login username and password of account a1 are: admin1, test123
   • The login username and password of account a2 are: admin2, test456

   create account a1 ADMIN_NAME 'admin1' IDENTIFIED BY 'test123';
   create account a2 ADMIN_NAME 'admin2' IDENTIFIED BY 'test456';
   

3. Use admin1 to log in to account a1, and create data table db1.t1:

   mysql -h 127.0.0.1 -P 6001 -u a1:admin1 -p
   create database db1;
   create table db1.t1(c1 int,c2 varchar);
   insert into db1.t1 values (1,'shanghai'),(2,'beijing');
   

   Use the following command to verify whether the table was created successfully for account a1:

   mysql> select * from db1.t1;
   +------+----------+
   | c1   | c2       |
   +------+----------+
   |    1 | shanghai |
   |    2 | beijing  |
   +------+----------+
   2 rows in set (0.01 sec)
   

4. Login to account a2 using admin2:

   mysql -h 127.0.0.1 -P 6001 -u a2:admin2 -p
   

   Check db1.t1 data in account a1:

   mysql> select * from db1.t1;
   ERROR 1064 (HY000): SQL parser error: table "t1" does not exist
   

   The above command runs an error, which proves that the database db1 in the account a1 cannot be seen in the account a2:

5. The database db1 and table db1.t1 can also be created in the account a2:

   mysql> create database db1;
   Query OK, 0 rows affected (0.03 sec)
   
   mysql> create table db1.t1(c1 int,c2 varchar);
   Query OK, 0 rows affected (0.05 sec)
   
   mysql> insert into db1.t1 values (3,'guangzhou');
   Query OK, 1 row affected (0.05 sec)
   

   Insert different data into table db1.t1 of account a2 from table db1.t1 in account a1 and check:

   mysql> insert into db1.t1 values (3,'guangzhou');
   Query OK, 1 row affected (0.05 sec)
   
   mysql> select * from db1.t1;
   +------+-----------+
   | c1   | c2        |
   +------+-----------+
   |    3 | guangzhou |
   +------+-----------+
   1 row in set (0.01 sec)
   

   It can be seen that even though the database and table in account a1 have the same name, the two databases and tables do not interfere with each other and are completely isolated.
