MySQL notes

The situation is that I have a MySQL database instance somewhere out on the network. And I'm trying to connect to it.

Logging in from the DB host

Plan:

  • Open a terminal window on the DB host, 192.168.1.130
  • Attempt to connect as the root db user
[root@zyxx01 ~]# mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

That didn't work. This does, though:
 
[root@zyxx01 ~]# mysql -u root -p
Enter password: ****
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 171310
Server version: 5.5.32-log MySQL Community Server (GPL)

mysql>

So, don't forget the -p option on the command-line. I guess that it tries first to connect without a password, which is a possible configuration for MySQL. And fails because it isn't allowed in this instance.

Logging in from remote machine

My first attempt here didn't work either, because "mysql" actually runs a batch file which expands into:

D:\>c:\progra~1\mysql\mysqls~1.5\bin\mysql.exe --defaults-file=c:\ProgramData\MySQL\mysqls~1.5\my.ini -uroot -p
Enter password: ********
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)

Invoking the .exe directly avoids that interesting "defaults-file" thing:
D:\>c:\progra~1\mysql\mysqls~1.5\bin\mysql.exe -h 192.168.1.130 -u root -p
Enter password: ********

Cool, we're in. So now, let's create a user:

mysql> create user 'abacab'@'%' identified by '****';
Query OK, 0 rows affected (0.00 sec)

mysql> grant all privileges on *.* to 'abacab'@'%' ;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql>

Testing the user:

D:\>c:\progra~1\mysql\mysqls~1.5\bin\mysql.exe -h 192.168.1.130 -u abacab -p
Enter password: ***********
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 206648
Server version: 5.5.32-log MySQL Community Server (GPL)
...
mysql>

Success.
