MySQL Workbench - Top 13 things you should know

MySQL Workbench has come a long way and keeps getting better! I honestly don't think that millage may vary on this one as it is one of the best no-cost GUI tools created for MySQL.

Grant check for query analyzer

While working with the MySQL Enterprise Dashboard I found a small problem when trying to use the Query Analyzer. The test server I am running on had a user used by the dev team that had the following privileges:



GRANT USAGE ON *.* TO 'test_user'@'10.18.%' IDENTIFIED BY PASSWORD 'HASHNOTGIVEN';

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, SHOW VIEW, TRIGGER ON `canoe`.* TO 'test_user'@'10.18.%';

ORACLE won't kill MySQL!

Lets just get it over with!



"MySQL co-founder David Axmark says "Oracle has no real reason to support" the open-source database it's trying to acquire as part of Sun, but he also says "I doubt they'd 'kill' anything." Rather, the real intrigue will center on what happens when Oracle's database customers want to migrate downstream to MySQL.



From a cbronline.com article quoting Axmark:"

MySQL UC 2010?

Soooooooo, is the MySQL conference going to fizzle out in 2010? If you have been busy waiting to see what will happen with Oracle/Sun/MySQL then you probably didn’t notice that the call for papers did not go out to the community for 2010 UC. I don’t know about you but the MySQL Conference is something I look forward to every year and enjoy attending. Just being there is great for networking and keeping up on innovation not to mention getting out of the office for the better part of a… Continue

Broken Index from InnoDB Hot Backup

A very interesting problem came up a while back when testing a rebuild and failover procedure. I had just run a rebuild of a slave server with InnoDB Hot Backup from the master. After the failover, one query on three tables in three different databases was not performing as it should. This was very odd to me given that the same table in all three databases was acting up. Below is the table structure and example query:

Secure Your Server – Tips for DBAs

I have complied a list of a good tips for DBAs to consider when implementing security policies in MySQL.



-- The List

1. Make sure that ALL root accounts (ALL PRIVILEGED accounts) have strong passwords and apply them using hashes not plain text. If you leave the password blank anyone can connect as root without a password and be granted all privileges.



2. For ALL other accounts use passwords and apply them using hashes not plain text.

Security Sensitive Grants

Consider excluding the following grants from users on any production MySQL server.



-- GRANT OPTION

"The GRANT OPTION privilege enables you to give to other users or remove from other users those privileges that you yourself possess." (http://dev.mysql.com/doc/refman/5.1/en/privileges-provided.html#priv_grant-option)



-- RELOAD
