Bash Arrays & MySQL
+0 Vote Up -0Vote Down

Student questions are always interesting! They get me to think and to write. The question this time is: “How do I write a Bash Shell script to process multiple MySQL script files?” This post builds the following model (courtesy of MySQL Workbench) by using a bash shell script and MySQL script files, but there’s a disclaimer on this post. It shows both insecure and secure approaches and you should avoid the insecure ones.

SSL/TLS in 5.6 and 5.5 – oCERT Advisory
Employee +1 Vote Up -0Vote Down

Today, oCERT published advisory 2015-003 describing a TLS vulnerability in MySQL and derivative products.  The content isn’t exactly news – it is documented legacy behavior and the subject of an earlier blog post describing how MySQL Server 5.7 solves the problem.  That said, the efforts of Duo Security are certainly appreciated and welcomed – it provides a meaningful context to discuss how to properly …

MySQL bind-address
+0 Vote Up -0Vote Down

While I try to keep things simple, sometimes eliminating options and explanations comes back to haunt me. After posting how to open a Fedora firewall port for a LAMP stack, somebody got trapped by my instructions for installing MySQL on Fedora. They got stuck because they had the following setting in their /etc/my.cnf file:

bind-address=localhost.localdomain

I’d suggested using …

Using MySQL Workbench
+1 Vote Up -0Vote Down

I’ve been setting up a simplified lab environment to let my students learn use in class. This added content will show them how to do reverse engineering with MySQL Workbench.

It’s a complete Fedora image with MySQL and Oracle Database 11g for the course. The uncompressed image is 14GB and the compressed image is 5.3GB. I chose Fedora because it’s the smallest open source image that supports both environments, and Fedora is the closest to Red Hat and Oracle Unbreakable Linux. I’m inclined to make the instance available generally but haven’t figured out the best way to do that.

Here are the new instructions I’m adding and if you have …

MySQL Workbench on Fedora
+2 Vote Up -0Vote Down

The early release of Fedora 20 disallowed installation of MySQL Workbench but the current version allows it. Almost like Tom Cruise’s Edge of Tomorrow without the drama. All you need to do is follow my earlier instructions for installing MySQL on Fedora 20. I’d check your kernel to know whether it’s supported. You can check that with this command:

<shell> uname -r

My Fedora is at the following version:

3.14.8-200.fc20.x86_64

Workbench 6.2, CakePHP’s new ORM, and OKC Meetup on Wednesday
Employee +1 Vote Up -0Vote Down

In the beginning was the MySQL command line and it was good. Verbose yes, error prone yes, and even tedious. But it was good. The UPDATE USER set SELECT_PRIV=’Y’, DROP_PRIV_’Y”, UPDATE_PRIV=’Y’,……,LAST_BLOODY_PRIV=’Y”; type errors have caught of us old timers. But it was still good.

Then came some GUI tools that were okay. Not great but they had their uses.

And then came MySQL Workbench. And it was very good.

Now there is MySQL Workbench 6.2 and it is excellent. It came out in Beta last week and has built on the proven success of its predecessors. All the usual stuff is …

MySQL Workbench is a handy administrative tool. Workbench provides server status information, client connection data, the best user admin interface, a browser for system variables, access to data export, an import/restore function, access to system logs, option file editing, performance reports, and startup/shutdown switch.

This is a snapshot of the dashboard on a laptop running a few very simplequeries.

In the past I have either used the CLI or …
