Mysql

I woke up one morning to find my Ghost blog unresponsive. It required an unexpected fix. 🔧

It’s no secret that Google Reader is a popular way to keep up with your RSS feeds, but it’s getting shelved later this year.

My quest to get better at Python led me to create a new project on GitHub.

The pv command is one that I really enjoy using but it’s also one that I often forget about.

Regardless of the type of hosting you’re using - dedicated or cloud - it’s important to take network interface security seriously.

If you’re running an operation on a large number of rows within a table that uses the InnoDB storage engine, you might see this error:

This problem has cropped up for me a few times, but I’ve always forgotten to make a post about it.

If you have Excel files that need to be imported into MySQL, you can import them easily with PHP.

If you run a fairly busy and/or badly configured MySQL server, you may receive something like this when attempting to connect:

I found myself in a peculiar situation last week.

MySQL has quite a few cryptic error messages, and this one is one of the best:

I received an e-mail from Tim Linden about a post he made in his blog about backing up MySQL data to Amazon’s S3.

It’s tough to find examples of dumps that can’t be properly reimported on other servers.

One of the questions I receive the most is: “What version of Plesk works with MySQL 5?

After a couple of weeks, my MySQL replication series has come to a close.

There’s a few final configuration options that may help the performance of your slave MySQL servers.

If you want to make a DBA nervous, just let them know that they need to upgrade MySQL servers that are replicating in a production environment.

While many people might find replicating over an external network to be an odd concept, it does have some uses.

On some occasions, MySQL replication can break down if an statement comes from the master that makes no sense to the slave.

In a perfect world, slaves will contain the same data as the master at all times.

If you have a master with multiple slaves, you can get some performance and save money on hardware by splitting data horizontally among your servers.

An often overlooked benefit of MySQL replication is the ability to make reliable backups without affecting the integrity of the MySQL data.

Although performance is a much larger benefit of replication, it provides some redundancy for your application as well.

MySQL replication can increase performance by allowing developers to spread queries over two servers.

MySQL replication may sound complicated, but it can be done easily.

When you dump table data from MySQL, you may end up pulling a large chunk of data and it may exceed the MySQL client’s max_allowed_packet variable.
