How to Setup a WordPress MySQL Database in the Cloud

WordPress is the largest website builder platform in the world, supporting over 34% of all websites on the internet today. MySQL is a free open source relational database management system that is leveraged across a majority of WordPress sites, and allows you to query your data such as posts, pages, images, user profiles, and more. As any WordPress developer knows, each installation requires a database in the backend, and MySQL is the database of choice for storing and retrieving your WordPress data.

In order for your WordPress website to be able to access, store and retrieve the data in your MySQL database, it needs to be hosted online through a cloud computing service. ScaleGrid offers a convenient way to setup and configure MySQL hosting for your …

Advanced WordPress Search using WpSolr and ElasticSearch

Finding good content on your website is really important. The search feature improves user interaction and helps you to build a readership on your website. WordPress uses the default MySQL database to perform a search which is not great. MySQL is not built for search and if you are serious about building an authority website on WordPress then the search is the module you need to pay good attention.

I have already implemented WordPress search with ElasticSearch here. In this article, I am going to use and review the amazing product called ‘WPSOLR’ built for search.

What is WPSOLR

WpSolr is an advanced WordPress search plugin that can work with Apache Solr and Elasticsearch.

WPSOLR provides out of the box search solution with the following features:

  • Built-in language, synonyms, stop words.
  • Search filter using checkbox, radio box, …

Replace MariaDB 10.3 by MySQL 8.0

Why migrating to MySQL 8.0 ?

MySQL 8.0 brings a lot of new features. These features make MySQL database much more secure (like new authentication, secure password policies and management, …) and fault tolerant (new data dictionary), more powerful (new redo log design, less contention, extreme scale out of InnoDB, …), better operation management (SQL Roles, instant add columns), many (but really many!) replication enhancements and native group replication… and finally many cool stuff like the new Document Store, the new MySQL Shell and MySQL InnoDB Cluster that you should already know if you follow this blog (see these TOP 10 for features for developers and this TOP 10 for DBAs & OPS).

Not anymore a drop in replacement !

Extending WordPress Dockerfile to use MySQL 5.7 (or 8.0)

Oracle’s website shows End of life for MySQL 5.5 as of Jan 20th of 2019, so hurry up and upgrade!

I am working building some demos for Cloud SQL and one of the requirements I had was to run MySQL 5.7 and WordPress as my sample application. The demo consisted on migrating from a single VM environment with WordPress and MySQL running alongside. The narrative: the site got popular and the database became the bottle neck because of all the shared resources between them and the application. The proposed solution? A minimal downtime migration to Cloud SQL, moving the data layer to a dedicated server.

I am going to be doing this demo a lot of times, so I needed some way to automate it. I thought of doing through Docker. I am not Docker proficient, and to begin with I asked …

Debug a slow Wordpress site

A few days ago my colleague asked me to help him figure out why his Wordpress website was running so slow. Everything seemed fine, the CPU was not busy, the memory was not used much. It was not the network issue because its ping time was very fast. The MySQL database was not slow either. So it was hard for me to debug.

The site returned 504 error initially, but it sometimes could load the page (after a long wait). I checked the Nginx error log and found that the upstream connection was not responded. So it must be something wrong with the PHP code.

I tried many ways which I found on the internet but no success. Most of them were about increasing the timeout or the execution time. By doing that, the page could load but it was still super slow (it loaded in > 1min).

When I sat quietly for a while to think, I realized that plugins could be the issue. There could not be any reason a Wordpress could be that slow unless …

TEXT and VARCHAR inefficiencies in your db schema

The TEXT and VARCHAR definitions in many db schemas are based on old information – that is, they appear to be presuming restrictions and behaviour from MySQL versions long ago. This has consequences for performance. To us, use of for instance VARCHAR(255) is a key indicator for this. Yep, an anti-pattern.

VARCHAR

In MySQL 4.0, VARCHAR used to be restricted to 255 max. In MySQL 4.1 character sets such as UTF8 were introduced and MySQL 5.1 supports VARCHARs up to 64K-1 in byte length. Thus, any occurrence of VARCHAR(255) indicates some old style logic that needs to be reviewed.

Why not just set the maximum length possible? Well…

A VARCHAR is subject to the character set it’s in, for UTF8 this means either 3 or 4 (utf8mb4) bytes per character can be used. So if one specifies VARCHAR(50) CHARSET utf8mb4, …

Contributing to popular frameworks for scalability

Right now we’re volunteering some engineering time to assisting the WordPress and WooCommerce people with scalability issues. In the past we’ve put similar efforts into Drupal.

There are many opinions on these systems out there, most of them sadly negative. We take a different view. Each of these frameworks obviously has their advantages and disadvantages, but the key question is why people use them. When we understand that, we can assess that reasoning, and assist further.

Obviously writing your own code all the way is going to potentially create the most optimal result for your site. A custom tool is going to be less code and more optimal for your situation. However, it also requires you to put in quite a bit of development effort both to create and to maintain that system, including security issues. When you’re big enough (as a site/company) this can be worthwhile, but more and more organisations …
