WordPress migration complete! (From OpenShift Online to a VPS)

If you’re reading this then I’ve successfully migrated this WordPress site from Red Hat OpenShift Online to hosting in a Virtual Private Server (VPS). I had a rather long list of tasks for the migration, including:

  • Exporting content from the old site and importing to the new
  • Re-issuing my SSL certificate and installing on the new server
  • Updating my DNS config
  • Unassociating my deployed app on Openshift with my domain name / alias
  • Installing my WordPress plugins, such as reCAPTCHA, view counter, the importer etc

I’m probably still missing some minor config items, but at this point I think I’m far enough to make the switch, so the site is now live on my new VPS hosting.

Given that I’m only running on a 2 core, 512MB RAM VPS, the new site is surprisingly snappy, and dare I say it, noticeably quicker than when it was running before on OpenShift Online? I’m sure I’ve still got plenty to tweak and configure, but so far so good, and I’m pleased with the transition!

Manually disabling WordPress plugins

If you’re adding new plugins to your WordPress site, depending on the plugin type you can end up with your site being inaccessible if the plugin configuration is wrong. A good example is adding Google’s reCAPTCHA plugin. If you activate the plugin but the config is not correct, for example if your site id is not matching your domain name, AND if you’ve added the reCAPTCHA on your login form, you can end up in a position where you’re completely unable to log on to your site.

Luckily if you can ssh into your server, you can disable a plugin easily by just removing or renaming the plugin folder, for example in your wp-content/plugins folder.

Increasing media upload size for WordPress / PHP5

On a default WordPress 4.8 install on PHP5 the default file upload size seems to be (at least on my install) 2MB. If you’re uploading large image files or videos, it’s likely you’ll want to upload files much larger than this.

There’s a number of possible configuration locations that can control/configure the upload size. The first location is likely to be your php.ini file used by your apache or nginx. The settings to increase are:

  • post_max_size (must be larger than upload_max_size)
  • upload_max_filesize
  • memory_limit

This article has a comprehensive walkthrough the possible configuration changes.
