Configure WordPress MultiSite on Synology NAS

Hi there!

I’ve been running a single WordPress Site on my Synology NAS since a while. Recently I wanted to create an additional site, also hosted on my Synology NAS.

After a bit of googling, I concluded that the most adequate solution for me would be a WordPress MultiSite aka Network. In this post I quickly summarize how I set this up.

  1. Back up your site (just in case)
  2. Deactivate the plugins
  3. Update the ‘wp-config.php’ file on the Synology
    • Connect to your Synology NAS
    • Start File Station and navigate to web-packages / wordpress
    • Download ‘wp-config.php’ to you PC
      (Initially I intended modifying the file directly on the NAS using the Text Editor but for some reason I was not able to save the modified file due to access rights issues even though I connected as Administrator, hence the need for a download. If you find a way to modify the file directly on the NAS, let me know how!)
    • Look for the following entry in the file:
      /* That’s all, stop editing! Happy blogging. */
    • Add the following just above:
      /* Multisite */
      define( 'WP_ALLOW_MULTISITE', true );
    • Save the file and upload it to the NAS (overwriting the existing file)
  4. Install MultiSite
