This is going to be a short one. We’re using WordPress for multiple pages hosted on our schools rootserver now. They share tons of plugins and themes and it is quite a lot effort to maintain all of those on all pages singularly, so I came up with a solution making this process a lot easier: symlinking all the things! So every page accesses a single folder containing all the files.

  1. Copy the needed plugin and theme files to another location outside of the several wordpress root directories.
  2. Symlink the single folder to the original path in your single instances.
  3. Benefit from having to update only one folder for all instances, instead of n folders for n instances.
