WordPress bash deployment script

Recently in my current company we had a client asking for a restaurant website. We’ve decided to do it with WordPress and used it as a CMS instead of a blog. Beside the fact that we needed to create the website, they also requested us to make all the maintenance of the website and their blog. What I suggested was to have a staging platform and of course the production platform.

To do make the deployment process from staging to production seamless, I’ve created a WordPress bash deployment script to easily go from staging to production. Some of you will ask me about the development platform? To do so, we’ve used a service called DeployHQ that works pretty well. It fetch all the content of your SVN repository and push it straight to the FTP. The only tricky part was for the database. I know it wasn’t clean but I made the decision to work on the same database for the staging and development part.

If you have any suggestions about improving this script do not hesitate.

Please consider the following on our installation:
