Troubleshooting an Error when Installing Craft on DreamHost
If you’re trying to install Craft on a DreamHost shared hosting account and keep getting the "Oops" screen before it finishes, you’re not alone.
Craft’s install process usually takes anywhere between 10-20 seconds on the vast majority of server configurations. But for whatever reason, Craft’s SQL queries can take 15-20x longer on some DreamHost shared hosting servers. When this occurs, PHP will generally time out, resulting in an incomplete Craft installation.
You can try contacting DreamHost and explain to them what you’re seeing. We’ve seen some occurrences where they will “fix” your shared hosting MySQL instance and speed up the queries, but more often than not, they’ll request that you move to a dedicated VPS plan.
