This is a handy tool for administrators keeping an eye on managed and semi-managed cPanel hosting servers. It currently does the following:
- Enumerates all accounts and domains on a list of cPanel servers
- Skips any domains that don't resolve in DNS to the that particular server
- Retrieves the content of the web site and logs it into a file
- Saves a screenshot of the site using PhantomJS
It will eventually be extended to:
- Compare the contents of each web site with its previous snapshot
- If a significant difference is encountered, generate an email that contains an alert, as well as the before and after screenshots
Strategies for evaluating differences might include:
- Comparison of first 1KB only
- Percentage difference of entire page
- Scanning for warning/error messages, e.g. PHP notices
In order to make operation of the tool as automatic as possible, I'd prefer not to have to configure the strategy on a per-domain basis - hopefully I'll come up with something that is generic enough to apply to all of the sites I look after.
It's intended to be run periodically from cron, but you may also wish to invoke it after server-wide PHP or Apache upgrades, WordPress core and plugin upgrades, account moves between servers, and so on.
- Install PhantomJS (tested with 2.0.0)
- bundle install
- Create an access keys in WHM
- Copy servers.yml.sample to servers.yml file and fill in the blanks
