Hi.
I have an Apache/PHP/MySQL server setup on a droplet, and sometimes the server will “go down” and the sites will time out in a browser.
Restarting Apache resolves the issue for the time being, but I did that last night only to find the site down again this morning (so I rebooted Linux), so I’m concerned.
I found a 3rd party service that lets me know when this happens, but I can’t always be there to restart the system.
The general Apache error log did not show anything out of the ordinary as far as I can tell. I know enough to be dangerous on Linux as long as I can Google things, but this is beyond me.
I spent a lot of time tightening security, and while I have seen dozens of hack attempts a minute within the first hour of the server going up, I’m fairly sure it’s reasonably locked up.
What steps can you recommend I take to track down this issue?
Are there any tools I can use to automatically restart apache when there’s an issue?
Thanks!

For the hack attempts, why not have a look at Cloudflare free plan, it helps protect against cross site scripting and DDoS attempts.
Regarding your timeouts, its probably from exhausted server memory / cpu. Check your memory, cpu and server load with htop (sudo apt-get install htop) and then run command htop.
