automatically restart apache

[PatrickVeenstra]

Once in a while my sites go down because Apache does.
Is it possible to automatically restart Apache when it is down or "Failed to receive status information from Apache."?

 

[Eminds]

You should first check why apache going down .. check the logs on the server to rectify the issue and fix it instead of setting up some thing that will restart the apache.

 

[Jcats]

cPanel has ChkServd which does exactly that.

TailWatch - cPanel Knowledge Base - cPanel Documentation

But as Eminds states, it is best to check the error logs to find the reason why its going down to prevent it from having to be auto restarted as its just a band aid.

 

[PatrickVeenstra]

Service Manager / tailwatchd is already monitoring Apache. How often does it run?

BTW There's nothing in Apache's error_log at the times the sites go down.

 

[Jcats]

I believe its every 5 minutes, cannot find anything in the docs confirming this.

When the sites go down, what error does your browser display? Its possible Apache isn't going down but restarting it is fixing a different issue maybe something related to PHP.

 

[cPanelMichael]

Hello,

You can browse to "WHM >> Service Manager" to ensure Apache is monitored and automatically restarted if it's detected as down:

Service Manager - Documentation - cPanel Documentation

However, it's a good idea to review /usr/local/apache/logs/error_log to see what's actually happening with Apache, as mentioned in the previous posts.

Thank you.

 

[PatrickVeenstra]

When the sites go down, what error does your browser display?

None. The server simply doesn't respond.

@cPanelMichael as I mentioned in tiny letters at the bottom of my former post, there's nothing in /usr/local/apache/logs/error_log

 

[Jcats]

Not too sure how to help you on this one, you may want to open a ticket up with cPanel then or hire someone with a bit more knowledge.

If you happen to be on the server when its happening again, you can run a few commands that will allow us to better help you like:

# ps aux
# free -m

paste the output into here.

 

[PatrickVeenstra]

Thanks, I'll do so, although I doubt that memory is an issue, because usually I have over 20GB of available RAM.

 

[cPanelMichael]

Hello,

You may also want to review /var/log/messages and /var/log/dmesg for the time-stamps when this issue occurred to see if you notice any abnormal output.

Thank you.

 

[PatrickVeenstra]

Thanks Michael, but there's nothing at the time of an "outage" in /var/log/messages

What am I supposed to look for in /var/log/dmesg ?

[cPanelMichael]

Hello,

You're looking for anything to suggest a problem with the server or the server's hardware. Since there's no output in the Apache error log, it suggests a problem with the server itself.

Feel free to open a support ticket using the link in my signature if you'd like us to take a closer look and rule out any issues with cPanel or Apache. You can post the ticket number here so we can update this thread with the outcome.

Thank you.

Support Request ID is: 8252137

I've included a link to the downtime report within the ticket description.

 

[PatrickVeenstra]

Seems that MaxRequestWorkers was reached. I've doubled Max Request Workers (300) and Server Limit (512).

Maybe with the amount of RAM I have available I should put in higher values, but I don't know about any possible side effects.

Hello,

Let us know if this helps to address the issue.

Thank you.

 

[PatrickVeenstra]

It did not

 

[cPanelMichael]

Feel free to reply to the ticket if the issue continues if you need us to take a closer look to rule out any issues with the cPanel software. Note that generally you should seek out the help from a qualified system administrator for these types of issues, as they relate to resource usage/optimization. You can find a list of system admin services at:

System Administration Services | cPanel Forums

Thank you.
