Question
Does anyone know if while Apache HTTPD is doing a reload (which, let's say, takes five seconds) can it still serve requests during that time?
Solution
First of all, you say reload, but assuming you mean 'reload' OR 'restart':
/my/path/to/httpd restart
- Causes the current httpd process to exit, which means for a time the server appears to be down, as in not serving any requests.
Reload on the other side:
/my/path/to/httpd reload
- Does not cause the current server to exit, which means connections are never refused and thus the server never looks down (but is rather slow for a little while)
- Will cause all long running httpd daemon requests to exit
OTHER TIPS
As far as I know, no. However there is a graceful restart which stops child nodes halting mid-request which I think takes care of this.
