Subject Apachectl hanging if server not up
Date Thu, 13 May 1999 03:06:55 GMT
Hi,

I wrote a little script to check my web server and see if it's up which is
just a front end to apachectl using the "status" and "start" commands.
However, there is a problem with apachectl... if you do a "status" request
and the web server is not up, lynx hangs trying to open a TCP connection...
for minutes, not seconds. This is fine for human use of apachectl because
you just terminate it when it hangs, but this breaks my script.

Here's my solution:

        if $HTTPD -t; then

No need running lynx to get the status page if the server is not up...

Perhaps there is a way to set a timeout on lynx, but I don't see it.

(On second thought, my little script was useless.. I should just do a
"apachectl start" which does not start the server if it looks like it's
running. Sigh.)
