- Apache 2.0.59. Because this is legacy code with proven stability and I don't need the features of 2.2 (yet)

- Yes, linux-guru you are probably hitting your open files maximum. I had this problem too. But I wrote my own logger that uses syslog-ng to centralize my logfiles (I might put it up one of these days). But for now you might want to start Apache with "ulimit -n 65000"

I have this in startup, but it is not enough sometimes after i add this the apache also dont start.

- You say you don't have MySQL running. How come there is a MySQL socket for PHP: MYSQL_SOCKET /var/lib/mysql/mysql.sock?

We have different mysql servers that the applications (php) run on this server connects.

- Besides that linux-guru, you have a ton of open ports running on your server. Might want to check that…. You would probably only need 21, 80 (open) en 22 (filtered).

Have you ever tried to connect to other ports than 21 and 80 ? or 443 ?

I am not sure about that :)

* what kind of storage do you use?

* is it possible for you to send me yor httpd.conf and machine tech spec.s

Does anybody host about 2000-2500 virtual sites in single server?

Which version of Apache do you prefer 2.0 or 2.2 for hosting thousands of websites?

Do you have examples or some experiment about the httpd.conf for this kind of servers?

Have you ever noticed an error like this below;

apachectl stop, OK

apachectl start, No responce. FAIL

open the file which has virtual host records, inc.vhost.httpd.conf put # sign

start of 30-40 lines save and close the file.

apachectl start, OK

open the file again and remove the #'s

apachectl graceful, OK

Please help :) We are getting mad more and more everyday.

You could check the php config and other details at http://82.222.170.52/i.php

We are using Redhat Enterprise Linux 4, we are installing apache , php , and modules from source.

The servers are extremly powerful and does not have other services like mysql or mail server. only apache serving.

Please contact me directly if you think you could help.

Thanks.
