Can someone translate this HTTPD error?

I have the exact same errror.

similar problem here. The web server goes down for a few minutes at a time, many times a day. (Mac mini 10.7.2)

Let's go to end of the universe!! step by step =)

Aug 25 14:11:55 myserver org.apache.httpd[37303]: [Thu Aug 25 14:11:55 2011] [warn] NameVirtualHost 83.246.3.34:80 has no VirtualHosts

That means that "below your NamedVirtualHost specification there is no Virtual Host defined"

VirtualHost are here to allow you to have multiple web pages below the same IP.

A common Virtual Host definition is:

NameVirtualHost *

<VirtualHost *>

ServerName www.domain.tld

DocumentRoot /www/domain

</VirtualHost>

<VirtualHost *>

ServerName www.otherdomain.tld

DocumentRoot /www/otherdomain

</VirtualHost>

Following your Log, you have a "NameVirtualHost 83.246.3.34:80" definition without any following "<VirtualHost 83.246.3.34:80>" directive.

All site's configuration files are in /etc/apache2/sites/

Aug 25 14:11:57 myserver org.apache.httpd[37310]: [Thu Aug 25 14:11:57 2011] [warn] _default_ VirtualHost overlap on port 80, the first has precedence

Aug 25 14:11:57 myserver org.apache.httpd[37310]: [Thu Aug 25 14:11:57 2011] [warn] _default_ VirtualHost overlap on port 443, the first has precedence

That two messages means the same, that "there are two identical VirtualHost definitions, so i'll use the first one"

That means that you have two "<VirtualHost XXX>" directives with the same or missing "ServerName" definition.

The Web Server a.k.a. Apache uses the "ServerName" to forward request to one or other definition.

Let's see an example with this missconfiguration:

NameVirtualHost 83.246.3.34:80

<VirtualHost 83.246.3.34:80>

ServerName www.domain.com

DocumentRoot /www/domain

</VirtualHost>

<VirtualHost 83.246.3.34:80>

ServerName www.domain.com

DocumentRoot /www/otherdomain

</VirtualHost>

... when a connection is made to www.domain.com resoults in going to 83.246.3.34 port 80

Then Apache doesn't know where to go (/www/domain or /www/otherdomain) so it will go to the first definition

Aug 25 14:11:57 myserver com.apple.launchd[1] (org.apache.httpd[37310]): Exited with code: 1

Aug 25 14:11:57 myserver com.apple.launchd[1] (org.apache.httpd): Throttling respawn: Will start in 10 seconds

This means "Apache process exit with errors, will try to restart it in 10 sec".

Note that previous errors should not make Apache process die.

Aug 25 14:11:58 myserver servermgrd[36879]: servermgr_web: waiting for pid, file /private/var/run/httpd.pid.

Aug 25 14:12:02 myserver servermgrd[36879]: servermgr_web: Cannot confirm Apache was started; missing or invalid pid file

The ".pid" file is just a text file with the process number in it (in this case, 36879).

This file helps other process to kill or restart the Apache's process if needed.

That say that "no .pid file was created, or invalid file was created, for example an empty one".

Stop the Web Server and check that the .pid file is not there (/private/var/run/httpd.pid).

Start the Web Server and check that the .pid file is there and has the propper content.

You can get the PID (Process ID) for a process performing a "ps" command from the command line:

#ps aux | grep http

make the force b with u!

[Thu Aug 25 14:15:23 2011] [error] Oops, no RSA or DSA server certificate found for 'myvirtual.mydomain.com:0'?!

That means that "you have configured a SSL VirtualHost, and you have not defined the certificate to encrypt that!"

Disable the 443 port in apache, or the SSL itself, and the error should go away.

In fact, the domain which doesn't have the certificate is "myvirtual.mydomain.com:0", weird default missconfigured domain.....

Here I make my guess, has you started the Web Service without configuring anything? =)

You have to configure at least one VirtualHost before starting the Web Service, a.k.a. Apache.

I think you all have the same problem:

You have deleted the default site, and/or have some missing configuration parameters.

Appart from other "special" web services (like wiki, profile manager, etc) you need to define a default site in Server.app > Web

Let me know if that helps!!
