WampServer

It has been a while since I created a virutal host and I'm having problems.

I just installed the newest release of WAMP64 on a computer which has never had WAMP on it.

I am getting the following messages when I try to create a virtual host. I assume the 2nd and 3rd errors are due to the open failure.

-------------------------------
Warning: fopen(C:/Windows/system32/drivers/etc/hosts): failed to open stream: Resource temporarily unavailable in C:\wamp64\www\add_vhost.php on line 446

-------------------------------------------------

I checked and the hosts file is located at C:\Windows\System32\drivers\etc\ and I can open it in an editor

The virtual host I'm trying to create resides in: C:\wamp64\www\WP

I've tried different virtual host names with no difference in results - I followed the rule "No diacritical characters (éçëñ) - No space - No underscore(_)"

I've tried running WAMP64 normally and I also ran it As Administrator.

What am I doing wrong?

What can I do to deleted the partially defined virtual hosts?

------------------------------------------

If I try to load any of the virtual hosts (click on them in the virtual host list), the browser goes after the Internet domains, not local virtual hosts. Which is exactly what it should do since the virtual host configurations did not complete because the host file could not be opened and, thus, was not updated.

And, as I said before, I've run WAMP normally and also "As Administrator" and the results or the same.

In the past, when editing the host files manually for my own purposes, I've never been able to save the hosts file, even running Notepad As Administrator. When I have needed to change hosts, in the past, I had to start Windows in Safe Mode and then run Notepad As Administrator.

The problem I'm having with WAMP is that, for whatever reason, it can't open the hosts file - I don't know if it could update it if the hosts file could be opened - haven't gotten that far yet.

What other information do you want?

If I delete the entries in the httpd-vhosts.conf file for the virutal hosts which failed to be configured completely, will that remove all traces of them?

Hi,

7 - In the file c:\Windows\System32\drivers\etc\hosts, what are the active lines? * Active means no # at the beginning of the line. --- there are no "actrive" lines, all are comments, i.e., all begin with #

The hosts file should contain a minimum of

127.0.0.1 localhost
::1 localhost

Then for each Virtual Host it should also contain

127.0.0.1 wpdeveloper
::1 wpdeveloper

So yours should look like

127.0.0.1 localhost
::1 localhost

127.0.0.1 wpdeveloper
::1 wpdeveloper

It is ok to edit this file manually.

Hi,

Very often, the hosts file is locked for writing, and sometimes for access, by the antivirus or by another anti-machine.
You have to see in the anti-virus settings to put the hosts file in exception.

Hi,

Quote

Warning: fopen(C:/Windows/system32/drivers/etc/hosts): failed to open stream: Resource temporarily unavailable in C:\wamp64\www\add_vhost.php on line 446

This error is - for me - very strange!
Indeed, if the hosts file cannot be opened or is not writable there should be an error message BEFORE trying to create a VirtualHost :

	elseif($c_hostsFile_writable !== true) {
		$message[] = '<p class="warning">'.sprintf($langues['FileNotWritable'],$c_hostsFile).'</p>';
		$errors = true;
	}

The variable $c_hostsFile_writable is filled when Wampserver is launched by tests on:
- the presence of the hosts file
- the possibility of opening it
- the possibility of writing on it
If everything is possible then the variable is "true". If only one of the possibilities does not exist, then the variable is "false".
In addition, if this variable is "false", there is an error message at the bottom of the Wampmanager icon menu plus an error message une php_error.log file : The file C:/Windows/system32/drivers/etc/hosts is not writable

I disabled my anti-virus (AVG) and tried again, same errors.

I then added C:/Windows/system32/drivers/etc/hosts as an exception in AVG protection and tried again - same errors.

There is no error message at the bottom of the WAMP icon list (shown by left clicking WAMP icon in system tray)

I'm going to start Windows in Safe mode, edit the hosts file, save it, and restart normally - I'll post the results.

I did the following:

I deleted the exception I had created in AVG - don't like exceptions and I'd not had to add any execptions on other comptuers where I've installed and used WAMP.

Copied the hosts file example you showed to the clipboard, pasted it into a new Notepad file, and saved it.

I shutdown Windows and restarted in Safe Mode.

I then used Notepad, running as Administrator, to edit hosts file and put in the example you provided. aved the file and restarted Windows in normal mode.

I tried the virtual host wepdeveloper (the example you provided and that I put in the hosts file) and I was able to pull the site up.

I tried to create another virtual host and got the same messages I've reported earlier.[/list]

So, I have a work-around to create new virtual hosts but the automated method is still failing.

One more thing - everytime I start WAMP (using the Programs Menu item created during installation) I get the "do you want to run this program from an unknown author" sort of message and I have to click Yes to start WAMP.

I don't remember ever seeing that on other computers running WAMP. Is there a way to get rid of that message?
