Apache VirtualHost slow lookup

apache virtualhost httpd.conf

Solution 1

Add your virtual hosts to the first line:

127.0.0.1       localhost test.local work.local yii.local

And remove the last line.

That should do the trick. Your vhosts are now an alias for localhost. It's not a good idea to have the same IP-address in multiple lines. This just confuses the DNS-cache.

Solution 2

What fixed it for me was editing httpd-vhosts.conf and changing all instances of:

<VirtualHost *:80>

to:

<VirtualHost 0.0.0.0:80>

It was taking about 2-5 seconds to resolve the host, now it is instant. I did not have to modify the order of my sites in my hosts file. This just makes it use ipv4 instead of ipv6 which I'd bet you don't use anyway.

Solution 3

For anyone who is using Chrome and still gets slow virtual host lookup, you need to change the virtual host name to something else than .local, eg. change test.local to test.dev.

I finally managed how to configure properly httpd.conf for my virtualhost needings. This is the relevant part of httpd.conf file
```
NameVirtualHost *:80

<VirtualHost *:80>
  ServerName localhost
  DocumentRoot /Applications/XAMPP/htdocs/
</VirtualHost>

<VirtualHost *:80>
  ServerName test.local
  DocumentRoot /Applications/XAMPP/htdocs/test/
</VirtualHost>

<VirtualHost *:80>
  ServerName work.local
  DocumentRoot /Applications/XAMPP/htdocs/work/
</VirtualHost>
```
When I access anything on localhost (i.e. http://localhost/phpmyadmin) everything is very fast. Whenever I access test.local or work.local (or others I configured) it spends 10-15 seconds on lookup. The following requests are handled correctly and it's very fast but after a minute or so of inactivity, it has to lookup again.

This is my /etc/hosts file
```
127.0.0.1       localhost
255.255.255.255 broadcasthost
#::1             localhost
fe80::1%lo0     localhost

# Virtualhosts
127.0.0.1       test.local     work.local    yii.local
```
How could I fix this annoying issue?

Thanks, seems like this fixed my issue!

I always missed that first localhost (since that part of my file i glossed over). Merging that one really helped.

Holy **** this so enriched and saved my life! I spent without a doubt one third of the time developing locally waiting for slow loading of local virtual hosts! THANK YOU!

Just tried the above and added my virtualhosts to the first line and made a huge difference!
