No you can't boot both at the same time.

To move files from one to the other (say lenny to squeeze), edit the profile for squeeze and add the root lenny drive as another parition, boot into the squeeze profile and mount the lenny drive, then you can simply copy the files using cp.

Switching websites shouldn't be a problem if they're both the same configuration they will also share the same ip, so as long as your webserver configurations are the same it should work fine.

Thanks – I'll give that a try!

Hi,

I finished copying my files to the Squeeze profile. Just as a sanity check, I left the sites-available and sites-enabled directories with their default values, and added

NameVirtualHost 72.14.179.185:80

to end of apache2.conf

I then pointed my browser to the Linode's numerical URL, and got the Apache default page, so I know Apache is working on the new Squeeze profile.

The problem came after I copied over my sites-available and sites-enabled directories from the Lenny profile, and rebooted. When I typed the following to activate my bookgenius.org website:

a2ensite bookgenius.org

I got this error message:

root@li41-185:/etc/apache2# a2ensite bookgenius.org

ERROR: Site bookgenius.org not properly enabled: /etc/apache2/sites-enabled/bookgenius.org is a real file, not touching it

And, not surprisingly, my browser can't connect to the website. Can you tell me what the problem might be? I suspect I left out a step in enabling the website.

Thanks,

• Chris

/etc/apache2/sites-enabled/bookgenius.org should be a symlink from /etc/apache2/sites-available/bookgenius.org put the config file in /etc/apache2/sites-available/bookgenius.org, delete /etc/apache2/sites-enabled/bookgenius.org then run a2ensite bookgenius.org and restart apache.

I did all that , then ran a2ensite bookgenius.org again. It worked, and said the site was enabled.

But when I restarted Apache, I still could not connect to the site. I looked in the sites-enabled directory, but didn't see any files there. Hmmm . . .

How to ask for help

1. Give details of your problem

2. Post any errors

3. Post relevant logs.

4. Be polite or you'll be eaten by a grue

Try linking manually ln -s /etc/apache2/sites-available/bookgenius.org /etc/apache2/sites-enabled/bookgenius.org then restart apache

When I typed that line, I got:

root@li41-185:/etc/apache2# ln -s /etc/apache2/sites-available/bookgenius.org /etc/apache2/sites-enabled/bookgenius.org

ln: creating symbolic link `/etc/apache2/sites-enabled/bookgenius.org': File exists

It turns out there already was a bookgenius.org ORG file in sites-enabled, but I had neglected to refresh the directory when I was looking earlier (sorry!). I rebooted, but still cannot connect to the site.

bookgenius.org points to 72.14.179.185 assuming that is your linode ip it's not accepting http connections.

What's the output of netstat -lpnt and iptables -L -n -v

One more clue. If I use the default apache2.conf file, I can connect to the bookgenius.org site, but I get only the default Apache html page. When I try to swap in my .conf file from my Lenny setup, that's when I am unable to connect to the site at all. So I suspect there must be something in that file that the Squeeze configuration doesn't like.

check the contents of your apache error log

for netstat:

Try binding apache specifically to your linode's ip address

In var/log/apache2, at the end of the list, I see:

Can you tell me how I can bind apache to my linode's ip address – or perhaps point me to where I can find out? Sorry, I'm new to this aspect of using the Linode.

(Thanks so much for all your help, by the way!)

Checkout http://httpd.apache.org/docs/2.2/mod/co … irtualhost">http://httpd.apache.org/docs/2.2/mod/core.html#virtualhost you put the ip in the virtualhost instead of * you also will want to check out if it's listening on the ip which is in /etc/apache2/ports.conf i.e. Listen 72.14.179.185:80 and NameVirtualHost 72.14.179.185:80

I see another clue in the contents of ports.conf, specifically about having to do certain things when upgrading from Etch:

If you just change the port or add more ports here, you will likely also

have to change the VirtualHost statement in

/etc/apache2/sites-enabled/000-default

This is also true if you have upgraded from before 2.2.9-3 (i.e. from

Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and

README.Debian.gz

NameVirtualHost *:80

Listen 80

# If you add NameVirtualHost *:443 here, you will also have to change

the VirtualHost statement in /etc/apache2/sites-available/default-ssl

to # Server Name Indication for SSL named virtual hosts is currently not

supported by MSIE on Windows XP.

Listen 443

Listen 443

So far, I'm stumped. It might make more sense for me to start at the beginning with a new Squeeze profile, and get the web sites up and running before doing anything else.

Thanks again!

OK, I got the virtual server working! (I had neglected to restart and reload the apache server. I think that was the problem. I also carefully followed the steps outlined at http://library.linode.com/web-servers/a … al-hosting">http://library.linode.com/web-servers/apache/installation/debian-6-squeeze#sph_configure-apache-for-named-based-virtual-hosting)

I do have a question: when I did reload the server, I got these warnings:

root@everything:~# /etc/init.d/apache2 restart

Restarting web server: apache2apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

[Thu Dec 15 15:35:30 2011] [warn] NameVirtualHost *:80 has no VirtualHosts

… waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

[Thu Dec 15 15:35:32 2011] [warn] NameVirtualHost *:80 has no VirtualHosts

.

I'm not quite sure what the warning means. I do see content from the web site in my browser now, so I know it's working.
