I currently have two configuration profiles on my Linode. One is an older Debian Lenny system, the other a newer Squeeze configuration

I'm currently in the process of moving files from one to the other. I'd like to be able to use my SSH client software to log on to both profiles, so I can move files around before making the final switchover. Is there any way to be able to run both profiles at once? Failing that, is there an efficient way to copy files from one profile to the other?

Also, is there a FAQ on the forums explaining the best way to switch web site URLs from one configuration to another?

Thanks,

- Chris

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 . . .

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

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!)
