Control Panel Migration: Page 2 - Enhance Control Panel

Control Panel Migration

In the clear up part of this introduction:

Once you are happy with the transfer, delete /var/orchd/orchd.sql and /var/orchd/authd.sql from the new backup server.

I guess, the "new backup server" should be "the new control panel server", is it right? @Adam

Aliysa_Enhance

bgeek You're right that should be 'new control panel server' (backups on the mind!)

The guide will be updated with this correction asap.

bluelinq-computers

Aliysa_Enhance The guide doesn't appear to be updated yet, additionally, I am having issues and cannot access the panel

xyzulu

Suggestion: No production server should be allowing root login (or at least not with a password). Many VPS providers provision like this out of the box now. The guide should instead be updated to use a non-root user account, or ssh keys.

Aliysa_Enhance

xyzulu This is absolutely good practice however, we feel that this is outside the scope of this guide.

blestaclub

xyzulu I agree, But they are most likely trying to minimise support requests! lol It's on the user to factor in security

MediaLabz

There was previously talk that when control panel migration came, there would be the ability to fall back to a secondary control panel on another server if the primary control panel fails. Any idea when this would be a possibility?

Aliysa_Enhance

MediaLabz This is still a planned feature, first mentioned over at https://community.enhance.com/d/397-hight-availibity-fault-tolerant-control-panel/21. I'm afraid there are no timescales to share for the availability of this feature.

Aliysa_Enhance

bluelinq-computers The guide has been updated very recently. Please email support@enhance.com and we'll be able to help resolve.

@Adam Aliysa_Enhance

stuck here

root@ubuntu-8gb-fsn1-1:~# sudo -u orchd pg_dump -O -d orchd > /root/orchd.sql could not change directory to "/root": Permission denied

Any recommendations?

boltflare Open a ticket with Adam! He's assisting me right now. It's mostly a pain-free process!

My solution:

I overlooked the actual CTL website. It contains it's own explicit DNS records independent of the apex domain your panel is on. However, when I tried accessing these DNS records -- there was an endless spinning icon trying to load them. When I ran pdnsutil list-zone on the full A record of panel.apex.com it showed my outdated records on the DNS servers.

I used a similar approach as to what @rdbf did with the primary CTL addresses. Made an alias, set to primary, deleted previous primary and then restored. Something was wrong with the primary panel DNS fetching.

All is well now.

For anyone experiencing this and stopping:

boltflare

These errors are expected when run in certain contexts. You'll notice if you cd to that directory, the files are actually created.

The migration process is pretty seamless other than those minor hiccups.

MediaLabz

boltflare Did you find out how this was resolved? I'm experiencing the same error.

boltflare

bluelinq-computers Thanks for your reply. Just opened a ticket.

BTW can you please share the guidelines that you have recieved from Adam. Many folks are trying to migrate and it will be helpful for all.

bluelinq-computers

boltflare Adam has updated the guide and (to my understanding) the process should be entirely pain-free now.

I migrated without issue and only had minimal downtime due to a small mistake in the guide.

Vendoz

Looking at the guide it seems much less risky than the v12upgrade, I think I'll move it today!

bluelinq-computers

Vendoz Can confirm everything is working as expected!

Vendoz

bluelinq-computers Had some minor problems, but i fixed myself (had to put hostname in the file host and, after the move, i had to manually update the IP of the new CP in the enhance interface), but other than that panel is working, tried some command like reboot, file manager, adding role, etc and phpmyadmin works too, so i'm fine! In a day or two we will see if someone discovers problems 😃

My current control panel server also has the application and database roles on it. When I am moving the control panel role from, would I still have to move all the application and database stuff off it, decommission it, and then reinstall as a new server, moving all the application and database stuff back? Or is there an easier way?

This is how I understand the instructions.

Just thinking out the box would it be possible to also back-up the control panel to the back-up server with the gui and then migrate the control panel to a other server with gui 1 day?

I have not tried to move a control panel yet but a lose of server always come at a unwanted time if it happends this is why the back-up server exist and you can decommission servers. But control panel if that one gets wiped its harder you need a back-up of the control server.

Or even be enable to run 2 control panels like load balancing if 1 goes down you still have a back-up that the whole cluster is not reachable? Think in the sense like how DNS works.

Now I would put the control panel at a datacenter with snapshots. Sub servers websites get back-up to backup server thats fine.

I do like how everything works in Enhance and will start using it soon just preparing for some situations that can happen.

Steamon

Could not edit my post but a secondary control panel is already planned:

Yeah nothing to add like the progression 😃

Side question: We have multiple control panels (on the same control panel server of course), ie for resellers.. but there is only one cloudflare.key file. Are all the cloud flare keys stored in this one file? Or are the reseller keys stored elsewhere?

It's just one file, it's an encryption key for the tokens which are stored in the database.
