Centos 6.5 or 7

I think this is more of a Webmin question (rather than a CentOS question). CentOS 7 has been out for a year, so should be ready :)

If a Webmin update messed up, I'd suggest you try to figure out what happened. Simply rebuilding doesn't bring a guarentee that it won't happen again…

When I used Webmin, I found their mailing list to be excellent for support:

Webmail will work fine on centos7

Thanks Sleddog. I should have elaborated. I had an issue with webmin and restored from a backup that had my current config and my old config. For some reason my current config was not getting backed up properly. So I was forced to run an old config. On top of that, I did the free upgrade/migrate linode offered and my 32 bit centos would not run on the new server without a kernel update.

After all that, I figured it best to start a new linode fresh. So it seems Centos 7 is probably ok to use. I am now wondering if any of the differences between 6 & 7 will make it difficult to switch over.

Several things going on there all at once :) which makes it difficult to offer advice…. other than you can boot a 32bit installation with a 64bit kernel. My Linode has Ubuntu 12.04 32bit installed. To upgrade to the new platform, I set a 64bit kernel in the Linode manager. Runs perfectly. Not saying that CentOS will do the same.

CentOS 7 is certainly stable IMO. You need to ask on the Webmin mailing list about Webmin support for CentOS 7. Though I would think it's fully supported.

Spin up a new Linode, set it up and test it out. Once your happy, migrate your site(s), test some more, then swap IPs.

Could you at least READ before spamming, spammer?

I did a move from Centos 5 to 7 - the major change was that it now uses systemd. You'd do well to read up a little bit on that: https://access.redhat.com/documentation … stemd.html">https://access.redhat.com/documentation/en-US/RedHatEnterpriseLinux/7/html/SystemAdministratorsGuide/chap-ManagingServiceswithsystemd.html

Apache is now at version 2.4 which has changed some of its configuration syntax, but I think the old syntax is still supported. You might find that other applications (e.g., Postfix) have changed configuration syntax also. The other main thing I noticed is that chrony replaces ntp as the default time-setting daemon (you can install ntp if you have some special reason, but chrony seems to work fine with the provided settings).
