What @JaredBusch said +make sure DC2 is a global catalog before demoting DC1.
Regarding replication, as I don't like to wait I would use repadmin to be sure replication is completed instead of waintg for x business days.

@thwr
I have mine working out of CentOS 7 minimal with ssh/perl and ports 2500-5000 open. Veeam does not even need root or NFS for a Linux repository.
Be careful as Veeam copies and executes programs to /tmp and I had my /tmp partition with noexec; took me a while to figure it out.

As it may help someone else:
I just made a new installation of XO Community (xo-server 5.32.2, xo-web 5.32.1) and found a problem with the web interface not fully working. As I use nginx as a reverse SSL proxy and HTTP authenticator I needed a custom .config.yaml

It happens that the included sample.config.yaml is not ready to be used (it's a sample, I get it). The mounts: section does not include the required files to be served.
Mine, which is a default installation worked with:

  mounts:
    '/': '/opt/xen-orchestra/packages/xo-web/dist'

@dbeato
Shame on me for skipping that part, I lost about 1 hour. In my defense, their documentation is not consistent (so I was kind of lost).

• Here it is recommending packages/xo-server/.xo-server.yaml
• I remember having used packages/xo-server/.config.yaml
• Now I'm using /etc/xo-server/config.yaml per https://xen-orchestra.com/docs/configuration.html

Thank you!

@WrCombs
Now I'm intrigued. Can you do me a favor?
Please download http://www.alexnolan.net/software/dbf.htm and try to open a copy of one of those DBfs.

• If it works you will have your solution
• If it does not work, I will owe you one

@jmoore said in Standard Plugins for WordPress Sites:

disable xml-rpc

I protect xml-rpc and Admin from brute force attacks with some ConfigServer Security & Firewall (CSF) custom rules. Basically I instruct CSF/LFD to look for POST requests to xmlrpc.php & wp-login.php in the webserver log and block the source IPs after x failed attempts

@travisdh1 said in MailCow in Production Datacenter:

things randomly break.

I agree. I have avoided docker because some things do not seem reliable. And I have applied mailcow updates that break things that should not be broke: I mean what happens makes no sense.
On the other hand, I have moved mailcow from Debian to CentOS within short maintenance windows and docker has eased the process.
Now that I think about it, mailcow is probably the only docker based deployment I have and probably will for some time

Migrating a medium sized WordPress site to a new server. I don't like WP

I would say:
lsyncd for user mode, simple, rsync based solution: https://github.com/axkibe/lsyncd
csync2 for multi-host synchronization with conflict detection: https://github.com/LINBIT/csync2
MARS for a kernel side solution (DRBD alternative): http://schoebel.github.io/mars/

Oh, yes: Learn from a good source.
PHP "was" badly designed. PHP 7 has more sanity. Quoting someone on the internet: "Languages like Python or Ruby were designed, PHP just happened"

@EddieJennings
For standalone WordPress hosting I usually use Centmin Mod option 22. It is fast and rock solid

In NOARCHIVELOG mode the database must be shut down before you can back it up. I recommend you to change the database mode to ARCHIVELOG so you can perform an online backup.

There are many documents and blog posts about it, but this may help you:

@tim_g
Some editors handle the TODO's very well when prefixed like this:
//TODO: whatever ...
/TODO: whatever .../
Thay way you can have a look of all of your pending stuff in one place

The editor in the picture is PhpStorm

@tonyshowoff
Absolutely. I am slowly "forcing" the move from cPanel to Linux without a control Panel. So far, the sites moved are working very well

But what Backup system/software are you using?

I know that the question is not for me but... That is an interesting one. I have used a few (from BackupExec to Veeam) and of course, Oracle's RMAN. Oracle database in a beast and in my experience it doesn't matter what backup software you use; you need play by their rules.

In this case, it seems like the backup software is just trying to use Oracle's VSS writer to backup. I have done that and recovered databases like that, but in ARCHIVELOG mode. In this case the VSS writer is chocking on NOARCHIVELOG.

In the end, I usually have 2 backups:

• RMAN
• Something else that backs up at least the RMAN backups; sometimes in addition to its own backup.

Call me paranoid.

We are developing an Student information System for a customer. Pinegrow + VS Code are a nice combination

@jaredbusch @black3dynamite
Perhaps I didn't update config.php!
I will check later, thank you

Jokes aside, Mailcow works very well and the author's support is awesome; this one I use and recommend.
I would say that Mailcheap's web site has lots of information, but that's me. I don't use it as I host my own email (besides using Office 365/G Suite/others depending on the client). I just seemed to me that it checked all @thwr needs while being recommended by people I trust.
$0.02

I also use Cyberarms Intrusion Detection.It works well
