@JaredBusch

Perhaps this is offtopic, but what is the swappiness setting you are supposed to use? Would that be applicable to this article, or is that a more "general CentOS setup" setting?

Neither. It is not related to WordPress, web hosting or to CentOS directly. It's a memory setting that would be dependent on many factors, like the IOPS you have, the storage and memory that you have, how you want your disk used, how the disks are shared with other systems, how much disk capacity you have spare and so forth.

Isn't it one of the settings you normally always enable?

Or am I thinking about something else?

It's not enabling or disabling, it's setting it. The OS default is 60. Many cloud providers change this in their own defaults because it impacts other customers. On my cloud instances, I normally set to 10.

If this was a physical box or a one to one VM install (only VM on a host) then a swappiness of 60 is a good starting point.

I install Centos 7 Minimal on a Vultr VM, and the default was 30.

Going back through this today.

What did we ever decide on PHP 5.X versus 7.X

Since WordPress seems to be recommending the move to 7.X, is it reasonable and desired to install that instead? Even if it is not in the official repositories? (I am, just asking for future reference for others.)

I would install this on Fedora today. If you want to be on CentOS 7, then install the Remi repo and enable the PHP 7.1 repo.

That's two votes for Fedora,then. I know @scottalanmiller is also a fan.

Yes. I think it is in two parts. One for the stack then another for WP. Since one is standard without the other.

JaredBusch

Just use this guide but install Fedora instead of CentOS. You will get PHP 7

BRRABill

I've actually been playing around with @scottalanmiller's Salt writeups to do this.

But there is still a bunch to do from this guide as well.

I'm all about Fedora as well... even Fedora Desktop for personal use, moreso than Korora.

So make that 3 votes.

How are you getting logs into Elastic Stack or whatever you're using now?

Obsolesce

@jaredbusch said in Installing Wordpress on CentOS 7 Minimal:

setenforce permissive;

Setup SELinux permissions

semanage fcontext -a -t httpd_sys_content_t '/opt/yourdomain(/.*)?'
restorecon -R /opt/yourdomain
semanage fcontext -a -t httpd_sys_rw_content_t '/opt/yourdomain/wp-content(/.*)?'
restorecon -R /opt/yourdomain/wp-content

I run my servers with SELinux running in Enforcing mode, not permissive.

So if it's in enforcing, WordPress will not run correctly. Example, you can't update, and the Add Plugins page gives a connection error (it's because httpd can't write correctly due to selinux enforcing).

Instead of running SELinux in permissive system-wide, you can keep it in Enforcing mode, and issue the following command:

semanage permissive -a httpd_t

The reason I use that one instead of by directory, is because I don't know how to do that... well I do, but I didn't have time yet to see what all directories need to be written to for updating and plugins pages and such to work correctly. I'll add that here some other time when I get a chance to look in to it more.
