Installing Wordpress on CentOS 7 Minimal
-
Updated the instrucitons a bit to make the MySQL setup non interactive and fixed a missing bit of info for the httpd.conf.
-
Thanks to @BRRABill it looks like I missed some SELinux issues.
Instructions updated, but this is what I needed to resolve his issues so far. He just installed, so maybe more updates to come
yum install -y policycoreutils-python 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 -
One other thing @JaredBusch and I discussed was the location in /opt and opposed to /var
In theory, it should not matter.
-
BTW, thanks for the writeup. Very good job.

@scottalanmiller there was a discussion in a thread here a couple years ago around using
/opt/for wordpress installs. but I cannot find it. I think there was a reasoning from someone in there for that location. -

Looking into things I found this link. Granted this is about packaging for RPM but still.
https://fedoraproject.org/wiki/Packaging:Guidelines#Web_ApplicationsWeb Applications
Web applications packaged in Fedora should put their content into /usr/share/%{name} and NOT into /var/www/. This is done because:
- /var is supposed to contain variable data files and logs. /usr/share is much more appropriate for this.
- Many users already have content in /var/www, and we do not want any Fedora package to step on top of that.
- /var/www is no longer specified by the Filesystem Hierarchy Standard

Hmmm... point two I understand. It's already in use. But it was always in /var specifically because it is variable data, that's where upload caches and stuff go.
No idea about the hierarchy.

Looks like I got the /opt thing from you. Your LEMP challenge used /opt/wordpress.
https://mangolassi.it/topic/1082/the-wordpress-on-centos-lemp-challengeNow I know there was a subsequent discussion somewhere on ML about /opt, I just cannot find it.

I have a feeling that it was or is the nginx default directory.

I ask about it after seing your guide and you choosing /opt for the instalation

And as you can see from my link above, @scottalanmiller's answer in your thread is not helpful. He simply stated standards. But what standard is the question.

No, you continually reference /opt as the directory to use for 3rd party applications.
It I guess the better question is whether or not web apps like this are considered third party applications or something to put in webroot. A Google site search of this site and the term /opt returns many threads with directions from you installing things to /opt.
-
He also has said that /var is the only place data should be stored.
Hmmmmm.........
Come on @scottalanmiller let's get it figured out!
-
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?

generally he says he always sets it to 30 or something like that in other threads.

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.
