All I can say is 'WOW!" ... that's one messed up server - from typical AMP stacks on CentOS.
Purpose of these forums isn't how to install/admin/ an AMP stack, but Moodle. Really stretching the stated purpose of these forums - and free advice to boot - appreciated or not!
Some hints/clues for you (from what you have shared) ... just a few ...
Loaded: loaded (/etc/rc.d/init.d/httpd; bad; vendor preset: disabled)
Huh??!!! bad vendor preset????!!! Where in the world did you get httpd from - what repo? Uhhhhh ... don't answer that ... or even try to ... don't wanna know!
/etc/init.d/httpd: line 95: lynx: command not found
Lynx is a text based browser!!!! How did it get entered in the init.d of httpd ... the daemon for apache? In CentOS 7 there is no /etc/init.d/httpd ... 7 doesn't use the old but the new (that's a hint)
[root@moodle /]# netstat -tulpn | grep :80 returning ...
tcp6 0 0 :::443 :::* LISTEN 3053/httpd ... port 3053

And see it's really a CentOS 7 Guest OS on VM-Ware?
You can backup moodle code and moodledata using tar and archive those backups to another location.
MySQL appears to be running so you can use mysqldump to get an sql dump of the moodle DB. Then archive that off onto another location.
scp the backups off onto some other server.
Now the biggy ... 2 choices ...
Wipe out the VM Instance of CentOS 7 and start over with a fresh CentOS 7 this time keeping it simple. This might be best as it could be you tried what many have tried and failed to do ... upgrade a CentOS 6 in place to a CentOS 7. Reason I say that ... 'old mixed with new'.
OR - the more difficult road for you at present me thinks ...
Use yum and erase httpd, httpd-development and anything related ... which also might remove php drivers and php itself - dependencies.
Reboot server. Basically rebuild an AMP stack. Set that up with valid/working repos for things like PHP and test a static page ... don't forget your valid certs for https:// as well as a php info page.
Then restore your Moodle.
Too much for ya? Fine ... one time offer ... I'll do it for $15,000.00 US ...
$10,000.00 up front payable via PayPal and the remainder due when server is up. No work done until funds have been transferred - ie, the first $10,000.00 (that ought to price me out of the market, ya think?)
Opion: $5,000.00 US for direct Email support ... $2500.00 up front via PayPal. Condition ... you will not argue with what I tell you to do!
(that ought to price me out of the support market also, ya think?)
OR ... role up sleeves and find a tutorial on how to install an AMP stack on CentOS 7 ... properly.

No! The repeat above is NOT a mistake!
A Google search for that will find several good tutorials on how to do that ... might have to make minor adjustments.
Not being mean nor cruel nor impolite ... just 100% honest in remote assessmet/free support exchange of public posted info via a forum that shouldn't be used for such.
