Add nginx user and let it own nginx stuff

useradd -M -s /bin/nologin nginx
chown -R nginx:nginx /etc/nginx /var/log/nginx 

Start nginx

chmod +x /etc/init.d/nginx
service nginx start

Avalon config should be updated to be compatible with Nginx:

streaming:
  server: :nginx
  http_base: 'http://localhost:8980/avalon'
  content_path: '/var/avalon/derivatives'

FFmpeg

Installation prerequisites

Install prerequisite packages using yum and the Avalon repository (note: mediainfo is pinned to 0.7.61-1 because of a bug with time fragment formatting in most recent version 0.7.87-1 in epel):

yum install SDL-devel a52dec-devel bzip2-devel faad2-devel freetype-devel frei0r-plugins-devel \
	gsm-devel imlib2-devel lame-devel libdc1394-devel libraw1394-devel librtmp-devel libtheora-devel \

	speex-devel texi2html vo-aacenc-devel x264-devel xvidcore-devel yasm zlib-devel

Install rpmdev-setuptree

yum install rpmdevtools

Install ffmpeg srpm

The following commands need to run under a user other than root. Change to another user to continue.

su - someuser

Run the ffmpeg installer

rpmdev-setuptree

# Build ffmpeg binary as non-root and install as root

rpmbuild -bb rpmbuild/SPECS/ffmpeg24.spec

Log back in as root and finish the install.

su - root
rpm -ivh /home/someuser/rpmbuild/RPMS/x86_64/ffmpeg-*.rpm

You can also build a more modern ffmpeg from source, but not all versions work. Version 3.1 is known to work - check out the release/3.1 branch and build from there. If your modern ffmpeg uses fdk_aac instead of libfaac, adjust Avalon config/ffmpeg_presets.xml accordingly.

HTTPD

Install and start the httpd service.

yum install httpd
service httpd start

With newer httpd you may need to in /etc/httpd/conf.d/10-mod_rewrite.conf, replace RewriteLock line with Mutex sem

Apache Passenger and Ruby

Change current user to avalon then install RVM and ruby 2.4.1

su - root
yum install sqlite-devel
su - avalon
curl -L https://get.rvm.io | bash -s stable --ruby=2.4.1

Source the RVM shell (as avalon user) or close the terminal and open it back up.

source /home/avalon/.rvm/scripts/rvm
rvm use 2.4.1

Install Passenger via Gem (as avalon user)

gem install passenger

Check to make sure passenger installed in the expected location (as avalon user)

$ passenger-config --root
/home/avalon/.rvm/gems/ruby-2.4.1/gems/passenger-5.0.17

Install Passenger apache module requirements (as root)

su - root
yum install curl-devel httpd httpd-devel apr-devel apr-util-devel

Build passenger for your version of Apache and Ruby (as avalon user)

su - avalon
passenger-install-apache2-module #copy the suggested Apache configuration file settings for later

Create an apache configuration file (as root)

su - root
vim /etc/httpd/conf.d/passenger.conf

Example contents of /etc/httpd/conf.d/passenger.conf, which may need to be changed based off of the current version of ruby and passenger:

LoadModule passenger_module /home/avalon/.rvm/gems/ruby-2.4.1/gems/passenger-5.0.17/buildout/apache2/mod_passenger.so
<IfModule passenger_module>

vim /etc/httpd/conf.d/20-avalon.conf

In 20-avalon.conf add this line inside the VirtualHost tag:

RailsEnv developmentproduction

If using SSL, the following fix should be added to address BEAST, POODLE, RC4 issues (after the SSLEngine on)

...

Restart apache.  With apache running, check passenger-status

servicesystemctl start httpd restart
su - avalon
which passenger-status
#> ~/.rvm/gems/ruby-2.4.1/bin/passenger-status

Avalon

Grab Avalon code from github

cdsu - ~root
git clone githttps://github.com/avalonmediasystem/avalon.git
cd avalon
git checkout master #make sure you are in the master branch (should be by default)
su - root
chown avalon:avalon /var/www/avalon/public/
suchown - avalon:avalon mv public/* /var/www/avalon/public/
rmdir public
mv  * /var/www/avalon/

Configure Avalon 

As of 6.3, Avalon is using the flexible and increasingly popular Config gem. Default settings for Avalon now live at config/settings.yml, which should not be altered. Any custom config should be placed in config/settings/<environment>.local.yml which will selectively override the default values.
