Ready the Installation Environment

Install EPEL

Code Block
rpm -ivh http://linux.mirrors.es.net/fedora-epel/6/i386/epel-release-6-8.noarch.rpm

This package has libyaml-devel which is required by ruby and not provided by Redhat.

Make sure a valid hostname is resolvable

The default hostname is “avalon.dev”, so name the machine this and enter it into /etc/hosts

Code Block
# hostname
avalon.dev
# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 avalon.dev

...

Here are the port settings that will need to be configured:

PortPurposeExternal?
80HTTP (Avalon)Yes
1935RTMP (red5)Yes5080
8983HTTP (
red5
Solr)No
8983
8984HTTP (Fedora
/Solr
)No
18080
8080HTTP (Matterhorn)Yes

 


The preferred method is to create a shell script that will do the work for you. Here is an example script that you should look through and customize as needed: avalon-iptables-config.sh

...

Code Block
chmod +x /etc/sysconfig/avalon-iptables-config.sh
/etc/sysconfig/avalon-iptables-config.sh

 

If you run into connection issues you can disable the iptables, by running "service iptables stop". This will completely drop your firewall. When finished troubleshooting run "service iptables start".

...

Code Block
echo 0 > /selinux/enforce 
vim /etc/selinux/config #change the value of `SELINUX` from `enforcing` to `permissive`

...


Info
titleYou may have to disable SELinux completely if there's Passenger installation problem
vim /etc/selinux/config #change the value of `SELINUX` to `disabled`

Install EPEL

This package has libyaml-devel which is required by ruby and not provided by Redhat.

Code Block
rpm -ivh http://linux.mirrors.es.net/fedora-epel/6/i386/epel-release-6-8.noarch.rpm


Add the Avalon repository 
Anchor

...

Create the NUL repository Avalon repository config file:

Code Block
vim /etc/yum.repos.d/nulavalon-public.repo

Append the following code:

Code Block
[nulavalon_public]
name=NULAvalon Library Public RHEL repository
baseurl=http://yumrepo-publicrepo.libraryavalonmediasystem.northwestern.eduorg/x86_64
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-nulavalon
cost=150

Install and place the NUL Avalon GPG key in the proper location:

Code Block
curl http://yumrepo-publicrepo.libraryavalonmediasystem.northwestern.eduorg/RPM-GPG-KEY-nulavalon -o /etc/pki/rpm-gpg/RPM-GPG-KEY-nulavalon

Install development libraries and packages for building Ruby

Code Block

yum install readline-devel zlib-devel libyaml-devel libffi-devel openssl-devel libxml2-devel libxslt-devel cmake

Install Java 8

Code Block
yum install java-1.8.0-openjdk

Main Components

Fedora Commons Repository

Tomcat

Install Apache Tomcat with the nulrepo-public repository configured and enabled.Fedora runs as a webapp in Tomcat

Install Apache Tomcat 

Code Block
titleRHEL 7
yum install tomcat
service tomcat start
vim /usretc/local/tomcat/conf/server.xml

on line 70, change the Tomcat connector port from 8080 to 8983:

Code Block
<Connector port="8983" protocol="HTTP/1.1" #line 71, change the Tomcat connector port from 8080 to 8984

Add Tomcat manager user

By default, no user has access to the Tomcat Manager App.  

...

Define a user in /etc/tomcat/tomcat-users.xml

...

Define a user in tomcat-users.xml with  with access to the manager-gui role. Below is a very basic example.

Code Block
<tomcat-users>
  <role rolename="manager-gui"/>
  <user username="admin" password="tomcat<insert strong password here>" roles="manager-gui"/>
</tomcat-users>

Configure Tomcat for Fedora

Append the following to /etc/sysconfig/tomcat

Code Block
JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.modeshape.configuration=classpath:/config/file-simple/repository.json -Dfcrepo.home=/var/avalon/fedora/"

Restart Tomcat

Code Block
service tomcat restart

Download and run the fcrepo installer

Code Block
mkdir -p /var/avalon/fedora
chown tomcat:tomcat /var/avalon/fedora
wget https://github.com/fcrepo4/fcrepo4/releases/download/fcrepo-4.7.3/fcrepo-webapp-4.7.3.war -O /usr/share/tomcat/webapps/fedora4.war

See if you can log in to the manager app access Fedora's REST interface at http://<server host name>:89838984/managerfedora4/htmlrest

Try it out on your local machine and on another machine. If you can't reach the app from another machine, your your iptables might  might need to be changed to allow access. If Fedora is not up, check the tomcat logs in /var/log/tomcat/. Catalina.out and localhost.<date>.log usually provide the best information.

Solr

Avalon makes use of Solr through the Blacklight gem for faceting and relevance-based searching.

Install prerequisites

Code Block
yum install lsof

Download the solr tarball and

...

run the installation script

Download Solr from http://wwwarchive.apache.org/dyndist/closer.cgi/lucene/solr/4.2.0

Code Block
wget http://archive.apache.org/dist/lucene/solr/6.4.2.0/solr-6.4.2.0.tgz
tar xvfxzf solr-6.4.2.0.tgz mv solr-6.4.2.0 /usrbin/local/solr
cd /usr/local/solr/dist/
cp solr-4.2.0.war /usr/local/tomcat/webapps/solr.war
mv solr-4.2.0.war /usr/local/solr/solr.war

Add XML configurations

Edit /usr/local/tomcat/conf/Catalina/localhost/solr.xml and add

Code Block
<Context docBase="/usr/local/solr/solr.war" debug="0" crossContext="true">
 <Environment name="solr/home" type="java.lang.String" value="/usr/local/solr" override="true"/>
</Context>

Edit /usr/local/solr/solr.xml and insert

Code Block
<?xml version="1.0" encoding="UTF-8" ?>
  <solr persistent="true">
    <cores defaultCoreName="avalon" adminPath="/admin/cores" zkClientTimeout="${zkClientTimeout:15000}" hostPort="8983" hostContext="solr">
    <core instanceDir="avalon/" name="avalon"/>
  </cores>
</solr>

Download and Install Avalon specific Solr files from github

Code Block
mkdir /usr/local/solr/lib
mv /usr/local/solr/dist/* /usr/local/solr/lib/
mv /usr/local/solr/contrib /usr/local/solr/lib/
 
wget https://github.com/avalonmediasystem/puppet-solr/archive/master.zip
unzip master
mv puppet-solr-master/files/avalon /usr/local/solr
chown -R tomcat7:tomcat /usr/local/solr/
chown -R tomcat7:tomcat /usr/local/tomcat
service tomcat restartinstall_solr_service.sh --strip-components=2
bash ./install_solr_service.sh solr-6.4.2.tgz

By default, the script extracts the distribution archive into /opt, configures Solr to write files into /var/solr, and runs Solr as the solr user. Follow the linked guide if you wish to change these defaults.

Create Avalon core for Solr

Code Block
mkdir -p /tmp/avalon_solr/
wget https://raw.githubusercontent.com/avalonmediasystem/avalon/master/solr/config/solrconfig.xml -O /tmp/avalon_solr/solrconfig.xml
wget https://raw.githubusercontent.com/avalonmediasystem/avalon/master/solr/config/schema.xml -O /tmp/avalon_solr/schema.xml
su solr # Needs to run as solr user
/opt/solr/bin/solr create_core -c avalon -d /tmp/avalon_solr
exit

If you have successfully installed Solr you should be able to access the dashboard page at http://<server host name>:8983/solr

If you can't access the dashboard, check the tomcat logs in /usr/local/tomcat/logs/. Catalina.out and localhost.<date>.log usually provide the best information.

MySQL

Instructions on how to manually start/stop Solr: https://cwiki.apache.org/confluence/display/solr/Running+Solr

MySQL

Info
titleMariaDB

MariaDB is now the default database system for CentOS/RHEL7. Feel free to change Mysql below to MariaDB

Avalon uses MySQL for storing search queries, user data and roles, and as a back end for asynchronously sending requests to Matterhorn.

Red5 Media Server

Red5 is an open source alternative to Adobe Media Server. If using the Adobe Media Server you can skip to the next step.

Create a red5 user.

Code Block
useradd red5

Download and install Red5.

Code Block
wget http://red5.org/downloads/red5/1_0_1/red5-1.0.1.tar.gz
tar xvf red5-1.0.1.tar.gz
mv red5-server-1.0 /usr/local/red5

Download the init script and add it to the init.d directory.

Code Block
wget https://raw.github.com/avalonmediasystem/avalon-installer/master/modules/red5/templates/red5_init_script.erb -O red5_init_script.sh
mv red5_init_script.sh /etc/rc.d/init.d/red5

Give Red5 permissions to the red5 directory and the init script.

Code Block
chown -R red5:red5 /usr/local/red5
chmod +x /etc/rc.d/init.d/red5

Media Streaming Server

Warning

Nginx replaces Red5 as the default streaming server since Avalon 6.3. With the upgrade to MediaElementjs 4, we now rely completely on HLS.

An HLS-enabled server like Wowza, Adobe Media Server (commercial) or Nginx + the HLS module (open-source) can take an mp4 created from distribute-streaming and stream it on the fly.

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.

Properly formatted environment variables can also override Avalon settings. For example, SETTINGS__REDIS__HOST will override

redis:
  host:

A list of config values can be found at Configuration Files#config/settings.yml


Warning

If using vim with default settings and pasting the the code below, it will automatically comment out the last line. To prevent that, enable paste using the command :set paste and then use just ctrl+shift+v instead of going into insert mode.

Create /var/www/avalon/config/setup_load_paths.rb and add:

Code Block
if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')
   begin
     gems_path = ENV['MY_RUBY_HOME'].split(/@/)[0].sub(/rubies/,'gems')
     ENV['GEM_PATH'] = "#{gems_path}:#{gems_path}@global"
     require 'rvm'
     RVM.use_from_path! File.dirname(File.dirname(__FILE__))
   rescue LoadError
     raise "RVM gem is currently unavailable."
   end
 end
 # If you're not using Bundler at all, remove lines bellow
 ENV ENV['BUNDLE_GEMFILE'] = File.expand_path('../Gemfile', File.dirname(__FILE__))
 require 'bundler/setup'
