This documentation is not applicable for Avalon 4 and above. Please see the one host (all-in-one) Manual Installation Instructions for current versions. |
This documentation is for Release 3.0.0. For the Release 1 version of this page, see v.81. For the Release 2 version of this page, see v.87. |
Intended as guidance for production environments with different hosts for most tasks, these instructions provide a recipe for building only the Matterhorn piece of an Avalon system from scratch on CentOS or Red Hat Enterprise Linux. Recipes for the other components for Avalon may be found here. Fedora (standalone), MySQL (standalone), Web (standalone), Solr (standalone), and Red5 (standalone).
Instructions for building every component on one host (all-in-on) please see here: Manual Installation Instructions.
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.
The default hostname is “avalon.dev”, so name the machine this and enter it into /etc/hosts
# hostname avalon.dev # cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 avalon.dev |
The Avalon Media System requires several ports to be open to client browsers.
Here are the port settings that will need to be configured:
| Port | Purpose | External? |
|---|---|---|
| 8080 | HTTP (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
If you're connected over ssh, it might kick you off. |
Save your script to /etc/sysconfig/avalon-iptables-config.sh, make it executable and run it.
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".
echo 0 > /selinux/enforce vim /etc/selinux/config #change the value of `SELINUX` from `enforcing` to `permissive` |
Create the NUL repository config file:
vim /etc/yum.repos.d/nul-public.repo |
Append the following code:
[nul_public] name=NUL Library Public RHEL repository baseurl=http://yumrepo-public.library.northwestern.edu/x86_64 enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-nul cost=150 |
Install and place the NUL GPG key in the proper location:
curl http://yumrepo-public.library.northwestern.edu/RPM-GPG-KEY-nul -o /etc/pki/rpm-gpg/RPM-GPG-KEY-nul |
Install development libraries and packages for building Ruby
yum groupinstall "Development Tools" yum install readline-devel zlib-devel libyaml-devel libffi-devel openssl-devel libxml2-devel libxslt-devel |
Install prerequisite packages using yum and the NUL-public repository
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 \ libva-devel libfaac-devel libvdpau-devel libstdc++-devel libvorbis-devel libvpx-devel \ mediainfo opencore-amr-devel opencv-devel openjpeg-devel openssl-devel schroedinger-devel \ speex-devel texi2html vo-aacenc-devel x264-devel xvidcore-devel yasm zlib-devel |
Install rpmdev-setuptree
yum install rpmdevtools |

Create a user for Matterhorn and then install Matterhorn
useradd matterhorn yum -y install java-1.6.0-sun wget https://github.com/avalonmediasystem/avalon-felix/archive/1.4.x.tar.gz tar xvf 1.4.x.tar.gz mv avalon-felix-1.4.x /usr/local/matterhorn wget https://raw.github.com/avalonmediasystem/config-files/master/matterhorn/matterhorn_init.sh mv matterhorn_init.sh /etc/init.d/matterhorn chmod +x /etc/init.d/matterhorn chown -R matterhorn:matterhorn /usr/local/matterhorn |
Add avalon user and create avalon directory.
useradd avalonuseradd red5 mkdir -p /var/www/avalonchown -R avalon:avalon /var/www/avalon |
Create and configure streaming directories.
mkdir -p /usr/local/red5/webapps/avalon/streamsmkdir /var/avalonmkdir -p /var/www/avalon/public/streamschown red5:avalon /usr/local/red5/webapps/avalon/streamschmod 0775 /usr/local/red5/webapps/avalon/streamsln -s /usr/local/red5/webapps/avalon/streams /var/avalon/rtmp_streams mkdir /var/avalon/hls_streamschown root:root /var/avalon/hls_streams/ln -s /var/avalon/hls_streams/ /var/www/avalon/public/streamschmod 0775 /var/avalon/hls_streams/ |
Download Matterhorn config and verify property values.
wget https://raw.github.com/avalonmediasystem/config-files/master/matterhorn/config.properties vim config.properties |
Change the server url port from 18080 to 8080org.opencastproject.server.url=http://localhost:8080 |
And verify the configuration of the streaming directories
org.opencastproject.streaming.directory=/var/avalon/rtmp_streams org.opencastproject.hls.directory=/var/avalon/hls_streams |
Move the config to the appropriate spot
mv config.properties /usr/local/matterhorn/etc/ |
Add matterhorn user to the avalon group.
usermod -G avalon matterhorn |
groupadd -r dropbox useradd -r avalondrop usermod -G dropbox avalon mkdir -p /var/avalon/dropbox chown avalondrop:dropbox /var/avalon/dropbox chmod 2775 /var/avalon/dropbox |

Restart SSH
service sshd restart |
Before you restart your Avalon server, you'll want to make sure all of the services necessary to run Avalon will start automatically after the restart. Run these commands once and you should be set:
chkconfig --level 345 sshd on chkconfig --level 345 matterhorn on |
