Revision as of 18:56, 24 May 2013

Fedora 19 is when OpenShift Origin first became a feature.

This page is here to show how to setup OpenShift Origin on Fedora 19 using the packages in Fedora, as opposed to the packages published from upstream. These steps are written out to be done by hand. Yes, people can script and/or puppetize these steps. But these are written out so that people can see, and fine tune them.

Goal: By the end of this, you should have two machines. A broker machine, and one node machine. You should be able to create applications, that will be put on the node machine. You should be able to check the status of those applications. You should be able to point your web browser to the URL of those applications.

Note: There is no web console in Fedora 19. That will be in Fedora 20.

These instructions were created most from the following two places.

Initial Setup of Broker and Node Machines

ON BOTH BROKER AND NODE

# Start with a Fedora 19 minimal install
yum -y update
# avoid clock skew
yum -y install ntp
/bin/systemctl enable ntpd.service
/bin/systemctl start  ntpd.service

Setup and Configure Broker

export DOMAIN="example.com"
export BROKERIP="$(nm-tool | grep Address | grep -v HW | awk '{print $2}')"
export BROKERNAME="broker.example.com"

Broker: Bind DNS

Configure the BROKER DHCP client and hostname

echo "prepend domain-name-servers **your broker ip address**;" >> /etc/dhcp/dhclient-eth0.conf echo "supersede host-name \"broker\";" >> /etc/dhcp/dhclient-eth0.conf echo "supersede domain-name \"example.com\";" >> /etc/dhcp/dhclient-eth0.conf

echo "broker.example.com" > /etc/hostname

Installing and configuring MongoDB

yum -y install mongodb-server

vi /etc/mongodb.conf

  1. Uncomment auth = true
  2. Add smallfiles = true

/usr/bin/systemctl enable mongod.service /usr/bin/systemctl status mongod.service /usr/bin/systemctl start mongod.service /usr/bin/systemctl status mongod.service

  1. Testing

mongo > show dbs > exit

Installing and configuring QPID

  1. Activemq on F19 isn't ready for production. When it is, we'll use that
  2. For now let's use QPID with mcollective.

yum install mcollective-qpid-plugin qpid-cpp-server firewall-cmd --add-port=5672/tcp firewall-cmd --permanent --add-port=5672/tcp firewall-cmd --list-all

/usr/bin/systemctl enable qpidd.service /usr/bin/systemctl start qpidd.service /usr/bin/systemctl status qpidd.service

Installing and configuring MCollective client (QPID)

yum -y install mcollective-client mv /etc/mcollective/client.cfg /etc/mcollective/client.cfg.orig

cat <<EOF > /etc/mcollective/client.cfg topicprefix = /topic/ main_collective = mcollective collectives = mcollective libdir = /usr/libexec/mcollective loglevel = debug logfile = /var/log/mcollective-client.log

  1. Plugins

securityprovider = psk plugin.psk = unset connector = qpid plugin.qpid.host=broker.example.com plugin.qpid.secure=false plugin.qpid.timeout=5

  1. Facts

factsource = yaml plugin.yaml = /etc/mcollective/facts.yaml EOF

Installing and configuring the broker application

  1. When mcollective was updated to 2.2.3 it created a conflict with one of our components.
  2. We are working on fixing the conflict, but until then, do the following.

yumdownloader openshift-origin-msg-common rpm -Uvh openshift-origin-msg-common-1.4.1-1.fc19.noarch.rpm --nodeps --force

yum -y install openshift-origin-broker openshift-origin-broker-util rubygem-openshift-origin-auth-remote-user rubygem-openshift-origin-msg-broker-mcollective rubygem-openshift-origin-dns-bind

sed -i -e "s/ServerName .*$/ServerName broker.example.com/" /etc/httpd/conf.d/000002_openshift_origin_broker_servername.conf cat /etc/httpd/conf.d/000002_openshift_origin_broker_servername.conf

/usr/bin/systemctl enable httpd.service /usr/bin/systemctl enable ntpd.service /usr/bin/systemctl enable sshd.service

firewall-cmd --add-service=ssh firewall-cmd --add-service=http firewall-cmd --add-service=https firewall-cmd --permanent --add-service=ssh firewall-cmd --permanent --add-service=http firewall-cmd --permanent --add-service=https firewall-cmd --list-all

vi /etc/openshift/broker.conf

  1. Might not have to do anything

CLOUD_DOMAIN="example.com" VALID_GEAR_SIZES="small,medium"

Configuring the broker plugins and MongoDB user accounts

  1. pushd /usr/share/selinux/packages/rubygem-openshift-origin-dns-bind/ && make -f /usr/share/selinux/devel/Makefile ; popd
  2. semodule -i /usr/share/selinux/packages/rubygem-openshift-origin-dns-bind/dhcpnamedforward.pp

  1. Don't forget your password. <demo password>

cat /etc/openshift/htpasswd

grep MONGO /etc/openshift/broker.conf mongo openshift_broker_dev --eval 'db.addUser("openshift", "mooo")'

  1. If you are going to change the username and/or password, change broker.conf

yum -y install rubygem-psych cd /var/www/openshift/broker

  1. This is being fixed, but for now do the following

vi Gemfile

  1. remove minitest version
  2. add gem 'psych'

gem install mongoid bundle --local

/usr/bin/systemctl enable openshift-broker.service /usr/bin/systemctl start httpd.service /usr/bin/systemctl start openshift-broker.service /usr/bin/systemctl status openshift-broker.service
