OpenStack: Install Icehouse on Centos 6.5

• Based on the instructions here: http://docs.openstack.org/icehouse/install-guide/install/yum/content/
• 3 system setup, each with Centos6.5 minimal and both 1GB interfaces plugged in (172.28 eth0 / 192.168.0 eth1)

Initial Setup

• Setup networking on eth0 and name the hosts as follows (these names are used for the configuration later on)

172.28.80.0	x8-0 	network
172.28.80.1	x8-1 	compute1
172.28.80.2	x8-2 	controller

• Although not needed on centos6.5, disable firewalld and NetworkManager
• Make sure all hosts can ping the outside world (ping openstack.org)
• Setup ntpd and set the correct TZ

chkconfig ntpd on
service ntpd start
# then add the following line to the ~/.bashrc
TZ='Europe/London'; export TZ

Setup the DB on the Controller

• Setup the DB on the Controller node

yum install mysql mysql-server MySQL-python

• Edit the /etc/my.cnf file, add the following in the [mysqld] section

bind-address = 172.28.80.2
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8

• Restart the DB and setup security

service mysqld start
chkconfig mysqld on
mysql_install_db
mysql_secure_installation # go with defaults for everything unless you have a good excuse not to

• On all other nodes, compute/network

yum install MySQL-python
