Installguide arch-neutron.png

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

Install the OpenStack Software

  • Install this on all server (control, network, compute)
yum -y install yum-plugin-priorities
# bug fix, seems to remove the need for the above - but anyway: 
sed -i "s/enabled = 1/enabled = 0/g" /etc/yum/pluginconf.d/priorities.conf 
yum -y install http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-3.noarch.rpm
yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum -y install openstack-utils
yum -y install openstack-selinux
# yum upgrade / reboot if you can be arsed

Install the Messaging Server

  • Install on the control node (but can be installed anywhere - the eg. has everything on the control node)
yum -y install qpid-cpp-server
sed -i "s/auth=yes/auth=no/g" /etc/qpidd.conf 
service qpidd start
chkconfig qpidd on

Install and Configure the Identity Service (Keystone)

  • Install on the control node
yum -y install openstack-keystone python-keystoneclient
openstack-config --set /etc/keystone/keystone.conf database connection mysql://keystone:password@controller/keystone
  • Setup a keystone DB
$ mysql -u root -p
mysql> CREATE DATABASE keystone;
mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost'   IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'   IDENTIFIED BY 'password';
mysql> exit
  • Do lots more stuff
# create the DB tables
su -s /bin/sh -c "keystone-manage db_sync" keystone
# setup a token
ADMIN_TOKEN=$(openssl rand -hex 10)
echo $ADMIN_TOKEN
# Note admin token as you will need later on
openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token $ADMIN_TOKEN
# setup pki keys
keystone-manage pki_setup --keystone-user keystone --keystone-group keystone
chown -R keystone:keystone /etc/keystone/ssl
chmod -R o-rwx /etc/keystone/ssl
  • Start the service and enable on boot
service openstack-keystone start
chkconfig openstack-keystone on
  • Optional: Purge the tokens every hour as they are typically kept indefinitely.
(crontab -l -u keystone 2>&1 | grep -q token_flush) || \
echo '@hourly /usr/bin/keystone-manage token_flush >/var/log/keystone/keystone-tokenflush.log 2>&1' >> /var/spool/cron/keystone
  • Define users / tenants / roles
# Assuming your still in the same shell as above 
export OS_SERVICE_TOKEN=$ADMIN_TOKEN
export OS_SERVICE_ENDPOINT=http://controller:35357/v2.0
  • Create the admin user
keystone user-create --name=admin --pass=password --email=david.power@boston.co.uk
keystone role-create --name=admin
keystone tenant-create --name=admin --description="Admin Tenant"
keystone user-role-add --user=admin --tenant=admin --role=admin
keystone user-role-add --user=admin --role=_member_ --tenant=admin
  • Create the normal user
keystone user-create --name=demo --pass=password --email=david.power@boston.co.uk
keystone tenant-create --name=demo --description="Demo Tenant"
keystone user-role-add --user=demo --role=_member_ --tenant=demo
  • Create the service user
keystone tenant-create --name=service --description="Service Tenant"
  • Define services and APIs endpoints
keystone service-create --name=keystone --type=identity --description="OpenStack Identity"
keystone endpoint-create \
  --service-id=$(keystone service-list | awk '/ identity / {print $2}') \
  --publicurl=http://controller:5000/v2.0 \
  --internalurl=http://controller:5000/v2.0 \
  --adminurl=http://controller:35357/v2.0
  • Verify the Identity service installation
unset OS_SERVICE_TOKEN OS_SERVICE_ENDPOINT
keystone --os-username=admin --os-password=password --os-auth-url=http://controller:35357/v2.0 token-get
keystone --os-username=admin --os-password=password --os-tenant-name=admin --os-auth-url=http://controller:35357/v2.0 token-get
  • Setup an rc file for these settings
[root@x8-2 ~]# cat admin-openrc.sh 
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://controller:35357/v2.0
# source
source admin-openrc.sh
keystone token-get
# now we can run keystone commands
[root@x8-2 ~]# keystone user-list 
+----------------------------------+-------+---------+--------------------------+

+----------------------------------+----------+----------------------------------+----------------------------------+
  • Setup the demo user rc file (for later)

export OS_PASSWORD=password
export OS_TENANT_NAME=demo
export OS_AUTH_URL=http://controller:35357/v2.0
