The hardware we’ll be using is based on the following specifications:
- 1 x MAAS Rack with Region controller: 8GB RAM, 2 CPUs, 1 NIC, 40GB storage
- 1 x Juju node: 4GB RAM, 2 CPUs, 1 NIC, 40GB storage
- 4 x OpenStack cloud nodes: 8GB RAM, 2 CPUs, 2 NICs, 80GB storage
Installing MAAS
root@maas:~#
add-apt-repository ppa:maas/stable
root@maas:~#
apt-get -y update;apt-get -y upgrade;apt-get -y dist-upgrade
root@maas:~#
reboot
root@maas:~#
cat /etc/lsb-release;uname -r
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04

DISTRIB_DESCRIPTION="Ubuntu
16.04.3 LTS"
4.4.0-101-generic
root@maas:~#
apt-get -y update;apt-get -y install maas
NOTE: When asked for the Ubuntu MAAS API address, double check the detected URL uses eth0’s (external) IP address: http://10.10.2.37 /MAAS/. You can later change this by running:
root@maas:~# dpkg-reconfigure maas-rack-controller
Also, double check that running below command shows the IP of management interface same as the MAAS url.
root@maas:~# sudo dpkg-reconfigure maas-region-controller
root@maas:~# maas createadmin --username=maasadmin --password='maas@123' --email=maasadmin@maas
A final question will ask whether you want to import SSH keys. MAAS uses the public SSH key of a user to manage and secure access to deployed nodes, just as you might with managed servers or remote machines. Press Enter to skip this as we’ll do this from the web UI in the next step.
root@maas:~# maas-region apikey --username=admin > api_key
root@maas:~# maas login admin http://10.10.2.37:5240/MAAS/api/2.0 - < api_key
You are now logged in to the MAAS server at
http://10.10.2.37:5240/MAAS/api/2.0/ with the profile name 'admin'.
For help with the available commands, try:
maas admin --help
A handy shell script, say maas-login.sh, is provided:
#!/bin/sh
PROFILE=admin
API_KEY_FILE= /root/api_key
API_SERVER=10.10.2.37
MAAS_URL=http://$API_SERVER/MAAS/api/2.0
maas login $PROFILE $MAAS_URL - < $API_KEY_FILE
Once you are done with the CLI you can log out from the given profile, flushing the stored credentials.
root@maas:~# maas logout admin
Use this url to login to MAAS console. http://10.10.2.37:5240/MAAS
In the intro page enter domain name, dns forwarder for name resolution if required proxy ip for syncing images and then select required ubuntu release.
Keys: You
can conveniently import your public SSH key(s) from both Launchpad and Github
by entering your user id for these services. To add a local public key file,
usually HOME/ssh/id_rsa.pub, select Upload and paste file contents into the box
that appears. Click Import to fix the setting.
If you need
to generate a local SSH public/private key pair, type ssh-keygen -t rsa from
the Linux account you’ll control MAAS from, and when asked, leave the
passphrase blank.
maasadmin@maas:~$
cat /home/maasadmin/.ssh/id_rsa.pub
Manually
update the above key in the keys field and click import. Adding SSH keys
completes this initial MAAS configuration. Click Go to the dashboard to move to
the MAAS dashboard and the device discovery process
In subnets tab click on first subnet and provide dhcp range for assigning ip to other nodes for pxe boot.
In settings tab
Global Kernel Parameters field enter below values
net.ifnames=0 biosdevname=0
Proxy:
http://10.10.1.16:8080
DNS:
10.10.2.55
Storage:
LVM layout
Now lets discover the nodes. Select first boot as network boot in remaining server and reboot. The servers will get booted in pxe and adds as node in MAAS server. Rename the nodes as required and select all then give commission. Click the nodes which has 2 nic cards and make sure second interface shows subnet address and ip address as unconfigured.
Now our MAAS is done. Lets fire up confure-up and configure openstack nodes.
My environment is beyond proxy so i have excluded entire subnet in no-proxy so proxy will not be used for internal connectivity.
Take putty session of MAAS server:
#conjure-up --http-proxy "http://10.10.1.16:8080" --apt-proxy "http://10.10.1.16:8080" --apt-https-proxy "http://10.10.1.16:8080" --https-proxy "http://10.10.1.16:8080" --no-proxy "localhost,127.0.0.1,10.10.2.1,10.10.2.2,10.10.2.3,10.10.2.4,10.10.2.5,10.10.2.6,10.10.2.7,10.10.2.8,10.10.2.9,10.10.2.10,10.10.2.11,10.10.2.12,10.10.2.13,10.10.2.14,10.10.2.15,10.10.2.16,10.10.2.17,10.10.2333.18,10.10.2.19,10.10.2.20,10.10.2.21,10.10.2.22,10.10.2.23,10.10.2.24,10.10.2.25,10.10.2.26,10.10.2.27,10.10.2.28,10.10.2.29,10.10.2.30,10.10.2.31,10.10.2.32,10.10.2.33,10.10.2.34,10.10.2.35,10.10.2.36,10.10.2.37,10.10.2.38,10.10.2.39,10.10.2.40,10.10.2.41,10.10.2.42,10.10.2.43,10.10.2.44,10.10.2.45,10.10.2.46,10.10.2.47,10.10.2.48,10.10.2.49,10.10.2.50,10.10.2.51,10.10.2.52,10.10.2.53,10.10.2.54,10.10.2.55,10.10.2.56,10.10.2.57,10.10.2.58,10.10.2.59,10.10.2.60,10.10.2.61,10.10.2.62,10.10.2.63,10.10.2.64,10.10.2.65,10.10.2.66,10.10.2.67,10.10.2.68,10.10.2.69,10.10.2.70,10.10.2.71,10.10.2.72,10.10.2.73,10.10.2.74,10.10.2.75,10.10.2.76,10.10.2.77,10.10.2.78,10.10.2.79,10.10.2.80,10.10.2.81,10.10.2.82,10.10.2.83,10.10.2.84,10.10.2.85,10.10.2.86,10.10.2.87,10.10.2.88,10.10.2.89,10.10.2.90,10.10.2.91,10.10.2.92,10.10.2.93,10.10.2.94,10.10.2.95,10.10.2.96,10.10.2.97,10.10.2.98,10.10.2.99,10.10.2.100,10.10.2.101,10.10.2.102,10.10.2.103,10.10.2.104,10.10.2.105,10.10.2.106,10.10.2.107,10.10.2.108,10.10.2.109,10.10.2.110,10.10.2.111,10.10.2.112,10.10.2.113,10.10.2.114,10.10.2.115,10.10.2.116,10.10.2.117,10.10.2.118,10.10.2.119,10.10.2.120,10.10.2.121,10.10.2.122,10.10.2.123,10.10.2.124,10.10.2.125,10.10.2.126,10.10.2.127,10.10.2.128,10.10.2.129,10.10.2.130,10.10.2.131,10.10.2.132,10.10.2.133,10.10.2.134,10.10.2.135,10.10.2.136,10.10.2.137,10.10.2.138,10.10.2.139,10.10.2.140,10.10.2.141,10.10.2.142,10.10.2.143,10.10.2.144,10.10.2.145,10.10.2.146,10.10.2.147,10.10.2.148,10.10.2.149,10.10.2.150,10.10.2.151,10.10.2.152,10.10.2.153,10.10.2.154,10.10.2.155,10.10.2.156,10.10.2.157,10.10.2.158,10.10.2.159,10.10.2.160,10.10.2.161,10.10.2.162,10.10.2.163,10.10.2.164,10.10.2.165,10.10.2.166,10.10.2.167,10.10.2.168,10.10.2.169,10.10.2.170,10.10.2.171,10.10.2.172,10.10.2.173,10.10.2.174,10.10.2.175,10.10.2.176,10.10.2.177,10.10.2.178,10.10.2.179,10.10.2.180,10.10.2.181,10.10.2.182,10.10.2.183,10.10.2.184,10.10.2.185,10.10.2.186,10.10.2.187,10.10.2.188,10.10.2.189,10.10.2.190,10.10.2.191,10.10.2.192,10.10.2.193,10.10.2.194,10.10.2.195,10.10.2.196,10.10.2.197,10.10.2.198,10.10.2.199,10.10.2.200,10.10.2.201,10.10.2.202,10.10.2.203,10.10.2.204,10.10.2.205,10.10.2.206,10.10.2.207,10.10.2.208,10.10.2.209,10.10.2.210,10.10.2.211,10.10.2.212,10.10.2.213,10.10.2.214,10.10.2.215,10.10.2.216,10.10.2.217,10.10.2.218,10.10.2.219,10.10.2.220,10.10.2.221,10.10.2.222,10.10.2.223,10.10.2.224,10.10.2.225,10.10.2.226,10.10.2.227,10.10.2.228,10.10.2.229,10.10.2.230,10.10.2.231,10.10.2.232,10.10.2.233,10.10.2.234,10.10.2.235,10.10.2.236,10.10.2.237,10.10.2.238,10.10.2.239,10.10.2.240,10.10.2.241,10.10.2.242,10.10.2.243,10.10.2.244,10.10.2.245,10.10.2.246,10.10.2.247,10.10.2.248,10.10.2.249,10.10.2.250,10.10.2.251,10.10.2.252,10.10.2.253,10.10.2.254" openstack
