@File Create by Benjamin Lu, the cloud architect at Cephswift, if anyone has questions regarding the doc, please send mail to benlu369@yahoo.com.
\n@The Red Hat build doc is based on “Red Hat Enterprise Linux OpenStack Platform 7,8,9 Director Installation and Usage”.<\/p>\n
Notes on Red Hat OpenStack Platform 7 build-up:<\/p>\n
1. Build-up Red Hat OpenStack Undercloud :
\n1.1 Setup Undercloud ( on a pre-installed RHEL7 server)
\n[root@director ~]# useradd stack
\n[root@director ~]# passwd stack # specify a password
\n[root@director ~]# echo “stack ALL=(root) NOPASSWD:ALL” | tee -a \/etc\/sudoers.d\/stack
\n[root@director ~]# chmod 0440 \/etc\/sudoers.d\/stack
\n[root@director ~]# su – stack
\n$ mkdir ~\/images
\n$ mkdir ~\/templates<\/p>\n
$ hostname # Checks the base hostname
\n$ hostname -f # Checks the long hostname (FQDN) ### use this command to setup host name for undercloud installator
\n## example to setup host name for undercloud installator:
\n$ sudo hostnamectl set-hostname manager.example.com #### we may use < OSP7_director.cephswift.com> here as:
\n$ sudo hostnamectl set-hostname OSP7_director.cephswif.com
\n$ sudo hostnamectl set-hostname –transient manager.example.com #### we may use < OSP7_director.cephswift.com> here as:
\n$ sudo hostnamectl set-hostname –transient OSP7_director1.cephswift.com<\/p>\n
1.2 Registering the setup with Red Hat Subscription Manager, to have a full repo pkg access to download, install, update your OS, openstack software for your setup:<\/p>\n
$ sudo subscription-manager register userid=, password= $ sudo subscription-mamnger list –availble –all
\n$ sudo subscription-manager repos –disable=*
\n$ sudo subscription-manager repos \\
\n–enable=rhel-7-server-rpms \\
\n–enable=rhel-7-server-optional-rpms \\
\n–enable=rhel-7-server-extras- rpms \\
\n–enable=rhel-7-server-openstack-7.0-rpms \\
\n–enable=rhel-7- server-openstack-7.0-director-rpms
\n$ sudo yum install yum-plugin-priorities<\/p>\n
$ sudo yum install yum-utils
\n$ sudo yum-config-manager –enable reponame — setopt=”reponame.priority=1″<\/p>\n
$ sudo yum update -y
\n$ reboot<\/p>\n
1.3 Installing the Direct or Packages
\n[stack@director ~]$ sudo yum install -y python-rdomanager-oscplugin<\/p>\n
1.4. Configuring & Install Director ( In undercloud)
\n$ cp \/usr\/share\/instack-undercloud\/undercloud.conf.sample ~\/undercloud.conf
\n$ vi ~\/undercloud.conf ### to setup all IPs you are planning for your openstack environment, refer Red Hat doc for details.
\n$ openstack undercloud install ### this will install everything for undercloud for your configuration along with repos you registerted, it talk sometime.
\n$ source ~\/stackrc ### go your undercloud Env<\/p>\n
2. Build-up Red Hat OpenStack Overcloud :<\/p>\n
2.1 Get images for Overcloud nodes:
\n$ cd ~\/images
\nwget URL:
\nObtain these images from the Red Hat Enterprise Linux OpenStack Platform downloads page on the Red Hat Customer Portal at https:\/\/access.redhat.com\/downloads\/content\/191\/ver=7\/rhel—
\n7\/7\/x86_64\/product-downloads. This location on the Customer Portal contains the images in TAR. Customer login is needed to on Redhat Site.
\narchives.
\n$ for tarfile in *.tar; do tar -xf $tarfile; done;<\/p>\n
2.2 Upload image from download into director in underclod:
\n$ openstack overcloud image upload –image-path \/home\/stack\/images\/<\/p>\n
2.3 Verify image list and PXE, httpboot<\/p>\n
$ openstack image list
\n$ ls \/httpboot -l<\/p>\n
2.4 setup nameserver and Neutron Subnet
\n$ neutron subnet-list
\n$ neutron subnet-update [subnet-uuid] –dns-nameserver [nameserver-ip]
\n$ neutron subnet-show [subnet-uuid] ### verify<\/p>\n
2.5 Planning Overcloud ### check details on Redhat Docs according your Env<\/p>\n
2.6 Check default Direct Plants for Heat templates collections:
\n$ openstack management plan list<\/p>\n
$ openstack management plan show [UUID]
\nThis collection is stored in \/usr\/share\/openstack-tripleo-heat-templates.<\/p>\n
[stack@osp7-director ~]$ ls -l \/usr\/share\/openstack-tripleo-heat-templates

3 Installing the Overcloud:
\n3.1 Registering Nodes for the Basic Overcloud<\/p>\n
Create a node definition template. This file (instackenv.json )
\nvi \/home\/stack\/instackenv.json ### see details on redhat docs<\/p>\n
$ openstack baremetal import –json ~\/instackenv.json ### import it into the director.
\n$ openstack baremetal configure boot ### Assign the kernel and ramdisk images to all nodes:
\n$ opestack baremetal list ### use Cli to verify nodes has been registered for Openstack installation<\/p>\n
3.2 Inspecting the Hardware of Nodes
\n$ openstack baremetal introspection bulk start
\n$ sudo journalctl -l -u openstack-ironic-discoverd -u openstack-ironic- discoverd-dnsmasq -u openstack-ironic-conductor -f
\n$ ironic node-set-maintenance [NODE UUID] true
\n$ openstack baremetal introspection start [NODE UUID]
\n$ ironic node-set-maintenance [NODE UUID] false<\/p>\n
3.3 Manually Tagging the Nodes<\/p>\n
$ ironic node-update 58c3d07e-24f2-48a7-bbb6-6843f0e8ee13 add properties\/capabilities=’profile:compute,boot_option:local’
\n$ ironic node-update 1a4e30da-b6dc-499d-ba87-0bd8a3819bc0 add properties\/capabilities=’profile:control,boot_option:local’
\nThe addition of the profile:compute and profile:control options tag the two nodes into each respective profiles.<\/p>\n
3.4 Creating Flavors for the Basic Scenario
\n$ openstack flavor create –id auto –ram 6144 –disk 40 –vcpus 4 control
\n$ openstack flavor create –id auto –ram 6144 –disk 40 –vcpus 4 compute<\/p>\n
$ openstack flavor set –property “cpu_arch”=”x86_64” –property “capabilities:boot_option”=”local” –property “capabilities:profile”=”compute” compute
\n$ openstack flavor set –property “cpu_arch”=”x86_64” –property “capabilities:boot_option”=”local” –property “capabilities:profile”=”control” control
\n$ openstack flavor create –id auto –ram 4096 –disk 40 –vcpus 1 baremetal<\/p>\n
3.5 Configuring NFS Storage
\n$ cp \/usr\/share\/openstack-tripleo-heat-templates\/environments\/storage- environment.yaml<\/p>\n
3.6 Isolating the External Network ### see Red Hat docs for details<\/p>\n
3.7 Creating Custom Interface Templates
\n$ cp -r \/usr\/share\/openstack-tripleo-heat- templates\/network\/config\/single-nic-vlans ~\/templates\/nic-configs<\/p>\n
3.8 Creating a Basic Overcloud Network Environment Template
\nvi \/home\/stack\/templ ates\/netwo rk-envi ro nment. yaml<\/p>\n
3.9 Creating the Basic Overcloud
\n$ openstack overcloud deploy –templates -e \/usr\/share\/openstack-tripleo- heat-templates\/environments\/network-isolation.yaml -e \/home\/stack\/templates\/network-environment.yaml -e \\
\n\/home\/stack\/templates\/storage-environment.yaml –control-flavor control – -compute-flavor compute –ntp-server pool.ntp.org –neutron-network-type vxlan –neutron-tunnel-types vxlan<\/p>\n
Example:
\n$ openstack overcloud deploy –templates -e \/usr\/share\/openstack-tripleo-heat-templates\/environments\/network-isolation.yaml -e \/home\/stack\/templates\/network-environment.yaml -e \/home\/stack\/templates\/haproxy\/post_haproxy.yaml –control-scale 3 –compute-scale 11 –control-flavor control –compute-flavor compute –ntp-<\/p>\n
$ openstack help overcloud deploy ### for full list of options about deploy<\/p>\n
$ source ~\/stackrc ### Initializes the stack ussrs to use the Cli commands<\/p>\n
$ heat stack-list –show-nested<\/p>\n
3.10 Accessing the Basic Overcloud :<\/p>\n
The director generates a file to configure and authenticate interactions with your Overcloud from the Undercloud.
\nThe director saves this file, overcloudrc, in your stack user’s home directory.<\/p>\n
Run the following command to use this file:
\n$ source ~\/overcloudrc<\/p>\n
This loads the necessary environment variables to interact with your Overcloud from the director host’s CLI.
\nTo return to interacting with the director’s host, run the following command:
\n$ source ~\/stackrc<\/p>\n","protected":false},"excerpt":{"rendered":"
