Configuring the Bare Metal Instance Management Drivers

The BMS uses the bare metal instance management drivers to manage bare metal instances. The bare metal instance management driver consists of a series of hardware interfaces to implement related operations. The drivers are classified into general-purpose drivers such as ipmi and redfish, and drivers of specific vendors such as ibmc, ilo, and irmc. This section uses the ipmi driver as an example to describe how to add a bare metal instance management driver to the BMS.

Perform the following operations on the BMS management node baremetal.

Enable the bare metal instance management driver.
Modify the /etc/ironic/ironic.conf file as follows:
1 2
[DEFAULT] enabled_hardware_types = ipmi

Enable the hardware interfaces.

Modify the /etc/ironic/ironic.conf file as follows:

[DEFAULT]
enabled_boot_interfaces = pxe
enabled_console_interfaces =  ipmitool-socat,no-console
enabled_deploy_interfaces = iscsi,direct
enabled_inspect_interfaces = no-inspect,inspector
enabled_management_interfaces = ipmitool
enabled_network_interfaces = flat,neutron
enabled_power_interfaces = ipmitool
enabled_raid_interfaces = agent,no-raid
enabled_storage_interfaces = cinder,noop
enabled_vendor_interfaces = ipmitool,no-vendor

Set the default values of the hardware interfaces.

Modify the /etc/ironic/ironic.conf file as follows:

[DEFAULT]
default_deploy_interface = iscsi
default_network_interface = flat
default_inspect_interface = inspector
default_raid_interface = no-raid

Configure the IPMI support.
1. Install ipmitool.
  1
  sudo yum install ipmitool
  Alternatively, you can use the source code from https://github.com/ipmitool/ipmitool to install it.
2. After the installation is complete, run the ipmitool command to verify the installation.
  1
  ipmitool -I lanplus -H ip-address -U username -P password chassis power status
  Set ip-address, username, and password to the IP address, username, and password of the BMC on the server to be verified.
Configure the ISCSI support.
Install the qemu-img and iscsiadm tools on the ironic-conductor node.
1
yum install iscsi-initiator-utils qemu-img

Configure the direct deployment support.

The direct deployment can be implemented through the object storage service or HTTP service. If the object storage service is used, the Glance service must be interconnected with Swift or Ceph, and tempUrl must be configured for the object storage service. This section uses the HTTP service to implement the direct deployment.

Install the Apache service.
```
sudo yum install httpd
```

Enable the Apache httpd service.

systemctl enable httpd.service
systemctl restart httpd.service

Create an HTTP root directory.

sudo mkdir -p /httpboot
sudo chown -R ironic /httpboot

Create an ironic-http-wsgi.conf file in the /etc/httpd/conf.d directory and add the following content to the file:

Listen 3928
 
<VirtualHost *:3928>
    DocumentRoot "/httpboot"
    <Directory "/httpboot">
        Options Indexes FollowSymLinks
        AllowOverride None
        Order allow,deny
        Allow from all
        Require all granted
    </Directory>
</VirtualHost>

Reload the configuration file.
1
sudo systemctl reload httpd
Modify the /etc/ironic/ironic.conf file as follows:
1 2 3 4 5 6
[deploy] http_root=/httpboot http_url=${my_ip}:3928 [agent] image_download_source = http
In addition, ensure that http_url and http_root are correctly configured.

Restart the service.

sudo systemctl restart openstack-ironic-conductor
