Configuring the Overcloud

Configuring the Overcloud

After the Overcloud is installed, log in to the Controller node and check whether the /etc/nova/nova.conf file contains the following filtering rules. If not, add the filtering rules. If you do not add them, new VMs cannot be added to the specified HA. (If there are fewer than two Compute nodes, skip this step.)

Log in to each of the three Controller nodes, run the vi /etc/nova/nova.conf command, and modify the nova.conf file.


Restart all Nova services of the three Controller nodes as follows:

  1. Run the systemctl | grep nova command to view all Nova services.

  2. Run the systemctl restart service command to restart all Nova services.

Note: Switch to the stack user on the director node, run the source stackrc command, and then run the ssh heat-admin@IP address automatically allocated by the PXE on each node command. First execution of the ssh command takes a long time. To solve this problem, open the /etc/ssh/sshd_conf file, change #UseDNS yes to UseDNS no, save the file, and restart the SSHD service.

  • On the director node:

    Run the vim /etc/ssh/sshd_conf command to open the file.

    Run the systemctl restart sshd command to restart the SSHD service.

  • On other nodes:

    Log in to the director node in SSH mode and run the sudo -i command to switch to the root user.
