Verifying Completed Configuration

After installation and configuration are complete, run the following verification commands to confirm that the settings are correct and the required services are working properly. These commands check service status, network settings, and the overall health of the system.

Checking Hostname​

hostname

Example output:

pvm-node1

Checking IP Addresses​

ip -4 a

Example output:

2: mgmt
inet 172.30.30.10/24

Make sure the Management interface has received the correct IP address.

Checking the Default Gateway​

ip r

Example output:

default via 192.168.1.1 dev mgmt

Checking Gateway Connectivity​

To confirm network connectivity, ping the gateway.

ping -c 4 192.168.1.1

If the connection is successful, output similar to the following is displayed:

4 packets transmitted, 4 received, 0% packet loss

Checking Network Interface Status​

Run the following command to view the status of all network interfaces.

ip link

Example output:

mgmt       UP LOWER_UP
vmtraffic  UP LOWER_UP
Tip

The UP status indicates that the network interface is enabled, and LOWER_UP indicates that the physical network cable link is active.

Make sure at least the Management interface and the interface used for virtual machine traffic are in the UP and LOWER_UP states.

Checking the Plaivid IP​

To view or change the Management IP configured in Plaivid Manager, open the following configuration file with vi:

vi /var/www/html/plaivid/assets/.env

In this file, check the value of the URL variable. The IP address used by Plaivid Manager is located after https:// in this value. Edit and save it if needed.

Info

You can use the same method to view or change the IP address for the inad and fylad services by editing these files:

vi /var/www/html/inad/assets/.env
vi /var/www/html/fylad/assets/.env

In these files, check the URL variable and update it if needed.

Tip

If you changed the IP address

After applying the change, press Esc and enter the following command to save the file and exit vi:

:wq

Then press Enter to save the changes and close the file.

Finally, restart Nginx to apply the new settings:

systemctl restart nginx
