Webplugin virtualization

As root, on the command line of your Esia

copy

apt update
apt install esia-webp-virtualization

Always configure a Virtual Cluster node. Even if the hypervisor is alone and not connected to a Vcenter.

You need to configure :

• The name of the desired node
• The 'Virtual cluster' node type
• The desired node group
• The IP address (for VMware, preferably vcenter, ESX if you have no choice).
• A desired description.
• SNMP parameters (optional)

Currently, the virtualisation webplugin is only accessible live and cannot be used through Unity.

You now need to choose the driver you want, depending on the type of hypervisor.

The node's URL is automatically configured according to the IP encoded above. But you can modify the url.

Configure the login and password and click save

An error message is displayed indicating that it is impossible to recover the data. But the configuration is still saved. This allows the device to be configured later.

For VMWare only, as it is not possible to retrieve the cluster name (in Vcenter), or even to know whether it is a Vcenter or ESX hypervisor, a textbox is displayed allowing you to encode it.

In this case, the configuration is saved but a message warns that it is advisable to use the vcenter

In this case there is nothing to report.

The cluster name is automatically configured without any intervention being required.

You then need to select the desired cluster from the list.

On the previously encoded Vcenter main page.

If you receive the error message “Allowed memory size of XXX bytes exhausted …”. This means you need to allocate more memory to your Esia web server. To do this, you need to modify the php.ini file via SSH (root) on the Esia server. Note that the file path contains the latest version of PHP installed on your server (here, 8.2).

copy

nano /etc/php/8.2/apache2/php.ini

Press ctrl+w to search for “memory_limit” and find the line :

php_value memory_limit 128M

Increase this number (without exaggeration). Here we will replace the line with :

copy

php_value memory_limit 256M

Next, save the file and then restart the Apache server.

copy

service apache2 restart
