Creating a cluster of 1C:Enterprise Linux servers with Managed Service for PostgreSQL

Yandex.Cloud lets you create PostgreSQL clusters optimized for 1C:Enterprise. To configure the use of 1C:Enterprise, you need to create a working server, a license server, and a Managed Service for PostgreSQL cluster. For 1C servers to run correctly, you should disable security services on them. Therefore the cluster will be accessed via an encrypted OpenVPN server connection, while the 1C servers will have no access to the internet. The 1C servers will be running CentOS 8. The 1C cluster will be configured using the Windows administration console.

Note

To use 1C:Enterprise, you need a license. For more information about licenses and their installation, see the 1C:Enterprise website.

To configure 1C:Enterprise servers:

  1. Before you start.
  2. Prepare the infrastructure.
  3. Create a VM for the 1C:Enterprise server.
  4. Create a VM for the license server.
  5. Create a Managed Service for PostgreSQL cluster.
  6. Set up a Samba server.
  7. Install the 1C:Enterprise server.
  8. Set up a Samba server for the license server.
  9. Install the 1C:Enterprise server for the license server.
  10. Set up a server cluster.
  11. Set up an infobase.
  12. Connect to the infobase.

If you no longer need the created resources, delete them.

Before you start

Before deploying the server, you need to sign up for Yandex.Cloud and create a billing account:

  1. Go to the management console. Then log in to Yandex.Cloud or sign up if don't already have an account.
  2. On the billing page, make sure you linked a billing account, and it has the ACTIVE or TRIAL_ACTIVE status. If you don't have a billing account, create one.

If you have an active billing account, you can create or select a folder to run your VM in from the Yandex.Cloud page.

Learn more about clouds and folders.

The infrastructure support cost for 1C-Enterprise in Yandex.Cloud includes:

Prepare the infrastructure

  1. Make sure that you install the 1C:Enterprise client to check the performance of the infobase and the 1C administration console to manage the server cluster on your computer.
  2. Make sure you have a VM running in your cloud with OpenVPN configured for a secure connection to the 1C servers.

Note

You can download the necessary distributions from the 1C:Enterprise website.

Create a VM for the 1C:Enterprise server

To create a VM:

  1. On the folder page in the management console, click Create resource and select Virtual machine.

  2. In the Name field, enter the VM name: server-1c.

  3. Select the availability zone to host the VM in.

  4. Under Images from Cloud Marketplace, click Select. Select a public CentOS 8 image.

  5. Under Computing resources:

    • Choose a platform.
    • Specify the number of vCPUs and amount of RAM:
      • vCPU: 4.
      • Guaranteed vCPU share: 100%.
      • RAM: 4 GB.

  6. In the Network settings section, select the network and subnet to connect the VM to. If you don't have a network or subnet, create them right on the VM creation page.

  7. In the Public address field, leave the value No address. The VM will be accessed via the OpenVPN server.

  8. Specify data required for accessing the VM:

    • Enter the username in the Login field.

    • In the SSH key field, paste the contents of the public key file.

      You need to create a key pair for the SSH connection yourself. Learn how to connect to VMs via SSH.

  9. Click Create VM.

Creating the VM may take several minutes.

Create a VM for the license server

Install the 1C:Enterprise license on a separate server. This way changes to the configuration of other servers won't affect the installed license.

To create a VM:

  1. On the folder page in the management console, click Create resource and select Virtual machine.

  2. In the Name field, enter the VM name: licensing-server-1c.

  3. Select the availability zone to host the VM in.

  4. Under Images from Cloud Marketplace, click Select. Select a public CentOS 8 image.

  5. Under Computing resources:

    • Choose a platform.
    • Specify the number of vCPUs and amount of RAM:
      • vCPU: 4.
      • Guaranteed vCPU share: 100%.
      • RAM: 4 GB.

  6. In the Network settings section, select the network and subnet to connect the VM to. The VM should be created in the same subnet as the OpenVPN server.

  7. In the Public address field, leave the value No address. The VM will be accessed via the OpenVPN server.

  8. Specify data required for accessing the VM:

    • Enter the username in the Login field.
    • In the SSH key field, paste the contents of the public key file.

  9. Click Create VM.

Creating the VM may take several minutes.

Create a cluster Managed Service for PostgreSQL

Yandex.Cloud lets you create Managed Service for PostgreSQL clusters optimized for 1C:Enterprise. Cluster settings may vary depending on your project requirements.

To create a Managed Service for PostgreSQL cluster optimized for 1C:
