Upgrading the EOL postanalytics module

These instructions describe the steps to upgrade the end‑of‑life postanalytics module (version 3.6 and lower) installed on a separate server. Postanalytics module must be upgraded before Upgrading Wallarm NGINX modules.

Wallarm nodes 3.6 and lower are not supported

You are recommended to upgrade the Wallarm nodes 3.6 and lower since these versions are not supported, they are end-of-life.

Node configuration and traffic filtration have been significantly simplified in the Wallarm node of the latest versions. Before upgrading the modules, please carefully review the list of changes and general recommendations. Please note that some settings of the latest node are incompatible with the nodes 3.6 and lower.

Requirements

  • Access to the account with the Administrator role in Wallarm Console in the US Cloud or EU Cloud

  • Access to https://us1.api.wallarm.com if working with US Wallarm Cloud or to https://api.wallarm.com if working with EU Wallarm Cloud. Please ensure the access is not blocked by a firewall

Step 1: Update API port

Starting with version 4.0, the filtering node uploads data to the Cloud using the us1.api.wallarm.com:443 (US Cloud) and api.wallarm.com:443 (EU Cloud) API endpoints instead of us1.api.wallarm.com:444 and api.wallarm.com:444.

If you upgrade the node from the version 3.x or lower and your server with the deployed node has a limited access to the external resources and the access is granted to each resource separately, then after upgrade the synchronization between the filtering node and the Cloud will stop.

To restore the synchronization, in your configuration, change port 444 to 443 for API endpoint for each resource.

Step 2: Add new Wallarm repository

Delete the previous Wallarm repository address and add a repository with a new Wallarm node version packages. Please use the commands for the appropriate platform.

CentOS and Amazon Linux 2.0.2021x and lower

sudo yum remove wallarm-node-repo
sudo yum clean all
sudo rpm -i https://repo.wallarm.com/centos/wallarm-node/7/4.4/x86_64/wallarm-node-repo-4.4-0.el7.noarch.rpm

Support for CentOS 8.x has been deprecated

Support for CentOS 8.x has been deprecated. You can install the Wallarm node on the AlmaLinux, Rocky Linux or Oracle Linux 8.x operating system insted.

sudo yum remove wallarm-node-repo
sudo yum clean all
sudo rpm -i https://repo.wallarm.com/centos/wallarm-node/8/4.4/x86_64/wallarm-node-repo-4.4-0.el8.noarch.rpm

Debian and Ubuntu

  1. Open the file with the Wallarm repository address in the installed text editor. In this instruction, vim is used.

    sudo vim /etc/apt/sources.list.d/wallarm.list
    
  2. Comment out or delete the previous repository address.

  3. Add a new repository address:

    Unsupported by NGINX stable and NGINX Plus

    Official NGINX versions (stable and Plus) and, as a result, Wallarm node 4.4 and above cannot be installed on Debian 10.x (buster). Please use this OS only if NGINX is installed from Debian/CentOS repositories.

    deb http://repo.wallarm.com/debian/wallarm-node buster/4.4/
    
    deb http://repo.wallarm.com/debian/wallarm-node bullseye/4.4/
    
    deb http://repo.wallarm.com/ubuntu/wallarm-node bionic/4.4/
    
    deb http://repo.wallarm.com/ubuntu/wallarm-node focal/4.4/
    

Step 3: Upgrade the Tarantool packages

sudo apt update
sudo apt dist-upgrade

The error "signatures couldn't be verified"

If added GPG keys expired, the following error would be returned:

W: GPG error: http://repo.wallarm.com/ubuntu/wallarm-node focal/4.4/ Release:The following
signatures couldn't be verified because the public key is not available: NO_PUBKEY 1111FQQW999
E: The repository 'http://repo.wallarm.com/ubuntu/wallarm-node focal/4.4/ Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

To fix the problem, please import new GPG keys for the Wallarm packages and then upgrade the packages using the following commands:

curl -fsSL https://repo.wallarm.com/wallarm.gpg | sudo apt-key add -
sudo apt update
sudo apt dist-upgrade

Upgrading Wallarm dependencies

The sudo apt dist-upgrade command upgrades both the Wallarm packages and filtering node dependencies. It is the recommended upgrade option providing correct operation of the newer filtering node version.

sudo apt update
sudo apt dist-upgrade

The error "signatures couldn't be verified"

If added GPG keys expired, the following error would be returned:

W: GPG error: http://repo.wallarm.com/ubuntu/wallarm-node focal/4.4/ Release:The following
signatures couldn't be verified because the public key is not available: NO_PUBKEY 1111FQQW999
E: The repository 'http://repo.wallarm.com/ubuntu/wallarm-node focal/4.4/ Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

To fix the problem, please import new GPG keys for the Wallarm packages and then upgrade the packages using the following commands:

curl -fsSL https://repo.wallarm.com/wallarm.gpg | sudo apt-key add -
sudo apt update
sudo apt dist-upgrade

Upgrading Wallarm dependencies

The sudo apt dist-upgrade command upgrades both the Wallarm packages and filtering node dependencies. It is the recommended upgrade option providing correct operation of the newer filtering node version.

sudo yum update
sudo yum update

Step 4: Update the node type

The deployed postanalytics node 3.6 or lower has the deprecated regular type that is now replaced with the new Wallarm node type.

It is recommended to install the new node type instead of the deprecated one during migration to the version 4.4. The regular node type will be removed in future releases, please migrate before.

To replace the regular postanalytics node with the Wallarm node:

  1. Make sure that your Wallarm account has the Administrator role enabled in Wallarm Console.

    You can check mentioned settings by navigating to the user list in the US Cloud or EU Cloud.

    User list in Wallarm console

  2. Open Wallarm Console → Nodes in the US Cloud or EU Cloud and create the node of the Wallarm node type.

    Wallarm node creation

  3. Copy the generated token.

  4. Execute the register-node script to run the Wallarm node:

    sudo /usr/share/wallarm-common/register-node -t <NODE_TOKEN> -H us1.api.wallarm.com --force --no-sync --no-sync-acl
    
    sudo /usr/share/wallarm-common/register-node -t <NODE_TOKEN> --force --no-sync --no-sync-acl
    
    • <NODE_TOKEN> is the Wallarm node token.
    • The --force option forces rewriting of the Wallarm Cloud access credentials specified in the /etc/wallarm/node.yaml file.

Step 5: Restart the postanalytics module

sudo systemctl restart wallarm-tarantool
sudo service wallarm-tarantool restart
sudo systemctl restart wallarm-tarantool
sudo systemctl restart wallarm-tarantool
