Upgrading the postanalytics module

These instructions describe the steps to upgrade the postanalytics module 3.4 or 3.2 installed on a separate server. Postanalytics module must be upgraded before Upgrading Wallarm NGINX modules.

To upgrade the module 2.18 or lower, please use the different instructions.

Requirements

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

  • Access to https://api.wallarm.com if working with EU Wallarm Cloud or to https://us1.api.wallarm.com if working with US 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 api.wallarm.com:443 (EU Cloud) and us1.api.wallarm.com:443 (US Cloud) API endpoints instead of api.wallarm.com:444 and us1.api.wallarm.com:444.

If 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 to version 4.0 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/6/4.0/x86_64/wallarm-node-repo-4-0.el6.noarch.rpm
sudo yum remove wallarm-node-repo
sudo yum clean all
sudo rpm -i https://repo.wallarm.com/centos/wallarm-node/7/4.0/x86_64/wallarm-node-repo-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/8/4.0/x86_64/wallarm-node-repo-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:

    deb http://repo.wallarm.com/debian/wallarm-node stretch/4.0/
    
    deb http://repo.wallarm.com/debian/wallarm-node stretch/4.0/
    deb http://repo.wallarm.com/debian/wallarm-node stretch-backports/4.0/
    
    deb http://repo.wallarm.com/debian/wallarm-node buster/4.0/
    
    deb http://repo.wallarm.com/debian/wallarm-node bullseye/4.0/
    
    deb http://repo.wallarm.com/ubuntu/wallarm-node bionic/4.0/
    
    deb http://repo.wallarm.com/ubuntu/wallarm-node focal/4.0/
    

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/4.0/ 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/4.0/ 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
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/4.0/ 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/4.0/ 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
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 4.0. 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 EU Cloud or US Cloud.

    User list in Wallarm console

  2. Open Wallarm Console → Nodes in the EU Cloud or US 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> --force --no-sync --no-sync-acl
    
    sudo /usr/share/wallarm-common/register-node -t <NODE_TOKEN> -H us1.api.wallarm.com --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
