Preparing the Platform V Pangolin DBMS cluster for working with Kaspersky Security Center Linux

If you want to use Platform V Pangolin as a failover DBMS cluster, you have to install Platform V Pangolin or use an existing cluster.

A minimum Platform V Pangolin DBMS cluster configuration must include at least three nodes:

• Master node
• Replica node
• Arbiter node (no data storage, ensures quorum)

To prepare the Platform V Pangolin DBMS cluster for working with Kaspersky Security Center Linux:

1. Modify the configuration file /etc/pangolin-manager/postgres.yml on all Platform V Pangolin DBMS cluster nodes as follows:
   • Add the following line to the postgresql section, if you will specify only the DNS name or IP address of the master node, or the replica node when connecting the cluster to Kaspersky Security Center Linux:

     log_hostname: '1'

   • Change the following parameter value in the postgresql section:

     search_path: ext,public

   For other configuration file parameters, you can use the recommended parameter values for PostgreSQL and Postgres Pro.

2. After editing the configuration file /etc/pangolin-manager/postgres.yml, restart the pangolin-manager service on all Platform V Pangolin DBMS cluster nodes (excluding the arbiter node) as follows:

   systemctl restart pangolin-manager.service

The Platform V Pangolin DBMS cluster is ready for working with Kaspersky Security Center Linux. To connect the cluster to Kaspersky Security Center Linux, enter the DNS names, or IP addresses and ports of all cluster nodes during the installation of Kaspersky Security Center Linux at the step of specifying the DBMS address. Alternatively, you can specify only the DNS name or IP address of the master node, or the replica node when specifying the DBMS address.
