Installing pgEdge Distributed Postgres (VM Edition)
There are several ways to install pgEdge Distributed Postgres (VM Edition) and deploy a replication cluster. You can:
- Use the VM Edition's command-line interface (CLI)
clustermodule to create a .json file that deploys a cluster on local or remote hosts. This method also simplifies installation and configurion of pgBackRest on the new cluster. - Log in to each CLI host and manually deploy a cluster.
Installing the CLI
A distributed Postgres cluster traditionally lives on two or more hosts; to prepare a CLI host, you should:
- Set SELinux to
permissiveordisabledmode (opens in a new tab), followed by a system reboot. - Configure passwordless sudo access for a non-root OS user.
- Configure passwordless ssh access for the same non-root OS user.
- Open any firewalls that could obstruct access between hosts.
Then, install the CLI on each host with the command:
python3 -c "$(curl -fsSL https://downloads.pgedge.com/platform/repos/download/install.py)"
Paste the command into your command line client and press Return.
Note that depending on your system configuration, you may need to preface commands with sudo; for example, sudo python3 -c "$(curl -fsSL https://downloads.pgedge.com/platform/repos/download/install.py)".
