Install Percona Distribution for PostgreSQL on Red Hat Enterprise Linux and derivatives¶

This document describes how to install Percona Server for PostgreSQL from Percona repositories on RPM-based distributions such as Red Hat Enterprise Linux and compatible derivatives..

Platform specific notes¶

If you intend to install Percona Distribution for PostgreSQL on Red Hat Enterprise Linux v8, disable the postgresql and llvm-toolsetmodules:

$ sudo dnf module disable postgresql llvm-toolset

On CentOS 7, you should install the epel-release package:

$ sudo yum -y install epel-release
$ sudo yum repolist

Procedure¶

Run all the commands in the following sections as root or using the sudo command:

Configure the repository¶

Install the percona-release repository management tool to subscribe to Percona repositories:
```
$ sudo yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
```
Enable the repository

Percona provides two repositories for Percona Distribution for PostgreSQL. We recommend enabling the Major release repository to timely receive the latest updates.

To enable a repository, we recommend using the setup command:

$ sudo percona-release setup ppg-13

Install packages¶

Install using meta-packageInstall packages individually

$ sudo yum install percona-ppg-server13

Install the PostgreSQL server package:

$ sudo yum install percona-postgresql13-server

Install the components:

Install pg_repack:
```
$ sudo yum install percona-pg_repack13
```
Install pgaudit:
```
$ sudo yum install percona-pgaudit
```
Install pgBackRest:
```
$ sudo yum install percona-pgbackrest
```
Install Patroni:
```

```
Install pg_stat_monitor:

Install pgBouncer:
```
$ sudo yum install percona-pgbouncer
```
Install pgAudit-set_user:

```
Install HAProxy
```
$ sudo yum install percona-haproxy
```
Install pg_gather
```
$ sudo yum install percona-pg_gather
```
Install pgpool2

To install pgpool2 on Red Hat Enterprise Linux and compatible derivatives, enable the codeready builder repository first to resolve dependencies conflict for pgpool2. The following examples show steps for Red Hat Enterprise Linux 9.
RHEL 9CentOS 9Oracle Linux 9
1. Enable the codeready builder repository
  
  $ sudo dnf config-manager --set-enabled codeready-builder-for-rhel-9-x86_64-rpms
2. Install the extension
  
  $ sudo yum install percona-pgpool-II-pg13
1. Enable the codeready builder repository
  
  $ sudo dnf config-manager --set-enabled crb
2. Install the extension
  
  $ sudo yum install percona-pgpool-II-pg13
1. Enable the codeready builder repository
  
  $ sudo dnf config-manager --set-enabled ol9_codeready_builder
2. Install the extension
  
  $ sudo yum install percona-pgpool-II-pg13
For Red Hat Enterprise Linux 8, replace the operating system version in the commands accordingly.

Some extensions require additional setup in order to use them with Percona Distribution for PostgreSQL. For more information, refer to Enabling extensions.

Start the service¶

After the installation, the default database storage is not automatically initialized. To complete the installation and start Percona Distribution for PostgreSQL, initialize the database using the following command:

/usr/pgsql-13/bin/postgresql-13-setup initdb

Start the PostgreSQL service:

$ sudo systemctl start postgresql-13

Connect to the PostgreSQL server¶

By default, postgres user and postgres database are created in PostgreSQL upon its installation and initialization. This allows you to connect to the database as the postgres user.

$ sudo su postgres

Open the PostgreSQL interactive terminal:

$ psql

Hint

You can connect to psql as the postgres user in one go:

$ sudo su - postgres -c psql

To exit the psql terminal, use the following command:

$ \q
