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

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

Platform specific notes

Depending on what operating system you are using, you may need to enable or disable specific modules to install Percona Distribution for PostgreSQL packages and to resolve dependencies conflicts for its specific components.

For Percona Distribution for PostgreSQL packages

=== "CentOS 7"

Install the `epel-release` package:

```{.bash data-prompt="$"}
$ sudo yum -y install epel-release
$ sudo yum repolist
```

=== "RHEL8/Oracle Linux 8/Rocky Linux 8"

Disable the ``postgresql`` module:    

```{.bash data-prompt="$"}
$ sudo dnf module disable postgresql 
```

For percona-postgresql{{pgversion}}-devel package

You may need to install the percona-postgresql{{pgversion}}-devel package when working with some extensions or creating programs that interface with PostgreSQL database. This package requires dependencies that are not part of the Distribution, but can be installed from the specific repositories:

=== "RHEL8"

```{.bash data-prompt="$"}
$ sudo yum --enablerepo=codeready-builder-for-rhel-8-rhui-rpms 
$ sudo dnf install perl-IPC-Run -y
```

=== "Rocky Linux 8"

```{.bash data-prompt="$"}
$ sudo dnf install dnf-plugins-core
$ sudo dnf config-manager --set-enabled powertools
```

=== "Oracle Linux 8"

```{.bash data-prompt="$"}
$ sudo dnf config-manager --set-enabled ol8_codeready_builder 
$ sudo dnf install perl-IPC-Run -y
```

=== "Rocky Linux 9"

```{.bash data-prompt="$"}
$ sudo dnf install dnf-plugins-core
$ sudo dnf config-manager --set-enabled crb
$ sudo dnf install perl-IPC-Run -y
```

=== "Oracle Linux 9"

```{.bash data-prompt="$"}
$ sudo dnf config-manager --set-enabled ol9_codeready_builder 
$ sudo dnf install perl-IPC-Run -y
```

For percona-patroni package

To install Patroni on Red Hat Enterprise Linux 9 and compatible derivatives, enable the epel repository

$ sudo yum install epel-release

For pgpool2 extension

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 are commands for Red Hat Enterprise Linux 9 and derivatives. For Red Hat Enterprise Linux 8, replace the operating system version in the commands accordingly.

=== "RHEL 9"

```{.bash data-prompt="$"}
$ sudo dnf config-manager --set-enabled codeready-builder-for-rhel-9-x86_64-rpms
```

=== "Rocky Linux 9"

```{.bash data-prompt="$"}
$ sudo dnf config-manager --set-enabled crb
```

=== "Oracle Linux 9"

```{.bash data-prompt="$"}
$ sudo dnf config-manager --set-enabled ol9_codeready_builder
```

For PostGIS

For Red Hat Enterprise Linux 8 and derivatives, replace the operating system version in the following commands accordingly.

=== "RHEL 9"

Run the following commands:
{.power-number}

1. Install `epel` repository

    ```{.bash data-prompt="$"}
    $ sudo yum install epel-release
    ```

2. Enable the codeready builder repository to resolve dependencies conflict. 

    ```{.bash data-prompt="$"}
    $ sudo dnf config-manager --set-enabled codeready-builder-for-rhel-9-x86_64-rpms
    ```

=== "Rocky Linux 9"

Run the following commands:
{.power-number}

1. Install `epel` repository

    ```{.bash data-prompt="$"}
    $ sudo yum install epel-release
    ```

2. Enable the codeready builder repository to resolve dependencies conflict.

    ```{.bash data-prompt="$"}
    $ sudo dnf install dnf-plugins-core
    $ sudo dnf config-manager --set-enabled crb
    ```

=== "Oracle Linux 9"

Run the following commands:
{.power-number}

1. Install `epel` repository

    ```{.bash data-prompt="$"}
    $ sudo yum install epel-release
    ```

2. Enable the codeready builder repository to resolve dependencies conflict.

    ```{.bash data-prompt="$"}
    $ sudo dnf config-manager --set-enabled ol9_codeready_builder
    ```

=== "RHEL UBI 9"

Run the following commands:
{.power-number}

1. Configure the Oracle-Linux repository. Create the `/etc/yum.repos.d/oracle-linux-ol9.repo` file to install the required dependencies: 

    ```init title="/etc/yum.repos.d/oracle-linux-ol9.repo"
    [ol9_baseos_latest]
    name=Oracle Linux 9 BaseOS Latest ($basearch)
    baseurl=https://yum.oracle.com/repo/OracleLinux/OL9/baseos/latest/$basearch/
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
    gpgcheck=1
    enabled=1     

    [ol9_appstream]
    name=Oracle Linux 9 Application Stream ($basearch)
    baseurl=https://yum.oracle.com/repo/OracleLinux/OL9/appstream/$basearch/
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
    gpgcheck=1
    enabled=1     

    [ol9_codeready_builder]
    name=Oracle Linux 9 CodeReady Builder ($basearch) - Unsupported
    baseurl=https://yum.oracle.com/repo/OracleLinux/OL9/codeready/builder/$basearch/
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
    gpgcheck=1
    enabled=1
    ```

2. Download the right GPG key for the Oracle Yum Repository:    

    ```{.bash data-prompt="$"}
    $ wget https://yum.oracle.com/RPM-GPG-KEY-oracle-ol9 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
    ```    

3. Install `epel` repository    

    ```{.bash data-prompt="$"}
    $ sudo yum install epel-release
    ```    

4. Disable the upstream `postgresql` package:    

    ```{.bash data-prompt="$"}
    $ sudo dnf module disable postgresql
    ```

Procedure

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

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

    $ sudo percona-release setup ppg{{pgversion}}

Install packages

=== "Install using meta-package"

 The [meta package](repo-overview.md#percona-ppg-server){:target=”_blank”} enables you to install several components of the distribution in one go.
 
 ```{.bash data-prompt="$"}
 $ sudo yum install percona-ppg-server{{pgversion}}
 ```

    $ sudo yum install percona-pgvector_{{pgversion}} percona-pgvector_{{pgversion}}-debuginfo percona-pgvector_{{pgversion}}-debugsource percona-pgvector_{{pgversion}}-llvmjit
    ```

    Some extensions require additional setup in order to use them with Percona Distribution for PostgreSQL. For more information, refer to [Enabling extensions](enable-extensions.md).

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-{{pgversion}}/bin/postgresql-{{pgversion}}-setup initdb

Start the PostgreSQL service:

$ sudo systemctl start postgresql-{{pgversion}}

Check the Percona Distribution for PostgreSQL version:

$ psql --version

??? example "Sample output"

```{.text .no-copy}
psql (PostgreSQL) {{pspgversion}} (Percona Server for PostgreSQL) {{pspgversion}}
```

Congratulations! Your Percona Distribution for PostgreSQL is up and running.
