2.2. Installing repmgr from packages

2.2.1. RedHat/CentOS/Fedora
2.2.2. Debian/Ubuntu

We recommend installing repmgr using the available packages for your system.

2.2.1. RedHat/CentOS/Fedora

repmgr RPM packages for RedHat/CentOS variants and Fedora are available from the 2ndQuadrant public repository; see following section for details.

RPM packages for repmgr are also available via Yum through the PostgreSQL Global Development Group RPM repository (http://yum.postgresql.org/). Follow the instructions for your distribution (RedHat, CentOS, Fedora, etc.) and architecture as detailed there. Note that it can take some days for new repmgr packages to become available via the this repository.

Note

repmgr RPM packages are designed to be compatible with the community-provided PostgreSQL packages and 2ndQuadrant's 2ndQPostgres. They may not work with vendor-specific packages such as those provided by RedHat for RHEL customers, as the PostgreSQL filesystem layout may be different to the community RPMs. Please contact your support vendor for assistance.

See also FAQ entry Compatability with third party vendor packages.

For more information on the package contents, including details of installation paths and relevant service commands, see the appendix section CentOS packages.

2.2.1.1. 2ndQuadrant public RPM yum repository

2ndQuadrant provides a dedicated yum public repository for 2ndQuadrant software, including repmgr. We recommend using this for all future repmgr releases.

General instructions for using this repository can be found on its homepage. Specific instructions for installing repmgr follow below.

Installation

  • Locate the repository RPM for your PostgreSQL version from the list at: https://dl.2ndquadrant.com/

  • Install the repository definition for your distribution and PostgreSQL version (this enables the 2ndQuadrant repository as a source of repmgr packages).

    For example, for PostgreSQL 11 on CentOS, execute:

    curl https://dl.2ndquadrant.com/default/release/get/11/rpm | sudo bash

    For PostgreSQL 9.6 on CentOS, execute:

    curl https://dl.2ndquadrant.com/default/release/get/9.6/rpm | sudo bash

    Verify that the repository is installed with:

    sudo yum repolist

    The output should contain two entries like this:

    2ndquadrant-dl-default-release-pg11/7/x86_64         2ndQuadrant packages (PG11) for 7 - x86_64               18
    2ndquadrant-dl-default-release-pg11-debug/7/x86_64   2ndQuadrant packages (PG11) for 7 - x86_64 - Debug        8

  • Install the repmgr version appropriate for your PostgreSQL version (e.g. repmgr10):

    sudo yum install repmgr11

    Note

    For packages for PostgreSQL 9.6 and earlier, the package name does not contain a period between major and minor version numbers, e.g. repmgr96.

    Tip

    To determine the names of available packages, execute:

    yum search repmgr

Compatibility with PGDG Repositories

The 2ndQuadrant repmgr yum repository packages use the same definitions and file system layout as the main PGDG repository.

Normally yum will prioritize the repository with the most recent repmgr version. Once the PGDG repository has been updated, it doesn't matter which repository the packages are installed from.

To ensure the 2ndQuadrant repository is always prioritised, install yum-plugin-priorities and set the repository priorities accordingly.

Installing a specific package version

To install a specific package version, execute yum --showduplicates list for the package in question:

[root@localhost ~]# yum --showduplicates list repmgr11

repmgr11.x86_64                        4.3-1.el7                             2ndquadrant-dl-default-release-pg11
repmgr11.x86_64                        4.4-1.el7                             2ndquadrant-dl-default-release-pg11

then append the appropriate version number to the package name with a hyphen, e.g.:

[root@localhost ~]# yum install repmgr11-4.3-1.el7
