We recommend installing repmgr using the available packages for your system.
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 packages are designed to be compatible with the community-provided PostgreSQL packages. They may not work with vendor-specific packages such as those provided by RedHat for RHEL customers, as the filesystem layout may be different to the community RPMs. Please contact your support vendor for assistance.
For more information on the package contents, including details of installation paths and relevant service commands, see the appendix section CentOS packages.
Beginning with repmgr 4.0.5, 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 10 on CentOS, execute:
curl https://dl.2ndquadrant.com/default/release/get/10/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-pg10/7/x86_64 2ndQuadrant packages (PG10) for 7 - x86_64 4 2ndquadrant-dl-default-release-pg10-debug/7/x86_64 2ndQuadrant packages (PG10) for 7 - x86_64 - Debug 3
Install the repmgr version appropriate for your PostgreSQL version (e.g. repmgr10):
$ yum install repmgr10
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 repmgr10
