Installing BDR from packages

Installation from packages is a good choice if you want the stable release, as it's easier to install and to keep track of your installation.
If you want the very latest BDR or if packages are not yet available for your operating system you may instead want to install from source code.
Note: These instructions are part of the BDR source code so they will be outdated if you are looking at documentation for an old BDR version. Installation from packages will typically install the latest stable BDR version.

3.2.1. RHEL, Fedora and CentOS

Packages for BDR are available for Red Hat derived distros - Fedora, RHEL, and CentOS. Install the repository RPMs

To install BDR from RPMs you should first download and install the repository RPM for your distro. This RPM will configure the download location for the BDR packages and load the signing key into your RPM database so that the package digital signatures may be verified.
Note: The repository RPM is signed with 2ndQuadrant's master packaging/releases signing key. See Verifying digital signatures.
RHEL and CentOS users should download and install the appropriate repo rpm:
     # RHEL/CentOS users only:
     sudo yum install http://packages.2ndquadrant.com/postgresql-bdr94-2ndquadrant/yum-repo-rpms/postgresql-bdr94-2ndquadrant-redhat-latest.noarch.rpm
Fedora users should download and install the Fedora RPM for Fedora 19 and 20, or run:
     # Fedora users only
     sudo yum install http://packages.2ndquadrant.com/postgresql-bdr94-2ndquadrant/yum-repo-rpms/postgresql-bdr94-2ndquadrant-fedora-latest.noarch.rpm
It is strongly recommended that you also enable the corresponding repository from yum.postgresql.org, as the BDR repositories only contain the BDR extension and the PostgreSQL server, client, PLs, and the rest of the core PostgreSQL release. They do not contain PostGIS, PgBarman, or any of the other components already included in yum.postgresql.org releases. BDR is fully compatible with these components.
Red Hat / CentOS users should also enable EPEL. Installing PostgreSQL 9.4 and BDR from packages for RHEL, Fedora or CentOS Remove the postgresql94 packages, if installed

Note: If you don't already have PostgreSQL 9.4 installed, simply skip this step.
BDR requires a patched version of PostgreSQL 9.4 that conflicts with the official packages from yum.postgresql.org. If you already have PostgreSQL 9.4installed from yum.postgresql.org, you will need to make a dump of all your databases, then uninstall the PGDG PostgreSQL 9.4 packages before you can install BDR
The BDR RPMs cannot co-exist with stock PostgreSQL 9.4, and BDR does not share the same data directory as stock 9.4, so it will not be able to read your existing databases. (They will not be deleted, and uninstalling BDR then reinstalling stock PGDG 9.4 will get you access to them again, but it is strongly recommended that you dump them before installing BDR).
Once you have fully backed up all your databases:
      yum remove postgresql94\*
Check the list of packages to be removed carefully, approve the removal if appropriate, and proceed with the removal.
Your data directory for PostgreSQL 9.4 will still exist in /var/lib
