<p>
To use the yum repository, you must first install the <i>repository RPM</i>.
To do this, download the correct RPM from the
<a href="https://yum.postgresql.org/repopackages.php">repository RPM listing</a>,
and install it with commands like:
</p>
<p>
On RHEL and its derivatives:
<code>
yum install https://yum.postgresql.org/9.6/redhat/rhel-7-x86_64/pgdg-redhat96-9.6-3.noarch.rpm
</code>
</p>
<p>
On Fedora,
<code>
dnf install https://download.postgresql.org/pub/repos/yum/9.6/fedora/fedora-25-x86_64/pgdg-fedora96-9.6-3.noarch.rpm
</code>
</p>
<p>
Once this is done, you can proceed to install and update packages the
same way as the ones included in the distribution.
</p>
<p>
For RHEL and its derivatives:
<code>
yum install postgresql96-server postgresql96-contrib<br/>
(or yum groupinstall "PostgreSQL Database Server 9.6 PGDG")<br/>
service postgresql-9.6 initdb<br/>
chkconfig postgresql-9.6 on
service postgresql-9.6 start
</code>
or, on Fedora 24 and other later derived distributions:<br />
<code>
dnf install postgresql96-server postgresql96-contrib<br/>
(or dnf groupinstall "PostgreSQL Database Server 9.6 PGDG")<br/>
/usr/pgsql-9.6/bin/postgresql96-setup initdb<br/>
systemctl enable postgresql-9.6.service<br/>
systemctl start postgresql-9.6.service
</code>

Package names in the
PostgreSQL yum repository follows the same standard as the ones included
in the main repositories, but include the version number, such as:
To use the yum repository, follow these steps:

<li>Select platform: <select id="platform" onChange="platChanged()"></select></li>
<li>Select architecture: <select id="arch" onChange="archChanged()"></select></li>
<li>Install the repository RPM:
<code id="reporpm"></code>
</li>
<li>Install the client packages:
<code id="clientpackage"></code>
</li>
<li>Optionally install the server packages:
<code id="serverpackage"></code>
