+# Install Redis on old distributions
+
+GitLab requires at least Redis 2.8. The following guide is for Debian 7 and
+Ubuntu 12.04. If you are using Debian 8 or Ubuntu 14.04 and up, follow the
+[installation guide](installation.md).
+
+## Install Redis 2.8 in Debian 7
+
+Redis 2.8 is included in the Debian Wheezy [backports] repository.
+
+1. Edit `/etc/apt/sources.list` and add the following line:
+
+    ```
+    deb http://http.debian.net/debian wheezy-backports main
+    ```
+
+1. Update the repositories:
+
+    ```
+    sudo apt-get update
+    ```
+
+1. Install `redis-server`:
+
+    ```
+    sudo apt-get -t wheezy-backports install redis-server
+    ```
+
+1. Follow the rest of the [installation guide](installation.md).
+
+## Install Redis 2.8 in Ubuntu 12.04
+
+We will [use a PPA](https://launchpad.net/~chris-lea/+archive/ubuntu/redis-server)
+to install a recent version of Redis.
+
+1. Install the PPA repository:
+
+    ```
+    sudo add-apt-repository ppa:chris-lea/redis-server
+    ```
+
+    Your system will now fetch the PPA's key. This enables your Ubuntu system to
+    verify that the packages in the PPA have not been interfered with since they
+    were built.
+
+1. Update the repositories:
+
+    ```
+    sudo apt-get update
+    ```
+
+1. Install `redis-server`:
+
+    ```
+    sudo apt-get install redis-server
+    ```
+
+1. Follow the rest of the [installation guide](installation.md).
