Answer 1

Have you installed redis?

Installing REDIS on Ubuntu

Ref: http://redis.io/download

1. Download, extract and compile Redis with:-

   $ cd ~/Installations
   $ curl -O http://redis.googlecode.com/files/redis-2.2.1.tar.gz
   $ tar xzf redis-2.2.1.tar.gz
   $ cd redis-2.2.1
   $ sudo make
   

2. Install Tcl (the Tool Command Language) runtime

   $ sudo apt-get install tcl8.5
   

3. Running Redis Server

   $ src/redis-server
   [31371] 24 Feb 10:14:03 # Warning: no config file specified, using the default config. In order to   specify a config file use 'redis-server /path/to/redis.conf'
   [31371] 24 Feb 10:14:03 * Server started, Redis version 2.2.1
   [31371] 24 Feb 10:14:03 # WARNING overcommit_memory is set to 0! Background save may  fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
