Just noticed that apt-get install redis-server will only work on koala or newer, but with a redis-server.deb package
its easy too…

wget http://ftp.us.debian.org/debian/pool/main/r/redis/redis-server_2.2.2-1_i386.deb
#http://ftp.us.debian.org/debian/pool/main/r/redis/redis-server_2.2.2-1_amd64.deb
sudo dpkg -i redis-server_2.2.2-1_i386.deb
