Instalasi Redis di MacOS X tanpa brew
Apabila anda belum memiliki brew atau ingin mengkompilasi sendiri redis, anda bisa mengunduh Redis dari situs Redis. Saat tulisan ini dibuat versi stabil terbaru adalah redis-2.8.19. Anda bisa menggunakan command curl dibawah ini untuk mengunduh versi terbaru Redis, saya akan mengunduh di folder Download didalam home directory saya
$ cd ~/Downloads
$ curl -o redis-2.8.19.tar.gz http://download.redis.io/releases/redis-2.8.19.tar.gz

Setelah proses mengunduh Redis selesai anda bisa mengekstrak file terkompres yang baru saja anda unduh dan mulai mengkompilasi. Saya berasumsi bahwa anda sudah melakukan instalasi XCode atau compiler lain di computer anda.
$ tar xzvf redis-2.8.19.tar.gz
$ cd redis-2.8.19
$ make test
...
