Untuk instalasi unifi ini saya terapkan di linux ubuntu 12.04
Langsung saja ke pokok permasalahan, setelah unifi berhasil terinstall pada terminal muncul seperti ini

tapi tenang saja, itu terjadi karena kesalahan pada konfigurasi unifi

Bagaimana cara memperbaiki kesalahan konfig unifi ??
Langsung saja buka terminal anda dan ketikan perintah berikut, anda bisa menggunakan editor lain nya
sudo gedit /etc/init.d/unifi
kemudian cari
dan ganti dengan ini ( directory java yang terpasang di ubuntu 12.04 )
atau anda pastikan dahulu dimana directory java yg terinstall di pc anda
Jika sudah jangan lupa save
Untuk menjalankan unifi ketikan perintah berikut
sudo /etc/init.d/unifi start
Untuk mematikan unifi ketikan perintah berikut

sudo /etc/init.d/unifi stop
Hasil nya seperti gambar berikut ( unifi controller OK )
