How to Fix UniFi Controller Cannot locate Java Home

How to Fix UniFi Controller Cannot locate Java Home [ fail ]
Untuk langkah-langkah instalasi unifi bisa lihat disini
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

* Starting Ubiquiti UniFi Controller unifi  Cannot locate Java Home    [fail]

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

JAVA_HOME=/usr/lib/jvm/java-6-openjdk/

dan ganti dengan ini ( directory java yang terpasang di ubuntu 12.04 )

JAVA_HOME=/usr/lib/jvm/java-6-openjdk-i386

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 )

Jika sudah berhasil langsung saja buka browser dan ketikan alamat ini untuk masuk ke unifi controller yang sudah kita install

https://(ip pc anda):8080

hasil nya seperti gambar berikut, anda bisa langsung login dan konfigurasi unifi

sekian dari saya,
Selamat mencoba dan Semoga bermanfaat.
