Koneksi VPS dengan SSH Tanpa Password
Pengguna VPS pasti akrab dengan yang namanya SSH atau Secure Shell. Sistem koneksi terminal versi aman dari Telnet ini merupakan satu-satunya pilihan untuk manajemen VPS.
Pada umumnya, untuk menjalankan sesi SSH, dibutuhkan SSH Client seperti PuTTY. Setelah menginisiasi koneksi ke server, kita diminta user dan password. Tentu ini memakan waktu beberapa saat. Saya termasuk orang yang tidak terlalu suka ribet. Maka dari itu saya setel saja SSH ke VPS saya dengan sistem private key, tanpa password.
Login VPS dengan SSH tanpa password
Saya akan memberi contoh menggunakan Windows 8 sebagai SSH client. Untuk itu perlu disiapkan bahan-bahan sebagai berikut:
- PuTTY sebagai aplikasi client SSH
- PuTTY Key Generator untuk membuat private key
- Secangkir teh hangat dan cemilan
Langkah-langkah untuk login SSH tanpa password diantaranya sebagai berikut:
- Buka PuTTY Key Generator. Lalu tekan tombol Generate. Ada semacam progress bar yang muncul. Gerakkan mouse dibawah progress bar tersebut, di area kosong, sampai progress bar penuh dan berganti menjadi seperti gambar dibawah ini.
Proses pembuatan private key.
- Klik Save private key, lalu simpan file berekstensi .ppk tersebut di folder yang aman, namun mudah anda temukan.
- Jangan tutup dulu jendela Puttygen tersebut. Pada bagian Public key, yang isinya karakter-karakter ga jelas itu klik kanan lalu pilih menu Select All, klik kanan lagi lalu pilih Copy.
Puttygen menghasilkan public key
- Buka PuTTY lalu login ke VPS. Ketik
nano ./.ssh/authorized_keyslalu tekan enter. Seharusnya anda mendapati file itu kosong. Tinggal arahkan pointer mouse ke layar PuTTY lalu klik kanan.
Ketik exit di shell untuk logout dari VPS. Nah, sekarang urusan dengan public key sudah beres. Saatnya setting PuTTY supaya bisa login SSH tanpa password ke VPS, hanya menggunakan key tadi.
- Buka PuTTY, lalu klik tanda + di bagian Connection. Selanjutnya klik Data. Isikan user name seperti gambar dibawah ini.
Setting PuTTY login data dengan username VPS. Biasanya sih root. 🙂
- Setelah itu klik tanda + di bagian SSH, lalu klik Auth. Nah, silahkan setting sesuai gambar dibawah ini.
Tambahkan file PPK yang sudah disimpan tadi. Masih inget kan lokasinya?
Setelah itu seharusnya anda sudah bisa login SSH tanpa password ke VPS anda, seperti gambar dibawah ini:
Putty bisa login ssh tanpa password ke VPS saya.
Jangan lupa untuk menyimpan setting PuTTY, ya. Kalo cara simpannya tentu anda sudah tahu, kan? Oh ya, cara ini baiknya hanya dilakukan di komputer private, entah itu laptop atau PC yang khusus anda gunakan sendiri. Ada pertanyaan? Silahkan di kolom komentar.
