<p><b>New page</b></p><div>Bayangkan kalian punya 30 teman di kelas, tapi semuanya tidak punya nama. Kalau Pak Guru mau panggil satu orang, pasti bingung kan? Harus tunjuk-tunjuk atau panggil "Woy kamu!".<br />
<br />
Nah, komputer di jaringan juga begitu. '''Hostname''' itu ibarat '''Nama Panggilan''' atau '''Name Tag''' untuk komputer kalian.<br />
<br />
* Tanpa hostname yang jelas, kita bakal pusing membedakan mana komputer server, mana komputer klien, atau mana komputer guru.<br />
* Secara bawaan (default), biasanya namanya cuma "debian". Kita akan ubah jadi nama yang lebih keren atau sesuai fungsi, misalnya <code>server-sekolah</code>.<br />
<br />
Gampang kok, cuma butuh edit 2 file saja. Yuk, kita mulai!<br />
<br />
== Langkah-Langkah Konfigurasi ==<br />
Pastikan kalian sudah login sebagai '''root''' (Super User) ya, yang tandanya pagar (<code>#</code>), bukan dollar (<code>$</code>).<br />
<br />
=== 1. Cek Nama Saat Ini ===<br />
Sebelum diganti, kita lihat dulu nama aslinya apa. Ketik perintah ini:<br />
<code>hostname</code><br />
Biasanya akan muncul tulisan <code>debian</code>.<br />
<br />
=== 2. Edit "KTP" Komputer (/etc/hostname) ===<br />
Langkah pertama, kita ubah file identitas utamanya. File ini isinya cuma satu kata, yaitu nama komputer itu sendiri.<br />
<br />
* Ketik perintah untuk membuka file:<br />
** ''(Catatan: Kalau kalian belum bisa pakai vim, bisa pakai nano juga).''<br />
<br />
* Hapus nama lama (misalnya <code>debian</code>), lalu ganti dengan nama baru, contohnya: <code>server-sekolah</code>.<br />
* Simpan dan keluar.<br />
<br />
=== 3. Edit "Buku Alamat" Komputer (/etc/hosts) ===<br />
Setelah ganti nama di KTP, kita harus update buku alamat sistem biar komputer sadar kalau nama dia sudah berubah. Kalau tidak diganti, komputer bisa "bingung" saat memanggil dirinya sendiri.<br />
<br />
* Buka file hosts:<br />
* Kalian akan melihat baris seperti ini: <code>127.0.0.1 localhost</code> <code>127.0.1.1 debian</code> <-- Nah, baris kedua ini yang perlu diubah.<br />
* Ganti kata <code>debian</code> (nama lama) menjadi <code>server-sekolah</code> (nama baru).<br />
* Formatnya biasanya begini: <code>[IP Address] [Nama Domain] [Hostname]</code>. Contoh: <code>192.168.10.1 sekolah.edu server-sekolah</code>.<br />
* Simpan dan keluar.<br />
<br />
=== 4. Aktifkan Perubahan ===<br />
Nama sudah diganti di file, tapi sistem yang sedang berjalan belum sadar kalau namanya berubah. Kita perlu "menyentil" sistemnya biar sadar.<br />
<br />
* Ketik perintah ini:<br />
* Atau kalau mau cara paling pasti, restart saja komputernya:<br />
<br />
=== 5. Verifikasi (Cek Ulang) ===<br />
Setelah aktif, coba cek lagi apakah namanya sudah berubah.<br />
<br />
* Ketik lagi:<br />
<br />
<code>hostname</code><br />
<br />
* Kalau yang muncul adalah <code>server-sekolah</code>, berarti selamat! Kalian sukses memberi nama pada server kalian.</div>
