Pada artikel ini, kami akan menjelaskan langkah-langkah yang diperlukan untuk menginstal dan mengkonfigurasi ClamAV di Ubuntu 20.04 LTS. Sebelum melanjutkan tutorial ini, pastikan Anda login sebagai pengguna dengan sudo hak istimewa. Semua perintah dalam tutorial ini harus dijalankan sebagai pengguna non-root.
ClamAV adalah alat Antivirus sumber terbuka yang tersedia untuk distribusi Linux. Ini mengintegrasikan server Mail untuk memindai lampiran yang diterima. Fungsi lain juga termasuk pemindaian web. ClamAV menyertakan daemon pemindai multi-utas, utilitas baris perintah untuk pemindaian file sesuai permintaan dan pembaruan tanda tangan otomatis. Salah satu kegunaan utamanya adalah pada server email sebagai pemindai virus email sisi server.
Instal ClamAV di Ubuntu 20.04
Langkah 1. Pertama, sebelum Anda mulai menginstal paket apa pun di server Ubuntu Anda, kami selalu menyarankan untuk memastikan bahwa semua paket sistem telah diperbarui.
sudo apt update sudo apt upgrade
Langkah 2. Instal ClamAV di sistem Ubuntu.
Repositori default Ubuntu 20.04 berisi versi rilis stabil terbaru dari ClamAV. Anda cukup menginstalnya menggunakan perintah berikut:
sudo apt install clamav clamav-daemon
Setelah paket berhasil diinstal, jalankan perintah berikut untuk memeriksa apakah paket telah diinstal atau belum:
clamscan --version
Langkah 3. Perbarui Basis Data ClamAV.
Pertama, hentikan clamav-freshclam service (jika sedang berjalan) dan jalankan freshclam , alat pembaruan basis data virus:
sudo systemctl stop clamav-freshclam
Kemudian, perbarui basis data virus:
freshclam
Selanjutnya, mulai layanan clamav-freshclam dan aktifkan untuk memulai saat reboot sistem dengan perintah berikut:
sudo systemctl start clamav-freshclam sudo systemctl enable clamav-freshclam
Langkah 4. Gunakan Clamscan untuk Memindai.
Sintaks dasar Clamscan ditunjukkan di bawah ini:
clamscan [options] [files-or-directories]
Anda dapat mencetak semua opsi yang tersedia dengan clamscan menggunakan perintah berikut:
clamscan -h
