• Coronavirus disease 2019

    COVID-19 is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic.

    The symptoms of COVID‑19 can vary but often include fever,[7] fatigue, cough, breathing difficulties, loss of smell, and loss of taste.[8][9][10] Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.[11][12] Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction).[13] Older people have a higher risk of developing severe symptoms. Some complications result in death. Some people continue to experience a range of effects (long COVID) for months or years after infection, and damage to organs has been observed.[14] Multi-year studies on the long-term effects are ongoing.[15]

    COVID‑19 transmission occurs when infectious particles are breathed in or come into contact with the eyes, nose, or mouth. The risk is highest when people are in close proximity, but small airborne particles containing the virus can remain suspended in the air and travel over longer distances, particularly indoors. Transmission can also occur when people touch their eyes, nose, or mouth after touching surfaces or objects that have been contaminated by the virus. People remain contagious for up to 20 days and can spread the virus even if they do not develop symptoms.[16]

    Testing methods for COVID-19 to detect the virus’s nucleic acid include real-time reverse transcription polymerase chain reaction (RT‑PCR),[17][18] transcription-mediated amplification,[17][18][19] and reverse transcription loop-mediated isothermal amplification (RT‑LAMP)[17][18] from a nasopharyngeal swab.[20]

    Several COVID-19 vaccines have been approved and distributed in various countries, many of which have initiated mass vaccination campaigns. Other preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, use of face masks or coverings in public, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face. While drugs have been developed to inhibit the virus, the primary treatment is still symptomatic, managing the disease through supportive care, isolation, and experimental measures.

  • Panduan Lengkap: Cara Install LAMP Stack & WordPress di Ubuntu 24.04 LTS

    Cara Install LAMP Stack dan WordPress di Ubuntu 24.04 LTS (Langkah demi Langkah)

    Membuat situs web WordPress mandiri (self-hosted) membutuhkan fondasi server yang stabil. Kombinasi yang paling populer dan tepercaya adalah LAMP Stack (Linux, Apache, MySQL, PHP).

    Panduan ini akan menuntun Anda menginstal LAMP Stack di Ubuntu 24.04 LTS (Noble Numbat) hingga situs WordPress Anda siap digunakan.

    Prasyarat

    • Server dengan OS Ubuntu 24.04 LTS.
    • Akses root atau pengguna dengan hak akses sudo.
    • Domain yang sudah diarahkan (pointed) ke Alamat IP server Anda (opsional, namun sangat disarankan).

    Langkah 1: Update Server

    Sebelum menginstal paket baru, pastikan indeks repositori sistem Anda dalam kondisi paling segar.

    sudo apt update && sudo apt upgrade -y

    Langkah 2: Install Web Server Apache

    Apache bertugas melayani halaman web saat ada pengunjung yang mengakses server Anda.

    1. Jalankan perintah instalasi Apache:

    sudo apt install apache2 -y

    2. Aktifkan dan pastikan Apache berjalan:

    sudo systemctl enable --now apache2

    3. Buka akses port HTTP (80) dan HTTPS (443) di firewall:

    sudo ufw allow 'Apache Full'

    Verifikasi: Buka browser dan ketik Alamat IP server Anda (http://alamat_ip_server). Jika berhasil, Anda akan melihat halaman Apache2 Ubuntu Default Page.

    Langkah 3: Install Database Server MySQL

    WordPress menggunakan database relasional untuk menyimpan semua postingan, halaman, komentar, dan pengaturan situs.

    1. Install MySQL Server:

    sudo apt install mysql-server -y

    2. Jalankan skrip keamanan bawaan MySQL:

    sudo mysql_secure_installation
    • Validate Password Component? Ketik Y jika ingin kebijakan kata sandi ketat, atau N jika tidak.
    • Atur kata sandi untuk akun root MySQL.
    • Jawab Y (Yes) untuk semua pertanyaan keamanan berikutnya (menghapus pengguna anonim, mematikan login root jarak jauh, dan menghapus database tes).

    Langkah 4: Install PHP dan Ekstensi Pendukung

    PHP adalah bahasa pemrograman tempat WordPress dibangun.

    1. Install PHP beserta modul pendukung yang dibutuhkan WordPress:

    sudo apt install php libapache2-mod-php php-mysql php-curl php-gd php-mbstring php-xml php-xmlrpc php-soap php-intl php-zip -y

    2. Verifikasi versi PHP:

    php -v

    3. Konfigurasi dir.conf agar Apache mendahulukan file index.php:

    sudo nano /etc/apache2/mods-enabled/dir.conf

    Ubah urutannya hingga index.php berada tepat setelah DirectoryIndex:

    <IfModule mod_dir.c>
        DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm
    </IfModule>

    Simpan dengan menekan Ctrl + O, Enter, lalu keluar dengan Ctrl + X.

    4. Restart Apache untuk menerapkan perubahan:

    sudo systemctl restart apache2

    Langkah 5: Buat Database dan Pengguna MySQL

    Buka terminal MySQL untuk membuat wadah penyimpanan data khusus WordPress.

    1. Masuk ke prompt MySQL:

    sudo mysql

    2. Jalankan perintah SQL berikut (Ganti db_wordpress, wp_user, dan Password_Kuat_Anda123! sesuai keinginan Anda):

    CREATE DATABASE db_wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;
    CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'Password_Kuat_Anda123!';
    GRANT ALL PRIVILEGES ON db_wordpress.* TO 'wp_user'@'localhost';
    FLUSH PRIVILEGES;
    EXIT;

    Langkah 6: Unduh dan Konfigurasi WordPress

    1. Pindah ke direktori sementara dan unduh paket berkas resmi WordPress:

    cd /tmp
    curl -O https://wordpress.org/latest.tar.gz

    2. Ekstrak file berkas tersebut:

    tar xzvf latest.tar.gz

    3. Buat file .htaccess dan siapkan file konfigurasi:

    touch /tmp/wordpress/.htaccess
    cp /tmp/wordpress/wp-config-sample.php /tmp/wordpress/wp-config.php

    4. Salin seluruh direktori WordPress ke direktori web Apache:

    sudo cp -a /tmp/wordpress/. /var/www/html/wordpress

    5. Atur Hak Akses dan Kepemilikan (Penting untuk Keamanan):

    sudo chown -R www-data:www-data /var/www/html/wordpress
    sudo find /var/www/html/wordpress/ -type d -exec chmod 750 {} \;
    sudo find /var/www/html/wordpress/ -type f -exec chmod 640 {} \;

    6. Konfigurasi wp-config.php:

    Buka file konfigurasi untuk menghubungkan WordPress ke database MySQL:

    sudo nano /var/www/html/wordpress/wp-config.php

    Cari baris berikut dan isi sesuai detail database yang dibuat pada Langkah 5:

    define( 'DB_NAME', 'db_wordpress' );
    define( 'DB_USER', 'wp_user' );
    define( 'DB_PASSWORD', 'Password_Kuat_Anda123!' );
    define( 'DB_HOST', 'localhost' );

    Simpan dan keluar (Ctrl + O, Enter, Ctrl + X).

    Langkah 7: Konfigurasi Virtual Host Apache

    1. Buat file konfigurasi Virtual Host baru:

    sudo nano /etc/apache2/sites-available/wordpress.conf

    2. Tambahkan konfigurasi berikut (Ganti domainanda.com dengan nama domain Anda atau Alamat IP Server):

    <VirtualHost *:80>
        ServerAdmin admin@domainanda.com
        ServerName domainanda.com
        ServerAlias www.domainanda.com
        DocumentRoot /var/www/html/wordpress
    
        <Directory /var/www/html/wordpress/>
            AllowOverride All
            Require all granted
        </Directory>
    
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
    </VirtualHost>

    3. Aktifkan site baru dan modul mod_rewrite:

    sudo a2ensite wordpress.conf
    sudo a2enmod rewrite

    4. Nonaktifkan konfig bawaan Apache dan tes konfigurasi:

    sudo a2dissite 000-default.conf
    sudo apache2ctl configtest

    5. Restart Apache:

    sudo systemctl restart apache2

    Langkah 8: Selesaikan Instalasi Lewat Browser Web

    1. Buka browser Anda dan kunjungi domain atau Alamat IP server Anda:

    http://domainanda.com

    2. Anda akan disambut oleh Halaman Instalasi Visual WordPress:

    • Pilih Bahasa: Pilih Bahasa Indonesia dan klik Lanjutkan.
    • Informasi Situs: Isi Judul Situs, Nama Pengguna (Username Admin), Sandi, dan Alamat Email Anda.
    • Klik tombol Install WordPress.

    3. Setelah selesai, klik Log Masuk dan masukkan username serta password yang baru saja dibuat.


    Penutup

    Selamat! Anda telah berhasil membangun Stack LAMP dan menginstal WordPress di server Ubuntu 24.04 LTS.
