Instalasi dan Konfigurasi LAMP Stack untuk Menjalankan WordPress di AlmaLinux

 

Panduan Instalasi LAMP + WordPress 

Versi ini ditata ulang total dengan desain clean putih-biru agar terlihat profesional dan tidak mirip sumber lain.

1. Persiapan Sistem

Update Sistem

sudo dnf update -y

Melakukan pembaruan paket agar sistem stabil dan kompatibel.

Install LAMP Stack

sudo dnf install httpd mariadb-server mariadb php php-mysqlnd php-fpm -y

• httpd → Apache Web Server
• mariadb-server → Server database
• php & php-mysqlnd → PHP & driver MariaDB
• php-fpm → Handler PHP berbasis FastCGI

Aktifkan Layanan

sudo systemctl enable --now httpd
sudo systemctl enable --now mariadb
sudo systemctl enable --now php-fpm

2. Konfigurasi MariaDB

Amankan MariaDB

sudo mysql_secure_installation

Buat Database & User

CREATE DATABASE wordpress CHARACTER SET utf8mb4;
CREATE USER 'wpuser'@'localhost' IDENTIFIED BY 'wpuser123';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wpuser'@'localhost';
FLUSH PRIVILEGES;

Jika user sudah ada

ALTER USER 'wpuser'@'localhost' IDENTIFIED BY 'wpuser123';
FLUSH PRIVILEGES;

3. Upload & Ekstrak WordPress

sudo mv latest.tar.gz /var/www/
cd /var/www
sudo tar -xvzf latest.tar.gz
sudo chown -R apache:apache wordpress
sudo chmod -R 755 wordpress

Jika ada instalasi lama:

sudo mv /var/www/wordpress /var/www/wordpress_old

4. Konfigurasi Apache

Contoh Virtual Host:

<VirtualHost *:80>
  ServerName 123.456.789.101
  DocumentRoot /var/www/wordpress

  <Directory /var/www/wordpress>
    AllowOverride All
    Require all granted
  </Directory>

  ErrorLog /var/log/httpd/wordpress_error.log
  CustomLog /var/log/httpd/wordpress_access.log combined
</VirtualHost>

Aktifkan mod_rewrite

sudo dnf install mod_rewrite -y
sudo systemctl restart httpd

5. Konfigurasi PHP-FPM

sudo nano /etc/php-fpm.d/www.conf

Pastikan isinya:

listen = /run/php-fpm/www.sock
listen.owner = apache
listen.group = apache
listen.mode = 0660
user = apache
group = apache

Tambahkan handler PHP:

<FilesMatch \.php$>
  SetHandler "proxy:unix:/run/php-fpm/www.sock|fcgi://localhost/"
</FilesMatch>

6. SELinux & Firewall

sudo chcon -R -t httpd_sys_rw_content_t /var/www/wordpress
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

7. Troubleshooting

Masalah	Penyebab	Solusi
Service Unavailable	Apache tidak terhubung dengan PHP-FPM	Periksa socket & pastikan php-fpm berjalan
Error DB Connection	User / password salah	Cek wp-config.php & akses MariaDB
Forbidden	Permission atau SELinux	Gunakan chown / chcon

8. Testing WordPress
