CentOS/RHEL Installation

This guide will help you install Poweradmin on CentOS, RHEL, and other RHEL-based distributions like Rocky Linux or AlmaLinux.

Prerequisites

Ensure you have the following PHP extensions installed:

dnf install -y php php-intl php-gettext php-pdo php-fpm

Database Support

Install the appropriate PHP database driver based on your preferred database:

# For MySQL/MariaDB
dnf install -y php-mysqlnd

# For PostgreSQL
dnf install -y php-pgsql

# For SQLite (if available in your repositories)
dnf install -y php-sqlite3

Web Server Configuration

Apache

1. Install Apache if not already installed: bash dnf install -y httpd

2. Enable and start the Apache service: bash systemctl enable httpd systemctl start httpd

3. Configure SELinux if it's enabled: ```bash # Allow Apache to connect to the database setsebool -P httpd_can_network_connect_db 1

# If using a non-standard directory, set the correct context semanage fcontext -a -t httpd_sys_content_t "/path/to/poweradmin(/.*)?" restorecon -Rv /path/to/poweradmin ```

1. Configure your firewall: bash firewall-cmd --permanent --add-service=http firewall-cmd --permanent --add-service=https # If using HTTPS firewall-cmd --reload

Nginx Configuration

If you prefer Nginx:

1. Install Nginx: bash dnf install -y nginx

2. Create a configuration file for Poweradmin:

server {
    listen 80;
    server_name localhost; # Replace with your domain

    root /var/www/html; # Path to Poweradmin files
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php-fpm/www.sock;  # RHEL/CentOS path
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_index index.php;
    }

    # Deny access to .htaccess and .htpasswd files for security reasons
    location ~ /\.ht {
        deny all;
    }
}

1. Save this file to /etc/nginx/conf.d/poweradmin.conf

2. Enable and start Nginx and PHP-FPM: bash systemctl enable nginx php-fpm systemctl start nginx php-fpm

3. Configure SELinux and firewall as with Apache.

Installing Poweradmin

Obtain Poweradmin Source Code

Download the latest release (v3.9.2) from GitHub Releases:

curl -Lo v3.9.2.zip https://github.com/poweradmin/poweradmin/archive/refs/tags/v3.9.2.zip
unzip v3.9.2.zip

If you don't have curl or unzip installed:

dnf install -y curl unzip

Deploy to Web Server

Move the Poweradmin files to your web server's document root:

# For Apache (default directory)
cp -r poweradmin-3.9.2/* /var/www/html/
chown -R apache:apache /var/www/html/

# For Nginx (if using a different directory)
cp -r poweradmin-3.9.2/* /usr/share/nginx/html/
chown -R nginx:nginx /usr/share/nginx/html/

Complete the Installation

1. Visit http://your-server/install/ in your browser
2. Follow the installation steps
3. Once installation is complete, remove the install directory for security
4. Log in with the admin username and password created during installation

Troubleshooting

If you encounter issues:

• Check PHP error logs: /var/log/php-fpm/www-error.log
• Check web server logs: /var/log/httpd/error_log or /var/log/nginx/error.log
• Ensure SELinux permissions are properly set if SELinux is enabled
• Verify all required PHP extensions are installed and enabled
• Check that file permissions are correct for your web server user
