Basic XOOPS Configuration

This guide covers essential configuration settings to get your XOOPS site running properly after installation.

mainfile.php Configuration

The mainfile.php file contains critical configuration for your XOOPS installation. It’s created during installation but you may need to edit it manually.

Location

/var/www/html/xoops/mainfile.php

File Structure

<?php
// Database Configuration
define('XOOPS_DB_TYPE', 'mysqli');  // Database type
define('XOOPS_DB_HOST', 'localhost');  // Database host
define('XOOPS_DB_USER', 'xoops_user');  // Database user
define('XOOPS_DB_PASS', 'password');  // Database password
define('XOOPS_DB_NAME', 'xoops_db');  // Database name
define('XOOPS_DB_PREFIX', 'xoops_');  // Table prefix

// Site Configuration
define('XOOPS_ROOT_PATH', '/var/www/html/xoops');  // File system path
define('XOOPS_URL', 'http://your-domain.com/xoops');  // Web URL
define('XOOPS_TRUST_PATH', '/var/www/html/xoops/var');  // Trusted path

// Character Set
define('XOOPS_DB_CHARSET', 'utf8mb4');  // Database charset
define('_CHARSET', 'UTF-8');  // Page charset

// Debug Mode (set to 0 in production)
define('XOOPS_DEBUG', 0);  // Set to 1 for debugging
?>

Critical Settings Explained

`XOOPS_DB_TYPE`	Database system	`mysqli`, `mysql`, `pdo`
`XOOPS_DB_HOST`	Database server location	`localhost`, `192.168.1.1`
`XOOPS_DB_USER`	Database username	`xoops_user`
`XOOPS_DB_PASS`	Database password	[secure_password]
`XOOPS_DB_NAME`	Database name	`xoops_db`
`XOOPS_DB_PREFIX`	Table name prefix	`xoops_` (allows multiple XOOPS on one DB)

`XOOPS_URL`	Web accessible URL	`http://your-domain.com`
`XOOPS_TRUST_PATH`	Trusted path (outside web root)	`/var/www/xoops_var`

Editing mainfile.php

Open mainfile.php in a text editor:

# Using nano
nano /var/www/html/xoops/mainfile.php

# Using vi
vi /var/www/html/xoops/mainfile.php

# Using sed (find and replace)
sed -i "s|define('XOOPS_URL'.*|define('XOOPS_URL', 'http://new-domain.com');|" /var/www/html/xoops/mainfile.php

Common mainfile.php Changes

Change site URL:

define('XOOPS_URL', 'https://yourdomain.com');

Enable debug mode (development only):

define('XOOPS_DEBUG', 1);

Change table prefix (if needed):

define('XOOPS_DB_PREFIX', 'myxoops_');

Move trust path outside web root (advanced):

define('XOOPS_TRUST_PATH', '/var/www/xoops_var');

Admin Panel Configuration

Configure basic settings through the XOOPS admin panel.

Accessing System Settings

Log in to admin panel: http://your-domain.com/xoops/admin/
Navigate to: System > Preferences > General Settings
Modify settings (see below)
Click “Save” at bottom

Site Name and Description

Configure how your site appears:

Site Name: My XOOPS Site
Site Description: A dynamic content management system
Site Slogan: Built with XOOPS

Contact Information

Set site contact details:

Site Admin Email: admin@your-domain.com
Site Admin Name: Site Administrator
Contact Form Email: support@your-domain.com
Support Email: help@your-domain.com

Language and Region

Set default language and region:

Default Language: English
Default Timezone: America/New_York  (or your timezone)
Date Format: %Y-%m-%d
Time Format: %H:%M:%S

Email Configuration

Configure email settings for notifications and user communications.

Email Settings Location

Admin Panel: System > Preferences > Email Settings

SMTP Configuration

For reliable email delivery, use SMTP instead of PHP mail():

Use SMTP: Yes
SMTP Host: smtp.gmail.com  (or your SMTP provider)
SMTP Port: 587  (TLS) or 465 (SSL)
SMTP Username: your-email@gmail.com
SMTP Password: [app_password]
SMTP Security: TLS or SSL

Gmail Configuration Example

Set up XOOPS to send email via Gmail:

SMTP Host: smtp.gmail.com
SMTP Port: 587
SMTP Security: TLS
SMTP Username: your-email@gmail.com
SMTP Password: [Google App Password - NOT regular password]
From Address: your-email@gmail.com
From Name: Your Site Name

Note: Gmail requires an App Password, not your Gmail password:

Go to https://myaccount.google.com/apppasswords
Generate app password for “Mail” and “Windows Computer”
Use the generated password in XOOPS

PHP mail() Configuration (Simpler but Less Reliable)

If SMTP unavailable, use PHP mail():

Use SMTP: No
From Address: noreply@your-domain.com
From Name: Your Site Name

Ensure your server has sendmail or postfix configured:

# Check if sendmail is available
which sendmail

# Or check postfix
systemctl status postfix

Email Function Settings

Configure what triggers emails:

Send Notifications: Yes
Notify Admin on User Registration: Yes
Send Welcome Email to New Users: Yes
Send Password Reset Link: Yes
Enable User Email: Yes
Enable Private Messages: Yes
Notify on Admin Actions: Yes

Timezone Configuration

Set proper timezone for correct timestamps and scheduling.

Setting Timezone in Admin Panel

Path: System > Preferences > General Settings

Default Timezone: [Select your timezone]

Common Timezones:

America/New_York (EST/EDT)
America/Chicago (CST/CDT)
America/Denver (MST/MDT)
America/Los_Angeles (PST/PDT)
Europe/London (GMT/BST)
Europe/Paris (CET/CEST)
Asia/Tokyo (JST)
Asia/Shanghai (CST)
Australia/Sydney (AEDT/AEST)

Verify Timezone

Check current server timezone:

# Show current timezone
timedatectl

# Or check date
date +%Z

# List available timezones
timedatectl list-timezones

Set System Timezone (Linux)

# Set timezone
timedatectl set-timezone America/New_York

# Or use symlink method
ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime

# Verify
date

URL Configuration

Enable Clean URLs (Friendly URLs)

For URLs like /page/about instead of /index.php?page=about

Requirements:

Apache with mod_rewrite enabled
.htaccess file in XOOPS root

Enable in Admin Panel:

Go to: System > Preferences > URL Settings
Check: “Enable Friendly URLs”
Select: “URL Type” (Path Info or Query)
Save

Verify .htaccess Exists:

cat /var/www/html/xoops/.htaccess

Sample .htaccess content:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /xoops/
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?$1 [L,QSA]
</IfModule>

Troubleshooting Clean URLs:

# Verify mod_rewrite enabled
apache2ctl -M | grep rewrite

# Enable if needed
a2enmod rewrite

# Restart Apache
systemctl restart apache2

# Test rewrite rule
curl -I http://your-domain.com/xoops/index.php

Configure Site URL

$mailer = xoops_getMailer();
$mailer->addRecipient('admin@your-domain.com');
$mailer->setSubject('XOOPS Email Test');
$mailer->setBody('This is a test email from XOOPS');

if ($mailer->send()) {
    echo "Email sent successfully!";
} else {
    echo "Failed to send email: " . $mailer->getError();
}
?>

Test Database Connection

<?php
require_once __DIR__ . '/mainfile.php';

$connection = XoopsDatabaseFactory::getDatabaseConnection();
if ($connection) {
    echo "Database connected successfully!";
    $result = $connection->query("SELECT COUNT(*) FROM " . $connection->prefix("users"));
