Step-by-Step Installation

Step 1: Download XOOPS

Download the latest version from https://xoops.org/:

# Using wget
wget https://xoops.org/download/xoops-2.5.8.zip

# Using curl
curl -O https://xoops.org/download/xoops-2.5.8.zip

Step 2: Extract Files

Extract the XOOPS archive to your web root:

# Navigate to web root
cd /var/www/html

# Extract XOOPS
unzip xoops-2.5.8.zip

# Rename folder (optional, but recommended)
mv xoops-2.5.8 xoops
cd xoops

Step 3: Set File Permissions

Set proper permissions for XOOPS directories:

# Make directories writable (755 for dirs, 644 for files)
find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

# Make specific directories writable by web server
chmod 777 uploads/
chmod 777 templates_c/
chmod 777 var/
chmod 777 cache/

# Secure mainfile.php after installation
chmod 644 mainfile.php

Step 4: Create Database

Create a new database for XOOPS using MySQL:

-- Create database
CREATE DATABASE xoops_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

-- Create user
CREATE USER 'xoops_user'@'localhost' IDENTIFIED BY 'secure_password_here';

-- Grant privileges
GRANT ALL PRIVILEGES ON xoops_db.* TO 'xoops_user'@'localhost';
FLUSH PRIVILEGES;

Or using phpMyAdmin:

1. Log in to phpMyAdmin
2. Click “Databases” tab
3. Enter database name: xoops_db
4. Select “utf8mb4_unicode_ci” collation
5. Click “Create”
6. Create a user with the same name as database
7. Grant all privileges

Step 5: Run Installation Wizard

Open your browser and navigate to:

http://your-domain.com/xoops/install/

System Check Phase

The wizard checks your server configuration:

• PHP version >= 5.6.0
• MySQL/MariaDB available
• Required PHP extensions (GD, PDO, etc.)
• Directory permissions
• Database connectivity

If checks fail:

See #Common-Installation-Issues section for solutions.

Database Configuration

Enter your database credentials:

Database Host: localhost
Database Name: xoops_db
Database User: xoops_user
Database Password: [your_secure_password]
Table Prefix: xoops_

Important Notes:

• If your database host differs from localhost (e.g., remote server), enter the correct hostname
• The table prefix helps if running multiple XOOPS instances in one database
• Use a strong password with mixed case, numbers, and symbols

Admin Account Setup

Create your administrator account:

Admin Username: admin (or choose custom)
Admin Email: admin@your-domain.com
Admin Password: [strong_unique_password]
Confirm Password: [repeat_password]

Best Practices:

• Use a unique username, not “admin”
• Use a password with 16+ characters
• Store credentials in a secure password manager
• Never share admin credentials

Module Installation

Choose default modules to install:

• System Module (required) - Core XOOPS functionality
• User Module (required) - User management
• Profile Module (recommended) - User profiles
• PM (Private Message) Module (recommended) - Internal messaging
• WF-Channel Module (optional) - Content management

Select all recommended modules for a complete installation.

Step 6: Complete Installation

After all steps, you’ll see a confirmation screen:

Installation Complete!

Your XOOPS installation is ready to use.
Admin Panel: http://your-domain.com/xoops/admin/
User Panel: http://your-domain.com/xoops/

Step 7: Secure Your Installation

Remove Installation Folder

# Remove the install directory (CRITICAL for security)
rm -rf /var/www/html/xoops/install/

# Or rename it
mv /var/www/html/xoops/install/ /var/www/html/xoops/install.bak

WARNING: Never leave the install folder accessible in production!

Secure mainfile.php

# Make mainfile.php read-only
chmod 644 /var/www/html/xoops/mainfile.php

# Set ownership
chown www-data:www-data /var/www/html/xoops/mainfile.php

Set Proper File Permissions

# Recommended production permissions
find . -type f -name "*.php" -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;

# Writable directories for web server
chmod 777 uploads/ var/ cache/ templates_c/

Enable HTTPS/SSL

Configure SSL in your web server (nginx or Apache).

For Apache:

<VirtualHost *:443>
    ServerName your-domain.com
    DocumentRoot /var/www/html/xoops

    SSLEngine on
    SSLCertificateFile /etc/ssl/certs/your-cert.crt
    SSLCertificateKeyFile /etc/ssl/private/your-key.key

    # Force HTTPS redirect
    <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteCond %{HTTPS} off
        RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
    </IfModule>
</VirtualHost>

Post-Installation Configuration

1. Access Admin Panel

Navigate to:

http://your-domain.com/xoops/admin/

Login with your admin credentials.

2. Configure Basic Settings

Configure the following:

• Site name and description
• Admin email address
• Timezone and date format
• Search engine optimization

3. Test Installation

• Visit homepage
• Check modules load
• Verify user registration works
• Test admin panel functions
• Confirm SSL/HTTPS works

4. Schedule Backups

Set up automatic backups:

# Create backup script (backup.sh)
#!/bin/bash
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/backups/xoops"
XOOPS_DIR="/var/www/html/xoops"

# Backup database
mysqldump -u xoops_user -p[password] xoops_db > $BACKUP_DIR/db_$DATE.sql

# Backup files
tar -czf $BACKUP_DIR/files_$DATE.tar.gz $XOOPS_DIR

echo "Backup completed: $DATE"

Schedule with cron:

# Daily backup at 2 AM
0 2 * * * /usr/local/bin/backup.sh

Common Installation Issues

Issue: Permission Denied Errors

Symptom: “Permission denied” when uploading or creating files

Solution:

# Check web server user
ps aux | grep apache  # For Apache
ps aux | grep nginx   # For Nginx

# Fix permissions (replace www-data with your web server user)
chown -R www-data:www-data /var/www/html/xoops
chmod -R 755 /var/www/html/xoops
chmod 777 uploads/ var/ cache/ templates_c/

Issue: Database Connection Failed

Symptom: “Cannot connect to database server”

Solution:

1. Verify database credentials in the installation wizard
2. Check MySQL/MariaDB is running:

   service mysql status  # or mariadb

3. Verify database exists:

   SHOW DATABASES;

4. Test connection from command line:

   mysql -h localhost -u xoops_user -p xoops_db

Issue: Blank White Screen

Symptom: Visiting XOOPS shows blank page

Solution:

1. Check PHP error logs:

   tail -f /var/log/apache2/error.log

2. Enable debug mode in mainfile.php:

   define('XOOPS_DEBUG', 1);

3. Check file permissions on mainfile.php and config files
4. Verify PHP-MySQL extension is installed

Issue: Cannot Write to Uploads Directory

Symptom: Upload feature fails, “Cannot write to uploads/”

Solution:

# Check current permissions
ls -la uploads/

# Fix permissions
chmod 777 uploads/
chown www-data:www-data uploads/

# For specific files
chmod 644 uploads/*

Issue: PHP Extensions Missing

Symptom: System check fails with missing extensions (GD, MySQL, etc.)

Solution (Ubuntu/Debian):

# Install PHP GD library
apt-get install php-gd

# Install PHP MySQL support
apt-get install php-mysql

# Restart web server
systemctl restart apache2  # or nginx

Solution (CentOS/RHEL):

# Install PHP GD library
yum install php-gd

# Install PHP MySQL support
yum install php-mysql

# Restart web server
systemctl restart httpd

Issue: Slow Installation Process

Symptom: Installation wizard times out or runs very slowly

Solution:

1. Increase PHP timeout in php.ini:

   max_execution_time = 300  # 5 minutes

2. Increase MySQL max_allowed_packet:

   SET GLOBAL max_allowed_packet = 256M;

3. Check server resources:

   free -h  # Check RAM
   df -h    # Check disk space

Issue: Admin Panel Not Accessible

Symptom: Cannot access admin panel after installation

Solution:

1. Verify admin user exists in database:

   SELECT * FROM xoops_users WHERE uid = 1;

2. Clear browser cache and cookies
3. Check if sessions folder is writable:

   chmod 777 var/

4. Verify htaccess rules don’t block admin access

Verification Checklist

After installation, verify:

• XOOPS homepage loads correctly
• Admin panel is accessible at /xoops/admin/
• SSL/HTTPS is working
• Install folder is removed or inaccessible
• File permissions are secure (644 for files, 755 for dirs)
• Database backups are scheduled
• Modules load without errors
• User registration system works
• File upload functionality works
• Email notifications send properly

Next Steps

Once installation is complete:

1. Read Basic Configuration guide
