If you’re encountering a database error after installing Roundcube on Ubuntu 24.04, it typically indicates an issue with the connection between Roundcube and your database (usually MySQL/MariaDB). Below are the steps to troubleshoot and resolve the issue:
1. Verify Database Configuration
Roundcube requires a properly configured database connection. Check the Roundcube configuration file to ensure the database settings are correct.
-> Open the Roundcube configuration file:
sudo nano /var/www/roundcube/config/config.inc.php
-> Look for the following lines and ensure they match your database settings:
<?php $config['db_dsnw'] = 'mysql://roundcubeuser:password@localhost/roundcubedb'; ?>
Replace:
-> `roundcubeuser` with your database username.
-> `password` with your database password.
-> `roundcubedb` with your database name.
Save the file and exit (`Ctrl + X`, then `Y` to confirm).
2. Check Database Credentials
Ensure the database user and database exist and have the correct permissions.
-> Log in to MySQL/MariaDB:
sudo mysql -u root -p
-> Verify the database and user:
```sql SHOW DATABASES; SELECT User, Host FROM mysql.user;
-> If the database or user doesn’t exist, create them:
```sql CREATE DATABASE roundcubedb; CREATE USER 'roundcubeuser'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON roundcubedb.* TO 'roundcubeuser'@'localhost'; FLUSH PRIVILEGES;
3. Test Database Connection
Manually test the database connection to ensure Roundcube can connect.
-> Install the MySQL client (if not already installed):
```bash sudo apt install mysql-client ```
-> Test the connection:
```bash mysql -u roundcubeuser -p -h localhost roundcubedb ```
Enter the password when prompted. If you can connect, the issue is likely with Roundcube’s configuration.
4. Check Database Schema
Roundcube requires a specific database schema. If the schema isn’t initialized, you’ll encounter errors.
-> Import the Roundcube database schema:
```bash sudo mysql -u root -p roundcubedb < /var/www/roundcube/SQL/mysql.initial.sql ```
-> If you’re using a different database (e.g., PostgreSQL), use the corresponding schema file.
5. Check Logs for Errors
Inspect the Roundcube and database logs for more details about the error.
-> Roundcube logs:
```bash sudo nano /var/www/roundcube/logs/errors.log ```
-> MySQL/MariaDB logs:
```bash sudo tail -f /var/log/mysql/error.log ```
6. Verify PHP Extensions
Roundcube requires specific PHP extensions for database connectivity. Ensure they are installed and enabled.
-> Install required PHP extensions:
```bash sudo apt install php-mysql php-json php-xml php-mbstring php-intl php-zip ```
-> Restart the web server:
```bash sudo systemctl restart apache2 ```
7. Check Web Server Permissions
Ensure the web server has the necessary permissions to access the Roundcube directory.
-> Set correct permissions:
```bash sudo chown -R www-data:www-data /var/www/roundcube sudo chmod -R 755 /var/www/roundcube ```
8. Reinstall Roundcube (Optional)
If the issue persists, consider reinstalling Roundcube.
-> Remove Roundcube:
```bash sudo rm -rf /var/www/roundcube ```
-> Reinstall Roundcube:
```bash sudo apt install roundcube roundcube-core roundcube-mysql ```
9. Common Errors and Fixes
-> Error: “Database connection failed”:
– Verify the database credentials in `config.inc.php`.
– Ensure the database server is running:
```bash sudo systemctl status mysql ```
-> Error: “Table not found”:
– Import the Roundcube database schema as described in Step 4.
