-## 5. Set Permissions
 
-Ensure Apache can access the RCDB files:
-
-```bash
-# Check ownership of the directory
-ls -la /group/halld/www/halldwebdev/html/rcdb/
-
-# Set appropriate permissions
-sudo chown -R apache:apache /group/halld/www/halldwebdev/html/rcdb/
-# OR add read permissions for others
-sudo chmod -R o+r /group/halld/www/halldwebdev/html/rcdb/
-sudo chmod o+x /group/halld/www/halldwebdev/html/rcdb/
-```

-## 6. Configure SELinux (if enabled)
-
-If SELinux is enabled on your system:
-
-```bash
-# Allow Apache to connect to the database
-sudo setsebool -P httpd_can_network_connect_db 1
-
-# Set proper context for the WSGI file
-sudo chcon -t httpd_sys_content_t /group/halld/www/halldwebdev/html/rcdb/rcdb_www.wsgi
-```
-
-## 7. Restart Apache
+## 5. Restart Apache
 
 ```bash
 sudo systemctl restart httpd
 ```
 
-## 8. Test the Installation
-
-Visit `http://your-server/rcdb` in your web browser.
-
-If you encounter issues, check the Apache error logs:
-
-```bash
-sudo tail -f /var/log/httpd/error_log
-```
-
-## Troubleshooting
-
-### Missing Modules
-
-If you encounter missing module errors, install them with pip:
-
-```bash
-# For system-wide installation
-sudo pip3 install flask sqlalchemy pymysql
-
-# For virtual environment
-source /group/halld/www/halldwebdev/html/rcdb/venv/bin/activate
-pip install flask sqlalchemy pymysql
-deactivate
-```
-
-### Permissions Issues
-
-If you see permission denied errors:
-
-```bash
-# Check SELinux status
-sestatus
-
-# If SELinux is enforcing, try setting it to permissive temporarily for testing
-sudo setenforce 0
-
-# After testing, remember to set it back to enforcing
-sudo setenforce 1
-```
-
-### Database Connection Issues
-
-If the website loads but database connection fails:
-
-1. Verify your connection string in the Apache config and WSGI script
-2. Check if the database server allows connections from your web server
-3. Test the connection manually:
-
-```bash
-python3 -c "import pymysql; pymysql.connect(host='hallddb.jlab.org', user='rcdb', db='rcdb2')"
-```
-
 ## Additional Notes
 
 - The RCDB web interface requires the proper database schema to be installed
