Troubleshooting¶

Running the web server troubleshooter¶

A web server troubleshooting tool is available at http://YOUR_HOST/myamiweb/test/checkwebserver.php.
You can browse to this page from the Appion and Leginon Tools home page (http://YOUR_HOST/myamiweb) by clicking on [test Dataset] and then [Troubleshoot].

This page will automatically confirm that your configuration file and PHP installation and settings are correct and point you to the appropriate documentation to correct any issues.

Firewall settings¶

You may need to configure your firewall to allow incoming HTTP (port 80) and MySQL (port 3306) traffic:

$ system-config-securitylevel

Security-enhanced linux¶

Security-enhanced linux may be preventing your files from loading. To fix this run the following command:

$ sudo /usr/bin/chcon -R -t httpd_sys_content_t /var/www/html/
