Migrating to Azure App Service (Linux) install problems

[fredbob]

Hi All,

Just wondering if anyone has succ essfully run ProcessWire on an Azure App Service, Linux not Windows. Started off with a fresh install:

1. Uploaded site files
2. Setup Azure MySQL server
3. Ran installer

During the installer I get this error:

Warning: ini_set(): Headers already sent. You cannot change the session module's ini settings at this time in /home/site/wwwroot/wire/core/Session.php on line 247
Warning: session_name(): Cannot change session name when headers already sent in /home/site/wwwroot/wire/core/Session.php on line 251

Then I proceed to login

ProcessWire: ProcessLogin: This request was aborted because it appears to be forged.

• I've changed permissions
• Checked .htaccess
• Set PHP session path
• Azure - ARR affinity (Improve performance of your stateless app by turning Affinity Cookie off, stateful apps should keep this setting on for compatibility. Learn more)
• Azure - Always on (Prevents your app from being idled out due to inactivity)

Envirnomnet

• Web Server - Azure App Service (Linux) https://docs.microsoft.com/en-us/azure/app-service/containers/
• PHP - 7.2 (7.2-apache), also tried 7.3 (7.3-apache)
• MySQL - 5.7 https://docs.microsoft.com/en-us/azure/mysql/

If anyone has gotten this to work some pointers would be great! I've decided I don't want to run it on a Windows App Service, as I would have to convert .htaccess to web.config and ProcessWire is designed and supported for Apache / Linux web servers.

Any help is appreciated!

Hi xfroggy,

Just had this same problem and resolved it by setting the sessions path in config.php to /tmp:

$config->paths->sessions = '/tmp';

Hope this helps.
