System Requirements


  • HTTP Server. For example: Apache.

  • PHP 5.3.0+. (Preferred: PHP 5.4.16+)
  • MySQL 4+ (Preferred:5.1.10+)
  • PDO PHP Module for MySQL
  • XML RPC Extension for PHP (for Groups Integration) - Not required for latest version.


 You might need to disable the: sql_mode=only_full_group_by which is enabled by default in MySQL 5.7.5+


Note: People are using GrassBlade LRS on Nginx, IIS (on hosts like Azure). So the above requirements are more of recommendations. 


Recommendations for IIS/Windows Server: 

- You might need to disable WebDAV module. It blocks PUT requests, and some content that send PUT requests will not work. Generally, it can be disabled using web.config file. Sometimes you need to make other adjustments to enable PUT requests. 
- There is a sample web.config file included in grassblade-lrs


Recommendations for NGINX: 
- NGINX doesn't use .htaccess but uses a nginx.conf file. There is a sample nginx.conf file in grassblade-lrs, you can use it as reference to configure your NGINX server for URL rewrites. 




Popular Hosting Services Used for GrassBlade LRS:
