Configuring Zend
PHP
Need to use php version 5.3.3 or greater.
Apache
This section is to document best way to configure Zend with apache. It appears following two things need to be completed in apache for zend stuff to work:
- enable "rewrite" mod in apache
- allow "AllowOverride" in apache
- There are some security considerations here(this allows use of .htaccess files). Ideally would have following set up:
- Apache's main config file would turn this off.
- Turn this on in OpenEMR directory
- Turn this off in the OpenEMR directories that allow uploaded files (such as sites/default/documents)
- Need to test above setup and if works, then need to place in the setup.php instructions and also set up for the ubuntu/mint/debian package.
- There are some security considerations here(this allows use of .htaccess files). Ideally would have following set up:
Above is discussed on the following threads:
TO DO
- Document how to get Zend configured for all OS's (see above "Configuring Zend" section for details).
