OpenEMR 4.0 Linux Installation

Required Software Installation (distribution specific)

First install and configure MySQL, Apache (or another PHP-capable webserver), and PHP5. We recommend referring to your specific operating system (OS) documentation for installation of these software packages.

Debian Lenny

To install the prerequisite software on debian, use the APT system as the system administrator:

apt-get install mysql-server apache2-mpm-prefork libapache2-mod-php5 php5-mysql

Centos Or RedHat

If using CentOS or Redhat, then ensure when configuring MySQL for OpenEMR, STRICT_MODE must be disabled. This can be done in the MySQL configuration (my.cnf) file. You can check the setting in an existing MySQL instance by executing SHOW VARIABLES; in the MySQL Command Line Client and checking the value of SQL_MODE. For more details see: http://dev.mysql.com/doc/refman/5.0/en/server-sql-mode.html)

Installing OpenEMR

Extracting the Tarball

1. First, Download OpenEMR from sourceforge:

http://downloads.sourceforge.net/openemr/openemr-4.0.0.tar.gz (MD5 sum: PENDING RELEASE)

2. Next, Extract the downloaded archive:

tar -pxvzf openemr-4.0.0.tar.gz

3. Move the extracted openemr-3.2.0 directory to your webserver root directory, and then go to this directory. Refer to your OS and webserver documentation to obtain you webserver root directory. For example, Mandriva's webserver root directory is /var/www/html, so in mandriva you would use the following commands:

mv openemr-4.0.0 /var/www/html/openemr

cd /var/www/html

Some other common webserver root directories are:

• Debian: /var/www/
• The FHS: /srv/www/

Cleaning up FileSystem Permissions

1. Modify file permissions (this should be done as root user):

chmod 666 openemr/library/sqlconf.php

2. Modify directory permissions. We need to make the following directories writable by the webserver username. The webserver username is dependent on your OS; "apache", "www-data", and "nobody" are some common examples. Mandriva's webserver username is "apache", so in mandriva you would use the following commands (this should be done as root user):

chown -R apache:apache openemr/sites/default/documents

chown -R apache:apache openemr/sites/default/edi

chown -R apache:apache openemr/sites/default/era

chown -R apache:apache openemr/sites/default/letter_templates

chown -R apache:apache openemr/library/freeb

chown -R apache:apache openemr/gacl/admin/templates_c

chown -R apache:apache openemr/interface/main/calendar/modules/PostCalendar/pntemplates/cache

chown -R apache:apache openemr/interface/main/calendar/modules/PostCalendar/pntemplates/compiled

Configuring the Install through the WEB GUI

1. Open up web-browser and point it to the installation script at http://localhost/openemr/setup.php .

The first screen gives some general instructions and ensures file and directory permissions are set up correctly. It should tell you all your file system permissions are good, and have a 'Continue' button on the bottom of the form. If it does, Click the 'Continue' button. Otherwise, If there are errors on this screen, then follow instructions to fix. (screenshot below)
