OpenEMR Dependencies

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:

openemr-4.2.1.tar.gz (MD5 sum: 62e16a011a02a37c732397c9576d5984 )

2. Next, Extract the downloaded archive:

tar -pxvzf openemr-4.2.1.tar.gz

3. Move the extracted openemr-4.2.1 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, Ubuntu's webserver root directory is /var/www, so in Ubuntu you would use the following commands:

mv openemr-4.2.1 /var/www/openemr

cd /var/www

Some other common webserver root directories are:

• Mandriva: /var/www/html/
• The FHS: /srv/www/
