OpenEMR 4.2.1 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.
- (Ensure PHP V5.4 or higher, is configured with these settings)
To install the prerequisite software on debian, use the APT system as the system administrator to install packages listed on following wiki page section:
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)
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/
