OpenMRS or Open Medical Record System is a Java based collaborative open source project used to create customized medical records system with no programming knowledge.
To install OpenMRS on a CentOS VPS follow the very easy steps described below. OpenMRS requires Java 6, Java servlet container such as Apache Tomcat, and an existing database such as MySQL.
Install Java 6 using the following command:
yum install java-1.6.0-openjdk java-1.6.0-openjdk-devel ant
Verify the Java version installed on the server:
java -version java version "1.6.0_33" OpenJDK Runtime Environment (IcedTea6 1.13.5) (rhel-126.96.36.199.el6_6-x86_64) OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)
Download and install the latest version of Apache Tomcat 7 (do not install Tomcat 8 if you intend to use it with Java 6):
cd /opt wget http://www.webhostingreviewjam.com/mirror/apache/tomcat/tomcat-7/v7.0.57/bin/apache-tomcat-7.0.57.tar.gz tar -zxf apache-tomcat-7.0.57.tar.gz -C /usr/local mv /usr/local/apache-tomcat-7.0.57 /usr/local/tomcat useradd -r tomcat --shell /bin/false chown -R tomcat: /usr/local/tomcat
Edit the ‘/usr/local/tomcat/bin/catalina.sh’ file and add the following line before ‘# OS specific support. $var _must_ be set to either true or false.’ line:
For advanced users using OpenMRS in production it is recommended to download OpenMRS Platform 1.10.1 WAR file. It can be downloaded at http://openmrs.org/download/
cd /usr/local/tomcat/webapps wget http://sourceforge.net/projects/openmrs/files/releases/OpenMRS_Platform_1.10.1/openmrs.war/download -O openmrs.war mkdir -P /usr/local/tomcat/.OpenMRS chown tomcat: /usr/local/tomcat/webapps/openmrs.war chown tomcat: /usr/local/tomcat/.OpenMRS/
Since ‘openmrs.war’ file is located to the ‘/usr/local/tomcat/webapps’ directory, it will automatically be deployed by Tomcat on start-up, so start Tomcat service:
cd /usr/local/tomcat/bin ./startup.sh
OpenMRS requires a database to work as this is where data is saved, so create a new ‘openmrsdb’ MySQL database on your server:
mysql -u root -p mysql> CREATE DATABASE openmrsdb; mysql> CREATE USER [email protected]; mysql> SET PASSWORD FOR 'openmrs'@'localhost' = PASSWORD("openmrs-password"); mysql> GRANT ALL PRIVILEGES ON openmrsdb.* TO 'openmrs'@'localhost' IDENTIFIED BY 'openmrs-password' WITH GRANT OPTION; mysql> FLUSH PRIVILEGES; mysql> quit
Open http://server-ip-address:8080/openmrs and follow the easy instructions: select install language, choose ‘Advanced’ type of installation, enter ‘openmrsdb’ as database name, ‘openmrs’ as MySQL username and the MySQL password for the ‘openmrs’ user defined earlier and finally specify a new password for your administrator user.
If you like to eliminate the 8080 from the URL and open OpenMRS through a regular URL (i.e. reverse proxy OpenMRS web application behind Apache), edit Apache configuration file and add the following lines:
<VirtualHost *:80> ServerAdmin [email protected] ServerName your-domain.com ErrorLog logs/your-domain.com-error_log CustomLog logs/your-domain.com-access_log common ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://server-ip-address:8080/openmrs/ ProxyPassReverse / http://server-ip-address:8080/openmrs/ <Location /> Order allow,deny Allow from all </Location>
In order to open OpenMRS using http://your-domain.com , change ‘server-ip-address’ with ‘your-domain.com’ in the ProxyPass and ProxyPassReverse directives. Do not forget to restart Apache web server for the changes to take effect:
service httpd restart
That is it. The OpenMRS installation is now complete. Of course you don’t have to do any of this if you use one of our Super-Fast CentOS Hosting services, in which case you can simply ask our expert Linux admins to install OpenMRS for you. They are available 24×7 and will take care of your request immediately.
