  1. Directories. Create /opt/sana if it does not exist. This will be the document root where the mds urls and files get served from.
    • mkdir -p /opt/sana/sana.mds/cache
    • mkdir -p /opt/sana/sana.mds/cache/static
    • mkdir -p /opt/sana/sana.mds/cache/media
  2. Database. Create the mds database and set up access.Use your own credentials instead of **** below.
    • Open a MySQL prompt.

      mysql -u root -p CREATE DATABASE mds; CREATE USER ‘mds’@’localhost’ IDENTIFIED BY ‘**’; GRANT ALL ON mds.* TO ‘mds’@’localhost’; exit;

MDS Installation

  1. MDS source code

    mkdir ~/git cd ~/git git clone https://github.com/SanaMobile/sana.mds.git

  2. Link or copy the mds source into the sana directories

    ln -s /home/<user>/git/sana.mds/src/mds /opt/sana/sana.mds/mds
    cp -r /home/<user>/git/sana.mds/src/mds /opt/sana/sana.mds
    cp /home/<user>/git/sana.mds/src/manage.py /opt/sana/sana.mds  
    

    Note: Linking is preferable to keep any files cached at runtime out of the source directories.

  3. MDS set up.
    • Install and set up the mds code

      cp /opt/sana/sana.mds/mds/settings.py.tmpl /opt/sana/sana.mds/mds/settings.py cp /opt/sana/sana.mds/mds/local_settings.py.tmpl /opt/sana/sana.mds/mds/local_settings.py

    • Adjust any values in settings.py to match the local system. Should just be the database config.

      cd /opt/sana/sana.mds
      python manage.py syncdb
      python manage.py collectstatic
      
    • Link the contents of /opt/sana/sana.mds/mds/ to your apache document root. The default for Ubuntu is /var/www/html, e.g.

      ln -sf /opt/sana/sana.mds/mds /var/www/html/mds
      
  4. Directory Permissions. Update directory permissions for the mds files

    chown -R www-data:www-data /opt/sana/sana.mds

  5. Apache configuration for MDS
    • Set mds environment variables

      echo ‘export MDS_DIR=/opt/sana/sana.mds’ » /etc/apache2/envvars

    • Copy the mds.conf file from the source into the apache conf-available directory and enable.

      cp /home//git/sana.mds/include/mds/apache2/conf-available/* \ /etc/apache2/conf-available

    • Add option to follow symlinks for the server root directive in your apache config, example:

      <Directory /var/www/html> Options FollowSymLinks Require all granted </Directory>

    • Enable mds conf

      a2enconf mds

    • Enable wsgi module

      a2enmod wsgi

  6. Set up encryption. (https://help.ubuntu.com/14.04/serverguide/certificates-and-security.html) This is not absolutely required for development servers. The following is a quick start for generating your own certificate.

    • Create your own certificate and key

      openssl genrsa -des3 -out server.key 1024 openssl rsa -in server.key -out server.key.insecure openssl req -new -key server.key -out server.csr openssl x509 -req -days 365 -in server.csr -signkey server.key.insecure -out server.crt

      You will be prompted for some information. Type in country, state, city, org, common name. You can skip challenge password and company name)

    • Copy the cert and key

      cp server.crt /etc/ssl/certs cp server.key /etc/ssl/private

  7. Restart Apache and check connection:

    service apache2 restart

    You should now be able to access:

    http://<hostname>/mds/
    https://<hostname>/mds/
    

OpenMRS Installation

Ignore the following steps if running MDS in standalone mode.

  1. Configure Tomcat.
    • Verify that the following line is in your /etc/tomcat7/server.xml file, uncomment if necessary.

       <Connector port="8009" URIEncoding="UTF-8" enableLookups="false" protocol="AJP/1.3" />
      

    A sample server.xml is available in the mds includes directory. Create OpenMRS installation directory

    mkdir /usr/share/tomcat7/.OpenMRS
    chown tomcat7:tomcat7 /usr/share/tomcat7/.OpenMRS
    

    e. Restart tomcat. service tomcat7 restart

  2. Enable apache modules and and openmrs conf

    a2enmod jk
    a2enmod proxy
    a2enmod proxy_http
    a2enmod proxy_ajp
    a2enconf openmrs
    

    Note: Step (b) will provide access to OpenMRS through http:///openmrs
