One time machine security config #vim /etc/selinux/config Set SELINUX=permissive #setenforce 0 #getenforce This should return "Permissive" If firewall is there Allow http/https/MySQL Traffic

Configure PHP #vim /etc/php.ini short_open_tag = on max_input_vars = 100000 upload_max_filesize = 36M post_max_size = 36M memory_limit = 1024M max_execution_time=60 Seach for and add the following line: cgi.fix_pathinfo=0

Enable and start Apache #systemctl start httpd #systemctl enable httpd

Check Versions #php -v #httpd -v

Create test files #cd /var/www/html

#vim info.php

Put below code in info.php file to get information about PHP7.

Check in browser by visiting url and if works we will proceed to next steps.

Restart Apache #systemctl restart httpd

Application Install

Copy all application files into /var/www/html/

Change owner of files #cd imwemr/ #chown -R apache.apache cache/ #chown -R apache.apache iMedicMonitor/cache/ #chown -R apache.apache data

Permissions on SigPlus #cd /var/www/html/ #chown -R apache.apache SigPlusLinuxHSB

------Sigplus is signature application -----------

Import IMW Databases (Clean Database for New Clients) We have created 3 Databases main database is demo_imw, for scanned document data its demo_imw_scan database and demo_scemr for surgery center database. These databases are clean databases which will enough to start provisioning new client and ready to go with production. From database folder restore all these databases in MySQL server and set user with appropriate permissions.

Set up a site to with Subdomain setup #cd /var/www/html/imwemr/config

Edit globals.php accordingly.

#vim globals.php $RootDirectoryName = "imwemr"; $webServerRootDirectoryName = "/var/www/html/" define('PRODUCT_VERSION_DATE', 'Jan 24, 2021 - V1.0.0'); //April 24, 2020

Create the config folder for the site #cd /var/www/html/imwemr/config #mkdir -p demo #cd demo/ #vim config_demo.php

     $myInternalIP = "demo.yourdomain.com";
     $myExternalIP = "demo.yourdomain.com";
     $phpServerIP = "demo.yourdomain.com";

     Also modify DB connections
     $sqlconf = array();
     $sqlconf["host"]= 'db-cluster.host';
     $sqlconf["port"] = '3306';
     $sqlconf["login"] = 'imw_user';
     $sqlconf["pass"] = 'password1';
     $sqlconf['idoc_db_name'] = 'demo_imwemr';
     $sqlconf['scan_db_name'] = 'demo_imwemr_scan';

Create apache config file for site #cd /etc/httpd/conf.d #vim demo.conf <VirtualHost *:80> DocumentRoot "/var/www/html/imwemr" ServerName demo.yourdomain.com

Restart apache #systemctl restart httpd

Test Application Go to URL and test application and login Username: demo Password: P@ssw0rd1

Optical Setup

#cd /var/www/html/demo_optical

Edit config.php -- Go to config directory, copy sample file, edit it #cd /var/www/html/demo_optical/config

#vim config.php Edit the config file and change the following three variables to the Site-Specific values: $host='demo.yourdomain.com'; $GLOBALS['DIR_PATH']="/var/www/html/demo_optical"; $GLOBALS['IMW_DIR_PATH']= "/var/www/html/imwemr"; $GLOBALS['SUB_DOMAIN']="demo";

$GLOBALS['IMW_DB_NAME'] = "demo_imw"; $sqlconf["host"]= 'yourdatabaseserverhostname'; $sqlconf["port"] = '3306'; $sqlconf["login"] = 'mysql_user'; $sqlconf["pass"] = 'mysqluserpassword';

Assign file permissions #cd /var/www/html/demo_optical #chown -R apache.apache interface/patient_interface/uploaddir/ #chown -R apache.apache images/ #chown -R apache.apache library/new_html2pdf/

Modify config file to enable Optical icon in EMR/PM #cd /var/www/html/imwemr/config/demo #vim config_demo.php

Uncomment this line and set the directory name to “optical” $GLOBALS['optical_directory_name'] = "optical";// Optical Directory Name

Uncomment the following line as well define("connect_optical","1");//IF connect_optical VALUE IS 1 THEN Optical Functionality WILL BE Work in iDOC.

Copy .htaccess file from imwemr directory #cp /var/www/html/imwemr/.htaccess /var/www/html/demo_optical/

Edit apache config to enable Aliases. Reload Apache #vim /etc/httpd/conf.d/demo.conf

Remove comment under <VirtualHost 172.31.100.131:80> Alias /optical /var/www/html/demo_optical

Reload apache #service httpd reload

Test Application Go to URL and test application and login Username: demo Password: P@ssw0rd1

We can change password from application even from mysql tables (SHA256) based password used with lower case. Go to any online password website and generate your own password.

IASCEMR Setup

Configure SurgeryCenter to connect to IMWEMR #cd /var/www/html/demo_iascemr/ #vim connect_imwemr.php Configure to connect to demo_imwemr $imw_db_name = 'demo_imwemr'; $imw_host = 'mysqlserverhostnameorip'; $imw_port = '3306'; $imw_login = 'mysql_user'; $imw_pass = 'password1';

Configure IMW to connection to SC #cd /var/www/html/imwemr/config/demo #vim config_demo.php Uncomment the SC connection info at bottom of file and fill in DB name: ['sc_db_name'] = 'demo_scemr'; $sqlconf['sc_db_name'] = 'demo_scemr';

Configure SurgeryCenter #cd /var/www/html/demo_iascemr/common #vim conDb.php

  $asc_db_name = 'demo_scemr';
  $asc_host = 'mysqlhostnameorip';
  $asc_port = '3306';
  $asc_login = 'mysql_user';
  $asc_pass = 'password1';

  $surgeryCenterDirectoryName='demo_iascemr';
  $iolinkDirectoryName='demo_iasclink';
  $imwPracticeName='demo';
  
  Also change “imwDirectoryName”. This name should be same as of Root Dir of EHR/PM.
  $imwDirectoryName='imwemr';

Assign File Permissions cd /var/www/html/demo_iascemr chown -R apache.apache new_html2pdf chown -R apache.apache html2pdf chown -R apache.apache xml chown -R apache.apache SigPlus_images chown -R apache.apache sx_grid_images chown -R apache.apache pdf chown -R apache.apache html2pdfnew chown -R apache.apache testPdf.html chown -R apache.apache white.jpg chown -R apache.apache crons/logs chown -R apache.apache admin/pdfFiles chown apache.apache new_html2pdf_reports chown apache.apache new_html2pdf_reports/.jpg chown apache.apache new_html2pdf_reports/.html

Reload the apache service #service httpd reload

Go to the url and test and login SurgeryCenter is not integrated with main application so visit according to Alias. for example : demo.yourdomain.com/iascemr/ Username: admin Password: P@ssw0rd1

IASCLink Setup

Configure IASCLink to connect to IMW #cd /var/www/html/demo_iasclink/ #vim connect_imwemr.php Configure to connect to demo_imwemr $imw_db_name = 'demo_imwemr'; $imw_host = 'mysqlhostnameorip'; $imw_port = '3306'; $imw_login = 'mysql_user'; $imw_pass = 'password1';

  $surgeryCenterDirectoryName='demo_iascemr';
  $iolinkDirectoryName='demo_iasclink';
  $imwPracticeName='demo';
  
  Also change “imwDirectoryName”. This name should be same as of Root Dir of EHR/PM.
  $imwDirectoryName='imwemr';

Set permissions cd /var/www/html/demo_iasclink chown -R apache.apache html2pdfnew chown -R apache.apache imedic_uploaddir chown -R apache.apache SigPlus_images chown -R apache.apache new_html2pdf chown -R apache.apache new_html2pdf/pdffile.html chown -R apache.apache testPdf.html chown -R apache.apache pdfSplit chown -R apache.apache admin/pdfFiles

Reload the apache service #service httpd reload

Enable the iASCLink in EMR #cd /var/www/html/imwemr/config/demo #vim config_demo.php Change value of $GLOBALS['iasclink_directory_name'] to "iasclink" $GLOBALS['iasclink_directory_name'] = "iasclink";// iASCLink Directory Name

Go to url and test and login with Username: iolink Password: P@ssw0rd1

Notes :

1. There are additional software needed for scanning and other equipments, get vendor support for that.
2. Any PHP error, enable php log within each pages or globally.
3. Password can be change both from application and MySQL tables usualy in "users" table.
