Configuring SSL

Getting SSL certificate

A An SSL certificate is issued by a Certificate Authority (CA). Your internal IT/IS team might be able to help you with this. You might have to submit the basic information in the form of CSR (Certificate Signing Request). Refer this page to regenerate CSR: https://in.godaddy.com/help/generating-a-certificate-signing-request-csr-apache-2x-5269

...

  1. Copy the certificate files to ${apache_home}/conf/CSR/

  2. Open "${apache_home}/conf/httpd.conf" file 

  3. Search for the "LoadModule ssl_module modules/mod_ssl.so" and remove

    1. Remove any pound sign(#) at the start of the line (i.e.

    un-comment it
    1. uncomment it)

    2. If this line is not found in the file, then it means SSL module is not installed. Please install this depending on the OS of the server

      For CentOS - yum install mod_ssl

  4. Skip 5th step if you installed SSL module manually i.e (3.b)
  5. Add below section at the end of the file httpd.conf file after replacing the dummy values with the real one. 

    Code Block
    Listen 443
    <VirtualHost *:443>
        DocumentRoot "D:\OpenSpecimen\Apache2.2\htdocs"
        ServerAdmin biobank@yourdomain.edu
        ServerName biobank.yourdomain.edu
        SSLEngine on
        SSLCertificateFile "D:\OpenSpecimen\Apache2.2\conf\CSR\biobank_cert.crt"
        SSLCertificateKeyFile "D:\OpenSpecimen\Apache2.2\conf\CSR\biobank.key"
    	RedirectMatch ^/$ /openspecimen
        ProxyPass /openspecimen ajp://localhost:8009/openspecimen
        ProxyPassReverse /openspecimen ajp://localhost:8009/openspecimen
        SSLProtocol all -TLSv1 -SSLv2 -SSLv3
        SSLCipherSuite ALL:+HIGH:!ADH:!RC4:!MD5:!DES:!SHA:!3DES:!EXP:!SSLv2:!SSLv3:!MEDIUM:!LOW:!NULL:!aNULL
        SSLHonorCipherOrder On
        Header always set X-Frame-Options SAMEORIGIN 
        Header always set X-Content-Type-Options nosniff
    
    
    </VirtualHost>
     
    

...

  1. Note: Make sure that "SSLCertificateFile" and "SSLCertificateKeyFile" are properly located.

...


  1. In case of the new SSL module installation (3b), edit /etc/httpd/conf.d/ssl.conf file and add below lines in <VirtualHost> tag.

    Code Block
    ServerAdmin biobank@yourdomain.edu
    ServerName biobank.yourdomain.edu
    SSLCertificateFile "D:\OpenSpecimen\Apache2.2\conf\CSR\biobank_cert.crt"
    SSLCertificateKeyFile "D:\OpenSpecimen\Apache2.2\conf\CSR\biobank.key"
    RedirectMatch ^/$ /openspecimen
    ProxyPass /openspecimen ajp://localhost:8009/openspecimen
    ProxyPassReverse /openspecimen ajp://localhost:8009/openspecimen
    SSLProtocol all -TLSv1 -SSLv2 -SSLv3
    SSLCipherSuite ALL:+HIGH:!ADH:!RC4:!MD5:!DES:!SHA:!3DES:!EXP:!SSLv2:!SSLv3:!MEDIUM:!LOW:!NULL:!aNULL
    SSLHonorCipherOrder On
    Header always set X-Frame-Options SAMEORIGIN 
    Header always set X-Content-Type-Options nosniff
     
     
    Note: Remove existing entries for "SSLCertificateFile" and "SSLCertificateKeyFile" 
     Also make sure files are located at specified path.


Configuring Apache to prevent browser caching

How to

...

configure Apache to set expires header?

This header allows you an application to set a given period of time to live for web pages and other objects served from web pages. 

The idea is to inform web browsers how often they should reload objects from the server. This will save the bandwidth and server load , because clients who follow the header will reload objects less frequently. For more details on Expires Directivemodule, please refer: http://httpd.apache.org/docs/current/mod/mod_expires.html

  1. Enable expires module: 
    The expires module is not compiled by default and must be enabled in the Apache. To enable the expires module please run the below command:

    Code Block
    sudo a2enmod mod_expires


  2. Add the below directive in the <Virtual Host> section. 

    ExpiresActive On
    ExpiresDefault "access plus 3 hours"

    After updating the Virtual Host configuration will looks like below:

    Code Block
    <VirtualHost *:443>
        DocumentRoot "D:\OpenSpecimen\Apache2.2\htdocs"
        ServerAdmin biobank@yourdomain.edu
        ServerName biobank.yourdomain.edu
        
        ExpiresActive On
        ExpiresDefault "access plus 3 hours"
    
        SSLEngine on
        SSLCertificateFile "D:\OpenSpecimen\Apache2.2\conf\CSR\biobank_cert.crt"
        SSLCertificateKeyFile "D:\OpenSpecimen\Apache2.2\conf\CSR\biobank.key"
    	RedirectMatch ^/$ /openspecimen
        ProxyPass /openspecimen ajp://localhost:8009/openspecimen
        ProxyPassReverse /openspecimen ajp://localhost:8009/openspecimen
        SSLProtocol all -TLSv1 -SSLv2 -SSLv3
        SSLCipherSuite ALL:+HIGH:!ADH:!RC4:!MD5:!DES:!SHA:!3DES:!EXP:!SSLv2:!SSLv3:!MEDIUM:!LOW:!NULL:!aNULL
        SSLHonorCipherOrder On
        Header always set X-Frame-Options SAMEORIGIN 
        Header always set X-Content-Type-Options nosniff
    
    </VirtualHost>
