Install SSL certificate in apache

For installation of certificate in apache use following steps:

  1. Copy all (certificate, key, CA bundle) to /etc/httpd/conf folder
  2. chmod 400 ssl.key
  3. Edit /etc/httpd/conf.d/ssl.conf and replace appropriate values. Following three values need to be updated:
    SSLCertificateFile /etc/httpd/conf/ssl.pem
    SSLCertificateKeyFile /etc/httpd/conf/ssl.key
    SSLCACertificateFile /etc/httpd/conf/ca-bundle.pem
  4. Restart apache and verify that certificate is working as expected.


Securing Apache SSL configuration

Default SSL configuration of apache is vulnerable to many attacks. We can improve apache SSL configuration as follows:

  1. Edit /etc/httpd/conf/ssl.conf and replace/insert following two values
    SSLProtocol all -SSLv2 -SSLv3
    SSLHonorCipherOrder on
    SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS"
    In case of Virtualhost 'SSLEngine On' line is also required.
  2. Check ranking of HTTPS security using https://www.ssllabs.com/ssltest/index.html
