Setting up https secure connection

Installing SSL

For an SSL encrypted web server you will need a few things. Depending on your install you may or may not have OpenSSL and mod_ssl, Apache's interface to OpenSSL.

yum -y install mod_ssl openssl 

Generate private key

openssl genrsa -out ca.key 2048 

Generate CSR

openssl req -new -key ca.key -out ca.csr

Generate Self Signed Key

openssl x509 -req -days 365 -in ca.csr -signkey ca.key -out ca.crt

Move the files to the correct locations

mv ca.crt /etc/pki/tls/certs
mv ca.key /etc/pki/tls/private/ca.key
mv ca.csr /etc/pki/tls/private/ca.csr

Then we need to update the Apache SSL configuration file ( /etc/httpd/conf.d/ssl.conf ). Change the paths to match where the Key file is stored. If you've used the method above it will be.

SSLCertificateFile /etc/pki/tls/certs/ca.crt  

Then set the correct path for the Certificate Key File a few lines below. If you've followed the instructions above it is:

SSLCertificateKeyFile /etc/pki/tls/private/ca.key  

Quit and save the file and then restart Apache

/etc/init.d/httpd restart

Troubleshooting:

If you cannot access GUI, try following commands:

chown -R apache:apache /var/log/httpd
service httpd restart

Allow only https

If you would like your users to be automatically redirected to secure connection (https), add the line to /etc/httpd/conf.d/mor.conf so it would look like:

<VirtualHost *:80>
 DocumentRoot /var/www/html
 <Directory /var/www/html>
  Allow from all
 </Directory>
 RailsBaseURI /billing
 <Directory /var/www/html/billing>
  Options -MultiViews
 </Directory>
 RailsEnv production
 Redirect permanent / https://www.example.com/     #Add this one. Put your hostname instead of www.example.com
</VirtualHost>

Important notes

• When you disable http access and allow https only - please make sure that you change URL in various crontabs used by mor and located in /etc/cron.d/*

ERROR: When directory structure is visible

That means incorrect configuration in /etc/httpd/conf.d/ssl.conf

Make sure your file looks like this:

#
# This is the Apache server configuration file providing SSL support.
# It contains the configuration directives to instruct the server how to
# serve pages over an https connection. For detailing information about these
# directives see <URL:http://httpd.apache.org/docs/2.2/mod/mod_ssl.html>
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.

LoadModule ssl_module modules/mod_ssl.so
 
#
# When we also provide SSL we have to listen to the
# the HTTPS port in addition.

##  SSL Global Context

#   Pass Phrase Dialog:
#   Configure the pass phrase gathering process.
#   The filtering dialog program (`builtin' is a internal
#   terminal dialog) has to provide the pass phrase on stdout.

#   Inter-Process Session Cache:
#   Configure the SSL Session Cache: First the mechanism
#   to use and second the expiring timeout (in seconds).

#   Semaphore:

#   SSL engine uses internally for inter-process synchronization.

#   Pseudo Random Number Generator (PRNG):
#   Configure one or more sources to seed the PRNG of the
#   SSL library. The seed data should be of good random quality.
#   WARNING! On some platforms /dev/random blocks if not enough entropy
#   is available. This means you then cannot use the /dev/random device
#   because it would lead to very long connection times (as long as
#   it requires to make more entropy available). But usually those
#   platforms additionally provide a /dev/urandom device which doesn't
#   block. So, if available, use this one instead. Read the mod_ssl User
#   Manual for more details.

#   Server Certificate:
# Point SSLCertificateFile at a PEM encoded certificate.  If
# the certificate is encrypted, then you will be prompted for a
# pass phrase.  Note that a kill -HUP will prompt again.  A new
# certificate can be generated using the genkey(1) command.
SSLCertificateFile /etc/pki/tls/certs/ca.crt
 
#   Server Private Key:
#   If the key is not combined with the certificate, use this

#   both in parallel (to also allow the use of DSA ciphers, etc.)

#   Server Certificate Chain:
#   Point SSLCertificateChainFile at a file containing the
#   concatenation of PEM encoded CA certificates which form the

#   the referenced file can be the same as SSLCertificateFile
#   when the CA certificates are directly appended to the server

#   Access Control:

#   on arbitrary complex boolean expressions containing server
#   variable checks and other lookup directives.  The syntax is a
#   mixture between C and Perl.  See the mod_ssl documentation
#   for more details.

#   SSL Engine Options:
#   Set various options for the SSL engine.
#   o FakeBasicAuth:
#     Translate the client X.509 into a Basic Authorisation.  This means that
#     the standard Auth/DBMAuth methods can be used for access control.  The
#     user name is the `one line' version of the client's X.509 certificate.
#     Note that no password is obtained from the user. Every entry in the user
#     file needs this password: `xxj31ZMTZzkVA'.
#   o ExportCertData:
#     This exports two additional environment variables: SSL_CLIENT_CERT and
#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
#     server (always existing) and the client (only existing when client
#     authentication is used). This can be used to import the certificates
#     into CGI scripts.
#   o StdEnvVars:
#     This exports the standard SSL/TLS related `SSL_*' environment variables.
#     Per default this exportation is switched off for performance reasons,
#     because the extraction step is an expensive operation and is usually
#     useless for serving static content. So one usually enables the
#     exportation for CGI and SSI requests only.
#   o StrictRequire:
#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
#     under a "Satisfy any" situation, i.e. when it applies access is denied
#     and no other module can change it.
#   o OptRenegotiate:
#     This enables optimized SSL connection renegotiation handling when SSL
#     directives are used in per-directory context.
#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
<Files ~ "\.(cgi|shtml|phtml|php3?)$">
    SSLOptions +StdEnvVars
</Files>
<Directory "/var/www/cgi-bin">
    SSLOptions +StdEnvVars
</Directory>
 
#   SSL Protocol Adjustments:
#   The safe and default but still SSL/TLS standard compliant shutdown
#   approach is that mod_ssl sends the close notify alert but doesn't wait for
#   the close notify alert from client. When you need a different shutdown
#   approach you can use one of the following variables:
#   o ssl-unclean-shutdown:
#     This forces an unclean shutdown when the connection is closed, i.e. no
#     SSL close notify alert is send or allowed to received.  This violates
#     the SSL/TLS standard but is needed for some brain-dead browsers. Use
#     this when you receive I/O errors because of the standard approach where
#     mod_ssl sends the close notify alert.
#   o ssl-accurate-shutdown:
#     This forces an accurate shutdown when the connection is closed, i.e. a
#     SSL close notify alert is send and mod_ssl waits for the close notify
#     alert of the client. This is 100% SSL/TLS standard compliant, but in
#     practice often causes hanging connections with brain-dead browsers. Use
#     this only for browsers where you know that their SSL implementation
#     works correctly.
#   Notice: Most problems of broken clients are also related to the HTTP
#   keep-alive facility, so you usually additionally want to disable
#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
#   "force-response-1.0" for this.
SetEnvIf User-Agent ".*MSIE.*" \
         nokeepalive ssl-unclean-shutdown \
         downgrade-1.0 force-response-1.0
 
#   Per-Server Logging:
#   The home of a custom SSL log file. Use this when you want a
#   compact non-error SSL logfile on a virtual host basis.

If you are implementing SSL into MOR please remove m2.conf file

rm -rf /etc/httpd/conf.d/m2.conf

Restart Apache after changing this file.

Check if SElinux is disabled. To disable it, check this [1]

Once SSL setups is completed, ensure that hourly actions are able to access GUI internally:

wget http://127.0.0.1/billing/callc/hourly_actions

if it does not work, adjust domain or add --no-check-certificate.

Once command works, make same adjustments on /etc/cron.d/mor_hourly_actions, mor_daily_actions and mor_monthly_actions.

!!!DO NOT TEST RUN daily AND monthly ACTIONS MANUALLY!!! just adjust cron files, save then and restart crond service.
