= Installing SSL =
= 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.
In new MOR (starting from X14) and M2 installs, SSL with self-signed certificate is preconfigured (using external sever IP).
If you have older MOR and M2 installations, and SSL was not configured previously, you can configure self-signed certificate in MOR/M2 by running the following script. Script is tested and ready to use:


  yum -y install mod_ssl openssl
For MOR:
  svn update /usr/src/mor
/usr/src/mor/MOR_version/gui/ssl_install.sh


Generate private key
For M2:
  openssl genrsa -out ca.key 2048
  svn update /usr/src/m2
/usr/src/m2/gui/ssl_install.sh


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


Generate Self Signed Key
And restart httpd service
openssl x509 -req -days 365 -in ca.csr -signkey ca.key -out ca.crt
  service httpd restart
 
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:
Clear browser cache before testing redirect. Otherwise it might not work.
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 ==
== 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:
If you would like your users to be automatically redirected to secure connection (https), add the line to /etc/httpd/conf.d/m2.conf so it would look like:


  <VirtualHost *:80>
  <VirtualHost *:80>
Line 51: Line 32:
   Redirect permanent / https://www.example.com/    #Add this one. Put your hostname instead of www.example.com
   Redirect permanent / https://www.example.com/    #Add this one. Put your hostname instead of www.example.com
  </VirtualHost>
  </VirtualHost>
And restart httpd service
service httpd restart
Also change from http to https in cron actions:
  sed -i 's#http:#https:#'  /etc/cron.d/*actions
  service crond restart


<br><br>
<br><br>


== Important notes ==
== Configure Domain Name ==
* 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/*
 
<br><br>
If you have domain name, replace IP_ADDRESS (which will be your external IP address) with your domain name and regenerate certification files with new information with command bellow:
  openssl req -new -newkey rsa:4096 -days 365 -nodes  -x509  -keyout /etc/httpd/ssl/apache.key -out  /etc/httpd/ssl/apache.crt
Enter information as requested, in common name section please enter your domain name.
 
And restart httpd service
service httpd restart
 
 
== Cron Actions ==
If SSL redirection is enabled, 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 like this:
 
wget --no-check-certificate http://127.0.0.1/billing/callc/hourly_actions
 
For https connection use:
 
wget https://127.0.0.1/billing/callc/hourly_actions
 
Or:
 
wget --no-check-certificate https://127.0.0.1/billing/callc/hourly_actions
 
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.
 
== Connection is not private Notification ==
 
When using self-signed certificate, you will get notification that your connection is not private.
 
[[File:Privacy1.png]]
 
To fix this, press '''Advanced''' and after - '''Proceed'''. You will see this message only once from same Browser/Computer.
To avoid this message, you can buy certificates from SSL Providers.
 
== Using your own certificates ==


Configuration may vary depending on SSL provider. As always, make backup of files before editing them, so you would be able to revert in case of failure.


== ERROR: When directory structure is visible ==
If you want to use SSL Provider's certificates, you have to update self-signed configuration which should be already installed in your server.


That means incorrect configuration in /etc/httpd/conf.d/ssl.conf
Place certificate files somewhere in filesystem and update following lines in /etc/httpd/conf.d/ssl.conf with location of certificate files:


Make sure your file looks like this:
SSLCertificateFile /etc/httpd/ssl/apache.crt
SSLCertificateKeyFile /etc/httpd/ssl/apache.key
SSLCertificateChainFile /etc/pki/tls/certs/server-chain.crt

#    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

#  o StdEnvVars:
#    This exports the standard SSL/TLS related `SSL_*' environment variables.

#    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

#  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.

Installing SSL

In new MOR (starting from X14) and M2 installs, SSL with self-signed certificate is preconfigured (using external sever IP). If you have older MOR and M2 installations, and SSL was not configured previously, you can configure self-signed certificate in MOR/M2 by running the following script. Script is tested and ready to use:

For MOR: 

svn update /usr/src/mor
/usr/src/mor/MOR_version/gui/ssl_install.sh

For M2: 

svn update /usr/src/m2
/usr/src/m2/gui/ssl_install.sh


And restart httpd service 

service httpd restart

Clear browser cache before testing redirect. Otherwise it might not work.

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/m2.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>

And restart httpd service 

service httpd restart

Also change from http to https in cron actions: 

 sed -i 's#http:#https:#'  /etc/cron.d/*actions
 service crond restart




Configure Domain Name

If you have domain name, replace IP_ADDRESS (which will be your external IP address) with your domain name and regenerate certification files with new information with command bellow: 

 openssl req -new -newkey rsa:4096 -days 365 -nodes  -x509   -keyout /etc/httpd/ssl/apache.key -out  /etc/httpd/ssl/apache.crt

Enter information as requested, in common name section please enter your domain name.

And restart httpd service 

service httpd restart


Cron Actions

If SSL redirection is enabled, 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 like this: 

wget --no-check-certificate http://127.0.0.1/billing/callc/hourly_actions

For https connection use: 

wget https://127.0.0.1/billing/callc/hourly_actions

Or: 

wget --no-check-certificate https://127.0.0.1/billing/callc/hourly_actions

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.

Connection is not private Notification

When using self-signed certificate, you will get notification that your connection is not private.

Privacy1.png

To fix this, press Advanced and after - Proceed. You will see this message only once from same Browser/Computer. To avoid this message, you can buy certificates from SSL Providers.

Using your own certificates

Configuration may vary depending on SSL provider. As always, make backup of files before editing them, so you would be able to revert in case of failure.

If you want to use SSL Provider's certificates, you have to update self-signed configuration which should be already installed in your server.

Place certificate files somewhere in filesystem and update following lines in /etc/httpd/conf.d/ssl.conf with location of certificate files: 

SSLCertificateFile /etc/httpd/ssl/apache.crt
SSLCertificateKeyFile /etc/httpd/ssl/apache.key
SSLCertificateChainFile /etc/pki/tls/certs/server-chain.crt

in same file, uncomment this line and set your domain: 

ServerName www.example.com:443

save changes.

Set your domain instead of IP address in /etc/httpd/conf.d/mor_ssl.conf 

ServerName 1.2.3.4

save changes.

Restart apache to apply changes: 

service httpd restart

Check cron actions as described above.

Hardening SSL security

By default, old SSL/TLS protocols versions and ciphers are enabled which can cause security threats. To disable them, open /etc/httpd/conf.d/ssl.conf, find lines which starts with the following keywords - SSLProtocol, SSLCipherSuite. Comment them out and add following lines: 

SSLProtocol all -SSLv2 -SSLv3 -TLSv1 
SSLCipherSuite HIGH:!aNULL:!MD5:!3DES
SSLHonorCipherOrder on

Configuration with commented lines should look like this: 

#   SSL Protocol support:
# List the enable protocol levels with which clients will be able to
# connect.  Disable SSLv2 access by default:
#SSLProtocol all -SSLv2
SSLProtocol all -SSLv2 -SSLv3 -TLSv1 

#   SSL Cipher Suite:
# List the ciphers that the client is permitted to negotiate.
# See the mod_ssl documentation for a complete list.
#SSLCipherSuite DEFAULT:!EXP:!SSLv2:!DES:!IDEA:!SEED:+3DES
SSLCipherSuite HIGH:!aNULL:!MD5:!3DES
SSLHonorCipherOrder on

Restart httpd: 

service httpd restart

If after this you having problems connecting, uncoment old values, comment new ones, and restart httpd again

SSL for Resellers domain

Generate certificates for Reseller domain.

In the bottom of /etc/httpd/conf.d/ssl.conf add: 

<VirtualHost *:443>
SSLEngine on
SSLCertificateFile /path/to/resellerdomain.com.crt
SSLCertificateChainFile /path/to/resellerdomain.com.ca-bundle
SSLCertificateKeyFile /path/to/resellerdomain.com.key

ServerName resellerdomain.com

DocumentRoot /var/www/html/
</VirtualHost>

Create the file /etc/httpd/conf.d/resellerdomain_com.conf (note underscore; don't use dots in filename) with following content: 

<VirtualHost *:80>
 DocumentRoot /var/www/html
 <Directory /var/www/html>
  Allow from all
 </Directory>
 RailsBaseURI /billing
 <Directory /var/www/html/billing>
  Options -MultiViews
