Prerequisites

The individual performing this installation has some Linux experience.

...

An existing (working) Open-AudIT installation.

NOTE - This guide is for upgrading an existing Linux installation to Open-AudIT 1.0.42. If you wish to install onto a clean server, use the pre-requisites prerequisites and installation guides.

NOTE - Open-AudIT 1.2 has some additional prerequisites. Please ensure you install screen, ssh-pass and samba-client via your package manager. Please also install winexe via the Suse Build Service. Details are on the prerequisites pages for RedHat/CentOS and Debian/Ubuntu.

Backup Your Existing Install

...

Copy the Open-AudIT tarball to the server (OAE-Linux-x86_64-1.0.42.tar.gz).

You may need to use SCP or FTP to get the file onto the server.

Edit the "openauditenterprise" section and insert the actual OAE_SERVER variable - By default this should be "http://127.0.0.1/open-audit/". You should not need to change this. If you do, insert the ip address of the server (not 127.0.0.1 or localhost are also fine) in to the oae_server variable (along with http:// and don't forget the trailing /). If you have Open-AudIT installed into a sub-directory in your web root, be sure to add that to the end of the oae_server variable above. For our On the Opmantek virtual appliance (for example) it would be http://<SERVER_IP>/open-audit/

OAE_LINK variable - By default this should be "/open-audit/". You should not need to change this. If you have Open-AudIT installed into a sub-directory in your web root, be sure to add that to the end of the oae_link variable above. On the Opmantek virtual appliance (for example) it would be "/open-audit/" NOTE - If your Open-AudIT Enterprise and Open-AudIT installations are on the same machine, the oae_link variable should be set to only the directory of Open-AudIT. IE - if you have an Open-AudIT install in the root of your web directory, you can set the variable to "/". On the Opmantek virtual appliance it would be set to "/open-audit/".

If you have other Opmantek software installed (NMIS, opMaps, etc) you can also edit the module_configs -> module_host variable in opCommon.nmis. Replace http://localhost with the address of the server.

If you do not have NMIS installed on the same server, set the variable omkd_require_nmis => "false" (it's in the omkd section of the config).

The email section is described in the Open-AudIT Enterprise - Configuration Guide document.

Integrate the omkd daemon 
...
Edit the file /usr/local/omk/install/04omk-proxy.conf and insert the ip address of the server into the relevant "location" sections (replacing <SERVER>). Make sure you don't use 127.0.0.1.
 Code Block
languagebash
nano /usr/local/omk/install/04omk-proxy.conf
...
with Apache
To make the Opmantek applications accessible via the web the omkd needs to be integrated with your Apache webserver, so that the Apache serving as a front-end knows how to reach the omkd-provided applications.
You need to copy the apache proxy config file to the correct location and restart apache.
Please note that it is essential that you perform the following step and replace any existing proxy config files from older Open-AudIT Enterprise installations! Release 1.2.1 corrects a security issue with the proxy configuration which could have been abused for denial-of-service attacks if Open-AudIT Enterprise was installed with unrestricted inbound access from the Internet.
For Debian / Ubuntu:
 Code Block
languagebash
cp /usr/local/omk/install/04omk-proxy.conf /etc/apache2/conf.d/
...
 Code Block
languagebash
service omkd start
Test the Daemon
You should now be able to point a web browser at http://SERVER:4082/omk/oae

Edit the Open-AudIT scripts (if using a web root subdirectory)
If you have your web root in a subdirectory, you will need to edit the "url" variable in the various script files. These files can be found in /usr/local/open-audit/other/ The files you will need to edit all begin with audit_ They include audit_linux.sh, audit_subnet.sh, audit_windows.vbs, etc, etc. The URL variable can usually be found at the top of the file.
Delete the old web files
The new web files should live in the subdirectory /open-audit/. We should remove the existing web files.
For Debian / Ubuntu (prior to 14.04)
 Code Block
languagebash
rm -rf /var/www/open-audit
 
rm -rf /var/www/device_images

rm -rf /var/www/theme-tango

rm /var/www/index.php

rm /var/www/favicon.png
For RedHat / CentOS / Ubuntu 14.04
 Code Block
languagebash
rm -rf /var/www/html/open-audit
 
rm -rf /var/www/html/device_images

rm -rf /var/www/html/theme-tango

rm /var/www/html/index.php

rm /var/www/html/favicon.png
Copy new web files
If your Open-AudIT install is into a subdirectory of your webroot, be sure to add that to the end of the destination of the cp command below.
For Debian / Ubuntu (prior to 14.04)
 Code Block
languagebash
cp -Rf /usr/local/open-audit/www/* /var/www/
For RedHat / CentOS / Ubuntu 14.04
 Code Block
languagebash
cp -Rf /usr/local/open-audit/www/* /var/www/html/
Fix the file permissions
For Debian / Ubuntu (prior to 14.04)
 Code Block
languagebash
chmod -R 775 /var/www
For RedHat / CentOS / Ubuntu 14.04
 Code Block
languagebash
chmod -R 775 /var/www/html
Restore old files (if required)
Copy any attachment files from your old to the new install.
...
If you have any Groups or Report files saved in /usr/local/open-audit_backup/code_igniter/application/controllers/(groups or reports)/ that have been custom written, you may wish to copy them to the new install. If they are already activated in the database, there should be no need.
Log in to Open-AudIT at at http://SERVER/open-audit/index.php/main/list_groups and and go to Help -> About and perform to verify that the installation status is ok; if a database upgrade is required, that page will display all relevant instructions for performing the database upgrade.
If you do not see the Open-AudIT logon page in your browser, you may need to reload the Apache config.
For Debian / Ubuntu
 Code Block
languagebash
service apache2 reload
for RedHat / CentOS
 Code Block
languagebash
service httpd reload
In the Open-AudIT web interface, go to Menu -> Admin -> Config and set the URLs for opMaps, Dashboard and NMIS. These will likely be:
For opMaps - /omk/oae/map
For Dashboard - /omk/oae
For NMIS - /cgi-nmis8/nmiscgi.pl
Check your Groups and Reports are functional. If you have some standard Groups and Reports activated, you may wish to deactivate them (Menu -> Admin -> Groups -> List Groups -> delete icon) and activate new ones (Menu -> Admin -> Groups -> Activate Group). Most Group and Report definitions have been updated. Do not deactivate Network Groups. These are created dynamically and if you deactivate them, you will either have to wait until a new computer is audited on the subnet in question (and hence the Group is recreated) or manually input a Group definition.
Ensure you copy the new audit scripts to any hosts that use them - these are usually updated.
