Prerequisites

The individual performing this installation has some Linux experience.

Root level server access.

An existing (working) Open-AudIT installation.

NOTE - This guide is for upgrading an existing Linux installation to Open-AudIT 1.0.4. If you wish to install onto a clean server, use the pre-requisites and installation guides.

Backup Your Existing Install

Backup your database. Substitute your actual username for USER (likely openaudituser), password for PASSWORD (likely openaudituserpassword), your database name (likely openaudit) for DATABASE_NAME and a suitable path and filename for BACKUP_FILE_NAME in the command below.

mysqldump -u USER -pPASSWORD DATABASE_NAME > BACKUP_FILE_NAME.sql

Backup your files by copying your existing files to a backup directory.

cp -R /usr/local/open-audit /usr/local/open-audit_backup

If the omkd daemon is installed, stop the daemon and backup the /usr/local/omk directory.

service stop omkd

cp -R /usr/local/omk /usr/local/omk_backup

Copy the Open-AudIT tarball to the server (OAE-Linux-x86_64-1.0.4.tar.gz).

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

The file will now likely be in the users home directory.

Change into the /usr/local directory.

cd /usr/local

Untar the file.

tar xvf ~/OAE-Linux-x86_64-1.0.4.tar.gz

Fix the file ownership and permissions.

chown -R root:root omk

chmod -R 775 omk

chmod -R 770 /usr/local/open-audit

chmod -R 777 /usr/local/open-audit/code_igniter/application/views/lang/

chmod 770 /usr/local/open-audit/other/audit_linux.sh

chmod 770 /usr/local/open-audit/other/audit_subnet.sh

chmod 660 /usr/local/open-audit/other/open-audit.log

Change permissions for Debian / Ubuntu

chown -R root:www-data /usr/local/open-audit

Change permissions for RedHat / CentOS

chown -R root:apache /usr/local/open-audit

Change into the omk directory

cd omk

 

Install the Daemon (if not installed)

 

Copy the daemon startup script.

 

cp /usr/local/omk/install/omkd.init.d /etc/init.d/omkd

 

Edit the start up script 

 

for Debian / Ubuntu

You need to comment out the lines (nano /etc/init.d/omkd)

. /etc/init.d/functions     # RedHat/CentOS only
 
lockfile=/var/lock/subsys/$prog     # RedHat/CentOS only

        killproc $prog           # Redhat/CentOS only

and uncomment (remove the # from the front of the line) the lines below them

# . /lib/lsb/init-functions # Debian/Ubuntu only
 
# lockfile=/var/lock/$prog           # Debian/Ubuntu only
 
        #pkill $prog              # Debian/Ubuntu only 

for RedHat / CentOS - nothing required.

 

Add the daemon

 

For Debian / Ubuntu

update-rc.d omkd start 20 2 3 4 5 . stop 20 0 1 6 . 

For RedHat / CentOS

chkconfig --add omkd 

 

 Copy the config files.

cp install/users.dat conf/

cp install/oae_reports.json conf/

cp install/opCommon.nmis conf/

Edit the config files.

nano conf/opCommon.nmis

Edit the "openauditenterprise" section and insert the actual ip address of the server (not 127.0.0.1 or localhost) in to the oae_server variable (along with http:// and don't forget the trailing /). If you have Open-AudIT installed into a subdirectory in your web root, be sure to add that to the end of the oae_server variable above. On the Opmantek virtual appliance (for example) it would be http://<SERVER_IP>/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.

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

If the omkd daemon is installed, merge the config files with those from your backed up directory. This should be done manually as new configuration items may have been added to the new file. If any items are not as per the defaults in the backed up file, copy them across.

If the omkd daemon is not installed, create the nmis user.

useradd nmis

If the omkd daemon is not installed, configure and copy the apache proxy file.

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.

nano /usr/local/omk/install/04omk-proxy.conf

Copy the apache proxy file to the correct location and restart apache.

For Debian / Ubuntu:

cp /usr/local/omk/install/04omk-proxy.conf /etc/apache2/conf.d/

service apache2 restart

 For RedHat / CentOS:

cp /usr/local/omk/install/04omk-proxy.conf /etc/httpd/conf.d/

service httpd restart

Start the daemon.

service omkd start

Edit the Open-AudIT scripts (if using a web root subdirectory)

If you have your web root in a subdirectory (as per the Opmantek virtual appliance), 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.

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

cp -Rf /usr/local/open-audit/www/* /var/www/

For RedHat / CentOS

cp -Rf /usr/local/open-audit/www/* /var/www/html/

Note - if you are upgrading the Opmantek virtual appliance, you will need to copy the files into a subdirectory.

cp -Rf /usr/local/open-audit/www/* /var/www/html/open-audit/

Fix the file permissions

For Debian / Ubuntu

chmod -R 775 /var/www/

For RedHat / CentOS

chmod -R 775 /var/www/html

For the Opmantek virtual appliance

chmod -R 775 /var/www/html/open-audit

Restore old files (if required)

Copy any attachment files from your old to the new install.

cp /usr/local/open-audit_backup/code_igniter/application/attachments/* /usr/local/open-audit/code_igniter/application/attachments/

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 http://SERVER/index.php/main/list_groups and go to Help -> About and perform 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

service apache reload

for RedHat / CentOS

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 - http://IPADDRESS/omk/oae/map

For Dashboard - http://IPADDRESS/omk/oae

For NMIS - http://IPADDRESS/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.

Enjoy Open-AudIT v1.0.4 (smile)
