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
If the omkd daemon is not installed, install the daemon.
cp install/omkd.init.d /etc/init.d/omkd 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 sub directory in your web root, be sure to add that to the end of the oae_server variable above. For our virtual appliance it would be http://<SERVER_IP>/open-audit/
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
Test the Daemon
You should now be able to point a web browser at http://SERVER:4082/omk/oae
The default credentials are user: nmis, password: nm1888.
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 sub directory.
\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.
Restart Apache
We need to restart (or reload the config, really) Apache to enable the proxy config.
For Debian / Ubuntu
service apache reload
for RedHat / CentOS
service httpd reload
Log in to Open-AudIT at http://SERVER/index.php/main/list_groups and go to Help -> About and perform the database upgrade.
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.
