Requirements

Root level access to the Linux server.

...

A 64bit linux server running one of - RedHat 6, Centos 6, Debian 6 or 7, Ubuntu 12.04 or 14.04.

Description

As at version 1.3.1 of Open-AudIT on 16th May, 2014 (for RedHat / Centos installs only at this stage), an installation script is now shipped in the tarball. This script can perform installs, upgrades, backups, restores, uninstalls and check for install dependencies. How to perform all of the above is detailed below. The script will log it's commands to the file /tmp/install.log. If your install fails, this log will provide valuable information as to why.

...

cd /tmp
tar xf OAE-Linux-x68_64-release_1.3.1.tar.gz

Installation on a new server

To install Open-AudIT on a new server (which does not have an existing Open-AudIT installation) perform the following steps (after copying and extracting the tarball as above):

...

To access the application, go to http://<HOSTNAME>/omk/oae and you will see a logon screen.

Upgrade on an existing server

To upgrade an existing installation of Open-AudIT perform the following steps (after copying and extracting the tarball as above):

...

Your database will NOT be upgraded. You will need to log on to Open-AudIT - when you do you will be prompted to upgrade it. Go to http://<HOSTNAME>/open-audit/index.php/main/list_groups/0

Backup an existing installation

To backup an existing installation without installing or upgrading, perform the following steps (after copying and extracting the tarball as above):

...

The script will confirm you wish to take a backup of your existing files and data. If you answer 'y', a tarball will be created in /tmp named open-audit_backup-YYYY-MM-DD-HHMM.tar.gz Where YYYY is the year, MM is the month, DD is the day, HH is the hour and MM is the minute. Included in this backup will be the install script itself so a restore is as simple as an install or upgrade. See below for further details.

Restore a backup

To restore a backup taken previously by the script, perform the following steps (after copying the backup file to /tmp):

...

You will be prompted for your MySQL root user credentials. Any existing Open-AudIT files and database will be removed from the server (if they exist). The backed-up files will be restored to the server, the daemon installed and configured, the database restored and the daemon started.

Uninstalling

To uninstall Open-AudIT and delete all data  perform the following steps (after copying and extracting the tarball as above):

...

The script will offer to provide a backup of the existing files and data (as per above) and then confirm that you do wish to uninstall Open-AudIT. If you answer 'y', the files will be deleted, the daemon removed and the database and database user dropped.

Checking Dependencies

To check the dependencies are installed without actually installing perform the following steps (after copying and extracting the tarball as above):

...

The script will run, check the dependencies are installed and inform you if they are or provide information on which packages are not and offer the commands for you to install them.

Installing Dependencies

The check dependencies option above should inform you which packages are missing from your system. To install these packages follow the instructions below as appropriate for your operating system.

Installing Dependencies for RedHat 6 / Centos 6 servers

The complete list of packages required by a RedHat/Centos install are - mysql, mysql-server, httpd, php, php-cli, php-mysql, php-ldap, php-mbstring, php-mcrypt, php-process, php-snmp, php-xml, nmap, zip, curl, wget, sshpass, screen, samba-client, winexe.

...

Lastly, set the SUID for the nmap binary (so we can use the apache front end to run scripts which call nmap).

NOTE - This command will likely need to be re-run if Nmap is upgraded.

chmod u+s /usr/bin/nmap

Installing Dependencies for Debian / Ubuntu servers

The complete list of packages required by a Debian/Ubuntu install are - mysql-server, apache2, libapache2-mod-proxy-html, libapache2-mod-php5, openssh-server, php5, php5-ldap, php5-mcrypt, php5-mysql, php5-snmp, nmap, snmp, zip, wget, curl, sshpass, screen, samba-clientsmbclient, winexe.

Ensure your package manager is up to date

...

cat /etc/sysconfig/clock | grep ZONE | cut -d"\"" -f2timezone

Configure PHP (substituting <TIMEZONE> from above). Set your PHP defaults 

sed -i -e 's/memory_limit/;memory_limit/g' /etc/php5/apache2/php.ini
echo "memory_limit = 512M" >> /etc/php5/apache2/php.ini
sed -i -e 's/max_execution_time/;max_execution_time/g' /etc/php5/apache2/php.ini
echo "max_execution_time = 300" >> /etc/php5/apache2/php.ini
sed -i -e 's/max_input_time/;max_input_time/g' /etc/php5/apache2/php.ini
echo "max_input_time = 600" >> /etc/php5/apache2/php.ini
sed -i -e 's/error_reporting/;error_reporting/g' /etc/php5/apache2/php.ini
echo "error_reporting = E_ALL" >> /etc/php5/apache2/php.ini
sed -i -e 's/display_errors/;display_errors/g' /etc/php5/apache2/php.ini
echo "display_errors = On" >> /etc/php5/apache2/php.ini
sed -i -e 's/upload_max_filesize/;upload_max_filesize/g' /etc/php5/apache2/php.ini
echo "upload_max_filesize = 10M" >> /etc/php5/apache2/php.ini
sed -i -e 's/date.timezone/;date.timezone/g' /etc/php5/apache2/php.ini
echo "date.timezone = <TIMEZONE>" >> /etc/php5/apache2/php.ini

You may need to manually enable mcrypt in PHP.

php5enmod mcrypt

Set the server name for Apache, enable mod-proxy and restart
