== How to install Aide ==
To install AIDE just issue the following command:
 
<pre><nowiki>
 yum -y install aide
 </nowiki></pre>

It installs aide but creates nothing until it is being instructed to do so.

== How to setup Aide ==
Once aide is installed, the first step is to create a new database of the current system status, ideally this must be done just after OS installation is done.  The rpm available on uWink repository has done a configuration file that is located on  `/etc/aide.conf`, and and only root can access it.
# Initialize the database
 
<pre><nowiki>
 aide -i
 </nowiki></pre>

# Set database created as "database" to be compared against
 
<pre><nowiki>
 mv /etc/aide.db.new /etc/aide.db
 </nowiki></pre>

# Change database attributes
 
<pre><nowiki>
 chattr +i /etc/aide.db
 </nowiki></pre>


== How to run Aide ==
This an abstract from the man pages.
* Checks  the database for inconsistencies. You must have an initialized database to do this. This is also the default command. Without any command aide does a check.
 
<pre><nowiki>
 --check, -C
 </nowiki></pre>

* Initialize the database. You must initialize a database and move it to the appropriate place before you can use the `--check` command.
 
<pre><nowiki>
 --init, -i
 </nowiki></pre>

* Checks the database and updates the database non-interactively.  The input and output databases must be different.
 
<pre><nowiki>
 --update, -u
 </nowiki></pre>


* Compares two databases. They must be defined in configfile with `database=<url>` and `database_new=<url>`.
 
<pre><nowiki>
 --compare
 </nowiki></pre>


* Stops after reading in the configuration file. Any errors will be reported.  If aide was compiled  with the `--with-dbhmackey` option,  a  hash  for  the  config file will be calculated. See the aide manual for more information
 
<pre><nowiki>
 --config-check, -D
 </nowiki></pre>
