<title>Installation Procedure</title>
<p>When installed, the entire system, except for a small start-up
script, resides in a single directory tree. The location of this
directory tree can be chosen arbitrarily by the installer, and it
does not need to be in the user's <c>$PATH</c>. The only requirements
are that the file system where it is placed has enough free space,
and that the users who run Erlang/OTP have read access to it. In the
example below, the directory tree is assumed to be located at
<c>/usr/local/erlang</c>, which is here called the <em>top-level directory</em>.</p>
<p>It is assumed that you have the compressed tar file, the name of
which is <c><![CDATA[<PREFIX>.tar.gz]]></c>, where <c><![CDATA[<PREFIX>]]></c> is a string
denoting the particular Erlang/OTP release, e.g.
<c>otp_LXA_11930_sunos5_R9B</c>.</p>
<p>Wherever the string <c><![CDATA[<PREFIX>]]></c> is used below, it should
be replaced by the actual name prefix of the compressed tar file.</p>
<p>The tape archive file does not have one single directory in which
all other files are rooted. Therefore the tape archive file must be
extracted into an empty (newly created) directory.</p>
<list type="ordered">
<item>
<p>If the <em>top-level directory</em> does not already exist,
create it:</p>
<pre>
mkdir /usr/local/erlang</pre>
</item>
<item>
<p>Change the current directory to the <em>top level directory</em>:</p>
<pre>
cd /usr/local/erlang</pre>
</item>
<item>
<p>Create the <em>installation directory</em> with an appropriate
name. For example:</p>
<pre>
mkdir otp_r7b</pre>
</item>
<item>
<p>Change to the <em>installation directory</em>, e.g.</p>
<pre>
cd otp_r7b</pre>
</item>
<item>
<p>Assuming the compressed tar file resides in the directory
<c><![CDATA[<SOME-DIR>]]></c>,. extract the compressed tar file into the
current directory:</p>
<pre>
gunzip -c <SOME-DIR>/<PREFIX>.tar.gz | tar xfp -</pre>
</item>
<item>
<p>Read the <c>README</c> file in the installation directory for
last minute updates, before proceeding.</p>
</item>
<item>
<p>Run the <c>Install</c> script in the installation directory,
with the absolute path of the installation directory as argument,</p>
<pre>
./Install /usr/local/erlang/otp_r7b</pre>
<p>and supply answers to the prompts.</p>
<p>In most cases, there is a default answer in square brackets
(<c>[]</c>). If the default is satisfactory, just press
<c><![CDATA[<Return>]]></c>. In general you are only prompted for one thing:</p>
<list type="bulleted">
<item>
<p>"Do you want to use a minimal system startup instead of the
SASL startup?" <br></br>
In a minimal system, only the Kernel and STDLIB applications
are loaded and started. If the SASL startup is used, the SASL
application is included as well. Normally, the minimal system
is enough.</p>
</item>
</list>
</item>
<item>
<p>Make Erlang/OTP available for users, either by putting the path
<c>/usr/local/erlang/otp_r7b/bin</c> in users <c>$PATH</c>
variable, or link the executable
<c>/usr/local/erlang/otp_r7b/bin/erl</c> accordingly, e.g.:</p>
<pre>
ln -s /usr/local/erlang/otp_r7b/bin/erl /usr/local/bin/erl </pre>
