<title>Installation of <application>Exim</application></title>
|
|
|
|
<para>Before building <application>Exim</application>, as the root user you
|
|
should create the group and user exim which will run the
|
|
<command>exim</command> daemon:</para>
|
|
|
|
<screen><userinput><command>groupadd exim &&
|
|
useradd -d /dev/null -c "Exim Daemon" -g exim -s /bin/false exim</command></userinput></screen>
|
|
|
|
<para>If you have <application>Berkeley <acronym>DB</acronym></application>
|
|
installed, apply the following patch:</para>
|
|
|
|
<screen><userinput><command>patch -Np1 -i ../exim-&exim-version;-db43-1.patch</command></userinput></screen>
|
|
|
|
<para>Install <application>Exim</application> with the following
|
|
commands:</para>
|
|

|
<screen><userinput><command>sed -e 's,^BIN_DIR.*$,BIN_DIRECTORY=/usr/sbin,' src/EDITME | \

<screen><userinput role='root'><command>make install &&

<title>Command explanations</title>
|
|
|
|
<para><command>sed -e ... > Local/Makefile</command>: Most of
|
|
<application>Exim</application>'s configuration options are compiled in using
|
|
the directives in <filename>Local/Makefile</filename> which is created from
|
|
the <filename>src/EDITME</filename> file. This command specifies the minimum
|
|
set of options. Descriptions for the options are listed below.</para>
|
|
|
|
<para><parameter>BIN_DIRECTORY=/usr/sbin</parameter>: This installs all of
|
|
<application>Exim</application>'s binaries and scripts in
|
|
<filename class='directory'>/usr/sbin</filename>.</para>
|
|
|
|
<para><parameter>CONFIGURE_FILE=/etc/exim.conf</parameter>: This installs
|
|
<application>Exim</application>'s main configuration file in
|
|
<filename class='directory'>/etc</filename>.</para>
|
|
|
|
<para><parameter>EXIM_USER=exim</parameter>: This tells
|
|
<application>Exim</application> that after the daemon no longer needs root
|
|
privileges, the process hands off the daemon to the exim user.</para>
|
|
|
|
<para><parameter>#EXIM_MONITOR</parameter>: This defers building the
|
|
<application>Exim</application> monitor program, as it requires
|
|
<application>X</application> Window System support, by commenting out the
|
|
<parameter>EXIM_MONITOR</parameter> line in the <filename>Makefile</filename>.
|
|
If you wish to build the monitor program, omit this <command>sed</command>
|
|
command and issue the following command before building the package (modify
|
|
<filename>Local/eximon.conf</filename>, if necessary):
|
|
<command>cp exim_monitor/EDITME Local/eximon.conf</command>.</para>
|
|
|
|
<para><command>ln -s exim /usr/sbin/sendmail</command>: Creates a link to
|
|
<command>sendmail</command> for applications which need it.
|
|
<application>Exim</application> will accept most
|
|
<application>Sendmail</application> command-line options.</para>

<title>Adding additional functionality</title>
|
|
|
|
<para>To utilize some or all of the dependency packages, you'll need to modify
|
|
<filename>Local/Makefile</filename> to include the appropriate directives and
|
|
parameters to link additional libraries before you build
|
|
<application>Exim</application>. <filename>Local/Makefile</filename> is
|
|
heavily commented with instructions on how to do this. Listed below is
|
|
additional information to help you link these dependency packages.</para>
