<para>
This chapter includes databases that range from single-user
read/write to industrial database servers with transaction support.
Generally, you will be sent here to satisfy dependencies to other
applications although building a SQL server on a base LFS system is
entirely possible.

<para>
To avoid situations like this (i.e., your database server
software refuses to start), read the following discussion of the best way to
upgrade a DBMS (Database Management System).
</para>
<para>
The root cause of the error shown above was an upgrade
of the server software to a newer major version which left the
data files untouched. In this case, the administrator was able to recover
the DBMS without any loss of data.
</para>
<para>
Even if you are doing an initial DBMS install, read through this
section. It provides information about implementing backup
and restore procedures (or at least a strategy for creating
them) which will satisfy your needs and guarantee the safety
of your data.
</para>
<sect2>
<title>Upgrade Database Server Packages</title>
<para>
Database systems work on files which hold the database metadata and the
data itself. The internal structure of these files is optimized for use
by the server software. When such server software is upgraded,
the new software may utilize a different file format than
had previously been used. Sometimes the new software can
work with the old format as well as the new one&mdash;but without the
performance improvements the new format provides.
Other times, the new server software will
reformat the data files automatically after the upgrade.
</para>
<para>
Unfortunately, the most likely case is that the new server software
complains about out of date file formats and exits. When this happens,
and you have overwritten the old server software, you may end up
with a broken system and lost data.
</para>
<para>
Changes in data file formats usually happen at major version changes, but
they can also occur at other times. Before upgrading any DBMS
software, check the documentation to see if this upgrade makes changes which
require reformatting the database.
</para>
<para>
Of course, if you have databases with content that is not easily
rebuilt, it is always a good idea to create backups of the database from
time to time. Before upgrading the server software, you should run
another backup.
</para>
<sect3>
<title>Upgrade by Backup and Restore</title>
<note>
<para>
A backup is useless if there is no verified process
to restore the data from this backup. When running a
database server, you should not only create backups; you
should also verify that the restore process
really works. The time to test the restore procedure
is <emphasis>before</emphasis> you urgently need
to recover lost data.
</para>
</note>
<para>
Most database server software provides some basic
tools to create backups of your data. Usually the backups created with
those tools can be read by newer versions of the software (via a
restore tool). Using older restore tools with newer backup data is
a bad idea; you should <emphasis>never</emphasis> blindly assume that
it will work. It might, but usually it doesn't.
</para>
<para>
The easiest way to upgrade your database files is to
</para>
<itemizedlist>
<listitem>
<para>Create a full database backup using the old tools.</para>
<para>This step creates an offline copy of the database files&mdash;for
long term archiving, for disaster recovery, or as
preparation for an upgrade. This offline backup consists of either (1) a full
one-to-one copy of the current database files, or (2) a full backup of the
database files from a certain point in time, plus all the journal data (that is
Oracle&reg; terminology, it is called "Continuous Archiving" or
"write ahead log (WAL)" in Postgresql) describing the
changes made after that point in time. This second form takes less time to create
(if the DB software provides this type of journaling) because you only have
to save the data that have changed since the last full backup was created.</para>
<para>When upgrading database server software, a full backup
(which can be used for subsequent incremental backups) should be
created; but if there is a lot of data, an incremental backup will
suffice. The best strategy for you depends on
the amount of data stored in your database (is it a few hundred table
rows, or is it hundreds of terabytes?). A full backup in the latter case
can't be done quickly. To
fully protect your data, create a backup of the old
programs (and/or their sources) and save it, along with the data
files, to be certain there is a fallback solution if
the new software cannot read the old data.</para>
</listitem>
<listitem>
<para>Upgrade the server software</para>
<para>In this step, instructions to build the database server
software are executed just as they are shown in subsequent sections
talking about the DBMs like MariaDB or Postgresql. That is, build
the software as usual using BLFS instructions.</para>
</listitem>
<listitem>
<para>Restore the database by using the new tools.</para>
<para>To restore the data, the tools of the newly installed server
software should be used. During the restoration process, the new
tools will create and/or upgrade the data files in the format the
new software requires. It is assumed that newer software is capable of
reading old data.</para>
</listitem>
</itemizedlist>
<para>
Since you already have a backup procedure in place (and you
have tested your restore procedure, right?), this might
be the easiest way to upgrade as you can use your well known
processes to upgrade just as you always do&mdash;at least in terms
of the backup and restore.
</para>
</sect3>
<sect3>
<title>Upgrade the Database Files by Using System Tools</title>
<para>
Some database systems (for instance Postgresql) provide
a tool which can reformat (upgrade) the existing database
files to the new format.
If you need to restore from a backup (for example, running
the upgrade tool failed) you will have to reinstall the old software
to recover your data.
</para>
<para>
Even though the reformatting tools might work as advertised,
you should create a full backup before running them. A failure
could cause serious damage to the database.

<sect3>
<title>Sqlite</title>
<!-- might add some advanced notes for the DBMS here -->
<para>Do not underestimate <application>Sqlite</application>. It is a
feature-rich DBMS. The main difference from the two big players above is
that Sqlite does not provide access via a network API. Sqlite databases
are always stored on the machine running the program which
uses the database. The manipulation of data content is done via API calls
to library functions directly within the program.</para>
<para>In the upstream documentation you may find the following
useful:</para>

<ulink url="https://www.sqlite.org/cli.html"/>
</para>
<para>Documentation of backup API calls:
<ulink url="https://www.sqlite.org/backup.html"/>
</para>
<para>Unfortunately, there is no dedicated chapter in the
upstream documentation talking about backup/restore, but
there are several articles about it on the
Internet. Here is an example.</para>

<title>LMDB</title>
<!-- might add some advanced notes for the DBMS here -->
<para>Like <application>Sqlite</application>, this
software acts on local database files; there is no

<para>The relevant resources to back up/restore a LMDB database
are the man pages for <filename>mdb_dump</filename> and its

assumes that the <filename class="directory">/var/mail</filename>
directory is world writable, but has the sticky bit set. If you want

<para>
A default (nothing but comments) <filename>/etc/aliases</filename>
file is installed during the package installation if this file did not
exist on your system. Create the necessary aliases and start the
<application>Exim</application> daemon using the following commands:
</para>
<screen role="root"><userinput>cat &gt;&gt; /etc/aliases &lt;&lt; "EOF"
<literal>postmaster: root

EOF
/usr/sbin/exim -bd -q15m</userinput></screen>
<note>
<para>
To protect an existing <filename>/etc/aliases</filename> file,
the command above appends these aliases to it. This file should be
checked and duplicate aliases removed, if present.
</para>
</note>
<para>
The <command>/usr/sbin/exim -bd -q15m</command> command starts

<title>Configuring the Build</title>
<para>
The README files are formatted to be read with a pager like

If you want to use a text editor, make them legible with the
following sed:
</para>
<screen><userinput>sed -i 's/.\x08//g' README_FILES/*</userinput></screen>
<para>
The <application>Postfix</application> source tree does not contain a
<filename>configure</filename> script, rather the makefile in the
top-level directory contains a <option>makefiles</option> target that
regenerates all the other makefiles in the build tree. If you wish to
use additional software such as a database back-end for virtual users,
or TLS/SSL authentication, you will need to regenerate the makefiles
using one or more of the appropriate <envar>CCARGS</envar> and
<envar>AUXLIBS</envar> settings listed below.
</para>
<note>
<para>
For all variants of the CCARGS you should ensure that -DNO_NIS is
specified so that the build does not attempt to access an rpcsvc
header which do not exist in BLFS. If &berkeley-db; is
not installed, -DNO_DB needs to be specified as well.
</para>
</note>
<para>
For more details read the readme files.
</para>
<para>
Initialize the <envar>CCARGS</envar> and <envar>AUXLIBS</envar>
according to the note above:
</para>

<para>
Next, the <envar>CCARGS</envar> and the <envar>AUXLIBS</envar>
variables are filled with settings depending on the actual
system configuration. If an optional package is installed but

Create (or append to an existing) <filename>/etc/aliases</filename>
with the following command. Change
<replaceable>&lt;LOGIN&gt;</replaceable> to your non-root login
identity so mail addressed to
<systemitem class="username">root</systemitem> can be forwarded to you.
As the <systemitem class="username">root</systemitem> user:

<screen role="root"><userinput>cat &gt;&gt; /etc/aliases &lt;&lt; "EOF"

root: <replaceable>&lt;LOGIN&gt;</replaceable>
# End /etc/aliases</literal>

<para>
To protect an existing <filename>/etc/aliases</filename> file,
the above command appends these aliases to it if it exists. This file
should be checked and duplicate aliases removed, if present.
</para>
<para>
The BLFS editors recommend to use LMDB instead of Berkeley DB for
Postfix tables. Add three lines into
<filename>/etc/postfix/main.cf</filename> to make
<command>postmap</command> encode the lookup tables in the LMDB
format by default and to change the default hash setting of the
alias tables:
</para>
<screen role="root"><userinput>echo 'default_database_type = lmdb' &gt;&gt; /etc/postfix/main.cf &amp;&amp;
echo 'alias_database = lmdb:/etc/aliases' &gt;&gt; /etc/postfix/main.cf &amp;&amp;
echo 'alias_maps = lmdb:/etc/aliases' &gt;&gt; /etc/postfix/main.cf</userinput></screen>
<para>
To protect your server against the recent SMTP smuggling attacks,
additional steps are required. Add two lines into
<filename>/etc/postfix/main.cf</filename> to disconnect remote SMTP
clients that send bare newlines in the DATA section, while also
allowing clients on your network with non-standard SMTP implementations
to still send mail:
</para>
<screen role="root"><userinput>echo 'smtpd_forbid_bare_newline = normalize' &gt;&gt; /etc/postfix/main.cf &amp;&amp;
echo 'smtpd_forbid_bare_newline_exclusions = $mynetworks' &gt;&gt; /etc/postfix/main.cf</userinput></screen>
<para>
Note that if you are following an online tutorial to configure
Postfix, the tutorial may refer to a lookup table with
<literal>hash:/path/to/lookup_table</literal>. You should replace
<literal>hash</literal> with <literal>lmdb</literal> in order to use
a lookup table encoded in the LMDB format.
</para>
<note>
<para>
The <filename>/etc/postfix/main.cf</filename> and
<filename>/etc/postfix/master.cf</filename> files must be personalized
for your system. The <filename>main.cf</filename> file needs your
fully qualified hostname. You will find that
<filename>main.cf</filename> is self documenting, so load it into your
editor to make the changes you need for your situation.

<para>
<command>sed -e '/encoding.h/a ...</command>; Fix building against

<para>
<parameter>--enable-authnz-fcgi</parameter>: Build FastCGI
authorizer-based authentication and authorization (mod_authnz_fcgi.so
fast CGI module).
</para>
<para>
<parameter>--enable-mods-shared="all cgi"</parameter>: The modules should be
compiled and used as Dynamic Shared Objects (DSOs) so they can be included
and excluded from the server using the run-time configuration directives.
</para>
<para>
<parameter>--enable-mpms-shared=all</parameter>: This switch ensures that
all MPM (Multi Processing Modules) are built as Dynamic Shared Objects
(DSOs), so the user can choose which one to use at runtime.
</para>
<para>
<parameter>--enable-suexec</parameter>: This switch enables building of the
<application>Apache</application> suEXEC module which can be used to allow
users to run CGI and SSI scripts under user IDs different from the user ID
of the calling web server.
</para>
<para>
<parameter>--with-suexec-*</parameter>: These switches control suEXEC module
behavior, such as default document root, minimal UID that can be used to
run the script under the suEXEC. Please note that with minimal UID 100, you
can't run CGI or SSI scripts under suEXEC as the
<systemitem class="username">apache</systemitem> user.
</para>
<para>
<command>... /usr/lib/httpd/suexec</command>: These commands put
<command>suexec</command> wrapper into proper location, since it
is not meant to be run directly. They also adjust proper
permissions of the binary, making it setgid
<systemitem class="username">apache</systemitem>.
</para>
<para>
<command>chown -R apache:apache /srv/www</command>: By default, the
installation process installs files (documentation, error messages,
default icons, etc.) with the ownership of the user that extracted the
files from the tar file. If you want to change the ownership to another
user, you should do so at this point. The only requirement is that the
document directories need to be accessible by the <command>httpd</command>
process with (r-x) permissions and files need to be readable (r--) by the
<systemitem class="username">apache</systemitem> user.

<title>Administrator Reference Manual (ARM)</title>
<para>
The ARM documentation (do not confuse with the processor architecture)
is included in the source package. The documentation is in .rst
format which means that it can be converted in human readable formats
if <xref linkend="sphinx"/> is installed.
</para>
<para>
When <application>BIND</application> is set up, especially if it is going
to be operating in a real live scenario, it is <emphasis>highly</emphasis>
recommended to consult the ARM documentation. ISC provides an
updated set of excellent documentation along with every release
so it can be easily viewed and/or downloaded &ndash; so there is
no excuse to not read the docs. The formats ISC provides are PDF,
epub and html at <ulink url="https://downloads.isc.org/isc/bind9/&bind-version;/doc/arm/"/>.

<title>Configuring ISC Kea DHCP Server</title>
<para>
The support of IPv4, IPv6 and DDNS has been split into
separate servers which runs independently from each other. Each
of them has its own configuration file.<phrase revision="sysv">
Additional configuration files come from the keactrl agent which
is used to control the servers in an easy way.</phrase>
</para>
<para>
Consult the <ulink
url="https://kea.readthedocs.io/en/kea-&kea-arm-vers;/">
Kea Administrator Reference Manual</ulink>
for detailed information about the configuration of
<application>ISC Kea</application> as it is a quite capable system.
The configuration shown below is a bare minimum to get a DHCP server
running but it already includes configuration for DDNS (Dynamic DNS).
That setup might be working for small networks with a few clients and
low traffic. For greater installations with thousands of clients,
<application>ISC Kea</application> can be configured to use databases
(mariadb or postgresql) to store the leases and build a cluster with
multiple nodes. It can be integrated to
<ulink url="https://www.isc.org/categories/stork/">ISC Stork</ulink>
which is a management dashboard to <application>ISC Kea</application>.

By default, proftpd will require that users logging in have valid
shells. The RequireValidShell directive turns off this requirement.
This is only recommended if you are setting up your FTP server
exclusively for anonymous downloads.

Having slapd configuration files and ldap databases in /var/lib/openldap
readable by anyone is a SECURITY ISSUE, especially since a file stores the
admin password in PLAIN TEXT. That's why mode 640 and root:ldap ownership
were used. The owner is root, so only root can modify the file, and group is
ldap, so that the group which owns slapd daemon could read but not modify
the file in case of a security breach.

<para>
Configuring the <command>slapd</command> servers can be complex.
Securing the LDAP directory, especially if you are storing non-public
data such as password databases, can also be a challenging task. In
order to set up <application>OpenLDAP</application>, you'll need to
modify either the <filename>/etc/openldap/slapd.conf</filename>
file (old method), or the <filename>/etc/openldap/slapd.ldif</filename>
file and then use <command>ldapadd</command> to create the LDAP
configuration database in
<filename class="directory">/etc/openldap/slapd.d</filename>
(recommended by the OpenLDAP documentation).
</para>
