    <para><application>MySQL</application> is a widely used and fast SQL
    database server. It is a client/server implementation that consists of a
    server daemon and many different client programs and libraries.</para>

    <para>There may be a more recent release available from the
    <application>MySQL</application> home page. You can check
    <ulink url="http://dev.mysql.com/"/> and probably use the
    existing BLFS instructions. Note that versions other than the one shown
    in the download URLs have not been tested in a BLFS environment.</para>

  <sect2 role="installation">
    <title>Installation of MySQL</title>

    <para>For security reasons, running the server as an unprivileged user
    and group is strongly encouraged:</para>

<screen role="root"><userinput>groupadd -g 40 mysql &amp;&amp;
useradd -c "MySQL Server" -d /dev/null -g mysql -s /bin/false \
        -u 40 mysql</userinput></screen>

    <note><para>There are a great many options available to
    <userinput>./configure</userinput>.  Check the output of the
    <option>--help</option> option for additional customization
    options.</para></note>

    <para>Build and install <application>MySQL</application> by
    running the following commands:</para>

<screen><userinput>patch -Np1 -i ../mysql-&mysql-version;-makefile-1.patch &amp;&amp;
CFLAGS="-O3" \
CXX=gcc \
CXXFLAGS="-O3 -felide-constructors -fno-exceptions -fno-rtti" \
./configure --prefix=/usr \
            --sysconfdir=/etc \
            --libexecdir=/usr/sbin \
            --localstatedir=/srv/mysql \
            --enable-thread-safe-client \
            --enable-assembler \
            --enable-local-infile \
            --with-unix-socket-path=/var/run/mysql/mysql.sock \
            --without-debug \
            --without-readline \
            --with-plugins=innobase,myisam \
            --with-extra-charsets=all \
            --with-ssl=/usr &amp;&amp;
make</userinput></screen>

    <para>To test the results, issue: <command>make test-force 2>&amp;1 | tee
    test.log</command>.  This forces the test to run to completion and logs all
    the test output.  There will be many tests that are not run due to
    configuration options and developer considerations.  Note that if you use
    TCP Wrappers and have a restrictive <filename>/etc/hosts.deny</filename>
    file, you will need to add an appropriate entry to the
    <filename>/etc/hosts.allow</filename> file for the
    <command>mysqld</command> daemon. Otherwise many of the tests will
    fail.</para>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>make benchdir_root=/tmp \
          testroot=/tmp install &amp;&amp;
rm -rf /tmp/mysql-test /tmp/sql-bench &amp;&amp;
pushd /usr/lib &amp;&amp;
ln -v -sf mysql/libmysqlclient{,_r}.so* . &amp;&amp;
popd &amp;&amp;

pushd /usr/share/info &amp;&amp;
rm -v dir &amp;&amp;
for FILENAME in *; do
    install-info $FILENAME dir 2>/dev/null
done &amp;&amp;
popd</userinput></screen>

    <tip>
      <para>The only documentation shipped in the source tarball are
      <filename>mysql.info</filename> and man pages. You can download various
      formats of the <application>MySQL</application> Reference Manual
      from <ulink url="http://dev.mysql.com/doc/"/>.</para>

    by the developers.</para>

    <para><parameter>--libexecdir=/usr/sbin</parameter>: This switch installs
    the <command>mysqld</command> daemon and the
    <command>mysqlmanager</command> program in an appropriate location.</para>

    <para><parameter>--localstatedir=/srv/mysql</parameter>: This switch
    forces <application>MySQL</application> to use
    <filename class='directory'>/srv/mysql</filename> for database files and
    other variable data.</para>

    <para><parameter>--enable-thread-safe-client</parameter>: This
    switch compiles a thread-safe <application>MySQL</application> client
    library.</para>

    <para><parameter>--enable-assembler</parameter>: This switch allows using
    assembler versions of some string functions.</para>

    <para><parameter>--enable-local-infile</parameter>: This switch enables
    the <quote>LOAD DATA INFILE</quote> SQL statement.</para>

    <para><parameter>--with-unix-socket-path=/var/run/mysql</parameter>:
    This switch puts the unix-domain socket into the
    <filename class="directory">/var/run/mysql</filename> directory instead of
    the default <filename class="directory">/tmp</filename>.</para>

    <para><parameter>--without-readline</parameter>: This switch forces the

    of the bundled copy.</para>

    <para><parameter>--with-extra-charsets=all</parameter>: This switch enables
    international character sets within the suite.</para>

    <para><parameter>--with-plugins=innobase,myisam</parameter>: This switch enables
    two useful table types.  Check <command>./configure --help</command> for
    other table types.</para>

    <para><parameter>--with-ssl=/usr</parameter>: This switch enables encrypted
    communication between client and server using OpenSSL.</para>

    <para><command>make  benchdir_root=... install</command>: This installs the
    benchmark and test suites in a non-system location.</para>

    <para><command>ln -v -sf mysql/libmysqlclient{,_r}.so* .</command>: This
    command makes the <application>MySQL</application> shared libraries
    available to other packages at run-time.</para>

    <para><option>--with-libwrap</option>: This switch adds tcpwrappers
    support to <application>MySQL</application>.</para>

    <para><command>pushd ... popd</command>: This set of commands rebuilds the

    to do so.</para>

      <title>Configuration Information</title>

      <para>There are several default configuration files available in
      <filename class="directory">/usr/share/mysql</filename> which you can
      use. Create <filename>/etc/my.cnf</filename> using the following command
      as the <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>install -v -m644 /usr/share/mysql/my-medium.cnf /etc/my.cnf</userinput></screen>

      <para>You can now install a database and change the ownership to the

<screen role="root"><userinput>mysql_install_db --user=mysql &amp;&amp;
chgrp -v mysql /srv/mysql{,/test,/mysql}</userinput></screen>

      <para>Further configuration requires that the
      <application>MySQL</application> server is running. Start
      the server using the following commands as the <systemitem
      class="username">root</systemitem> user:</para>

<screen role="root"><userinput>install -v -m755 -o mysql -g mysql -d /var/run/mysql &amp;&amp;
mysqld_safe --user=mysql 2&gt;&amp;1 &gt;/dev/null &amp;</userinput></screen>

      <para>A default installation does not set up a password for the
      administrator, so use the following command as the <systemitem
      class="username">root</systemitem> user to set one. Replace
      <replaceable>&lt;new-password&gt;</replaceable> with your own.</para>

<screen role="root"><userinput>mysqladmin -u root password <replaceable>&lt;new-password&gt;</replaceable></userinput></screen>

      <para>Configuration of the server is now finished. Shut the server
      down using the following command as the <systemitem
