    <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>

    <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>There are several default configuration files available in
      <filename class="directory">/usr/share/mysql</filename> which you can
      use. When creating the file, ensure binary logs are disabled unless you
      are doing database replication.  Create <filename>/etc/my.cnf</filename>
      using the following commands as the <systemitem
      class="username">root</systemitem> user:</para>

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

      <para>You can now install a database and change the ownership to the
      unprivileged user and group (perform as the <systemitem

<screen role="root"><userinput>mysql_install_db --basedir=/usr --datadir=/srv/mysql --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>
