    <title>Command Explanations</title>

    <para><parameter>--libexecdir=/usr/sbin</parameter>: This switch installs
    the <command>mysqld</command> daemon 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>CPPFLAGS="-D_GNU_SOURCE"
    --with-named-thread-libs=-lpthread</parameter>: This environment variable
    and configure switch enable building on NPTL systems.</para>

    <para><parameter>--with-unix-socket-path=/var/run/mysql</parameter>:
    This switch puts the unix-domain socket into <filename

    of the bundled copy.</para>

    <para><command>make testdir=...</command>: This installs the test suite in

      <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
      unprivileged user and group (perform as the <systemitem
      class="username">root</systemitem> user):</para>

<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 be 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 setup a password for the
      administrator, so use the following command as the <systemitem
      class="username">root</systemitem> user to set one. Replace
      <replaceable>[new-password]</replaceable> with your own.</para>

<screen role="root"><userinput>mysqladmin -u root password <replaceable>[new-password]</replaceable></userinput></screen>

      <para>Configuration of the server is now finished. Shut the server
      down using the following command as the <systemitem
      class="username">root</systemitem> user:</para>

<screen role="root"><userinput>mysqladmin -p shutdown</userinput></screen>
