<title>Introduction to <application>My<acronym>SQL</acronym></application>
</title>

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

<title>Installation of <application>My<acronym>SQL</acronym></application>
</title>

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

<screen><userinput><command>groupadd mysql &amp;&amp;
useradd -c "MySQL Server" -d /dev/null -g mysql -s /bin/false mysql</command></userinput></screen>

<para>Build and install <application>My<acronym>SQL</acronym></application> by 
running the following commands:</para>

<screen><userinput><command>CPPFLAGS="-D_GNU_SOURCE" ./configure --prefix=/usr --sysconfdir=/etc \
    --libexecdir=/usr/sbin --localstatedir=/srv/mysql \
    --enable-thread-safe-client --enable-assembler \
    --enable-local-infile --with-named-thread-libs=-lpthread \
    --with-unix-socket-path=/var/run/mysql/mysql.sock \
    --without-debug --without-bench --without-readline &amp;&amp;
make testdir=/usr/lib/mysql/mysql-test</command></userinput></screen>

<para>Now, as the root user:</para>

<screen><userinput role='root'><command>make testdir=/usr/lib/mysql/mysql-test install &amp;&amp;
install -v -d -m755 /usr/share/mysql/Docs/Images &amp;&amp;
install -v -m644 Docs/manual{,_toc}.html \
                 Docs/manual.txt /usr/share/mysql/Docs &amp;&amp;
install -v -m644 Docs/Images/*.{jpg,gif} /usr/share/mysql/Docs/Images &amp;&amp;
cd /usr/lib &amp;&amp;
ln -v -sf mysql/libmysqlclient{,_r}.so* .</command></userinput></screen>

<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>My<acronym>SQL</acronym></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>My<acronym>SQL</acronym></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
LOAD DATA INFILE <acronym>SQL</acronym> statement.</para>

<para><parameter>CPPFLAGS="-D_GNU_SOURCE" 
--with-named-thread-libs=-lpthread</parameter>: This environment variable and 
configure switch enable building on <acronym>NPTL</acronym> systems.</para>

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

<para><parameter>--without-bench</parameter>: This switch skips building the 
benchmark suite.</para>

<para><parameter>--without-readline</parameter>: This switch forces the build 
to use the system copy of <application>readline</application> instead of the 
bundled copy.</para>

<para><command>make testdir=...</command>: This installs the test suite in 
<filename class='directory'>/usr/lib/mysql/mysql-test</filename>. 
<acronym>BLFS</acronym> is currently seeking a method to omit the installation 
of the test suite altogether.</para>

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

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

<para><option>--with-openssl</option>: This switch adds OpenSSL support
to <application>My<acronym>SQL</acronym></application>.</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 root user:</para>

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

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

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

<para>Further configuration requires that the 
<application>My<acronym>SQL</acronym></application> server be running. Start 
the server using the following commands as the root user:</para>

<screen><userinput role='root'><command>install -v -m750 -o mysql -g mysql -d /var/run/mysql &amp;&amp;
mysqld_safe --user=mysql 2&gt;&amp;1 &gt;/dev/null &amp;</command></userinput></screen>

<para>A default installation does not setup a password for the administrator, 
so use the following command as the root user to set one. Replace 
<replaceable>[new-password]</replaceable> with your own.</para>

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

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

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

<para id="mysql-init">Install the <filename>/etc/rc.d/init.d/mysql</filename> 
init script included in the <xref linkend="intro-important-bootscripts"/> 
package as the root user to start the <application>MySQL</application> server 
during system boot-up.</para>
<indexterm zone="mysql mysql-init">
<primary sortas="f-mysql">mysql</primary></indexterm>

<screen><userinput role='root'><command>make install-mysql</command></userinput></screen>
