<p>phpMyAdmin does not apply any special security methods to the MySQL
database server. It is still the system administrator’s job to grant
permissions on the MySQL databases properly. phpMyAdmin’s <em class="guilabel">Users</em>

<ol class="arabic simple">
<li>Choose an appropriate distribution kit from the phpmyadmin.net
Downloads page. Some kits contain only the English messages, others
contain all languages. We’ll assume you chose a kit whose name
looks like <tt class="docutils literal"><span class="pre">phpMyAdmin-x.x.x</span> <span class="pre">-all-languages.tar.gz</span></tt>.</li>
<li>Untar or unzip the distribution (be sure to unzip the subdirectories):
<tt class="docutils literal"><span class="pre">tar</span> <span class="pre">-xzvf</span> <span class="pre">phpMyAdmin_x.x.x-all-languages.tar.gz</span></tt> in your
webserver’s document root. If you don’t have direct access to your
document root, put the files in a directory on your local machine,
and, after step 4, transfer the directory on your web server using,
for example, ftp.</li>
<li>Ensure that all the scripts have the appropriate owner (if PHP is
running in safe mode, having some scripts with an owner different from
the owner of other scripts will be a problem). See <a class="reference internal" href="faq.html#faq4-2"><em>4.2 What’s the preferred way of making phpMyAdmin secure against evil access?</em></a> and
<a class="reference internal" href="faq.html#faq1-26"><em>1.26 I just installed phpMyAdmin in my document root of IIS but I get the error “No input file specified” when trying to run phpMyAdmin.</em></a> for suggestions.</li>
<li>Now you must configure your installation. There are two methods that
can be used. Traditionally, users have hand-edited a copy of
<tt class="file docutils literal"><span class="pre">config.inc.php</span></tt>, but now a wizard-style setup script is provided
for those who prefer a graphical installation. Creating a
<tt class="file docutils literal"><span class="pre">config.inc.php</span></tt> is still a quick way to get started and needed for
some advanced features.</li>

<h3>Manually creating the file<a class="headerlink" href="#manually-creating-the-file" title="Permalink to this headline">¶</a></h3>
<p>To manually create the file, simply use your text editor to create the
file <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt> (you can copy <tt class="file docutils literal"><span class="pre">config.sample.inc.php</span></tt> to get
minimal configuration file) in the main (top-level) phpMyAdmin
directory (the one that contains <tt class="file docutils literal"><span class="pre">index.php</span></tt>). phpMyAdmin first
loads <tt class="file docutils literal"><span class="pre">libraries/config.default.php</span></tt> and then overrides those values
with anything found in <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt>. If the default value is
okay for a particular setting, there is no need to include it in
<tt class="file docutils literal"><span class="pre">config.inc.php</span></tt>. You’ll need a few directives to get going, a
simple configuration may look like this:</p>

<span id="setup-script"></span><span id="index-0"></span><h3>Using Setup script<a class="headerlink" href="#using-setup-script" title="Permalink to this headline">¶</a></h3>
<p>Instead of manually editing <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt>, you can use the <a class="reference external" href="setup/">Setup
Script</a>. First you must manually create a folder <tt class="docutils literal"><span class="pre">config</span></tt>
in the phpMyAdmin directory. This is a security measure. On a
Linux/Unix system you can use the following command:</p>
<div class="highlight-sh">
/usr/sbin/pma-configure
</pre></div>
</div>
<p>On other platforms, simply create the folder and ensure that your web
server has read and write access to it. <a class="reference internal" href="faq.html#faq1-26"><em>1.26 I just installed phpMyAdmin in my document root of IIS but I get the error “No input file specified” when trying to run phpMyAdmin.</em></a> can help with
this.</p>
<p>Next, open <tt class="docutils literal"><span class="pre">setup/</span></tt> in your browser. If you have an existing configuration,
use the <tt class="docutils literal"><span class="pre">Load</span></tt> button to bring its content inside the setup panel.
Note that <strong>changes are not saved to disk until explicitly choose ``Save``</strong>
from the <em>Configuration</em> area of the screen. Normally the script saves the new
<tt class="file docutils literal"><span class="pre">config.inc.php</span></tt> to the <tt class="docutils literal"><span class="pre">config/</span></tt> directory, but if the webserver does
not have the proper permissions you may see the error “Cannot load or
save configuration.” Ensure that the <tt class="docutils literal"><span class="pre">config/</span></tt> directory exists and
has the proper permissions - or use the <tt class="docutils literal"><span class="pre">Download</span></tt> link to save the
config file locally and upload it (via FTP or some similar means) to the
proper location.</p>
<p>Once the file has been saved, the permissions must be reset, again as a security
measure:</p>
<div class="highlight-sh">
/usr/sbin/pma-secure
</pre></div>
</div>
<p>Now the file is ready to be used. You can choose to review or edit the
file with your favorite editor, if you prefer to set some advanced
options which the setup script does not provide.</p>
<ol class="arabic simple">
<li>If you are using the <tt class="docutils literal"><span class="pre">auth_type</span></tt> “config”, it is suggested that you
protect the phpMyAdmin installation directory because using config
does not require a user to enter a password to access the phpMyAdmin
installation. Use of an alternate authentication method is
recommended, for example with HTTP–AUTH in a <a class="reference internal" href="glossary.html#term-htaccess"><em class="xref std std-term">.htaccess</em></a> file or switch to using
<tt class="docutils literal"><span class="pre">auth_type</span></tt> cookie or http. See the <a class="reference internal" href="faq.html#faqmultiuser"><em>ISPs, multi-user installations</em></a>
for additional information, especially <a class="reference internal" href="faq.html#faq4-4"><em>4.4 phpMyAdmin always gives “Access denied” when using HTTP authentication.</em></a>.</li>
<li>Open the <a class="reference external" href="index.php">main phpMyAdmin directory</a> in your browser.
phpMyAdmin should now display a welcome screen and your databases, or
a login dialog if using <a class="reference internal" href="glossary.html#term-http"><em class="xref std std-term">HTTP</em></a> or
cookie authentication mode.</li>
<li>You should deny access to the <tt class="docutils literal"><span class="pre">./libraries</span></tt> and <tt class="docutils literal"><span class="pre">./setup/lib</span></tt>
subfolders in your webserver configuration. For Apache you can use
supplied <a class="reference internal" href="glossary.html#term-htaccess"><em class="xref std std-term">.htaccess</em></a> file in that folder, for other webservers, you should
configure this yourself. Such configuration prevents from possible
path exposure and cross side scripting vulnerabilities that might
happen to be found in that code.</li>
<li>It is generally good idea to protect public phpMyAdmin installation
against access by robots as they usually can not do anything good
there. You can do this using <tt class="docutils literal"><span class="pre">robots.txt</span></tt> file in root of your
webserver or limit access by web server configuration, see
<a class="reference internal" href="faq.html#faq1-42"><em>1.42 How can I prevent robots from accessing phpMyAdmin?</em></a>.</li>

<p>For a whole set of new features (bookmarks, comments, <a class="reference internal" href="glossary.html#term-sql"><em class="xref std std-term">SQL</em></a>-history,
tracking mechanism, <a class="reference internal" href="glossary.html#term-pdf"><em class="xref std std-term">PDF</em></a>-generation, column contents transformation,
etc.) you need to create a set of special tables. Those tables can be located
in your own database, or in a central database for a multi-user installation
(this database would then be accessed by the controluser, so no other user
should have rights to it).</p>
<p>Please look at your <tt class="docutils literal"><span class="pre">./examples/</span></tt> directory, where you should find a
file called <em>create_tables.sql</em>. (If you are using a Windows server,
pay special attention to <a class="reference internal" href="faq.html#faq1-23"><em>1.23 I’m running MySQL on a Win32 machine. Each time I create a new table the table and column names are changed to lowercase!</em></a>).</p>
<p>If you already had this infrastructure and upgraded to MySQL 4.1.2 or
newer, please use <tt class="file docutils literal"><span class="pre">examples/upgrade_tables_mysql_4_1_2+.sql</span></tt>
and then create new tables by importing
<tt class="file docutils literal"><span class="pre">examples/create_tables.sql</span></tt>.</p>
<p>You can use your phpMyAdmin to create the tables for you. Please be
aware that you may need special (administrator) privileges to create
the database and tables, and that the script may need some tuning,
depending on the database name.</p>
<p>After having imported the <tt class="file docutils literal"><span class="pre">examples/create_tables.sql</span></tt> file, you
should specify the table names in your <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt> file. The
directives used for that can be found in the <a class="reference internal" href="config.html#config"><em>Configuration</em></a>. You will also need to
have a controluser with the proper rights to those tables (see section
<a class="reference internal" href="#authentication-modes"><em>Using authentication modes</em></a> below).</p>

<span id="upgrading"></span><h2>Upgrading from an older version<a class="headerlink" href="#upgrading-from-an-older-version" title="Permalink to this headline">¶</a></h2>
<p>Simply copy <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt> from your previous installation into
the newly unpacked one. Configuration files from old versions may
require some tweaking as some options have been changed or removed.
For compatibility with PHP 6, remove a
<tt class="docutils literal"><span class="pre">set_magic_quotes_runtime(0);</span></tt> statement that you might find near

<p>You should <strong>not</strong> copy <tt class="file docutils literal"><span class="pre">libraries/config.default.php</span></tt> over
<tt class="file docutils literal"><span class="pre">config.inc.php</span></tt> because the default configuration file is version-

<p>If you have upgraded your MySQL server from a version previous to 4.1.2 to

<span id="authentication-modes"></span><span id="index-2"></span><h2>Using authentication modes<a class="headerlink" href="#using-authentication-modes" title="Permalink to this headline">¶</a></h2>
<p><a class="reference internal" href="glossary.html#term-http"><em class="xref std std-term">HTTP</em></a> and cookie authentication modes are recommended in a <strong>multi-user
environment</strong> where you want to give users access to their own database and
don’t want them to play around with others. Nevertheless be aware that MS
Internet Explorer seems to be really buggy about cookies, at least till version
6. Even in a <strong>single-user environment</strong>, you might prefer to use <a class="reference internal" href="glossary.html#term-http"><em class="xref std std-term">HTTP</em></a>
or cookie mode so that your user/password pair are not in clear in the
configuration file.</p>
<p><a class="reference internal" href="glossary.html#term-http"><em class="xref std std-term">HTTP</em></a> and cookie authentication
modes are more secure: the MySQL login information does not need to be
set in the phpMyAdmin configuration file (except possibly for the
<span class="target" id="index-3"></span><a class="reference internal" href="config.html#cfg_Servers_controluser"><tt class="xref config config-option docutils literal"><span class="pre">$cfg['Servers'][$i]['controluser']</span></tt></a>).
However, keep in mind that the password travels in plain text, unless
you are using the HTTPS protocol. In cookie mode, the password is
stored, encrypted with the blowfish algorithm, in a temporary cookie.</p>
<p>For ‘<a class="reference internal" href="glossary.html#term-http"><em class="xref std std-term">HTTP</em></a>‘ and ‘cookie’ modes, phpMyAdmin needs a controluser that has
<strong>only</strong> the <tt class="docutils literal"><span class="pre">SELECT</span></tt> privilege on the <em>`mysql`.`user` (all columns except
`Password`)</em>, <em>`mysql`.`db` (all columns)</em>, <em>`mysql`.`host` (all columns)</em> and
<em>`mysql`.`tables_priv` (all columns except `Grantor` and `Timestamp`)</em> tables.
You must specify the details for the controluser in the <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt>
file under the <span class="target" id="index-4"></span><a class="reference internal" href="config.html#cfg_Servers_controluser"><tt class="xref config config-option docutils literal"><span class="pre">$cfg['Servers'][$i]['controluser']</span></tt></a> and

example assumes you want to use <tt class="docutils literal"><span class="pre">pma</span></tt> as the controluser and <tt class="docutils literal"><span class="pre">pmapass</span></tt> as
the controlpass, but <strong>this is only an example: use something else in your
file!</strong> Input these statements from the phpMyAdmin <a class="reference internal" href="glossary.html#term-sql"><em class="xref std std-term">SQL</em></a> Query window or

incoming HTTP requests at one’s router or firewall will suffice (both
of which are beyond the scope of this manual but easily searchable
with Google).</li>

<p>The Swekey is a low cost authentication USB key that can be used in
web applications. When Swekey authentication is activated, phpMyAdmin
requires the users’s Swekey to be plugged before entering the login
page (currently supported for cookie authentication mode only). Swekey
Authentication is disabled by default. To enable it, add the following
line to <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt>:</p>
<div class="highlight-php"><div class="highlight"><pre><span class="x">$cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';</span>
</pre></div>
</div>
<p>You then have to create the <tt class="docutils literal"><span class="pre">swekey.conf</span></tt> file that will associate
each user with their Swekey Id. It is important to place this file
outside of your web server’s document root (in the example, it is
located in <tt class="docutils literal"><span class="pre">/etc</span></tt>). A self documented sample file is provided in the
<tt class="docutils literal"><span class="pre">examples</span></tt> directory. Feel free to use it with your own users’
information. If you want to purchase a Swekey please visit
<a class="reference external" href="http://phpmyadmin.net/auth_key">http://phpmyadmin.net/auth_key</a>

<p>The phpMyAdmin team tries hardly to make the application secure, however there
are always ways to make your installation more secure:</p>
<ul class="simple">
<li>remove <tt class="docutils literal"><span class="pre">setup</span></tt> directory from phpMyAdmin, you will probably not
use it after initial setup</li>
<li>prevent access to <tt class="docutils literal"><span class="pre">libraries</span></tt> directory from browser,
as it is not needed, supplied <tt class="docutils literal"><span class="pre">.htaccess</span></tt> file does this</li>
<li>properly choose authentication method - <a class="reference internal" href="#cookie"><em>Cookie authentication mode</em></a>
is probably the best choice for shared hosting</li>
<li>in case you don’t want all MySQL users to be able to access
phpMyAdmin, you can use <span class="target" id="index-23"></span><a class="reference internal" href="config.html#cfg_Servers_AllowDeny_rules"><tt class="xref config config-option docutils literal"><span class="pre">$cfg['Servers'][$i]['AllowDeny']['rules']</span></tt></a> to limit them</li>
<li>consider hiding phpMyAdmin behind authentication proxy, so that
MySQL credentials are not all users need to login</li>
