− Security Enhanced Linux Policy for the mysqld
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the mysqld processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The mysqld
processes execute with the mysqld_t SELinux type. You can
check if you have these processes running by executing the
<b>ps</b> command with the <b>−Z</b> qualifier.</p>
<p style="margin-left:11%; margin-top: 1em">For
example:</p>
<p style="margin-left:11%; margin-top: 1em"><b>ps -eZ |
grep mysqld_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The mysqld_t
SELinux type can be entered via the <b>mysqld_exec_t</b>
file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the mysqld_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/sbin/mysqld(-max|-debug)?,
/usr/sbin/ndbd, /usr/libexec/mysqld, /usr/libexec/mariadbd,

<h2>PROCESS TYPES
<a name="PROCESS TYPES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
process types (domains) for each process running on the
system</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a process using the <b>−Z</b> option to
<b>ps</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to files. SELinux mysqld
policy is very flexible allowing users to setup their mysqld
processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for mysqld:</p>
<p style="margin-left:11%; margin-top: 1em"><b>mysqld_t,
mysqld_safe_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a mysqld_t</b> can be used to make
the process type mysqld_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux
denials) messages are still generated.</p>
<h2>BOOLEANS

</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux policy
is customizable based on least access required. mysqld
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run mysqld with the
tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to

<p style="margin-left:11%; margin-top: 1em">You can see the
types associated with a port by using the following
command:</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
