2.3.2 Configuring Apache
</H2>

<P>
<DL>
<DT></DT>
<DD><strong>LoadModule</strong> <a id='l2h-19' xml:id='l2h-19'></a>
<P>
If you compiled mod_python as a DSO, you will need to tell Apache to
  load the module by adding the following line in the Apache
  configuration file, usually called <span class="file">httpd.conf</span> or
  <span class="file">apache.conf</span>:

<P>
<div class="verbatim"><pre>
    LoadModule python_module libexec/mod_python.so
</pre></div>

<P>
<a id='l2h-22' xml:id='l2h-22'></a>
  The actual path to <b class="program">mod_python.so</b> may vary, but make install
  should report at the very end exactly where <b class="program">mod_python.so</b>
  was placed and how the <code>LoadModule</code> directive should appear.

<P>
</DD>
<DT></DT>
<DD><strong>Mutex Directory</strong> <a id='l2h-20' xml:id='l2h-20'></a>
<P>
The default directory for mutex lock files is <span class="file">/tmp</span>. The
  default value can be be specified at compile time using
  <em class="citetitle"><a
 href="inst-configure.html"
 title="./configure --with-mutex-dir"
 >./configure --with-mutex-dir</a></em>.

<P>
Alternatively this value can be overriden at apache startup using 
  a <em class="citetitle"><a
 href="dir-other-po.html"
 title="PythonOption"
 >PythonOption</a></em>.

<P>
<div class="verbatim"><pre>
    PythonOption mod_python.mutex_directory "/tmp"
</pre></div>

<P>
This may only be used in the server configuration context.
  It will be ignored if used in a directory, virtual host,
  htaccess or location context. The most logical place for this 
  directive in your apache configuration file is immediately
  following the <strong>LoadModule</strong> directive.

<P>
<em>New in version 3.3.0</em>

<P>
</DD>
<DT></DT>
<DD><strong>Mutex Locks</strong> <a id='l2h-21' xml:id='l2h-21'></a>
<P>
Mutexes are used in mod_python for session locking. The default
  value is 8.

<P>
On some systems the locking mechanism chosen uses valuable
  system resources. Notably on RH 8 sysv ipc is used, which 
  by default provides only 128 semaphores system-wide.
  On many other systems flock is used which may result in a relatively
  large number of open files.

<P>
The optimal number of necessary locks is not clear. 
  Increasing the maximum number of locks may increase performance
  when using session locking.  A reasonable number for 
  higher performance might be 32.

<P>
The maximum number of locks can be specified at compile time
  using <em class="citetitle"><a
 href="inst-configure.html"
 title="./configure --with-max-locks"
 >./configure --with-max-locks</a></em>.

<P>
Alternatively this value can be overriden at apache startup using 
  a <em class="citetitle"><a
 href="dir-other-po.html"
 title="PythonOption"
 >PythonOption</a></em>.

<P>
<div class="verbatim"><pre>
    PythonOption mod_python.mutex_locks 8
</pre></div>

<P>
This may only be used in the server configuration context.
  It will be ignored if used in a directory, virtual host,
  htaccess or location context. The most logical place for this 
  directive in your apache configuration file is immediately
  following the <strong>LoadModule</strong> directive.
