Once the server has started and performed a few preliminary + activities such as opening its log files, it will launch several + <em>child</em> processes which do the work of listening for and + answering requests from clients. The main <code>httpd</code> + process continues to run as the root user, but the child processes + run as a less privileged user. This is controlled by the selected + <a href="mpm.html">Multi-Processing Module</a>.</p> + + <p>The recommended method of invoking the <code class="program"><a href="./programs/httpd.html">httpd</a></code> + executable is to use the <code class="program"><a href="./programs/apachectl.html">apachectl</a></code> control script. This + script sets certain environment variables that are necessary for + <code class="program"><a href="./programs/httpd.html">httpd</a></code> to function correctly under some operating + systems, and then invokes the <code class="program"><a href="./programs/httpd.html">httpd</a></code> binary. + <code class="program"><a href="./programs/apachectl.html">apachectl</a></code> will pass through any command line + arguments, so any <code class="program"><a href="./programs/httpd.html">httpd</a></code> options may also be used with + <code class="program"><a href="./programs/apachectl.html">apachectl</a></code>. You may also directly edit the + <code class="program"><a href="./programs/apachectl.html">apachectl</a></code> script by changing the <code>HTTPD</code> + variable near the top to specify the correct location of the + <code class="program"><a href="./programs/httpd.html">httpd</a></code> binary and any command-line arguments that you + wish to be <em>always</em> present.</p> + + <p>The first thing that <code class="program"><a href="./programs/httpd.html">httpd</a></code> does when it is + invoked is to locate and read the <a href="configuring.html">configuration file</a> + <code>httpd.conf</code>. The location of this file is set at + compile-time, but it is possible to specify its location at run + time using the <code>-f</code> command-line option as in</p> + +<div class="example"><p><code>/usr/local/apache2/bin/apachectl -f + /usr/local/apache2/conf/httpd.conf</code></p></div> + + <p>If all goes well during startup, the server will detach from + the terminal and the command prompt will return almost + immediately.

This will start Apache as + root. Before doing this ensure that your server is properly + configured for security and access restrictions.</p> + + <p>The <code class="program"><a href="./programs/apachectl.html">apachectl</a></code> script is designed to act like a + standard SysV init script; it can take the arguments + <code>start</code>, <code>restart</code>, and <code>stop</code> + and translate them into the appropriate signals to + <code class="program"><a href="./programs/httpd.html">httpd</a></code>.
