This does not + apply in its full extend for the Cygwin platform. For details, + see <a href="windows.html#run">running Apache for + Windows</a>.</p> + + <h2><a id="unix" name="unix">Starting Apache on Unix</a></h2> + + <p>On Unix, the <a href="programs/httpd.html">httpd</a> program + is run as a daemon which executes continuously in the + background to handle requests. It is possible to have Apache + invoked by the Internet daemon <code>inetd</code> each time a + connection to the HTTP service is made using the <a + href="mod/core.html#servertype">ServerType</a> directive, but + this is not recommended.</p> + + <p>If the <a href="mod/core.html#port">Port</a> specified in + the configuration file is the default of 80 (or any other port + below 1024), then it is necessary to have root privileges in + order to start Apache, so that it can bind to this privileged + port. Once the server has started and completed 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 Apache's <a + href="server-wide.html#process">process creation + directives</a>.</p> + + <p>The first thing that <code>httpd</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> + + <blockquote> + <code>/usr/local/apache/bin/httpd -f + /usr/local/apache/conf/httpd.conf</code> + </blockquote> + + <p>As an alternative to invoking the <code>httpd</code> binary + directly, a shell script called <a + href="programs/apachectl.html">apachectl</a> is provided which + can be used to control the daemon process with simple commands + such as <code>apachectl start</code> and <code>apachectl + stop</code>.</p> + + <p>If all goes well during startup, the server will detach from + the terminal and the command prompt will return almost + immediately. This indicates that the server is up and running. + You can then use your browser to connect to the server and view + the test page in the <a + href="mod/core.html#documentroot">DocumentRoot</a> directory + and the local copy of the documentation linked from that + page.</p> + + <h3><a id="errors" name="errors">Errors During + Start-up</a></h3> + + <p>If Apache suffers a fatal problem during startup, it will + write a message describing the problem either to the console or + to the <a href="mod/core.html#errorlog">ErrorLog</a> before + exiting. One of the most common error messages is "<code>Unable + to bind to Port ...</code>". This message is usually caused by + either:</p> + + <ul> + <li>Trying to start the server on a privileged port when not + logged in as the root user; or</li> + + <li>Trying to start the server when there is another instance + of Apache or some other web server already bound to the same + port.</li> + </ul> + + <p>For further trouble-shooting instructions, consult the + Apache <a href="misc/FAQ.html">FAQ</a>.</p> + + <h3><a id="boot" name="boot">Starting at Boot-Time</a></h3> + + <p>If you want your server to continue running after a system + reboot, you should add a call to <code>httpd</code> or + <code>apachectl</code> to your system startup files (typically + <code>rc.local</code> or a file in an <code>rc.N</code> + directory). This will start Apache as root. Before doing this + ensure that your server is properly configured for security and + access restrictions. The <code>apachectl</code> script is + designed so that it can often be linked directly as an init + script, but be sure to check the exact requirements of your + system.</p> + + <h3><a id="info" name="info">Additional Information</a></h3> + + <p>Additional information about the command-line options of <a + href="programs/httpd.html">httpd</a> and <a + href="programs/apachectl.html">apachectl</a> as well as other + support programs included with the server is available on the + <a href="programs/">Server and Supporting Programs</a> page. + There is also documentation on all the <a + href="mod/">modules</a> included with the Apache distribution + and the <a href="mod/directives.html">directives</a> that they + provide.</p> + <hr /> + + <h3 align="CENTER">Apache HTTP Server</h3> + <a href="./"><img src="images/index.gif" alt="Index" /></a> + + </body> +</html> + + + |
