Optimizing flag.</FONT>

</TABLE><P>It is unlikely that you will need to change any of the flags in the CFLAGS section, but at least you now know what they do. Once you have checked the src/Makefile for its contents, you can compile the server software. Issue the command:

<BR>

<BR>

<PRE>

<FONT COLOR="#000080">make linux</FONT></PRE>

<P>If you see error messages, check the configuration file carefully. The most common problem is the wrong platform (or multiple platforms) selected in the file.

<BR>

<P>Once the software is in the proper directories and compiled for your platform, it's time to configure the system. Begin with the httpd.conf-dist file. Copy it to the filename httpd.conf, which is what the server software looks for. This file handles the 
httpd server daemon. Before you edit the file, you have to decide whether you will install the Web server software to run as a daemon, or whether it will be started by inetd. If you anticipate frequent use, run the software as a daemon. For occasional use, 
either is acceptable.

<BR>

<P>There are several variables in httpd.conf that need to be checked or have values entered for them. All the variables in the configuration file follow the syntax:

<BR>

<BR>

<PRE>

<FONT COLOR="#000080">variable value</FONT></PRE>

<P>with no equals sign or special symbol between the variable name and the value assigned to it. For example, a few lines would look like this:

<BR>

<PRE>

<FONT COLOR="#000080">FancyIndexing on

HeaderName Header

ReadmeName README</FONT></PRE>

<P>Where pathnames or filenames are supplied, they are usually relative to the Web server directory, unless explicitly declared as a full pathname. You need to supply the following variables in httpd.conf:
