The main configuration file is usually called 49 <code>httpd.conf</code>. The location of this file is set at 50 compile-time, but may be overridden with the <code>-f</code> 51 command line flag. In addition, other configuration files may be 52 added using the <code class="directive"><a href="/mod/core.html#include">Include</a></code> 53 directive, and wildcards can be used to include many configuration 54 files. Any directive may be placed in any of these configuration 55 files. Changes to the main configuration files are only 56 recognized by httpd when it is started or restarted.</p> 57 58 <p>The server also reads a file containing mime document types; 59 the filename is set by the <code class="directive"><a href="/mod/mod_mime.html#typesconfig">TypesConfig</a></code> directive, 60 and is <code>mime.types</code> by default.</p> 61 </div><div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 62<div class="section"> 63<h2><a name="syntax" id="syntax">Syntax of the Configuration Files</a></h2> 64 65 66 <p>httpd configuration files contain one directive per line. 67 The backslash "\" may be used as the last character on a line 68 to indicate that the directive continues onto the next line. 69 There must be no other characters or white space between the 70 backslash and the end of the line.</p> 71 72 <p>Arguments to directives are separated by whitespace. If an 73 argument contains spaces, you must enclose that argument in quotes.</p> 74 75 <p>Directives in the configuration files are case-insensitive, 76 but arguments to directives are often case sensitive. Lines 77 that begin with the hash character "#" are considered 78 comments, and are ignored. Comments may <strong>not</strong> be 79 included on a line after a configuration directive. Blank lines 80 and white space occurring before a directive are ignored, so 81 you may indent directives for clarity.</p> 82 83 <p>The values of variables defined with the <code class="directive"><a href="/mod/core.html#define">Define</a></code> of or shell environment variables can 84 be used in configuration file lines using the syntax <code>${VAR}</code>. 85 If "VAR" is the name of a valid variable, the value of that variable is 86 substituted into that spot in the configuration file line, and processing 87 continues as if that text were found directly in the configuration file. 88 Variables defined with <code class="directive"><a href="/mod/core.html#define">Define</a></code> take 89 precedence over shell environment variables. 90 If the "VAR" variable is not found, the characters <code>${VAR}</code> 91 are left unchanged, and a warning is logged. 92 Variable names may not contain colon ":" characters, to avoid clashes with 93 <code class="directive"><a href="/mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>'s syntax.</p> 94 95 <p>Only shell environment variables defined before the server is started 96 can be used in expansions. Environment variables defined in the 97 configuration file itself, for example with <code class="directive"><a href="/mod/mod_env.html#setenv">SetEnv</a></code>, take effect too late to be used for 98 expansions in the configuration file.</p> 99 100 <p>The maximum length of a line in normal configuration files, after 101 variable substitution and joining any continued lines, is approximately 102 16 MiB. In <a href="configuring.html#htaccess">.htaccess files</a>, the 103 maximum length is 8190 characters.</p> 104 105 <p>You can check your configuration files for syntax errors 106 without starting the server by using <code>apachectl 107 configtest</code> or the <code>-t</code> command line 108 option.</p> 109 110 <p>You can use <code class="module"><a href="/mod/mod_info.html">mod_info</a></code>'s <code>-DDUMP_CONFIG</code> to 111 dump the configuration with all included files and environment 112 variables resolved and all comments and non-matching 113 <code class="directive"><a href="/mod/core.html#ifdefine"><IfDefine></a></code> and 114 <code class="directive"><a href="/mod/core.html#ifmodule"><IfModule></a></code> sections 115 removed.

This implies that only the most 125 basic functionality is included in the core server. Extended 126 features are available through <a href="mod/">modules</a> which can be loaded 127 into httpd. By default, a <a href="mod/module-dict.html#Status">base</a> set of modules is 128 included in the server at compile-time. If the server is 129 compiled to use <a href="dso.html">dynamically loaded</a> 130 modules, then modules can be compiled separately and added at 131 any time using the <code class="directive"><a href="/mod/mod_so.html#loadmodule">LoadModule</a></code> 132 directive. 133 Otherwise, httpd must be recompiled to add or remove modules. 134 Configuration directives may be included conditional on a 135 presence of a particular module by enclosing them in an <code class="directive"><a href="/mod/core.html#ifmodule"><IfModule></a></code> block. However, 136 <code class="directive"><IfModule></code> blocks are not 137 required, and in some cases may mask the fact that you're missing an 138 important module.</p> 139 140 <p>To see which modules are currently compiled into the server, 141 you can use the <code>-l</code> command line option. You can also 142 see what modules are loaded dynamically using the <code>-M</code> 143 command line option.</p> 144 </div><div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 145<div class="section"> 146<h2><a name="scope" id="scope">Scope of Directives</a></h2> 147 148 149 <table class="related"><tr><th>Related Modules</th><th>Related Directives</th></tr><tr><td /><td><ul><li><code class="directive"><a href="/mod/core.html#directory"><Directory></a></code></li><li><code class="directive"><a href="/mod/core.html#directorymatch"><DirectoryMatch></a></code></li><li><code class="directive"><a href="/mod/core.html#files"><Files></a></code></li><li><code class="directive"><a href="/mod/core.html#filesmatch"><FilesMatch></a></code></li><li><code class="directive"><a href="/mod/core.html#location"><Location></a></code></li><li><code class="directive"><a href="/mod/core.html#locationmatch"><LocationMatch></a></code></li><li><code class="directive"><a href="/mod/core.html#virtualhost"><VirtualHost></a></code></li></ul></td></tr></table> 150 151 <p>Directives placed in the main configuration files apply to 152 the entire server. If you wish to change the configuration for 153 only a part of the server, you can scope your directives by 154 placing them in <code class="directive"><a href="/mod/core.html#directory"><Directory></a></code>, <code class="directive"><a href="/mod/core.html#directorymatch"><DirectoryMatch></a></code>, <code class="directive"><a href="/mod/core.html#files"><Files></a></code>, <code class="directive"><a href="/mod/core.html#filesmatch"><FilesMatch></a></code>, <code class="directive"><a href="/mod/core.html#location"><Location></a></code>, and <code class="directive"><a href="/mod/core.html#locationmatch"><LocationMatch></a></code> 155 sections. These sections limit the application of the 156 directives which they enclose to particular filesystem 157 locations or URLs. They can also be nested, allowing for very 158 fine grained configuration.</p> 159 160 <p>httpd has the capability to serve many different websites 161 simultaneously. This is called <a href="vhosts/">Virtual 162 Hosting</a>. Directives can also be scoped by placing them 163 inside <code class="directive"><a href="/mod/core.html#virtualhost"><VirtualHost></a></code> 164 sections, so that they will only apply to requests for a 165 particular website.</p> 166 167 <p>Although most directives can be placed in any of these 168 sections, some directives do not make sense in some contexts. 169 For example, directives controlling process creation can only 170 be placed in the main server context. To find which directives 171 can be placed in which sections, check the <a href="mod/directive-dict.html#Context">Context</a> of the 172 directive. For further information, we provide details on <a href="sections.html">How Directory, Location and Files sections 173 work</a>.</p> 174 </div><div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 175<div class="section"> 176<h2><a name="htaccess" id="htaccess">.htaccess Files</a></h2> 177 178 179 <table class="related"><tr><th>Related Modules</th><th>Related Directives</th></tr><tr><td /><td><ul><li><code class="directive"><a href="/mod/core.html#accessfilename">AccessFileName</a></code></li><li><code class="directive"><a href="/mod/core.html#allowoverride">AllowOverride</a></code></li></ul></td></tr></table> 180 181 <p>httpd allows for decentralized management of configuration 182 via special files placed inside the web tree. The special files 183 are usually called <code>.htaccess</code>, but any name can be 184 specified in the <code class="directive"><a href="/mod/core.html#accessfilename">AccessFileName</a></code> 185 directive. Directives placed in <code>.htaccess</code> files 186 apply to the directory where you place the file, and all 187 sub-directories. The <code>.htaccess</code> files follow the 188 same syntax as the main configuration files. Since 189 <code>.htaccess</code> files are read on every request, changes 190 made in these files take immediate effect.</p> 191 192 <p>To find which directives can be placed in 193 <code>.htaccess</code> files, check the <a href="mod/directive-dict.html#Context">Context</a> of the 194 directive. The server administrator further controls what 195 directives may be placed in <code>.htaccess</code> files by 196 configuring the <code class="directive"><a href="/mod/core.html#allowoverride">AllowOverride</a></code> 197 directive in the main configuration files.</p> 198 199 <p>For more information on <code>.htaccess</code> files, see 200 the <a href="howto/htaccess.html">.htaccess tutorial</a>.</p> 201 </div></div> 202<div class="bottomlang"> 203<p><span>Available Languages: </span><a href="/de/configuring.html" hreflang="de" rel="alternate" title="Deutsch"> de </a> | 204<a href="/en/configuring.html" title="English"> en </a> | 205<a href="/fr/configuring.html" hreflang="fr" rel="alternate" title="Fran�ais"> fr </a> | 206<a href="/ja/configuring.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> | 207<a href="/ko/configuring.html" hreflang="ko" rel="alternate" title="Korean"> ko </a> | 208<a href="/tr/configuring.html" hreflang="tr" rel="alternate" title="T�rk�e"> tr </a></p> 209</div><div class="top"><a href="#page-header"><img src="/images/up.gif" alt="top" /></a></div><div class="section"><h2><a id="comments_section" name="comments_section">Comments</a></h2><div class="warning"><strong>Notice:</strong><br />This is not a Q&A section.
