The main configuration file is usually called 53 <code>httpd.conf</code>. The location of this file is set at 54 compile-time, but may be overridden with the <code>-f</code> 55 command line flag. In addition, other configuration files may be 56 added using the <code class="directive"><a href="./mod/core.html#include">Include</a></code> 57 directive, and wildcards can be used to include many configuration 58 files. Any directive may be placed in any of these configuration 59 files. Changes to the main configuration files are only 60 recognized by Apache when it is started or restarted.</p> 61 62 <p>The server also reads a file containing mime document types; 63 the filename is set by the <code class="directive"><a href="./mod/mod_mime.html#typesconfig">TypesConfig</a></code> directive, 64 and is <code>mime.types</code> by default.</p> 65 </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div> 66 <div class="section"> 67 <h2><a name="syntax" id="syntax">Syntax of the Configuration Files</a></h2> 68 69 70 <p>Apache configuration files contain one directive per line. 71 The backslash "\" may be used as the last character on a line 72 to indicate that the directive continues onto the next line. 73 There must be no other characters or white space between the 74 backslash and the end of the line.</p> 75 76 <p>Directives in the configuration files are case-insensitive, 77 but arguments to directives are often case sensitive. Lines 78 that begin with the hash character "#" are considered 79 comments, and are ignored. Comments may <strong>not</strong> be 80 included on the same line as a configuration directive. 81 White space occurring before a directive is ignored, so 82 you may indent directives for clarity. Blank lines are also ignored.</p> 83 84 <p>The values of shell environment variables can be used in 85 configuration file lines using the syntax <code>${ENVVAR}</code>. 86 If "ENVVAR" is the name of a valid environment variable, the value 87 of that variable is substituted into that spot in the 88 configuration file line, and processing continues as if that text 89 were found directly in the configuration file. (If the ENVVAR 90 variable is not found, the characters "${ENVVAR}" are left 91 unchanged for use by later stages in the config file 92 processing.)</p> 93 94 <p>The maximum length of a line in the configuration file, after 95 environment-variable substitution, joining any continued lines and 96 removing leading and trailing white space, is 8192 characters.</p> 97 98 <p>You can check your configuration files for syntax errors 99 without starting the server by using <code>apachectl 100 configtest</code> or the <code>-t</code> command line 101 option.</p> 102 </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div> 103 <div class="section"> 104 <h2><a name="modules" id="modules">Modules</a></h2> 105 106 107 <table class="related"><tr><th>Related Modules</th><th>Related Directives</th></tr><tr><td><ul><li><code class="module"><a href="./mod/mod_so.html">mod_so</a></code></li></ul></td><td><ul><li><code class="directive"><a href="./mod/core.html#ifmodule"><IfModule></a></code></li><li><code class="directive"><a href="./mod/mod_so.html#loadmodule">LoadModule</a></code></li></ul></td></tr></table> 108 109 <p>Apache is a modular server. This implies that only the most 110 basic functionality is included in the core server. Extended 111 features are available through <a href="mod/">modules</a> which can be loaded 112 into Apache. By default, a <a href="mod/module-dict.html#Status">base</a> set of modules is 113 included in the server at compile-time. If the server is 114 compiled to use <a href="dso.html">dynamically loaded</a> 115 modules, then modules can be compiled separately and added at 116 any time using the <code class="directive"><a href="./mod/mod_so.html#loadmodule">LoadModule</a></code> 117 directive. 118 Otherwise, Apache must be recompiled to add or remove modules. 119 Configuration directives may be included conditional on a 120 presence of a particular module by enclosing them in an <code class="directive"><a href="./mod/core.html#ifmodule"><IfModule></a></code> block.</p> 121 122 <p>To see which modules are currently compiled into the server, 123 you can use the <code>-l</code> command line option.</p> 124 </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div> 125 <div class="section"> 126 <h2><a name="scope" id="scope">Scope of Directives</a></h2> 127 128 129 <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> 130 131 <p>Directives placed in the main configuration files apply to 132 the entire server. If you wish to change the configuration for 133 only a part of the server, you can scope your directives by 134 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> 135 sections. These sections limit the application of the 136 directives which they enclose to particular filesystem 137 locations or URLs. They can also be nested, allowing for very 138 fine grained configuration.</p> 139 140 <p>Apache has the capability to serve many different websites 141 simultaneously. This is called <a href="vhosts/">Virtual 142 Hosting</a>. Directives can also be scoped by placing them 143 inside <code class="directive"><a href="./mod/core.html#virtualhost"><VirtualHost></a></code> 144 sections, so that they will only apply to requests for a 145 particular website.</p> 146 147 <p>Although most directives can be placed in any of these 148 sections, some directives do not make sense in some contexts. 149 For example, directives controlling process creation can only 150 be placed in the main server context. To find which directives 151 can be placed in which sections, check the <a href="mod/directive-dict.html#Context">Context</a> of the 152 directive. For further information, we provide details on <a href="sections.html">How Directory, Location and Files sections 153 work</a>.</p> 154 </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div> 155 <div class="section"> 156 <h2><a name="htaccess" id="htaccess">.htaccess Files</a></h2> 157 158 159 <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> 160 161 <p>Apache allows for decentralized management of configuration 162 via special files placed inside the web tree. The special files 163 are usually called <code>.htaccess</code>, but any name can be 164 specified in the <code class="directive"><a href="./mod/core.html#accessfilename">AccessFileName</a></code> 165 directive. Directives placed in <code>.htaccess</code> files 166 apply to the directory where you place the file, and all 167 sub-directories. The <code>.htaccess</code> files follow the 168 same syntax as the main configuration files. Since 169 <code>.htaccess</code> files are read on every request, changes 170 made in these files take immediate effect.</p> 171 172 <p>To find which directives can be placed in 173 <code>.htaccess</code> files, check the <a href="mod/directive-dict.html#Context">Context</a> of the 174 directive. The server administrator further controls what 175 directives may be placed in <code>.htaccess</code> files by 176 configuring the <code class="directive"><a href="./mod/core.html#allowoverride">AllowOverride</a></code> 177 directive in the main configuration files.</p> 178 179 <p>For more information on <code>.htaccess</code> files, see 180 the <a href="howto/htaccess.html">.htaccess tutorial</a>.</p> 181 </div></div> 182 <div class="bottomlang"> 183 <p><span>Available Languages: </span><a href="./de/configuring.html" hreflang="de" rel="alternate" title="Deutsch"> de </a> | 184 <a href="./en/configuring.html" title="English"> en </a> | 185 <a href="./fr/configuring.html" hreflang="fr" rel="alternate" title="Français"> fr </a> | 186 <a href="./ja/configuring.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> | 187 <a href="./ko/configuring.html" hreflang="ko" rel="alternate" title="Korean"> ko </a> | 188 <a href="./tr/configuring.html" hreflang="tr" rel="alternate" title="Türkçe"> tr </a></p> 189 </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.
