httpd.conf httpd AuthorOrtonJoejorton@redhat.com httpd.conf 5 httpd.conf Configuration files for httpd /etc/httpd/conf/httpd.conf, /etc/httpd/conf.modules.d, /etc/httpd/conf.d Description The main configuration file for the httpd daemon is /etc/httpd/conf/httpd.conf. The syntax of this file is described at , and the full set of available directives is listed at . Configuration structure The main configuration file (httpd.conf) sets up various defaults and includes configuration files from two directories - /etc/httpd/conf.modules.d and /etc/httpd/conf.d. Packages containing loadable modules (like ) place files in the conf.modules.d directory with the appropriate directive so that module is loaded by default. Some notable configured defaults are: The default document root from which content is served. The daemon listens on TCP port 80. Error messages are logged to @LOGDIR@/error_log. CGI scripts are served via the URL-path . To remove any of the default configuration provided in separate files covered below, replace that file with an empty file rather than removing it from the filesystem, otherwise it may be restored to the original when the package which provides it is upgraded. MPM configuration The configuration file at /etc/httpd/conf.modules.d/00-mpm.conf is used to select the multi-processing module (MPM), which governs how httpd divides work between processes and/or threads at run-time. Exactly one directive must be uncommented in this file; by default the MPM is enabled. For more information on MPMs, see . If using the prefork MPM, the "httpd_graceful_shutdown" SELinux boolean should also be enabled, since with this MPM, httpd needs to establish TCP connections to local ports to successfully complete a graceful restart or shutdown. This boolean can be enabled by running the command: semanage boolean -m --on httpd_graceful_shutdown Module configuration files Module configuration files are provided in the /etc/httpd/conf.modules.d/ directory. Filenames in this directory are by convention prefixed with two digit numeric prefix to ensure they are processed in the desired order. Core modules provide with the httpd package are loaded by files with a prefix to ensure these are loaded first. Only filenames with a suffix in this directory will be processed. Other provided configuration files are listed below. /etc/httpd/conf.modules.d/00-base.conf The set of core modules included with httpd which are all loaded by default. /etc/httpd/conf.modules.d/00-optional.conf The set of non-core modules included with httpd which are not loaded by default. /etc/httpd/conf.modules.d/00-systemd.conf This file loads which is necessary for the correct operation of the httpd.service service, and should not be removed or disabled. Other configuration files Default module configuration files and site-specific configuration files are loaded from the /etc/httpd/conf.d/ directory. Only files with a suffix will be loaded. The following files are provided: /etc/httpd/conf.d/userdir.conf This file gives an example configuration for to map URLs such as to /home/jim/public_html/. Userdir mapping is disabled by default. /etc/httpd/conf.d/autoindex.conf This file provides the default configuration for which generates HTML directory listings when enabled. It also makes file icon image files available at the URL-path. /etc/httpd/conf.d/welcome.conf This file enables a "welcome page" at if no content is present in the default documentation root /var/www/html. /etc/httpd/conf.d/ssl.conf (present only if is installed) This file configures a TLS listening on port . If the default configuration is used, the referenced test certificate and private key are generated the first time httpd.service is started; see httpd-init.service8 for more information. Instantiated services As an alternative to (or in addition to) the httpd.service unit, the instantiated template service httpd@.service unit file can be used, which starts httpd using a different configuration file to the default. For example, systemctl start httpd@foobar.service will start httpd using the configuration file /etc/httpd/conf/foobar.conf. See httpd@.service8 for more information.
