Configure Apache http Server In Linux 5.1. Overview of apache httpd conf file:The httpd.conf is the primary configuration file in Apache Web Server in RHEL and CentOS. It is located at /etc/httpd/conf folder. It is a text file and consist of directives, containers and comments.Example of directives in httpd.conf: ServerRootListenIncludeAllowOverrideExample of containers:Containers enclose one or more directives. AllowOverride noneRequire all deniedExample of comments: # Listen: Allows you to bind Apache to specific IP addresses and/or# ports, instead of the default. See also the# directive.5.2 Configure Apache httpd.conf configuration fileThere are a few apache configuration need to alter before you can start running the apache web server. All the main configuration file is in httpd.conf file: # vi /etc/httpd/conf/httpd.confModify below directives and matches the value to your web server environment:ServerAdmin email address This is where your problem with the server should be e-mailed.
This address appears on some server-generated pages, such as error documents. For example: ServerAdmin [email protected] directory-path The top level directory for Apache server content. The apache user requires read access to any files and read and execute access to the directory and any of its sub-directories. Do not place a slash at the end of the directory path.For example: DocumentRoot /var/www/htmlServerName FQDN:port Specifies the fully qualified domain name or IP address of the httpd server and an optional port on which the server listens. The FQDN must be resolvable to an IP address.If you do not specify a FQDN, the server performs a reverse-name lookup on the IP address. If you do not specify a port, the server uses the port corresponding to the incoming request.For example: ServerName www.ehowstuff.local:80AllowOverride Directive In Apache 2.4, AllowOverride is set to None by default.
When AllowOverride is set to None, then.htaccess files are completely ignored. In this case, the server will not even attempt to read.htaccess files in the filesystem.When AllowOverride directive is set to All, then any directive which has the.htaccess Context is allowed in.htaccess files.htaccess is short for Hypertext Access, is a configuration file for use on web servers running the Apache Web Server software. Where to specify VirtualHost directive? Virtual hosts are configured using the block inside the main configuration.For ease of administration, i would recommend this virtual host blocks are not defined inside /etc/httpd/conf/httpd.conf.
