Running A Basic Apache Web Server

Learn to host your own website with Apache, a solid, well-known, and easy-to-configure web server. The Prerequisites. The directives discussed in this article will need to go either in your main server configuration file (typically in a section), or in per-directory configuration files (.htaccess files). Gadmei others driver download. If you plan to use.htaccess files, you will need to have a server configuration that permits putting authentication directives in these files.

Apache Web Server Tutorial

What is Apache

Apache is the most widely used web server software. Developed and maintained by Apache Software Foundation, Apache is an open source software available for free. It is fast, reliable, and secure. It can be highly customized to meet the needs of many different environments by using extensions and modules. Most hosting providers companies use Apache as their web server software.

Apache Most Features

Unix Threading

On Unix systems with POSIX threads support, Apache httpd can now run in a hybrid multiprocess, multithreaded mode. This improves scalability for many, but not all configurations.

New Build System

The build system has been rewritten from scratch to be based on autoconf and libtool. This makes Apache httpd’s configuration system more similar to that of other packages.

Multiprotocol Support

Apache HTTP Server now has some of the infrastructure in place to support serving multiple protocols. mod_echo has been written as an example.

Better support for non-Unix platforms

Apache HTTP Server 2.0 is faster and more stable on non-Unix platforms such as BeOS, OS/2, and Windows. With the introduction of platform-specific multi-processing modules (MPMs) and the Apache Portable Runtime (APR), these platforms are now implemented in their native API, avoiding the often buggy and poorly performing POSIX-emulation layers.

New Apache httpd API

The API for modules has changed significantly for 2.0. Many of the module-ordering/-priority problems from 1.3 should be gone. 2.0 does much of this automatically, and module ordering is now done per-hook to allow more flexibility. Also, new calls have been added that provide additional module capabilities without patching the core Apache HTTP Server.

IPv6 Support

On systems where IPv6 is supported by the underlying Apache Portable Runtime library, Apache httpd gets IPv6 listening sockets by default. Additionally, the Listen, NameVirtualHost, and VirtualHost directives support IPv6 numeric address strings (e.g., “Listen [2001:db8::1]:8080”).

Apache Filtering

Apache httpd modules may now be written as filters which act on the stream of content as it is delivered to or from the server. This allows, for example, the output of CGI scripts to be parsed for Server Side Include directives using the INCLUDES filter in mod_include. The module mod_ext_filter allows external programs to act as filters in much the same way that CGI programs can act as handlers.

Multilanguage Error Responses

Error response messages to the browser are now provided in several languages, using SSI documents. They may be customized by the administrator to achieve a consistent look and feel.

Simplified configuration

Many confusing directives have been simplified. The often confusing Port and BindAddress directives are gone; only the Listen directive is used for IP address binding; the ServerName directive specifies the server name and port number only for redirection and vhost recognition.

Native Windows NT Unicode Support

Apache httpd 2.0 on Windows NT now uses utf-8 for all filename encodings. These directly translate to the underlying Unicode file system, providing multilanguage support for all Windows NT-based installations, including Windows 2000 and Windows XP. This support does not extend to Windows 95, 98 or ME, which continue to use the machine’s local codepage for filesystem access.

Regular Expression Library Updated

Apache httpd 2.0 includes the Perl Compatible Regular Expression Library (PCRE). All regular expression evaluation now uses the more powerful Perl 5 syntax.

Apache Most Module

mod_proxy_fcgi : FastCGI Protocol backend for mod_proxy
mod_proxy_scgi : SCGI Protocol backend for mod_proxy
mod_proxy_express : Provides dynamically configured mass reverse proxies for mod_proxy
mod_remoteip: Replaces the apparent client remote IP address and hostname for the request with the IP address list presented by a proxies or a load balancer via the request headers.
mod_heartmonitor, mod_lbmethod_heartbeat:Allow mod_proxy_balancer to base loadbalancing decisions on the number of active connections on the backend servers.
mod_proxy_html:Formerly a third-party module, this supports fixing of HTML links in a reverse proxy situation, where the backend generates URLs that are not valid for the proxy’s clients.
mod_sed : An advanced replacement of mod_substitute, allows to edit the response body with the full power of sed.
mod_auth_form: Enables form-based authentication.
mod_session : Enables the use of session state for clients, using cookie or database storage.
mod_allowmethods: New module to restrict certain HTTP methods without interfering with authentication or authorization.
mod_lua: Embeds the Lua language into httpd, for configuration and small business logic functions. (Experimental)
mod_log_debug: Allows the addition of customizable debug logging at different phases of the request processing.
mod_buffer: Provides for buffering the input and output filter stacks
mod_data : Convert response body into an RFC2397 data URL
mod_ratelimit : Provides Bandwidth Rate Limiting for Clients
mod_request : Provides Filters to handle and make available HTTP request bodies
mod_reflector : Provides Reflection of a request body as a response via the output filter stack.
mod_slotmem_shm : Provides a Slot-based shared memory provider (ala the scoreboard).
mod_xml2enc : Formerly a third-party module, this supports internationalisation in libxml2-based (markup-aware) filter modules.
mod_macro :(available since 2.4.5) Provide macros within configuration files.
mod_proxy_wstunnel : (available since 2.4.5) Support web-socket tunnels.
mod_authnz_fcgi : (available since 2.4.10) Enable FastCGI authorizer applications to authenticate and/or authorize clients.
mod_http2 : (available since 2.4.17) Support for the HTTP/2 transport layer.
mod_ssl : mod_ssl can now be configured to use an OCSP server to check the validation status of a client certificate. The default responder is configurable, along with the decision on whether to prefer the responder designated in the client certificate itself. mod_ssl now also supports OCSP stapling, where the server pro-actively obtains an OCSP verification of its certificate and transmits that to the client during the handshake .mod_ssl can now be configured to share SSL Session data between servers through memcached EC keys are now supported in addition to RSA and DSA. Support for TLS-SRP (available in 2.4.4 and later).
mod_proxy: The ProxyPass directive is now most optimally configured within a Location or LocationMatch block, and offers a significant performance advantage over the traditional two-parameter syntax when present in large numbers. The source address used for proxy requests is now configurable. Support for Unix domain sockets to the backend (available in 2.4.7 and later).
mod_proxy_balancer: More runtime configuration changes for BalancerMembers via balancer-manager Additional BalancerMembers can be added at runtime via balancer-manager Runtime configuration of a subset of Balancer parameters BalancerMembers can be set to ‘Drain’ so that they only respond to existing sticky sessions, allowing them to be taken gracefully offline. Balancer settings can be persistent after restarts.
mod_cache: The mod_cache CACHE filter can be optionally inserted at a given point in the filter chain to provide fine control over caching. mod_cache can now cache HEAD requests. Where possible, mod_cache directives can now be set per directory, instead of per server. The base URL of cached URLs can be customised, so that a cluster of caches can share the same endpoint URL prefix. mod_cache is now capable of serving stale cached data when a backend is unavailable (error 5xx). mod_cache can now insert HIT/MISS/REVALIDATE into an X-Cache header.
mod_include : Support for the ‘onerror’ attribute within an ‘include’ element, allowing an error document to be served on error instead of the default error string.
mod_cgi, mod_include, mod_isapi :Translation of headers to environment variables is more strict than before to mitigate some possible cross-site-scripting attacks via header injection. Headers containing invalid characters (including underscores) are now silently dropped. Environment Variables in Apache has some pointers on how to work around broken legacy clients which require such headers. (This affects all modules which use these environment variables.).
mod_authz_core :Authorization Logic Containers Advanced authorization logic may now be specified using the Require directive and the related container directives, such as <RequireAll>.
mod_rewrite:mod_rewrite adds the [QSD] (Query String Discard) and [END] flags for RewriteRule to simplify common rewriting scenarios.Adds the possibility to use complex boolean expressions in RewriteCond.Allows the use of SQL queries as RewriteMap functions.
mod_ldap, mod_authnz_ldap :mod_authnz_ldap adds support for nested groups.mod_ldap adds LDAPConnectionPoolTTL, LDAPTimeout, and other improvements in the handling of timeouts. This is especially useful for setups where a stateful firewall drops idle connections to the LDAP server.
mod_ldap adds LDAPLibraryDebug to log debug information provided by the used LDAP toolkit.
mod_info :mod_info can now dump the pre-parsed configuration to stdout during server startup.
mod_auth_basic:New generic mechanism to fake basic authentication (available in 2.4.5 and later).
