CentOS compile and install httpd-2.4 and 2.4 versions of the 6.5 features introduced
httpd-2.4’s new features:
1) MPM is loaded at run-time support;
–enalbe All-mpm-shared –with-mpm = prefork = {| worker | Event}
2) Support Event mpm
3) asynchronous read and write
4) in each module and each directory separately use a different log levels
5) configure each request: <If>, <Else if>
6) Enhanced expression parser
7) millisecond keep alive the timeout
8) FQDN based virtual hosts NameVirtualHost directive is no longer needed;
9) supports user-defined variables
Additional modules :
mod_proxy_fcgi: support for ways to connect with fastcgi backend php
mode_ratelimit: speed limit, restrict user access to the transmission rate
mod_request: user requests to do more filtering
mod_remoteip: user access to IP addresses have more control
Modify some configuration mechanism :
No longer supports the use of order, allow, deny ip based access control definitions, to require
Dependencies :
Because httpd program relies on apr and apr-util so before installing httpd need to install apr and apr-util, apr yum source centos6.5 provided for httpd 1.3.9 version 1.4.0 version supports more than needed, so apr and apr-util also need to be manually installed
yum install openssl*
yum -y install arp apr-devel apr-util apr-util-devel pcre pcre-devel (Important one )
yum groupinstall ‘Development tools’
yum groupinstall ‘Server Platform Development’
