Centos 6.7 apache2.4.x compile and install and configure virtual hosts, SSL access, user-based access control

apache2.4 new features

Loadable MPMs
At compile time can be made ??of a plurality of removable of MPM. The choice of MPM can also be configured at run time.

Event MPM
full support Event MPM. This is just test version of Apache 2.2.
Asynchronous support
better asynchronous read / write support in support of MPM and platforms.
Per-module and per-directory LogLevel configuration
LogLevel can be set different for different modules and directories.
On debug logging levels to increase the trace1 trace8 tracking method.
Per-Request configuration Sections
<If>, <ElseIf>, and <Else> block can be used in every request can be set on the configuration level.
General-purpose expression parser
new expression parser allows the instruction (eg SetEnvIfExpr, RewriteCond, Header, <If>, etc.)
using a common syntax to specify complex criteria.

KeepAliveTimeout in milliseconds
now in milliseconds (milliseconds) Set the connection holding time (KeepAliveTimeout).
NameVirtualHost directive is no longer needed, it has been deprecated.
Override Configuration
AllowOverrideList allow new directory (.htaccess allowed directory) a more fine-grained control.
Config file variables
can now define and use variables in the configuration file.

Reduced memory usage though adds many new features, version 2.4.x Apache was successfully reduced memory footprint (compared to 2.2.x version).

Ready to work

Before compiling still need to do some preparation. 1, if there apache2.2.x apache2.2.x then we need to deactivate and remove it before you start automatically on a server 2,
apache2.4.x dependent apr also requires version 1.4 or more, so before compiling further QPR need to compile high version 3, making apache2.4.x available boot startup scripts and configuration, etc.

yum groupinstall “Development tools” “Server Platform Development” -y

service httpd stop
chkconfig httpd off
chkconfig –list | grep httpd
