Httpd2.4 Introduction and CenOS6.6 under compilation and installation

CentOS7has been provided in the imagehttpd2.4of therpmPackage,httpd2.4relative tohttpd2.2There is a big improvement inCentOS6only through theApacheThe official website provides the source code package to compile the installation.

httpd2.4 new features:

MPM Support Run DOS mechanism;

Support Event MPM ;

Support asynchronous read and write;

Support each module and each directory to use the respective log level;

per request configuration; <If>

Enhanced version of the expression parser;

support for millisecond-level keepalive Timeout ;

based on FQDN virtual hosts are no longer required Namevirtualhost directive;

Support user-defined variables;

New module:

mod_proxy_fcgi# with the PHP combination of modules;

mod_ratelimit# a module that restricts the download rate;

mod_remoteip# setting up a remote client IP ;

Modifying the configuration mechanism: no longer supports the use of order,allow, deny todefine IP- based access control, instead of require;

Compile and install Httpd2.4:

httpd2.4 depends on Apr and apr-util,1.4 above, so need to compile and install together;

Apr:apacheportableruntime,Apache Portable runtime;

Official website: apr.apache.org

Lab Environment:

System version: CentOS 6.6x86_64;

httpd Source Package:httpd-2.4.16.tar.bz2;

Apr Source Package:apr-1.5.2.tar.bz2;

Apr-util Source Package:apr-util-1.5.4.tar.bz2

Experimental Prerequisites:

turn off the firewall and SELinux;

Install the compilation environment;

# yum Groupinstall "Server Platform Development" "Developmenttools"

Experimental process:

First, installation services;

Apr:

# Tar XF apr-1.5.2.tar.bz2# cd apr-1.5.2#./configure--prefix=/usr/local/apr# make && make install

Apr-util:

# Tar XF apr-util-1.5.4.tar.bz2# cd apr-util-1.5.4#./configure--prefix=/usr/local/apr-util--with-apr=/usr/local/apr /--with-apr=/usr/local/apr/: Specify Apr installation location; # make && make install

httpd:

# Tar XF httpd-2.4.16.tar.bz2# cd httpd-2.4.16#./configure--prefix=/usr/local/apache--sysconfdir=/etc/httpd-- Enable-so--enable-ssl--enable-cgi--enable-rewrite--with-zlib--with-pcre--with-apr=/usr/local/apr-- With-apr-util=/usr/local/apr-util--enable-modules=all--enable-mpms-shared=all--with-mpm=event# make && Make install

HTTPD Compilation parameter explanation:

--prefix=/usr/local/apache: Installation location;--sysconfdir=/etc/httpd: Configuration file location;--ENABLE-SO: Support DSO dynamic loading module;--ENABLE-SSL: Support ssl/ TLS, can implement HTTPS protocol access, need to install OPENSSL-DEVEL;--ENABLE-CGI: support CGI script;--enable-rewrite: support URL rewrite;--with-zlib: Use the specified zlib compression library, do not specify a path The path will be automatically searched;--with-pcre: Enhanced Regular expression analysis tool using the specified pcre library; Do not specify paths will automatically look for required installed PCRE-DEVEL;--WITH-APR=/USR/LOCAL/APR: Specify the dependent APR program installation location ;--with-apr-util=/usr/local/apr-util: Specifies the installation location of the dependent Apr-util program;--enable-modules=all: Supports dynamic enable module; All: Everything, most: common ;--enable-mpms-shared=all: Compile and Share module;--with-mpm=event: module enabled by default; {prefork|worker|event}

Second, the parameter configuration;

Next is the configuration of the parameters after the installation is complete;

Add environment variables and reread the files:

# vim/etc/profile.d/httpd.sh> Export path=/usr/local/apache/bin: $PATH # source/etc/profile.d/httpd.sh

Export header file;

# LN-SV/USR/LOCAL/APACHE/INCLUDE/USR/INCLUDE/HTTPD

Export man manual;

# vim/etc/man.config> Manpath/usr/local/apache/man

Start the service and view the listening port;

# Apachectl start# SS–TNL

To provide a service script:

you can use the script modifications provided with the RPM package installation:

Modify the master configuration file to specify pidfile;

# vim/etc/httpd/httpd.conf> Pidfile "/var/run/httpd.pid"

Script execution permissions;

# chmod +X/ETC/RC.D/INIT.D/HTTPD

Add services, test scripts;

# chkconfig httpd–add# chkconfig httpd on

# service httpd stop# service httpd start# service httpd restart# service httpd Reload

httpd2.4 configuration file:

#/etc/httpd24: Compile the configuration file directory specified at the time of installation; #/etc/httpd24/httpd.conf: Master Profile #/etc/httpd24/extra/httpd-default.conf: Default profile, Ke    Epalive, Accessfilename and other settings; #/etc/httpd24/extra/httpd-userdir.conf: User directory profile; #/etc/httpd24/extra/httpd-mpm.conf    : mpm config file; #/etc/httpd24/extra/httpd-ssl.conf:ssl config file, providing HTTPS protocol for site; #/etc/httpd24/extra/httpd-vhosts.conf : Virtual host configuration file; #/etc/httpd24/extra/httpd-info.conf:server-status page configuration file;

At this point, the httpd2.4 installation configuration is complete andthe httpd2.4 configuration is roughly the same as httpd2.2 .
