CentOS 6 Installation httpd-2.4 instructions:

httpd-2.4 relies on newer versions of apr-1.4 and above (Apache Portable Runtime) and apr-util-1.4 versions above. CentOS 6 only offers apr-1.3, apr-util-1.3 versions. So CentOS 6 needs to compile and install the httpd-2.4 and its dependent apr-1.4 and apr-util-1.4.

httpd-2.4 Compile the installation steps:

1, first to ensure that the machine has installed httpd-2.2 service stopped, if not installed it is better.

~] #service httpd stop~] #chkconfif httpd off

2, build the compilation installation environment: must install development tools,server Platform Development, development package Pcre-devel

~] #yum Groupinstall "Development Tools" "Server Platform Development" ~] #yum-y install pcre-devel Description: The configuration of the Yum source is not introduced here, the reader can Install according to your own situation.

3, the compilation installs apr-1.4 above (I use the par-1.5 version to do the test), obtains to apr-1.4 above package. After decompression into the apr-1.5 directory, to compile and install:

~]# CD ~/apr-1.5.0~]#./configure--prefix=/usr/local/apr #环境检查--prefidx Specify the path to the compilation installation ~]# make && make Insta ll #编译, after successful copying files to/USR/LOCAL/APR

4. Compile and install apr-util-1.5

~]# CD ~/apr-util-1.5.3#./configure–prefix=/usr/local/apr-util-–with-apr=/usr/local/apr #环境检查--prefidx Specify compilation installation The path--WITH-APR specifies the package that depends on the ~]# made && make install #编译, and the file is copied to/usr/local/apr-util after success

5. Compilation and installation and environment configuration

5.1 Compiling the installation

~] #useradd  -r apache     #创建名为apache的用户, create a user group with the same name by default ~]# cd ~/httpd-2.4.9  ~]# ./configure --prefix=/usr/local/apache24 --sysconf=/etc/httpd24 --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=most– enable-mpms-shared=all > --with-mpm=prefork    --sysconf                    : Create its configuration in/etc/ httpd24    --enable-so     --enable-ssl    -- enable-cgi    --enable-rewrite            &NBSP: Support URL rewrite     --enable-mpms-shared=all    : All three modules are compiled.     --with-mpm                   : Set the default mpm    --with-zlib                 &NBSP: Dependent on zlib  available for compression library     --with-pcre                 &NBSP: Support for extended regular expressions      do not specify (=)   Go to the default location      Note:--with/--without  supports or does not support which dependent packages             --enable/--disable  which features are enabled or disabled  ~]# make  && make install     #编译, copy files to/usr/local/apache24 after success

  compiled and installed to this end, what are the files after installation?

~]# cd /usr/local/apache24~]# ls  bin  build  cgi-bin   Conf  error  htdocs  icons  include  logs  man   manual  modules    bin : apache binary Files executable    INCLUDE&NBSP: Message header   icons: Resource storage location   conf: Profile   build: Files generated during installation      ~]# cat /usr/local/apache24/build/config.nice     compile the ./configure  at the time of installation Commands          "./configure"            "--prefix=/usr/local/apache24"          "--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= Most "         "--enable-mpms-shared=all "          "--with-mpm=prefork"           "--sysconf=/ Etc/httpd24 "\

At this point the start service must execute the APACHECTL command to the/usr/local/apache24/bin/directory to manage the httpd process. However, if you need httpd to start as normal as other services, you need to configure the following:

5.2 Environment Configuration

Setting Global environment variables

~] #vim/etc/profile.d/httpd.sh echopath=/user/local/apache24/bin: $PATH

Export Header File

~]# ln-sv/usr/local/apache24/include/usr/include/httpd

'/usr/include/httpd/include ', '/usr/local/apache24/include '

Loading library files

~]# ldconfig-v # Reload library file

~]# ldconfig-p # All library file paths loaded

Service Management Settings

~] #cp/etc/rc.d/init.d/httpd/etc/rc.d/init.d/httpd24~] #vim/etc/rc.d/init.d/httpd24 apachectl=/usr/sbin/apachectl HTTPD=${HTTPD-/USR/LOCAL/APACHE24/BIN/HTTPD} This directory needs to be changed PROG=HTTPD pidfile=${pidfile-/usr/local/apache24/logs/ Httpd.pid} lockfile=${lockfile-/var/lock/subsys/httpd24}

Add it to the boot start

~] #chkconfig –addhttpd24 ~] #chkconfig –list httpd24

Start the service, httpd can use the

~]# Service httpd Start
