II. install httpd: httpd installation depends on apr and apr-util. Therefore, you must install these two files before installation.

Httpd-2.4.9.tar.bz2

Apr-1.5.0.tar.bz2

Apr-util-1.5.3.tar.bz2


[Root @ www ~] # Yum install pcre-devel-y

[Root @ www ~] # Tar xf apr-1.5.0.tar.bz2

[Root @ www ~] # Cd apr-1.5.0

[Root @ www apr-1.5.0] # ../configure -- prefix =/usr/local/apr

[Root @ www apr-1.5.0] # make & make install


[Root @ www ~] # Tar xf apr-util-1.5.3.tar.bz2

[Root @ www ~] # Cd apr-util-1.5.3

[Root @ www apr-util-1.5.3] #./configure -- prefix =/usr/local/apr-util -- with-apr =/usr/local/apr/

[Root @ www apr-1.5.0] # make & make install

[Root @ www httpd-2.4.9] #. /configure -- prefix =/usr/local/apache -- sysconfdir =/etc/httpd24 -- enable-so -- enable-ssl -- enable-cgi -- with-zlib -- with-pcre -- enable -rewrite -- with-apr =/usr/local/apr -- with-apr-util =/usr/local/apr-util/-- enable-modules = most -- enable-mpms- shared = all -- with-mpm = event

[Root @ www httpd-2.4.9] make & make install



-- Prefix =/usr/local/apache <=========== specify the installation path

-- Sysconfdir =/etc/httpd24 <============= storage location of the configuration file

-- Enable-so -- enable-ssl -- enable-cgi <=== enable so, ssl, cgi

-- Enable-rewrite <============================ enable the font setting function

-- With-apr =/usr/local/apr <============= where to find apr during installation

-- With-apr-util =/usr/local/apr-util/<= where to find apr-util during installation

-- Enable-mpms-shared = all <========= edit the mpms function

-- With-mpm = event <======================== specify the event mode for php



[Root @ www httpd-2.4.9] # cd/etc/rc. d/init. d

[Root @ www init. d] # cp httpd httpd24


[Root @ www init. d] # vim httpd24


# Path to the apachectl script, server binary, and short-form for messages.

Apachectl =/usr/local/apache/bin/apachectl <= around 40 rows. change the original path to this

Httpd =$ {HTTPD-/usr/local/apache/bin/httpd} <=== specify a new path



[Root @ www init. d] # chkconfig -- add httpd24

[Root @ www init. d] # chkconfig -- list httpd24

Httpd24 0: off1: off2: off3: off4: off5: off6: off

Export PATH =/usr/local/apache/bin: $ PATH


[Root @ www ~] #./Etc/profile. d/httpd. sh


[Root @ www ~] # Vim/etc/httpd24/httpd. conf

# Do not add a slash at the end of the directory path. If you point

# ServerRoot at a non-local disk, be sure to specify a local disk on

# Mutex directive, if file-based mutexes are used. If you want to share

# Same ServerRoot for multiple httpd daemons, you will need to change

# Least PidFile.

#

ServerRoot "/usr/local/apache"

PidFile "var/run/httpd. conf" <= About 40 rows. add the pidFile


[Root @ www ~] # Service httpd24 start

Starting httpd: [OK]



Install the php Server

File to be prepared

Php-5.4.26.tar.bz2

Xcache-3.0.3.tar.bz2

PhpMyAdmin-4.0.5-all-languages.zip



[Root @ www ~] # Tar xf php-5.4.26.tar.bz2

[Root @ www php-5.4.26] # make & make install

[Root @ www php-5.4.26] # cp php. ini-production/etc/php. ini

Edit configuration file

[Root @ www php-5.4.26] # vim/etc/httpd24/httpd. conf

There are two rows below AddType at about 382 rows

AddType application/x-httpd-php. php


AddType application/x-httpd-php-source. phps


Change the value to the following at around 252 rows:

DirectoryIndex index. php index.html
