Linux Administration: INSTALLING/CONFIGURING APACHE V2 AND PHP V4 THROUGH SOURCE CODE AND MYSQL THROUGH YUM/RPM IN CENTOS 6.2/RHEL5

INSTALLING/CONFIGURING APACHE V2 AND PHP V4 THROUGH SOURCE CODE AND MYSQL THROUGH YUM/RPM IN CENTOS 6.2/RHEL5

Why compile from source

You may ask, why we need to compile PHP and Apache from source when binary RPMs are already available and which don't take much effort to setup. The reason is, it provides you much more flexibility. Instead of being dependent on other people's RPMs you can decide what PHP and Apache functionality you want to enable. Another reason is that these RPMs are weeks or months out of date. When compiling from source, you can also specify the directory where software will be installed. Also, after you see your compiled software working, it really provides great satisfaction. Compilation process is really very straight forward.

Before you start

Before starting to compile Apache and PHP you must uninstall all previous Apache and PHP related RPMs installed on your system

Then download apache 2.0 source and PHP source . These files have .tar.gz extension. Save these files to any directory of your choice. I am using PHP 4.4.9 and Apache 2.0.44/64 and have these files in /usr/src directory.

NOTE: I faced no problems with Apache 2.0.44 and PHP 4.4.9(IN CENT 6.2)

I faced no problems with Apache 2.0.64 and PHP 4.4.9(IN RHEL 5)

I have faced so many problems with Apache 2.0.44 and PHP 4.3.0 /4.3.9in my system (CENT 6.2 64 bit)

but it may work in another machines(like cent os 5 /RHEL5).

Most others faced no problems with Apache 2.0.40 / 2.0.43 and PHP 4.2.3 and Apache 2.0.44 and PHP 4.3.0

YOU MAY GET PROBLEMS WHILE USING BELOW SOURCE CODE

Apache 2.0.48 and PHP 4.3.4

Apache 2.0.39 and PHP 4.2.2

Apache 2.0.39 and PHP 4.2.3 / 4.2.2

Compilation Process

Login as root to follow these steps.

#cd
   /usr/src

download
source code from apache website and unzip in /usr/src

cd
   /usr/src/httpd-2.0.44

#./configure
   --prefix=/wwwroot –enable-so

(OR)

#./configure
   --prefix=/wwwroot --enable-so --enable-deflate --enable-expires
   --enable-headers --enable-rewrite --with-included-apr
   --with-included-apr-util

First
option

--prefix


tells

configure


script that we want Apache to be installed in directory /wwwroot. If
we don't provide a prefix option than it'll be installed in default
location, which is /usr/local/apache2.

I am installing everything in /wwwroot because:

when a new version of PHP and Apache is released, I only have to rename /wwwroot directory to some other name like /wwwrootold and then I can install new versions in /wwwroot directory again. If new installation works properly then I can simply copy configuration files from old directory to /wwwroot.
users new to compiling software from source, after compiling and installing it, try to find a way to uninstall the software. So, benefit of keeping everything at one place is; if someone wants to uninstall Apache and PHP then he just has to delete /wwwroot directory (After stopping Apache, if it is running).

Second option --enable-so tells configure to enable module so, which allows Apache to load shared modules. We need this option because we are compiling PHP as Apache shared module.

Example Apache configure command line looks like this. After configure finishes we have to compile Apache.

YOU MAY GET THIS TYPE OF ERROR

rotatelogs.c:298: warning: implicit declaration of function ‘apr_file_link’

/usr/lib64/apr-1/build/libtool --silent --mode=link gcc -std=gnu99 -pthread

-o rotatelogs rotatelogs.lo /usr/lib64/libaprutil-1.la -ldb-4.7 -lexpat

rotatelogs.o: In function `post_rotate':

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/usr/local/src/httpd-2.0.44/support'

make: *** [all-recursive] Error 1

IF U GET SAME ERROR THEN DOWNLOAD NEW APR AND APR-UTIL FROM INTERNET AND THEN COPY INTO

/usr/local/src/httpd-2.4.1/srclib/

AND
UNZIP RENAME IT TO “apr and apt-util” as

shown
below

cd
/usr/local/src/httpd-2.4.1/srclib/

Installing APR & APR-Utils dependencies :

#wget
   http://mirror-cybernet.lums.edu.pk/pub/apache//apr/apr-util-1.4.1.tar.bz2

#wget
   http://mirror-cybernet.lums.edu.pk/pub/apache//apr/apr-1.4.6.tar.bz2

#tar
   -jxf apr-1.4.6.tar.bz2

#tar
   -jxf apr-util-1.4.1.tar.bz2

#mv
   apr-1.4.6 apr

#mv
   apr-util-1.4.1 apr-util

Lets
configure it now :

#./configure
   --prefix=/wwwroot --enable-so --enable-deflate --enable-expires
   --enable-headers --enable-rewrite --with-included-apr
   –with-included-apr-util

ERROR:

you
may get lot of errors thats depends upon the libraries or
dependencies and other modules first see the error if you get any
errors just type

yum
   install packname*

AGAIN
ERROR :

if
you got same error or different error some dependencies are missing
in your OS. So please check the dependencies and install it through
rpm or yum

OR)

simply
change the source code of apache and try another version in your
system and follow above process

#make

#make
   install

This
will install Apache to /wwwroot directory. Now test your Apache
installation by starting Apache:

#
   /wwwroot/bin/apachectl start-----------for starting apache

#
   /wwwroot/bin/apachectl stop -----------for stoping apache

INSTALLING MYSQL

you
can install mysql through yum or rpm

#yum
   install mysql*

it
will install all packages of my sql

type
below command for changing password of root user of mysql

#mysql
   -u root -p

#PASSWD:**********
   -------it will ask password then enter new password

`Compiling PHP`

Change
to directory where you have downloaded PHP source.

# cd /usr/src

Then we have to extract PHP source files from php-4.4.9.tar.gz file.
To decompress the compressed file use:

# gunzip
   php-4.4.9.tar.gz

You will have a file named php-4.3.0.tar in your current directory. Now to extract its contents use:

# tar -xvf
   php-4.4.9.tar

Both above steps can be completed by using this command:

# tar -zxvf
   php-4.4.9.tar.gz

A new directory php-4.3.0 will be created in your current directory. For me its /usr/src/php-4.3.0.
Now change to this directory:

# cd
   /usr/src/php-4.4.9

./configure --prefix=/wwwroot/php
   --with-apxs2=/wwwroot/bin/apxs
   --with-config-file-path=/wwwroot/php --with-mysql

After

configure


finishes. You have to type

make


to compile PHP:

# make

It
will take several minutes to compile. After make finishes and, no
error etc. is displayed then PHP has been compiled successfully. If
any warning is displayed then, normally, you can ignore it.

After this, if Apache is running stop Apache:

#
   /wwwroot/bin/apachectl stop

Now you can execute make install from within PHP source directory to install PHP to /wwwroot/php directory:

# make
   install

make install will install PHP4 module to Apache's modules sub-directory (/wwwroot/modules) and add a line like this:

AddType
application/x-httpd-php .php

in
/wwwroot/conf/httpd.conf file

To
add this line search for word AddType in httpd.conf file. There will
be a line like this:

AddType application/x-tar .tgz
Below this line add (on a new line):

AddType
application/x-httpd-php .php

Save
this file and then start Apache:

#
   /wwwroot/bin/apachectl start

`Testing the PHP Installation`

Now
create a PHP file named info.php, using any editor like vi or emacs,
in the /wwwroot/htdocs directory and enter three lines, shown below,
in this file. Directory /wwwroot/htdocs is Apache root directory.
Apache publishes all files present in this directory to web users.
This directory can be changed by editing httpd.conf file and changing

DocumentRoot


value to some other directory.

info.php

<?php
phpinfo();
?>

Save this file and then access this file using a web browser

Now
you can copy /usr/src/php-4.4.9/php.ini-dist to /wwwroot/php/
directory as php.ini.

#
   cp /usr/src/php-4.4.9/php.ini-dist /wwwroot/php/php.ini

#
   /wwwroot/bin/apachectl restart

NOTE:

AFTER INSTALLING ALL DEPENDENCIES AND MODULES AND DEPENDENT LIBRARIES ITS WORKING IN MY SYSTEM

IAM NOT SURE IT MAY WORK IT MAY NOT WORK IN YOUR SYSTEM

BUT TRY DIFFERENT DIFFERENT SOURCE CODE OF APACHE AND PHP IN YOUR SYSTEM IT WILL WORK IN YOUR SYSTEM
