centos 5: config apache to execute php scripts/pages

most of my googling odysseies lead me to articles which talk about compiling apache & php from the source as this is touted to be more flexible. But the problem we have is this...we already have an apache 2 web server running. Now how do we serve php pages of it...

PS: i believe we even have php installed...

If you already have php installed it should work out of the box, you do not need to do anything.

Check using

Code:

rpm -qi php

cat /etc/httpd/conf.d/php.conf

Here is the output of both commands:

Code:

$ rpm -qi php

The php package contains the module which adds support for the PHP

language to Apache HTTP Server.

Summary    : The PHP HTML-embedded scripting language. (PHP: Hypertext Preprocessor)

Description :

PHP is an HTML-embedded scripting language. PHP attempts to make it

easy for developers to write dynamically generated webpages. PHP also

offers built-in database integration for several commercial and

non-commercial database management systems, so writing a

database-enabled webpage with PHP is fairly simple. The most common

use of PHP coding is probably as a replacement for CGI scripts.



The php package contains the module which adds support for the PHP

language to Apache HTTP Server.

Code:

$ cat /etc/httpd/conf.d/php.conf

#

# PHP is an HTML-embedded scripting language which attempts to make it

# easy for developers to write dynamically generated webpages.

#



LoadModule php5_module modules/libphp5.so



#

# Cause the PHP interpreter to handle files with a .php extension.

#

AddHandler php5-script .php

AddType text/html .php



#

# Add index.php to the list of files that will be served as directory

# indexes.

#

DirectoryIndex index.php



#

# Uncomment the following line to allow PHP to pretty-print .phps

# files as PHP source code:

#

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

Yet I am not getting the php page served...don't know if the php code is incorrect either...pasting the code here for reference:

PHP Code:




<html> 
<body> 
 
<?php phpinfo(); ?> 
 
</body> 
</html>

This should do, test.php with the following in it

Code:

<?php

phpinfo();

?>

it still doesn't work...4got to mention wher i've kept my php file...
in /var/www/html/test folder I've created a page called index.php with the above code.

In the browser I an typing http://localhost/test/index.php still nt giving me an output...

Code:

tail /var/log/httpd/access_log /var/log/httpd/error_log

Code:

$ tail /var/log/httpd/access_log /var/log/httpd/error_log

There is a permissions issue, i am guessing selinux what is the output of sestatus ?

don't understand what is selinux in the context?

You want help supply the output of

Code:

sestatus

Code:

$ sestatus

SELinux status:                disabled

Thats very wierd given the errors

Code:

Check the file and directory ownership

Code:

ls -l /var/www/html

ls -l /var/www/html/test/

Code:

$ ls -l /var/www/html

total 12

drwxr-xr-x 2 root root 4096 Dec  9 15:27 test

$ ls -l /var/www/html/test

total 12

-rw------- 1 root root 55 Dec  9 15:27 index.php

-rw------- 1 root root 57 Dec  9 15:26 index.php~

-rwxr-xr-x 1 root root 20 Dec  9 04:08 test.html

-rw------- 1 root root  0 Dec  9 04:07 test.html~

$

The permissions are incorrect fix them using

Code:

chmod a+r /var/www/html/test/index.php

Thanx tht worked!!!

Don't understand those permissions I've to set tho. Are there any articles that can come in handy?

Isn't there a more direct way? I mean I am looking at directly creating php files and expecting them to get deployed...straight. So those files should have the correct permissions...I don't want to create a file and then change its permission always...OR, is this how its done always?!!

Okay, a quick explanation for you.

You created the file as root with read, write permissions for the owner (rw-------)

The webserver is running as user apache, so is unable to read the file.

The command i gave u changes the file permissions to be readable by the group and others (readable by anyone)
