Compiling PHP 5.1.6 from source - php -v and phpinfo() version discrepancy

Hi, I have just bought a VPS running Ubuntu and I need to install the LAMP stack with PHP 5.1.6. The VPS came with no PHP installed (checked this from the shell with php -v) and with Apache/2.2.12 installed. I installed PHP 5.1.6 from source and compiled it with Apache 2.2 (using libapache2-mod-php5), tried a phpinfo() test which worked fine, however, phpinfo() shows the PHP version as 5.2.1 (with JSON enabled), whereas running php-v in the shell shows as 5.1.6. Anyone any ideas what might be happening here? I need to ensure I am running PHP 5.1.6.

Thanks in advance for any help!

I guess that apache uses the php module from libapache2-mod-php5, that's why you get the wrong version.
You didn't mention the options used to compile php, but you should have used "--with-apxs2=/path/to/apxs" in the ./configure script of php. This way the compiled php5_module will use the correct php.

Thanks bathory, you're right - I didn't specify any options during configuration. I ran ./configure again using "--with-apx2=/path/to/apxs" - but after restarting apache i still have PHP 5.2.1 showing. Do i have to remove the libapache2-mod-php5 module (not sure how to do this other than reinstalling apache) and rerun ./configure?

I guess you've run "make && make install" after ./configure.
In that case you can manually copy libphp5.so to the location where your apache looks for its modules. You can find libphp5.so in the subdir libs/ in the directory you built php. The apache modules location can be found from the LoadModule directive in httpd.conf.
Then add:

Code:

LoadModule php5_module /path/to/apache/modules/libphp5.so

There is no need to uninstall anything, just comment out the LoadModule that loads the wrong php_module.

Yes, I ran make and make install. However, I can only find one libphp5.so file and it's in /usr/lib/apache2/modules/libphp5.so - which is what Apache is already loading, so if i understand correctly this is the one i want to replace - but i can't find the correct libphp5.so to replace it with. Running find / -name libphp5.so only gives the one result.

Thanks again for your help bathory and apologies if this is utterly basic stuff i'm getting stuck with!

It should be there. Actually libphp5.so should be present in 2 subdirectories: libs/ and .libs/, so I guess the the module is not built.

Are you sure make finished without errors? Could you run

Code:

make distclean

and redo the procedure, posting here the whole ./configure command you use and the last couple of lines of make?

Ok, I ran make distclean, the following for configure:

Code:

./configure --with-apx2=/path/to/apxs

Then the last few lines of make are as follows (this has been the same each time i've tried):

Code:

Build complete.

(It is safe to ignore warnings about tempnam and tmpnam).

When running make install, I get the following:

Code:

Installing PHP SAPI module:      cgi

Installing PHP CGI into: /usr/local/bin/

Installing build environment:    /usr/local/lib/php/build/

Installing header files:          /usr/local/include/php/

Installing helper programs:      /usr/local/bin/

  program: phpize

  program: php-config

Installing man pages:            /usr/local/man/man1/

  page: phpize.1

  page: php-config.1

Installing PEAR environment:      /usr/local/lib/php/

[PEAR] Archive_Tar    - already installed: 1.3.1

[PEAR] Console_Getopt - already installed: 1.2

[PEAR] PEAR          - already installed: 1.4.9

Wrote PEAR system config file at: /usr/local/etc/pear.conf

You may want to add: /usr/local/lib/php to your php.ini include_path

Installing PDO headers:          /usr/local/include/php/ext/pdo/

Then, "find / -name libphp5.so" just returns /usr/lib/apache2/modules/libphp5.so

It looks like Apache is still using PHP version 5.2.1 which Ubuntu bundles with the apache php module.

Oups, I've made a typo and you didn't notice it also. It's "--with-apxs2=/path/to/apxs" (note also that you have to replace /path/to with the actual path to apxs).
Please also note, that you might need mysql support (it's a LAMP after all) and perhaps support for other things, so your ./configure must contain these options. Since the old phpinfo() still works, take a look at the beginning of it to have an idea of what was added to the old php.

Sorry for the mistake
