Custom PHP 5.3.1 with APC and XDEBUG on (Dreamhost) Shared Host

I’ve recently been setting up my new dreamhost for symfony projects deployment and the only thing the default PHP is missing is the support for APC (alternate php cache). So after looking at the dreamhost wiki I cleaned up and added some features to the one of the install scripts. Here it is for your/mine (future) commodity.

    Hi,
    does this script create a custom php install with APC working by itself or do I need to modify something else to make it work? I’d like to use APC for magento and all the other scripts for installing php and APC on dreamhost failed to install…
    Thanks

      hi,
      well, you should be able to run it as it is, but you might want to have a look at the 3 “#@todo Update” lines and decide if the settings suits you.

      hope it helps

      Cheers, Marco

    Thanks a lot it works! One last question: Magento doesn’t support php5.3 very well… I’d like to install 5.2. Is it sufficient change PHP=”php-5.3.1″ to PHP=”php-5.2.12″ (for example) at the 1 “#@todo Update” or are there other settings to customize and how?
    I’d really appreciate if you could answer this question, hope it doesn’t bother you too much.
    Thanks a lot.

    Script blocks when downloading Curl, there must be something with their site cause i cannot reach it. I’ll try later and I’ll tell you.

  4. Emmanuele says:

    It blocks during Php 5.2.12 installation: this is the error -> INSTALLING PHP...

    cp: cannot stat `/home/milchstore/mycompiles/build/php-5.2.12/php.ini-production': No such file or directory

  5. marco says:

    hi, it means that it cannot find the php.ini-production file in the $BUILDDIR.
    Check line 245 and adapt it to php.ini-recommended or php.ini-dist (depending on your needs)

    cheers

    Is it just me or is APC not actually functional? I see that it is enabled, however if you look at apc.php there is never any entries other than apc.php itself, and apc start time is the whenever the script ran. I’m sure there is a way around this, but what am I missing?

    • marco says:

      mmm haven’t had a chance to play with apc (and I’m no apc expert either…) since then due to lack of time… i just cleaned up the install script using the settings from the scripts on wiki.dreamhost but looking at a phpinfo it all seams to work… i’ll have a look asap

  7. dave says:

    yea, it works fine, except i believe php as cgi runs as a new instance of php each time, hence no shared memory. (well that’s what I’ve gathered from other research I’ve done)

    Take a look at that apc.php file, the output will let you know whether apc is doing anything for you or not

    Thanks for your efforts btw, the script worked great.

  8. dave says:

    According to this: http://www.brandonturner.net/blog/2009/07/fastcgi_with_php_opcode_cache/#implementation

    One needs to do quite a bit more to get PC properly functioning with PHP /fastcgi. I don’t think those steps are possible as a user account on dreamhost, but if someone knows better, I’m all ears.

    Thank you for putting this together… It really helped me out!

    I use Drupal and some modules would like to have PECL upload progress.

    How could it be added to build script and can you provide a solution for such integration?

  13. GeorgeK says:

    Did anyone use this installation to debug with Xdebug ?

    I use the following configuration in the php.ini
    end_extension_ts-
    xdebug.remote_enable=on
    xdebug.remote_handler=dbgp
    xdebug.remote_host=
    xdebug.remote_port=

    Alas I it doesn’t work and before I spend more time on it I would like to know if this port opening is even allowed?

    Any help will be very welcomed

  14. GeorgeK says:

    My message got scrambled, as stated I using the following configuration in the php.ini

    end_extension_ts=[absolute path to xdebug.so]
    xdebug.remote_enable=on
    xdebug.remote_handler=dbgp
    xdebug.remote_host=[domain name]
    xdebug.remote_port=[port of my choosing]

    @daniel http://blog.ayanray.com/2010/04/custom-php-install-on-dreamhost-shared-hosting/ suggests using a UNIX texteditor to avoid this problem, are you working your files on a win machine and then uploading them?

    @MacMladen you can remove the –without-pear switch on line 92 so your php will have pear and you can use PECL

    @GeorgeK I did play around a bit but not much. (short in time….)

  16. Typically I actually do not post on weblogs, although I would like to state that this article seriously obligated me to do so! nice post.

    I got the script to run without errors, but APC is not showing up as installed. Any suggestions? Is there steps not listed here that I was supposed to follow? Thanks!
