php4 and 5 side by side

Someone posted a step by step to do it at http://forums.cpanel.net/showthread.php?t=45908 just a few hours back. There are quite a few other threads here lately that discuss this issue which you may search within the forums. I'd advise that you do it only if you really need it.

 

I also wrote a small script to automatically install PHP5 as a CGI using the same configuration as the already installed PHP4 module. Not really released to public (I just use it on my own servers to keep PHP4 and PHP5 running along side eachother), but here ya go anyway. I'm planning on putting it in my LES program soon, anyway.

Code:

# This script will install PHP5 as a CGI on a cPanel server using the same configure
# selections as the already built PHP4.  You can have PHP scripts utilize the PHP5
# engine by using the .php5 extension.

chown root:wheel /usr/local/cpanel/cgi-sys/php5

I'm concerned about using the group wheel, why is that done?

If I look at the suexec patch:

* READ THIS BEFORE CONTINUING!!
*
* The patch below adds a feature which makes it possible to run "shared"
* scripts. Suppose you are a systems admin for $large hosting provider and
* you want to offer your customers some standard scripts. These scripts would
* cause a security violation based on the uid owner of the script.
*
* This patch makes it possible to "trust" a certain user/group. Look below to
* define the user/group ID.

So... how does this trust translate?

What about this vulnerability?

Ok, I guess it's not a problem if you run phpsuexec.

 

Your script works great, thanks for posting it

 

Will this scirpt work correctly with 5.1.4 ??

 

WORKS great!

 

Does PHP4 need to be a module (and not CGI) for this script to work?

 

how can i apply (step by step) that script?

Thanks

 

Will this work with phpsuexec enabled? Also, anyway to do mysql 4x an 5x together?

 

Works with apache 1.3 ?

 

Same questions as everyone else.

1)- Can PHP4 already be installed as an apache module and still use this (PHP5 in CGI/PHP4 in Apache)?

2)- Will this work with Apache 1.3?

3)- How do you install the script?

4)- Will this work with the latest version of PHP5 and PhpSuExec?


And, if I install this can I use Apache to parse the ".php" files as ".php5" files? That way PHP4 is the default install and users can add the config to their .htaccess files to use hardcoded PHP5 scripts.

Ex: "xAddType x-mapp-php5 .php"

 

How do I do this? Can someone explain?
