Topic: PHP as FCGID w/multiple PHP.INI files

[Brian]

First off, I did try to search AL for this topic, without success.

I have researched to the best of my current abilities to answer this without success.

Currently FCGID resolves the issue of stability having to call numerous non-thread-safe EXE's via PHP's EXEC() and SYSTEM() commands.

I have about 400 vhosts. I want to have at least two different PHP.INI files, at least two but maybe more.

The services I offer use a web-based file management, customized mail services, online image manipulation services, online media conversion services and so on. These all use a huge number of command line capable apps to make this all happen in this manner and PHP is so darn easy to code and secure, I just hate think that I have to go down a different path, starting over.

I could run some users, the bulk of my VHOSTS with the PHP module, but then I am running a more complicated environment than I would like to. If that is the only option for having multiple INI files, then so be it.

My Questions: Is it possible in WAMP to run PHP exclusively as FCGID and have different PHP.INI files?

If so, how?

php.example.com uses mod_php and it's one php.ini file
user1.example.com uses mod_fcgid and loads only the php.ini file in /home/user1
user2.example.com uses mod_fcgid and loads only the php.ini file in /home/user2
user3.example.com uses mod_fcgid but loads mod_php's php.ini file

Many thanks for this incredibly simple explanation.

Checked the test INI files, perfect.

Currently I am in test flight, but this solution looks promising.

Question: Do you notice any change in memory usage?

Even if the processing load creates more load, even if it were to and if it were to use more RAM, so what! This should be rock solid stable.

Thank you very much for your fast reply.

Hi Brian,
there no more usage with using different ini files as I know from my experience. At least if you don't load a different number of extensions. You should also be able to load different php version. Sometimes very useful for testing.

[Brian]

Different PHP versions, actually that can be important.

I have one extension that I use with ImageMagick, it requires a 4.x.x version of PHP but does somethings that I need very nicely.

I will probably end up running PHP as CGI and Module after all.

FCGID has really come a long ways with regards for PHP support and on Windows it really was needed.

I am running a full testing server on my workstation and so far I am very happy.

I have not had a chance to set up MySQL and also MSSQL yet. I also have an application for using an ODBC connection (SQLite3?) to pull data to generate reports from a Spiceworks db file. I used SQLite3 to pull live data into Excel so I assume that is the same connector PHP would use, not sure yet though.

I really appreciate AL and the many experienced contributors here, my simple question was thoroughly and quickly answered. Thank you.

Is this correct?

<VirtualHost *:80>
ServerName php.example.com
DocumentRoot "/home/htdocs"
</VirtualHost>

Shouldn't the line:

Hi,

I know that this thread is old, nevertheless, since we talk about Wampserver and that it is there, with the help of glasmith - thanks to him - that I found how to do it, I post here :
How to use fcgid_module and have different PHP versions for VirtualHost
- Procedure done under Wampserver 3.2.7 with Apache 2.4.52
To be done with Wampserver not started.

- 1 - Of course, the first thing to do is to download fcgid_module from the Apache Lounge download page depending on whether you use 32 or 64 bit Wampserver.
Unzip the related zip file and copy the 'mod_fcgid.so' file to the wamp(64)\bin\apache2.4.52\modules\ folder

- 2 - Edit the file wamp(64)\bin\apache2.4.52\conf\httpd.conf
Under the line: LoadModule php_module "${INSTALL_DIR}/bin/php/php.... (About line 199)
Be careful, it can be php7_module or php5_module depending on the php version used.

Thanks for sharing.

Hi,

Here I am now and it seems to work correctly while keeping PHP as an Apache module that coexists with fcgid_module.

In the file httpd.conf:

[James Blond]

You are doing it right with the fcgid config inside the directory.

On the other hand, I use "directory junctions" like a directory symlink on Linux. In that case, the config from the vhost is enough.

I wonder why you don't run fcgid only, but the module, too.

Hi,

I edit my previous post:

Hi,

If we use FcgidInitialEnv for the aliases, this raises the problem of remembering this first FCGI environment for the other aliases.
After reading the FCGI documentation very carefully, this is explained by :
Environment variables can also be set with FcgidInitialEnv, but they then apply to all applications.
and
Certain settings or other concepts that depend on the virtual host, such as FcgidInitialEnv or process classes, distinguish between virtual hosts only if they have distinct server names. (See the ServerName documentation for more information.) In the case of FcgidInitialEnv, if two virtual hosts have the same server name but different environments as defined by FcgidInitialEnv, the environment used for a particular request will be that defined for the virtual host of the request that caused the FastCGI process to be started.

By the way, in my case, alias have the same ServerName : localhost. This can be seen with phpinfo().

After a lot of testing and checking, for the aliases, we will replace FcgidInitialEnv with:

I just know that with Alias, follow with FcgidCmdOptions, and <Directory...> can make PHP run different version per folder.

Wonderful! Thanks a lot.

Here is my config in case who is looking fore more example.
