Can't bring php-pm to life in Symfony5 #502

Open Sauerbrei opened 4 years ago

Basically, I did these steps:

symfony new ppm-test cd ppm-test docker run -vpwd:/var/www -p 8080:80 phppm/nginx --static-directory=public/

Output:

Tried then to start the server via packages: composer require php-pm/php-pm-httpkernel composer require php-pm/php-pm vendor/bin/ppm start --app-env=dev --logging=0 --debug=1 --workers=8 --port 8099 --cgi-path=

(I have no clue why I have to add --cgi-path= in order to bypass an error) Output:

My goal is to run ppm and symfony via docker-compose. In first place I just want to get it work :D Help is very welcome :)

dave-redfern commented 4 years ago

@Sauerbrei the first error is because the Kernel cannot be located. This could be because you have not correctly mounted your current working directory to the Docker container; or depending on what you named the namespace in src/Kernel.php you may need to export the APP_KERNEL_NAMESPACE env var. The PHP-PM Symfony bootstrap will try both App\Kernel and AppKernel.

Re: cgi-path: you have to specify this as the PHP CGI bin file is not in a consistent location across OSs (macOS brew is: /usr/local/bin/php-cgi, Alpine is: /usr/bin/php-cgi7, CentOS is: /usr/bin/php-cgi etc etc). Depending on your OS you may have to install php-cgi explicitly as it is sometimes packaged separately.

acasademont commented 4 years ago

Hi @Sauerbrei any more info about this?

Sauerbrei commented 4 years ago

Hey @acasademont I tried what was written above but stumbled upon more errors. After considering the documentation twice and also now, I have had no progress, so I abandon my project with php-pm. Sorry for that.

acasademont commented 4 years ago

@Sauerbrei now the error seems more clear, by default php-pm searches for the main symfony kernel at \App\Kernel or \AppKernel. If you have a custom Kernel or in a different namespace you have the APP_KERNEL_NAMESPACE and APP_KERNEL_CLASS_NAME to fix it.

So where does your Kernel class live?

Sauerbrei commented 4 years ago

@acasademont ok, lets give it a last shot.

So, I am using the default symfony kernel, no changes within the symfony skeleton. My Symfony version is 5.1.2. That means my Kernel lives at App\Kernel. I already added to my .env 

APP_KERNEL_NAMESPACE=App\
APP_KERNEL_CLASS_NAME=Kernel
APP_ENV=dev
APP_SECRET=xxx

image

Now, the following happens:

$ docker run -v `pwd`:/var/www -p 8080:80 phppm/nginx --bootstrap=symfony --static-directory=public/

Thank you for your help :)

acasademont commented 4 years ago

If you're using the default kernel location in App\Kernel you should not need to use those env variables, those are only for non-standard Kernel locations/names.

Your repo is fine, very similar to our Symfony 5 project. I believe there must be a problem with the docker image and the folder structure & autoloading...could you try it without docker?

Sauerbrei commented 4 years ago

Hm, this is strange...

cd ppm-test
ppm start
> --- Worker 5505 stderr ---
> PCNTL is not enabled in the PHP installation at /usr/bin/php-cgi7.4. See: http://php.net/manual/en/pcntl.installation.php

$ php -m | grep pcntl
> pcntl
$ php-cgi7.4 -m | grep pcntl
> pcntl

What am I doing wrong?

Sauerbrei commented 4 years ago

Regarding this tutorial https://serverfault.com/questions/158113/installing-pcntl-module-for-php-without-recompiling

my php tells me, PCNTL is already loaded
