Community Discussion: Default settings for PHP and Apache/Nginx

I would like to standardize sane default settings for PHP and Apache/Nginx across all of their versions.

Todo

Webserver

• timeout
• timeout to upstream PHP-FPM connection: 180sec
• body/post size

---

Done

PHP

Defaults for PHP are available here:

• https://github.com/devilbox/docker-php-fpm/blob/master/build/ansible/group_vars/all.yml#L26
• https://github.com/devilbox/docker-php-fpm/tree/master/build/ansible/CONFIGURATION

php-fpm.conf

[global]
log_level = notice

[www]
request_terminate_timeout = 120s
listen.backlog = 1024
pm = ondemand
pm.max_children = 50
pm.start_servers = 4
pm.min_spare_servers = 2
pm.max_spare_servers = 6
pm.max_requests = 500
pm.process_idle_timeout = 10s

php.ini

memory_limit		= 512M

max_execution_time      = 120
max_input_time          = 120

post_max_size           = 72M

max_file_uploads        = 20

variables_order         = EGPCS

for MySQL I have found these settings help:

max_allowed_packet=64M
tmpdir=/dev/shm

max_allowed_packet helps when importing dumps with long lines. It prevents the 'mysql has gone away' message.

For PHP

[PHP]
; Memory
memory_limit = 512M

; Timeouts
max_execution_time = 240
max_input_time = 240

; Uploads
post_max_size = 256M
upload_max_filesize = 256M

; Vars
max_input_vars = 8000

; Error reporting
display_errors = On
track_errors = On

; Opcache boost
opcache.max_accelerated_files = 10000
opcache.memory_consumption = 128
opcache.interned_strings_buffer = 16
opcache.validate_timestamps = 0

; Mailhog
sendmail_path = '/usr/local/bin/mhsendmail --smtp-addr="mailhog:1025"'

Hey! It would be awesome to create one config file (or maybe as a part of .env) for those general configurations (as upload_max_filesize) to share them automatically across versions depend on your configuration. That would help me a lot 👍 What do you think?

[cytopia]

@jukben those standard settings will be baked into each container by default, once they have been defined. So there will be no need for the user to apply standard settings, only to change those.

On the other hand, yep, that would definitely solve my problem why I had to mess with config in the first place #323 Thanks for working on this. 🙌

php.ini defaults

• PR: devilbox/docker-php-fpm#39
• Base image defaults: https://github.com/devilbox/docker-php-fpm/blob/1b6799da58dea474f5d20e111258c2b22524d842/build/ansible/CONFIGURATION/php-base.ini
• Prod image defaults: https://github.com/devilbox/docker-php-fpm/blob/1b6799da58dea474f5d20e111258c2b22524d842/build/ansible/CONFIGURATION/php-prod.ini
• Work image defaults: https://github.com/devilbox/docker-php-fpm/blob/1b6799da58dea474f5d20e111258c2b22524d842/build/ansible/CONFIGURATION/php-work.ini

How it works

1. Every flavour inherits from the its previous flavor (prod from base and work from prod).
2. Every flavour can overwrite previous flavour values (e.g. work overwrites base error_reporting settings)

Quick update: PHP defaults PR has been merged and new Images should be available in 1-2 hours.

@Tuurlijk I left out opcache settings at the moment as I am not very experienced with it.

[cytopia]

I am adding new PHP-FPM settings: devilbox/docker-php-fpm#40 to solve the following issue: #234

pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500

Update

The above settings not valid anymore

For new settings see initial post at the very top

Migration note

Community discussion will be continued on The Devilbox Forums in topic: Default settings for PHP-FPM
