|

# | arg: -v, --phpversion= - Version of PHP to use.

|
||||
# | arg: -p, --package= - Additionnal PHP packages to install
|

# | arg: -d, --dedicated_service - Use a dedicated PHP-FPM service instead of the common one.
|
||||
# usage: ynh_add_fpm_config
|
||||
#
|
||||
# -----------------------------------------------------------------------------
|
||||
# Case 1 (recommended) : your provided a snippet conf/extra_php-fpm.conf
|
||||
#
|
||||
# usage 2: ynh_add_fpm_config [--phpversion=7.X] --usage=usage --footprint=footprint [--package=packages] [--dedicated_service]
|
||||
# | arg: -v, --phpversion= - Version of PHP to use.
|
||||
# | arg: -f, --footprint= - Memory footprint of the service (low/medium/high).
|
||||
# The actual PHP configuration will be automatically generated,
|
||||
# and your extra_php-fpm.conf will be appended (typically contains PHP upload limits)
|
||||
#
|
||||
# The resulting configuration will be deployed to the appropriate place, /etc/php/$phpversion/fpm/pool.d/$app.conf
|
||||
#
|
||||
# Performance-related options in the PHP conf, such as :
|
||||
# pm.max_children, pm.start_servers, pm.min_spare_servers pm.max_spare_servers
|
||||
# are computed from two parameters called "usage" and "footprint" which can be set to low/medium/high. (cf details below)
|
||||
#
|
||||
# If you wish to tweak those, please initialize the settings `fpm_usage` and `fpm_footprint`
|
||||
# *prior* to calling this helper. Otherwise, "low" will be used as a default for both values.
|
||||
#
|
||||
# Otherwise, if you want the user to have control over these, we encourage to create a config panel
|
||||
# (which should ultimately be standardized by the core ...)
|
||||
#
|
||||
# Case 2 (deprecate) : you provided an entire conf/php-fpm.conf
|
||||
#
|
||||
# The configuration will be hydrated, replacing __FOOBAR__ placeholders with $foobar values, etc.
|
||||
#
|
||||
# The resulting configuration will be deployed to the appropriate place, /etc/php/$phpversion/fpm/pool.d/$app.conf

# fpm_footprint: Memory footprint of the service (low/medium/high).
|
||||
# low - Less than 20 MB of RAM by pool.
|
||||
# medium - Between 20 MB and 40 MB of RAM by pool.
|
||||
# high - More than 40 MB of RAM by pool.
|

# Or specify exactly the footprint, the load of the service as MB by pool instead of having a standard value.
|
||||
# To have this value, use the following command and stress the service.
|
||||
# watch -n0.5 ps -o user,cmd,%cpu,rss -u APP
|

# N - Or you can specify a quantitative footprint as MB by pool (use watch -n0.5 ps -o user,cmd,%cpu,rss -u APP)
|
||||
#
|

# | arg: -u, --usage= - Expected usage of the service (low/medium/high).
|

# fpm_usage: Expected usage of the service (low/medium/high).
|
||||
# low - Personal usage, behind the SSO.
|
||||
# medium - Low usage, few people or/and publicly accessible.
|
||||
# high - High usage, frequently visited website.

|
||||
