Hey,
would you (and the maintainers) be OK with a change to the phpXX_fpm.rc
file that allows the use of multiple PHP-FPM master processes? Currently
that is not possible because the pexp line matches all master processes.
My process list looks like this:
php-fpm-8.4: master process (/etc/php-fpm.conf.d/yw_1000.conf)
php-fpm-8.4: master process (/etc/php-fpm.conf.d/yw_1001.conf)
php-fpm-8.4: master process (/etc/php-fpm.conf.d/yw_1002.conf)
php-fpm-8.4: master process (/etc/php-fpm.conf.d/yw_1003.conf)
php-fpm-8.4: master process (/etc/php-fpm.conf.d/yw_1004.conf)
...
Currently every one has it's own .rc script with a hand written pexp
line, but it would be cleaner if i could just
ln -s /etc/rc.d/phpXX_fpm /etc/rc.d/phpXX_fpm_yw_1000
ln -s /etc/rc.d/phpXX_fpm /etc/rc.d/phpXX_fpm_yw_1001
ln -s /etc/rc.d/phpXX_fpm /etc/rc.d/phpXX_fpm_yw_1002
ln -s /etc/rc.d/phpXX_fpm /etc/rc.d/phpXX_fpm_yw_1003
ln -s /etc/rc.d/phpXX_fpm /etc/rc.d/phpXX_fpm_yw_1004
rcctl set php_fpm_yw_1000 flags -y /etc/php-fpm.conf.d/yw_1000.conf
rcctl set php_fpm_yw_1001 flags -y /etc/php-fpm.conf.d/yw_1001.conf
rcctl set php_fpm_yw_1002 flags -y /etc/php-fpm.conf.d/yw_1002.conf
rcctl set php_fpm_yw_1003 flags -y /etc/php-fpm.conf.d/yw_1003.conf
rcctl set php_fpm_yw_1004 flags -y /etc/php-fpm.conf.d/yw_1004.conf
Would you be OK with such a change? Or do you want to keep it as it is?
A little bit of background on why having multiple master processes is a
good idea:
The most important part of a production level PHP hosting is the
opcache, without it websites can be quite slow. The opcache (including
JIT function/trace) share the memory between all pools. PHP limits the
size of the memory used to around 4GB, but if you get over 2GB PHP-FPM
gets very sluggish (on OpenBSD only). If your server has 200GB of
memory, the 4GB limit is kind of small. So i split the hostings into
multiple master processes and with a smaller amount of pools in them.
Another benefit is, that you can isolate them better and restart/reload
only the ones you actually need.
Thanks
