update PHP-FPM config default templates etc in 123.09beta01

- Below updates are only for new 123.09beta01 installs so as to not overwrite customisations made by users. Existing users can manually edit global section of /usr/local/etc/php-fpm.conf, /usr/local/nginx/conf/php.conf and /usr/local/nginx/conf/default_phpupstream.conf and manually setup /usr/local/nginx/conf/phpfpmd/phpfpm_pool1_uds.conf file and then restart nginx and php-fpm
- Update template used for /usr/local/etc/php-fpm.conf to raise global php-fpm values for emergency_restart_threshold and process_control_timeout from 10 and 10s to 100 and 185s respectively. .

Code (Text):

emergency_restart_threshold = 100
emergency_restart_interval = 1m
process_control_timeout = 185s

- Update template used for /usr/local/nginx/conf/php.conf to raise fastcgi_connect_timeout, fastcgi_send_timeout and fastcgi_read_timeout value to 360 and disable via comment out with hash # in front of fastcgi_keep_conn directive to disable persistent php-fpm connections for less throughput but higher concurrent load handling

Code (Text):

#fastcgi_keep_conn on;
fastcgi_connect_timeout 360;
fastcgi_send_timeout 360;
fastcgi_read_timeout 360;

- Update template used for /usr/local/nginx/conf/default_phpupstream.conf default PHP-FPM upstream named dft_php. Set dftphp_zone buffer to 256K. Note keepalive doesn't take effect as fastcgi_keep_conn is now disabled/commented out by default

Updated /usr/local/nginx/conf/default_phpupstream.conf looks like this now

Code (Text):

upstream dft_php {
  zone dftphp_zone 256k;
  server 127.0.0.1:9000;
  keepalive 2;
}

- Add a PHP-FPM unix socket pool for /var/run/php-fpm/php-fpm-pool1-uds.sock that can be optionally used at /usr/local/nginx/conf/phpfpmd/phpfpm_pool1_uds.conf when in /usr/local/etc/php-fpm.conf you uncomment include like and remove semi-colon.

from

Code (Text):

;include=/usr/local/nginx/conf/phpfpmd/*.conf

to

Code (Text):

include=/usr/local/nginx/conf/phpfpmd/*.conf

Existing 123.09beta01 users will need to update via cmupdate command and then copy /usr/local/src/centminmod/config/nginx/phpfpmd/phpfpm_pool1_uds.conf to /usr/local/nginx/conf/phpfpmd/phpfpm_pool1_uds.conf and restart nginx and php-fpm services

Then you can update and switch from TCP to unix socket PHP-FPM by editing /usr/local/nginx/conf/default_phpupstream.conf to below

Code (Text):

upstream dft_php {
  zone dftphp_zone 256k;
  #server 127.0.0.1:9000;
  server unix:/var/run/php-fpm/php-fpm-pool1-uds.sock;
  keepalive 2;
}

It's recommended to use TCP by default instead of PHP-FPM unix socket where possible but you can experiment for yourself
