Nginx – restart php5-fpm from php script

nginxPHPphp-fpmservice

Ok, this is a tricky one (I think)
I need to reload php5-fpm from a php script
The obvious issue is that once the reload command is executed, the current script is disturbed,
I tried to delay the execution like so

(sleep 5;  sudo service php5-php reload) & echo ""

but this does not help,
the immediate nginx response is 502 bad gateway.
FYI, i'm using php's exec function

any way around this?

Make sure the user running php has the sudo privileges to reload php5-fpm, then:

shell_exec("nohup sh -c 'sleep 1; sudo reload php5-fpm' > /dev/null 2>&1 &");

I think your max_children is too low

<value name="max_children">3</value>

Also you can try switching from TCP port to unix socket for php-fpm:

php-fpm.conf

<value name="listen_address">/tmp/php.sock</value>

nginx.conf

fastcgi_pass unix:/tmp/php.sock;

Elaborated:

Unix sockets are ~20% faster
You don't use time-wait sockets for each connect

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart    # typical
/etc/init.d/php5-fpm restart   # debian-style
/etc/init.d/php7.0-fpm restart # debian-style PHP 7

Using service wrapper script

service php-fpm restart    # typical
service php5-fpm restart   # debian-style
service php7.0-fpm restart # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service    # typical
systemctl restart php5-fpm.service   # uncommon
systemctl restart php7.0-fpm.service # uncommon PHP 7

Or whatever the equivalent is on your system.
