PHP-FPM reload

[oerdnj]

Not sure which php version you are running, but since you are running on Ubuntu 14.04 you can uncomment the "reload" stanza in /etc/init/php5-fpm.conf, e.g. the file should look like this

# php5-fpm - The PHP FastCGI Process Manager

description "The PHP FastCGI Process Manager"
author "Ondřej Surý <[email protected]>"

start on runlevel [2345]
stop on runlevel [016]

reload signal USR2

pre-start exec /usr/lib/php5/php5-fpm-checkconf

respawn
exec /usr/sbin/php5-fpm --nodaemonize --fpm-config /etc/php5/fpm/php-fpm.conf

There's a compatibility problem with older upstart (unknown directives causes upstart to barf), so it's commented out by default.

I'll let this open and think about a better way how to detect correct upstart version and uncomment this by default.

I'm using latest version of PHP 5.5. However I really need reload since I don't want to kill current php processes that are running when new version of app is deployed.

[majksner]

I did uncomment of that line. Now it throws:

reload: Unknown instance:

[oerdnj]

Could you restart the service before reloading it?

[majksner]

Output:

root@ip:~# service php5-fpm restart
stop: Unknown instance:
php5-fpm start/running, process 29819
root@ip:~# service php5-fpm reload
reload: Unknown instance:

It seems there's some error in upstart :(.

Try stopping the service, then killing all remaining php5-fpm processes and then start it again...

Seems like that might help:

I see they have it reported https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1242376

But cannot believe that this is opened for 9 months and no fix.

[oerdnj]

It's not that easy to fix, since you need to care about upgrades from previous versions and that's when it breaks.

Fortunately I don't have to care about that - so I have prepared fix for the reload on upstart 1.10+

[majksner]

Any idea when new version of upstart will be released?

[oerdnj]

The 14.04 already has a upstart 1.12.1, but the problem is:

1. you start upgrading from Ubuntu 12.04 LTS that has upstart 1.5
2. you upgrade to php5-fpm with 'reload' command
3. the upgrade breaks since the postinst scripts barfs on 'reload' command that upstart 1.5 doesn't know about

The solution would be:

1. Install new upstart from Ubuntu 14.04
2. Reboot server
3. Install everything else

And you can see that's not going to fly... You want an upgrade to finish in one run.

[majksner]

I have freshly installed 14.04 on AWS and this is happending, I didn't upgrade from 12.04.

[oerdnj]

I understand, but your problem could be easily solved by uncommenting the 'reload' line in /etc/init/php5-fpm.conf.

The upgrade problem (that is different from yours) cannot be solved that easily. Thus they are not going to fix the problem in official Ubuntu packages.

[majksner]

I did uncomment that line, but still it doesn't work.

php5/5.5.14-2~+1 should be available from ppa:ondrej/php5 now with a patched FPM that accepts SIGHUP.

[majksner]

Thanks!
