Hello all

First time here and need some help with the php-fpm.log file. Is there
a way to rotate the log on an hourly basis?

Background: I've been noticing that the the log file grows *very*
quickly. It reaches a file size of 2147483647 (2.0GB according to ls -
lFah) and then it's matter of time before php-fpm crashes. If I mv the
log file to something else and create a new log file, on reboot
everything works fine. If I don't do this manual log rotation, php-fpm
just doesn't start and fails to restart.

So how can I rotate the logs at high frequency?

Thanks,
Pierre

Hi Pierre,
You could do it a couple ways. To rotate the log file, you would just need
to move the current log file and then issue a SIGUSR1 to the php-fpm
process.

i.e.

mv /opt/php/logs/php-fpm.log /opt/php/logs/php-fpm.log.1
kill -SIGUSR1 `cat /opt/php/logs/php-fpm.pid`

Obviously replacing the paths to wherever your pid and log files are :)

Also you could use logrotate but I think this usually runs once per day, not
positive on that. Then logrotate would keep 3 logs and rotate only if size
is over 100MB.

Here is a sample logrotate that you would put into /etc/logrotate.d/php-fpm

/opt/php/logs/php-fpm*log {
size=100M
rotate 3
missingok
notifempty
sharedscripts
postrotate
kill -USR1 `cat /opt/php/logs/nginx.pid`
endscript
}

Hope that helps!

Davy

Accidentally said nginx.pid instead of php-fpm.pid
/opt/php/logs/php-fpm*log {
size=100M
rotate 3
missingok
notifempty
sharedscripts
postrotate
kill -USR1 `cat /opt/php/logs/*php-fpm.pid*`
endscript
}

Thanks, Davy.

Is there a way to rename with a serial number, like a timestamp
instead of just .1?

A simple shell script like this ought to do it:

[code]
#!/bin/bash
cd /usr/local/logs
stamp="$(date +%s)"
mv php-fpm.log php-fpm.log.$stamp
kill -SIGUSR1 `cat php-fpm.pid`
#gzip or delete or process however you like
gzip php-fpm.log.$stamp
exit
[/code]

Call it "rotate.sh" or whatever you like, make it executable, and run it as a cron every hour or however often you like. Note my path to php-fpm logs and pid is /usr/local/logs/. You need to use whatever your path(s) are. This will stamp the file with unix time so a log file will look like "php-fpm.log.1245891191" or " php-fpm.log.1245891191.gz" if gzipped.

might as well use logrotate though.
copy nginx's almost identical :)

Most systems default to run logrotate once a day. He's looking for an
hourly solution. You can set logrotate to run hourly but that won't take
care of the timestamp in the file name which he wanted (unless there's a
setting for that in logrotate - I don't know, I never looked). Anyway,
it's a simple script. Feel free to use it or not. It took about two
minutes for me to write it.
