php-fpm7.2 traphandle on Ubuntu doesn't work

[blindzero]

Main question

traphandle created by install script with php-fpm7.2 seems not to work

Purpose

I called the bin/installer script and this created a traphandle default /usr/sbin/php-fpm7.2 /usr/share/icingaweb2/modules/trapdirector/bin/trap_in.php

The PHP file path is correct, php-fpm7.2 is there. In syslog I always see

Apr 13 20:21:41 icinga2 snmptrapd[1023]: Usage: php-fpm7.2 [-n] [-e] [-h] [-i] [-m] [-v] [-t] [-p <prefix>] [-g <pid>] [-c <file>] [-d foo[=bar]] [-y <file>] [-D] [-F [-O]]

Hi,

Thanks for the feedback. The install script gets the php binary from the web server, and in this case you use php-fpm. This is OK for web server but you need the php binary to execute a php file in command line.

1) Find your php binary : must be /usr/bin/php

2) Replace in snmptrapd.conf :

traphandle default /usr/sbin/php-fpm7.2 /usr/share/icingaweb2/modules/trapdirector/bin/trap_in.php

by traphandle default /usr/bin/php /usr/share/icingaweb2/modules/trapdirector/bin/trap_in.php

(if your php binary is /usr/bin/php)

I'll make some more tests in the install script generator on the web page to avoid this problem and also update the docs.

@patrickpr Doh! Yeah...as more an infrastructure guy I am just too far away from that web stuff ;) Solved it perfectly. Would be great if installer could avoid it.

Thanks, M.
