[solved] Php-fpm status page won't load

[dkebler (David Kebler)]

Trying to get the php-fpm status per the www.conf file in 7.2

This posted helped but still not succeeding

Enable php-fpm status page

I have been using caddy for some months on a couple of low traffic sites to try it out and had no problems I’ve noticed until today: I am now setting up a very simple web server which will only serve jpeg images. Images or metadata are requested in various ways which are handled by a simple PHP framework. As it is (apparently) simple I have assumed a fairly low-spec virtual server can handle it but it is running into problems with a test request for 150 images at once. However I tweak php-fpm,…

my www.conf file has
pm.status_path = /phpfpm

my caddy entry is

https://status.kebler.net {
        import wildcard_cert
        fastcgi /phpfpm /var/run/php/php7.2-fpm-status.sock php
        fastcgi / /var/run/php/php7.2-fpm.sock php
        root /mnt/data/webs/status
        }

caddy and fpm services are restarted (no errors)
All other php based websites on server working fine.

put
https://status.kebler.net/phpfpm?html&full in browser I get 404 not found.
put in
https://status.kebler.net I get my root custom status page I built in php (works fine)

First I see no
/var/run/php/php7.2-fpm-status.sock
when I uncomment the status_path in www.conf it that supposed to fire up a status socket? If so I don’t see one. Well I tried it with the -status removed and either way no go.

just for grins I put a little php in /mnt/data/webs/status/phpfpm and the browser shows this so I can only conclude that the fastcgi /phpfpm line is not working and just dropping through.

I can see the status via the commandline so it’s a caddy isssue me thinks.

sysadmin@nas:~$ SCRIPT_NAME=/phpfpm   SCRIPT_FILENAME=/phpfpm   REQUEST_METHOD=GET   cgi-fcgi -bind -connect /var/run/php/php7.2-fpm.sock

Any other thoughts/input?

First I see no
/var/run/php/php7.2-fpm-status.sock

No, that is not meant to fire up a socket on its own.

I’d be wary of copying parts from other people’s configuration without understanding why they did what they did. In this case, in the other thread the user added an extra process, specifically to listen on -status.sock:

@Alan_Bradshaw

Now I’ve made a dedicated php-fpm process just for the status page so that I can use its socket like this:

  # intercept request for status page
  fastcgi /serverstatus /var/run/php/php7.1-fpm-status.sock

Lastly, the problem really is just to do with the FastCGI variables. Usually for PHP we rely on the php preset which sets a few of them for us, but it only really works well on index and *.php file requests.

Since want to specifically send every request under a certain base path to fastcgi, we need to specify the script name, exactly like you did on the command line. This example Caddyfile works for me.

:2015 {
  fastcgi /status :9000 {
    env SCRIPT_NAME /status
  }
}

TADA

https://status.kebler.net {
        import wildcard_cert
        fastcgi /phpfpm /var/run/php/php7.2-fpm.sock {
        env SCRIPT_NAME /phpfpm
        }
        fastcgi / /var/run/php/php7.2-fpm.sock php
        root /mnt/data/webs/status
        }

Guess if I have looked the directive docs would have dawned on to set the env variable there once I learned how to do it in the cli. https://caddyserver.com/docs/fastcgi. Thx
