Question How to get munin working again after switch from Apache to nginx ?

[pec]

I recently switched from Apache to nginx (thanx to @UFHH01 ), details here https://talk.plesk.com/threads/seo-friendly-urls-after-switch-from-apache-to-nginx.342063.

Now my site works well. Unfortunately, I am not able to access the munin stats anymore, neither via default domain nor via IP of the server.
The XenForo software steps in and complains about a missing route to "/munin".

My vhost_nginx.conf of the default domain now looks like this, based on suggestion on https://www.scalescale.com/tips/nginx/monitor-nginx-munin/:

# munin configuration
location /munin {
    alias   /var/www/munin/;
    index  index.php index.html index.htm;
    location ~* \.(png|jpg|jpeg|gif|ico)$ {
    }
}

if (!-e $request_filename){
    rewrite ^(.*)$ /index.php break;
}

location /install/data/ {
    internal;
}
location /install/templates/ {
    internal;
}
location /(internal_data|library) {
    internal;
}

# Media: images, icons, video, audio, HTC
location ~* \.(?:jpg|jpeg|gif|png|ico|gz|svg|svgz|mp4|ogg|ogv|webm|htc|woff)$ {
    expires 1M;
    access_log off;
    add_header Cache-Control "public";
}

# CSS and Javascript
location ~* \.(?:css|js)$ {
    expires 1y;
    access_log off;
    add_header Cache-Control "public";
}

Did I miss something ?

Hi pec,

I personally don't know much about "munin", but due to the fact that you recently switched from apache to the combination nginx+apache, I assume, that munin has a configuration file, where you define the webserver ports. In general that would be ":80"/":443" for the apache - webserver, but after your switch, it is ":7080"/":7081" for apache and now ":80"/":443" for nginx.

It would as well help, if you provide informations, how you formerly installed munin and what operating system you use. In addition it could as well help, if you provide informations about your PHP - handler in use for your domain and last but not least, you should be aware, that log - files often help to investigate issues/errors/problems.


Apart from the above, pls. note that this forum is a "Plesk-related" - community and you are currently in the subforum "Plesk Onyx" - consider to post threads, which are not related to Plesk, in the subforum: => Home > Forum > General Discussion > Open Topics

Hi @UFHH01,

The munin config is quite simple, no ports to configure, only paths:

# The next three variables specifies where the location of the RRD
# databases, the HTML output, and the logs, severally.  They all
# must be writable by the user running munin-cron.
dbdir   /var/lib/munin
htmldir /var/www/munin
logdir  /var/log/munin
rundir  /var/run/munin

# a simple host tree
[MyServer]
    address 127.0.0.1

No errors in the munin log. Munin itself works as before, all html and png files are created/updated regularly.
It's only the access to the files, that's not working. Seems that the "way" to /var/www/munin/ is not found, although (IMO) correctly configured.

nginx log says:

xx.xxx.xxx.xxx - - [15/Mar/2017:08:27:24 +0100] "GET /munin/ HTTP/1.1" 404 11372 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36"

Server OS is Ubuntu 12.04.5 LTS‬, munin has been installed via apt, php version is 7.0.16.
Plesk is 17.0.17 Update #18.

This morning I saw that also the Plesk webstats are not working any longer
Using the link in plesk (https://www.domain.com/plesk-stat/webstat/) returns a 404, https://www.domain.com/plesk-stat/ a 403.

You're totally right, sorry. munin is (unfortunately) not part of plesk
But with the stats now also not working it's possibly general plesk issue and potentially posted in the right forum

Hi pec,

I'm not a moderator, pec, but you should never consider to mix issues in one thread - there is plenty of space here, to open a new thread for each issue.


You could try to use:

location ^~ /munin/ {
    alias   /var/www/munin/;
}

This morning I saw that also the Plesk webstats are not working any longer

Consider to post your corresponding configuration files, in order to get help with your investigations and don't forget, that log - files often help as well, to get to the root cause of an issue/error/problem.

HI @UFHH01
Thanks for your quick reply

I'm not a moderator, pec, but you should never consider to mix issues in one thread - there is plenty of space here, to open a new thread for each issue.

I wasn't sure if the issues with munin and with plesk stats do have the same root cause. That's why my last sentence in my previous post
But ok, I will open a new thread for the stats issue. Tomorrow This thread could be moved to the other forum by a moderator.

You could try to use:

location ^~ /munin/ {
    alias   /var/www/munin/;
}

​

Unfortunately, same result: 404
