Hi Misc, I am working on the new installation of LibreNMS using Nginx as the server
# uname -a OpenBSD lnms.int.autonlab.org 6.0 GENERIC.MP#2 amd64 Installation went well gd yes mysql yes snmp yes mcrypt yes pear yes I followed pkg-readmes and mysql, php, and nginx are correctly configured and working in the INSECURE mode(no chroot). Please no remarks if you are not familiar with LibreNMS and the fact that it has to be run in the insecure mode. I followed readme file librenms-201607 everything formally went well (I chose Web-based installation) including connecting to MariaDB. I can log into LibreNMS and the dashboard is displayed OK. The problem occurs when I tried to preform any of the actions from the top menu including logout. I get 500 Internal Server Error It almost feels there is something wrong with paths to PHP scripts which are supposed to be executed by pressing those buttons. The only interesting thing I see in my log files is this # tail -20 php-fpm.log [13-Dec-2016 21:35:55] NOTICE: exiting, bye-bye!

This is my complete /etc/nginx/nginx.conf file # Take note of http://wiki.nginx.org/Pitfalls user www; worker_processes 4; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #error_log syslog:server=unix:/dev/log,severity=notice; pid logs/nginx.pid; worker_rlimit_nofile 1024; events { worker_connections 800; } http { include mime.types; default_type application/octet-stream; index index.php; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; #access_log syslog:server=unix:/dev/log,severity=notice main; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 650; #gzip on; server_tokens off; server { listen 192.168.6.251:80; server_name lnms.int.autonlab.org; root /var/www/librenms/html; index index.php #charset koi8-r; #access_log logs/host.access.log main; #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /var/www/htdocs; } location / { # try_files $uri $uri/ @librenms; try_files $uri $uri/ @lnms; } # pass the PHP scripts to FastCGI server listening on unix socket # location ~ \.php$ { try_files $uri $uri/ =404; # fastcgi_pass unix:run/php-fpm.sock; fastcgi_pass unix:/var/www/run/php-fpm.sock; fastcgi_index index.php; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; # fastcgi_param DOCUMENT_ROOT /var/www$document_root; # fastcgi_param SCRIPT_FILENAME /var/www$document_root$fastcgi_script_name; # fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_split_path_info ^(.+\.php)(/.+)$; include fastcgi_params; } location ~ /\.ht { deny all; } location @lnms { rewrite ^api/v0(.*)$ /api_v0.php/$1 last; rewrite ^(.+)$ /index.php/$1 last; } } } As you can see my nginx.conf file is not 100% the same as Stuard's example from readmes but with his example I could not connect to the server. I experimented with having @librenms inseted of @lnms but I got the same result. The one other thing I did different was my /var/www/librenms is owned by _librenms:_librenms. I have not changed the permission on any file. I tried this after originally trying with root ownership of all files. Could somebody with better knowledge of nginx, php-fpm give me some idea what am I doing wrong? I know that the error is very generic and hard to debug. Most Kind Regards, Predrag Punosevac
