Perl module logs located in wrong file

January 12, 2021 08:59AM
Hello !

Here is the output of nginx -V :

nginx version: nginx/1.19.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC)
built with OpenSSL 1.1.1g 21 Apr 2020

Here is my nginx.conf :

user w3user webgrp;
worker_processes 1;

load_module ./modules/ngx_http_headers_more_filter_module.so;
error_log /var/projects/instance/nginx_1.19/logs/error.log debug;

pid /var/projects/instance/nginx_1.19/run/nginx.pid;

events {
worker_connections 1024;

http {
include mime.types;
default_type application/octet-stream;
perl_modules /appli/projects/instance/nginx_1.19/conf/perl/modules/;
perl_modules ./modules/perl/;
perl_require test.pm;

#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 /var/projects/instance/nginx_1.19/logs/access.log;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;
proxy_cache_path //var/projects/instance/nginx_1.19/cache/ levels=1:2 keys_zone=instance_cache:10m max_size=10g inactive=60m use_temp_path=off;
include /appli/projects/instance/nginx_1.19/conf//instance.conf;


I am witnessing a weird behaviour.
All logs are well written down in /var/projects/instance/nginx_1.19/logs/error.log (as provided in nginx.conf) excepting logs from perl_module which are written in /opt/nginx/1.19.2/logs/error.log.

For example (when nginx failed to locate perl module)

$ cat /opt/nginx/1.19.2/logs/error.log
2021/01/12 10:28:27 [emerg] 48992#48992: require_pv("test.pm") failed: "Can't locate test.pm in @INC (@INC contains: /appli/projects/instance/nginx_1.19/perl/modules/ /opt/nginx/1.19.2/./modules/perl/ /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at (eval 1) line 1."

or when start up went fine :

$ cat /opt/nginx/1.19.2/logs/error.log
2021/01/12 11:40:55 [notice] 53486#53486: signal process started

In other hand, remaining logs can be found in /var/projects/instance/nginx_1.19/logs/error.log.
This behaviour does not reproduce when I start nginx without perl module directives.

Any ideas of what is going on here ?

Thank you !
