Description
In src/core/nginx.c, in ngx_cdecl(), the commandline parameters are first checked by calling nginx_get_options(), but then ngx_log_init() is called before actually processing the cmdline options later on, by calling ngx_process_options().
This means the ngx_log_init() will always run with the default compile-time error_log location. This is easily reproducable by creating a simple custom config file like:
error_log error_log.txt;
worker_processes 1;
pid nginx.pid;
events {
worker_connections 10;
}
http {
default_type text/plain;
server {
listen 127.0.0.1:8880;
access_log access.log;
}
}
then run that as any user that does not have write access to the default error log file:
$ nginx -c test.conf -p ~ nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)
Note that the configured error log file does get created and seems to be used, but the error message is still printed to stderr.

Yes, this is clearly a duplicate of #147.

Ah this is probably the same as https://trac.nginx.org/nginx/ticket/147
