Error setting up http authentication - 500 Internal Server Error

Server NGINX
1

I am using the instruction given at
http://wiki.codemongers.com/NginxHttpAuthBasicModule#auth_basic

When i access the site i get prompted for username and password.
After i enter the username and password i get the error “500 Internal
Server Error”

When i have the following two lines commented out i do not get any
error.

auth_basic “osusu”;

auth_basic_user_file conf/passwd;

What am i doing wrong?

Here is the setup of my conf file

upstream domain1 {
server 127.0.0.1:8000;
server 127.0.0.1:8001;
}

server {
listen 80;
server_name www.osusu.com;
rewrite ^/(.*) http://domain.com permanent;
}

server {
listen 80;
server_name osusu.com;

access_log /home/demo/public_html/domain.com/shared/log/access.log;
error_log /home/demo/public_html/domain.com/shared/log/error.log;

root /home/demo/public_html/domain.com/current/public/;
index index.html;

location / {
auth_basic “osusu”;
auth_basic_user_file conf/passwd;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect false;

if (-f $request_filename/index.html) {
rewrite (.) $1/index.html break;
}
if (-f $request_filename.html) {
rewrite (.) $1.html break;
}
if (!-f $request_filename) {
proxy_pass http://domain1;
break;
}
}
}

I created the conf file using the utility htpasswd.

Any help on this is greatly appretiated…

Hi

Here is the setup in the top level conf file

============================
user www-data;
worker_processes 1;

error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
}

http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

access_log  /var/log/nginx/access.log;
error_log   /var/log/nginx/error.log;

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;
tcp_nodelay        on;

gzip  on;

include /etc/nginx/sites-enabled/*;

}

Here are the messages from the error.log file in
/var/log/nginx/error.log

demo@Himalaya:/etc/nginx$ cat /var/log/nginx/error.log
2008/02/25 15:45:59 [error] 5813#0: *1 open()

error is not being written to the error.log file…

the permission for the error log file is set as below

demo@Himalaya:/etc/nginx/sites-available$ ls -al
/var/log/nginx/error.log
-rw-r–r-- 1 root root 416 Feb 25 15:55 /var/log/nginx/error.log

Here are the two process one is running as root and the second one as
www-data.
demo@Himalaya:/etc/nginx/sites-available$ ps aux | grep nginx
root 10159 0.0 0.3 27436 808 ? Ss 19:04 0:00
nginx: master process /usr/sbin/nginx
www-data 10160 0.0 0.5 27884 1564 ? S 19:04 0:00
nginx: worker process

the root as write permision so i am not sure why erorrs are not being
logged!!

There should be an error line at the same time when you tried to access
site.

Well, could yo build nginx with debug:

./configure --with-debug …

and enable debug log in nginx.conf:

error_log /var/log/nginx/error.log debug;

Then do failed request and show the log. Note, that user/password will
be plain text encoded in base64, so use dummy user name and password.

Hi,

I had the same problem just minutes ago.

I solved it by specifying the absolute path to the password file.

Mine is located at: /etc/nginx/htpasswd

So in my configuration file I had tto put:

auth_basic_user_file /etc/nginx/htpasswd;

If that helps you.

When i have the following two lines commented out i do not get any
error.

auth_basic “osusu”;

auth_basic_user_file conf/passwd;

In this case in error_log should be message:

… [crit] … open() “… /conf/passwd” failed (2: No such file or
directory), …

Yes that’s how I found out about it.
