Nginx gives an Internal Server Error 500 after I have configured basic auth

Question

I am trying to do basic auth on Nginx. I have version 1.9.3 up and running on Ubuntu 14.04 and it works fine with a simple html file.

Here is the html file:

Answer 1

I was running Nginx in a Docker environment and I had the same issue. The reason was that some of the passwords were generated using bcrypt. I resolved it by using nginx:alpine.

Answer 2

Do you want a MORE secure password hash with nginx basic_auth? Do this:

echo "username:"$(mkpasswd -m sha-512) >> .htpasswd

SHA-512 is not considered nearly as good as bcrypt, but it's the best nginx supports at the moment.

Answer 3

In my case, I was using plain text password by -p flag, and coincidentally my password start with $ character. So I updated my password and thus the error was gone.

NB: Other people answer helped me a lot to figure out my problem. I am posting my solution here if anyone stuck in a rare case like me.

Answer 4

Well, just use correct RFC 2307 syntax:

passwordvalue          = schemeprefix encryptedpassword
schemeprefix           = "{" scheme "}"
scheme                 = "crypt" / "md5" / "sha" / altscheme
altscheme              = "x-" keystring
encryptedpassword      = encrypted password

For example: sha1 for helloworld for admin will be * admin:{SHA}at+xg6SiyUovktq1redipHiJpaE=

I had same error cause i wrote {SHA1} what against RFC syntax. When i fixed it - all worked like a charm. {sha} will not work too. Only correct {SHA}.

Answer 5

I just had the same problem - after checking log as suggested by @Drazen Urch I've discovered that the file had root:root permissions - after changing to forge:forge (I'm using Forge with Digital Ocean) - the problem went away.
