Caddy file_server gives 403 error (forbidden) if started with systemctl

1. Caddy version (caddy version):

v2.3.0 h1:fnrqJLa3G5vfxcxmOH/+kJOcunPLhSBnjgIvjXV/QTA=

2. How I run Caddy:

sudo systemctl start caddy

a. System environment:

Red Hat Enterprise Linux release 8.3 (Ootpa)

b. Command:

sudo systemctl start caddy

c. Service/unit/compose file:

systemd service configuration file /etc/systemd/system/caddy.service:

d. My complete Caddyfile or JSON config:

dandeliion.soton.ac.uk, 192.168.174.219 {

        file_server

        }

        reverse_proxy @paths 127.0.0.1:8000

        tls internal

        log {
                output file /tmp/caddy_access.log
                format single_field common_log
        }
}

3. The problem I’m having:

As you can see from Caddyfile, I set up a file server (for static files) and a reverse proxy (for django project). When I start Caddy using caddy start or even /usr/bin/caddy run --environ --config /etc/caddy/Caddyfile, it works great! I see my django webpages and static files in the web browser.

Now I want to start Caddy via systemd. I created caddy.service file (see above) and now starting Caddy with exactly the same Caddyfile using sudo systemctl start caddy. The service starts and becomes green (active). But the web browser now only shows django webpages without any static files. Caddy access log file shows 403 error code for all static files (see below).

4. Error messages and/or full log output:

What Caddy access log shows. Django pages have status 200, they were shown properly. But all static files give 403 error code:

152.78.118.247 - - [29/Jan/2021:13:38:18 +0000] "GET /queue/?page=8 HTTP/1.1" 200 26016

sudo journalctl -xe gives the following output:

5. What I already tried:

Of course I double checked the owners and permissions in /var/www folder. I even changed the owner/group for all files and directories to caddy:caddy:

$ ls -la /var/www/
total 8
drwxr-xr-x.  3 caddy caddy   33 Jan 27 23:57 .
drwxr-xr-x. 23 root  root  4096 Jan 27 23:31 ..
-rw-r--r--.  1 root  root     5 Jan 27 23:57 1.txt
drwxr-xr-x.  5 caddy caddy  199 Jan 27 23:58 static

and

$ ls -la /var/www/static
total 136
drwxr-xr-x.   5 caddy caddy   199 Jan 27 23:58 .
drwxr-xr-x.   3 caddy caddy    33 Jan 27 23:57 ..
-rw-r--r--.   1 caddy caddy     5 Jan 27 23:58 1.txt
drwxr-xr-x.   6 caddy caddy    51 Jan 27 23:34 admin
-rw-r--r--.   1 caddy caddy  1753 Jan 27 23:34 description.js
-rw-r--r--.   1 caddy caddy 19050 Jan 27 23:34 dl_logo.png
-rw-r--r--.   1 caddy caddy 26579 Jan 27 23:34 double_part_size_s.png
-rw-r--r--.   1 caddy caddy   630 Jan 27 23:34 favicon.png
drwxr-xr-x.   2 caddy caddy  4096 Jan 27 23:34 queue
drwxr-xr-x. 218 caddy caddy 12288 Jan 27 23:34 results
-rw-r--r--.   1 caddy caddy 45247 Jan 27 23:34 style.css

Here you can see file 1.txt created for testing purposes. But Caddy still doesn’t show it in the browser and returns 403 error (see Caddy access log above).

But everything works perfect when I do caddy start, it shows all in the browser, including 1.txt without any errors. Something doesn’t work when I start it as a service via systemctl.

6. Links to relevant resources:

N/A

Please add the following to the top of your Caddyfile and try again, then look at the logs:

{
	debug
}

It might reveal what’s going on.

Since you’re running on RHEL, might it be an SELinux issue?

Thank you very much for your suggestion. I added debugging to the top of my Caddyfile. Now sudo journalctl -xe gave me two more lines:

Jan 29 20:07:49 srv03119 caddy[64315]: {"level":"debug","ts":1611950869.6295247,"logger":"http","msg":"starting server loop","address":"[::]:80","http3":false,"tls":false}

I also commented out format single_field common_log from the Caddyfile to get more informative access log. This is what it says when I try to access 1.txt for example:

{"level":"error","ts":1611950979.6284096,"logger":"http.log.access.log0","msg":"handled request","request":{"remote_addr":"152.78.118.247:3422","proto":"HTTP/1.1","method":"GET","host":"dandeliion.soton.ac.uk","uri":"/static/1.txt","headers":{"Dnt":["1"],"Cache-Control":["max-age=0"],"Upgrade-Insecure-Requests":["1"],"User-Agent":["Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:84.0) Gecko/20100101 Firefox/84.0"],"Accept":["text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"],"Accept-Language":["en-GB,en;q=0.5"],"Accept-Encoding":["gzip, deflate, br"],"Connection":["keep-alive"]},"tls":{"resumed":false,"version":771,"cipher_suite":49196,"proto":"","proto_mutual":true,"server_name":""}},"common_log":"152.78.118.247 - - [29/Jan/2021:20:09:39 +0000] \"GET /static/1.txt HTTP/1.1\" 403 0","duration":0.000224193,"size":0,"status":403,"resp_headers":{"Server":["Caddy"]}}

Error 403. But 1.txt will be immediately shown in the browser without any errors if I start Caddy as /usr/bin/caddy run --environ --config /etc/caddy/Caddyfile manually from the command line. But exactly the same command doesn’t work if it is executed via systemctl. I still cannot figure out what can be the problem. Please let me know if you need any other information.

Yes, exactly!

I had to google what SELinux is. So I tried to query the SELinux status:

$ getenforce
Enforcing

It says I am currently in Enforcing mode. Changing this to permissive mode temporary solved the problem:

$ sudo setenforce 0
$ getenforce
Permissive

Now I can see all static files in the browser even without reloading Caddy, it just starts to work.
But this is a temporary solution, because after some time the system sets it back to Enforcing mode automatically, for security reasons I guess.
Any ideas what can I do in this case?

Unfortunately I don’t have much experience with SELinux, cause I use ubuntu/debian typically. I just know enough that it can be an issue sometimes.

Yes, same for me. Ok, at least now I know where to dig. I’ll try to switch the system to Permissive mode permanently, if this is safe enough. Perhaps, this topic may be closed.

@francislavoie Thank you very much and please feel free to edit the title of the topic (it may sound a bit awkward because English is not my first language) so other people could easily find it if they face a similar problem on RHEL.

Found a good solution I think. No need to switch SELinux to Permissive mode. The problem is that the root www folder and all files in it were labeled incorrectly, so SELinux blocked them.

According to this document,

Every process, file, directory, device on an SELinux system has a label. If these labels are wrong for some reason SELinux will not function properly.
If a file is mislabeled a confined application might not be allowed access to the mislabeled file.

In my case, all static files are in /var/www/static/. The following command fixes the labels (recursively for the whole directory):

sudo restorecon -r /var/www/static/

restorecon reads the SELinux data store to determine how files under /var/www/static/ should be labeled and then fixes them.

That’s it, Caddy now works for me and keeps working after reboot too.

Awesome, thanks so much for the solution, to help others!
