Luci and nginx php co-exist

msnews · April 9, 2023, 11:58pm

Hi,

I am trying to use nginx with nextclould. I installed nginx-all-modules and nginx-ssl. I could not get uci to work with nginx so I disabled uci for nginx.
I created nginx.conf in /etc/nginx and luci.conf/luci.locations, nextcloud.conf in /etc/nginx/conf.d/.

The problem is if I have only nextcloud.conf in conf.d directory, I can open https://192.168.1.1/nextcloud/index.php. However, once I put luci.conf together, I can only open https://192.168.1.1 for luci. Nextcloud webpage is unable to open(404).

I attached all configuration below. How to make https://192.168.1.1/ opens luci and https://192.168.1.1/nextcloud opens nextcloud?

/etc/config/nginx:

config main global
	option uci_enable 'false'

config server '_lan'
	list listen '443 ssl default_server'
	list listen '[::]:443 ssl default_server'
	option server_name '_lan'
	list include 'restrict_locally'
	list include 'conf.d/*.locations'
	option uci_manage_ssl 'self-signed'
	option ssl_certificate '/etc/nginx/conf.d/_lan.crt'
	option ssl_certificate_key '/etc/nginx/conf.d/_lan.key'
	option ssl_session_cache 'shared:SSL:32k'
	option ssl_session_timeout '64m'
	option access_log 'off; # logd openwrt'

config server '_redirect2ssl'
	list listen '80'
	list listen '[::]:80'
	option server_name '_redirect2ssl'
	option return '302 https://$host$request_uri'

/etc/nginx/nginx.conf:

}

/etc/nginx/conf.d/luci.conf:

}

The problem is if I have only nextcloud.conf in conf.d directory, I can open https://192.168.1.1/nextcloud/index.php. However, once I put luci.conf together, I can only open https://192.168.1.1 for luci. Nextcloud webpage is unable to open(404).

From what i see once you put evrithing thogheter to acsess your nextcloud you need to visit cloud.example.com

Becuse, when Nginx receives a request, it looks for the best matching server block to handle the request based on the server_name directive and the URI.

Also why use https on a local network, do you have any specific reasson for that?

mmstano · April 10, 2023, 1:27am

While https may be overkill, it’s a means to harden security. Https prevents people on a local network from snooping packets in an attempt to get their password. Whatever the OP’s use-case is for it, idk, but it’s never a bad idea to make luci accessible via https only, even with a self-signed cert.

I don't have special purpose for using http or https. However I plan to use https for nextcloud for external access in the future. I have tried several ways but no success:

tried to comment out the server name.
use cloud.example.com/nextcloud/index.php.

I am not sure what is wrong with this configuration.

If that cannot be solved, I may separate http and https i.e. use http for luci and https for nextcloud
