Cant Install nextcloud on nginx, I think its fastcgi related

hi,
I keep getting error as follows :

2019/07/04 12:48:49 [error] 9154#0: *2 open() “/var/www/html/50x.html” failed (2: No such file or directory), client: 127.0.0.1, server: _, request: “GET /nextcloud/ HTTP/1.1”, upstream: “fastcgi://unix:/run/php-fpm/www.sock”, host: “localhost”

I have selinux disabled temporarily .

My namei -lv output is as follows;

drwxrwxr-x root root /
drwxr-xr-x root root var
drwxr-xr-x root root www
drwxr-xr-x root root html
drwxrwxrwx nginx nginx nextcloud
-rwxrwxrwx nginx nginx index.php

Yes for now its very lax because I keep getting errors and I am trying to correct it

My nginx conf is as follows :

Hello,
Did you manage to solve your problem ?
You have to comment “server 127.0.0.1:9000” and uncomment “server unix:/var/run/php/php7.0-fpm.sock;” in the php_handler context.
But, I understand why unix socket works but I dont understand why localhost doesnt work. I’m trying to understand and there is nothing in the nextcloud doc…

I think I understand. I dont know why the official documentation doesnt mentioned that but you can use unix socket or TCP socket. It hard to find doc about this, I found this on the net :


(I think you can just add “listen 127.0.0.1:9000” in the www.conf without removing “listen unix_socket…”, it works fine)

TCP socket is useful if your NextCloud is set up on several machines. But if php and NextCloud are on the same machine, its better to use unix socket.
