In CentOS 7.2, the official yum source of nginx was added. Use yum install nginx to install nginx/1.10.2
After the installation was completed, I turned off the system firewall and the default site could be accessed normally. I added another virtual Host configuration file, the content is as follows:

server { listen 80; server_name idas.it; root /home/html; index index.html index.php; # location / { # try_files $uri $uri/ /index.php?$query_string; # } location ~ \.php$ { fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }

Directory permissions are as follows:

[root@hrms /]# ll && cd /home && ll && cd html && ll total 84 dr-xr-xr-x. 17 root root 4096 Nov 12 13:39 . dr-xr-xr-x. 17 root root 4096 Nov 12 13:39 .. lrwxrwxrwx. 1 root root 7 Nov 12 11:37 bin -> usr/bin dr-xr-xr-x. 5 root root 4096 Nov 12 12:16 boot drwxr-xr-x. 20 root root 3260 Nov 12 13:10 dev drwxr-xr-x. 83 root root 8192 Nov 12 14:40 etc drwxr-xr-x. 5 root root 78 Nov 12 15:27 home lrwxrwxrwx. 1 root root 7 Nov 12 11:37 lib -> usr/lib lrwxrwxrwx. 1 root root 9 Nov 12 11:37 lib64 -> usr/lib64 drwxr-xr-x. 2 root root 6 Aug 12 2015 media drwxr-xr-x. 2 root root 6 Aug 12 2015 mnt drwxr-xr-x. 2 root root 6 Aug 12 2015 opt dr-xr-xr-x. 137 root root 0 Nov 12 13:10 proc -rw-r--r--. 1 root root 43092 Nov 12 13:11 .readahead dr-xr-x---. 6 root root 4096 Nov 12 15:23 root drwxr-xr-x. 24 root root 680 Nov 12 15:31 run lrwxrwxrwx. 1 root root 8 Nov 12 11:37 sbin -> usr/sbin drwxr-xr-x. 2 root root 6 Aug 12 2015 srv dr-xr-xr-x. 13 root root 0 Nov 12 13:10 sys drwxrwxrwt. 10 root root 4096 Nov 12 15:31 tmp drwxr-xr-x. 13 root root 4096 Nov 12 11:37 usr drwxr-xr-x. 20 root root 4096 Nov 12 13:38 var total 12 drwxr-xr-x. 5 root root 78 Nov 12 15:27 . dr-xr-xr-x. 17 root root 4096 Nov 12 13:39 .. -rw-r--r--. 1 root root 1097 Oct 19 00:35 default.conf drwxrwxr-x. 2 root root 23 Nov 12 15:24 html drwxr-xr-x. 5 mysql mysql 4096 Nov 12 14:22 mysql drwxrwxr-x. 2 nginx nginx 6 Nov 12 14:41 php total 4 drwxrwxr-x. 2 root root 23 Nov 12 15:24 . drwxr-xr-x. 5 root root 78 Nov 12 15:27 .. -rwxrwxr-x. 1 root root 612 Nov 12 15:24 index.html

The permissions are given, but the access is still 403 Forbidden. The following is the nginx error log:

2016/11/12 15:31:28 [error] 17524#17524: *2 "/home/html/index.html" is forbidden (13: Permission denied), client: 10.120.9.254, server: idas.it, request: "GET / HTTP/1.1", host: "idas.it" 2016/11/12 15:39:28 [error] 17524#17524: *3 "/home/html/index.html" is forbidden (13: Permission denied), client: 10.120.9.254, server: idas.it, request: "GET / HTTP/1.1", host: "idas.it" 2016/11/12 15:39:29 [error] 17524#17524: *3 "/home/html/index.html" is forbidden (13: Permission denied), client: 10.120.9.254, server: idas.it, request: "GET / HTTP/1.1", host: "idas.it"

With the same permission configuration, why can the /var/share/nginx/html directory be accessed normally, but other directories have no permissions?

[root@hrms html]# ps aux | grep nginx nginx 17292 0.0 0.1 650776 10504 ? S 14:50 0:00 php-fpm: pool www nginx 17293 0.0 0.1 650776 10500 ?

I later set the owner and user group of /home, subdirectories and files to nginx, but it still got 403 Forbidden and the error log was still the same!
