php7.0 + nginx makes 404 page error - nginx

Question

In AWS EC2 Instance, I make web environment using php7.0 and nginx.
And this makes 404 page error.
HTML Extension page is work well, but not on php.
in default.conf
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/log/host.access.log main;
location / {
root /var/www;
index index.php index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/error;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /var/www;
fastcgi_intercept_errors on;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
in fastcgi_params
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REQUEST_SCHEME $scheme;
fastcgi_param HTTPS $https if_not_empty;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
and in nginx.conf
user www-data;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
Whole environment is Nginx + php7.0 + mariaDB on AWS EC2 Instance.
I can't find what is wrong...

Answer 1

I will post this as an answer, but I am unfamiliar with php7 and AWS EC2.
You seem to have an inconsistency in your nginx configuration.
This block:
location / {
root /var/www;
index index.php index.html index.htm;
}
tells nginx that your files are located below /var/www, so that, for example:
the URI /index.html can be found at /var/www/index.html
the URI /foo/bar.html can be found at /var/www/foo/bar.html
The index directive tells nginx to look for index.php (etc.), also below /var/www. However, any URI ending with .php is processed by a different location block.
The block:
location ~ \.php$ {
root /var/www;
fastcgi_intercept_errors on;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
is intended to process .php URIs. Now, unless your architecture is special, the SCRIPT_FILENAME parameter passes the location of the file from nginx to the php subsystem. And on most systems, the value of $document_root$fastcgi_script_name is used which means that:
the URI /index.php can be found at /var/www/index.php
the URI /foo/bar.php can be found at /var/www/foo/bar.php
Assuming that root is set to /var/www.
In your configuration file, you are setting root in the location ~ \.php$ block but not using it. The root directive sets the value of $document_root.
There are other issues, but the important one is that (unless you are using a special architecture) the value of SCRIPT_FILENAME should be:
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
You should place include fastcgi_params; before any fastcgi_param directive to avoid the included file silently overwriting the desired value.
