I am not a Developer so Please No Hate for fellow Human for asking this , I Was asked to setup :

An AWS-EC2 Instance of Ununtu 16.04
RDS With Default DB
LEMP Stack (Linux , Nginx , Magento , Php 7.0)

I followed : This Link

Now This Magento Site Was Developed in Apache2 Environment and Now We copied the files to /var/www/html , We almost solved all errors One by one , Except One.

Only Home Page Works , No other page will work it will give us 404 , Following are config files if helps :

Edit This is Update /etc/nginx/nginx.conf File`hint taken from answer and magento config :

server {
listen *:8080;
server_name http://my ec2 public DNS;
root /var/www/html/;

##
# redirect to www
##
#if ($host !~* ^www\.) {
#    rewrite ^(.*)$ http://www.$host$1 permanent;
#}

##
# dont log robots.txt requests
##
location /robots.txt {
    allow all;
    log_not_found off;
    access_log off;
}

## These locations would be hidden by .htaccess normally
location ^~ /app/                { deny all; }
location ^~ /includes/           { deny all; }
location ^~ /lib/                { deny all; }
location ^~ /media/downloadable/ { deny all; }
location ^~ /pkginfo/            { deny all; }
location ^~ /report/config.xml   { deny all; }
location ^~ /var/                { deny all; }
location /var/export/            { deny all; }
# deny htaccess files
location ~ /\. {
    deny  all;
    access_log off;
    log_not_found off;
}

# error pages
error_page                    /404.html;

= /404.html {
root /usr/share/nginx/html;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

location / {
    try_files /maintenance.html $uri $uri/ @handler; ## If missing pass the URI to Magento's front handler
    expires 30d; ## Assume all files are cachable
}
location @handler { ## Magento uses a common front handler
    rewrite / /index.php;
}
location ~ .php/ { ## Forward paths like /js/index.php/x.js to relevant handler
    rewrite ^(.*.php)/ $1 last;
}

##
# pass the PHP scripts to FastCGI server listening at unix:/tmp/php5-fpm.sock
##
location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass unix:/tmp/php5-fpm.sock;
    fastcgi_index  index.php;
    fastcgi_param  SERVER_PORT 80;
    fastcgi_param  HTTPS $fastcgi_https;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    fastcgi_param  MAGE_RUN_CODE default; ## Store code is defined in administration > Configuration > Manage Stores
    fastcgi_param  MAGE_RUN_TYPE store;
}


rewrite ^/minify/([0-9]+)(/.*.(js|css))$ /lib/minify/m.php?f=$2&d=$1 last;
rewrite ^/skin/m/([0-9]+)(/.*.(js|css))$ /lib/minify/m.php?f=$2&d=$1 last;

}

Now the file in /etc/nginx/sites-avilable/default is :

Default server configuration

listen 80 default_server;
listen [::]:80 default_server;

server_name my server publlic ip;

location / {
    # First attempt to serve request as file, then
    # as directory, then fall back to displaying a 404.
    try_files $uri $uri/ =404;
}

#
location ~ \.php$ {
    include snippets/fastcgi-php.conf;

    # With php7.0-cgi alone:

    # With php7.0-fpm:
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}

# deny access to .htaccess files, if Apache's document root

#
location ~ /\.ht {
    deny all;
}

}

Virtual Host configuration for example.com

server {
listen 80;
listen [::]:80;

server_name my server ip;

root /var/www/html;
index index.php index.html;

location / {
    try_files $uri $uri/ =404;
}

location ~ .php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}

location ~ /\.ht {

}

}

**Does Any One have any Idea why only home page opens ? Would Really Appreciate Help **
