I prepared settings for nginx

access_log /var/log/nginx/domain.name.access.log;
error_log /var/log/nginx/domain.name.error.log;

default_type "text/plain";
try_files $uri =404;
}

location / {
return 301 $host$request_uri; }
}
server {
listen 443 ssl http2;
server_name blog.datacoding.io;

I installed ghost using ghost-cli

ghost install --no-prompt --no-stack --no-start
--dir /opt/ghost --no-setup-linux-user --no-setup-nginx --no-setup-ssl --no-setup-systemd
--db sqlite3 --dbpath /opt/ghost/content/data/ghost.db
--ip 127.0.0.1 --port 2368 --url ghost.domain.name

and my production settings

"server": {
"port": 2368,
"host": "127.0.0.1"
},

},
"logging": {

},
