Nginx Sub domain setup - nginx

Question

I'm trying to setup Nginx so I can have sub domains like
www.MySite.com - Main website (Works correctly)
jenkins.MySite.com - sub domain for Jenkins
gitlab.MySite.com - sub domain for Gitlab
I've tried following various tutorials and I seem to have included everything required to make this work, but still to no avail.
I've followed this: https://www.digitalocean.com/community/tutorials/how-to-configure-nginx-with-ssl-as-a-reverse-proxy-for-jenkins
and various other sources online.
[Nginx Server Block]
I've edited my nginx.conf file, I've created a new nginx/sites-available conf file for Jenkins and symlinked it to sites-enabled.
This is my default jenkins JENKINS_ARGS
JENKINS_ARGS="--webroot=/var/cache/jenkins/war --httpListenAddress=127.0.0.1 --httpPort=$HTTP_PORT -ajp13Port=$AJP_PORT"
This is an example of my jenkins server block in nginx
server
{
listen 80;
return 301 https://$host$request_uri;
}
server
{
listen 443;
server_name jenkins.MySite.com;
#ssl_certificate /etc/nginx/cert.crt;
#ssl_certificate_key /etc/nginx/cert.key;
#ssl on;
#ssl_session_cache builtin:1000 shared:SSL:10m;
#ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
#ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
#ssl_prefer_server_ciphers on;
access_log /var/log/nginx/jenkins/access.log;
location /
{
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
# Fix the “It appears that your reverse proxy set up is broken" error.
proxy_pass http://127.0.0.1:8080;
proxy_read_timeout 90;
proxy_redirect http://127.0.0.1:8080 https://jenkins.MySite.com;
}
}
I've also created an A record in DigitalOcean - Network
and also a CNAME
Much help would be appreciated.
Thanks

All these 3-setups need separate ngnix config files and supervirosor files as you did for main site. make soft link of those files and put them in respective etc/nginx/sites-avai and sites-enable and also soft link the supervisor files to etc/supervisor/conf.d
To check whether the nginx file is properly configured, you need to test it.
sudo nginx -t
