Deploying Jar on Linux-server with Nginx

19.01.2022 | 814 | SQL

Hosting java application as jar file and running on server behind nginx web server

We create a service:

nano /etc/systemd/system/demo.service  [Unit]  Description=Demo Java App After=syslog.target  After=network.target[Service]  User=username  Type=simple    [Service]  ExecStart=/usr/bin/java -jar /var/www/sitename.com/demo.jar  Restart=always  StandardOutput=syslog  StandardError=syslog  SyslogIdentifier=demo   [Install]  WantedBy=multi-user.target

Create a proxy web config for nginx:

nano /etc/nginx/sites-available/sitename.com.conf  server {    listen 80;    server_name sitename.com;    location / {            proxy_pass http://localhost:8080/;            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;            proxy_set_header X-Forwarded-Proto $scheme;            proxy_set_header X-Forwarded-Port $server_port;    } }

We turn on the created config:

ln -s /etc/nginx/sites-available/sitename.com.conf /etc/nginx/sites-enable/

Restart the web server to apply the config:

systemctl restart nginx

We start the jar service:

systemctl start demo
