In this technical post we will review how we can deploy a Spring Boot application using reverse proxy in a Nginx server. Please read this previous Spring Boot Setup post before continue this this information. I am using Nginx server 1.15.5 in Ubuntu 18.10. First, let’s create a new file description service in: /etc/systemd/system/spring-boot-setup.service with this information:
[Unit]
Description=Spring Boot Setup
After=syslog.target
After=network.target[Service]
User=josdem
Type=simple
[Service]
ExecStart=/bin/java -jar /opt/springboot-setup-0.0.1-SNAPSHOT.jar
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=spring-boot-setup
[Install]
WantedBy=multi-user.target
Start this service
sudo systemctl start spring-boot-setup
Check if is active
sudo systemctl status spring-boot-setup
Next step is to create a reverse proxy configuration in: /etc/nginx/conf.d/spring-boot-setup.conf
server {
listen 80;
listen [::]:80;
server_name spring.josdem.io;
location / {
proxy_pass http://localhost:8080/;
}
}
Test this configuration
sudo nginx -t
Output
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
Now restart Nginx
sudo systemctl restart nginx
The application is now accessible. Navigate to the public domain address and the “Hello World!” message should appear.
