Here are steps I followed on centos.

Step 1 (Optional): Set port

By default spring boot app run on port 8080, if you wish to change this you can change on your src/main/resources/application.properties file

server.port = 8082 // any port above than 1024

Step 2: Install apache if not installed already

On Centos 7

sudo yum install httpd

Step 3: Edit your virtual host

/etc/httpd/conf.d/vhost.conf

Your config should look like this

   ServerName yourdomin.com
   #DocumentRoot /var/www/html

   ProxyPreserveHost On
   ProxyPass / http://localhost:8082/
   ProxyPassReverse / http://localhost:8082/

And restart apache

sudo service httpd restart
