CentOS 7 Ngnix 403 Error

Ngnix reports error 403 when access all connects under a directory but works under a different direction named "images". Original I thought it is dir/file permission issue. It turns out it is the default selinux setting. A good read https://www.getpagespeed.com/server-setup/nginx/nginx-selinux-configuration.

Passing parameters into springboot application

• User OS env variable
• Use java -Dk1=v1 -Dk2=v2
• Program argument java -jar my.jar --k1=v1 --k2=v2
• Use an external application.properties file and pointing to it with export spring.config.location=/tmp/application.properties or passing it in with java parameter -Dspring.config.location=/tmp/application.properties
