systemctl start shiny-server
systemctl enable shiny-server

shiny-server has default index webpage by using 3838 port, you can enable 3838 port
by using firewall-cmd as follows:
1

firewall-cmd --permanent --zone=public --add-port=3838/tcp
firewall-cmd --reload
Alternatively, you can enable it on the console provided by the cloud server.
Run shiny app
Finally, assuming you have an R script app.Rin current directory , then run the code:
1
R -e "shiny::runApp('app.R',port=3737,host='0.0.0.0')"
Notice:host='0.0.0.0' should be added, or you can not access the shiny app from the internet. It means the Shiny app will accept connections on all network interfaces of the machine, making it accessible from any IP address that can reach your server.
