在与3838不同的端口上运行Shiny-server

# Define the port number that should be used for the Shiny applications
# listening connections. Shiny applications will be available at a URL
# like http://<hostname>:<port>/.
# In most cases the port number should be left unspecified and the server
# will automatically find an available port number. In some cases (e.g.
# multiple Shiny servers running in parallel on a single machine) it can
# be necessary to specify a port number.
