6.1. Managing the Proxy Service
Since the RHN Proxy Server consists of a multitude of individual components, Red Hat
provides a master service,
rhn-proxy
, that allows you to stop, start, or retrieve status from
the various services in the appropriate order. This helper service accepts all of the typical
commands:
service rhn-proxy start
service rhn-proxy stop
service rhn-proxy restart
service rhn-proxy status
Use the
rhn-proxy
service to shut down and bring up the entire RHN Proxy Server and
retrieve status messages from all of its services at once.
6.2. Log Files
Virtually every troubleshooting step should start with a look at the associated log file or
files. These files provide invaluable information about the activity that has taken place on
the device or within the application and can be used to monitor performance and ensure
proper configuration. See Table 6-1 for the paths to all relevant log files:
