Simple supervisor teaching and supervisor Teaching

A supervisor can be used to protect processes running in linux and provide functions such as start, stop, and restart to prevent the processes from being killed by other processes by mistake.

• First, apt-get install supervisor
• Supervisord is the main program of daemon. It generates the default configuration file echo_supervisord_conf>/etc/supervisord. conf and serves supervisord-c/home/supervisord. conf.
• Open supervisorctl and find that no monitored service is available.
• Now write the Process configuration to be managed, similar to the following

• [Program: gftrader] command = python3/home/gftrader/runStrategy. pydirectory =/home/gftrader/autorestart = truelog_stdout = truelog_stderr = trueexitcodes = 0, 2 stopsignal = QUITstopwaitsecs = 10stdout_logfile =/tmp/gftrader. log

   

• Supervisorctl reread: click it, And then update it to view the status. help can look at other commands.
