Installation and configuration of the Supervisor process monitoring and management tool on Mac

This article mainly introduces the installation and configuration of the Supervisor process monitoring management tool in Mac. the Supervisor is written in Python and is a process monitoring management tool in unix-like operating systems, this article describes the configuration and installation of MAC systems. For more information about how to use the Supervisor as a process monitoring and management tool for unix-like operating systems, see.

Install Supervisor

The Supervisor is written in Python and can be directly installed using the Python Package installation management tool pip (Python Package Index:

The code is as follows:

Sudo pip install supervisor

Configure a Supervisor

The configuration file of the Supervisor is named supervisord. conf, which provides configuration option settings for supervisord (the main service command of the Supervisor) and supervisorctl (the monitoring and management command of the Supervisor. The Supervisor does not specify the storage location of the configuration file supervisord. conf. by default, when the Supervisor service is started:

The code is as follows:

$ CWD/supervisord. conf
$ CWD/etc/supervisord. conf
/Etc/supervisord. conf

Find the configuration file supervisord. conf in these directories. The Supervisor also provides the "-c" parameter to specify the directory path of the configuration file.

Enter the "echo_supervisord_conf" command on the terminal to view the default configurations of the Supervisor.

Generate a default configuration file:

The code is as follows:

Echo_supervisord_conf>/etc/supervisord. conf

Some configurations are selected here, which are adequate. the configuration is as follows:

The code is as follows:

Start Supervisor

The code is as follows:

Supervisord-c/etc/supervisord. conf

The "-c" parameter specifies the path of the Supervisor configuration file.
