Installation and configuration of Supervisor process monitoring and management tools under Mac _python

Supervisor is a process monitoring and management tool under a UNIX-like operating system.

Install Supervisor

Supervisor is written in Python and can be installed directly using Python's Package Installation management tool PIP (Python Package Index):

Copy Code code as follows:

sudo pip install Supervisor

Configure Supervisor

The Supervisor configuration file is named Supervisord.conf, which provides configuration option settings for Supervisord (Supervisor Primary Service command) and SUPERVISORCTL (Supervisor's monitoring Management command). Supervisor does not specify where the configuration file supervisord.conf is located, and the Supervisor service is started by default at:

Copy Code code as follows:

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

These directory locations look for profile supervisord.conf. Supervisor also provides the parameter "-C" to specify the directory path of the configuration file.

Enter the "echo_supervisord_conf" command at the terminal to view the contents of the default configuration of the supervisor.

To generate a default profile:

Copy Code code as follows:

echo_supervisord_conf >/etc/supervisord.conf

Here are the selected settings for some configuration, basically enough, configured as follows:

Copy Code code as follows:

[Inet_http_server]
Port = 127.0.0.1:9001
Username = DHQ
Password = 123456

[Unix_http_server]
File =/tmp/supervisor.sock
chmod = 0700

[Supervisord]
LogFile =/users/dengjoe/.supervisor/supervisord.log
Logfile_maxbytes = 50MB
logfile_backups=10
LogLevel = info
Pidfile =/tmp/supervisord.pid
Nodaemon = False
Minfds = 1024
Minprocs = 200
Umask = 022
Identifier = Supervisor
Directory =/tmp
Nocleanup = True
Childlogdir =/tmp

[Supervisorctl]
ServerURL = Unix:///tmp/supervisor.sock

[Rpcinterface:supervisor]
Supervisor.rpcinterface_factory = Supervisor.rpcinterface:make_main_rpcinterface



[Program:shadowsocks]
Directory =/users/dengjoe/shadowsocks
Command =/usr/bin/python/users/dengjoe/shadowsocks/local.py
Autostart = True
AutoRestart = True

Start Supervisor

Copy Code code as follows:

Supervisord-c/etc/supervisord.conf

The parameter "-C" indicates the path to the specified supervisor configuration file

Add Supervisord to the system boot service

Copy Code code as follows:

<?xml version= "1.0" encoding= "UTF-8"?>
<! DOCTYPE plist Public "-//apple//dtd plist 1.0//en" "Http://www.apple.com/DTDs/PropertyList-1.0.dtd" >

<string>-n</string>
<string>-c</string>
<string>/etc/supervisord.conf</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>

Start the Supervisor service:

Copy Code code as follows:

Launchctl Load ~/library/launchagents/dengjoe.supervisord.plist

Supervisorctl Monitoring Command

Supervisorctl is supervisor's own background Process Control tool, and the following are some of the uses of this command:

Start Application:

Copy Code code as follows:

Supervisorctl Start Program

Re-read configuration:
