Installation and Getting Started tutorials for Linux process management tool Supervisord

Supervisor is a process management tool, the official saying:

The purpose is to have a process that needs to run all the time, but this process can be interrupted for a variety of reasons. I want to be able to restart it automatically when the process is interrupted, and I need to use the supervisor

There are two main commands:

• Supervisord : Supervisor Server-side section, starting supervisor is running this command
• Supervisorctl: Launches the command-line window for supervisor.

Installation (CentOS):

Way One:

Yum-y Install Python-setuptoolseasy_install Supervisor

Way two:

If the easy_install is not good, download it from the official:

wget https://pypi.python.org/packages/source/s/supervisor/supervisor-3.1.3.tar.gz

Then install it through Python:

Tar zxf supervisor-3.1.3.tar.gzcd supervisorpython setup.py Install

After a successful installation, you can log in to the Python console and enter import supervisor to see if it will load successfully.

Build configuration file (supervisord.conf):

echo_supervisord_conf >/etc/supervisord.conf

To modify a configuration file:

The last increment in supervisord.conf (the expression comment behind the semicolon, can not be written):

[program:bandwidth]command=python26/usr/local/bin/bandwidth.sh; command to be executed WD] User=root;(d Efault is the current user, Required if root) autostart=true; start at supervisord start (default:true) autorestart=true, whether/when to restart (de fault:unexpected) startsecs=3; number of secs prog must stay running (def. 1) stderr_logfile=/tmp/bandwidth_err.log; redi RECT proc stderr to stdout (default false) Error output redirect Stdout_logfile=/tmp/bandwidth.log; stdout log path, none for none; Default AUTO, log output
