Tutorial on upgrading, installing and configuring supervisor on centos6.5

Supervisor Introduction

Supervisor is a client/server service developed in Python. It is a process management tool for Linux/Unix systems and does not support Windows systems. It can easily monitor, start, stop, and restart one or more processes. When a process managed by Supervisor is killed accidentally, supervisor will automatically restart it after detecting the process death, which makes it very convenient to automatically restore the process without having to write shell scripts to control it.

Because I want to use it to manage multiple PHP processes to perform tasks, configuring multiple subprocesses in the default version does not work

The default version of Supervisor is 2.1.9, which seems to have problems running multiple subprocesses. The latest version of Supervisor 4.1 requires a higher version of Python, so the following solution is used:

Install pip first

yum install python-pip

Then use pip to install version 3.1 of supervisor

pip install supervisor==3.1.3

Generate configuration files

easy_install supervisor==3.1.3

Configuration Files

/etc/supervisord.conf

[program:php_imap_daishou]
command=/usr/bin/php /usr/local/sinamail/tools/new/othermail/cli.php entresign
process_name=%(program_name)s_%(process_num)02d
numprocs=10
user=root 

Summarize

The above is the tutorial on upgrading, installing and configuring Supervisor in CentOS 6.5 that I introduced to you. I hope it will be helpful to you!
