Configuration and use of Supervisor

Environment: Ubuntu 14.04 LTS http://supervisord.org/
Liunx has a lot of daemon tools, such as Nohup,screen,supervisor, Supervisor is a process management program developed in Python, can be a normal command-line process into the background daemon, abnormal exit can be automatically restarted.
#安装
sudo apt-get install Supervisor
#进程
/usr/bin/supervisord--Supervisor Service Daemon
/usr/bin/supervisorctl--Supervisor Console process
In/etc/ The Supervisor directory contains the Supervisor configuration file: Where CONF.D is a subdirectory that holds configuration information for the supervisor supervised process, a process that has a corresponding configuration file supervisord.conf is the main configuration file for supervisor, Define the service name, interface, and so on.
#配置
Now to monitor a script process with supervisor, create a new configuration file for this script process in/ETC/SUPERVISOR/CONF.D [I deployed a Python and Golang Web program]
Cd/etc/supervisor/conf.d
Touch gogs.conf stock.conf

[Program:gogs]
command=/opt/gogs/scripts/start.sh
Directory=/opt/gogs
Autostart=true
Autorestart=true
Stdout_logfile=/var/log/supervisor/gogs_supervisor_out.log
Stderr_logfile=/var/log/supervisor/gogs__supervisor_err.log

[PROGRAM:STOCKHQ]
Command=python3 __stockhq.py
Directory=/opt/stockhq/data
Autostart=true
Autorestart=true
Startsecs=1
Stderr_logfile=/var/log/stockhq_err.log
Stdout_logfile=/var/log/stockhq_out.log

NETSTAT-NTPL (Port of TCP type)

sudo ps-ef | grep Supervisor
#杀死进程

Modifying the master configuration file
Vim/etc/supervisor/supervisord.conf, add the following:
[Inet_http_server]
Port = 0.0.0.0:9001 #ip and bound port
Username = Irving # administrator Name
Password = 123456 #管理员密码
In this way, enter the address and port number of the configuration in the browser, enter the configured user name and password, then you can see the Web-based console
Interface. From this, you can view the > information of Supervisor Monitoring, and can see the log of the process.

If the server has an extranet to access, configure your Web server to start listening 0.0.0.0 (not 127.0.01).
