Supervisor: A Process Control System
说明：[http://supervisord.org/]Supervisor is a client/server system that allows its users to monitor and control a number of processes on UNIX-like operating systems.
Supervisor使用python开发的一个c/s服务，linux下进程管理系统、监听、重启、停止进程。Server supervisord，supervisorctl作为客户端管理进程。
一、 安装
1、yum 安装： yum install supervisor
2、easy_install 安装：wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O |python && easy_install supervisor
3、salt stack安装：
init.sls
{% if grains['osmajorrelease'] == "6" %}
supervisor_install:
cmd.run:
- name: yum install python python-meld3 -y && rpm -Uvh http://****/supervisor-3.0-1.gf.el6.noarch.rpm
{% elif grains['osmajorrelease'] == "7" %}
supervisor:
pkg:
- installed
{% endif %}
/etc/supervisord.d/:
file.directory:
- makedirs: True
- mode: 755
/etc/supervisord.conf:
file.managed:
- source: salt://supervisord/files/supervisord.conf
- backup: minion
- template: jinja
/etc/supervisord.d/templet.ini:
file.managed:
- source: salt://supervisord/files/templet.ini
supervisord:
service.running:
- watch:
- file: /etc/supervisord.conf
- reload: True
- enable: True
salt安装：salt “*” state.sls supervisord
supervisor安装完成后，会生成supervisord（supervisor守护进程）、supervisorctl（客户端）、echo_supervisord_conf（生成配置文件），
二、 配置文件
cat /etc/supervisord.conf
[unix_http_server]
file=/var/tmp/supervisor.sock ;socket 文件，supervisorctl 会使用
[inet_http_server]
port=ip:9001 ;Web管理后台运行的IP和端口，建议监听内网ip
[supervisord]
logfile=/var/log/supervisor/supervisord.log
logfile_maxbytes=50MB ;日志文件大小，超出会rotate，默认 50MB，如果设成0，表示不限制大小
logfile_backups=10 ;日志文件保留备份数量默认10，设为0表示不备份
loglevel=info
pidfile=/var/run/supervisord.pid
nodaemon=false
minfds=1024
minprocs=200
[rpcinterface:supervisor]
supervisor.rpcinterface_factory
[supervisorctl]
serverurl=http://ip:9001
[include]
files = supervisord.d/*.ini
cat /etc/supervisord.d/templet.ini (进程模版，来自saltstack)
;[program:templet]
;command=/www/webcode/templet/bin/catalina.sh run
;user=appuser
;autostart=true
;autorestart=true
;startretries=3
;stopsignal=QUIT
;stopasgroup=true
;killasgroup=true
;stdout_logfile=/www/webcode/templet/logs/catalina.out
;redirect_stderr=true
;environment=JAVA_HOME=/opt/java
;stdout_capture_maxbytes=1024MB
;stdout_events_enabled=true
具体见：http://supervisord.org/configuration.html
三、 启动supervisor：
supervisord -c /etc/supervisord.conf
systemctl start supervisord
/etc/init.d/supervisord start
四、 supervisorctl使用
通过supervisorctl对进程进行管理：
supervisorctl help
五、 Web管理：地址见配置文件
http://localip:9001，可以进行进程的重启，日志查看等操作
六、 多主机统一管理：
官方推荐：http://supervisord.org/plugins.html
cesi：Web-based dashboard written in Python.
Django-Dashvisor：Web-based dashboard written in Python. Requires Django 1.3 or 1.4.
Nodervisor：Web-based dashboard written in Node.js.
Supervisord-Monitor：Web-based dashboard written in PHP.
SupervisorUI：Another Web-based dashboard written in PHP.
supervisorclusterctl：Command line tool for controlling multiple Supervisor instances using Ansible.
suponoff：Web-based dashboard written in Python 3. Requires Django 1.7 or later.
Supvisors：Designed for distributed applications, written in Python 2.7. Includes an extended XML-RPC API and a Web-based dashboard.
目前我们自己使用Supervisord-Monitor，可以通过dash来管理不同服务器上Supervisord进程，重启、停止、日志查看等。具体截图如下：
