##Supervisor

##Centos Supervisor安裝

###要求 python環境 由於是一個 Python 程序 [root@localhost wang]# python -V Python 2.7.5

yum install python-setuptools
   easy_install supervisor

###驗證： 成功安裝後能夠登錄python

>>> import supervisor

查看是否能成功加載 ###Supervisor配置

echo_supervisord_conf > /etc/supervisord.conf

supervisor自帶有Web Server, 能夠經過頁面來管理進程

[inet_http_server] ; inet (TCP) server disabled by default port=127.0.0.1:9001 ; (ip_address:port specifier, *:port for all iface) ;username=user ; (default is no username (open server)) ;password=123 ; (default is no password (open server))

###啓動supervisor：

supervisord -c /etc/supervisord.conf

[root@localhost wang]# ps -ef |grep supervisord root 24673 1 0 07:19 ? 00:00:00 /usr/bin/python /usr/bin/supervisord

supervisord 是後臺管理服務器, 用來依據配置文件的策略管理後臺守護進程; supervisorctl 用於管理員向後臺管理程序發送 啓動/重啓/中止 等指令

##docker Container同時啓動多服務

###建立Dockerfile:

# use this image to run multiple service
# add service in supervisord.conf

FROM centos:latest
MAINTAINER edwardsbean@gmail.com
RUN yum install -y supervisor
RUN mkdir -p /var/run/sshd
RUN mkdir -p /var/log/supervisor
ADD supervisord.conf /etc/supervisord.conf
# expose your port to host
EXPOSE 22 80

建立supervisord.conf

[supervisord]
nodaemon=true

[program:sshd]
command=/usr/sbin/sshd -D

[program:redis]
command=redis-server /etc/redis/redis.conf

###build鏡像

#!/bin/bash
docker build -f /home/wang/scripts/docker/Dockerfile -t myredis .
