0. 运维监控工具选择 1. 安装脚本(主服务) 常规安装环境搭建太复杂, dashboard安装碰到python依赖不容易解决, 直接使用docker安装, 这里总结除了一个安装 shell script, 如下: #!/bin/sh ## env params MYSQL_HOST=my.falcon.local MYSQL_PASSWORD=falcon MYSQL_USER=falcon ## init mysql table before the first running # cd /tmp && \ # git clone --depth=1 https://github.com/open-falcon/falcon-plus && \ # cd /tmp/falcon-plus/ && \ # for x in `ls ./scripts/mysql/db_schema/*.sql`; do # echo init mysql table $x ...; # docker exec -i falcon-mysql mysql -h $MYSQL_HOST -u $MYSQL_USER -p $MYSQL_PASSWORD < $x; # done ## falcon redis docker run --name falcon-redis --restart

大规模机器集群-故障自动处理(二)

本篇开始介绍具体的实现过程，为表述方便，先定义一些名词， _AutoRepairSystem: _ 故障自动维修系统, 缩写为ARS 原子操作：任务的最小操作，机器任务通常是指重启、重装运维人员：运维工程师= SRE = OP，系统工程师 = sys 远程管理工具：远程控制操作物理机器的工具，如ipmi、ilo 先来看ARS的整体视图和流程图， ARS的工作流程，故障检测: 每5分钟发起一次故障检测，获取当前时刻整个集群的故障机器列表，推送到工作流子系统安全策略: 遍历故障机器列表，依次执行安全策略，过滤不符合要求的机器，得到一个可安全执行重启、重装的机器列表服务离线: 遍历可安全操作的机器列表，执行服务离线故障维修: 服务离线后，发起重启、维修操作，轮询机器状态，直至重启成功或维修完成环境初始化: 执行环境初始化，保证机器环境符合业务需求服务上线: 恢复服务，检查服务达到可服务状态，流程结束接下来将介绍工作流子系统，这是所有具体操作任务执行的基础；再依次介绍上述流程中的关键环节：服务上下线，故障检测，安全策略，维修工具及SLA; 然后通过一个线上例子，说明整体的工作流程；最后分享系统上线后的运行数据。 2.1 工作流子系统工作流最基本的功能，是驱动一系列预定义任务顺序执行，达到明确的结束状态；在机器故障自动处理这个问题域里，对工作流还有闭环

问题 Before asking the question i want to mention that i am aware of the fact that i can use django instead to make the app, but i need to use falcon and nothing else. i am just looking for an approach lets take a very simple scenario so that i can understand how data flows between various parts of the app. i have a simple login page using html: <!DOCTYPE html> <html> <body> <form action="***what-do-i-put-here***"> <fieldset> <legend>Personal information:</legend> First name:<br> <input type="text

本文面向想通过Python学习公众号开发的同学。一站式解决新手开发微信公众号遇到的所有问题。为了防止我的文章被到处转载，贴一下我的公众号【智能制造社区】，欢迎大家关注。 github仓库地址 https://github.com/injetlee/Python/tree/master/wechat 本篇文章首先实现与公众号的对接，实现简单的回复文字、图片内容。下一篇会对接腾讯的AI平台，实现对照片的人脸检测与分析，分析年龄、性别、表情、魅力值等。准备工作首先要注册一个公众号，这个很简单，我们到微信公众平台注册就可以了，选择个人订阅号就可以。但是如果可以认证的，我建议选择认证订阅号，因为未认证的号很多功能权限都没有。好了，话不多说进入正题。 1. 配置公众号打开公众号，在开发->基本配置页面填写内容。下面说下需要填的内容，第一个URL要填的就是我们的服务地址，这个地址必须是外网地址并且是80端口。我们要本地开发时可以用 ngrok 解决。在ngrok.com官网下载。解压后就是一个exe程序。在当前目录下输入 .\ngrok.exe http 80 即可启动。启动后如下图所示，图片中网址就是我们需要的然后我们复制红色方框里面的地址到微信的URL输入框中，比如我的就输入http://c9b15df5.ngrok.io/connect
