集中式日志分析方案

使用技术：Filebeat + kafka + logstash + elasticsearch + kibana
(日志采集) （传输） （数据收集整理） （数据存储搜索分析） （数据分析可视化）

Logger

这里使用slf4j+logback的组合，首先需要注意是否与某些依赖继承的log4j冲突，需要把它exculusion,如果存在，slf4j会报找到多个binding的实现，然后会自己选取一种。
slf4J 是 简单日志门面（simple logger facade），并没有具体的日志实现，只提供一组接口，这样用户就无需，因为不同的底层实现而编写不同的代码。
首先需要依赖logback-classic和slf4j-api。如果使用的是log4j还需要slf4j-log4j12 作为连接。
对于logback其配置文件为resource下的logback.xml。
配置例如：

<logger name="ELKLogger" level="DEBUG" additivity="true">

Install MySQL 5.7 on macOS using Homebrew

This is a fork of original gist https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe137b58e, with slight changes on pointing to 5.7 version branch, instead of 8 (latest default of MySQL in Hombrew).

Install MySQL 5.7 on macOS

This procedure explains how to install MySQL using Homebrew on macOS (Sierra 10.12 and up)

Install Homebrew

  • Installing Homebrew is effortless, open Terminal and enter :
    $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  • Note: Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.

Setup prometheus-node-exporter and push stats to Pushgateway with cron job

(Assuming a Debian 8-like system)

  • Install prometheus-node-exporter

    $ sudo apt update && sudo apt install prometheus-node-exporter

  • Configure prometheus-node-exporter to expose metrics only to localhost, not on to all networks. Modify file /etc/default/prometheus-node-exporter:

    # Set the command-line arguments to pass to the server.

Connect to another host with your docker client, without modifying your local Docker installation

Run commands on remote Docker host

This is how to connect to another host with your docker client, without modifying your local Docker installation or when you don't have a local Docker installation.

Enable Docker Remote API

First be sure to enable the Docker Remote API on the remote host.

This can easily be done with a container.
For HTTP connection use jarkt/docker-remote-api.

retrieve EC2's region from instance metadata

Sometimes you want to retrieve EC2 insntances' region information.

You can query that information through instance metadata(169.254.169.254).

$ curl --silent http://169.254.169.254/latest/dynamic/instance-identity/document
{
  "privateIp" : "172.31.2.15",
  "instanceId" : "i-12341ee8",
  "billingProducts" : null,
 "instanceType" : "t2.small",
