redash部署使用

一、安装

从https://github.com/getredash/redash, 拉取代码，运行docker-compose.production.yml

1，docker-compose文件调整

主要修改了两处：

1，增加了redis和postgres的db文件与宿主机的映射，不让docker容器停止后数据丢失。

官方默认的docker-compose.production.yml在docker-compose down 命令后，所有的配置信息都丢失了

2，增加了redis和postgres的端口映射，方便调试，线上环境也可以关掉。

3，修改REDASH_COOKIE_SECRET。

修改后的docker-compose.yml文件如下：

# This is an example configuration for Docker Compose. Make sure to atleast update
# the cookie secret & postgres database password.
#
# Some other recommendations:
# 1. To persist Postgres data, assign it a volume host location.
# 2. Split the worker service to adhoc workers and scheduled queries workers.
version: '2'
services:
  server:
    #image: redash/redash:latest # 官方版本升级后不好用了，替换为我保持的版本
    image: cbbing/redash:4.0.1  
    command: server
    depends_on:
      - postgres
      - redis
    ports:
      - "5000:5000"
    environment:
      PYTHONUNBUFFERED: 0
      REDASH_LOG_LEVEL: "INFO"
      REDASH_REDIS_URL: "redis://redis:6379/0"
      REDASH_DATABASE_URL: "postgresql://postgres@postgres/postgres"
      REDASH_COOKIE_SECRET: "Q422k6vaXUk8"
      REDASH_WEB_WORKERS: 4      
    restart: always
  worker:
    image: cbbing/redash:4.0.1 
    command: scheduler
    environment:
      PYTHONUNBUFFERED: 0
      REDASH_LOG_LEVEL: "INFO"
      REDASH_REDIS_URL: "redis://redis:6379/0"
      REDASH_DATABASE_URL: "postgresql://postgres@postgres/postgres"
      QUEUES: "queries,scheduled_queries,celery"
      WORKERS_COUNT: 2
    restart: always
  redis:
    image: redis:3.0-alpine
    ports:
    - "6379:6379"
    volumes: 
      - ./data/redis_data:/data
    restart: always
  postgres:
    image: postgres:9.5.6-alpine
    ports:
    - "5432:5432"
    volumes:
      - ./data/postgresql_data:/var/lib/postgresql/data
    restart: always
  nginx:
    image: redash/nginx:latest
    ports:
      - "88:80"
    depends_on:
      - server
    links:
      - server:redash
    restart: always

2，创建db

[root@VM_38_115_centos redash]# docker-compose run --rm server create_db
 
Starting redash_redis_1
 
Starting redash_postgres_1
 
[2018-09-11 09:02:39,580][PID:1][INFO][root] Generating grammar tables from /usr/lib/python2.7/lib2to3/Grammar.txt
 
[2018-09-11 09:02:39,601][PID:1][INFO][root] Generating grammar tables from /usr/lib/python2.7/lib2to3/PatternGrammar.txt
 
[2018-09-11 09:02:41,707][PID:1][INFO][alembic.runtime.migration] Context impl PostgresqlImpl.
 
[2018-09-11 09:02:41,708][PID:1][INFO][alembic.runtime.migration] Will assume transactional DDL.
 
[2018-09-11 09:02:41,724][PID:1][INFO][alembic.runtime.migration] Running stamp_revision -> 969126bd800f
 

3，运行

# docker-compose up

运行起来的容器如下:

image

运行起来后通过88端口访问

4，邮件配置

For the system to be able to send emails (for example when alerts trigger), you need to set the mail server to use and the host name of your Redash server. If you’re using one of our images, you can do this by editing the .env file:

 
# Note that not all values are required, as they have default values.
 
export REDASH_MAIL_SERVER="" # default: localhost
export REDASH_MAIL_PORT="" # default: 25
export REDASH_MAIL_USE_TLS="" # default: false
export REDASH_MAIL_USE_SSL="" # default: false
export REDASH_MAIL_USERNAME="" # default: None
export REDASH_MAIL_PASSWORD="" # default: None
export REDASH_MAIL_DEFAULT_SENDER="" # Email address to send from
 
export REDASH_HOST="" # base address of your Redash instance, for example: "https://demo.redash.io"

docker-compose文件中配置

server:
    image: redash/redash:latest
    environment:
  
      ...
 
      #邮箱 
      REDASH_MAIL_SERVER: "smtp.exmail.qq.com"
      REDASH_MAIL_PORT: 465
      REDASH_MAIL_USE_TLS: "false"
      REDASH_MAIL_USE_SSL: "true"
      REDASH_MAIL_USERNAME: "[email protected]"
      REDASH_MAIL_PASSWORD: "111111"
      REDASH_MAIL_DEFAULT_SENDER: "[email protected]"
      REDASH_HOST: "http://redash.mysite.com"
 

测试是否配置成功：

 
[root@VM_38_115_centos ~]# docker exec -it redash_server_1 python manage.py send_test_mail
 
[2018-09-11 10:02:28,627][PID:37][INFO][root] Generating grammar tables from /usr/lib/python2.7/lib2to3/Grammar.txt
 
[2018-09-11 10:02:28,649][PID:37][INFO][root] Generating grammar tables from /usr/lib/python2.7/lib2to3/PatternGrammar.txt
 

自己邮件会收到Test message。

PS：配置成功了，但在Alerts中触发了警告，设置的接受邮件没收到警告信息。还没找到原因...

二、使用

1，配置数据库

image

2，查询语句

• 获取表的更新时间

三、用户管理

四、特性

1，支持iframe嵌入到其它网页

对于任何Query，表格和图形都支持embed

image

点击Embed弹出：

这个功能可以实现自己系统中集成报表展示。

2，可视化图形支持的类型

箱型图

image

线形图、柱状图、面积图、饼图、散点图

image

队列图

image

计数器

image

漏斗图

image

地图

image

透视表

image

桑基图

image

桑基图用于表达流量分布于结构对比，最初的发明者使用它来呈现能量的流动与分布。

五，实践

根据scrapy log日志表，设计出一张bashboard监控面板：
