redash安装

如果是通过docker安装的话,获取到redash源码之后找到其setup文件夹下的setup.sh文件,直接执行sh setup.sh 就可以执行1、安装docker；2、安装docker-compose；3、获取redash镜像；4、运行docker-compose.yml文件
非docker安装请参考https://www.cnblogs.com/shhnwangjian/p/8417748.html
setup文件如果是ubuntu16.04系统的话需要修改,也可进行个性化配置。以下是参考:

#!/usr/bin/env bash
# This script setups dockerized Redash on Ubuntu 18.04.
set -eu

REDASH_BASE_PATH=/opt/redash

请务必注释掉wget一行,否则你对本文件夹docker-compose.yml的将无法达到效果。

去掉链接:

阅读源码,找到关键代码位置,修改,测试，打包docker镜像。
已制好的镜像获取方法: docker pull spritinme/redash:noLink
由于没有在本地搭建redash环境,更改过程还是比较艰难的，正好让自己熟悉了docker的一些操作

docker cp

docker cp 可以实现宿主机和容器之间的文件互通，语法如下
docker cp 想要复制的文件 想要复制到的目录

docker exec -it contaierID /bin/bash

可以使用容器内部的命令行，ctrl + p + q 退出容器
docker exec -it contaierID /bin/sh xxx.sh 可以直接执行容器内的shell脚本

redash的页面基本是用node.js写的，使用flask的模板的只有其与账号有关的页面。
