Docker上安装部署Superset

一、Docker上安装部署Superset

二、Superset配置MySQL的数据源

一、Docker上安装部署Superset

• Docker一定要在CentOS7上的机器进行部署，否则会出现问题

1、查看正在运行中的镜像
[root@hadoop001 ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

2、查看所有已经安装的镜像
[root@hadoop001 ~]# docker images
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
mysql                 5.7                 f965319e89de        4 days ago          448MB
amancevice/superset   0.28.1              389762d7c335        12 months ago       1.41GB

3、因为我们要使用8088端口，所以需要先检测8088端口是否被占用了：
[root@hadoop001 ~]# netstat -nlp|grep 8088

4、-d表示该容器程序后台执行，-p表示映射的端口号，--name表示为该容器指定一个名字，最后带上版本号进行启动：
[root@hadoop001 ~]# docker run -d -p 8088:8088 --name superset amancevice/superset:0.28.1
9c2b2d2eecdfe599d9887a3058fe5c3b65d4e4dae89cb8da60824f90b8900acd

5、查看该容器是否正在运行：
[root@hadoop001 ~]# docker ps
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS                            PORTS                               NAMES
9c2b2d2eecdf        amancevice/superset:0.28.1   "gunicorn superset:a…"   6 seconds ago       Up 4 seconds (health: starting)   8088/tcp, 0.0.0.0:32768->8890/tcp   superset

6、运行superset进入bin/bash内部：
[root@hadoop001 ~]# docker exec -it 9c2b2d2eecdf superset-init
Username [admin]: john
User first name [admin]: john
User last name [user]: john
Email [[email protected]]: 2
Password: 
Repeat for confirmation: 
Error: the two entered values do not match

7、对superset的数据库进行更新：
superset@9d9cb8fe2cce:~$ superset db upgrade
2020-05-02 13:29:44,183:ERROR:flask_appbuilder.base:'NoneType' object has no attribute 'name'
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/flask_appbuilder/base.py", line 470, in _add_permission
    self.sm.add_permissions_view(baseview.base_permissions, baseview.__class__.__name__)
  File "/usr/local/lib/python3.6/site-packages/flask_appbuilder/security/manager.py", line 923, in add_permissions_view
    if perm_view.permission.name not in base_permissions:

8、对superset进行初始化：
superset@9d9cb8fe2cce:~$ superset init
2020-05-02 13:29:57,079:ERROR:flask_appbuilder.base:'NoneType' object has no attribute 'name'
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/flask_appbuilder/base.py", line 470, in _add_permission

9、运行docker中的runserver：
superset@9d9cb8fe2cce:~$ superset runserver
2020-05-02 13:30:12,579:INFO:root:The Gunicorn 'superset runserver' command is deprecated. Please use the 'gunicorn' command instead.
Starting server with command: 
gunicorn -w 2 --timeout 60 -b  0.0.0.0:8088 --limit-request-line 0 --limit-request-field_size 0 superset:app

[2020-05-02 13:30:17 +0000] [82] [ERROR] Can't connect to ('0.0.0.0', 8088)

注意：云主机是否开放8088端口一定要注意，虽然会报种种错误，咱也看不懂啊，咱也不敢问啊

完美无问题

二、Docker配置MySQL的数据源

1、首先需要知道Superset默认的数据源是配置在哪儿的？

因为我们在Linux上也部署了MySQL，docker上也部署了MySQL的镜像文件，我们先选择把数据源修改为MySQL文件；

• 为什么docker images查询到的显示如下，原因是什么呢？
  因为我重新启动了这个进程之后

[root@hadoop002 ~]# docker images
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
[root@hadoop002 ~]# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
   Active: inactive (dead)
     Docs: https://docs.docker.com
[root@hadoop002 ~]# systemctl start docker
[root@hadoop002 ~]# docker images
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
mysql                 5.7                 f965319e89de        4 days ago          448MB
amancevice/superset   0.28.1              389762d7c335        12 months ago       1.41GB

You have to remove (or rename) that container to be able to reuse that name.

• 再次使用这个命令启动发现报错如下：docker run -d -p 8088:8088 --name superset amancevice/superset:0.28.1
  解决：使用docker ps -l显示（-l 是显示最新创建的容器包括所有状态）

1、查看已经启动过的进程，不管现在的状态是否停止过：
[root@hadoop002 ~]# docker ps -l
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS                      PORTS               NAMES
9d9cb8fe2cce        amancevice/superset:0.28.1   "gunicorn superset:a…"   About an hour ago   Exited (0) 15 minutes ago                       clever_mendeleev

2、启动这个容器：
[root@hadoop002 ~]# docker start 9d9cb8fe2cce
9d9cb8fe2cce
[root@hadoop002 ~]# netstat -nlp|grep 8088
tcp6       0      0 :::8088                 :::*                    LISTEN      2471/docker-proxy   

• 解析：mysql://root:[email protected]/superset?charset=utf8 --> root表示访问数据库的用户名，960210访问数据库的密码，47.98.238.163表示数据库所在机器IP地址，superset表示相应要连接的数据库，?charset=utf8表示的是允许中文字符集不会出现乱码
