Swarm initialized: current node (vgc6172h94lo7vktpxs9hnb1y) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-0dpoajwlnlig2pvbujiqzogodwilx6fezg7rgpjfsvob49vnzl-1lq8jjz0hqvcmd2ay91ornac6 \

[root@localhost test]# yum install docker
2.启动docker
[root@localhost test]# systemctl start docker
3.运行hello-world
[root@localhost test]# docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/
For more examples and ideas, visit:
https://docs.docker.com/get-started/
4.Docker 以 ubuntu15.10 镜像创建一个新容器，然后在容器里执行 bin/echo "Hello world"，然后输出结果
[root@localhost test]#docker run ubuntu:15.10 /bin/echo "Hello world"
Hello world
5.通过docker的两个参数 -i -t，让docker运行的容器实现"对话"的能力
[root@localhost test]# docker run -i -t ubuntu:15.10 /bin/bash
root@8b6cdcd4f1bb:/# ls
bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var
6.后台模式运行命令
[root@localhost test]# docker run -d ubuntu:15.10 /bin/sh -c "while true; do echo hello world; sleep 1; done"

11.通过命令 docker commit来提交容器副本,创建的目标镜像名
//-m:提交的描述信息,-a:指定镜像作者,d11aaceba824：容器ID,test/lnmp:v1 :指定要创建的目标镜像名
[root@localhost test]# docker commit -m="LNMP" -a="test" d11aaceba824 test/lnmp:v1

12.设置镜像标签
docker tag 镜像ID，这里是 860c279d2fec ,用户名称、镜像源名(repository name)和新的标签名(tag)。
使用 docker images 命令可以看到，ID为860c279d2fec的镜像多一个标签。

2.启动hadoop
#hdfs namenode -format #start-all.sh #hadoop fs -mkdir -p HDFS_INPUT_PV_IP
3.查看案例日志

9.查看数据库的统计结果
10.查看/tmp/pvlog.txt的清洗结果
11.重复运行处理数据，需要删除已经存在的输出目录
