第四百零五节，centos7下搭建sentry错误日志服务器，接收python以及Django错误，

sudo yum remove docker     docker-common     docker-selinux     docker-engine

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

sudo yum-config-manager     --add-repo     https://download.docker.com/linux/centos/docker-ce.repo

sudo yum makecache fast

sudo yum install docker-ce

sudo systemctl start docker

sudo docker run hello-world

输出：

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.
 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
