CentOS7中如何安裝docker

本篇文章給大家分享的是有關(guān)CentOS7中如何安裝docker，小編覺得挺實(shí)用的，因此分享給大家學(xué)習(xí)，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。

1. 使用鏡像倉庫進(jìn)行安裝（首次安裝需要設(shè)置docker鏡像倉庫）

```
安裝所需要的軟件包
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
```

2. 設(shè)置stable鏡像倉庫。

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

開始docker安裝：

1. 更新yum軟件包索引

```
#yum installmakecache fast
```

2. 安裝最新版本的docker ce

```
# yum install docker-ce
```

3. 啟動(dòng)docker

```

[root@wg001 ~]# systemctl  start docker

```

4. 驗(yàn)證是否安裝了docker，方法是運(yùn)行hello-world 鏡像

```
[root@wg001 ~]# docker run hello-world

```

輸出內(nèi)容

```
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/

```

5. 卸載docker ce

```
#yum remove docker-ce
#rm -rf /var/lib/docker
```

以上就是CentOS7中如何安裝docker，小編相信有部分知識(shí)點(diǎn)可能是我們?nèi)粘９ぷ鲿?huì)見到或用到的。希望你能通過這篇文章學(xué)到更多知識(shí)。更多詳情敬請(qǐng)關(guān)注億速云行業(yè)資訊頻道。
