centos7安装docker和docker-compose

一.安装docker

1.安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

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

[root@izm5e2q95pbpe1hh0kkwoiz ~]# yum install -y yum-utils device-mapper-persistent-data lvm2

base                                                                                            | 3.6 kB  00:00:00     
bintray-rabbitmq-server                                                                         | 1.3 kB  00:00:00     
epel                                                                                            | 4.7 kB  00:00:00

......

2.设置yum源

• yum-config-manager --add-repo http://download.docker.com/linux/centos/docker-ce.repo（中央仓库）
• yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo（阿里仓库）

[root@izm5e2q95pbpe1hh0kkwoiz ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo

3.可以查看所有仓库中所有docker版本，并选择特定版本安装

yum list docker-ce --showduplicates | sort -r

[root@izm5e2q95pbpe1hh0kkwoiz ~]# yum list docker-ce --showduplicates | sort -r

完毕！

5.没启动docker之前查看docker版本

[root@izm5e2q95pbpe1hh0kkwoiz ~]# docker -v
Docker version 19.03.12, build 48a66213fe
[root@izm5e2q95pbpe1hh0kkwoiz ~]# docker version
Client: Docker Engine - Community
 Version:           19.03.12
 API version:       1.40

 Experimental:      false
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

6.启动docker之后查看docker版本

[root@izm5e2q95pbpe1hh0kkwoiz ~]# docker -v
Docker version 19.03.12, build 48a66213fe
root@izm5e2q95pbpe1hh0kkwoiz ~]# docker version

二.安装docker-compose

1.方法一.官网方法(docker.com)

注意事项

1. mac和windows客户端下安装完docker之后,docker-compose是带着的
2. linux系统下,需要先安装docker,然后再安装docker-compose
3. 以非root用户运行docker-compose

①下载最新稳定版本

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-\((uname -s)-\)(uname -m)" -o /usr/local/bin/docker-compose

②赋予文件执行权限

sudo chmod +x /usr/local/bin/docker-compose

③建立一个软链到/usr/bin/目录下

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

④查看版本

docker-compose --version

2.通过pip进行安装

①安装pip

yum -y install epel-release
yum -y install python-pip

②查看版本

pip --version 或 pip -V

③更新pip

pip install --upgrade pip

④安装docker-compose

pip install docker-compose 

⑤查看docker compose的版本

docker-compose version

⑥如果安装出错

Cannot uninstall ‘requests’. It is adistutils installed project and thus we cannot accurately determine which filesbelong to it which would lead to only a partial uninstall.

解决方法

pip install docker-compose--ignore-installed requests

没有任何错误，会出现安装成功界面

3.离线安装

①访问https://github.com/docker/compose/releases，获取docker-compose-Linux-x86_64下载链接

https://github.com/docker/compose/releases/download/1.26.0/docker-compose-Linux-x86_64

②下载docker-compose-Linux-x86_64到/usr/local/bin/

[root@izm5e2q95pbpe1hh0kkwoiz bin]# wget https://github.com/docker/compose/releases/download/1.26.0/docker-compose-Linux-x86_64
--2020-06-29 10:41:41--  https://github.com/docker/compose/releases/download/1.26.0/docker-compose-Linux-x86_64
正在解析主机 github.com (github.com)... 13.229.188.59
正在连接 github.com (github.com)|13.229.188.59|:443... 已连接。
......

③重命名docker-compose-Linux-x86_64为docker-compose

[root@izm5e2q95pbpe1hh0kkwoiz bin]# mv docker-compose-Linux-x86_64 docker-compose

④添加可执行权限和查看docker compose版本

# 添加可执行权限
sudo chmod +x /usr/local/bin/docker-compose
# 查看docker-compose版本
docker-compose -v
