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 已加载插件：fastestmirror base                                                                                            | 3.6 kB  00:00:00      bintray-rabbitmq-server                                                                         | 1.3 kB  00:00:00      epel                                                                                            | 4.7 kB  00:00:00      extras   ...... 

2.设置yum源

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

[root@izm5e2q95pbpe1hh0kkwoiz ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 已加载插件：fastestmirror adding repo from: https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo grabbing file https://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 已加载插件：fastestmirror 可安装的软件包 Loading mirror speeds from cached hostfile docker-ce.x86_64            3:19.03.9-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.8-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.7-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.6-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.5-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.4-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.3-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.2-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.1-3.el7                     docker-ce-stable docker-ce.x86_64            3:19.03.12-3.el7                    docker-ce-stable docker-ce.x86_64            3:19.03.11-3.el7                    docker-ce-stable docker-ce.x86_64            3:19.03.10-3.el7                    docker-ce-stable docker-ce.x86_64            3:19.03.0-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.9-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.8-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.7-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.6-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.5-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.4-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.3-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.2-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.1-3.el7                     docker-ce-stable docker-ce.x86_64            3:18.09.0-3.el7                     docker-ce-stable docker-ce.x86_64            18.06.3.ce-3.el7                    docker-ce-stable docker-ce.x86_64            18.06.2.ce-3.el7                    docker-ce-stable docker-ce.x86_64            18.06.1.ce-3.el7                    docker-ce-stable docker-ce.x86_64            18.06.0.ce-3.el7                    docker-ce-stable docker-ce.x86_64            18.03.1.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            18.03.0.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.12.1.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.12.0.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.09.1.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.09.0.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.06.2.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.06.1.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.06.0.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.03.3.ce-1.el7                    docker-ce-stable docker-ce.x86_64            17.03.2.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.03.1.ce-1.el7.centos             docker-ce-stable docker-ce.x86_64            17.03.0.ce-1.el7.centos             docker-ce-stable  

4.安装Docker，命令：yum install docker-ce-版本号

 
yum install docker-ce-19.03.9
 

root@izm5e2q95pbpe1hh0kkwoiz ~]# yum install docker-ce-19.03.9 已加载插件：fastestmirror Loading mirror speeds from cached hostfile 正在解决依赖关系 --> 正在检查事务 ---> 软件包 docker-ce.x86_64.3.19.03.9-3.el7 将被 安装 --> 正在处理依赖关系 container-selinux >= 2:2.74，它被软件包 3:docker-ce-19.03.9-3.el7.x86_64 需要 --> 正在处理依赖关系 containerd.io >= 1.2.2-3，它被软件包 3:docker-ce-19.03.9-3.el7.x86_64 需要 --> 正在处理依赖关系 docker-ce-cli，它被软件包 3:docker-ce-19.03.9-3.el7.x86_64 需要 --> 正在处理依赖关系 libcgroup，它被软件包 3:docker-ce-19.03.9-3.el7.x86_64 需要 ...... 作为依赖被升级:   audit.x86_64 0:2.8.5-4.el7                            audit-libs.x86_64 0:2.8.5-4.el7                                  libselinux.x86_64 0:2.5-15.el7                        libselinux-devel.x86_64 0:2.5-15.el7                             libselinux-python.x86_64 0:2.5-15.el7                 libselinux-utils.x86_64 0:2.5-15.el7                             libsemanage.x86_64 0:2.5-14.el7                       libsepol.x86_64 0:2.5-10.el7                                     libsepol-devel.x86_64 0:2.5-10.el7                    policycoreutils.x86_64 0:2.5-34.el7                              selinux-policy.noarch 0:3.13.1-266.el7                selinux-policy-targeted.noarch 0:3.13.1-266.el7                 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  Go version:        go1.13.10  Git commit:        48a66213fe  Built:             Mon Jun 22 15:46:54 2020  OS/Arch:           linux/amd64  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 Client: Docker Engine - Community  Version:           19.03.12  API version:       1.40  Go version:        go1.13.10  Git commit:        48a66213fe  Built:             Mon Jun 22 15:46:54 2020  OS/Arch:           linux/amd64  Experimental:      false  Server: Docker Engine - Community  Engine:   Version:          19.03.9   API version:      1.40 (minimum version 1.12)   Go version:       go1.13.10   Git commit:       9d988398e7   Built:            Fri May 15 00:24:05 2020   OS/Arch:          linux/amd64   Experimental:     false  containerd:   Version:          1.2.13   GitCommit:        7ad184331fa3e55e52b890ea95e65ba581ae3429  runc:   Version:          1.0.0-rc10   GitCommit:        dc9208a3303feef5b3839f4323d9beb36df0a9dd  docker-init:   Version:          0.18.0   GitCommit:        fec3683 

二.安装docker-compose

1.方法一.官网方法(docker.com)

注意事项

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
