一 docker安裝-CentOS系統
注意：也可新增阿里雲GPG：
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
注意：若存在舊版本可執行以下命令解除安裝舊版本——
apt-get remove docker docker-engine docker-common container-selinux docker-selinux
1.1 docker自動安裝指令碼
1 [email protected]:~# wget -qO- https://get.docker.com/ | sh 2 或—— 3 [email protected]:~# curl -sSL https://get.docker.com/ | sh注意：若出現以下錯誤，可使用yum解決依賴—— Delta RPMs disabled because /usr/bin/yum provides applydeltarpmnot installed.
1 yum provides applydeltarpm #查詢缺少的applydeltarpm所在包 2yum install libdevmapper* -y 3 yum -y install deltarpm #安裝此包 4 yum install -y epel-release #有可能會依舊提示錯誤，安裝此包即可 5 [email protected]:~# docker version #查詢docker版本
1.2 docker yum安裝
1 [email protected]:~# yum -y remove docker \ 2 docker-client \ 3提示：也可使用國內阿里雲——docker-client-latest \ 4 docker-common \ 5 docker-latest \ 6 docker-latest-logrotate \ 7 docker-logrotate \ 8 docker-selinux \ 9 docker-engine-selinux \ 10 docker-engine #若存在舊版需要全新安裝可解除安裝舊版 11[email protected]:~# yum -y update 12 [email protected]:~# yum install -y yum-utils \ 13 device-mapper-persistent-data \ 14 lvm2 15 [email protected]:~# yum-config-manager \ 16 --add-repo \ 17 https://download.docker.com/linux/centos/docker-ce.repo #配置docker源
1 [email protected]:~# yum-config-manager \ 2 --add-repo \ 3 http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 4 [email protected]:~# yum-config-manager --enable docker-ce-edge #開啟源 5 [email protected]:~# yum-config-manager --enable docker-ce-test #開啟源 6 [email protected]:~# yum -y install docker-ce #安裝docker 7 [email protected]:~# yum -y install docker-registry #安裝docker倉庫 8 [email protected]:~# systemctl start docker.service 9 [email protected]:~# systemctl enable docker.service #設為開機啟動
二 docker安裝-Ubuntu系統
2.1 更新源資料庫
1 [email protected]:~# apt-get remove docker docker-engine docker.io #解除安裝舊版 2 [email protected]:~# sudo apt-get update
2.2 安裝軟體包
1 [email protected]:~# sudo apt-get -y install \ 2 apt-transport-https \ 3 ca-certificates \ 4 curl \ 5 software-properties-common #安裝軟體包以允許apt通過HTTPS使用儲存庫
2.3 新增Docker的官方GPG金鑰
1 [email protected]:~# curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
注意：也可新增阿里雲GPG：
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
2.4 驗證祕鑰指紋
1 [email protected]:~# sudo apt-key fingerprint 0EBFCD88
2.5 配置倉庫並在此更新源
1 [email protected]:~# sudo add-apt-repository \ 2 "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ 3 $(lsb_release -cs) \ 4 stable" 5 [email protected]:~# sudo apt-get update注意：國內建議配置為阿里倉庫，命令如下：
1 [email protected]:~# sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" 2 [email protected]:~# sudo apt-get update
2.6 安裝docker ce
1 [email protected]:~# sudo apt-get -y install docker-ce
2.7 測試並檢視版本
1 [email protected]:~# sudo docker run hello-world 2 [email protected]:~# sudo docker version
注意：若存在舊版本可執行以下命令解除安裝舊版本——
apt-get remove docker docker-engine docker-common container-selinux docker-selinux
三 docker相關優化
3.1 配置docker加速器
1 [email protected]:~# mkdir -p /etc/docker 2 [email protected]cker:~# vim /etc/docker/daemon.json 3 { 4 "registry-mirrors": ["https://dbzucv6w.mirror.aliyuncs.com"] 5 } 6 [email protected]:~# cat /etc/docker/daemon.json 7 { 8 "registry-mirrors": ["https://dbzucv6w.mirror.aliyuncs.com"] 9 } 10 [email protected]:~# systemctl daemon-reload 11 [email protected]:~# systemctl restart docker 12 [email protected]:~# sudo systemctl enable docker提示：docker通過https://hub.docker.com/搭建映象共享生態系統，由於從國外拉取源比較慢，建議配置國內阿里加速器。
3.2 更改docker映象路徑
1 [email protected]:~# vi /usr/lib/systemd/system/docker.service 2 ExecStart=/usr/bin/dockerd-current --graph=/data/docker #僅需要追加新路徑 3 [email protected]:~# systemctl daemon-reload 4 [email protected]:~# systemctl restart docker參考： https://docs.docker.com/install/
