近期,須要在CentOS 7上安裝dokcer環境,特記錄下如何基於阿里雲代理實現。linux
(1)備份原鏡像git
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
(2) 下載新的CentOS-Base.repogithub
#僅針對CentOS7 wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
(3) 生成緩存docker
yum makecache
(4)消除可能的告警json
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
以上內容摘抄自https://developer.aliyun.com/mirror/centoscentos
(1)安裝必要工具緩存
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
(2)添加軟件源信息bash
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
(3)更新yum緩存app
sudo yum makecache fast
(4)安裝docker運維
sudo yum -y install docker-ce
(5)啓動docker後臺服務
sudo systemctl start docker sudo systemctl enable docker
(6) 配置阿里雲鏡像加速器
# 不設置,鏡像的下載速度實在是堪憂 sudo mkdir -p /etc/docker # 注意,配置的網址能夠更換爲本身的配置,登陸阿里雲在控制檯中尋找鏡像加速器 sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://s3w3uu4l.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker
(7)基於DAOCLOUD安裝docker-compose
# 最近github很不穩定,仍是使用daocloud完成安裝 curl -L https://get.daocloud.io/docker/compose/releases/download/1.26.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose
若是運維未給你設置NTP服務,那麼就本身動手,避免給之後挖坑。
# 編輯/etc/ntp.conf文件,設置以下內容 driftfile /var/lib/ntp/drift pidfile /var/run/ntpd.pid logfile /var/log/ntp.log restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery restrict 127.0.0.1 server 127.127.1.0 fudge 127.127.1.0 stratum 10 server ntp.aliyun.com iburst minpoll 4 maxpoll 10 restrict ntp.aliyun.com nomodify notrap nopeer noquery
