Linux離線下安裝配置docker

由於網絡隔離的原因,部分服務器如數據庫服務器沒有互聯網訪問環境,需要離線安裝docker.

---

• 一、離線下載docker, 選擇最新版本的Ce版本就好,

   Docker CE是免費的Docker產品的新名稱，Docker CE包含了完整的Docker平臺，非常適合開發人員和運維團隊構建容器APP。

• 二、 sftp上傳到目標服務器(過程略)
• 三、解壓文件

  #tar -xvf docker-18.06.3-ce.tar

• 四、複製文件到 /usr/bin

  #cp docker/* /usr/bin/

複製到 /usr/bin 相當於配置了path，命令終端裏能調用 docker 命令。

• 五、配置docker

由於是離線安裝，所以需要手動添加 docker.service配置文件。

修改一下docker默認鏡像和容器在系統中的磁盤目錄

注意這一行要改成自己的配置 

ExecStart=/usr/bin/dockerd --graph=/MysqlDb/docker --storage-driver=overlay 

# Docker默認的鏡像和容器存儲位置在/var/lib/docker中

# 修改docker.service文件，指定鏡像倉庫目錄

 vim /etc/systemd/system/docker.service

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd --graph=/MysqlDb/docker --storage-driver=overlay --registry-mirror=https://s42tycw4.mirror.aliyuncs.com
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s

[Install]
WantedBy=multi-user.target

 

• 六、啓動Docker

chmod +x /etc/systemd/system/docker.service #添加文件權限並啓動docker
systemctl daemon-reload #重載unit配置文件
systemctl start docker #啓動Docker
systemctl enable docker.service #設置開機自啓

• 七、驗證

systemctl status docker #查看Docker狀態

docker -v #查看Docker版本
