Linux伺服器離線安裝Docker

環境說明

CentOS等Linux作業系統基本是一樣的，根據CPU架構[ARM、AMD|X86]選擇對應的tgz包即可

• 作業系統:統信UOS20
• CPU架構:ARM

安裝步驟

本文章示例下載下傳的tgz包為:docker-23.0.1.tgz

• 步驟一:

  選擇CPU為ARM架構的tgz包進行下載下傳:https://download.docker.com/linux/static/stable/aarch64

• 步驟二:

  解壓tgz包(完成後是一個docker檔案夾):tar -zxvf docker-23.0.1.tgz

• 步驟三:

  将docker目錄拷貝到/user/bin下(會提示是否覆寫/usr/bin/runc，覆寫即可):cp docker/* /usr/bin/

• 步驟四:

  系統注冊docker.service服務，對檔案進行編輯:vi /etc/systemd/system/docker.service

  添加以下内容:

[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 --selinux-enabled=false --insecure-registry=127.0.0.1
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           

• 步驟五:

  docker.service檔案添加可執行權限:chmod +x /etc/systemd/system/docker.service

• 步驟六:

  重新加載配置檔案:systemctl daemon-reload

• 步驟七:

  啟動docker服務:systemctl start docker

• 步驟八:

  檢驗docker服務啟動狀态:systemctl status docker

  列印日志如下所示:

• 步驟九:

  檢視docker資訊，確定安裝的就是自己安裝的版本:docker info

• 步驟十:

  設定伺服器開機自啟動:systemctl enable docker.service
