網上有N多離線安裝的教程，但都不是在無網絡環境下安裝 ，在這里我會記錄在服務器無網絡環境下離線安裝CICD所需環境的完成過程

本篇記錄無網絡環境安裝docker+docker compse的過程
首先下載離線docker 和docker compose離線安裝包
這里注意不要下載rpm離線安裝包，因為會有可能因為系統中的包版本不對導致安裝docker rpm 包時出現依賴錯誤，但由於服務器無法連接網絡導致boom~
docker 離線包下載地址：https://download.docker.com/linux/static/stable/
docker compose 離線包下載地址：https://github.com/docker/compose/releases
這里我下載的是docker-19.03.9版本
1. 安裝docker
1.1 將離線包上傳到服務器上，執行以下腳本：
tar xzvf docker-19.03.9.tgz cp docker/* /usr/bin/ dockerd &
如果中途沒有報錯，則說明安裝成功，可以用docker info 命令測試以下是否可以正常顯示
如果出現報錯，則執行以下命令情況剛剛的安裝，並重新執行1.中的腳本
rm -rf /var/run/docker rm -rf /var/lib/docker rm -rf /var/run/docker.pid rm -rf /var/run/docker.sock文件 ps -aux | grep docker 停止docker相關進程 netstat -nplt | grep docker 解除docker相關進程占用端口
1.2 設置docker為系統服務
1.2.1 配置containerd
命令如下：
mkdir /etc/containerd containerd config default > /etc/containerd/config.toml touch /usr/lib/systemd/system/containerd.service vi /usr/lib/systemd/system/containerd.service
containerd.service 內容如下：
[Unit]
Description=containerd container runtime
Documentation=https://containerd.io
After=network.target[Service]
ExecStartPre=/sbin/modprobe overlay
ExecStart=/usr/bin/containerd # 這是你 containerd 文件的放置路徑
Delegate=yes
KillMode=process
LimitNOFILE=1048576
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNPROC=infinity
LimitCORE=infinity[Install]
WantedBy=multi-user.target
執行以下命令啟動containerd服務並查看服務的狀態：
systemctl daemon-reload
systemctl enable containerd.service
systemctl start containerd.service
systemctl status containerd.service
1.2.2 配置docker.socket
命令如下：
groupadd docker touch /usr/lib/systemd/system/docker.socket vi /usr/lib/systemd/system/docker.socket
docker.socket文件內容如下：
[Unit]
Description=Docker Socket for the API
PartOf=docker.service[Socket]
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=root
# 如果出現錯誤：chown socket at step GROUP: No such process, 可以修改下面的 SocketGroup=root 或創建 docker 用戶組（命令 groupadd docker）
SocketGroup=docker[Install]
WantedBy=sockets.target
執行以下命令啟動containerd服務並查看服務的狀態：
systemctl daemon-reload
systemctl enable containerd.service
systemctl start containerd.service
systemctl status containerd.service
1.2.3 配置docker.service服務
執行以下命令：
touch /usr/lib/systemd/system/docker.service vi /usr/lib/systemd/system/docker.service
docker.service文件內容如下：
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
BindsTo=containerd.service
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
Requires=docker.socket[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 -H fd:// --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s# 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# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity# 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[Install]
WantedBy=multi-user.target
在啟動服務之前需要先對服務進行解禁操作，執行以下命令：
systemctl unmask docker.service
systemctl unmask docker.socket
執行以下命令載入服務：
chmod +x /usr/lib/systemd/system/docker.service systemctl daemon-reload systemctl enable docker systemctl start docker
systemctl status docker
如果出現啟動docker失敗，可以嘗試重啟服務器，我這里重啟后docker狀態就正常了
2. 安裝docker compose
將docker compose 離線安裝包上傳至服務器，在安裝包目錄下執行以下命令：
mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose docker-compose -v
如出現docker-compose 命令不存在
可執行下列命令，增加鏈接：
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
到這里就安裝完成了。
