前言
有時候會遇到服務(wù)器不能聯(lián)網(wǎng)的情況，這樣就沒法用yum安裝軟件，docker也是如此，針對這種情況，總結(jié)了一下離線安裝docker的步驟，分享給大家
1. 準(zhǔn)備docker離線包
docker官方離線包下載地址
下載需要安裝的docker版本，我此次下載的是
docker-17.03.2-ce.tgz版本
2. 準(zhǔn)備docker.service 系統(tǒng)配置文件
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
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
3. 準(zhǔn)備安裝腳本和卸載腳本
安裝腳本 install.sh
#!/bin/sh
echo '解壓tar包...'
tar -xvf $1
echo '將docker目錄移到/usr/bin目錄下...'
cp docker/* /usr/bin/
echo '將docker.service 移到/etc/systemd/system/ 目錄...'
cp docker.service /etc/systemd/system/
echo '添加文件權(quán)限...'
chmod +x /etc/systemd/system/docker.service
echo '重新加載配置文件...'
systemctl daemon-reload
echo '啟動docker...'
systemctl start docker
echo '設(shè)置開機自啟...'
systemctl enable docker.service
echo 'docker安裝成功...'
docker -v
卸載腳本 uninstall.sh
#!/bin/sh
echo '刪除docker.service...'
rm -f /etc/systemd/system/docker.service
echo '刪除docker文件...'
rm -rf /usr/bin/docker*
echo '重新加載配置文件'
systemctl daemon-reload
echo '卸載成功...'
4. 安裝
-
4.1 此時目錄為：（只需要關(guān)注docker-17.03.2-ce.tgz、docker.service、install.sh、uninstall.sh即可）
1.PNG - 4.2 執(zhí)行腳本
sh install.sh docker-17.03.2-ce.tgz
執(zhí)行過程如下：
2.PNG
待腳本執(zhí)行完畢后，執(zhí)行docker -v
發(fā)現(xiàn)此時docker已安裝成功，可以用docker --help 查看docker命令，從現(xiàn)在開始你就可以自己安裝image和container了
- 4.3 如果你想卸載docker，此時執(zhí)行腳本
sh uninstall.sh即可，執(zhí)行過程如下：
3.PNG
此時輸入docker -v，發(fā)現(xiàn)docker已經(jīng)卸載
