两句话讲清楚离线安装docker
目录写在前面
-
背景:银河麒麟、离线环境,装吧,一装一个不吱声。
-
参考链接:https://blog.csdn.net/zhaogangyyxf/article/details/141328640
-
准备:
-
docker安装包:文件类型是一个压缩包。一般是要去docker官网下的,懂我意思吧,不过之前国内镜像不好使,又突然好使了,比如 阿里的镜像,进去下载就行。
CE
版本是什么意思,就是Community Edition
,社区版,更新会频繁一些,不是很稳定,所以一般下普通的就行。 -
docker-compose:文件类型是一个二进制文件。虽然你找的是docker,但后面肯定也要用到docker-compose,教程也一并给出。比起docker不好弄,docker-compose稍微方便一点,从github上直接下。
Docker 主要是用来管理单个容器,而 Docker Compose 则是用来组织和编排多个容器,形成一个完整的、多服务的应用环境
-
解决方案
-
编写
docker.service
脚本,后面要用,不懂?抄就完了。写了放哪儿?跟docker、docker-compose同一级先放着吧。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

解压docker,移动到
/usr/bin/
目录。本地解压的删不删随你,反正没用了:rm -rf docker/
这里的
-*
是让你写自己的版本,别照抄啊tar -xvf docker-*.tgz cp -p docker/* /usr/bin/
-
移动docker-compose到
/usr/local/bin/
目录,且改名为docker-compose
,增加执行权限,依然删不删随你这里的
-*
是让你写自己的版本,别照抄啊cp docker-compose-* /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose
-
移动docker.service,刚让你抄的那个,到
/etc/systemd/system/
目录,增加执行权限,依然删不删随你cp docker.service /etc/systemd/system/ chmod +x /etc/systemd/system/docker.service
-
重新加载配置文件,启动docker,设置开机自启
systemctl daemon-reload systemctl start docker systemctl enable docker.service
-
完成了已经,检查一下吧
docker -v docker-compose -v
