离线安装docker

Posted 2021-09-18 wx6144491ba79ae

下载docker镜像

https://download.docker.com/linux/static/stable/x86_64/

1、解压

tar -xvf docker-18.06.1-ce.tgz

2、将解压出来的docker文件内容移动到 /usr/bin/ 目录下

cp docker/* /usr/bin/

3、将docker注册为service

vim /etc/systemd/system/docker.service

将下列配置加到docker.service中并保存

[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

4、启动

chmod +x /etc/systemd/system/docker.service             #添加文件权限并启动docker

systemctl daemon-reload                                                       #重载unit配置文件

systemctl start docker                                                             #启动Docker

systemctl enable docker.service                                           #设置开机自启

5、验证

systemctl status docker                                                         #查看Docker状态

docker -v                                                                                     #查看Docker版本

修改docker挂载路径：

1、确保停止docker服务

# systemstl stop docker.service

2、修改/etc/docker/daemon.json文件值，文件不存在需手动创建

# vim /etc/docker/daemon.json

新增以下信息：

{"data-root": "/opt/docker/data"}

3、启动docker服务# systemstl start docker.service

4、docker info 验证Docker Root Dir的值 是否已修改为/opt/docker/data
