Linux下Docker 离线安装详细步骤,亲测成功

1.离线原因：公司新创不能使用开元linux，使用了一个变种centOS，致使yum被禁

2.步骤：

2.1 下载docker tar包，下载地址：Index of linux/https://download.docker.com/linux/ 2.2 新建自己的软件目录，然后将tar移过去，并解压

 mv docker-24.0.6.tgz  /gdc/app/docker24.0.6/
 tar xzvf docker-24.0.6.tgz

2.3将解压文件中docker下的所有文件移动到/usr/bin/下

 sudo cp docker/* /usr/bin/

2.4修改/etc/systemd/system/docker.service内容（没有的话vi命令会自动创建该文件）

[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

2.5 添加启动权限

chmod +x /etc/systemd/system/docker.service

2.6创建docker配置文件,并添加daemon.json的配置内容（docker下载的存储地址）

mkdir -p /etc/docker
touch /etc/docker/daemon.json
vi /etc/docker/daemon.json

下面 data-root 位置比较重要放的位置上不对可能导致磁盘空间不够，尽量不要放到/HOME
下
{
    "data-root": "/gdc/app/docker24.0.6/docker-data",
"registry-mirrors": [
"https://rnv4c7zq.mirror.aliyuncs.com",
   "http://hub-mirror.c.163.com",
   "https://docker.mirrors.ustc.edu.cn"
  ]
}

2.7启动


systemctl daemon-reload  --配置重载
systemctl start docker    --启动
systemctl enable docker  --开机启动
systemctl status docker  --查看状态
docker info    --概要
docker images  --已经下载的镜像
docker pull 镜像名字[:TAG]    --镜像名字：版本号 不写TAG就是最新版
docker system df   查看镜像/容器/数据卷所占的空间
docker rmi  -f 镜像ID    删除某个镜像ID
docker exec -it elasticsearch /bin/bash  --打开 es的容器空间（这是我本机的容器名称）

sudo groupadd docker    创建docker分组
sudo usermod -aG docker $USER    将当前用户加入分组
newgrp docker  # 更新用户组docker

docker info | grep "Docker Root Dir"   显示docker数据文件位置，docker迁移位置完成后检测迁移生效使用

2.8成功截图附上,已更新ES搜索引擎及 kibana以及ik分词器在docker中的安装和配置,接为亲测；
