Docker - 离线安装 docker 、docker-compose

环境：centos8 , docker25

 

一. 安装 Docker 

 

1. 安装包官方地址：https://download.docker.com/linux/static/stable/x86_64/

 

 

2.解压

代码如下（示例）：

tar -zxvf docker-18.06.3-ce.tgz

 

 

3.将解压出来的docker文件复制到 /usr/bin/ 目录下

注：不可修改目录，其中runc文件如已存在可不复制，或提前备份好再复盖。

代码如下（示例）： 

cp docker/* /usr/bin/

 

 

 

4.创建 docker.service文件

进入/etc/systemd/system/目录,并创建docker.service文件，内容如下，这样可以将docker注册为service服务

代码如下（示例）： 

[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 --selinux-enabled=false --insecure-registry=127.0.0.1
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

 

 此处的–insecure-registry=127.0.0.1（此处改成你私服ip）设置是针对有搭建了自己私服Harbor时允许docker进行不安全的访问，否则访问将会被拒绝。

 

5.启动docker

给docker.service文件添加执行权限 

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

 

 

重新加载配置文件（每次有修改docker.service文件时都要重新加载下） 

systemctl daemon-reload

 

 

启动

systemctl start docker

 

设置开机启动

systemctl enable docker.service

 

查看docker服务状态 

systemctl status docker

上图表示docker已安装成功

二. 安装 docker-compose

 

1. 下载docker-compose

官方地址：https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-linux-x86_64

 

 

2.安装
sudo mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose -v

 

 

查看版本 docker-compose version 

[root@centos247 docker]# docker-compose version
docker-compose version 1.24.1, build 4667896b
docker-py version: 3.7.3
CPython version: 3.6.8
OpenSSL version: OpenSSL 1.1.0j  20 Nov 2018

 

 

三. 在线安装 
curl -sSL https://get.daocloud.io/docker | sh

 

四.docker挂载目录更改
4.1 首次安装 
vi /etc/docker/daemon.json
# 内容如下：,具体目录试自己情况而定
{
  "data-root": "/mnt/run/docker"
}

 

重启 systemctl restart docker

4.2 已有运行容器

如果已经有容器进行运行了，此时需要创建好具体盘符的目录，使用如下命令进行将容器拷贝到新盘里

cp -R /var/run/docker /mnt/run

再修改目录

vi /etc/docker/daemon.json

# 内容如下：,具体目录试自己情况而定
{
  "data-root": "/mnt/run/docker"
}

 

重启 

systemctl restart docker

 

最后提供一些daemon.json文件内容：

{
  "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2",
  "data-root": "/home/run/docker"
}

 

 

如遇到docker容器中域名访问不到，但ip可以访问的问题
