1.获取docker安装包
wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz
2. 解压
tar -zxvf docker-18.06.3-ce.tgz
3.将解压文件放到/usr/bin/
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
[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 $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel. We recommend using cgroups to do container-local accounting. LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity # Uncomment TasksMax if your systemd version supports it. # Only systemd 226 and above support this version. #TasksMax=infinity TimeoutStartSec=0 # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process # restart the docker process if it exits prematurely Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target
# 此处的–insecure-registry=127.0.0.1（此处改成你私服ip）设置是针对有搭建了自己私服Harbor时允许docker进行不安全的访问，否则访问将会被拒绝。
5. 启动
# 给docker.service文件添加执行权限
chmod +x /etc/systemd/system/docker.service
# 重新加载配置文件（每次有修改docker.service文件时都要重新加载下）
systemctl daemon-reload
# 启动 systemctl start docker
# 设置开机启动 systemctl enable docker.service
# 查看docker服务状态
[root@localhost system]# systemctl status docker
安装docker-compose
# docker-compose下载并放到/usr/local/bin/下面：
curl -L "https://github.com/docker/compose/releases/download/v2.18.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# 下载好docker-compose的前提下，拷贝到指定位置
sudo cp docker-compose /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
docker-compose -v
# 最后使用 docker-compose -v 命令测试是否安装成功（如果提示“没有那个文件或目录”可以重启下服务器再试试）
