linux安装docker和docker-compose

一. 卸载docker

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

二. 安装docker

1. 安装依赖包

yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

2. 设定仓库

yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

3. 安装稳定docker引擎

yum install docker-ce docker-ce-cli containerd.io

4. 启动docker

systemctl start docker

三. 安装docker-compose

1. 获取最新稳定版

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2. 授予权限

sudo chmod +x /usr/local/bin/docker-compose

3. 创建link

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

四. 修改镜像和配置文件

1. 修改daemon.json

vim /etc/docker/daemon.json

2. 修改daemon.json

{
  "registry-mirrors": ["https://"], #个人阿里云进行加速地址
  "data-root": "/usr/local/docker-continer" #镜像存放地址
  "log-driver": "json-file",
  "dns": ["223.5.5.5","202.93.128.86"], #DNS解析机器
  "log-opts": {
    "max-size": "5m",
    "max-file": "3"
  }
}

3. 重启docker

$ systemctl daemon-reload
# 重启docker守护进程
$ systemctl restart docker
