Cent7安装docker和docker-compose

一. 安装docker

1.1 卸载已经安装的Docker

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

rm -rf /etc/systemd/system/docker.service.d

rm -rf /var/lib/docker

rm -rf /var/run/docker

1.2 添加阿里镜像

# Set up repository
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# Use Aliyun Docker
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

1.3 查看可以安装的docker版本

yum list docker-ce --showduplicates

1.4 安装18.03.1

sudo yum -y install docker-ce-18.03.1.ce

1.5 启动 Docker，设置开机启动

systemctl enable docker
systemctl start docker

1.6 设置Docker阿里云加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://x83mabsk.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

二. 在Linux系统上安装Compose

2.1 运行此命令以下载Docker Compose的当前稳定版本：

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

要安装不同版本的Compose，请替换1.24.0 为要使用的Compose版本。

2.2 对二进制文件应用可执行权限：

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

2.3 测试安装

[root@wanfei docker]# docker-compose --version
/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.24.1) or chardet (2.2.1) doesn't match a supported version!
  RequestsDependencyWarning)
docker-compose version 1.24.0, build 0aa5906

出现RequestsDependencyWarning警告，urllib3 (1.24.1) or chardet (2.2.1)版本不匹配!

2.4 解决办法，卸载urllib3 和chardet

sudo pip uninstall urllib3
sudo pip uninstall chardet

2.5 然后，再安装requests

sudo pip install requests

[root@wanfei docker]# docker-compose --version
docker-compose version 1.24.0, build 0aa5906
