在线安装 docker 与docker-compose

1.升级pip 或者是升级pip3 

使用下面哪一种都行。

# 升级pip:
1.sudo wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
2.sudo python get-pip.py
3.pip -V

# 升级pip3:
1.sudo wget https://bootstrap.pypa.io/pip/3.5/get-pip.py
2.sudo python3 get-pip.py
3.pip -V

2.一行命令即可在线安装 

yum install -y yum-utils device-mapper-persistent-data lvm2 \
&& yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo \
&& yum install  -y docker-ce docker-ce-cli containerd.io \
&& systemctl start docker \
&& yum -y install epel-release \
&& yum -y install python-pip \
&& pip install --upgrade pip \
&& pip install docker-compose

3.卸载docker 

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

5.第二种安装方式

安装docker服务
命令行输入curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun即可快速安装

如提示curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to get.docker.com:443错误则需按照下面的操作

Ubuntu 系统下操作: apt-get install libnss3

Centos 系统下操作: yum install nss && yum update nss

执行完安装nss步骤后再次执行curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun即可

–mirror Aliyun: 代表使用阿里云源

如果不想安装nss也可以在浏览器打开https://get.docker.com,然后把内容保存为install_docker,在执行bash -s install_docker --mirror Aliyun即可

6.安装docker-compose

1.# 官方地址，可能比较慢【不推荐】

# 下载路径是【/usr/local/bin/】下载完之后可以看下【/usr/local/bin】这个目录有没有【docker-compose】文件
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2.# 国内镜像地址【推荐】

# 下载路径是【/usr/local/bin/】下载完之后可以看下【/usr/local/bin】这个目录有没有【docker-compose】文件
curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
2、授权

# 给docker compose 目录授权
sudo chmod +x /usr/local/bin/docker-compose
3、测试是否安装成功

docker-compose version
docker-compose --version
