一、CentOS 7.8 安装Docker
1.1、安装需要的软件包
yum install -y yum-utils device-mapper-persistent-data lvm2
1.12、设置yum源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
1.13、查看仓库中的docker版本
yum list docker-ce --showduplicates | sort -r
1.14、安装docker
yum install -y docker-ce
1.5.配置源加速
mkdir -p /etc/docker
vi /etc/docker/daemon.json
{
"registry-mirrors" : [
"https://8xpk5wnt.mirror.aliyuncs.com"
]
}
1.6.设置开机自启
systemctl enable docker
systemctl daemon-reload
1.7.启动docker
sudo systemctl start docker # 启动docker服务
sudo systemctl stop docker # 停止docker服务
sudo systemctl restart docker # 重启docker服务
1.8.查看docker信息
docker info
# docker 版本查看
docker -v
二、卸载
yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine docker-ce
三、安装Docker-Compose
sudo curl -L https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
#慢的话可以用这个
sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
