需要linux内核版本在3.10以上,可以通过uname -r查看。
安装docker-ce
1、切换为root用户
2、卸载旧版本(如果安装过旧版本的话)
yum remove -y docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
3、安装需要的软件包
# yum-util 提供 yum-config-manager 功能
# 另外两个是 devicemapper 驱动依赖的
yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
4、设置yum源
由于官网的源太慢了,这里可以使用阿里云Docker Yum源替代:
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo yum makecache fast
5、安装最新版本docker
yum install -y docker-ce
1
6、启动docker
systemctl start docker.service
1
7、设置开机自启动
systemctl enable docker.service
1
8、验证安装是否成功(有client和service两部分表示docker安装启动都成功了)

安装docker-compose
github的地址下载太慢了,国内可以使用http://get.daocloud.io/#install-compose网站上面的地址。
首先下载docker-compose:
curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
1
然后赋权限:
chmod +x /usr/local/bin/docker-compose
1
最后查看版本:
docker-compose -v
