centos 7 安装docker
1.首先配置安装源:
打开文件/etc/yum.repos.d/docker.repo
插入以下内容:
[docker-repo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
2.安装docker
yum install docker-engine
这一步可能会报错:
Error: Package: docker-ce-18.03.1.ce-1.el7.centos.x86_64 (docker-ce-edge)
Requires: container-selinux >= 2.9
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
----------------------------------------------------------------------------------------------------------------
container-selinux >= 2.9
这个报错是container-selinux版本低或者是没安装的原因
yum 安装container-selinux 一般的域名源又找不到这个包
需要安装epel源 才能yum安装container-selinux
然后在安装docker-ce就可以了。
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install epel-release #阿里云上的epel源
然后yum install container-selinux
3.安装完成后启动docker,并设置开机自启动
systemctl start docker.service
systemctl enable docker.service
