------------------------------------------------------------------------------------
Centos7安装docker
yum update
# vim /etc/yum.repos.d/docker.repo
//添加以下内容
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
# yum install docker-engine -y
如果安装时候遇到报错如下
yum install 出现 Transaction Check Error:
给出centos7下的卸载docker的命令
yum list installed | grep docker
yum -y remove 上述命令下的输出结果如
[root@VM_116_112_centos lib]# yum list installed | grep docker
docker.x86_64 1.10.3-46.el7.centos.14 @extras
docker-common.x86_64 1.10.3-46.el7.centos.14 @extras
docker-selinux.x86_64 1.10.3-46.el7.centos.14 @extras
yum -y remove docker.x86_64
yum -y remove docker-common.x86_64
yum -y remove docker-selinux.x86_64
就OK了
卸载成功之后 重新执行
# yum install docker-engine -y
安装完毕 启动docker
systemctl start docker
