一.系统要求
Docker的安装，需要在CentOS 7.0+版本，内核至少3.10，64-bit
uname --r
[randy@randysun ~]$ uname --r 3.10.0-514.6.2.el7.x86_64 [randy@randysun ~]$
二.更新YUM
yun update
三.新建Docker repository
在 /etc/yum.repos.d/下新建一个文件docker.repo，内如如下
[dockerrepo] name=Docker Repository baseurl=https://yum.dockerproject.org/repo/main/centos/7 enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg
四.安装
[root@randysun yum.repos.d]# yum install docker-engine Loaded plugins: fastestmirror Repository base is listed more than once in the configuration Repository updates is listed more than once in the configuration Repository extras is listed more than once in the configuration Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package docker-engine.x86_64 0:17.05.0.ce-1.el7.centos will be installed --> Processing Dependency: docker-engine-selinux >= 17.05.0.ce-1.el7.centos for package: docker-engine-17.05.0.ce-1.el7.centos.x86_64 --> Processing Dependency: libcgroup for package: docker-engine-17.05.0.ce-1.el7.centos.x86_64 --> Processing Dependency: libseccomp.so.2()(64bit) for package: docker-engine-17.05.0.ce-1.el7.centos.x86_64 --> Processing Dependency: libltdl.so.7()(64bit) for package: docker-engine-17.05.0.ce-1.el7.centos.x86_64 --> Running transaction check ---> Package docker-engine-selinux.noarch 0:17.05.0.ce-1.el7.centos will be installed --> Processing Dependency: policycoreutils-python for package: docker-engine-selinux-17.05.0.ce-1.el7.centos.noarch ---> Package libcgroup.x86_64 0:0.41-11.el7 will be installed ---> Package libseccomp.x86_64 0:2.3.1-2.el7 will be installed ---> Package libtool-ltdl.x86_64 0:2.4.2-22.el7_3 will be installed
