1.创建docker的yum库 [root@localhost~]# cd /etc/yum.repos.d/ [root@localhostyum.repos.d]# vim docker.repo [dockerrepo] name=DockerRepository baseurl=https://yum.dockerproject.org/repo/main/centos/7 enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg （2）安装docker [root@localhost~]# yum install docker-engine （3）关闭centos7下的firewalld服务并安装iptables-ser [root@localhost~]# systemctl disable firewalld rm'/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service' rm'/etc/systemd/system/basic.target.wants/firewalld.service' [root@localhost~]# yum -y install iptables-services （4）开启iptables服务 [root@localhost~]# systemctl enable iptables ln-s '/usr/lib/systemd/system/iptables.service''/etc/systemd/system/basic.target.wants/iptables.service' [root@localhost~]# systemctl start iptables （5）启动docker服务并设置开机自动启动 [root@localhost~]# systemctl start docker.service [root@localhost~]# systemctl enable docker.service ln-s '/usr/lib/systemd/system/docker.service''/etc/systemd/system/multi-user.target.wants/docker.service' （6）验证docker是否安装成功 [root@localhost~]# docker info Containers:0 Images:0 StorageDriver: devicemapper Pool Name: docker-253:1-50332704-pool Pool Blocksize: 65.54 kB Backing Filesystem: xfs Data file: /dev/loop0 Metadata file: /dev/loop1 Data Space Used: 1.821 GB Data Space Total: 107.4 GB Data Space Available: 7.413 GB Metadata Space Used: 1.479 MB Metadata Space Total: 2.147 GB Metadata Space Available: 2.146 GB Udev Sync Supported: true Deferred Removal Enabled: false Data loop file:/var/lib/docker/devicemapper/devicemapper/data Metadata loop file:/var/lib/docker/devicemapper/devicemapper/metadata Library Version: 1.02.93-RHEL7 (2015-01-28) ExecutionDriver: native-0.2 LoggingDriver: json-file KernelVersion: 3.10.0-229.7.2.el7.x86_64 OperatingSystem: CentOS Linux 7 (Core) CPUs:1 TotalMemory: 1.791 GiB Name:localhost.localdomain ID:2EEQ:3VMI:TIUY:NUHZ:NZMQ:VOD7:YW3K:KZG3:IQZT:XR4Q:G4XJ:TCVM （8）查看安装后的docker版本 [root@localhost~]# docker version Client: Version: 1.8.2 API version: 1.20 Go version: go1.4.2 Git commit: 0a8c2e3 Built: Thu Sep 10 19:08:45 UTC 2015 OS/Arch: linux/amd64 Server: Version: 1.8.2 API version: 1.20 Go version: go1.4.2 Git commit: 0a8c2e3 Built: Thu Sep 10 19:08:45 UTC 2015 OS/Arch: linux/amd64 (责任编辑：IT) |
