在redhat 6.6上安装Docker

安装环境

支持Docker的RHEL版本

Red Hat Enterprise Linux 7 (64-bit)
Red Hat Enterprise Linux 6.5 (64-bit) 或更高版本123

不论是RHEL的哪个版本，Docker都要求是64位的安装环境。RHEL 6的内核版本必须是2.6.32-431或者更高。查看内核版本：

# uname -r12

安装docker

安装前的准备

1.安装libcgroup（该软件包提供了一系列工具和库文件用于控制和管理控制组）

# rpm -ivh libcgroup-0.40.rc1-6.el6_5.1.x86_64.rpm12

libcgroup软件包下载地址：ftp://mirror.switch.ch/pool/4/mirror/scientificlinux/6.5/x86_64/updates/fastbugs/libcgroup-0.40.rc1-6.el6_5.1.x86_64.rpm

2.更新yum源

# rpm -ivh epel-release-latest-6.noarch.rpm12

epel-release-latest软件包下载地址：https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

安装docker-io

1.使用yum软件包管理器安装docker-io：

# yum install docker-io

2.启动docker服务：

# service docker start
Starting cgconfig service:                                 [确定]
Starting docker:                                       [确定]1234

3.确认docker服务是否运行：

# service docker status
docker (pid  2593) 正在运行...123

其他一些事项

开机启动docker守护进程

安装docker-io软件包时已创建docker服务默认开机项：

# ls -l /etc/rc5.d/S95docker 
lrwxrwxrwx. 1 root root 16 8月  31 2015 /etc/rc5.d/S95docker -> ../init.d/docker123

备注： redhat 6.6的默认启动级别是5。

docker版本

使用yum默认配置的源安装的docker版本是1.7.1：

# docker version
Client version: 1.7.1
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 786b29d/1.7.1
OS/Arch (client): linux/amd64
Server version: 1.7.1
Server API version: 1.19
Go version (server): go1.4.2
Git commit (server): 786b29d/1.7.1
OS/Arch (server): linux/amd64123456789101112

升级docker

# yum update docker-io
