redhat安装docker

一、禁用selinux 由于Selinux和LXC有冲突，所以需要禁用selinux。编辑/etc/selinux/config，设置两个关键变量。 SELINUX=disabled SELINUXTYPE=targeted

二、配置Fedora EPEL源 1 sudo yum install http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
三、添加hop5.repo源

cd /etc/yum.repos.d sudo wget http://www.hop5.in/yum/el6/hop5.repo
四、安装Docker sudo yum install docker-io

图1是yum安装过程中的截图，可以发现安装的软件只有docker和lxc相关包，没有内核包，例如kernel-ml-aufs。



图1 yum install docker-io输出截图

五、初步验证docker 输入docker -h，如果有如下输出，就证明docker在形式上已经安装成功。

# docker -h Usage of docker: -D=false: Enable debug mode -H=[]: Multiple tcp://host:port or unix://path/to/socket to bind in daemon mode, single connection otherwise -api-enable-cors=false: Enable CORS headers in the remote API -b="": Attach containers to a pre-existing network bridge; use 'none' to disable container networking -bip="": Use this CIDR notation address for the network bridge's IP, not compatible with -b -d=false: Enable daemon mode -dns=[]: Force docker to use specific DNS servers -g="/var/lib/docker": Path to use as the root of the docker runtime -icc=true: Enable inter-container communication -ip="0.0.0.0": Default IP address to use when binding container ports -iptables=true: Disable docker's addition of iptables rules -p="/var/run/docker.pid": Path to use for daemon PID file -r=true: Restart previously running containers -s="": Force the docker runtime to use a specific storage driver -v=false: Print version information and quit
