CentOS6安裝docker、docker-compose、docker-enter

1、安裝docker

一、查看CentOS內核版本

uname -r

二、安裝Fedora的EPEL源

yum install http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

三、添加hop5.repo源

wget -O /etc/yum.repos.d/hop5.repo http://www.hop5.in/yum/el6/hop5.repo

四、安裝docker.io

yum install docker-io

問題：

　　一、docker進程沒法啓動，報錯docker dead but subsys locked

rm -rf /var/lock/subsys/docker
rm -rf /var/lib/docker/*
rm -rf /var/run/docker.*

　　二、docker服務沒法識別，報錯docker: unrecognized service

yum remove docker*
vim /etc/yum.repos.d/docker.repo
yum install docker-engine

[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg

　　三、docker版本從1.7.1升級到1.9.1

wget https://get.docker.com/builds/Linux/x86_64/docker-1.9.1
chmod +x docker-1.9.1
mv docker-1.9.1 /usr/bin/docker
service docker restart

2、安裝docker-compose

一、下載最新版docker-compose

curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose 

二、對二進制文件應用賦予可執行權限

chmod +x /usr/local/bin/docker-compose

3、安裝docker-enter

一、安裝docker-enter

docker run --rm -v /usr/local/bin:/target jpetazzo/nsenter
