[Docker心得]在Centos6與Centos7安裝的差異比較

到目前為止,如果使用Centos7安裝Docker記得images使用cnetos6的版本會比較好一點,光卡在systemctl上就能卡很久了,待續.

1.Centos6安裝步驟

1.1首先要安裝上EPEL後才能安裝Docker,所以6以後的版本就不建議玩Docker了.

sudo wget http://download.fedoraproject.org/pub/epel/4/x86_64/epel-release-4-10.noarch.rpm

1.2下載完RPM檔後,就安裝了.

sudo rpm -ivh epel-release-4-10.noarch.rpm

1.3安裝完RPM檔後一定要更新.

sudo yum repolist

1.4接著移除Centos6上的docker(這步必要不管是剛剛裝完OS,或是舊有版本安裝docker).

sudo yum -y remove docker

1.5安裝Docker.

sudo yum install docker-io

1.6啟動Docker服務.

sudo service docker start

1.7設定Docker服務常駐.

sudo chkconfig docker on

2.Centos7安裝步驟

2.1安裝Docker.

sudo yum -y install docker docker-registry

2.2常駐Docker服務.

sudo systemctl enable docker.service

2.3啟動Docker.

sudo systemctl start docker.service

Centos7三步驟就收工,當然記得安裝完後確認一下Docker的版本.

sudo docker version

如果想玩目前最新支援ipv6的1.5版,記得更新.

sudo systemctl stop docker 

sudo wget https://get.docker.com/builds/Linux/x86_64/docker-latest -O /usr/bin/docker

sudo systemctl start docker
