1、使用 apt-get
# Add the Docker repository key to your local keychain
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
# Add the Docker repository to your apt sources list.
sudo sh -c "echo deb https://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
# update your sources list
sudo apt-get update
# install the latest
sudo apt-get install lxc-docker
2、手工安裝
# kill the running docker daemon
killall docker
# get the latest binary
wget http://get.docker.io/builds/Linux/x86_64/docker-latest -O docker
# make it executable
chmod +x docker
# start the new version -d是指以守護(hù)進(jìn)程的方式執(zhí)行， 指在后臺(tái)執(zhí)行
sudo ./docker -d
升級(jí)的一次實(shí)際操作記錄：
# docker ps 查看運(yùn)行中的docker容器進(jìn)程
[root@AY140716133600881bf5Z ~]# docker ps
