5.Redis容器启动了，那接下来怎么办？ 办法：把putty关了，然后从新进来putty
6. 怎么进入容器呢？ 先安装NSenter：
cd /tmp; curl http://ftp.sjtu.edu.cn/sites/ftp.kernel.org/pub/linux/utils/util-linux/v2.25/util-linux-2.25.tar.gz | tar -zxf-; cd util-linux-2.25; sudo apt-get install build-essential sudo apt-get make ./configure --without-ncurses make nsenter && sudo cp nsenter /usr/local/bin
方法一：
PID=$(docker inspect --format "{{ .State.Pid }}" <container>)
nsenter --target $PID --mount --uts --ipc --net --pid
方法二：
安装脚本（脚本参照：https://github.com/jpetazzo/nsenter/blob/master/docker-enter）
wget -P ~ https://github.com/yeasy/docker_practice/raw/master/_local/.bashrc_docker;
echo "[ -f ~/.bashrc_docker ] && . ~/.bashrc_docker" >> ~/.bashrc; source ~/.bashrc
最后，调用docker-enter进入容器：
root@jumping:/tmp# docker-enter b430d6f4ff00 ls dirname: invalid option -- 's' Try 'dirname --help' for more information. bin boot data dev entrypoint.sh etc home lib lib64 media mnt opt proc root run sbin selinux srv sys tmp usr var root@b430d6f4ff00:~#
注：这里大家看到有错误，是因为脚本中用到(dirname "
7. 测试redis命令 进入容器后可以用redis-cli ping测试可以连接上本机刚才启动的redis-server不，返回PONG说明连接成功。
直接按redis-cli进入redis 命令测试下可以用不：
root@816ebd247014:~# redis-cli ping PONG root@816ebd247014:~# redis-cli 127.0.0.1:6379> set myname jumping OK 127.0.0.1:6379> get myname "jumping" 127.0.0.1:6379>
8. 这样就简单的把redis启动起来了，要用起来大家还要把端口影射到宿主机器上，然后可以通过客户端来调用Redis:http://redis.io/clients
