Windows

安装docker

在win10下安装docker可以直接安装Docker for Windows Installer.exe，但是得把Hyper-V打开，有时候Hyper-V可能会抽风，docker就运行不了——我是从1709更新到1803的，但是在1803下docker一直无法在Linux container下启动，而在这个模式下才可以直接Pull redis，所以我只好把win10往回恢复到1709。嗯，目前是可以用的。

至于win7则需要先DockerToolbox.exe，具体的过程还得再win7装了才知道。

使用docker开启redis

在docker里用“docker pull redis”把redis镜像安装好。运行docker里的镜像会比较占容量，可以通过windows自带的Hyper-V 管理器可以设置虚拟硬盘和虚拟机的路径到非系统盘。

设置好路径后，docker里的Disk image location会自动设置好，其实切换到Linux Container 下，memory的大小不一定要是1280MB（windows下docker使用及注意事项），proxies里面可以设置合适的代理加快下载速度，目前还没需要就没有设置，菜鸟教程里给的是网易的镜像地址（http://hub-mirror.c.163.com）。这样就基本设置好了。

开启Powershell，在里面直接输入docker run -d -p 6379:6379 --name redis00 redis，就可以开启一个redis容器。

上述命令行的部分解释如下：-d表示在后台运行，不阻塞命令行界面，让我们可继续输入其它命令，是detach单词缩写。

-p 表示端口号，左边的6379表示win10系统的端口（自已换其它的也随便），右边的则表表容器中redis端口,并且似乎右边这个必须要设置为6379，虽然可以设置成功，但是在使用这个redis容器的时候会出现错误（Error: Server closed the connection）。

--name表示运行redis镜像的一个实例名称。听别人打过一个比方，把镜像比作一个类，而运行一个镜像就相当于实例化一个对象。

再开启一个redis容器：docker run -d -p 7000:6379 --name redis01 redis.

 

可见，以上默认的IP地址（系统的）均为0.0.0.0，其实docker里可以自己设置IP地址：docker run -d -p 127.0.0.1:7001:6379 --name redis02 redis

有时在创建或开启已创建的redis容器时会出现以下错误：

这应该是机器上已经用了这个IP地址，换一个IP试试。

Docker一些常用的命令

docker ps：列出正在工作的容器

docker ps -a：列出所有的容器

docker ps -l：列出最近建立的容器，包括停止运行的

docker start 容器名：启动容器

docker stop 容器名：暂停容器

docker rm 容器名：移除容器

docker pause 容器名：暂停容器中所有的进程

几个需要注意的：

pause

docker pause可以暂时停止容器，以释放一部分CPU出来给其他服务使用
docker unpause可以解冻

docker stop vs kill

stop会首先尝试正常结束容器(发送SIGTERM信号给容器中的程序)，如果程序没有响应的话，则强制结束容器(发送SIGKILL信号)；

kill则会直接强制结束容器

其他的可以参考：http://www.runoob.com/docker/docker-command-manual.html

Ubuntu

#2018年10月27号

#新增Ubuntu的使用方法

首先安装docker，依次在终端执行以下命令，就可以完成基本的docker安装，至少可以使用pull镜像了，更多的docker安装方法可以参考网络搜索。

sudo apt-get install docker
sudo apt-get install docker.io

然后安装redis

sudo docker pull redis

安装redis镜像之后，便可以在docker中创建redis容器，格式跟Windows下的一样。

sudo docker run -d -p 6379:6379 --name redis00 redis

然后执行以下命令就可以进入redis容器：

sudo docker exec -it redis00 redis-cli
