Windows上使用C#访问ubuntu上的redis数据库

一、在win中安装redis数据库

1、在windows上安装Redis,由于博客园不支持上传msi文件，所以我把后缀改为了rar,下载下来的时候别忘了将rar改为msi，安装的时候把加入到环境变量勾选上。
2、安装好后，win+r打开运行输入cmd进入控制台程序，直接输入redis-cli并且输入ping，回复pong则链接成功，

1、简单字符串存取
set key value
get key
···

3、安装RedisStudio，redis管理界面，个人觉得最好使用的。

二、在ubuntu中安装redis数据库

1、在Vmware中安装Ubuntu虚拟机；
2、安装redis

//下载redis-3.2.6
sudo wget http://download.redis.io/releases/redis-3.2.6.tar.gz
//解压redis-3.2.6
sudo tar -zxvf redis-3.2.6.tar.gz

3、在~/下新建一个redis文件夹并且将redis-3.2.6下的文件全部拷贝进该redis文件夹下

//如果没有安装gcc
sudo apt-get install gcc
//进入redis文件夹执行make
sudo make
sudo make install

4、此时就将redis安装到了/usr/local/bin（服务端，客户端都在里面启动）下了

//进入/usr/local/bin文件夹中
cd /usr/local/bin
//启动redis-server
redis-server ~/redis/redis.conf
redis-cli

5、为了能在我们的win中访问linux下的redis，我们还需要对redis.conf进行少量的更改

protected-mode yes  --> protected-mode no
bind 127.0.0.1      --> #bind 127.0.0.1

6、在终端输入ifconfig，查看ubuntu的IP地址 inet addr:xxx.xxx.xxx.xxx

三、C#使用redis

1、Nuget安装StackExchange.Redis,程序中加入SeRedisHelper类
