一、在windows中安装redis数据库
1、在Windows上安装Redis,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
