1.API函数查询

      http://github.com.redis/hiredis

 2.2编译
     添加环境变量
     
     
     
 2.3运行  
       ./a.out                   直接运行
       redis-cli get itcast  客户端运行


 2.4 文件编写

int mainset()
{
  redisContext *pr=redisConnect("127.0.0.1",6379);        //1.连接
  if(pr!=NULL)
  {
     redisReply *reply=redisCommand(pr,"set it%s ","abc"); //2.发命令 命令行里发送的
     freeReplyObject(reply);                               //3.销毁object
     reply=redisCommand(pr,"get itcase");
     puts(reply->str);
     freeReplyObject(reply);  
     
  }
}


int mainget()
{
  redisContext *pr=redisConnect("127.0.0.1",6379);       //1.连接
  if(pr!=NULL)
  {
     redisReply *reply=redisCommand(pr,"set it%s ","abc");//2.发命令 命令行里发送的
     freeReplyObject(reply);                              //3.销毁object
     reply=redisCommand(pr,"get itcase");
     puts(reply->str);
     
  }
}
