localhost是本地主机的意思也就是当前使用的这台计算机

启动redis服务的命令是下面这个：

#./bin/redis-server redis.conf

http://img1.sycdn.imooc.com//climg/5fa3d0a509c6e07a04340072.jpg

使用守护进程的方式开启的话你可以先备份一下配置文件，还需要在里面开启进程，配置ip等，最后指定配置文件去以守护进程方式启动。你参考这个看看：

帮助到你的话，记得给我点个采纳~

同学你好，根据报错信息Connection refused: no further information:localhost/127.0.0.1:6379连接本机Redis失败，其中localhost是本机地址

http://img1.sycdn.imooc.com//climg/5fa3bf8a09105c3207680191.jpg

这里同学检查一下redis服务是否启动，ip和端口号是否正确。如果redis服务启动，并且ip和端口号正确，建议同学关闭防火墙再试试。

启动Redis并关闭防火墙，参考命令如下：

#./bin/redis-server redis.conf 
# systemctl stop firewalld.service

    1怎么开起来着，每次使用都要重新开启吗？能不能挂在服务器上 2怎么使用守护进程的方式开启，可以使用命令简单演示一下吗
