阿里云主机ECS部署项目报：ERROR: cant resolve localhost address

一、我在阿里云买了个云主机ECS，在上面部署了一个Redis，并开启了远程连接，我在本地，通过IP+端口+用户名+密码，远程连接到Redis是一点问题都没有的。

二、现在我将项目部署到阿里云主机上去了。  
我在启动项目的时候，一直给我报一个错误：

[2018-05-04 15:50:04] ERROR: cant resolve localhost address
    java.net.UnknownHostException: iZbp17cj14ulhfrlj02rkaZ: iZbp17cj14ulhfrlj02rkaZ: Name or service not known

    说的是主机名无法解析。

三、首先查看Linux的主机名

root@iZbp17cj14ulhfrlj02rkaZ:~# hostname
    iZbp17cj14ulhfrlj02rkaZ
    root@iZbp17cj14ulhfrlj02rkaZ:~#

四、编辑/etc/hosts

root@iZbp17cj14ulhfrlj02rkaZ:~# vi /etc/hosts

五、将主机名添加到localhost后面  
![这里写图片描述][70]

六、再次启动，成功。
