二、解决办法

1）RPM包安装，适合CentOS、RHEL和SUSE Linux等操作系统：

1.远程连接Linux实例。
2.运行wget https://repo-aliyun-assist.oss-cn-beijing.aliyuncs.com/download/aliyun_assist.rpm下载云助手客户端rpm包
3.运行rpm -ivh aliyun_assist.rpm安装云助手客户端。
（仅经典网络类型实例）在云助手的安装目录下创建名为region-id的文件，在文件中填入ECS实例所属地域的ID，例如cn-hangzhou。更多取值请参见地域和可用区。

4.验证是否安装成功

　　aliyun-service -v

注意：

第3步，对于经典网络类型实例，需要在安装目录下创建名为region-id的文件

1.默认安装路径:

　　如果您选择默认安装路径，则客户端在Linux实例中的安装目录为：

• CoreOS操作系统：/opt/local/share/aliyun-assist/
• 其他操作系统（Ubuntu、Debian、Red Hat、SUSE Linux Enterprise Server、OpenSUSE和Aliyun Linux等）：/usr/local/share/aliyun-assist/

2.查找ECS实例所属地域的ID
