cURL是一个命令行工具，通过不同的协议传输数据，1997年首次发布。cURL is a computer software project providing a library and command-line tool for transferring data using various protocols. The cURL project produces two products, libcurl and cURL. It was first released in 1997. The name originally stood for “see URL”.curl支持的协议有FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, POP3, IMAP, SMTP and RTSP at the time of this writing. Wget支持HTTP, HTTPS and FTP三种协议.

可将以上代码写入Shell脚本，执行即可。

添加服务

以上步骤完成后，重新到Ambari UI界面添加Ambari Metrics服务即可。如果哪个服务实在无法修复，最无奈的方法，重装此服务。
