    ntpdate更新系统时间时报错Can't find host ntp1.aliyun.com: Servname not supported for ai_socktype (-8)

    所报错误:

    [root@web01 ~]# ntpdate ntp1.aliyun.com
    
    Error resolving ntp1.aliyun.com: Servname not supported for ai_socktype (-8)
    
    11 Feb 20:58:03 ntpdate[3318]: Can't find host ntp1.aliyun.com: Servname not supported for ai_socktype (-8)
    
    11 Feb 20:58:03 ntpdate[3318]: no servers can be used, exiting

    原因:/etc/services 文件被改动或者不存在 导致域名解析错误

    [root@web01 etc]# ls -l servic*
    
    -rw-r--r--. 1 root root  10240 Feb 11 02:27 services
    
    -rw-r--r--  1 root root 641020 Feb 11 02:22 services.bak  长格式对比后发现源文件已改动
    
    [root@web01 etc]# mv services /tmp
    
    [root@web01 etc]# ls -l servic*
    
    -rw-r--r-- 1 root root 641020 Feb 11 02:22 services.bak
    
    [root@web01 etc]# mv services.bak  services
    
    [root@web01 etc]# ls -l servic*
    
    -rw-r--r-- 1 root root 641020 Feb 11 02:22 services
    
    [root@web01 etc]# ntpdate ntp1.aliyun.com
