Linux: clnt_create: RPC: 程序未注册

NFS 安装最近自动卸载。当我检查时，NFS 服务状态显示为正在运行。

[root@hsluasrepo]# service nfs status
rpc.svcgssd is stopped
rpc.mountd (pid 4083) is running...
nfsd (pid 4148 4147 4146 4145 4144 4143 4142 4141) is running...
rpc.rquotad (pid 4079) is running...

[root@hsluasrepo]# service rpcbind status
rpcbind (pid  4203) is running...

[root@hsluasrepo common]# rpcinfo -p 10.80.3.154
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper

但showmount输出显示错误。

[root@hsluasrepo ]# showmount -e 10.80.3.154
clnt_create: RPC: Program not registered

重新启动 NFS 服务后，showmount输出显示 NFS 服务器的导出列表。

谁能告诉我这个问题的根本原因以及将来如何避免这个问题？

你必须：

[email protected]]$ service nfs status
rpc.svcgssd is stopped
rpc.mountd is stopped
nfsd is stopped
rpc.rquotad is stopped

[email protected]]$ service nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS quotas:                                       [  OK  ]
Starting NFS daemon:                                       [  OK  ]
Starting NFS mountd:                                       [  OK  ]

[email protected]]$ chkconfig nfs on

我在 RHEL6 上遇到了这个问题。这很奇怪，但是service rpcbind restart在 nfs 服务之前运行使错误消失了。我关注了这篇文章：在RHEL6中逐步配置NFS服务器

这对我有用，但我仍然想知道其背后的原因。谁能解释一下吗？

答案3

我遇到了这个问题，并使用一种简单的方法解决了 nfs 服务器和客户端配置，它涉及 10 个步骤。

  1. 安装 nfs-utils 并检查以确保其已安装 ( yum install -y nfs-utils / rpm -qa | grep nfs-utils)
  2. vi /etc/sysconfig/nfs（取消注释并更改以下端口号.. STATD_PORT=、MOUNTD_PORT=、LOCKD_UDPPORT=、LOCKED_TCPPORT={您可以使用 4000-4004 或您选择的任何端口}
  3. system-config-firewall-tui{打开上面2中指定的端口号以及111（rpc）和2049（nfs）}
  4. iptables save
  5. vi /etc/export（提供要共享的目录、共享位置以及选项，例如。/share *(ro,async)
  6. exportfs -rv
  7. service nfs start
  8. ssh root@clientserver。例如。ssh [email protected]
  9. showmount -e {master ip}例如。showmount -e 192.168.2.31
  10. mount -t nfs {master ip}:/{shared dir from master} /{mount point}..例如。mount -t nfs 192.168.2.31:/share /mnt

最后，做一个df -h.

这只是我的一点贡献；我可能没有采取所有必要的步骤，但这可能会有所帮助。

我最近在虚拟机上的 RHEL 中配置了 NFS，当我设置 showmount -e localhost 命令时，出现了同样的问题。尝试重新启动服务几次后，我只是关闭虚拟机并再次启动，问题就解决了。

问候！！
