NFS 安裝問題解決

開始使用這個：

mount -t nfs 192.168.119.138:/root/work /share

報錯：

 cat /var/log/messages | grep mount

Nov  4 15:16:09 air02 rpc.mountd[19139]: Caught signal 15, un-registering and exiting.

Nov  4 15:16:34 air02 rpc.mountd[19206]: Version 1.2.7 starting

換成這個ok：mount -t nfs air02:/root/work /share

輔助：

1. 使用的命令：

yum install portmap nfs-utils

service nfs start

exportfs -a

service nfs restart

service nfs start.若是在啓動以後須要修改exports,能夠exportfs -rv從新輸出.
