NFSv4 設定

最近在設定CentOS 6 的時候發現, NFS default 是用version 4. 不察之下發現設不起來 ><
底下是NFSv4 的設定

CentOS 6時，由於NFS為NFSv4，需多設定一個檔案為/etc/idmapd.conf 還有必須啟動rpcidmapd服務

Head Node

####  vi /etc/idmapd.conf
[General]
Verbosity = 1 #主要更改
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
Domain = snowfox #主要更改
.
. (略)
.
#Local-Realms =
[Mapping]
#Nobody-User = nobody
#Nobody-Group = nobody

然後 將rpcidmapd服務開啟 service rpcidmapd start chkconfig rpcidmapd --level 345 on




Child Node

[General]
Verbosity = 1 #主要更改
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
Domain = snowfox #主要更改
.
. (略)
.
#Local-Realms =
[Mapping]
#Nobody-User = nobody
#Nobody-Group = nobody
[Translation]

將rpcidmapd服務開啟

service rpcidmapd start

chkconfig rpcidmapd --level 345 on

再執行掛載，應該就不會發生使用者與群組被擠壓到nobody與nogrp。
