CentOS6.x的NFS配置跟CentOS5.x不太一样，不光是安装包及服务名变了，还总有各种古怪的事情，今天遇到了NFS客户端mount NFS之后目录的属主变成了nobody:nobody，折腾了半天，终于找到了解决办法：
本次案例：
OS： CentOS-6.5
NFS Server: 192.168.100.101 nfsserver.sudops.com
NFS Client: 192.168.100.102 nfsclient.sudops.com
服务端配置：
# cat /etc/exports
/data/storage 192.168.100.0/255.255.255.0(rw,sync,all_squash,anonuid=0,anongid=0)
# cat /etc/idmapd.conf
[General]
#Verbosity = 0
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
#Domain = local.domain.edu

# cat /etc/exports
/data/storage192.168.100.0/255.255.255.0(rw,sync,all_squash,anonuid=0,anongid=0)
# cat /etc/idmapd.conf
[General]
#Verbosity = 0
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
#Domain = local.domain.edu
改成
[General]
#Verbosity = 0
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
#Domain = local.domain.edu
Domain = sudops.com

[General]
#Verbosity = 0
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
#Domain = local.domain.edu
Domain=sudops.com
重启NFS服务端
# /etc/init.d/nfs restart
# /etc/init.d/rpcbind restart
# /etc/init.d/rpcidmapd restart
1

3
# /etc/init.d/nfs restart
# /etc/init.d/rpcbind restart
# /etc/init.d/rpcidmapd restart
客户端配置：
跟服务端一样也要修改/etc/idmapd.conf
重启客户端应用
# /etc/init.d/rpcbind restart
# /etc/init.d/rpcidmapd restart
1
2
# /etc/init.d/rpcbind restart
# /etc/init.d/rpcidmapd restart
重新mount
# umount -l /local/storage
# mount -t nfs 192.168.100.101:/data/storage/ /local/storage
1
2
# umount -l /local/storage
# mount -t nfs 192.168.100.101:/data/storage/ /local/storage
这次终于跟NFS的export目录属主保持一致啦！
