centos/fedora nfs的配置

参考资料：

一、准备的软件包

server ：

1. nfs
2. portmap (optional)

Client':

1. nfs
2. nfslock

二、server的配置

1.开防火墙端口

nfs是2049 setup里是NF4

portmap是111

2.配置nfs的/etc/idmapd.conf

[General]


Domain = example.com



[Mapping]


Nobody-User = nfsnobody


Nobody-Group = nfsnobody



3.启动nfs nfslock(portmap)服务

#su -c "/sbin/service portmap start"

su -c "/sbin/service nfslock start"

su -c "/sbin/service nfs start"


#su -c "/sbin/chkconfig --level 345 portmap on"

su -c "/sbin/chkconfig --level 345 nfslock on"

su -c "/sbin/chkconfig --level 345 nfs on"


4.配置nfs的分区等

su -c "mkdir -p /nfs4exports/{share1,share2,share3}"

5.修改/etc/fstab

/path/to/share1		/nfs4exports/share1	none	bind	0 0

/path/to/share2		/nfs4exports/share2	none	bind	0 0

/path/to/share3		/nfs4exports/share3	none	bind	0 0


然后mount -a

6.修改/etc/exports

这是对192.168.1.0开发 读写，如果是只读，就把rw改为ro


/nfs4exports			192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide,fsid=0)

/nfs4exports/share1		192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide)

/nfs4exports/share2             192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide)

/nfs4exports/share3             192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide)

然后 重启服务  

su -c "exportfs -rv"


7，有可能还得需要修改

/etc/hosts.allow


三、客户端的配置


1.修改 /etc/idmapd.conf

[General]

Domain = example.com


[Mapping]

Nobody-User = nfsnobody

Nobody-Group = nfsnobody


2.建立挂载目录

su -c "mkdir /mnt/shares /home/me/share1 /home/he/share2 /home/it/share3"

3.修改/etc/fstab

192.168.1.3:/usr/local/nfs	/mnt/shares	nfs4	rsize=8192,wsize=8192,timeo=14,intr

<ip-address-to-server>:/	/home/me/share1	nfs4	rsize=8192,wsize=8192,timeo=14,intr

<ip-address-to-server>:/	/home/he/share2	nfs4	rsize=8192,wsize=8192,timeo=14,intr

<ip-address-to-server>:/	/home/it/share3	nfs4	rsize=8192,wsize=8192,timeo=14,intr

然后mount -a



ps:修改完/etc/idmapd.conf, 之后需要运行service rpcidmapd restart
