I find that I often need to remember the steps to configuring NFSv4 on Fedora. Note that under Fedora 18, nfs-utils may already installed depending on the options you select.
[root@master ~]# yum -y install nfs-utils
[root@master ~]# vi /etc/idmapd.conf
# line 5: uncomment and change to your domain name
Domain = server.world
[root@master ~]# vi /etc/exports
# write like below *note
/home 10.0.0.0/24(rw,sync,no_root_squash,no_all_squash)# *note
/home ⇒ shared directory
10.0.0.0/24 ⇒ range of networks NFS permits accesses
rw ⇒ writable
sync ⇒ synchronize
no_root_squash ⇒ enable root privilege
no_all_squash ⇒ enable users’ authority[root@master ~]# systemctl start rpcbind.service
[root@master ~]# systemctl start nfs-server.service
[root@master ~]# systemctl start nfs-lock.service
[root@master ~]# systemctl start nfs-idmap.service
[root@master ~]# systemctl enable rpcbind.service
[root@master ~]# systemctl enable nfs-server.service
[root@master ~]# systemctl enable nfs-lock.service
[root@master ~]# systemctl enable nfs-idmap.service
