试验系统 centos6.5 centos6.x应该都可以用此
nfs-server的ip 192.168.1.105
nfs-client的ip 192.168.1.106
查看mount的具体挂载参数 cat /proc/mounts
[root@nfs-server ~]# yum -y install nfs-utils rpcbind
[root@nfs-server ~]#vim /etc/exports
[root@nfs-server ~]# cat /etc/exports
/aaa 192.168.1.0/24(insecure,rw,sync) 第一个/aaa是共享服务端目录 第二个是允许那些机器可以共享这个目录（这里面是权限跟参数）
/root/hhss 192.168.1.0/24(insecure,rw,sync)
/home/lzgonline/rootfs *(insecure,rw,sync,no_root_squash)
/home/lzgonline/raa 192.168.1.106/24(insecure,rw,sync,no_root_squash)
[root@nfs-server ~]#mkdir /aaa
[root@nfs-server ~]#mkdir /root/hhss
[root@nfs-server ~]#mkdir /home/lzgonline/rootfs
[root@nfs-server ~]#mkdir /home/lzgonline/raa
客户端挂在的时候报错的原因 mount.nfs: access denied by server while mounting
[root@nfs-server ~]# cat /var/log/messages | grep mount

如果要是包上面的那个错误，先查看/var/log/messge日志，出现以下信息，那就可能是在服务端没有添加insecure这个参数
1 iptables（查看两边的iptables） 2 selinux（查看两边的iptables） 3 （也是最后可能的出现的一个） /etc/exports文件没有加insecure这个参数
[root@nfs-server ~]#/etc/init.d/rpcbind restart

客户端挂载 经过检验rpcbind服务在客户端不用开启也照样能挂载 不能解开的疑惑。
[root@nfs-client ~]# yum -y install nfs-utils rpcbind
[root@nfs-client ~]# /etc/init.d/rpcbind restart
[root@nfs-client ~]# /rpcinfo -p 192.168.1.105 服务端ip 检查rpc协议通道
