nfs 挂载不成功，求助！

zippozhangDK

小弟今天配nfs出现了一个问题，查阅各种资料，一直未能解决，希望高手相助

server端（192.168.1.201）
1./etc/exports
     /mnt/storage *.example.com(rw,sync,no_root_squash)

2.www.example.com --- 192.168.1.202 (正向解析和反向解析均无问题，在server端和client端均进行了测试)

3.192.168.1.201 为DNS服务器，NFS服务器

client端（192.168.1.202）
1. mount -t nfs 192.168.1.201:/mnt/storage /mnt

报错：mount.nfs: access denied by server while mounting 192.168.1.201:/mnt/storage、

PS：1.如果将/etc/exports的配置改为/mnt/storage  *(rw,sync,no_root_squash)挂载就很正常
      2.iptable已经清空
      3. selinux已经关

     *.example.com  可以这样写么，换成IP的正常，那肯定就是这里出现问题。

问题已找到，在/etc/exports 里写成
*.example.com (rw,sync,no_root_squash) 中间加上空格就可以了！！！  求高手解释原理~~~

    上图27行也没有加空格啊？
27 .  /tmp    192.168.0.0/24(ro)      localhost(rw,async)     *.example.com(ro,sync)

灵异事件，看不出有什么问题，vmware上测试也没有这个问题.

1. [root@co601 ~]# cat /etc/exports
   
2. /nfsshare/root *.cs.com(rw,sync,no_root_squash)
   
3. 
   
4. [root@co601 ~]# showmount -e localhost
   
5. Export list for localhost:
   
6. /nfsshare/root *.cs.com
   
7. [root@co601 ~]# getenforce
   
8. Disabled
   
9. [root@co601 ~]# service iptables status
   
10. iptables: Firewall is not running.
