使用exportfs命令来重新加载/etc/exports文件

当修改/etc/exports文件后，文件是不会立即生效的。

需要使用如下命令来重新加载exports文件：

[root@localhost huage]# exportfs -a

[root@localhost huage]# vi /etc/exports

[root@localhost huage]# showmount -e

Export list for localhost.localdomain:

/home/huage *

[root@localhost huage]# exportfs -a

[root@localhost huage]# showmount -e

Export list for localhost.localdomain:

/opt        *

/home/huage *

[root@localhost huage]# man exportfs

[root@localhost huage]# cat /var/lib/nfs/etab

/opt *(ro,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)

/home/huage *(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)
