sudo /etc/init.d/portmap restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service portmap start

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start portmap

sudo /etc/init.d/nfs-kernel-server start 的两项都OK。

showmount -e时出现：clnt_create: RPC: Program not registered。。。

此外，发现/etc 下 没有/dfs/dfstab目录。。。

求高手解答。。。

等待高人

我用sudo apt-get install nfs-kernel-server安装的，配置后重启后，没有遇到这样的问题

sudo initctl start portmap
or
sudo initctl emit start-portmap

or
apt-get install upstart

or

apt-get install

or
apt-get install nfs-kernel-server
