Starting NFS mountd: rpc.mountd: svc_tli_create: could not open connection for udp6

在安装好nfs后，重启服务：

service nfs restart1

得到下面报错：

Starting kernel based NFS server: idmapd mountdrpc.mountd: svc_tli_create:

rpc.mountd: svc_tli_create: could not open connection for tcp6

udp6是用于IPV6的，所以这里可以在/etc/netconfig中IPV6的注释掉：

udp        tpi_clts      v     inet     udp     -       -
tcp        tpi_cots_ord  v     inet     tcp     -       -
