NFS错误Starting NFS quotas: Cannot register service: RPC: Unable to receive; errno=Connection refused

NFS报错一例

[root@bjs0- ~]# /etc/init.d/portreserve start
Starting portreserve:                                      [  OK  ]
[root@bjs0- ~]# /etc/init.d/nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS quotas: Cannot register service: RPC: Unable to receive; errno = Connection refused

RH系操作系统在6.0版本之后没有portmap服务控制rpc的启动，由于NFS和nfslock的启动需要向rpc进行注册，rpc不启动的话就会报错。

解决方法：启动rpcbind&rpcidmap rpcbind是6.0版本后默认的RPC服务，所以要先于nfs启动。如果不启动rpcidmap则会造成用户权限的映射错误，用户的权限看起来是一串数字。

[root@bjs0- ~]# /etc/init.d/rpcbind start
Starting rpcbind:                                          [  OK  ]
[root@bjs0- ~]# /etc/init.d/rpcidmapd start
Starting RPC idmapd:                                       [  OK  ]
[root@bjs0- ~]# /etc/init.d/nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS quotas:                                       [  OK  ]
Starting NFS mountd:                                       [  OK  ]
Starting NFS daemon:                                       [  OK  ]
