1.1 启动时出现的错误
[root@znix ~]#/etc/init.d/nfs start Shutting down NFS daemon: [ OK ] Shutting down NFS mountd: [ OK ] Shutting down NFS services: [ OK ] Shutting down RPC idmapd: [ OK ] Starting NFS services: [ OK ] Starting NFS mountd: rpc.mountd: svc_tli_create: could not open connection for udp6 rpc.mountd: svc_tli_create: could not open connection for tcp6 rpc.mountd: svc_tli_create: could not open connection for udp6 rpc.mountd: svc_tli_create: could not open connection for tcp6 rpc.mountd: svc_tli_create: could not open connection for udp6 rpc.mountd: svc_tli_create: could not open connection for tcp6 [ OK ] Starting NFS daemon: rpc.nfsd: address family inet6 not supported by protocol TCP [ OK ] Starting RPC idmapd: [ OK ]
根据启动提示可以获知，inet6地址族不被支持，原因是当前主机没有加载ipv6的模块，可以重新加载一遍ipv6模块解决这个问题。
由于我的系统不需要ipv6的支持，所以还可以通过下面的操作，取消NFS的ipv6调用。
1.2 【解决办法】编辑netconfig配置文件，注释相关TCP/UDP6的信息条目
[root@znix ~]#vim /etc/netconfig # # Entries consist of: # # <network_id> <semantics> <flags> <protofamily> <protoname> # <device> <nametoaddr_libs> # # The <device> and <nametoaddr_libs> fields are always empty in this # implementation. # udp tpi_clts v inet udp - - tcp tpi_cots_ord v inet tcp - - #udp6 tpi_clts v inet6 udp - - #tcp6 tpi_cots_ord v inet6 tcp - - rawip tpi_raw - inet - - - "/etc/netconfig" 19L, 769C written
1.3 重启服务验证
