解决NFS：clnt_create: RPC: Port mapper failure - Unab

解决NFS：clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)

centos7系统：

systemctl stop firewalld

vi /etc/selinux/config

setenforce 0

当在客户端查看时，出现以下错误提示时：

[root@localhost ~]# showmount -e 10.10.209.148
clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)

解决方法：

被访问的NFS服务器上的防火墙没有添加规则，向iptables里面添加如下查看的全部端口便可（目前解决的方法，固然你也能够关闭防火墙，不过这样是比较不安全的，若是你的nfs做用不大，建议你另选别的应用来替代吧！毕竟开那么多的端口，比较不安全呀！）

#vim /etc/sysconfig/iptables

#service iptables stop　　//关闭防火墙

经过#rpcinfo -p 10.10.209.148

[root@rh01 /]# rpcinfo -p 10.10.209.148program vers proto port service100000 4 tcp 111 portmapper100000 3 tcp 111 portmapper100000 2 tcp 111 portmapper100000 4 udp 111 portmapper100000 3 udp 111 portmapper100000 2 udp 111 portmapper100024 1 udp 52943 status100024 1 tcp 37706 status100011 1 udp 875 rquotad100011 2 udp 875 rquotad100011 1 tcp 875 rquotad100011 2 tcp 875 rquotad100003 2 tcp 2049 nfs100003 3 tcp 2049 nfs100003 4 tcp 2049 nfs100227 2 tcp 2049 nfs_acl100227 3 tcp 2049 nfs_acl100003 2 udp 2049 nfs100003 3 udp 2049 nfs100003 4 udp 2049 nfs100227 2 udp 2049 nfs_acl100227 3 udp 2049 nfs_acl100021 1 udp 37438 nlockmgr100021 3 udp 37438 nlockmgr100021 4 udp 37438 nlockmgr100021 1 tcp 46331 nlockmgr100021 3 tcp 46331 nlockmgr100021 4 tcp 46331 nlockmgr100005 1 udp 57177 mountd100005 1 tcp 43147 mountd100005 2 udp 49154 mountd100005 2 tcp 54810 mountd100005 3 udp 55707 mountd100005 3 tcp 58309 mountd[root@rh01 /]#
