first-class error printing: [email protected]~:clnt_create:  RPC: Port Mapper Failure - unable  to Receive: errno 113 (NoRoute tohost)

The second type of error printing: [email protected]~:RPC: program not registered

The first type of error is caused by two reasons.

① is due to the Rpcbind service not starting properly or the service is abnormal, in CentOS 6.3, the Portmap service is responsible for Rpcbind, which we can confirm through Yum install Portmap. The source server resolves the package to rpcbind itself.

② firewall configuration issues. Add the ports that are used by NFS and RPC services, such as 111, 2049, by modifying the/etc/iptables script directory. Or shut down the firewall directly (not recommended unless your virtual machine is on a secure LAN or the virtual machine is not used as a network server). It is also possible to configure and edit firewall rules (iptables) through a graphical interface. Note here that in CentOS 6.3, there are multiple iptables script files in the/etc directory, making sure to select IPV4 Related scripts (if you use IPV6, select the corresponding script modifications).
