Complete NFS configuration in a simple way

In Linux, you must pay special attention to some settings. Here we will explain the problem of NFS configuration. NFS configuration is a simple way to implement communication and access between two machines. In the embedded Linux experiment, we Configure NFS to implement access between the PC and the ARM-Linux platform in the experiment box.

The principle is to enable the LFS service in PC Linux and set a shared directory (here/arm2410). All source code editing changes can be easily modified in PC, in the ARM-Linux experimental environment, remotely mount the/arm2410 directory of PC-Linux to the local machine to implement synchronous read/write access between the two machines, in this way, the program can conveniently run the test in ARM-Linux. simply put, the purpose is to set up a shared directory, edit it in PC-Linux, and run debugging in ARM-Linux.

NFS configuration process: (NFS is installed by default, and the IP address of PC-Linux is 192.168.136.6)

1. # After ntsysv is run, select the nfs option to cancel the [] iptables Option

2. Run the security level and firewall to set the security level. Firewall: Disable

3. Run server settings-NFS to add NFS.

Directory:/arm2410;

HOST: 192.168.136 .*;

Basic permissions: read/write; ----- rw

General options: default (select Sync write request); ------- sync

User Access: the remote root directory user is selected as the local root directory user; -------- no_root_squash

Manual modification:

# Cat>/etc/exports <"EOF"

>/Arm2410 192.168.136. * (rw, sync, no_root_squash)

4. Simple testing of NFS configuration

Mount/arm2410 of PC-Linux to the/mnt directory through remote access, and check whether the/arm2410 content is in the/mnt directory. If yes, the configuration is successful.

# Mount 192.168.136.6:/arm2410/mnt

# Ls/mnt

Note: You can also choose not to set the firewall level. In this article, it is set to reduce firewall blocking and mount failure occurs.
