NFS configuration in Ubuntu: uClinux Client

Article Title: NFS configuration in Ubuntu: uClinux client. Linux is a technology channel of the IT lab in China. When you perform the following operations for basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, check whether the nfs-kernel-server suite is installed.
　
Go to the new software management package.
　
Create a/nfs folder and change its permission to 777.
　
1. Modify/etc/exports as follows:
　
#/Etc/exports: the access control list for filesystems which may be exported
　
# To NFS clients. See exports (5 ).
　
#
　
# Example for NFSv2 and NFSv3:
　
#/Srv/homes hostname1 (rw, sync) hostname2 (ro, sync)
　
#
　
# Example for NFSv4:
　
#/Srv/nfs4 gss/krb5i (rw, sync, fsid = 0, crossmnt)
　
#/Srv/nfs4/homes gss/krb5i (rw, sync)
　
# Format:
　
# Host name 1 or IP1 in the directory to be shared (parameter 1, parameter 2) host name 2 or IP2 (parameter 3, parameter 4)
　
# Nfs is the shared file, and 192.168.1.242 and 192.168.1.241 are the Client IP addresses that can be shared.
　
# (Rw) the access attribute of the client to the shared file is enclosed in brackets.
　
# Note that the IP address should be a specific IP address, but it is best not to appear *
　
/Nfs 192.168.1.242 (rw)
　
/Nfs 192.168.1.241 (rw, sync)
　
2. Modify/etc/hosts as follows:
　
127.0.0.1 localhost
　
127.0.1.1 prisonmap-desktop
　
# IP address client host name
　
192.168.1.242 wengheiwei-desktop
　
192.168.1.241 uClinux
　
# The following lines are desirable for IPv6 capable hosts
　
: 1 ip6-localhost ip6-loopback
　
Fe00: 0 ip6-localnet
　
Ip6-mcastprefix ff00: 0
　
Ff02: 1 ip6-allnodes
　
Ff02: 2 ip6-allrouters
　
Ff02: 3 ip6-allhosts
　
After modifying and saving the preceding two files
　
3. Restart the portmap service and nfs-kernel-server service.
　
Command:
　
/Etc/init. d/portmap start
　
/Etc/init. d/nfs-kernel-server restart
　
4. Network IP settings of client uClinux (MAGICarm2200:
　
Ip addr: 192.168.1.241
　
Net mask: 255.255.255.0
　
BROADCAST: 192.168.1.1
　
5. Start the uclinux client and switch to the/usr directory.
　
Run mount-t nfs 192.168.1.242:/nfs/mnt-o nolock.
　
If the mounting is successful, the current path is returned.
　
If you switch to/mnt, you can see what is under the/nfs directory on the host!
