Build an NFS server in linux

Set up an NFS server in linux-a Linux Enterprise Application-a Linux server application. For more information, see. I. NFS Overview:
NFS is a Network File System and a Network protocol for File sharing between hosts.

Ii. NFS Server installation:
In RHEL4, the NFS service installs "nfs-utils" and "portmap". Generally, this software package is installed by default.

Iii. NFS Server Configuration:

1. Check whether the software packages NFS-utils and portmap are installed before configuring nfs.
# Rpm-q nfs-utils portmap
Nfs-utils-1.0.6-46
Portmap-4.0-63

2. If not, you can go to the RedHat/PMS directory on the 2nd installation discs of rhel4.
# Cd/cdrom/RedHat/PMS/
# Ls nfs-utils * portmap *
Nfs-utils-1.0.6-46.i386.rpm portmap-4.0-63.rpm
Installation: rpm-ivh nfs-utils-1.0.6-46.i386.rpm portmap-4.0-63.rpm

3. Configuration:
The configuration file of the NFS server is in the "/etc/" directory and the file name is "exports ".
# Vi/etc/exports
In the "exports" folder, each row records the setting of an NFS file sharing directory. The format is as follows:
NFS shared directory name (PATH) Client IP address (setting options)

For example:
/Home/share * (sync. ro)

4. Host address format:
Host with the specified IP address 192.168.1.10
Host with the specified domain name www.linuxdiyf.com
All hosts in the specified CIDR block of 192.168.1.0/24
* .Zmc.com all hosts in the specified domain
* All Hosts

5. Restart the NFS service after saving the "exports" file. The command is as follows:
Service nfs restart
Service portmap restart

6. Run the following command to mount an NFS shared file to a customer:
Server IP Address: Shared Folder path client path-t nfs

7. showmount command
Display the NFS server output directory list:
Showmount-e
Display the shared directory mounted to the NFS server:
Showmount-d
Display the NFS server client and mounted directory:
Showmount-

8. exportfs command
To make the content of the new "exports" file take effect, the command is as follows:
Exportfs-rv
Stop outputting all directories. The command is as follows:
Exportfs-auv
To enable all directories, run the following command:
Exportfs-rv
