linux guide

By default the RedHat linux has built in Kernel support for NFS.
The Filesystem to share are defined in /etc/exports file.
In our lab session, we will configure our web server so that users can access their respective home directory and will have read- only access to /all directory. We must remind whatever share permission we specify in the /etc/exports file, the most restrictive settings will activated. The IP address of our NFS server is 192.168.100.2.
First of all, edit the /etc/exports file by inserting the following lines
/all *(ro)
/home *(rw)
Export the share using the following command –
exportfs –a –v
Restart the service –
service nfs restart
service nfslock restart

Check which folders are NFS shared –
exportfs
Go to any client computer, make a directory using mkdir command say /all
mkdir /all
Assign necessary permission, here we will set – chmod 705 –R /all
Mount the NFS shared directory to your client’s computer
mount 192.168.100.2:/all /all
At this point, users from your client computer will access /all directory in your NFS server.
Yes, it is read-only access.
Now, you have to configure your network such a way, so that, whenever a user logs in to any computer, he will get the same file system and hierarchy in his/her home directory.
In fact, whenever a user saves files to his/her home directory, it will be saved to NFS Server.
