CentOS NFS How-to Guide: Exporting and Mounting a NFS Drive
0 Comments | Posted by Qug in Networking, linux
This guide shows you how to start an NFS service on one (host) machine, export the NFS drive, and then connect to that NFS drive from a client machine.
## On the NFS host machine:
#Start Portmap service if needed.
#NFS uses portmap and a bunch of ports (that you can set in /etc/sysconfig/nfs) if you want.
See this link for more details on NFS ports.
#Start portmap service
service portmap status
service portmap start (if needed)
#Start NFS
service nfs start
#Edit /etc/exports
#Reference: https://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/ref-guide/s1-nfs-server-export.html
Format is (select the options you want):
[Directory to export] [Hosts to allow](options)
/home/just_testing 192.168.0.0/24(rw,async,wdelay,root_squash)
#Run exportfs to refresh NFS exports
exportfs -av
Be sure the proper ports are open on iptables
Reference: http://pario.no/2008/01/15/allow-nfs-through-iptables-on-a-redhat-system/
## Now on your NFS client machine:
Start portmap
service portmap start
Create a mount point and mount the NFS drive. Remember to use your own server’s IP address:
mkdir /mnt/nfs-usbdisk
mount 192.168.0.2:/home/just_testing /mnt/nfs-usbdisk
Voila ! Tail your logs if you have any problems !

How to mount an Amazon S3 bucket as virtual drive on CentOS 5.2

#Note: If you are using CentOS 4, it’s the same general process. You might have more difficulty finding the packages to install fuse and dependencies.
This is a simple guide on how to mount your S3 bucket as a “virtual drive”. This is great for backing up your data to S3, or downloading a bunch of files from S3.
#First, make sure you have the fuse package installed.
#On CentOS, fuse is available from RPMforge
#http://wiki.centos.org/AdditionalResources/Repositories/RPMForge
#Now install fuse
yum install fuse
modprobe fuse
#Download s3fs and make
cd /usr/local/src
wget http://s3fs.googlecode.com/files/s3fs-r191-source.tar.gz
cd s3fs
make
#Copy the binary to /usr/local/bin (or wherever you prefer)
cp s3fs /usr/local/bin
#Make a mount point
mkdir /mnt/s3drive
#Mount your bucket like this:
s3fs bucketname -o accessKeyId=XXXXXXXXXXXXXXXXXXXX -o secretAccessKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX /mnt/s3drive
That’s it ! You can change directory to your virtual drive or start copying files !
Go ahead and use a visual client such as CyberDuck or S3Hub to verify with your own eyes that this actually worked. ![]()
Good luck!
