CentOS NFS How-to Guide: Exporting and Mounting a NFS Drive

with one comment

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

Format is (select the options you want):
[Directory to export] [Hosts to allow](options)


#Run exportfs to refresh NFS exports

exportfs -av

Be sure the proper ports are open on iptables

## 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 /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

with 12 comments

#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


#Now install fuse

yum install fuse
modprobe fuse

#Download s3fs and make

cd /usr/local/src
cd s3fs

#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:


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!
