Steps to be done for mounting s3 bucket on an amazon ec2 instance

s3_bucket_mount.sh

# download the proper versions of s3fs and fuse
wget http://s3fs.googlecode.com/files/s3fs-1.61.tar.gz
wget http://downloads.sourceforge.net/project/fuse/fuse-2.X/2.8.4/fuse-2.8.4.tar.gz

# unpack them
tar -xzf s3fs-1.61.tar.gz
tar -xzf fuse-2.8.4.tar.gz

# install dependencies
yum install gcc libstdc++-devel gcc-c++ curl-devel libxml2-devel openssl-devel mailcap glibc-devel.i386

# s3fs require fuse so install it first
cd fuse-2.8.4
./configure --prefix=/usr
make
make install

# now install s3fs
cd ../s3fs-1.61
./configure --prefix=/usr
make
make install

# make credentials file and give it proper permissions
vi /etc/passwd-s3fs
#enter the credentials in this file format is access_id:secret_key
chmod 600 /etc/passwd-s3fs

# All done ready to mount
mkdir /s3-bucketname

s3fs -o default_acl=public-read <bucket> <mountpoint>

# if you get error saying cannot load shared library libfuse.so.2:
export PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/lib64/pkgconfig/
# and now run the previous command again. Yay! the bucket is mounted!

# verify bucket is mounted properly using `df -h`
