S3FS-Fuse
S3FS is FUSE (File System in User Space) based solution to mount/unmount an Amazon S3 storage buckets and use system commands with S3 just like it was another Hard Disk.
In order to compile s3fs, You'll need the following requirements:
* Kernel-devel packages (or kernel source) installed that is the SAME version of your running kernel
* LibXML2-devel packages
* CURL-devel packages (or compile curl from sources at: curl.haxx.se/ use 7.15.X)
* GCC, GCC-C++
* pkgconfig
* FUSE (>= 2.8.4)
* FUSE Kernel module installed and running (RHEL 4.x/CentOS 4.x users - read below)
* OpenSSL-devel (0.9.8)
GnuTLS(gcrypt and nettle)
NSS
* Git
If you're using YUM or APT to install those packages, then it might require additional packaging, allow it to be installed.
Downloading & Compiling:
------------------------
In order to download s3fs, download from following url:
https://github.com/s3fs-fuse/s3fs-fuse/archive/master.zip
Or clone the following command:
git clone git://github.com/s3fs-fuse/s3fs-fuse.git
Go inside the directory that has been created (s3fs-fuse) and run: ./autogen.sh
This will generate a number of scripts in the project directory, including a configure script which you should run with: ./configure
If configure succeeded, you can now run: make. If it didn't, make sure you meet the dependencies above.
This should compile the code. If everything goes OK, you'll be greeted with "ok!" at the end and you'll have a binary file called "s3fs"
in the src/ directory.
As root (you can use su, su -, sudo) do: "make install" -this will copy the "s3fs" binary to /usr/local/bin.
Congratulations. S3fs is now compiled and installed.
Usage:
------
In order to use s3fs, make sure you have the Access Key and the Secret Key handy. (refer to the wiki)
First, create a directory where to mount the S3 bucket you want to use.
Example (as root): mkdir -p /mnt/s3
Then run: s3fs mybucket[:path] /mnt/s3
This will mount your bucket to /mnt/s3. You can do a simple "ls -l /mnt/s3" to see the content of your bucket.
If you want to allow other people access the same bucket in the same machine, you can add "-o allow_other" to read/write/delete content of the bucket.
You can add a fixed mount point in /etc/fstab, here's an example:
s3fs#mybucket /mnt/s3 fuse allow_other 0 0
This will mount upon reboot (or by launching: mount -a) your bucket on your machine.
If that does not work, probably you should specify with "_netdev" option in fstab.
All other options can be read at: https://github.com/s3fs-fuse/s3fs-fuse/wiki/Fuse-Over-Amazon
Known Issues:
-------------
s3fs should be working fine with S3 storage. However, There are couple of limitations:
* Currently s3fs could hang the CPU if you have lots of time-outs. This is *NOT* a fault of s3fs but rather libcurl. This happens when you try to copy thousands of files in 1 session, it doesn't happen when you upload hundreds of files or less.
* CentOS 4.x/RHEL 4.x users - if you use the kernel that shipped with your distribution and didn't upgrade to the latest kernel RedHat/CentOS gives, you might have a problem loading the "fuse" kernel. Please upgrade to the latest kernel (2.6.16 or above) and make sure "fuse" kernel module is compiled and loadable since FUSE requires this kernel module and s3fs requires it as well.
* Moving/renaming/erasing files takes time since the whole file needs to be accessed first. A workaround could be to use s3fs's cache support with the use_cache option.

s3fs
====
s3fs allows Linux and Mac OS X to mount an S3 bucket via FUSE.
s3fs preserves the native object format for files, allowing use of other tools like [s3cmd](http://s3tools.org/s3cmd).
Features
--------
* large subset of POSIX including reading/writing files, directories, symlinks, mode, uid/gid, and extended attributes
* compatible with Amazon S3, Google Cloud Storage, and other S3-based object stores
* large files via multi-part upload
* renames via server-side copy
* optional server-side encryption
* data integrity via MD5 hashes
* in-memory metadata caching
* local disk data caching
* user-specified regions, including Amazon GovCloud
* authenticate via v2 or v4 signatures
Installation
------------
Ensure you have all the dependencies:
On Ubuntu 14.04:
```
sudo apt-get install automake autotools-dev g++ git libcurl4-gnutls-dev libfuse-dev libssl-dev libxml2-dev make pkg-config
```
On CentOS 7:
```
sudo yum install automake fuse-devel gcc-c++ git libcurl-devel libxml2-devel make openssl-devel
```
Compile from master via the following commands:
```
git clone https://github.com/s3fs-fuse/s3fs-fuse.git
cd s3fs-fuse
./autogen.sh
./configure
make
sudo make install
```
Examples
--------
Enter your S3 identity and credential in a file `/path/to/passwd`:
```
echo MYIDENTITY:MYCREDENTIAL > /path/to/passwd
```
Make sure the file has proper permissions (if you get 'permissions' error when mounting) `/path/to/passwd`:
```
chmod 600 /path/to/passwd
```
Run s3fs with an existing bucket `mybucket` and directory `/path/to/mountpoint`:
```
s3fs mybucket /path/to/mountpoint -o passwd_file=/path/to/passwd
```
If you encounter any errors, enable debug output:
```
s3fs mybucket /path/to/mountpoint -o passwd_file=/path/to/passwd -d -d -f -o f2 -o curldbg
```
You can also mount on boot by entering the following line to `/etc/fstab`:
```
s3fs#mybucket /path/to/mountpoint fuse _netdev,allow_other 0 0
```
Limitations
-----------
Generally S3 cannot offer the same performance or semantics as a local file system. More specifically:
* random writes or appends to files require rewriting the entire file
* metadata operations such as listing directories have poor performance due to network latency
* [eventual consistency](https://en.wikipedia.org/wiki/Eventual_consistency) can temporarily yield stale data
* no atomic renames of files or directories
* no coordination between multiple clients mounting the same bucket
* no hard links
References
----------
* [s3backer](https://github.com/archiecobbs/s3backer) - mount an S3 bucket as a single file
* [s3fs-python](https://fedorahosted.org/s3fs/) - an older and less complete implementation written in Python
* [S3Proxy](https://github.com/andrewgaul/s3proxy) - combine with s3fs to mount EMC Atmos, Microsoft Azure, and OpenStack Swift buckets
* [s3ql](https://bitbucket.org/nikratio/s3ql/) - similar to s3fs but uses its own object format
* [YAS3FS](https://github.com/danilop/yas3fs) - similar to s3fs but uses SNS to allow multiple clients to mount a bucket

this option can not be specified with use_rrs. specifying only "use_sse" or "use_sse=1" enables Server-Side Encryption.(use_sse=1 for old version)
specifying this option with file path which has some SSE-C secret key enables Server-Side Encryption with Customer-Provided Encryption Keys.(use_sse=file)
the file must be 600 permission. the file can have some lines, each line is one SSE-C key. the first line in file is used as Customer-Provided Encryption Keys for uploading and change headers etc.
if there are some keys after first line, those are used downloading object which are encripted by not first key.
so that, you can keep all SSE-C keys in file, that is SSE-C key history.
if AWSSSECKEYS environment is set, you can set SSE-C key instead of this option.
Specify three type Amazon's Server-Site Encryption: SSE-S3, SSE-C or SSE-KMS. SSE-S3 uses Amazon S3-managed encryption keys, SSE-C uses customer-provided encryption keys, and SSE-KMS uses the master key which you manage in AWS KMS.
You can specify "use_sse" or "use_sse=1" enables SSE-S3 type (use_sse=1 is old type parameter).
Case of setting SSE-C, you can specify "use_sse=custom", "use_sse=custom:<custom key file path>" or "use_sse=<custom key file path>"(only <custom key file path> specified is old type parameter).
You can use "c" for short "custom".
The custom key file must be 600 permission. The file can have some lines, each line is one SSE-C key.
The first line in file is used as Customer-Provided Encryption Keys for uploading and changing headers etc.
If there are some keys after first line, those are used downloading object which are encrypted by not first key.
So that, you can keep all SSE-C keys in file, that is SSE-C key history.
If you specify "custom"("c") without file path, you need to set custom key by load_sse_c option or AWSSSECKEYS environment.(AWSSSECKEYS environment has some SSE-C keys with ":" separator.)
This option is used to decide the SSE type.
So that if you do not want to encrypt a object at uploading, but you need to decrypt encrypted object at downloaing, you can use load_sse_c option instead of this option.
For setting SSE-KMS, specify "use_sse=kmsid" or "use_sse=kmsid:<kms id>".
You can use "k" for short "kmsid".
If you san specify SSE-KMS type with your <kms id> in AWS KMS, you can set it after "kmsid:"(or "k:").
If you specify only "kmsid"("k"), you need to set AWSSSEKMSID environment which value is <kms id>.
You must be careful about that you can not use the KMS id which is not same EC2 region.

If this option is not specified, s3fs uses "us-east-1" region as the default.
If the s3fs could not connect to the region specified by this option, s3fs could not run.
But if you do not specify this option, and if you can not connect with the default region, s3fs will retry to automatically connect to the other region.
