# How to Mount a S3 Bucket on Linux Instance?

#### **Step 1:** Update the system. <a href="#step-1-update-the-system" id="step-1-update-the-system"></a>

If you are using a new Centos or Ubuntu instance, then update the system using the below commands:

a. For CentOS or Red Hat.

```
yum update all
```

b. For Ubuntu.

```
apt-get update
```

#### **Step 2:** Install the dependencies. <a href="#step-2-install-the-dependencies" id="step-2-install-the-dependencies"></a>

a. In CentOS or Red Hat.

```
sudo yum install automake fuse fuse-devel gcc-c++ git libcurl-devel libxml2-devel make openssl-devel
```

b. In Ubuntu or Debian.

```
sudo apt-get install automake autotools-dev fuse g++ git libcurl4-gnutls-dev libfuse-dev libssl-dev libxml2-dev make pkg-config
```

#### **Step 3:** Clone s3fs source code from git. <a href="#step-3-clone-s3fs-source-code-from-git" id="step-3-clone-s3fs-source-code-from-git"></a>

```
git clone https://github.com/s3fs-fuse/s3fs-fuse.git
```

#### **Step 4:** Install the code. <a href="#step-4-install-the-code" id="step-4-install-the-code"></a>

Now change to source code directory, compile and install the code with the following commands:

```
cd s3fs-fuse 
./autogen.sh
./configure --prefix=/usr --with-openssl
make
sudo make install
```

#### **Step 5:** Check the s3fs command and installation. <a href="#step-5-check-the-s3fs-command-and-installation" id="step-5-check-the-s3fs-command-and-installation"></a>

Use the below command to check where the s3fs command is placed in OS. It will also tell you the installation is ok.

```
which s3fs
```

#### **Step 6:** Paste the access key and secret key. <a href="#step-6-paste-the-access-key-and-secret-key" id="step-6-paste-the-access-key-and-secret-key"></a>

Create a new file in **/etc** with the name **passwd-s3fs** and paste the access key and secret key in the below format.

<pre><code><strong>touch /etc/passwd-s3fs 
</strong>vim /etc/passwd-s3fs
</code></pre>

```
Your_accesskey:Your_secretkey
```

#### **Step 7:** Change the permission of the file. <a href="#step-7-change-the-permission-of-the-file" id="step-7-change-the-permission-of-the-file"></a>

```
sudo chmod 640 /etc/passwd-s3fs
```

#### **Step 8:** Mount S3 bucket. <a href="#step-8-mount-s3-bucket" id="step-8-mount-s3-bucket"></a>

Now create a directory or provide the path of an existing directory and mount S3 bucket in it.

```
mkdir /mys3buckets3fs your_bucketname -o use_cache=/tmp -o allow_other -o uid=1001 -o mp_umask=002 -o multireq_max=5 /mys3bucket url=https://api-ap-south-mum-1.openstack.acecloudhosting.com:8080
```

You can make an entry in **/etc/rc.local** to automatically remount after reboot.  Find the s3fs binary file by the **which** command and make the entry before the **exit 0** line as below:

```
which s3fs 
/usr/local/bin/s3fs
```

```
nano /etc/rc.local 
/usr/local/bin/s3fs your_bucketname -o use_cache=/tmp -o allow_other -o uid=1001 -o mp_umask=002 -o multireq_max=5 /mys3bucket
```

#### **Step 9:** Check mounted s3 bucket. <a href="#step-9-check-mounted-s3-bucket" id="step-9-check-mounted-s3-bucket"></a>

```
df -Th
```

or

```
df -Th /mys3bucket
```
