Install and Configure GlusterFS(CDN) on Linux</div>
GlusterFS is a scale-out network-attached storage file system. It has found applications including cloud computing, streaming media services, and content delivery networks. GlusterFS was developed originally by Gluster, Inc. and then by Red Hat, Inc., as a result of Red Hat acquiring Gluster in 2011.

Here, we are going to configure GlusterFS volume with two replicas. Make sure you have two 64bit systems (either virtual or physical) with 1GB of memory, and one spare hard disk on each system. 
 
gluster1.hackthesec.local|192.168.12.16|Ubuntu 16.04|1GG|/dev/sdb (5GB)--Node 1 
 
gluster2.hackthesec.local|192.168.12.17|Debian 8|1GB|/dev/sdb (5GB)--Node 2 
 
client.hackthesec.local|192.168.12.8|CentOS 7 / Debian|NA|NA|Client Machine 
 
Configure DNS: 
 
GlusterFS components use DNS for name resolutions, so configure either DNS or set up a hosts entry. If you do not have a DNS on your environment, modify /etc/hosts file and update it accordingly.

sudo mkdir -p /data/gluster
sudo mount /dev/sdb1 /data/gluster
echo "/dev/sdb1 /data/gluster ext4 defaults 0 0" | sudo tee --append /etc/fstab
</pre>
Configure GlusterFS on Ubuntu 16.04: 
 
Before creating a volume, we need to create trusted storage pool by adding gluster2.hackthesec.local. You can run GlusterFS configuration commands on any one server in the cluster will execute the same command on all other servers. 
 
Here I will run all GlusterFS commands in gluster1.hackthesec.local node. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ sudo gluster peer probe gluster2.hackthesec.local
peer probe: success.

hackthesec@gluster1:~$ sudo gluster peer status

Number of Peers: 1

Hostname: gluster2.hackthesec.local
Uuid: 51470928-dfa8-42e1-a221-d7bbcb8c13bd
State: Peer in Cluster (Connected)

hackthesec@gluster1:~$ sudo gluster pool list

dc7c1639-d21c-4adf-b28f-5150229e6980 localhost Connected
</pre>
Setup GlusterFS Volume: 
 
Create a brick (directory) called "gvol0" in the mounted file system on both nodes. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">sudo mkdir -p /data/gluster/gvol0</pre>





Since we are going to use replicated volume, so create the volume named "gvol0" with two replicas.
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ sudo gluster volume create gvol0 replica 2 gluster1.hackthesec.local:/data/gluster/gvol0 gluster2.hackthesec.local:/data/gluster/gvol0
volume create: gvol0: success: please start the volume to access data</pre>

Start the volume.
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ sudo gluster volume start gvol0
volume start: gvol0: success</pre>

Check the status of the created volume. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ sudo gluster volume info gvol0

Volume Name: gvol0
Type: Replicate
Volume ID: ca102e4b-6cd1-4d9d-9c5a-03b882c76da0
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:

Brick2: gluster2.hackthesec.local:/data/gluster/gvol0
Options Reconfigured:
transport.address-family: inet
performance.readdir-ahead: on
nfs.disable: on</pre>
Setup GlusterFS Client: 
 
Install glusterfs-client package to support the mounting of GlusterFS filesystems. Run all commands as root user. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">$ su -

### CentOS / RHEL ###
yum install -y glusterfs-client

### Ubuntu / Debian ###
apt-get install -y glusterfs-client</pre>



Create a directory to mount the GlusterFS filesystem. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">mkdir -p /mnt/glusterfs</pre>

Now, mount the GlusterFS filesystem to /mnt/glusterfs using the following command.
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">mount -t glusterfs gluster1.hackthesec.local:/gvol0 /mnt/glusterfs</pre>
You can also use gluster2.hackthesec.local instead of gluster1.hackthesec.com in the above command. 
 
Verify the mounted GlusterFS filesystem. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">[root@client ~]# df -hP /mnt/glusterfs
Filesystem Size Used Avail Use% Mounted on
gluster1.hackthesec.local:/gvol0 4.8G 11M 4.6G 1% /mnt/glusterfs</pre>



You can also use below command to verify the GlusterFS filesystem.
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">[root@client ~]# cat /proc/mounts

Add below entry to /etc/fstab for automatically mounting during system boot.
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">gluster1.hackthesec.local:/gvol0 /mnt/glusterfs glusterfs defaults,_netdev 0 0</pre>
Test GlusterFS Replication and High-Availability: 
 
GlusterFS Server Side: 
 
To check the replication, mount the created GlusterFS volume on the same storage node. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ sudo mount -t glusterfs gluster1.hackthesec.local:/gvol0 /mnt
hackthesec@gluster2:~$ sudo mount -t glusterfs gluster2.hackthesec.local:/gvol0 /mnt</pre>



Data inside the /mnt directory of both nodes will always be same (replication). 
 
GlusterFS Client Side: 
Let’s create some files on the mounted filesystem on the client.hackthesec.local. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">touch /mnt/glusterfs/file1
touch /mnt/glusterfs/file2

[root@client ~]# ll /mnt/glusterfs/
total 0
-rw-r--r--. 1 root root 0 Sep 26 11:22 file1
-rw-r--r--. 1 root root 0 Sep 26 11:22 file2
</pre>


Test the both GlusterFS nodes whether they have same data inside /mnt. 
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ ll /mnt/
total 12
drwxr-xr-x 4 root root 4096 Sep 26 20:52 ./
drwxr-xr-x 24 root root 4096 Sep 25 21:57 ../
-rw-r--r-- 1 root root 0 Sep 26 20:52 file1
-rw-r--r-- 1 root root 0 Sep 26 20:52 file2

hackthesec@gluster2:~$ ls -al /mnt/
total 12
drwxr-xr-x 4 root root 4096 Sep 26 06:30 .
drwxr-xr-x 23 root root 4096 Sep 24 08:39 ..
-rw-r--r-- 1 root root 0 Sep 26 2016 file1
-rw-r--r-- 1 root root 0 Sep 26 2016 file2</pre>
As you know, we have mounted GlusterFS volume from gluster1.hackthesec.local on client.hackthesec.local, now it is the time to test the high-availability of the volume by shutting down the node. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ sudo poweroff</pre>

Now test the availability of the files, you would see files that we created recently even though the node is down.
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">[root@client ~]# ll /mnt/glusterfs/
total 0
-rw-r--r--. 1 root root 0 Sep 26 11:22 file1
-rw-r--r--. 1 root root 0 Sep 26 11:22 file2</pre>

Create some more files on the GlusterFS filesystem to check the replication. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">touch /mnt/glusterfs/file3
touch /mnt/glusterfs/file4</pre>

Verify the files count.
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">[root@client ~]# ll /mnt/glusterfs/
total 0
-rw-r--r--. 1 root root 0 Sep 26 11:22 file1
-rw-r--r--. 1 root root 0 Sep 26 11:22 file2
-rw-r--r--. 1 root root 0 Sep 26 11:26 file3
-rw-r--r--. 1 root root 0 Sep 26 11:26 file4</pre>
Since the gluster1 is down, all your data’s are now written on gluster2.hackthesec.local due to High-Availability. Now power on the node1 (gluster1.hackthesec.local). 
 
Check the /mnt of the gluster1.hackthesec.local; you should see all four files in the directory, this confirms the replication is working as expected. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none; margin-bottom: 10px; margin-top: 10px; overflow: auto; padding: 10px; width: auto; word-break: break-all;">hackthesec@gluster1:~$ sudo mount -t glusterfs gluster1.hackthesec.local:/gvol0 /mnt
[sudo] password for hackthesec:

hackthesec@gluster1:~$ ll /mnt/
total 12
drwxr-xr-x 4 root root 4096 Sep 26 20:59 ./
drwxr-xr-x 24 root root 4096 Sep 25 21:57 ../

</pre>
Install and Configure HHVM: 
 
Let’s add HHVM repository to your system. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo apt-get install -y software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0x5a16e7281be7a449 
sudo add-apt-repository "deb http://dl.hhvm.com/ubuntu $(lsb_release -sc) main"</pre>
Update the Ubuntu repositories and Install HHVM 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo apt-get update
sudo apt-get install -y hhvm
</pre>
Once the installation is complete, configure Apache web server to use HHVM. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo /usr/share/hhvm/install_fastcgi.sh</pre>
Run below command to start HHVM automatically on system boot up. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo update-rc.d hhvm defaults</pre>
Here, We’ll use HHVM as a PHP alternative. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo /usr/bin/update-alternatives --install /usr/bin/php php /usr/bin/hhvm 60</pre>
Now start HHVM service. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo systemctl start hhvm</pre>
Verify the php version. You should get the similar output like below. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">$ php -v
