Step 1 – GlusterFS Pre-Installation<\/h2>\n
The first step we need to do before installing glusterfs on all servers is configuring the hosts’ file and add GlusterFS repository to each server.<\/p>\n
Configure Hosts File<\/h3>\n
Log in to each server and get the root access with ‘sudo su’ command, then edit the ‘\/etc\/hosts’ file.<\/p>\n
vim \/etc\/hosts<\/p>\n
Paste hosts configuration below.<\/p>\n
10.0.15.10 gfs01 \n10.0.15.11 gfs02 \n10.0.15.12 client01<\/pre>\n
Save and exit.<\/p>\n
Now ping each server using the hostname as below.<\/p>\n
ping -c 3 gfs01
ping -c 3 gfs02
ping -c 3 client01<\/p>\nEach hostname will resolve to each server IP address.<\/p>\n
![\"Configure](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts.png\" "\\"\\"")
<\/a><\/p>\nAdd GlusterFS Repository<\/h3>\n
Install the software-properties-common package to the system.<\/p>\n
sudo apt install software-properties-common -y<\/p>\n
Add the glusterfs key and repository by running commands below.<\/p>\n
wget -O- https:\/\/download.gluster.org\/pub\/gluster\/glusterfs\/3.12\/rsa.pub | apt-key add –
sudo add-apt-repository ppa:gluster\/glusterfs-3.12<\/p>\nThe command will update all repositories. And we’ve already added the glusterfs repository to all systems.<\/p>\n
![\"Add](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-1.png\" "\\"\\"")
<\/a><\/p>\nStep 2 – Install GlusterFS Server<\/h2>\n
In this step, we will install the glusterfs server on ‘gfs01’ and ‘gfs02’ servers.<\/p>\n
Install glusterfs-server using the apt command.<\/p>\n
sudo apt install glusterfs-server -y<\/p>\n
Now start the glusterd service and enable it to launch everytime at system boot.<\/p>\n
sudo systemctl start glusterd
sudo systemctl enable glusterd<\/p>\nGlusterfs server is now up and running on the ‘gfs01’ and ‘gfs02’ servers.<\/p>\n
Check the services and the installed software version.<\/p>\n
systemctl status glusterd
glusterfsd –version<\/p>\n![\"Install](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-2.png\" "\\"\\"")
<\/a><\/p>\nStep 3 – Configure GlusterFS Servers<\/h2>\n
Glusterd services are now up and running, and the next step we will do is to configure those servers by creating a trusted storage pool and creating the distributed glusterfs volume.<\/p>\n
Create a Trusted Storage Pool<\/h3>\n
From the ‘gfs01’ server, we need to add the ‘gfs02’ server to the glusterfs storage pool.<\/p>\n
Run the command below.<\/p>\n
gluster peer probe gfs02<\/p>\n
Now we will see the result ‘peer probe: success’, and we’ve added the ‘gfs02’ server to the storage trusted pool.<\/p>\n
Check the storage pool status and list using commands below.<\/p>\n
gluster peer status
gluster pool list<\/p>\nAnd you will see the ‘gfs02’ server is connected to the peer cluster, and it’s on the pool list.<\/p>\n
![\"Create](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-3.png\" "\\"\\"")
<\/a><\/p>\nSetup Distributed GlusterFS Volume<\/h3>\n
After creating the trusted storage pool, we will create a new distributed glusterfs volume. We will create the new glusterfs volume based on the system directory.<\/p>\n
Note:<\/strong><\/p>\n
- \n
- For the server production, it’s recommended to create the glusterfs volume using the different partition, not using a system directory.<\/li>\n<\/ul>\n
Create a new directory ‘\/glusterfs\/distributed’ on each bot ‘gfs01’ and ‘gfs02’ servers.<\/p>\n
mkdir -p \/glusterfs\/distributed<\/p>\n
And from the ‘gfs01’ server, create the distributed glusterfs volume named ‘vol01’ with 2 replicas ‘gfs01’ and ‘gfs02’.<\/p>\n
gluster volume create vol01 replica 2 transport tcp \\
gfs01:\/glusterfs\/distributed \\
gfs02:\/glusterfs\/distributed \\
force<\/p>\nNow we’ve created the distributed volume ‘vol01’ – start the ‘vol01’ and check the volume info.<\/p>\n
gluster volume start vol01
gluster volume info vol01<\/p>\nAnd following is the result.<\/p>\n
![\"Setup](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-4.png\" "\\"\\"")
<\/a><\/p>\nAt this stage, we created the ‘vol01’ volume with the type ‘Replicate’ and 2 bricks on ‘gfs01’ and ‘gfs02’ server. All data will be distributed automatically to each replica server, and we’re ready to mount the volume.<\/p>\n
Below the ‘vol01’ volume info from the ‘gfs02’ server.<\/p>\n
![\"volume](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-5.png\" "\\"\\"")
<\/a><\/p>\nStep 4 – Setup GlusterFS Client<\/h2>\n
In this step, we will mount the glusterfs volume ‘vol01’ to the Ubuntu client, and we need to install the glusterfs-client to the client server.<\/p>\n
Install glusterfs-client to the Ubuntu system using the\u00a0apt command.<\/p>\n
sudo apt install glusterfs-client -y<\/p>\n
Now create a new directory ‘\/mnt\/glusterfs’ when the glusterfs-client installation is complete.<\/p>\n
mkdir -p \/mnt\/glusterfs<\/p>\n
And mount the distributed glusterfs volume ‘vol01’ to the ‘\/mnt\/glusterfs’ directory.<\/p>\n
sudo mount -t glusterfs gfs01:\/vol01 \/mnt\/glusterfs<\/p>\n
Now check the available volume on the system.<\/p>\n
df -h \/mnt\/glusterfs<\/p>\n
And we will get the glusterfs volume mounted to the ‘\/mnt\/glusterfs’ directory.<\/p>\n
![\"setup](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-6.png\" "\\"\\"")
<\/a><\/p>\nAdditional:<\/strong><\/p>\n
To mount glusterfs permanently to the Ubuntu client system, we can add the volume to the ‘\/etc\/fstab’.<\/p>\n
Edit the ‘\/etc\/fstab’ configuration file.<\/p>\n
vim \/etc\/fstab<\/p>\n
And paste configuration below.<\/p>\n
gfs01:\/vol01 \/mnt\/glusterfs glusterfs defaults,_netdev 0 0<\/pre>\n
Save and exit.<\/p>\n
Now reboot the server and when it’s online, we will get the glusterfs volume ‘vol01’ mounted automatically through the fstab.<\/p>\n
Step 5 – Testing Replicate\/Mirroring<\/h2>\n
In this step, we will test the data mirroring on each server nodes.<\/p>\n
Mount the glusterfs volume ‘vol01’ to each glusterfs servers.<\/p>\n
On ‘gfs01’ server.<\/p>\n
mount -t glusterfs gfs01:\/vol01 \/mnt<\/p>\n
On ‘gfs02’ server.<\/p>\n
mount -t glusterfs gfs02:\/vol01 \/mnt<\/p>\n
Now back to the Ubuntu client and go to the ‘\/mnt\/glusterfs’ directory.<\/p>\n
cd \/mnt\/glusterfs<\/p>\n
Create some files using touch command.<\/p>\n
touch file01 file02 file03<\/p>\n
![\"Test](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-7.png\" "\\"\\"")
<\/a><\/p>\nNow check on each\u00a0 – ‘gfs01’ and ‘gfs02’ – server, and we will get all the files that we’ve created from the client machine.<\/p>\n
cd \/mnt\/
ls -lah<\/p>\nHere’s the result from the ‘gfs01’ server.<\/p>\n
![\"Result](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-8.png\" "\\"\\"")
<\/a><\/p>\nAnd here’s the result from the ‘gfs02’ server.<\/p>\n
![\"Result](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/07\/high-availability-storage-with-glusterfs-on-ubuntu-18-04-lts-9.png\" "\\"\\"")
<\/a><\/p>\nAll files that we created from the client machine will be distributed to all the glusterfs volume node servers.<\/p>\n
