How To Install Kubernetes v1.14 on Ubuntu 18.04 LTS

Install Kubernetes on Ubuntu 18

Kubernetes is a free and open-source container management system that provides a platform for deployment automation, scaling, and operations of application containers across clusters of host computers. With Kubernetes, you can freely make use of the hybrid,on-premise, and public cloud infrastructure in order to run deployment tasks of your organization.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Kubernetes on a Ubuntu 18.04 (Bionic Beaver) server.

Install Kubernetes on Ubuntu 18.04 LTS

Step 1. First, make sure that all your system packages are up-to-date

sudo apt update
sudo apt upgrade

Step 2. Installing Docker.

Now we have to install Docker because Docker images will be used for managing the containers in the cluster. Run the following commands:

sudo apt install docker.io

Once the Docker is installed ensure that it is enabled to start after reboot:

sudo systemctl enable docker 
sudo systemctl start docker

Step 3. Installing Kubernetes on Ubuntu.

First, add the Kubernetes signing key on both the nodes:

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add

Next, add Xenial Kubernetes Repository on both the nodes:

sudo apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main"

Step 4. Installing Kubeadm.

The final step in the installation process is to install Kubeadm on both the nodes through the following command:

sudo apt install kubeadm

Check the version number of Kubeadm and also verify the installation through the following command:

kubeadm version

Step 4. Kubernetes Deployment.

First, disable swap memory (if running) on both the nodes:

sudo swapoff -a

Next, give hostnames to each node:

sudo hostnamectl set-hostname master-node
sudo hostnamectl set-hostname slave-node

Initialize Kubernetes on the master node:

sudo kubeadm init --pod-network-cidr=10.244.0.0/16
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

You can check the status of the master node by running the following command:

kubectl get nodes

Deploy a Pod Network through the master node:

A pod network is a medium of communication between the nodes of a network:

sudo kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Use the following command in order to view the status of the network:

kubectl get pods --all-namespaces

Now when you see the status of the nodes, you will see that the master-node is ready:

sudo kubectl get nodes

Next, add the slave node to the network in order to form a cluster:

sudo kubeadm join 192.168.100.6:6443 --token 06tl4c.oqn35jzecidg0r0m --discovery-token-ca-cert-hash sha256:c40f5fa0aba6ba311efcdb0e8cb637ae0eb8ce27b7a03d47be6d966142f2204c

Now when you run the following command on the master node, it will confirm that two nodes, the master node, and the server nodes are running on your system:

sudo kubectl get nodes

Congratulation’s! You have successfully installed Kubernetes. Thanks for using this tutorial for installing Kubernetes on Ubuntu 18.04 systems. For additional help or useful information, we recommend you to check the official Kubernetes website.

How To Install OpenCart v3.0.3.2 on Ubuntu 18.04 LTS

Install OpenCart on Ubuntu 18

OpenCart is a free open source ecommerce platform for online merchants. OpenCart provides a professional and reliable foundation from which to build a successful online store. In this tutorial we will learn you how to install OpenCart on Ubuntu 18.04 LTS.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation OpenCart on a Ubuntu 18.04 (Bionic Beaver) server.

Install OpenCart on Ubuntu 18.04 LTS

Step 1. First make sure that all your system packages are up-to-date

sudo apt update
sudo apt upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB and PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also install all required PHP modules:

apt-get install php7.1-cli php7.1-mbstring php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Download OpenCart

First thing to do is to go to OpenCart’s download page and download the latest stable version of OpenCart:

sudo mkdir -p /var/www/html/example.com
cd /tmp
wget https://github.com/opencart/opencart/releases/download/3.0.3.1/opencart-3.0.3.1.zip
unzip opencart-*.zip
sudo mv /tmp/upload/* /var/www/html/example.com/

Next, copy the configurations files:

sudo cp /var/www/html/example.com/{config-dist.php,config.php}
sudo cp /var/www/html/example.com/admin/{config-dist.php,config.php}

We will need to change some folders permissions:

sudo chown -R www-data: /var/www/html

Step 4. Configuring MariaDB for OpenCart.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next we will need to log in to the MariaDB console and create a database for the OpenCart. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for OpenCart installation:

MariaDB [(none)]> CREATE DATABASE opencart;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON opencart.* TO 'opencartuser'@'localhost' IDENTIFIED BY 'opencartuser_passwd';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q

Step 5. Configuring Apache web server for OpenCart.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘opencart.conf’ on your virtual server:
[/php]
touch /etc/apache2/sites-available/opencart.conf
ln -s /etc/apache2/sites-available/opencart.conf /etc/apache2/sites-enabled/opencart.conf
nano /etc/apache2/sites-available/opencart.conf
[/php]

Add the following lines:

<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot /var/www/html/example.com
ServerName your-domain.com
ServerAlias www.your-domain.com
<Directory /var/www/html/example.com/>
Options FollowSymLinks
AllowOverride All
</Directory>
ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common

Save and close the file. Restart the apache service for the changes to take effects:

sudo a2ensite magento.conf
sudo a2enmod rewrite
sudo systemctl restart apache2

Step 6. Accessing OpenCart.

OpenCart will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://your-domain.com/ or http://server-ip and complete the required the steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
