How To Install VMware Workstation on Ubuntu 18.04 LTS

VMware Workstation is the most popular Virtualization software used at the desktop level on Linux like operating systems and Microsoft Windows. It allows the us to create and run multiple Virtual machines simultaneously. VMware Workstation is not an open source or free software so we need to buy its license key, though we can use its trail version for 30 days then later you can apply its license key.

How To Install Node.js on Ubuntu 18.04 LTS

Node.js is a Javascript platform for programming that enables users to build network applications very quickly. If you are using Javascript on both the front-end and the back-end, it means your development can be much more consistent and be designed within the same system.

Install Node.js on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing Node.js on Ubuntu 18.04 LTS.

Method 1. Install Node.js using Ubuntu Repository.


apt install nodejs

This will install Node.js, however we still need to install the package manager (NPM) so that 3rd party modules can be installed:

apt install npm

Verify the installation:

### nodejs --version
v8.10.0

Method 2. Install Node.js using PPA.


curl -sL https://deb.nodesource.com/setup_10.x -o nodesource_setup.sh

You can inspect the contents of this script with nano:

nano nodesource_setup.sh

Run the script:

sudo bash nodesource_setup.sh

The PPA will be added to your configuration and your local package cache will be updated automatically. After running the setup script from Nodesource, you can install the Node.js package:

apt install nodejs

In order for some npm packages to work (those that require compiling code from source, for example), you will need to install the build-essential package:

apt install build-essential

Method 3. Install Node.js using NVM (Node.js Version Manager).

Using nvm, you will be able to install multiple, self-contained versions of Node.js which will means you can control your environment much easier. It will give you on-demand access to the latest versions of Node.js, but it will also allow you to specify previous releases that your app may need. So, first we’ll want to update our local repository index and then install libssl-dev and build-essential . That can be done by running the below commands in a terminal or shell:

apt-get update
apt-get install build-essential libssl-dev

Once those are installed you need to download the setup script for NVM. Typically you can grab this from their github page. Though at the time of this writing the newest version is in the command below:

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.1/install.sh

Verify that the script is indeed the one you want and then run:

bash install.sh

To begin the install of NVM. Once it finishes you will need to reload your profile to have your changes take effect without logging back in to your server again. Run the command:

source ~/.profile

Now as we have nvm installed, we can install isolated Node.js versions. To find out the versions of Node.js that are available for installation, we need to type:

[[email protected] ~]# nvm ls-remote
. . .
v5.8.0
v5.9.0
v5.9.1
v5.10.0
v5.10.1
v5.11.0
v6.0.0

Install the version you want with the command:

nvm install [your version]

Example:

nvm install 6.0.0

Configure nvm to use the version of Node.js that you just downloaded, the command is:

nvm use 6.0.0

To verify the current version of Node.js installed, the command is:

node -v

Congratulation’s! You have successfully installed Node.js. Thanks for using this tutorial for installing Node.js on Ubuntu 18.04 LTS (Bionic Beaver) system. For additional help or useful information, we recommend you to check the official Node.js web site.

How To Install Nginx on Ubuntu 18.04 LTS

Nginx is a powerful web server software that can be used on your server. It is also known for its high performance and low memory usage which will allow fewer resources to be used but getting the job done efficiently. A popular set up is to use it as a proxy for Apache, which can then serve application requests.

Install Nginx on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing Nginx.

Installing nginx package on Ubuntu 18.04 Bionic Beaver) is as easy as running:

apt-get install nginx

After that, run the commands to enable Nginx to automatically startup when your server starts:

sudo systemctl stop nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

To test Nginx setup, open your browser and browse to the server hostname or IP address and you should see Nginx default test page as shown below:

Step 3. Configure Nginx.

Nginx site-specific configuration files are kept in /etc/nginx/conf.d/. Generally you will want a separate file in this directory for each domain or subdomain you will be hosting.

Copy the default configuration file. Replace wpcademy.com with your website’s domain name or your public IP address.


sudo cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/https://wpcademy.com.conf

Open your site’s configuration file in a nano text editor. Replace example.com in the server_name directive with your site’s domain name or IP address. If you already have content ready to serve (such as a WordPress installation) replace the path in the root directive with the path to your site’s content:


server {
 listen 80;
 server_name wpcademy.com;

#charset koi8-r;
 #access_log /var/log/nginx/host.access.log main;

location / {
 root /usr/share/nginx/html;
 index index.html index.htm;
 }

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
 #
 error_page 500 502 503 504 /50x.html;
 location = /50x.html {
 root /usr/share/nginx/html;
 }
}

Test your configuration for errors:

nginx -t

Step 4. Configure the Firewall for Nginx.
Firewall software needs to be adjusted to allow access to the service. Nginx registers itself as a service with ufw upon installation, making it straightforward to allow Nginx access:

sudo ufw allow 'Nginx HTTP'

Congratulations! You have successfully installed Nginx. Thanks for using this tutorial for installing Nginx web server in Ubuntu 18.04 LTS (Bionic Beaver) system. For additional help or useful information, we recommend you to check the official Nginx web site.
