Azure VM Ubuntu 18.04

Brief setup notes for Azure VM Ubuntu 18.04 on Mac OSx.

1. Create Public and Private Keys

Create a private key. A public key will be created automatically for you.

ssh-keygen -t rsa

Make note of your private key password - this is used to authenticate below.

After creating your Azure Ubuntu 18.04 VM. Take note of your Public IP.

Ensure that the default SSH port is left open.

2. Connect from Local Machine

sudo ssh -i path/private_key user@public_ip

Use your private key password after connecting.

Ubuntu 18.04 VM

Slightly different setup than Ubuntu 14.04.

sudo apt-get update
sudo apt-get upgrade

Git

sudo apt-get update
sudo apt install git

Node

sudo apt install nodejs
sudo apt install npm

Java

Note: It's recommended to download Java 11+ directly from Oracle.

It's further recommended to use the OpenJDK 11.0.2 (and avoid other options).

See: https://jdk.java.net/archive/

sudo apt-get update
wget "https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz"
sudo tar -xzvf openjdk-11.0.2_linux-x64_bin.tar.gz
sudo mv jdk-11.0.2 /usr/lib/jvm/

# Config
sudo nano /etc/environment

# Add the line below
# JAVA_HOME="/usr/lib/jvm/jdk-11.0.2/"

# Config
sudo nano ~/.bashrc
# Add the lines below
# JAVA_HOME=/usr/lib/jvm/jdk-11.0.2/
# PATH=$JAVA_HOME/bin:$PATH
source ~/.bashrc

# Verify
echo $JAVA_HOME
javac --version

Tomcat:

groupadd tomcat
useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat
cd /opt/ 
sudo wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.2/bin/apache-tomcat-9.0.2.tar.gz
tar -xzvf apache-tomcat-9.0.2.tar.gz
sudo mv apache-tomcat-9.0.2 tomcat

Then:

# Permissions
sudo chown -hR tomcat:tomcat tomcat
sudo chmod +xr tomcat/bin/

# Config
sudo nano ~/.bashrc

# Add the line below
# CATALINA_HOME=/opt/tomcat

# Config
source ~/.bashrc

# Verify
echo $CATALINA_HOME

You can now access /opt/tomcat/bin/ to execute: sudo bash startup.sh.

Your Tomcat server will be available by default on http://YOUR_IP:8080 (note the lack of https here).
