Simple Note

Go to Dockerfile folder,

Add the docker-compose.yml below into it
https://github.com/benbai123/JSP_Servlet_Practice/blob/master/Practice/JAVA/JMS/RocketMQ/RocketMQCluster/docker-compose.yml

then run docker-compose up

Docker Compose will build image and run container with specified config value

Shortly,

Dockerfile define "how to create the container"

docker-compose.yml describe "how to config/run containers"

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# Apply executable permissions to the binary:

Install Docker on Ubuntu 18.04

Motivation

I want to try RocketMQ Cluster with Multi-NameServers/Brokers, but it seems change port of NameServer is not supported...

So want to run 2 NameServers in 2 Docker Containers and bind to different ports for testing.

Simple Note

Install Docker on Ubuntu 18.04 running in VirtualBox

# Uninstall old versions
sudo apt-get remove docker docker-engine docker.io containerd runc

# SET UP THE REPOSITORY
## Update the apt package index
sudo apt-get update

## Install packages to allow apt to use a repository over HTTPS
sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

## Add Docker’s official GPG key
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

## Verify that you now have the key with the fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.
sudo apt-key fingerprint 0EBFCD88

## Use the following command to set up the stable repository
sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"


# INSTALL DOCKER ENGINE - COMMUNITY
## Update the apt package index.
sudo apt-get update

## Install the latest version of Docker Engine - Community and containerd, or go to the next step to install a specific version:
sudo apt-get install docker-ce docker-ce-cli containerd.io

## Verify that Docker Engine - Community is installed correctly by running the hello-world image.
sudo docker run hello-world

RocketMQ not support modify nameServer port

Install Spark 1.6.0 on Ubuntu 14.04

Environment:

Ubuntu 14.04 installed in VirtualBox

Steps:

1. Install JDK 8

###
# install oracle jdk 8
###
sudo apt-get -y install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get -y update
sudo apt-get -y install oracle-java8-installer

# find out the path of your Java installation:
sudo update-alternatives --config java

# for me it returns
# There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-8-oracle/jre/bin/java

# edit /etc/environment
sudo gedit /etc/environment

# add this line into it, save and close
# JAVA_HOME="/usr/lib/jvm/java-8-oracle/jre/bin/java"
#
# then reload /etc/environment
source /etc/environment

2. Install scala 2.10

download scala 2.10.6 from http://www.scala-lang.org/download/2.10.6.html

extract it somewhere (I extract it to ~/Things/scala/scala-2.10.6)

again edit /etc/environment

add SCALA_HOME and PATH

after this the /etc/environment as below

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/benbai/Things/scala/scala-2.10.6/bin"
JAVA_HOME="/usr/lib/jvm/java-8-oracle/jre/bin/java"
SCALA_HOME="/home/benbai/Things/scala/scala-2.10.6"

reload /etc/environment and check scala

source /etc/environment
scala -version
# for me it returns
# Scala code runner version 2.10.6 -- Copyright 2002-2013, LAMP/EPFL

3. Get Spark 1.6.0

download spark from http://spark.apache.org/downloads.html

I choose 1.6.0 pre-build for hadoop 2.6 and later

extract it somewhere (I extract it to ~/Things/spark/spark-1.6.0-bin-hadoop2.6)

go to spark directory and test it

cd ~/Things/spark/spark-1.6.0-bin-hadoop2.6
./bin/spark-shell
# then test some command
