Hello Everyone,

In this tutorial,

Let us Install and Manage Sonatype Nexus 3 on Ubuntu Desktop 15.04 – 64Bit

You can also install in Debain 8, Linux Mint 17.2

Website :- http://www.sonatype.com/

Requirment :- http://www.sonatype.com/nexus/try-compare-buy/nexus-requirements

Install Oracle JDK Java (JRE/JDK)

Download Java from Website :- http://www.oracle.com/technetwork/java/javase/downloads/index.html

Watch Video How to Install JDK Java :- https://goo.gl/CYnMQj

Type 'su' and then type "sudo apt-get update" then follow below steps :-

Step1 :- sudo apt-get install openjdk-8-jre

Step2 :- sudo apt-get install -y openjdk-8-jdk

Step3 :- java -version

Repository Management with Nexus

Downloading Nexus OSS Website :- http://www.sonatype.org/nexus/go

Step4 :- cd /usr/local

Step5 :- sudo mkdir nexus

Step6 :- sudo wget https://sonatype-download.global.ssl.fastly.net/nexus/oss/nexus-2.11.3-01-bundle.tar.gz

Step7 :- sudo tar -xvzf nexus-2.11.3-01-bundle.tar.gz

For Nexus Pro the equivalent commands would be

Step8 :- unzip nexus-professional-2.11.3-01-bundle.zip

Step9 :- tar xvzf nexus-professional-2.11.3-01-bundle.tar.gz

Note :- If you are installing Nexus on a server, you might want to use a directory other than your home directory.

On a Unix machine, this book assumes that Nexus is installed in/usr/local/nexus-2.11.3-01 with a symbolic link/usr/local/nexus to the nexus directory.

Step10 :- sudo cp nexus-2.11.3-01-bundle.tar.gz /usr/local

Step11 :- cd /usr/local

Step12 :- sudo tar xvzf nexus-2.11.3-01-bundle.tar.gz

Step13 :- sudo ln -s nexus-2.11.3-01/ nexus

Set up some variable (using the global profile).

Step14 :- sudo gedit /etc/profile

And add these lines

export NEXUS_PLATFORM=linux-x86-64

export NEXUS_HOME=/usr/local/nexus-2.11.3-01

export NEXUS_EXEC=$NEXUS_HOME/usr/local/nexus-2.11.3-01/bin/$NEXUS_PLATFORM

export PATH=$NEXUS_EXEC:$PATH

Modify the file that launches Nexus

Step15 :- sudo gedit $NEXUS_EXEC/nexus

And modify these lines

# Application

APP_NAME="nexus"

APP_LONG_NAME="Sonatype Nexus OSS“

# Location of the pid file.

PIDDIR="/var/run”

Step16 :- sudo cp $NEXUS_EXEC/nexus /etc/init.d/nexus

Step17 :- sudo chmod 755 /etc/init.d/nexus

Step18 :- sudo update-rc.d nexus defaults

Step19 :- sudo gedit /etc/init.d/nexus

Add the lines COMMAND_LINE="/usr/local/nexus-2.11.3-01/bin/jsw/linux-x86-64/nexus start"

eval $COMMAND_LINE

Step20 :- sudo chmod 755 /etc/init.d/nexus

Step21 :- sudo update-rc.d nexus defaults

Upgrading Nexus

To upgrade Nexus, unpack the Nexus archive in the directory that contains the existing Nexus installation. Once the archive is unpacked, the new Nexus application directory should be a sibling to your existing sonatype-work/ directory.

Running Nexus

When you start Nexus, you are starting a web server on the default port 0.0.0.0:8081. Nexus runs within a servlet container called Eclipse Jetty, and it is started with a native service wrapper called the Tanuki Java Service Wrapper.

To start Nexus on a Unix-like platform like Linux, Mac OS X or Solaris use

cd /usr/local/nexus-2.11.3-01/bin

./bin/nexus console

./bin/nexus start

tail -f logs/wrapper.log

To use Nexus, fire up a web browser and type in the URL

http://localhost:8081/nexus.

The default administrator username and password combination is admin and admin123.
