Steps for installing Nexus repository manager in RedHat machine

1.  Downloading  Nexus

 Nexus Open Source distribution was used for this installation test, while a Nexus Professional is also available.To download the latest Nexus Open Source  distribution, go to http://www.sonatype.org/nexus/go and choose Nexus (TGZ) or Nexus (ZIP) ./downloads/<Nexusvesion>

2.  Installing Nexus

Copy the file to a directory other than your local (e.g., /usr/local) and  unzip the ZIP file:

$ sudo cp nexus-2.11.2-06-bundle.tar.gz /usr/local

$ unzip nexus-2.11.2-06-bundle.zip

Is recommendable to create a symbolic link  (usr/local/nexus) to the specific  nexus version directory. It makes simple to upgrade to a newer version when available

$ sudo ln -s nexus-2.11.2-06 nexus

Although it isn’t required, you may want to set an environment variable NEXUS_HOME in your environment that points to the installation directory of Nexus

NEXUS_HOME="/usr/local/nexus"

3.  Running Nexus

 To Start Nexus in a Linux machine use:

cd /usr/local/nexus
./bin/nexus console
 

 When executed you should see a feedback message and then you can follow the startup process viewing the log file changes.
