When installing Nexus Repository Manager you should configure it to run as a service, so it starts back up after server reboots. It is good practice to run that service or daemon as a specific user that has only the required access righs.

Create a nexus user with sufficient access rights to run the service:

adduser nexus

Download:

wget www.sonatype.org/downloads/nexus-latest-bundle.tar.gz
tar -zxvf nexus-latest-bundle.tar.gz
ln -s nexus-x.x.x-xx nexus

Copy $NEXUS_HOME/bin/nexus to /etc/init.d/nexus and make it executable:

cp /home/nexus/nexus/bin/nexus /etc/init.d/nexus
chmod 755 /etc/init.d/nexus

Edit the script (nano /etc/init.d/nexus) and change the following variables:

NEXUS_HOME="/home/nexus/nexus"
RUN_AS_USER=nexus
PIDDIR="/home/nexus"

Set up the repository manager as a service:

cd /etc/init.d
update-rc.d nexus defaults
service nexus start

Everything Put Together

adduser nexus

wget www.sonatype.org/downloads/nexus-latest-bundle.tar.gz
tar -zxvf nexus-latest-bundle.tar.gz
ln -s nexus-x.x.x-xx nexus

cp /home/nexus/nexus/bin/nexus /etc/init.d/nexus
chmod 755 /etc/init.d/nexus

nano /etc/init.d/nexus
> NEXUS_HOME="/home/nexus/nexus"
> RUN_AS_USER=nexus
> PIDDIR="/home/nexus"

cd /etc/init.d
update-rc.d nexus defaults
service nexus start
