Installation

1. install oracle idk 8 and configure JAVA_HOME, make it as default
2. download nexus oss 3.2

sudo tar xvzf nexus-3.2.0-01-unix.tar.gz -C /opt
sudo chmod -R 777 sonatype-work

1. to start it from terminal manually, just enter nexus installation home/bin, then run command ./nexus run

In this case, we need to press ctrl+c keys to stop it.

1. access it by :

http://localhost:8081

Make it as a service

In order to make it start automatically after server reboot, we need to make it as service.

It is a good practice to run that service as a specific user that has only required access rights rather than root user.

We can configure the repository manager to run as a service with init.d or systemd. Both are startup frameworks used in Linux-based systems such as Ubuntu and CentOS.

• add linux user for nexus sudo vi /opt/nexus/bin/nexus.rc

make previous file looks like run_as_user="linux user"

• create link sudo ln -s /opt/nexus/bin/nexus /etc/init.d/nexus

• config init.d

cd /etc/init.d
sudo chkconfig --add nexus
sudo chkconfig --levels 345 nexus on
sudo service nexus start

The second command adds nexus as a service to be started and stopped with the command. chkconfig manages the symbolic links in /etc/rc[0-6].d which control the services to be started and stopped when the operating system restarts or transitions between run-levels. The third command adds nexus to run-levels 3, 4, and 5. Then the service command starts the repository manager.

Access it from other computers

sudo firewall-cmd --zone=public --permanent --add-service=http
sudo firewall-cmd --zone=public --add-port=8081/tcp --permanent
sudo firewall-cmd --reload
