[dash-dev] Installing Nexus 1.8.0.1 
Hello,

To get us started, I'm now installing Nexus 1.8.0.1. The update to 1.9
should be easy.

Here is the full installation log:


Installation protocol

-----

I created the user "nexus", group "nexus"

# groupadd nexus
# useradd -g nexus -m -c "Nexus Service" nexus

-----

I copied the SSH keys from ~admin to ~nexus

# cd ~nexus
# cp -r /home/admin/.ssh .
# chown nexus:nexus .ssh/

-----

Logging in as "nexus" works from remote. I'm using this in my ~/.ssh/config:

Host nexus
    HostName maven.eclipse.org
    User nexus
    ForwardAgent yes

-----

I created the scripts "vi" and "vim" for root. They create a backup of
any edited file in /root/vibak/

That makes it much more simple to find the answer to these two questions:

1. Who changed something in the last three days?
2. What changed?
3. If I need to set up a new server, what do I have to change

-----

As user "nexus":

I downloaded Nexus 1.8.0.1

> wget
http://nexus.sonatype.org/downloads/older/nexus-oss-webapp-1.8.0.1-bundle.tar.gz
> wget
http://nexus.sonatype.org/downloads/older/nexus-oss-webapp-1.8.0.1-bundle.tar.gz.sha1

-----

Checked the SHA1 sum:

> sha1sum nexus-oss-webapp-1.8.0.1-bundle.tar.gz

Unfortunately, the sha1-file isn't suitable as input for sha1sum. But
the numbers seem to match.

-----

Unpacking Nexus

> tar xzf nexus-oss-webapp-1.8.0.1-bundle.tar.gz

-----

Creating a symbolic link to the current version of Nexus

> ln -s nexus-oss-webapp-1.8.0.1 nexus-current

-----

Creating a symbolic link for the start script of Nexus

> ln -s $HOME/nexus-current/bin/jsw/linux-x86-64/nexus bin

Checking Java version:

> java -version
libnuma: Warning: /sys not mounted or no numa system. Assuming one node:
Datei oder Verzeichnis nicht gefunden
java version "1.6.0"
Java(TM) SE Runtime Environment (build pxa6460sr8fp1-20100624_01(SR8 FP1))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux amd64-64
jvmxa6460sr8ifx-20100609_59383 (JIT enabled, AOT enabled)
J9VM - 20100609_059383
JIT  - r9_20100401_15339ifx2
GC   - 20100308_AA)
JCL  - 20100624_01

I'm not really happy with the "libnuma" warning but I'm not trying to
fix this right now.

-----

Installing Nexus (following the instruction at
http://www.sonatype.com/books/nexus-book/reference/ch03s02.html)

Done already with the links and stuff above.

-----

Configuring Nexus

I was thinking about changing the port from 8081 to 80 but then, we'd
need to run Nexus as root. I think I'll install a web server that
redirects the requests.

-----

Starting nexus

> nexus start

Starting worked. But I couldn't connect with
http://maven.eclipse.org:8081/nexus/

The firewall doesn't let me in.
