Oracle Unified Directory to go on Raspberry Pi Zero

Recently I ran out of movies on one of my longer train rides. Coincidentally, I had my Raspberry Pi Zero with me and thought, “There’s Java running on it, right?”. Doesn’t Oracle Unified Directory also require a JVM? OK, I guess Raspberry Pi or ARM wasn’t in focus when Oracle defined the certified platforms of Unified Directory. But hey, I don’t want to set up a production environment, I just need a small project for a long train ride…

The aim is to setup an Raspberry Pi in OTG Mode, install Java and Oracle Unified Directory and configure a small Directory Server, available whenever you need an OUD instance :-). First of all, yes, it works. But before we begin, a few things we need

  • Raspberry Pi Zero I do use a Zero 1.3 without WiFi.
  • USB OTG host cable Dedicated cable supporting USB On-The-Go (OTG). Regular USB cables usually do not support OTG. See Wikipedia On-The-Go (OTG).
  • Raspbian-Image I do recommend the latest Raspbian Stretch Lite. See Raspbian.
  • Oracle JDK 8 for ARM I do use Oracle JDK 8 Update 144 for ARM 32Bit VFP HardFP MOS Patch 26512975. Other Java version are available on MOS Note 1439822.1.
  • Oracle Unified Directory 12.2.1.3 Available through Oracle Technology Network, Oracle Software Delivery Cloud or as My Oracle Support patch 26270957. See also OUD 12.2.1.3 documentation or MOS Note 2300623.1.
  • Temorary System to install OUD Although unified directory does work on ARM, the OUI installer does not. Due to this OUD first have to be “installed” on a supported system. But later more.
  • Environment Scripts for OUD This is optional but quite handy when working on OUD environments. See blog post Environment Scripts for OUD.

In the following chapters I’ll now go through the different steps to setup the OUD “on the go” device. I work primarily on MacOS. Therefore, the individual steps are related to this operating system, but can be easily adapted to other operating systems. Depending on your individual environment, you may skip one or the other step. Shall we get started?

Setup Raspberry Pi

Install Raspian OS

After download the latest release of Raspbian Stretch Lite, we have to create the SD card to setup the OS on raspberry pi. I usually prefer to do this via commandline. Other methods are decribed on www.raspberrypi.org.

PlugIn the SD card and identify the disk via diskutil list. My SD Card is identified disk2. Your output may look different.

soe@gaia:~/ [ic12102] diskutil list
...

/dev/disk2 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *32.0 GB disk2
1: Windows_NTFS SD Card 32.0 GB disk2s1

Unmount the disk

soe@gaia:~/ [ic12102] diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful

Copy the Raspian image to the SD card.

soe@gaia:~/ sudo dd bs=1m \
if=/Data/ISO-Images/2017-09-07-raspbian-stretch-lite.img \
of=/dev/rdisk2 conv=sync

1768+1 records in
1769+0 records out
1854930944 bytes transferred in 73.667297 secs (25179843 bytes/sec)

soe@gaia:~/ [ic12102] diskutil list
...

/dev/disk2 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *32.0 GB disk2
1: Windows_FAT_32 boot 43.8 MB disk2s1
2: Linux 1.8 GB disk2s2

That’s it, the OS basically has been setup. But before we plug the SD card into the Raspberry Pi we first have to configure the OTG mode.

Configure OTG Mode

Configuring the OTG mode is straight forward, since the latest Rasbian OS does provide all. Eg. modules, kernel, etc. You just have to adjust the boot configuration.

Update cmdline.txt and add the g_ether module. You have to add modules-load=dwc2,g_ether after rootwait and before quiet. If you use vi to edit cmdline.txt your fine. But if you do use an other editor make sure you do not change the file suffix or add extra lines or line breaks to the file cmdline.txt. Everything must be on one line.
Change to the boot directory on the SD Card. Mounted as /Volumes/boot on my Mac.

soe@gaia:~/ [ic12102] cd /Volumes/boot

Update cmdline.txt

soe@gaia:/Volumes/boot/ [ic12102] vi cmdline.txt

dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=11eccc69-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait modules-load=dwc2,g_ether quiet init=/usr/lib/raspi-config/init_resize.sh

Update config.txt and add dtoverlay=dwc2 at the end of the file.

soe@gaia:/Volumes/boot/ [ic12102] vi config.txt

As last task, make sure to create an empty file named ssh in the boot folder. This tells Raspian to configure and start the ssh daemon at first system boot. Unmount the SD card and the basic OS setup is finished.

soe@gaia:/Volumes/boot/ [ic12102] touch ssh
soe@gaia:/Volumes/boot/ [ic12102] cd
soe@gaia:~/ [ic12102] diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful

Now put the SD card back in your Raspberry Pi Zero and plug in the USB cable. The first system boot will take slightly longer, since the filesystem is getting extended to the maximum size of the SD card. To be on the safe side, wait up to 5 minutes and then try to login via ssh.

soe@gaia:~/ [ic12102] ssh pi@raspberrypi.local

The Raspberry Pi Zero is now ready as headless server in OTG mode.

Setup Environment

General Configuration

This step is not really mandatory, nevertheless I do prefer to adjust a few configuration settings on my pi. First of all upgrade OS to the latest release using apt-get.

pi@raspberrypi:~ $ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

By default the Raspberry Pi hostname is set to raspberrypi. If you do have several Raspberry Pi’s it makes sense to assign names. In my case I do set the hostname to oud2go by changing /etc/hostname and /etc/hosts. In both files you have to replace raspberry with the new name.

pi@raspberrypi:~ $ sudo vi /etc/hostname
pi@raspberrypi:~ $ sudo vi /etc/hosts
pi@raspberrypi:~ $ sudo reboot

sudo: unable to resolve host raspberrypi: Connection timed out
Connection to raspberrypi.local closed by remote host.
Connection to raspberrypi.local closed.

As soon the Pi is back it’s now available by its new name.

soe@gaia:~/ [ic12102] ssh pi@oud2go.local
The authenticity of host 'oud2go.local (fe80::6554:bfdd:7283:3fa9%bridge100)' can't be established.

This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password.
pi@oud2go.local:~ $

It is a good moment to adjust the time zone from UTC to an appropriate for your Raspberry Pi’s. This can either be done using raspi-config or dpkg-reconfigure.

root@oud2go:~# dpkg-reconfigure tzdata

Current default time zone: 'Europe/Zurich'
Local time is now: Mon Oct 30 19:55:21 CET 2017.
Universal Time is now: Mon Oct 30 18:55:21 UTC 2017.

Change the softlinks for localtime will also do the job.

root@oud2go:~# ln -s -f /usr/share/zoneinfo/Europe/Zurich /etc/localtime

Oracle User

In the oracle context it is common practice to create a dedicated user and group. To keep it simple and clear I name it oracle. Indeed I did set up the environment as described in post about the OUD Base environment.

root@oud2go:~# groupadd --gid 1010 oinstall
root@oud2go:~# useradd --create-home --gid oinstall --shell /bin/bash \
--groups oinstall oracle

To install the OUD software, instance and scripts I do use a limited OFA directory structure. See also my Blog Post on OUD Base.

root@oud2go:~# mkdir -p /u00 /u01
root@oud2go:~# mkdir -p /u00/app/oracle
root@oud2go:~# mkdir -p /u00/app/oracle/etc /u00/app/oracle/local
root@oud2go:~# mkdir -p /u00/app/oracle/product /u00/app/oracle/software

root@oud2go:~# chmod a+xr /u00 /u01
root@oud2go:~# chown oracle:oinstall -R /u00 /u01

The newly created user should be allowed to use sudo similar the pi. For this a new sudoers file has to be created.

root@oud2go:~# echo "oracle ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/020_oracle-nopasswd
root@oud2go:~# chmod 440 /etc/sudoers.d/020_oracle-nopasswd

As the last custom configuration I usually distribute the ssh key’s to allow login without password authentication. You only have to include your public key in the file authorized_keys. Lets create the required .ssh user directory for root, pi and the user oracle.

root@oud2go:~# mkdir .ssh
root@oud2go:~# vi .ssh/authorized_keys
root@oud2go:~# chmod 600 .ssh/authorized_keys
root@oud2go:~# chmod 700 .ssh/
root@oud2go:~# cp -r .ssh /home/oracle
root@oud2go:~# cp -r .ssh /home/pi
root@oud2go:~# chown -R pi:pi /home/pi/.ssh
root@oud2go:~# chown -R oracle:oinstall /home/oracle/.ssh

One more thing. Until now all user still have some default password. It’s more than appropriate to change the passwords for the user root, pi and oracle.

root@oud2go:~# passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@oud2go:~# passwd pi
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@oud2go:~# passwd oracle
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

Install OUD Base

Install the OUD Base environment scripts according to blog post OUD Base. First we have to get the install scripts using curl.

oracle@oud2go:~ $ cd /u00/app/oracle
oracle@oud2go:/u00/app/oracle $ curl --cookie-jar /tmp/cookie-jar.txt \
--location-trusted "https://github.com/oehrlis/oudbase/raw/master/build/oudbase_install.sh" \

Install Oracle Software

Install Java

Since a while, Oracle does also provide Java for Raspberry Pi respectively ARM. See Oracle Java on Raspberry Pi. For OUD it’s recommend to use Oracle Java 8 rather than OpenJDK. You can download either download OracleJDK on Java SE Development Kit 8 Downloads or via My Oracle Support. I do prefer the download via My Oracle Support, since this method allows the use of wget or curl.

Create a .netrc file for curl.

oracle@oud2go:~/ [oud_pi] cd /u00/app/oracle/software

Install OUD

In principle, one should be able to install OUD directly on the Respberry Pi. OUD is unpacked and installed directly with java. But the Oracle Universal Installer or at least a small part of the installation does not work on the ARM platform. Due to this you have to install OUD on an other OS and move the installation directory onto your Raspberry Pi. In my case I do use my MacBook Pro to temporarily install OUD. Alternatively you may also copy the OUD installation from my OUD docker image. But that’s an other story. I’ll post on this topic in a couple of days.

Prepare the download installation path, variables .netca file.

soe@gaia:~/ [ic12102] export ORACLE_BASE=/u00/app/oracle
soe@gaia:~/ [ic12102] mkdir -p $ORACLE_BASE/etc $ORACLE_BASE/product

To install OUD in silent mode, we need a response file. For OUD this is a simple and straight forward text file.

soe@gaia:~/ [ic12102] echo "[ENGINE]" > $ORACLE_BASE/etc/install.rsp
soe@gaia:~/ [ic12102] echo "Response File Version=1.0.0.0.0" >> $ORACLE_BASE/etc/install.rsp
soe@gaia:~/ [ic12102] echo "[GENERIC]" >> $ORACLE_BASE/etc/install.rsp
soe@gaia:~/ [ic12102] echo "DECLINE_SECURITY_UPDATES=true" >> $ORACLE_BASE/etc/install.rsp
soe@gaia:~/ [ic12102] echo "SECURITY_UPDATES_VIA_MYORACLESUPPORT=false" >> $ORACLE_BASE/etc/install.rsp

The installer does also require a OraInventory Location file:

soe@gaia:~/ [ic12102] echo "inventory_loc=$ORACLE_BASE/oraInventory" > $ORACLE_BASE/etc/oraInst.loc
soe@gaia:~/ [ic12102] echo "inst_group=oinstall" >> $ORACLE_BASE/etc/oraInst.loc

The JAR and the response file will then be used to install OUD in silent mode

Thats it. You not have your OUD software on your pi. Now lets create an OUD instance.

Setup OUD Directory Server

Depending on your need, you may create an OUD directory server or an OUD proxy server. The setup scripts can either be execute interactive via GUI or command line or as on command. On my Raspberry Pi I do setup a directory server with just one command.

Create a password file for the OUD instance oud_pi_pwd.txt

Create the OUD directory server for Base DN dc=postgasse,dc=org with a bunch of dummy entries using oud-setup.

Oracle Unified Directory 12.2.1.3.0
Please wait while the setup program initializes...

Creating instance directory /u00/app/oracle/instances/oud_pi/OUD ..... Done.
See /u00/app/oracle/instances/oud_pi/OUD/logs/oud-setup for a detailed log of
this operation.

Configuring Directory Server ......... Done.
Importing Automatically-Generated Data (20 Entries) ....................................... Done.
Starting Directory Server ........................................ Done.

To see basic server configuration status and configuration you can launch
/u00/app/oracle/instances/oud_pi/OUD/bin/status

That’s it, we now have an empty directory server with 20 sample records 🙂 Since the Raspberry Pi only has limited resources, I’ve just configure the LDAP port. For a simple test and engineering system LDAPS is not really required. Specially because we do not setup any EUS integration.

Conclusion

It works… but the directory server is far away from a high performance setup. Nevertheless it’s a nice and handy setup for simple engineering work and simple demos. Striving for a bit more performance? You may also setup OUD in a docker container. I’ll provide more information on this topic in a couple of day’s. If you can’t wait, take a look at my Docker OUD Repository on GitHub now (docker-oud or docker-oudsm).
