Prerequisites

Ubuntu Server LTS 20.04 (minimal install, no GUI), 8GB RAM, 100GB HDD
PG 14 recommended (>12 required), JDK 1.8 ( 311+ ), OpenSSL, Resin 4.0.66

PostgreSQL

Installation Instructions: https://www.postgresql.org/download/linux/ubuntu/

Create the file repository configuration:

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

Import the repository signing key:

wget --no-check-certificate -q -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

Update the package lists:

sudo apt-get update

sudo apt-get -y install postgresql-14

Tune postgresql: https://pgconfigurator.cybertec-postgresql.com/

File to edit when tuning PG:

sudo nano /etc/postgresql/14/main/postgresql.conf

Starting (or stopping) postgres: ( stop | start | restart )

sudo pg_ctlcluster 14 main start

Set password for user "postgres"

sudo -u postgres psql postgres
\password postgres ( enter desired password when prompted )
\q (to exit the posgreSQL command interface )

Edit pg_hba.conf to force password confirmation for postgres commands
Look for --- "Database administrative login by Unix domain socket", replace "peer" with "md5"

sudo nano /etc/postgresql/14/main/pg_hba.conf

Restart PG for changes to take effect:

sudo pg_ctlcluster 14 main restart

Create empty registry database:

sudo -u postgres psql postgres
CREATE database registry;
\q

Import CoCCA database backup:

psql -U postgres -d registry -f backup.sql

OpenSSL

Install Complier Tools

sudo apt update
sudo apt install build-essential checkinstall zlib1g-dev -y

Install Open SSL

cd /usr/local/src/
sudo wget --inet4-only https://www.openssl.org/source/openssl-1.1.1m.tar.gz --no-check-certificate

sudo tar -xf openssl-1.1.1m.tar.gz
cd openssl-1.1.1m
sudo ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib

sudo make
sudo make test
sudo make install
cd /etc/ld.so.conf.d/
sudo nano openssl-1.1.1m.conf

Insert the following line in openssl-1.1.1m.conf

/usr/local/ssl/lib

Save and Exit, run the following commands

sudo ldconfig -v
sudo mv /usr/bin/c_rehash /usr/bin/c_rehash.backup
sudo mv /usr/bin/openssl /usr/bin/openssl.backup

Set Envronment

sudo nano /etc/environment

Append the following:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/ssl/bin"

Save, and Exit

Load environment

source /etc/environment
echo $PATH

Check and verify

openssl version -a

Java

Install Java JDK 1.8 (Java licence required for production use, CoCCA is still testing Open JDK versions 1.8+)

sudo mkdir /usr/lib/jvm
cd /usr/lib/jvm
Direct download - https://www.oracle.com/java/technologies/downloads/
wget --inet4-only https://updates.coccaregistry.org/jdk-8u311-linux-x64.tar.gz --no-check-certificate

sudo tar -xvzf jdk-8u311-linux-x64.tar.gz

Append the following command to open the environment variables file.

sudo nano /etc/environment
JAVA_HOME="/usr/lib/jvm/jdk1.8.0_311"

Run from command line.

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_311/bin/java" 0
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0_311/bin/javac" 0
sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_311/bin/java
sudo update-alternatives --set javac /usr/lib/jvm/jdk1.8.0_311/bin/javac

Check Version

java -version

Resin

The http server used with CoCCA https://caucho.com

Before installing resin, install OpenSSL and the JDK

Recomended : Create a host name for your instance with an A record to match the server IP

cd /opt
sudo wget --inet4-only http://caucho.com/download/resin-4.0.66.tar.gz --no-check-certificate
tar -vzxf resin-4.0.66.tar.gz
cd resin-4.0.66
./configure --enable-64bit --prefix=/opt/resin/ --with-resin-root=/opt/resin --with-resin-log=/opt/resin/log --with-resin-conf=/opt/resin/conf

sudo make
sudo make install

Post Install Configuration:
Download the CoCCA lab jks from CoCCA ( needed for EPP and https ).

cd /opt/resin/conf/keys/
sudo wget --inet4-only https://updates.coccaregistry.org/star_coccaregistry_org.jks --no-check-certificate

Download the latest CoCCA ROOT.war file

cd /opt/resin/webapps/
sudo wget --inet4-only https://updates.coccaregistry.org/ROOT.war --no-check-certificate

Delete default resin.xml and download resin config file for CoCCA:

cd /opt/resin/conf/
rm -fr resin.xml
sudo wget --inet4-only https://updates.coccaregistry.org/resin/resin.xml --no-check-certificate

Edit resin config file:

replace default IPs with your server IPs ( line 28 and 42 )
replace default host registry.example.tld with your host name (line 75 and 83 ). Note: If you have not created an A record yet, you may put the server IP in place of the host name.
insert postgreql password you created in postgesql section above ( line 92 )

sudo nano /opt/resin/conf/resin.xml

Get postgreSQL jdbc driver

cd /opt/resin/lib/
wget --inet4-only https://jdbc.postgresql.org/download/postgresql-42.3.3.jar --no-check-certificate

Start ( or restart ) resin and login to portal. If restart does not work, try stop then start.

/etc/init.d/resin stop | start | restart

Go to your host name URL- https://registry.example.tld ( or https://ipaddress - will take ±15-20 seconds to load )

Default credentials for lab db - registry_admin / h&6UQjJ3

letsencrypt

Optional The CoCCA lab jks downloaded above will enable https connections but with a browser warning. If you want a free https certificate to match your host name, we suggest https://letsencrypt.org

Tool - https://snapcraft.io/docs/installing-snapd

sudo snap install core; sudo snap refresh core
sudo snap install --classic certbot

Stop resin webserver to release port 80 and 443 temporarily.

/etc/init.d/resin stop

Request a new certificate

sudo certbot certonly --standalone

Create p12 (one long srting/command)

/usr/local/ssl/bin/openssl pkcs12 -export -name sslcertificate -in /etc/letsencrypt/live/registry.example.tld/fullchain.pem -inkey /etc/letsencrypt/live/registry.example.tld/privkey.pem -out registry.example.tld.p12

Create Java keystore and import p12 (one long string/command):

/usr/lib/jvm/jdk1.8.0_311/bin/keytool -importkeystore -destkeystore registry.example.tld.jks -srckeystore registry.example.tld.p12 -srcstoretype pkcs12 -alias sslcertificate

Move newly created jks to the resin keys folder

mv registry.example.tld.jks /opt/resin/conf/keys/registry.example.tld.jks

Edit resin config file to enable new http certificate:

sudo nano /opt/resin/conf/resin.xml

Add the path, jks file name and password for the custom jks created above (lines 45 & 46)

Start ( or restart ) resin and login to portal. If restart does not work, try stop then start.

/etc/init.d/resin stop | start | restart

Other

Set server time to UTC for RFC compliance:

sudo timedatectl set-timezone UTC

Ubunutu firewall basic configuration, handy commands:

sudo ufw enable | disable
sudo ufw status numbered ( see rules )
sudo ufw delete X ( delete a rule by number )
sudo ufw reload ( after rule changes )

sudo ufw enable
sudo ufw allow from "my trusted IP" to any port 22
sudo ufw allow from "my trusted IP" to any port 53
sudo ufw allow from any to any port 80
sudo ufw allow from any to any port 443
sudo ufw allow from any to any port 43
sudo ufw allow from any to any port 700

Secure from brute force/dictionary ssh attacks

sudo apt install fail2ban
