Installation

Log onto server

ssh <root-username>@server.domain.tld

Create new user

sudo adduser <username>
sudo usermod -aG sudo <username>

Copy ssh public key to server

ssh-copy-id <username>@server.domain.tld

Or alternatively manually copy your public key to the server

sudo cat /home/username/.ssh/id_rsa.pub | ssh <username>@server.domain.tld 'cat - >> ~/.ssh/authorized_keys'

NOTE: we need to copy the root user's public key because that's the user running Bamboo

Update apt-get repo

sudo apt update

Install various dependencies

sudo apt-get install mailutils
sudo apt-get install unzip

Install Java 7

You have a few options here and I would recommend the first one, but follow the instructions carefully.

See option 2 in StackOverflow answer https://askubuntu.com/a/803616/292943

Automatic Installation #2

Easiest, but very insecure [not recommended] https://askubuntu.com/a/761527/292943

Manual Installation #1

See option 1 in StackOverflow answer https://askubuntu.com/a/803616/292943

Manual Installation #2

Manually install OpenJDK7 from Azul https://www.azul.com/downloads/zulu/zulu-linux/

Check Java Version

Check to make sure that 

$ java -version
java version "1.7.0_161"
OpenJDK Runtime Environment (IcedTea 2.6.12) (7u161-2.6.12-1)
OpenJDK 64-Bit Server VM (build 24.161-b01, mixed mode)

MySQL 5.7

Install MySQL

sudo apt-get install mysql-server

Configure MySQL

Add the following lines to /etc/alternatives/my.cnf using your favorite text editor.

[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

External Connections [optional]

If you need to allow external connections to MySQL then you'll need to edit the mysqld configuration.

/etc/mysql/mysql.conf.d/mysqld.cnf

Instead of skip-networking the default is now to listen only on

localhost which is more compatible and is not less secure.

bind-address = 127.0.0.1

bind-address = 0.0.0.0

Restart MySQL

sudo service mysql restart

Install Tomcat 7

https://www.liquidweb.com/kb/how-to-install-apache-tomcat-7-on-ubuntu-16-04/

  1. Create tomcat directory
mkdir /opt/tomcat
cd /opt/tomcat
  1. Find download https://tomcat.apache.org/download-70.cgi

Download zip file

wget http://mirrors.gigenet.com/apache/tomcat/tomcat-7/v7.0.91/bin/apache-tomcat-7.0.91.zip

unzip apache-tomcat-7.0.91.zip

Create new tomcat user

Configure tomcat-users.xml [optional]

This configuration can be used for future upgrades. Make sure the file is only readable by root and/or the user that runs Tomcat. Replace and with appropriate values. See Tomcat docs for more information (https://tomcat.apache.org/tomcat-7.0-doc/manager-howto.html#Configuring_Manager_Application_Access).

<tomcat-users>
  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <role rolename="manager-jmx"/>
  <role rolename="manager-status"/>
  <user username="<gui-username>" password="<gui-password>" roles="manager-gui"/>
  <user username="<script-username>" password="<script-password>" roles="manager-script"/>
</tomcat-users>

NOTE: Please don't use obvious passwords (i.e. tomcat, password, s3cret, etc) because your server will get exploited.

Install Tomcat 8

  • Tomcat 7 https://www.liquidweb.com/kb/how-to-install-apache-tomcat-7-on-ubuntu-16-04/
  • Tomcat 8 https://www.digitalocean.com/community/questions/how-to-access-tomcat-8-admin-gui-from-different-host

sudo groupadd tomcat

TODO Start Tomcat automatically

Also note that we're setting memory config in tomcat.service so we no longer need to edit $CATALINA_HOME/bin/setenv.sh

sudo vi /etc/systemd/system/tomcat.service

Deployment

Create database

mysql -u root -p -e 'create database openboxes default charset utf8;'
mysql -u root -p -e 'grant all on openboxes.* to 'openboxes'@'localhost' identified by "openboxes";'

Configuration

Create openboxes-config.properties file

mkdir ~/.grails
vi ~/.grails/openboxes-config.properties

Copy the following into ~/.grails/openboxes-config.properties

# Database connection settings
dataSource.username=openboxes
dataSource.password=<password>
dataSource.url=jdbc:mysql://localhost:3306/openboxes

TODO Advanced configuration

  • Email
  • Sentry
  • ??

Add environment variables to ~/.bashrc

export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export CATALINA_HOME=/opt/tomcat/apache-tomcat-7.0.91

Execute ~/.bashrc to setup environment

. ~/.bashrc

Ensure the correct Java version is running

sudo update-alternatives --config java
There is 1 choice for the alternative java (providing /usr/bin/java).

Download latest development verison

cd ~
wget http://bamboo.pih-emr.org:8085/browse/OPENBOXES-SDDEV-226/artifact/DJ/Latest-WAR/openboxes.war

Deploy WAR file

cp openboxes.war /opt/tomcat/apache-tomcat-7.0.91/webapps

Tail the log file and wait awhile (could take about 10 minutes to create the database)

tail -f /opt/tomcat/apache-tomcat-7.0.91/logs/catalina.out

Open Chrome and profit

Additional Configuration

In order to get rid of the port 8080 and enable HTTPs, a common solution is to run a web server in front of Tomcat.

Install Apache 2.2

sudo apt-get install apache2

NOTE: You can configure Tomcat to listen on port 80/443 and enable HTTPS.

Configure HTTPS

The easiest way to do this is to use Let's Encrypt (Certbot). See docs here https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04

Install Certbot for Apache

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-apache

Create new HTTPS certificate

Ensure that your domain is accessible before proceeding.

sudo certbot --apache -d <subdomain.domain.tld>

Configure automatic update of certificate

Configure mod_jk

sudo apt-get install libapache2-mod-jk

Enable mod_jk

sudo a2enmod mod_jk

Update workers.properties

workers.tomcat_home=/opt/tomcat/apache-tomcat-7.0.91
workers.java_home=/usr/lib/jvm/java-7-openjdk-amd64

Configure Tomcat server.xml

Uncomment the following line in server.xml

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

Configure Apache

Add the following line to all of your apache configuration in sites-enabled * /etc/apache2/sites-enabled/000-default.conf * /etc/apache2/sites-enabled/000-default-le-ssl.conf

JkMount /openboxes/* ajp13_worker
JkMount /manager/* ajp13_worker

Restart Apache

Restart Tomcat
