This tutorial assumes you have a basic knowledge of virtualisation, Linux and the use of the command line. It will walk you through though and explain most things in detail.
I created this tutorial mainly for ColdFusion and CFML developers who create applications and need to test those applications on a wide variety of CFML platforms. Open BlueDragon in a virtual Ubuntu Server allows you to test and develop on a Linux platform while also checking for BlueDragon compatibility. As an added bonus, because we will be setting up a barebones, virtualised server with no graphical user interface, the resources used on your host machine will be much lower.
The basis of this server will be a barebones, Linux Server running Ubuntu Server 8.04. Web hosting will be covered by Apache Tomcat 6.18. It will require Sun Java 6. File transfers to the server will be done using FTP via ProFTPd and obviously our CFML server will be Open BlueDragon 1. We will also install the text based web browser ELinks to fetch some files that are not on the Ubuntu repositories.
You first need to download a copy of Ubuntu 8.04 LTS Server Edition from here http://www.ubuntu.com/getubuntu/download. The LTS means long term support, whereby the Ubuntu developer Canonical will continue to support this edition of the operating system until April 2013.
Start off by loading Sun xVM VirtualBox and pressing the New button.
Follow the wizard and when you reach VM Name and OS Type, give your new virtual machine a name. We will call ours Open BlueDragon Server. Make sure your Operating System is Linux and the version is Ubuntu.
The next screen, Memory can be left at the default of 386 MB.
The Virtual Hard Disk screen sets up the emulated hard drive for Ubuntu. Create a New disk. When given the option of Hard Disk Storage Type, I recommend selecting Dynamically expanding storage. When prompted for Size, you can reduce the default 8.00 GB down to 2.00 GB. Once you have Finished creating a new virtual hard disk, it should be now selected by default.
Press Next and review the Summary screen and then press Finish.
Now with your newly created virtual machine selected, press the Settings button. Select the CD/DVD-ROM tab. Select the Mount CD/DVD Drive checkbox and the ISO Image File radio. Push the browse folder icons on the right of the ISO Image File to bring up the Virtual Media Manager.
In the Virtual Media Manager select the Add button and browse to your Ubuntu Server download which should have a name similar to ubuntu-8.04.2-server-i386.iso. Once added to your CD/DVD Images, press Select and you will be returned to the Settings dialog.
Back in the Settings dialog, select the General tab and the Advanced sub-tab. I found I needed to select Extended Features: Enable PAE/NX otherwise Ubuntu would fail to boot after installation. If you wish you can select the Extended Features: Enable VT-x/AMD-V. You might also wish to deselect the Floppy from the Boot Order. If you want to add a description of your virtual machine, select the Description sub-tab.
Select the Network tab, Adapter 1. Make sure the Enabled Network Adapter is checked and then change the Attached To: pull down from NAT to Host Interface. Now if you have more than one host interface on your computer (most laptops have at least two, wired and wireless). Make sure the interface which you use to connect to the Internet is selected.
Once your settings are complete, press OK and then Start your virtual machine.
Two quick tips for users of VirtualBox. If you accidentally click the virtual machine window with your mouse and loose the pointer, press the right Ctrl key to have it returned. Also if your Ubuntu virtual machine window blanks out, this is due to the Ubuntu screen saver. Simply press the right arrow key when you have the VirtualBox window as your focused application and your shell should be returned.
Your virtual machine should now boot and you will quickly arrive at an Ubuntu language request screen. Select English and then press enter for Install Ubuntu Server.
After a few moments you will be taken to a text based install system. Again select English and press enter. Choose your country, territory or area.
On the Detect Keyboard Layout screen I used the arrow keys and select No to manually choose a keyboard. I found the automatic detection took more effort than the manual, but your use might vary.
The installer will now do its thing for a while.
When prompted for a hostname on the Configure the Network screen. Change the default from ubuntu to a name of your choice. I used opendb.
Choose your time zone or city.
On the Partition Disks screen, under Partitioning Method: select Guided – use entire disk. Select disk SCSI1. Accept the recommended settings by selecting Finish partitioning and write changes to disk. You will then be prompted to write changes to disk, accept Yes.
Ubuntu will now partition and resize your virtual hard drive and copy its files from the ISO CD/DVD image.
The next prompt will Set up users and passwords for your primary account that we will use to login to Ubuntu. Choose a Full name, either your own or something on the lines of Open BlueDragon. The Username can be anything of your choice, I will use openbdadmin. Then set a password that you will remember. This password will be used quite a fair bit later on.
Ignore and leave blank the HTTP Proxy information when prompted.
On the Software selection screen, do NOT select any software and instead just Continue.
Once the installation is complete, you will be prompted to restart the system, so Continue and the installer does this automatically.
Ubuntu will now start up and you will be taken to a login prompt. Login with your previously set username as login and password.
Now we will update the Ubuntu repository lists and available packages.
sudo apt-get -y update
When prompted your sudo password is the same as your login password. The sudo command allows you to run other commands temporarily as ROOT user.
Now we update your Ubuntu Server with the latest available, stable packages. I highly recommend you do this step otherwise you may encounter some networking bugs related to VirtualBox that have since been solved with software updates.
sudo apt-get -y upgrade
I suggest rebooting after the upgrade for the changes to take effect. You might also want to unmount the Ubuntu CD. You can do this by selecting the Devices, Unmount CD/DVD menu item from the virtual machine program window.
Once you have re-login we will need to install a text based web browser. I recommend ELinks.
sudo apt-get -y install elinks
Once installed, run ELinks and tell it to browse to the Tomcat website.
In ELinks we need to change a setting to make the browser look slightly more appealing. Press Esc S T to bring up the Terminal options dialog and under Frame handling: select VT 100 frames. Press V O to save these changes and exit the dialog.
Select Tomcat 6.x from the list on the left of the page. In ELinks you navigate between hyperlinks by using the arrow keys, and pressing enter to select.
On the download page, use the arrow keys to scroll down the hyperlinks until you see a light-blue heading 6.0.18 (this might be a different number if Tomcat is updated). Under it there should be the headings Binary Distributions * Core: select * tar.gz (pgp, md5) and this should start your Tomcat download. Just make sure you Save the file when prompted. Save to file ./apache-tomcat-6.0.18.tar.gz
Once your download is complete, press the Esc key on your keyboard to bring up the ELinks menu. F for File. X for Exit.
Back at the prompt we now need to install Sun’s Java.
sudo apt-get -y install sun-java6-jdk
When asked, agree to the licensing terms. Once Java has been installed we can now install Tomcat 6.
Should display our downloaded copy of Tomcat, apache-tomcat-6.0.18.tar.gz. We will move this archive to a more appropriate directory, install then run Tomcat.
A quick Linux tip for newbies, in shell instead of typing the full directory or file name, use the Tab key. For example for the command listed below you could type; sudo mv ap Tab /o Tab Enter cd /o Tab Enter
sudo mv apache-tomcat-6.0.18.tar.gz /opt/ cd /opt/
Uncompress Apache Tomcat archive.
sudo gunzip ./apache-tomcat-6.0.18.tar.gz
Unpack Apache Tomcat package.
sudo tar xvf apache-tomcat-6.0.18.tar
Rename Tomcat’s directory to something more simple.
sudo mv apache-tomcat-6.0.18 tomcat cd /opt/tomcat/
sudo elinks http://localhost:8080
If successful you should see a page with the header of The Mighty Tomcat – MEOW!
Now we need to download Open BlueDragon. In ELinks, Alt key F G to go to a new url.
Scroll down with the arrow keys until you see the heading Latest Stable Release (1.0.1). From there select the link J2EE Stardard WAR (18MB) Download and save the Open BlueDragon package.
Exit ELinks. Now we are going to modify Tomcat’s webapps directory structure.
sudo mv /opt/tomcat/webapps/ROOT/ /opt/tomcat/webapps/OLDROOT/
Now copy the downloaded Open BlueDragon package into the Tomcat webapps sub-directory, but while we copy it we will also give it a new name.
sudo cp openbd.war /opt/tomcat/webapps/ROOT.war
If Tomcat is running it will automatically detect the placement of ROOT.war in the webapps directory and create the new directory ROOT.
cd /opt/tomcat/webapps/ ls
We can test that Open BlueDragon is working by using ELinks.
With that all working we have a running Java based web server, running an open source CFML engine by default. But lets adjust some of Tomcat’s settings, such as the default port. Currently we have Tomcat running on port 8080 rather than the default HTTP port of 80.
We are going to use the nano text editor to change the Tomcat server configuration XML file. Nano is a very simple text editor that uses the CTRL key for most of its commands.
sudo nano /opt/tomcat/conf/server.xml
Ctrl _ 67 Enter should take you to line 67 which has the following
<Connector port=”8080″ protocol=”HTTP/1.1″
port="8080" to port="80"
Crtl x y Enter will save the changes.
We also need to modify one more configuration file to improve the performance of Tomcat. Otherwise you might find Open BlueDragon runs slower then expect. Edit this file.
sudo nano /opt/tomcat/bin/catalina.sh
Press Ctrl _ 72 Enter to take you to a blank line and add the following text.
# Increase Tomcat memory JAVA_OPTS="-Xms256m -Xmx256m"
Save the changes by pressing Ctrl x y Enter
Lets restart Tomcat to implement the changes.
sudo /opt/tomcat/bin/shutdown.sh sudo /opt/tomcat/bin/startup.sh elinks http://localhost/
Congratulations you now have Open BlueDragon, running as the default application on the Apache Tomcat server. You can reach BlueDragon’s administration page using this link.
The default password is admin. Now obviously a text based browser is not the best means of viewing the Administrator page. So quit ELinks and run this command.
Hopefully you should only have one network card listed and a Local Loopback. Your network card will be the first item listed usually as eth0. Look under the 2nd line for inet addr: and there should be a numeric IP address listed, in my case it is 192.168.0.5. Take note of your IP address.
In your favorite web browser on your host computer, point it to the following address…
(I would replace [noted ip address] with 192.168.0.5 to have http://192.168.0.5/bluedragon/adminstrator)
Other useful pages to note are listed below. These allow you to administrate and view statistics on the Tomcat web server. But both of them require you to create a custom user account.
Back in your VirtualBox window edit the following file.
sudo nano /opt/tomcat/bin/catalina.sh
Save the changes and edited the following so you can access the Tomcat management features.
sudo nano /opt/tomcat/conf/tomcat-users.xml
Replace these lines.
With the following but make sure you change the password.
<tomcat-users> <role rolename="manager"/> <user username="openbdadmin" password="[password of your choice]" roles="manager"/> </tomcat-users>
Save the changes, quit nano and restart Tomcat.
sudo /opt/tomcat/bin/shutdown.sh sudo /opt/tomcat/bin/startup.sh
Now with your web browser return to http://[noted ip address]/manager/status and use your new username and password. If successful you should be taken to a Server Status page where you can monitor your Tomcat server performance.
With your CFML web server up and running we now have to create a way to allow you to upload files to it. For this we will install a FTP server.
sudo apt-get install -y proftpd
When prompted at the ProFTPd configuration screen, select standalone.
Before we test the FTP server we need to adjust some settings.
sudo nano /etc/proftpd/proftpd.conf
In the file change.
UseIPv6 = on to UseIPv6 = off
ServerName = "Debian" to ServerName = "Open BlueDragon"
I like to adjust the default FTP server timeouts as when developing and testing. I find it annoying if I have to continuously be reconnected every time I transfer a file or navigate the directories.
TimeoutNoTransfer = 600 to TimeoutNoTransfer = 65256
TimeoutIdle = 1200 to TimeoutIdle = 65256
As this server is only being used internally we do not have to worry so much about security. So to keep things simple we just use the same user account that we use to login to shell.
User proftpd with User [your server login username]
If you want live file transfer status when connected to the FTP server, go to line 78 and replace.
# UseSendFile off with UseSendFile on
Go to the last line of the file at the very bottom of the file and type in the following to restrict all other user accounts from use in the FTP server.
# Restrict user logins <Limit LOGIN> AllowUser [your server login username] DenyALL </Limit> # Disable ident lookups to speed up connections identLookups off # Default folder on connection DefaultRoot /opt/tomcat/webapps/ROOT/
Quit and save the file.
We now need to claim ownership of the Tomcat webapps directory so when we connect with an FTP client we can modify folders and upload files.
sudo chown -vRf [your server login username] /opt/tomcat/webapps/
Now restart the FTP server for the new settings to come into effect.
sudo /etc/init.d/proftpd restart
Now using your favorite FTP program on your host machine, connect to the FTP on the virtual machine. You will use the same IP address as your web browser. So for me I would use the following settings…
Server Type: File Transfer Protocol or FTP
Login Type: normal
Finally we need to automatically run our new servers every time our virtual machine is rebooted. So back in your shell edit the following.
sudo nano /etc/rc.local
Add the following below. You do need to make sure it is all placed above the line exit 0.
# Start up Apache Tomcat web server /opt/tomcat/bin/startup.sh start # Start up ProFTPd FTP server /etc/init.d/proftpd start
Exit and save, then reboot your virtual server to test your new adjustments. Hopefully your Tomcat and FTP should now run at boot by themselves.
If you ever wish to shutdown the server.
sudo shutdown -P 0
Congratulations you now have a fully functional, virtual, CFML web server ready for you to play with. You don’t even need to login at shell for the server functionality to work.
