How to run Liferay on Resin Professional


Liferay is an awesome platform on which to build your website. It comes with TONS of functionality out of the box; pages, wiki, blog, forum, calendar, polls, messaging, social integration, mobile device optimization, etc.

Liferay really likes to "take over" your Resin server. It integrates Resin like a component of Liferay, rather than Liferay being an application that runs in Resin... Unfortunately this means that it appears to duplicate or invalidate some of Resin Pro's advanced features for scalability and failover... (I'm still learning Liferay and will post more on this topic later.)


We're going to use the Liferay Resin bundle as a starting point, but install Resin Professional and copy over some necessary files from the bundles Resin to Resin Pro.

Liferay likes to write files to the PARENT of the Resin ROOT directory, so the default installation of Resin in /user/local/share/resin, /var/resin, /etc/resin, /var/log/resin won't work. You need a dedicated Liferay directory in which Resin is installed as a subdirectory.

1. Setup a database for Liferay. I'm using MySQL and created a dedicated schema called "liferay" and a user "liferay" with password "liferay".

2. Download Liferay bundled with Resin. I've downloaded Liferay Portal 6.1 Community Edition 6.1 CE GA2 bundled with Resin

molson:Downloads paul$ ls -l 
-rw-r--r--@ 1 paul  staff  233381645 Jan 25 17:05

3. Download Resin. I've downloaded Resin Professional 4.0.34.

molson:Downloads paul$ ls -l 
-rw-r--r--  1 paul  staff  28445825 Jan 31 06:47

4. Extract the Liferay archive

molson:Downloads paul$ cd ..
molson:~ paul$ unzip Downloads/ 

5. Change directory into the Liferay directory. There will be a Resin Open Source directory, probably an older version of Resin than you downloaded. We'll delete this later, but leave it there for now.

molson:~ paul$ cd liferay-portal-6.1.1-ce-ga2/
molson:liferay-portal-6.1.1-ce-ga2 paul$ ls -l
total 24
drwxr-xr-x   3 paul  staff    102 Jul 31  2012 data
drwxr-xr-x   4 paul  staff    136 Jul 31  2012 license
-rw-r--r--@  1 paul  staff  12065 Jul 18  2012 readme.html
drwxr-xr-x  30 paul  staff   1020 Jul 31  2012 resin-4.0.29

6. Extract the Resin archive to this directory, so you'll now have 2 Resin installs in the Liferay directory now

molson:liferay-portal-6.1.1-ce-ga2 paul$ unzip ~/Downloads/ 

7. Change to the Resin install directory and compile the Resin native libraries to this directory

molson:liferay-portal-6.1.1-ce-ga2 paul$ cd resin-pro-4.0.34/
molson:resin-pro-4.0.34 paul$ ./configure --prefix=`pwd`
molson:resin-pro-4.0.34 paul$ make
molson:resin-pro-4.0.34 paul$ make install

8. Copy your Resin .license file to the licenses directory

molson:resin-pro-4.0.34 paul$ cp ~/Downloads/101011.license licenses/

9. Edit conf/

molson:resin-pro-4.0.34 paul$ vi conf/

10. Liferay needs a lot of memory, and in particular a lot of PermGen space. Find the jvm_args line, uncomment it, and it set similar to this (depending on your available memory):

jvm_args  : -Dfile.encoding=UTF-8 -Duser.timezone=GMT -Xmx2G -XX:MaxPermSize=1G

11. Create a directory named "app-inf" (in the Resin root directory, which should be your current directory if you're following along)

molson:resin-pro-4.0.34 paul$ mkdir app-inf/

12. Copy all files from the Liferay bundled Resin ext-lib/ directory to the new app-inf/ directory. This is important. Liferay needs a shared classloader to find themes and plugins. "app-inf/" is a special directory that the "app" cluster knows to use as a shared classloader.

molson:resin-pro-4.0.34 paul$ cp ../resin-4.0.29/ext-lib/* app-inf/

13. Change to the Resin webapps directory and delete the ROOT webapp

molson:resin-pro-4.0.34 paul$ cd webapps/
molson:webapps paul$ rm -rf ROOT/

14. Copy all webapps from the bundled Resin webapps directory to the Resin Pro webapps directory

molson:webapps paul$ cp -R ../../resin-4.0.29/webapps/* .

15. Change to ROOT/WEB-INF directory, and edit the file resin-web.xml

molson:webapps paul$ cd ROOT/WEB-INF/
molson:WEB-INF paul$ vi resin-web.xml

16. resin-web.xml should already have "PortalLoginModule" defined. Modify resin-web.xml to create a database pool and a mail session resource by adding <database> and a <mail> elements as shown:

<web-app xmlns="">
 <authenticator type="">
   <driver type="com.mysql.jdbc.Driver">
 <mail jndi-name="mail/MailSession">
   <properties><your smtp server>
mail.smtp.user=<your smtp user>
mail.smtp.password=<your smtp password>
mail.smtp.starttls.enable=true<your imap server>

17. Delete the bundled tmp and work directories if they exist

molson:WEB-INF paul$ rm -rf tmp/ work/

18. Create and edit a new file in the classes directory named

molson:WEB-INF paul$ vi classes/

19. Add the following properties to classes/ to tell Liferay about the database and mail resources you configured through Resin:

20. Resin Pro is now configured, so you can delete the Liferay bundled Resin

molson:classes paul$ cd ~/liferay-portal-6.1.1-ce-ga2/
molson:liferay-portal-6.1.1-ce-ga2 paul$ ls -l
total 24
drwxr-xr-x   3 paul  staff    102 Jul 31  2012 data
drwxr-xr-x   4 paul  staff    136 Jul 31  2012 license
-rw-r--r--@  1 paul  staff  12065 Jul 18  2012 readme.html
drwxr-xr-x  30 paul  staff   1020 Jul 31  2012 resin-4.0.29
drwxr-xr-x  35 paul  staff   1190 Feb  3 13:46 resin-pro-4.0.34
molson:liferay-portal-6.1.1-ce-ga2 paul$ rm -rf resin-4.0.29/

21. Startup Resin Pro

molson:liferay-portal-6.1.1-ce-ga2 paul$ ./resin-pro-4.0.34/bin/resinctl start
Resin/4.0.34 launching watchdog at
resinResin/4.0.34 started -server 'app-0' with watchdog at

22. Tail the Liferay log until you see Liferay started. This will take a while the 1st time, since Liferay has to create and populate the database.

molson:liferay-portal-6.1.1-ce-ga2 paul$ tail -f logs/liferay.2013-02-03.log 

(you should see)
14:07:16,395 INFO  [resin-24][ReleaseLocalServiceImpl:84] Create tables and populate with default data

23. Open a browser window to http://localhost:8080/. (Liferay has some cool way of automatically popping up a browser window, at least for me on OSX with Chrome, not sure how it does that!)

24. You can now proceed with the configuration wizard. Notice that if you did the database configuration right, the Database section should already show "JDBC Default JNDI Name jdbc/LiferayPool".
