Liferay is a portal framework that has been in development since 2000. It helps to streamline business processes by offering a single sign-on, web-based gateway for users to locate relevant content and easy access to commonly used applications. Liferay is focused on the user experience and allows customization through drag-and-drop portlets, themes and personal pages with a self-defined, friendly URL. The portal also offers control over access to sensitive information and functionality, collaborative tools such as instant messaging, message boards, blogs and wikis, and access to all the organization’s data, content, and information.
How to start/stop the servers?
The Stacks include a graphical tool to manage the servers easily. You can find the "manager-windows.exe", "manager-osx" or "manager-linux" tool in your installation directory. Using this tool, you can Start, Stop or Restart the servers and check the log files. You can click on the icon to start it.
On Windows: You can also start the Manager tool from shortcuts: Start -> Program Files -> BitNami Stack -> Manager tool
If you prefer, you can use the "ctlscript.sh" utility from the command line. This script is in the installation directory.
On OS X: You can start the Manager tool from the installation directory or you can use the "ctlscript.sh" utility from a Terminal.
host:~ user$ cd /Applications/application-version host:~ user$ ./ctlscript.sh start
$ cd ~/applicaton-version $ ./ctlscript.sh start
How to change the default URL?
The following steps describes how to configure your Liferay application to run in the root URL directly. Note that "installdir" refers to your installation directory. If you are using a Virtual Appliance, a BitNami Cloud Hosting instance or an AMI, the installation directory is "/opt/bitnami".
- Rename webapps/liferay to webapps/ROOT
$ sudo mv /installdir/apache-tomcat/webapps/ROOT/ /opt/bitnami/apache-tomcat/webapps/ROOT.backup $ sudo mv /installdir/apache-tomcat/webapps/liferay /opt/bitnami/apache-tomcat/webapps/ROOT
- Comment out the "portal.ctx" property in the /installdir/apache-tomcat/webapps/ROOT/WEB-INF/classes/portal-ext.properties file:
$ sudo sed -i 's/portal.ctx/#portal.ctx/g' /installdir/apache-tomcat/webapps/ROOT/WEB-INF/classes/portal-ext.properties
- If you are using a BitNami Cloud Hosting instance, edit the Apache configuration for Liferay ( /installdir/apps/liferay/conf/liferay.conf ) so it looks like this:
<Location /> ProxyPass ajp://localhost:8009/ </Location>
- Restart the services:
$ sudo /installdir/ctlscript.sh restart
How to create a full backup of Liferay?
Because BitNami stacks are self-contained, the simplest option for performing your backups is to copy or compress the BitNami Stack installation directory. To do so in a safe manner, you will need to stop all servers, so this method may not be appropriate if you have people accessing the application continously.
On Linux and OS X:
$ cd installdir $ ./ctlscript.sh stop $ cp -r installdir application-backup
Or you can create a tarball:
$ tar -czvf application-backup.tar.gz installdir
Or a zip file:
$ zip -r application-backup.zip installdir/*
To restore this backup you only need to uncompress the backup in the same location. It is important to use the same path that was used when the stack was originally installed.
For example if you have a backup in a Red Hat machine, you can copy it to an Ubuntu Linux machine (a different distro!) in the same location. Then start the servers and that’s all.
$ cd installdir $ ./ctlscript.sh start
You just need to be carefull to keep the same permissions for the files and folders. If you installed as root make sure that in the new machine you copy the files also as root. And this case, if you are also moving MySQL or PostgreSQL, you will need to create those users in the new machine (if they don't exist yet).
On Windows, you should follow the same process. Stop the servers using the shortcuts and copy the whole installation directory. To restore the system, copy the directory to a different Windows machine in the same location and follow these steps from a command prompt:
$ cd installdir $ serviceinstall.bat INSTALL
You can access your BitNami Application at the usual URL.
If you want to create only a database backup, check the following link for MySQL /Components/MySQL#How_to_create_a_database_backup or for PostgreSQL/Components/PostgreSQL#How_to_create_a_database_backup.3f
How to upgrade Liferay?
It is strongly recommended that you create a backup before starting the update process. If you have important data, it is advisable that you create and try to restore a backup to ensure that everything works properly.
There are two different ways to upgrade your application.
- If you want to upgrade the application and all Stack components PHP, Ruby, MySQL, Apache… You can follow the steps described at How to upgrade the full Stack migrating the data?
- In case you only want to upgrade the application code without modifying any other Stack components, you should follow the guide which is in the application page itself.
