LibrePlan automatic installation
--------------------------------

Docker image
~~~~~~~~~~~~

The easiest way to have a working LibrePlan instance in no time is to use LibrePlan docker images.
Beside the classic Libreplan/Postgresql image, you'll also find a MySQL/MariaDB one.

See https://hub.docker.com/r/libreplan/libreplan/ for detailed information and instruction.

Ubuntu PPAs
~~~~~~~~~~~

There are Ubuntu PPAs for different versions (Precise, Trusty, Utopic and Vivid), you
can find more info in the following URL:
https://launchpad.net/~libreplan/+archive/ppa

Instructions::

  $ sudo add-apt-repository ppa:libreplan/ppa
  $ sudo apt-get update
  $ sudo apt-get install libreplan

.. TIP::

  If you do not have ``add-apt-repository`` command, you will need to install
  ``software-properties-common`` package before running the previous commands.
  You can do it with the following line::

    sudo apt-get install software-properties-common

.. WARNING::

  If you have memory problems review the section `Fix memory errors`_.

Debian packages
~~~~~~~~~~~~~~~

There are Debian packages for Wheezy and Jessie (i386 and amd64), you can download them
from: http://sourceforge.net/projects/libreplan/files/LibrePlan/

Instructions:

* Download the package::

    $ wget http://downloads.sourceforge.net/project/libreplan/LibrePlan/libreplan_1.4.1-1_amd64.deb

Logs
----

Since *LibrePlan 1.1.1* log system is configured automatically creating a new
folder under ``/var/log/tomcat8/`` with ``.war`` name. For example:
``/var/log/tomcat8/libreplan/``.

Inside this new directory there will be two files (``libreplan.log`` and
``libreplan-error.log``) that will be rotated every day.

Configure log directory
~~~~~~~~~~~~~~~~~~~~~~~

Anyway if you want to set manually LibrePlan log path you will have to
configure ``JAVA_OPTS`` variable in your server. This variable is configured in
different files depending on the distribution:

* Debian or Ubuntu: ``/etc/default/tomcat8``
* Fedora or openSUSE: ``/etc/tomcat8/tomcat8.conf``

Where you will need to add the next line::

  # Configure LibrePlan log directory
  JAVA_OPTS="${JAVA_OPTS} -Dlibreplan-log-directory=/my/path/to/libreplan/log/"

.. WARNING::

  You have to be sure that the user running Tomcat (usually ``tomcat8``) has
  permissions to write in the specified directory.


Fix printing in Debian Squeeze
------------------------------

Since LibrePlan 1.2 printing support is not working properly in Debian Squeeze.
To fix this issue, basically, you have to get a newer version of CutyCapt and
WebKit dependencies from Debian testing.

Instructions:

* Make sure stable remains the default distribution to pull packages from::

  # echo 'APT::Default-Release "stable";' >> /etc/apt/apt.conf

* Add a new repository to make testing packages available to ``apt-get``::

  # echo "deb http://ftp.debian.org/debian testing main" >> /etc/apt/sources.list

* Refresh package index::

  # apt-get update

* Fetch and install ``cutycapt`` (and its dependencies) from testing::

  # apt-get -t testing install cutycapt


Fix memory errors
-----------------

With the default parameters of Tomcat in the different distributions you could
have problems with Java memory.

After a while using LibrePlan you could see that some windows do not work and
the log shows a ``java.lang.OutOfMemoryError`` exception.

This exception could be caused because of two different issues:

* Heap space::

    java.lang.OutOfMemoryError: Java heap space

* PermGemp space (Permanent Generation, reflective data for the JVM)::

    java.lang.OutOfMemoryError: PermGen space

In order to avoid this problem you need to configure properly ``JAVA_OPTS``
variable in your server. This is configured in different files depending on the
distribution:

* Debian or Ubuntu: ``/etc/default/tomcat8``
* Fedora or openSUSE: ``/etc/tomcat8/tomcat8.conf``

The next lines show a possible configuration to fix the memory errors (the exact
values depends on the server features)::

  JAVA_OPTS="-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m"
  JAVA_OPTS="${JAVA_OPTS} -server -Djava.awt.headless=true"

Where the different parameters have the following meaning:

* ``-Xms``: Initial size of the Java heap
* ``-Xmx``: Maximum size of the Java heap
* ``-XX:PermSize``: Initial size of PermGen
* ``-XX:MaxPermSize``: Maximum size of PermGen

.. NOTE::

   Take into account that size of PermGen is additional to heap size.
   Since JDK8(b75) you will not see java.lang.OutOfMemoryError: PermGen space.
