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.

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

If you will face SKIP_IDENTIFIER_CHECK error, refer to this link.

• Go to http://localhost:8080/libreplan

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.

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 to 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.

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

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.
