Heritrix Configuration

1. Set the JAVA_HOME environment variable. The value should point to the JRE 11 Java installation.  For example, this variable might be set to /usr/local/java/jre

   export JAVA_HOME=/usr/local/java/jre

2. Set the HERITRIX_HOME environment variable. The value should be set to the main Heritrix directory, which is below the bin directory.

   export HERITRIX_HOME=/PATH/TO/HERITRIX

   For example, an installation of Heritrix with a bin directory located at /home/user/heritrix3.1/bin would be configured as follows.

   export HERITRIX_HOME=/home/user/heritrix3.1

3. Set execute permission on the Heritirix startup file.

   chmod u+x $HERITRIX_HOME/bin/heritrix

4. To change the amount of memory allocated to Heritrix (the Java heap size), set the JAVA_OPTS environmental variable.  The following example allocates 1GB of memory to Heritrix.

   export JAVA_OPTS=-Xmx1024M
