问题
I am using the Apache Solr powered by BitNami EC2 AMI. Solr is running, but I'd like to change the startup configuration to increase the amount of memory allocated to JVM.
I have tried modifying the startup script at at /opt/bitnami/apache-solr/scripts/ctl.sh by modifying the following line:
SOLR="$JAVABIN -Dsolr.solr.home=$SOLR_HOME -Djetty.logs=$INSTALL_PATH/logs/ -Djetty.home=$INSTALL_PATH/ -jar $INSTALL_PATH/start.jar $INSTALL_PATH/etc/jetty.xml"
I've tried different permutations for the memory flags and none of them work (some of them cause the Solr server to fail to start at all, while others allow it to start but have no effect on the JVM memory allocated). This is what I've tried adding to the line:
-Xmx 1000 -Xms 8000
-Xms1000m -Xmx8000m
-Xms1000 -Xmx8000
-Xms 1000m -Xmx 8000m
What is the correct way of going about this?
回答1:
It turns out that the arguments needed to be at the start of the line. The following works:
SOLR="$JAVABIN -Xmx7168m -Xms1024m -Dsolr.solr.home=$SOLR_HOME -Djetty.logs=$INSTALL_PATH/logs/ -Djetty.home=$INSTALL_PATH/ -jar $INSTALL_PATH/start.jar $INSTALL_PATH/etc/jetty.xml"
