As my computer has 32g memory, so I changed the jvm.options to increase the memory of logstash.
but after change the jvm.options , it promts the belowing error when run logstash.
root@EC2-ELK-IE-PROD-2 logstash]# /usr/share/logstash/bin/logstash --path.settings=/etc/logstash -r -w 8 -b 2000 -d
Invalid initial heap size: -Xms5g
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
When I googled, many people met this problem because of the 32bit java version.
But my java version is already 64bits.
[root@EC2-ELK-IE-PROD-2 elasticsearch]# java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
Are therre any guys can give me some advice? Thanks very much.
