Hey,
I want install elasticsearch on my server (Linux RHEL-6Server-6.6.0.2.el6.x86_64) with jdk1.8.0_112 but I always the same error.
I try with the latest version of jdk (1.8.0.121) but the result is the same.
[elasticsearch@pcyy4aix ~]$ cd /logiciels/elasticsearch-5.3.0/bin
[elasticsearch@pcyy4aix bin]$ ./elasticsearch
Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create new native thread
Elasticsearch requires at least Java 8 but your Java version from /usr/bin/java does not meet this requirement
[elasticsearch@pcyy4aix bin]$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
In the script, I find
"$JAVA" -cp "$ES_CLASSPATH" org.elasticsearch.tools.JavaVersionChecker
if [ $? -ne 0 ]; then
echo "Elasticsearch requires at least Java 8 but your Java version from $JAVA does not meet this requirement"
exit 1
fi
And I try with the same variables and command line, no mistake
[elasticsearch@pcyy4aixbin]$ JAVA=/usr/bin/java
[elasticsearch@pcyy4aix bin]$ES_CLASSPATH=/logiciels/elasticsearch-5.3.0/lib/elasticsearch-5.3.0.jar:/logiciels/elasticsearch-5.3.0/lib/*
[elasticsearch@pcyy4aix bin]$ "$JAVA" -cp "$ES_CLASSPATH" org.elasticsearch.tools.JavaVersionChecker
[elasticsearch@pcyy4aixbin]$ echo $?
0
Thank you for your help.
Comes when you dont have sufficient memory , can you tell how much memory you have in system , you can check it via
free -m
If you have less than 4 GB then try changing the heap size in jvm.options from 2G (default) and make it 1G or 512M
Here is what I have:
[elasticsearch@pcyy4aix ~]$ free -m
total used free shared buffers cached
Mem: 15822 2400 13422 12 277 1342
-/+ buffers/cache: 780 15041
Swap: 1055 0 1055
I think I have enough memory
And how to make the change ?
I added
ES_JAVA_OPTS="-Xms8g -Xmx8g" ./bin/elasticsearch
In the script "elasticsearch" but I always have an error:
[elasticsearch@pcyy4aix bin]$ ./elasticsearch
./elasticsearch: fork: retry: Resource temporarily unavailable
./elasticsearch: fork: retry: Resource temporarily unavailable
./elasticsearch: fork: retry: Resource temporarily unavailable
./elasticsearch: fork: retry: Resource temporarily unavailable
I fund the file "jvm.options" in the folder "config".
I have change the parameters "Xms" and "Xmx" with "1g" or "8 g" and nothing.
Always the same error.
I found the problem.
I increase the number of processus of user "elasticsearch" of 2 to 200 to modify the file "/etc/security/limits.conf" and added the line
elasticsearch hard nproc 200
Now, I have a another problem:
[elasticsearch@pcyy4aix bin]$ ./elasticsearch

I fund this error's origin.
The folder of "elasticsearch" had the owner "root" instead of "elasticsearch".
Now, the process run:

But the connection at the URL "http://@IP:9200" don't answer.
Is it normal ?
