I'm running Elasticsearch on an AIX 7.1.0.0 server, and just installed Logstash v2.1.0 today. Once I untar the installation file, I attempted to run the basic example command in the tutorial, and I'm getting a Java error. bin/logstash -e 'input { stdin { } } output { stdout { } }' Could not find any executable java binary. Please install java in your PATH or set JAVA\_HOME. But, Elasticsearch is running well on this server, and both PATH and JAVA\_HOME are set appropriately, or so it appears? # env PATH /usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/java8\_64/jre/bin:/usr/java8\_64/bin:/usr/java5/jre/bin:/usr/java5/bin # env JAVA\_HOME /usr/java8\_64 Am I overlooking something obvious? ---

I don't know AIX and we don't support it unfortunately. What does `java -version` report. ---

I vaguely recall that logstash (ELK stack in general) doesn't play well with IBM Java. You might need to install openjdk and point LS\_JAVA\_OPTS (on linux it is located in /etc/sysconfig/logstash, but I'm not sure about AIX) to it or alternatively export JAVA\_HOME. > -bash-4.2# ps -ef |grep ruby > root 24328 33523 0 20:42 pts/0 00:00:00 grep --color=auto ruby > logstash 34322 1 99 14:59 pts/0 15:48:58 /bin/java -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Djava.awt.headless=true -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt/logstash/heapdump.hprof -Djava.io.tmpdir=/var/lib/logstash -Xmx4096m -Xss2048k -Djffi.boot.library.path=/opt/logstash/vendor/jruby/lib/jni -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Djava.awt.headless=true -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt/logstash/heapdump.hprof -Djava.io.tmpdir=/var/lib/logstash -Xbootclasspath/a:/opt/logstash/vendor/jruby/lib/jruby.jar -classpath : -Djruby.home=/opt/logstash/vendor/jruby -Djruby.lib=/opt/logstash/vendor/jruby/lib -Djruby.script=jruby -Djruby.shell=/bin/sh org.jruby.Main --1.9 /opt/logstash/lib/bootstrap/environment.rb logstash/runner.rb agent -f /etc/logstash/conf.d -l /var/log/logstash/logstash.log -w 8 > -bash-4.2# which java > /usr/bin/java > -bash-4.2# /bin/java -version > openjdk version "1.8.0\_65" > OpenJDK Runtime Environment (build 1.8.0\_65-b17) > OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode) ---

Thanks -- my gut feeling was telling me that IBM Java may have had something to do with it, or an incompatibility with AIX. I went to look up OpenJDK, and it looks like they had to specially port it to AIX. I think I might try installing the Windows version of LogStash for starters, and maybe save the headache for now of adding to the Java environment on our AIX server. I may come back and revisit the OpenJDK option though. ---

I'm running into a lot of dead ends attempting to install OpenJDK for AIX, is it as straightforward as downloading and extracting the port from [http://openjdkpower.osuosl.org/OpenJDK/download/bootstrap/openjdk1.7.0-ppc-aix-port-linux-ppc64-b03.tar.bz2](http://openjdkpower.osuosl.org/OpenJDK/download/bootstrap/openjdk1.7.0-ppc-aix-port-linux-ppc64-b03.tar.bz2) ? I've done that, but the java executable in the resulting directory still doesn't seem to want to execute (even as root with appropriate permissions). ksh: bin/java: 0403-006 Execute permission denied. ---

Making progress with the OpenJDK option ... at least I've moved beyond the "Could not find any executable java binary" error. # bin/logstash -e 'input { stdin { } } output { stdout { } }' DEBUG: exec /usr/download/logstash-2.1.0/vendor/jruby/bin/jruby --1.9 -J-XX:+UseParNewGC -J-XX:+UseConcMarkSweepGC -J-Djava.awt.headless=true -J-XX:CMSInitiatingOccupancyFraction=75 -J-XX:+UseCMSInitiatingOccupancyOnly -J-XX:+HeapDumpOnOutOfMemoryError -J-XX:HeapDumpPath=/usr/download/logstash-2.1.0/heapdump.hprof -J-Xmx1g /usr/download/logstash-2.1.0/lib/bootstrap/environment.rb logstash/runner.rb agent -e input { stdin { } } output { stdout { } } bash: A file or directory in the path name does not exist. I've reviewed the logstash and [logstash.lib.sh](http://logstash.lib.sh) scripts, and the best I can tell, is maybe something is getting lost in the JRuby execution? Maybe I'm missing an environment setting there, and it's not able to find a required file?

No, the error you are getting is due to Java not able to find your CA. I never ran into this running on RHEL 6 and 7, so my guess is logstash looks at a specific location that doesn't exist on AIX (since it was never tested on AIX). You might be able to hack it by adding this argument to your logstash init.d file `-Djavax.net.ssl.trustStore` If this was my env, I would switch to Linux and call it a day. 🙂 ---

A couple of follow-up questions ... are there any flavors of Linux that won't work with LogStash (or the ELK stack)? If we have an opportunity to put this on ZLinux, is that going to be problematic, or is it close enough to RHEL, Ubuntu, etc.? Certainly ZLinux has to be closer than AIX. On the prior question about SSL certificates ... is there a way to just turn that off entirely when running LogStash? Just thinking about other possible workarounds. ---

Depends on which distribution of Linux you will be using. Sounds like you are an IBM shop. I believe IBM primarily ships Linux on Z with RHEL, Ubuntu and SUSE. You should be covered. > **[Support Matrix](https://www.elastic.co/support/matrix)** I'm not sure about bypassing the CA. If you look at the call stack, the top level call is from the bootstrap code, I doubt very much that you can bypass it. But I don't have the authoritative answer. > [@Russ](#): > > (root) at /usr/download/logstash-2.1.0/lib/bootstrap/environment.rb:57 [Next page](https://discuss.elastic.co/t/am-i-missing-an-installation-step/36222.md?page=2)
