Install Xenforo CentOS 7.x How To Install Elasticsearch 7.x for Xenforo

What should I enter for username and password? Do I need to use HTTPS if the ES server is installed in the same server as centimin?

If you installed ES correctly the username and password were shown in the install log.

 

I think it's correctly installed.



But how can I retrieve the username and password? I can't use the HTTPS btw. It said connection problem with the server.

 

You are using version 7. That doesn't come with https (by default) so you don't need to use it.

ES8 supports https though.

 

Just checking in to confirm this is still working to install ElasticSearch 7.17.28 on AlmaLinux 9. Thank you once again for this resource, @Sunka!

Only one very minor issue with the commands in the guide:

Code (Text):

$ service elasticsearch start
Starting elasticsearch: /etc/init.d/elasticsearch: line 99: daemon: command not found

Of course, just use systemctl instead:

Code (Text):

$ systemctl start elasticsearch

 

I've successfully installed elasticsearch using this thread multiple times. However, I recently ran into an issue on an install where elasticsearch failed to start and I would get an error message along the lines of

java.lang.NoClassDefFoundError: Could not initialize class com.sun.jna.Native
Caused by: java.lang.ExceptionInInitializerError: Exception java.lang.UnsatisfiedLinkError: /tmp/elasticsearch-6278881121764626280/jna13378800042182009509.tmp: /tmp/elasticsearch-6278881121764626280/jna13378800042182009509.tmp: failed to map segment from shared object [in thread "main"]

Even though I had defined the tmp directory as before, it did not seem to use this command was attempting to use /tmp which meant i'd have to modify the permissions of tmp which i did not want to do.
I could not make a change in file user/group ownership that seemed to fix reading jvm.options
A workaround I found was to add the tmp directory command in /etc/sysconfig/elasticsearch
Adding

Code:

ES_TMPDIR=/home/elasticsearch

fixed the issue for me.

Hope this helps someone in the future, including myself.

 

Which Elasticsearch version?
