Elasticsearch has stopped and no longer works

4y555 · January 19, 2020, 10:52pm

Hi guys
I was using Elasticsearch (with the nextcloud), but the elastic just stopped after a while.
Try to install other versions or reinstall the same version, but it doesn't work.
Can you help me? Thank you very much!

CentOS Linux release 7.7.1908 (Core)
Php 7.3.13
Mysql 5.7.29
Nextcloud 17.0.2

elasticsearch-6.8.6.rpm
readonlyrest-1.18.10_es6.8.6.zip

[root@nextcloud ~]# sudo -u apache /usr/bin/php /var/www/html/occ fulltextsearch:check

I've tested several versions, updated everything, searched several blogs, but I can't solve the problem. It is really frustrating.

Can any kindness help me?

Please share what is in the Elasticsearch logs.

I think the error message is pretty clear, no?

Cannot parse file /etc/elasticsearch/readonlyrest.yml content. Cause: mapping values are not allowed here
in 'reader', line 6, column 16:
          auth_key: nextcloud:nextcloud
                  ^

You are using here a third party plugin ReadonlyRestPlugin which is not supported. You should either use the official package and its security features or ask the authors of the plugin you are using for help.

My 2 cents.

May be you should try though:

auth_key: "nextcloud:nextcloud"

4y555 · January 20, 2020, 10:51am

Hi David, how are you? Hope so.

I published the logs and then realized where the error was: there were two "spaces" in readonlyrest.yml, just where you pointed out.

Now it's running.

Can you help me with one more thing?

After indexing everything, it presented error 82/82 files.
How can I list all of these files?

dadoonet · January 20, 2020, 11:10am

I have no idea of what it means...
