Hello,
I have a hobby flask web app running the Elasticsearch service.
I am running Ubuntu 19.10 and followed the official installation instructions.
I have had several issues where the service won't start after restarting my computer.
I've made it a habit every time I reboot to check whether the service is running by typing the following in my terminal:
curl -X GET "localhost:9200/?pretty"
Typically it is a file/directory permission issues in the /var/log/elasticsearch directory OR
the elasticsearch/ directory being deleted.
So after through reading various posts, I know how to manually fix each of those issues:
If the directory is deleted, I create the directory and also create a gc.log file and set the permission of the directory containing it to 755.
If it's a permission issue, I just change that same directory's permissions to 755.
In both cases I can get it to work again, but I want to know how to prevent these issues from happening and not have to manually do it each time I reboot.
Is it my OS reverting these changes or is it some Elasticsearch setting that i'm not aware of that is responsible?
Thanks in advance!
