I cannot start logstash on my machine. Error message inside

[dona]

The following is the test command from the tutorial:

./logstash -e 'input { stdin { } } output { stdout {} }'

The following is the error.

WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path //usr/share/logstash/config/log4j2.properties. Using default config which logs to console

As for the error message part that says:

Path "/usr/share/logstash/data" must be a writable directory. It is not writable.

The directory is owned and writable by logstash.

Can anyone suggest any solutions?

@dona

Path "/usr/share/logstash/data" must be a writable directory. It is not writable.

The directory /usr/share/logstash must be owned by logstash and the permission of data directory should be 777

$ chown -R logstash.logstash /usr/share/logstash
$ chmod 777 /usr/share/logstash/data

Also check the user who owns logstash in /etc/default/logstash by default it is logstash.

I ran your commands and the ownership of /usr/share/logstash are fine. Initially the /etc/default/logstash was owned by root actually but I fixed it and it is now owned by logstash too. However, when I ran the same command as above now, I get nothing out of it. Not even an error message. The command just runs indefinitely blocking the command line. It's stuck somewhere.

Edit:
Nevermind, it worked. It just too a long time to set up the pipeline for some reason. Thank you
