I am very very new to ELK, I installed ELK version 5.6.12 on CentOS sever. Elasticsearch and Kibana works fine. But I cannot connect Logstash to Elastic search. I have set environment variable as  
export JAVA\_HOME=/usr/local/jdk1.8.0\_131  
export PATH=/usr/local/jdk1.8.0\_131/bin:$PATH

I run simple test as  
bin/logstash -e 'input { stdin { } } output { elasticsearch { host =\> localhost:9200 protocol =\> "http" port =\>  
"9200" } }'

I get following 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  
/etc/logstash/logstash.yml/log4j2.properties. Using default config which  
logs errors to the console

Simple "slash" mentioned in official documentation of Logstash works like following  
$bin/logstash -e 'input { stdin { } } output { stdout {} }'  
Hello  
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

Using default config which logs errors to the console  
The stdin plugin is now waiting for input: {  
"@version" =\> "1",  
"host" =\> "localhost",  
"@timestamp" =\> 2018-11-01T04:44:58.648Z,  
"message" =\> "Hello" }  
What could be the problem?

The error is fairly clear - it says it could not find `logstash.yml`, and recommends specifying the path using `--path.settings`. Modify your command to point at the `config` directory:

```
bin/logstash -e 'input { stdin { } } output { elasticsearch { host => localhost:9200 protocol => "http" port =>
"9200" } }' --path.settings config/
```

I got the same error but when I've specified the path for logstash.yml file using path.settings field, it ran as expected.

You can try following command:

`bin/logstash -e 'input { stdin { } } output { elasticsearch { host =&gt; localhost:9200 protocol =>; "http" port ="9200" } }' --path.settings /etc/logstash/`

Hope this works!
