Logstash 5.x keeps starting and stopping....  
**Here is my conf:**  
input {  
tcp {  
port =\> 4560  
codec =\> json\_lines  
}  
beats {  
port =\> 5044  
codec =\> "json"  
}  
}  
output {  
if [type] == "biz"  
{  
elasticsearch  
{  
user =\> logstash\_internal  
password =\> changeme  
hosts =\> "localhost:9200"  
index =\> "business-index-%{+YYYY.MM.dd}"  
}  
}

```
else if [logenv]
{
	elasticsearch 
	{ 
		user => logstash_internal
		password => changeme
		hosts => "localhost:9200"
		index => "logstash-%{logenv}-%{+YYYY.MM.dd}"
	}
}

```

stdout{  
codec =\> rubydebug  
}  
}

**log**

God...This is caused by having an logstash.conf.bak under /etc/logstash/conf.d  
But I don't know how to close this topic.
