Hi everyone,
I'm having trouble starting Logstash in my Centos 7. I found several articles on Web, but not found a solution.
My configs:
**Oracle Java 8**
$ echo $JAVA\_HOME
$ /usr/bin/java
$java -version
java version "1.8.0\_172"
Java(TM) SE Runtime Environment (build 1.8.0\_172-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)
I installed the Logstash by yum following this article: [https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-centos-7](https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-centos-7)
But when run:
$ systemctl start logstash
Failed to start logstash.service: Unit not found
I try start manually Logstash:
$/usr/share/logstash/bin/logstash
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

[ERROR] 2018-07-03 16:43:51.955 [LogStash::Runner] Logstash - java.lang.IllegalStateException: Logstash stopped processing because of an error: (SystemExit) exit
Someone can help?

Centos 7 uses systemd, but the post-installation script of the logstash package erroneously tries to generate an `upstart` script, IIRC.
You can generate the `logstash.service` file for systemd with
```auto
sudo /usr/share/logstash/bin/system-install /etc/logstash/startup.options systemd`
```

Exactly, after running /usr/share/logstash/bin/system-install work for me.
