Logstash.service: Unit not found (CentOS 7)

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

But when run:

$ systemctl start logstash
Failed to start logstash.service: Unit not found

I try start manually 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
Could not find log4j2 configuration at path /usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console

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

sudo /usr/share/logstash/bin/system-install /etc/logstash/startup.options systemd`

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