centos7设置logstash和filebeat为systemd启动

logstash

  cd /lib/systemd/system

  cat >  logstash.service <<EOF

  Description=logstash
  Wants=network-online.target
  After=network-online.target

  [Service]
  User=root
  ExecStart=/usr/local/logstash/bin/logstash -f /usr/local/logstash/bin/mysql-demo.yaml
  # 设置为掉线自动重启，进程强制杀掉后会自动重新启动
  Restart=always

  [Install]
  WantedBy=multi-user.target
  EOF

  systemctl daemon-reload
  systemctl enable logstash
  systemctl status logstash
  systemctl start  logstash
  systemctl status logstash
  journalctl  -f -u logstash

报错：logstash[544]: could not find java; set JAVA_HOME or ensure java is in PATH
