logstash設置開機自啟動

本篇文件前提是在centos7.6上使用rpm包安裝的logstash，添加systemd方式啟動。

#默認為rpm包安裝，進行執行目錄
cd /usr/share/logstash/bin/

#系統自帶的system-install就是提供的開機自啟動，查看文檔說明
[root@db01 bin]# ./system-install --help

OPTIONSFILE: Full path to a startup.options file
OPTIONSFILE is required if STARTUPTYPE is specified, but otherwise looks first
in /usr/share/logstash/config/startup.options and then /etc/logstash/startup.options
Last match wins  #我們只看這一行，如果是rpm包，會有/etc/logstash/startup.options文件，進行文件，查看選項是否為各目錄存放地址

新建logstash配置文件

#貼上一個簡單的實列，作為systemd啟動的配置文件
cat /etc/logstash/conf.d/kafka.conf     #conf.d目錄下只能配置一個.conf文件
input { 

kafka{     #從kafka集群中拉取數據
		bootstrap_servers => ["10.0.0.200:9092,10.0.0.201:9092,10.0.0.202:9092"]
		group_id => "test"
		auto_offset_reset => "earliest"
		consumer_threads => "5"
		decorate_events => "false"
		topics => ["kafka"]
		type => "nginx_log"
		codec => json
	}
}
output {
stdout {}
      elasticsearch {
        hosts => "http://192.168.2.23:9200"
        manage_template => false
        index => "nginx-%{+yyyy.MM}"
      }
}

生成systemd

#生成systemd 
/opt/kafka/bin/kafka-server-start.sh -daemon /opt/kafka/config/server.properties

#啟動logstash
systemctl start logstash
systemctl enable logstash


#觀察日志查看是否啟動成功
tail -f /var/log/logstash/logstash-plain.log
