logstash设置开机自启动

本篇文件前提是在centos7.6上使用rpm包安装的logstash，添加systemd方式启动。

#默认为rpm包安装，进行执行目录
cd /usr/share/logstash/bin/

#系统自带的system-install就是提供的开机自启动，查看文档说明
[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  #我们只看这一行，如果是rpm包，会有/etc/logstash/startup.options文件，进行文件，查看选项是否为各目录存放地址

新建logstash配置文件

#贴上一个简单的实列，作为systemd启动的配置文件
cat /etc/logstash/conf.d/kafka.conf     #conf.d目录下只能配置一个.conf文件
input { 

kafka{     #从kafka集群中拉取数据
        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

#启动logstash
systemctl start logstash
systemctl enable logstash


#观察日志查看是否启动成功
tail -f /var/log/logstash/logstash-plain.log
