centos7.6部署ELK集群（三）之logstash7.7.0部署

32.5. 部署logstash7.7.0（在主节点上操作）
32.6.1. 下载logstash7.7.0
Logstash 官方下载地址：https://www.elastic.co/cn/downloads/logstash

32.6.2. 解压至安装目录
tar –xvf logstash-7.7.0.tar.gz -C /vmdata/

32.6.3. 修改logstash-sample.conf配置文件
以kafka输入，es输出为例

input {
  kafka {
    bootstrap_servers => ["kafka1:9092,kafka2:9092,kafka3:9092"]
    group_id => "elk-consumer"
    auto_offset_reset => "latest"
    consumer_threads => 3
    decorate_events => true
    topics => ["elk_log_info"]
    type => "zc"
    codec => "json"
    max_partition_fetch_bytes => "5242940"
  }
}
output {
  elasticsearch {
    hosts => ["http://es1:9200","http://es2:9200","http://es3:9200"]
    index => "zc-logstash-%{+YYYY.MM.dd}"
  }
}

32.6.4. 将logstash安装目录授权给es用户
chown –R es:es /vmdata/logstash-7.7.0

32.6.5. 设置开机启动logstash服务
cd /etc/rc.d/init.d
vim logstash
文件内容如下:

#!/bin/bash
#chkconfig: 346 64 38
#description: logstash
#processname:logstash-7.7.0

export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera
export LOGSTASH_HOME=/vmdata/logstash-7.7.0

case $1 in
        start)
                su es<<!  
                cd $LOGSTASH_HOME
                nohup ./bin/logstash -f ./config/logstash-sample.conf &
!
                echo "logstash is started"
                ;;
        stop)
                pid=`netstat -antp|grep 9600|grep -v 'grep 9600'|awk '{print $7}'|awk -F'/' '{print $1}'`
                kill -9 $pid
                echo "logstash is stopped"
                ;;
        restart)
                pid=`netstat -antp|grep 9600|grep -v 'grep 9600'|awk '{print $7}'|awk -F'/' '{print $1}'`
                kill -9 $pid
                echo "logstash is stopped"
                sleep 5
                su es<<!
                cd $LOGSTASH_HOME
                nohup ./bin/logstash -f ./config/logstash-sample.conf &
!
                echo "logstash is restarted"
        ;;
    *)
        echo "start|stop|restart"
        ;;
esac
exit 0

32.6.6. 修改文件权限
chmod 777 logstash
添加服务并设置启动方式
chkconfig --add logstash
service logstash start　
32.6.7. 设置服务是否开机启动
