Centos7.6如何部署ELK日志分析系统

发布时间：2021-11-15 15:38:27 来源：亿速云 阅读：161 作者：小新 栏目：云计算

这篇文章将为大家详细讲解有关Centos7.6如何部署ELK日志分析系统，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

下载elasticsearch

创建elk用户并授权

useradd elk
chown -R elk:elk /home/elk/elasticsearch
chown -R elk:elk /home/elk/elasticsearch2
chown -R elk:elk /home/elk/elasticsearch3
mkdir -p /home/eladata
mkdir -p /var/log/elk
chown -R elk:elk /home/eladata
chown -R elk:elk /var/log/elk

主节点master

nohup npm run start &
curl -XPUT '192.168.2.67:9100/book'
访问192.168.2.67：9100 即可访问

下载kafka

修改配置文件如下

[root@localhost config]# pwd
/home/elk/kafka/config
[root@localhost config]# grep -v "^#" server.properties 
broker.id=0
listeners=PLAINTEXT://192.168.1.70:9092

kafka配置启动zookeeper

手动启动方式

[root@localhost bin]# pwd
/home/elk/kafka/bin
[root@localhost bin]#
./zookeeper-server-start.sh ../config/zookeeper.properties

systemctl 启动zookeeper

[root@localhost system]# pwd
/lib/systemd/system
[root@localhost system]# cat zookeeper.service

[root@localhost system]#
测试kafka

新建一个名字为test的topic

/kafka-topics.sh --create --zookeeper 192.168.1.70:2181 --replication-factor 1 --partitions 1 --topic test

查看kafka中的topic

./kafka-topics.sh --list  --zookeeper 192.168.1.70:2181

往kafka topic为test中 生产消息

./kafka-console-producer.sh --broker-list 192.168.1.70:9092 --topic test

在kafka topic为test中 消费消息

bin/kafka-console-consumer.sh --bootstrap-server 192.168.1.70:9092 --topic test --from-beginning

生产的消息，消费那边接受到即是ok的

目标机器安装filebeat

安装6.5版本的

[root@localhost filebeat]# pwd
/usr/local/filebeat
[root@localhost filebeat]# cat filebeat.yml 
filebeat.prospectors:
- type: log
  paths:
