ELK中的logstash、kafka与filebeat的部署。

实战

搭建环境与各主机角色说明。

机器选择:睿江云平台
节点选择:广东G(VPC网络更安全、SSD磁盘性能高)
云主机配置:4核16G(4核8G也支持,但会有延时感)
网络选择:VPC虚拟私有云(VPC网络更安全、高效)
带宽:5M
系统版本:Centos7.6
云主机数量:5
软件版本:ELK 7.4.0、kafka 2.12-2.6.0

首先,下面为部署logstash的步骤。
a.步骤1
登陆logstash节点。ssh 到 192.168.0.6
b.步骤2
cd /opt/
wget https://artifacts.elastic.co/downloads/logstash/logstash-7.4.0.tar.gz
c.步骤3
tar -zxvf logstash-7.4.0.tar.gz
mkdir -p /opt/els/logs/logs
d.步骤4
vi /opt/logstash-7.4.0/config/logstash.yml

path.logs: /opt/els/logs/logs
path.config: /opt/logstash-7.4.0/conf.d/*.conf
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: "elastic"
xpack.monitoring.elasticsearch.password: "123456"
xpack.monitoring.elasticsearch.hosts: ["http://ES-node1:9200","http://ES-node2:9201","http://ES-node3:9202"]

e.步骤5
新建配置文件,配置文件作用为自定义日志格式。
vi /opt/logstash-7.4.0/config/demo.yml

input {
        beats {
                port => 5044
                type => syslog
        }
}

filter{
    grok{
        match => [ "message","%{TIMESTAMP_ISO8601:timestamp}" ]
}
    date {
        match => [ "timestamp", "yyyy-MM-dd HH:mm:ss" ]
        locale => "en"
        timezone => "+00:00"
        target => "@timestamp"}

    mutate{
        remove_field => ["host"]
        remove_field => ["agent"]
        remove_field => ["ecs"]
        remove_field => ["tags"]
        remove_field => ["fields"]
        remove_field => ["@version"]
        remove_field => ["input"]
        remove_field => ["log"]
    }
}

output {
        elasticsearch {
                hosts => ["http://ES-node1:9200"]
                user => "elastic"
                password => "123456"
                index => "test-log"
        }

}

f.步骤6
chown -R els:els /opt/logstash-7.4.0
g.步骤7
cd /opt/logstash-7.4.0/bin/
nohup ./logstash &

logstash启动成功

部署完logstash,接下来部署kafka,作为日志的中转、存储。以下为部署kafka的步骤。(亲测可用)

a.步骤1
登陆kibana主节点、副节点、副节点。ssh 到 192.168.0.3、192.168.0.4、192.168.0.5
b.步骤2
vi /etc/hosts

192.168.0.3 kafka
192.168.0.4 ES-node1
192.168.0.5 ES-node2
192.168.0.6 ES-master

c.步骤3
cd /opt/
wget https://mirror.bit.edu.cn/apache/kafka/2.6.0/kafka_2.12-2.6.0.tgz
tai -zxvf /kafka_2.12-2.6.0.tgz
d.步骤4
192.168.0.3配置如下:
vi /opt/kafka_2.12-2.6.0/config/zookeeper.properties

dataDir=/opt/kafka_2.12-2.6.0/zookeeper-data/data/
dataLogDir=/opt/kafka_2.12-2.6.0/zookeeper-data/logs
clientPort=2181
maxClientCnxns=0
initLimit=10
syncLimit=5
server.1=192.168.0.3:2888:3888
server.2=192.168.0.4:2888:3888
server.3=192.168.0.5:2888:3888

创建目录
mkdir -p /opt/kafka_2.12-2.6.0/zookeeper-data/data/
mkdir -p /opt/kafka_2.12-2.6.0/zookeeper-data/logs

192.168.0.4配置如下:

dataDir=/opt/kafka_2.12-2.6.0/zookeeper-data/data/
dataLogDir=/opt/kafka_2.12-2.6.0/zookeeper-data/logs
clientPort=2181
admin.enableServer=false
maxClientCnxns=0
initLimit=10
syncLimit=5
server.1=192.168.0.3:2888:3888
server.2=192.168.0.4:2888:3888
server.3=192.168.0.5:2888:3888

创建目录
mkdir -p /opt/kafka_2.12-2.6.0/zookeeper-data/data/
mkdir -p /opt/kafka_2.12-2.6.0/zookeeper-data/logs

192.168.0.5配置如下:

dataDir=/opt/kafka_2.12-2.6.0/zookeeper-data/data/
dataLogDir=/opt/kafka_2.12-2.6.0/zookeeper-data/logs
clientPort=2181
admin.enableServer=false
maxClientCnxns=0
initLimit=10
syncLimit=5
server.1=192.168.0.3:2888:3888
server.2=192.168.0.4:2888:3888
server.3=192.168.0.5:2888:3888

创建目录
mkdir -p /opt/kafka_2.12-2.6.0/zookeeper-data/data/
mkdir -p /opt/kafka_2.12-2.6.0/zookeeper-data/logs

需要修改的地方为ip地址不同
e.步骤5

cd /opt/kafka_2.12-2.6.0/
nohup bin/kafka-server-start.sh config/server.properties &

192.168.0.4操作如下:

创建成功即测试启动完毕

最后将部署filebeat到对应的主机上进行日志检控与收集。以下为部署filebeat的步骤。(亲测可用)

a.步骤1
登陆filebeat。ssh 到 192.168.0.2
b.步骤2
cd /opt/
wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.4.0-linux-x86_64.tar.gz

c.步骤3
tai -zxvf ./filebeat-7.4.0-linux-x86_64.tar.gz
d.步骤4
192.168.0.2配置如下:
vi /opt/ filebeat-7.4.0-linux-x86_64/filebeat.yml

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/httpd/access_log
  tags: ["C7-httpd-access_log"]
- type: log
  enabled: true
  paths:
   - /var/log/httpd/error_log
  tags: ["C7-httpd-error_log"]
filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: falseoutput.kafka:
  enabled: true
  hosts: ["192.168.0.3:9092"]
  topic: "test"
  required_acks: 1
processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~

e.步骤5
nohup /opt/filebeat-7.4.0-linux-x86_64/filebeat -e -c /opt/filebeat-7.4.0-linux-x86_64/filebeat.yml &

启动filebeat成功

到目前为止,企业级ELK项目是完整部署下来了。检验下是否有数据输出到kibana。
打开浏览器,登录http://192.168.0.6:5601/
账号与密码都是elastic
点击discover进入discover界面,就可以看到刚录取的数据

(温馨提示,本文档的ELK项目因各业务不同,给出的部署方案防火墙都处于关闭状态。具体防火墙配置按各自的业务需求自行配置哦~)

企业级ELK项目的部署已经告一段落,当前部署的ELK只需加大设备规模,足以应付绝大多数的业务需求。下篇文章中,小编将分享一些部署ELK中踩过的坑、稍微深入点的原理、知识点、ELK的使用注意点等等。
