ELK日志分析平台（三）— kibana数据可视化、kibana监控、采集日志插件filebeat

1、kibana数据可视化——日志分析

[root@foundation50 network-scripts]# cd /mnt/pub/docs/elk/7.6/
[root@foundation50 7.6]# scp kibana-7.6.1-x86_64.rpm server4:    将安装包拷贝到server4上
[root@server4 ~]#  rpm -ivh kibana-7.6.1-x86_64.rpm   安装
[root@server4 ~]# cd /etc/kibana/
[root@server4 kibana]# vim kibana.yml  编辑配置文件

[root@server4 kibana]# systemctl start kibana.service  启动
[root@server4 kibana]# netstat -antlupe | grep :5601   端口为5601
tcp        0      0 172.25.50.4:5601        0.0.0.0:*               LISTEN      997        53471      4112/node

创建可视化

需要导入数据

然后再次创建可视化

可以将可视化保存

将可视化放到图形展示

示例2：用垂直条形图访问不同主机的访问量
创建可视化，选则垂直条形图

[root@server1 ~]# yum install -y httpd-tools  安装
[root@server2 ~]# yum install -y httpd-tools  安装
[root@server3 ~]# yum install -y httpd-tools  安装
[root@server1 ~]# ab -c1 -n 200 http://172.25.50.4/index.html  server1压测访问200条
[root@server2 ~]#  ab -c1 -n 300 http://172.25.50.4/index.html  server2压测访问300条
[root@server3 ~]#  ab -c1 -n 400 http://172.25.50.4/index.html   server3压测访问400条

2、kibana监控

发现不可用，提示需要启用xpack安全验证

[root@server1 ~]# cd /usr/share/elasticsearch/
[root@server1 elasticsearch]# bin/elasticsearch-certutil ca   输出文件
Please enter the desired output file [elastic-stack-ca.p12]:    回车
Enter password for elastic-stack-ca.p12 :   回车
[root@server1 elasticsearch]# bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12  生成证书
Enter password for CA (elastic-stack-ca.p12) :   回车
Please enter the desired output file [elastic-certificates.p12]:   回车
Enter password for elastic-certificates.p12 :   回车
[root@server1 elasticsearch]# cp elastic-certificates.p12 /etc/elasticsearch/ 拷贝证书到elasticsearch目录
[root@server1 elasticsearch]# chown elasticsearch elastic-certificates.p12
[root@server1 elasticsearch]# scp elastic-certificates.p12 server2:/etc/elasticsearch/  将证书拷贝到server2
elastic-certificates.p12                      100% 3451     4.5MB/s   00:00
[root@server2 elasticsearch]# chown elasticsearch elastic-certificates.p12
[root@server1 elasticsearch]# scp elastic-certificates.p12 server3:/etc/elasticsearch/  将证书拷贝到server3
elastic-certificates.p12                      100% 3451     4.5MB/s   00:00
[root@server3 elasticsearch]# chown elasticsearch elastic-certificates.p12
[root@server1 ~]# cd /etc/elasticsearch/
[root@server1 elasticsearch]# vim elasticsearch.yml    在文件最后添加如下参数 ， server2和server3进行同样的操作
xpack.security.enabled: true   激活xpack认证
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: /etc/elasticsearch/elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: /etc/elasticsearch/elastic-certificates.p12
[root@server1 elasticsearch]# systemctl restart elasticsearch.service   重启
[root@server1 ~]# cd /usr/share/elasticsearch/bin/   进入bin目录
[root@server1 bin]# ./elasticsearch-setup-passwords interactive   进入交互式设置密码
Please confirm that you would like to continue [y/N]y
Enter password for [elastic]:    输入密码，每个密码输入两次
Reenter password for [elastic]:     elastic为kibana的管理员用户，拥有所有权限
Enter password for [apm_system]:
Reenter password for [apm_system]:
Enter password for [kibana]:
Reenter password for [kibana]:
Enter password for [logstash_system]:
Reenter password for [logstash_system]:
Enter password for [beats_system]:
Reenter password for [beats_system]:
Enter password for [remote_monitoring_user]:
Reenter password for [remote_monitoring_user]:
[root@server4 ~]# cd /etc/kibana/
[root@server4 kibana]# vim kibana.yml   连接elaticsearch用户和密码设置

[root@server4 kibana]# systemctl restart kibana.service   重启

访问172.50.25.4:5601,需要用户名和密码

访问172.25.50.4:9000

访问172.25.50.4:9100,无法连接

解决方法如下：

[root@server1 ~]# cd /etc/elasticsearch/
[root@server1 elasticsearch]# vim elasticsearch.yml

[root@server1 elasticsearch]# systemctl restart elasticsearch.service   重启

访问：http://172.25.50.4:9100/?auth_user=elastic&auth_password=westos

logstash认证连接

[root@server4 ~]# cd /etc/logstash/conf.d/
[root@server4 conf.d]# vim apache.conf   编辑

[root@server4 conf.d]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/apache.conf   运行

[root@foundation50 network-scripts]# ab -c1 -n 100 http://172.25.50.4/index.html   压测100

kibana监控配置

在指定的es集群的节点上安装metricbeat

[root@foundation50 network-scripts]# cd /mnt/pub/docs/elk/7.6/
[root@foundation50 7.6]# scp metricbeat-7.6.1-x86_64.rpm  server1:
[root@server1 ~]# rpm -ivh metricbeat-7.6.1-x86_64.rpm  安装

在 Metricbeat 中启用并配置 Elasticsearch x-pack 模块

[root@server1 ~]# cd /etc/metricbeat/
[root@server1 metricbeat]# cd modules.d/   模块目录
couchdb.yml.disabled              php_fpm.yml.disabled
docker.yml.disabled               postgresql.yml.disabled
dropwizard.yml.disabled           prometheus.yml.disabled
elasticsearch-xpack.yml.disabled  rabbitmq.yml.disabled
elasticsearch.yml.disabled        redis.yml.disabled
envoyproxy.yml.disabled           sql.yml.disabled
etcd.yml.disabled                 stan.yml.disabled
golang.yml.disabled               statsd.yml.disabled
googlecloud.yml.disabled          system.yml
[root@server1 modules.d]# metricbeat modules enable elasticsearch-xpack  激活elasticsearch-xpack 模块
Enabled elasticsearch-xpack
[root@server1 modules.d]# vim elasticsearch-xpack.yml  编辑模块文件

配置 Metricbeat 以发送至监测集群
换句话说就是Metricbeat将监控本机的数据发送到那去

[root@server1 ~]# cd /etc/metricbeat
[root@server1 metricbeat]# vim metricbeat.yml  编辑metricbeat主配置文件

[root@server1 metricbeat]# systemctl enable --now metricbeat.service   启动

查看es平台，可以发现server1已经配置好，server2、server3用同样的方法配置

kibans节点日志采集插件——filebeat

官网
进入官网选择所需模块，按照官网配置

[root@foundation50 isos]# cd /mnt/pub/docs/elk/7.6/
[root@foundation50 7.6]# scp filebeat-7.6.1-x86_64.rpm server1:  拷贝filebeat到server1
[root@server1 ~]# rpm -ivh filebeat-7.6.1-x86_64.rpm  安装
[root@server1 ~]# cd /etc/filebeat/
[root@server1 filebeat]# cd modules.d/  模块 ，这里面有很多服务的日志模块
activemq.yml.disabled       ibmmq.yml.disabled     netflow.yml.disabled
apache.yml.disabled         icinga.yml.disabled    nginx.yml.disabled
auditd.yml.disabled         iis.yml.disabled       osquery.yml.disabled
aws.yml.disabled            iptables.yml.disabled  panw.yml.disabled
azure.yml.disabled          kafka.yml.disabled     postgresql.yml.disabled
cef.yml.disabled            kibana.yml.disabled    rabbitmq.yml.disabled
cisco.yml.disabled          logstash.yml.disabled  redis.yml.disabled
coredns.yml.disabled        misp.yml.disabled      santa.yml.disabled
elasticsearch.yml.disabled  mongodb.yml.disabled   suricata.yml.disabled
envoyproxy.yml.disabled     mssql.yml.disabled     system.yml.disabled
googlecloud.yml.disabled    mysql.yml.disabled     traefik.yml.disabled
haproxy.yml.disabled        nats.yml.disabled      zeek.yml.disabled现在我们监控整个es集群的日志
[root@server1 modules.d]# filebeat modules enable elasticsearch  激活elasticsearch模块
Enabled elasticsearch
[root@server1 modules.d]# vim elasticsearch.yml  编辑

[root@server1 ~]# cd /etc/filebeat
[root@server1 filebeat]# vim filebeat.yml

[root@server1 filebeat]# systemctl enable --now filebeat.service   启动

ES集群检索存入大量的数据会有问题，需要进行索引生命周期配置管理
