CentOS 7安装部署ELK 6.2.4
一、ELK介绍ELK是三款开源软件的缩写,即:ElasticSearch + Logstash + Kibana。这三个工具组合形成了一套实用、易用的监控架构,可抓取系统日志、apache日志、nginx日志、mysql日志等多种日志类型,目前很多公司用它来搭建可视化的集中式日志分析平台。
ElasticSearch:是一个分布式的RESTful风格的搜索和数据分析引擎,同时还提供了集中存储功能,它主要负责将logstash抓取来的日志数据进行检索、查询、分析等。
Logstash:日志处理工具,负责日志收集、转换、解析等,并将解析后的日志推送给ElasticSearch进行检索。
Kibana:Web前端,可以将ElasticSearch检索后的日志转化为各种图表,为用户提供数据可视化支持。
Filebeat:轻量型日志采集器,负责采集文件形式的日志,并将采集来的日志推送给logstash进行处理。
Winlogbeat:轻量型windows事件日志采集器,负责采集wondows的事件日志,并将采集来的日志推送给logstash进行处理。
二、部署环境
由于我这边是测试环境,所以ElasticSearch + Logstash + Kibana这三个软件我都是装在一台机器上面,如果是生产环境,建议分开部署,并且ElasticSearch可配置成集群方式。
IP:192.168.2.207(ELK服务器,CentOS 7)
IP:192.168.2.203(filebeat,nginx服务器,CentOS 7)
IP:192.168.2.204(filebeat,apache服务器,CentOS 7)
IP:192.168.2.206(winlogbeat,windows 10)
三、安装前的准备工作
1、关闭 selinux 和防火墙(这里暂时关闭iptables,部署完成后再开启)
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
sed -i 's/SELINUXTYPE=targeted/#&/' /etc/selinux/config
setenforce 0# 可以设置配置文件永久关闭
systemctl stop firewalld.service
2、安装配置iptables
yum -y install iptables iptables-services
vim /etc/sysconfig/iptables # 添加如下端口策略
-A INPUT -p tcp -m state --state NEW -m tcp --dport 9200 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 5601 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 5044 -j ACCEPT
启动iptables
systemctl start iptables.service
systemctl enable iptables.service # 将iptables加入开机启动
查看iptables状态
systemctl status iptables.service
重启系统
reboot# 更改selinux需要重启系统才会生效
3、安装java 8及相关软件
yum -y install vim wget java java-devel
查看java版本
java -version

4、下载ELK及相关软件
ELK服务器需下载
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.rpm
wget https://artifacts.elastic.co/downloads/kibana/kibana-6.2.4-x86_64.rpm
wget https://artifacts.elastic.co/downloads/logstash/logstash-6.2.4.rpm
Linux节点服务器需下载
wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.2.4-x86_64.rpm
windows节点服务器需下载
http://i2.运维网.com/images/blog/201806/04/cef46c7b51c6dfbee7a5e334ede2485b.png
四、安装配置ELK
1、yum方式安装ELK
yum localinstall -y elasticsearch-6.2.4.rpm
yum localinstall -y kibana-6.2.4-x86_64.rpm
yum localinstall -y logstash-6.2.4.rpm
2、创建ELK存放数据和日志目录
mkdir -pv /data/elasticsearch/{data,logs}
mkdir -pv /data/logstash/{data,logs}
chown -R elasticsearch.elasticsearch /data/elasticsearch/
chown -R logstash.logstash /data/logstash/
3、修改ELK配置文件
vim /etc/elasticsearch/elasticsearch.yml
path.data: /data/elasticsearch/data
path.logs: /data/elasticsearch/logs
network.host: 0.0.0.0
http.port: 9200
vim /etc/logstash/logstash.yml
path.data: /data/logstash/data
path.logs: /data/logstash/logs
vim /etc/logstash/conf.d/logstash.conf# 添加如下内容
input {
beats {
port => 5044
codec => plain {
charset => "UTF-8"
}
}
}
output {
elasticsearch {
hosts => "127.0.0.1:9200"
manage_template => false
index => "%{[@metadata]}-%{+YYYY.MM.dd}"
document_type => "%{[@metadata]}"
}
}
vim /etc/kibana/kibana.yml
server.port: 5601
server.host: "192.168.2.207"
elasticsearch.url: "http://localhost:9200"
4、安装配置nginx
安装nginx和http用户认证工具
yum -y install epel-release
yum -y install nginx httpd-tools
修改nginx配置
cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak
vim /etc/nginx/nginx.conf
把下图中这一段注释掉
http://i2.运维网.com/images/blog/201806/04/1190cbfdef7ba80319c1f3a69254e9e0.png
vim /etc/nginx/conf.d/kibana.conf# 添加如下内容
server {
listen 80;
server_name kibana;
auth_basic "Restricted Access";
auth_basic_user_file /etc/nginx/kibana-user;//http认证文件
location / {
proxy_pass http://192.168.2.207:5601;//代理的kibana地址
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
生成http用户认证文件,生成文件kibana-user,并添加用户henhh
htpasswd -cm /etc/nginx/kibana-user henhh
此处需要输入两遍密码
5、启动ELK和nginx
systemctl daemon-reload# 重新加载所有配置文件
systemctl start elasticsearch logstash kibana nginx# 启动ELK和nginx
systemctl enable elasticsearch logstash kibana nginx# 将ELK和nginx加入开机启动
systemctl status elasticsearch logstash kibana nginx#查看ELK和nginx启动状态
查看端口是否已监听
http://i2.运维网.com/images/blog/201806/04/87e4d8400e0b65867719bc13bfa6fdcf.png
6、查看elasticsearch状态
curl -XGET 'http://192.168.2.207:9200/_cluster/state/nodes?pretty'
http://i2.运维网.com/images/blog/201806/04/b553104b08f52a4cff7e6606a39b5995.png
查看elasticsearch的master
curl -XGET 'http://192.168.2.207:9200/_cluster/state/master_node?pretty'
curl -XGET 'http://192.168.2.207:9200/_cat/master?v'
http://i2.运维网.com/images/blog/201806/04/3b10dfd7de864daed075756e95d2e66a.png
查看健康状态
curl -XGET 'http://192.168.2.207:9200/_cat/health?v'
curl -XGET 'http://192.168.2.207:9200/_cluster/health?pretty'
http://i2.运维网.com/images/blog/201806/04/3e5fcfb6469d29a5e68a895f976b2eb3.png
对于这个健康状态green(绿色)为最好
五、Linux节点服务器安装配置filebeat
安装filebeat,进入到之前下载安装包的目录,执行yum方式安装
yum localinstall -y filebeat-6.2.4-x86_64.rpm
修改filebeat配置
vim /etc/filebeat/filebeat.yml
- type: log
enabled: true
- /var/log/*.log
- /var/log/messages
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.template.settings:
index.number_of_shards: 3
setup.kibana:
host: "192.168.2.207:5601"
#output.elasticsearch: //我们输出到logstash,把这行注释掉
#hosts: ["localhost:9200"] //这行也注释掉
output.logstash:
hosts: ["192.168.2.207:5044"]
启用nginx模块
filebeat modules enable nginx
修改nginx模块配置
vim /etc/filebeat/modules.d/nginx.yml
- module: nginx
access:
enabled: true
var.paths: ["/var/log/nginx/access.log*"]
error:
enabled: true
var.paths: ["/var/log/nginx/error.log*"]
启用apache模块
filebeat modules enable apache2
修改apache模块配置
vim /etc/filebeat/modules.d/apache2.yml
- module: apache2
access:
enabled: true
var.paths: ["/var/log/httpd/access_log*"]
error:
enabled: true
var.paths: ["/var/log/httpd/error_log*"]
启动filebeat
systemctl start filebeat
systemctl enable filebeat
systemctl status filebeat
六、windows节点服务器安装配置winlogbeat
解压winlogbeat-6.2.4-windows-x86_64.zip,以管理员方式运行PowerShell,进入到解压后的目录,执行.\install-service-winlogbeat.ps1来安装服务。如果报错提示在此系统上禁止脚本运行,那就执行PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-winlogbeat.ps1,便可安装成功。
http://i2.运维网.com/images/blog/201806/04/ac1cd7fccf8482bc394de01a2487c5ff.png
修改配置文件 :winlogbeat.yml
winlogbeat.event_logs:
- name: Application
ignore_older: 72h
- name: Security
- name: System
setup.template.settings:
index.number_of_shards: 3
setup.kibana:
host: "192.168.2.207:5601"
#output.elasticsearch: //我们输出到logstash,所以这行注释掉
#hosts: ["localhost:9200"] //这行也注释掉
output.logstash:
hosts: ["192.168.2.207:5044"]
logging.to_files: true
logging.files:
path: D:/winlogbeat/winlogbeat/Logs
logging.level: info
使用以下命令检查配置文件的正确性,出现Config OK说明配置文件正确。
.\winlogbeat.exe test config -c .\winlogbeat.yml -e
http://i2.运维网.com/images/blog/201806/04/6ea10f3c3405ba6d67659d3faa73d080.png
启动winlogbeat服务
打开service(服务),找到winlogbeat,启动它。
http://i2.运维网.com/images/blog/201806/04/2fc0ee824ae7d3cf5f6a325a5600e8c6.png
命令行启动方式,执行下面命令
Start-Service winlogbeat
七、创建索引模式
浏览器访问http://192.168.2.207,输入之前通过htpasswd认证的用户名和密码登陆kibana。
http://i2.运维网.com/images/blog/201806/04/fd6c734ca6d0f5b7e76195d9a32fce56.png
点击Management,然后点击Index Patterns,再点击Create index pattern
http://i2.运维网.com/images/blog/201806/04/fb5c8e5795250145685e805a04020970.png
输入filebeat-,然后点击Next step
http://i2.运维网.com/images/blog/201806/04/7c04f2f21fcc04da589846d75f88e393.png
选择@timestamp,然后点击Create index pattern
http://i2.运维网.com/images/blog/201806/04/23f077acca48631c73f6c032ca0d04f4.png
按照此方法再创建一个名为winlogbeat-的索引模式。
