CentOS 7下安装Logstash ELK Stack 日志管理系统
一、介绍
The Elastic Stack - 它不是一个软件,而是Elasticsearch,Logstash,Kibana 开源软件的集合,对外是作为一个日志管理系统的开源方案。它可以从任何来源,任何格式进行日志搜索,分析获取数据,并实时进行展示。像盾牌(安全),监护者(警报)和Marvel(监测)一样为你的产品提供更多的可能。
Elasticsearch:搜索,提供分布式全文搜索引擎
Logstash: 日志收集,管理,存储
Kibana :日志的过滤web 展示
Filebeat:监控日志文件、转发
二、测试环境规划图
环境:ip、主机名按照如上规划,系统已经 update. 所有主机时间一致。防火墙测试环境已关闭。下面是这次elk学习的部署安装
目的:通过elk 主机收集监控主要server的系统日志、以及线上应用服务日志。
三、Elasticsearch+Logstash+Kibana的安装(在 elk.test.com 上进行操作)
3.1.基础环境检查
[root@elk ~]# hostname elk.test.com [root@elk ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.30.67 elk.test.com 192.168.30.99 rsyslog.test.com 192.168.30.64 nginx.test.com
3.2.软件包
[root@elk ~]# cd elk/ [root@elk elk]# wget -c https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/rpm/elasticsearch/2.3.3/elasticsearch-2.3.3.rpm [root@elk elk]# wget -c https://download.elastic.co/logstash/logstash/packages/CentOS/logstash-2.3.2-1.noarch.rpm [root@elk elk]# wget https://download.elastic.co/kibana/kibana/kibana-4.5.1-1.x86_64.rpm [root@elk elk]# wget -c https://download.elastic.co/beats/filebeat/filebeat-1.2.3-x86_64.rpm
3.3.检查
[root@elk elk]# ls elasticsearch-2.3.3.rpm filebeat-1.2.3-x86_64.rpm kibana-4.5.1-1.x86_64.rpm logstash-2.3.2-1.noarch.rpm
服务器只需要安装e、l、k, 客户端只需要安装filebeat。
3.4.安装elasticsearch,先安装jdk,elk server 需要java 开发环境支持,由于客户端上使用的是filebeat软件,它不依赖java环境,所以不需要安装。

修改防火墙,将9200、9300 端口对外开放
[root@elk elk]# firewall-cmd --permanent --add-port={9200/tcp,9300/tcp} success [root@elk elk]# firewall-cmd --reload success [root@elk elk]# firewall-cmd --list-all public (default, active) interfaces: eno16777984 eno33557248 sources: services: dhcpv6-client ssh ports: 9200/tcp 9300/tcp masquerade: no forward-ports: icmp-blocks: rich rules:
3.5 安装kibana
[root@elk elk]# yum localinstall kibana-4.5.1-1.x86_64.rpm –y [root@elk elk]# systemctl enable kibana Created symlink from /etc/systemd/system/multi-user.target.wants/kibana.service to /usr/lib/systemd/system/kibana.service.

检查kibana服务运行(Kibana默认 进程名:node ,端口5601)
[root@elk elk]# netstat -nltp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 909/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1595/master tcp 0 0 0.0.0.0:5601 0.0.0.0:* LISTEN 11260/node
修改防火墙,对外开放tcp/5601
[root@elk elk]# firewall-cmd --permanent --add-port=5601/tcp Success [root@elk elk]# firewall-cmd --reload success [root@elk elk]# firewall-cmd --list-all public (default, active) interfaces: eno16777984 eno33557248 sources: services: dhcpv6-client ssh ports: 9200/tcp 9300/tcp 5601/tcp masquerade: no forward-ports: icmp-blocks: rich rules:
这时,我们可以打开浏览器,测试访问一下kibana服务器http://192.168.30.67:5601/,确认没有问题,如下图:
在这里,我们可以修改防火墙,将用户访问80端口连接转发到5601上,这样可以直接输入网址不用指定端口了,如下:
[root@elk elk]# firewall-cmd --permanent --add-forward-port=port=80:proto=tcp:toport=5601 [root@elk elk]# firewall-cmd --reload [root@elk elk]# firewall-cmd --list-all public (default, active) interfaces: eno16777984 eno33557248 sources: services: dhcpv6-client ssh ports: 9200/tcp 9300/tcp 5601/tcp masquerade: no forward-ports: port=80:proto=tcp:toport=5601:toaddr= icmp-blocks: rich rules:
3.6 安装logstash,以及添加配置文件
[root@elk elk]# yum localinstall logstash-2.3.2-1.noarch.rpm –y
生成证书
[root@elk elk]# cd /etc/pki/tls/ [root@elk tls]# ls cert.pem certs misc openssl.cnf private [root@elk tls]# openssl req -subj '/CN=elk.test.com/' -x509 -days 3650 -batch -nodes -newkey rsa:2048 -keyout private/logstash-forwarder.key -out certs/logstash-forwarder.crt Generating a 2048 bit RSA private key ...................................................................+++ ......................................................+++ writing new private key to 'private/logstash-forwarder.key' -----
之后创建logstash 的配置文件。如下:
[root@elk ~]# cat /etc/logstash/conf.d/01-logstash-initial.conf input { beats { port => 5000 type => "logs" ssl => true ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt" ssl_key => "/etc/pki/tls/private/logstash-forwarder.key" } } filter { if [type] == "syslog-beat" { grok { match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" } add_field => [ "received_at", "%{@timestamp}" ] add_field => [ "received_from", "%{host}" ] } geoip { source => "clientip" } syslog_pri {} date { match => [ "syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss" ] } } } output { elasticsearch { } stdout { codec => rubydebug } }
启动logstash,并检查端口,配置文件里,我们写的是5000端口
[root@elk conf.d]# systemctl start logstash [root@elk elk]# /sbin/chkconfig logstash on [root@elk conf.d]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 909/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1595/master tcp 0 0 0.0.0.0:5601 0.0.0.0:* LISTEN 11260/node tcp 0 0 0.0.0.0:514 0.0.0.0:* LISTEN 618/rsyslogd tcp6 0 0 :::5000 :::* LISTEN 12819/java tcp6 0 0 :::3306 :::* LISTEN 1270/mysqld tcp6 0 0 127.0.0.1:9200 :::* LISTEN 10430/java tcp6 0 0 ::1:9200 :::* LISTEN 10430/java tcp6 0 0 127.0.0.1:9300 :::* LISTEN 10430/java tcp6 0 0 ::1:9300 :::* LISTEN 10430/java tcp6 0 0 :::22 :::* LISTEN 909/sshd tcp6 0 0 ::1:25 :::* LISTEN 1595/master tcp6 0 0 :::514 :::* LISTEN 618/rsyslogd
修改防火墙,将5000端口对外开放。
[root@elk ~]# firewall-cmd --permanent --add-port=5000/tcp success [root@elk ~]# firewall-cmd --reload success [root@elk ~]# firewall-cmd --list-all public (default, active) interfaces: eno16777984 eno33557248 sources: services: dhcpv6-client ssh ports: 9200/tcp 9300/tcp 5000/tcp 5601/tcp masquerade: no forward-ports: port=80:proto=tcp:toport=5601:toaddr= icmp-blocks: rich rules:
3.7 修改elasticsearch 配置文件
查看目录,创建文件夹es-01(名字不是必须的),logging.yml是自带的,elasticsearch.yml是创建的文件,内如见下:
[root@elk ~]# cd /etc/elasticsearch/ [root@elk elasticsearch]# tree . ├── es-01 │ ├── elasticsearch.yml │ └── logging.yml └── scripts [root@elk elasticsearch]# cat es-01/elasticsearch.yml ---- http: port: 9200 network: host: elk.test.com node: name: elk.test.com path: data: /etc/elasticsearch/data/es-01
3.8 重启elasticsearch、logstash服务。
3.9 将 fiebeat安装包拷贝到 rsyslog、nginx 客户端上
