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。

[root@elk elk]# yum install java-1.8.0-openjdk -y

安装es

[root@elk elk]# yum localinstall elasticsearch-2.3.3.rpm -y
.....

修改防火墙,将9200、9300 端口对外开放

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 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

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

masquerade: no
forward-ports: port=80:proto=tcp:toport=5601:toaddr=
icmp-blocks:

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:

 

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

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

[root@elk ~]# firewall-cmd --reload

[root@elk ~]# firewall-cmd --list-all

masquerade: no
forward-ports: port=80:proto=tcp:toport=5601:toaddr=

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

[root@elk elk]# scp filebeat-1.2.3-x86_64.rpm root@rsyslog.test.com:/root/elk
[root@elk elk]# scp filebeat-1.2.3-x86_64.rpm root@nginx.test.com:/root/elk
[root@elk elk]# scp /etc/pki/tls/certs/logstash-forwarder.crt rsyslog.test.com:/root/elk
[root@elk elk]# scp /etc/pki/tls/certs/logstash-forwarder.crt nginx.test.com:/root/elk

四、客户端部署filebeat(在rsyslog、nginx客户端上操作)

  

  filebeat客户端是一个轻量级的,从服务器上的文件收集日志资源的工具,这些日志转发到处理到Logstash服务器上。该Filebeat客户端使用安全的Beats协议与Logstash实例通信。lumberjack协议被设计为可靠性和低延迟。Filebeat使用托管源数据的计算机的计算资源,并且Beats输入插件尽量减少对Logstash的资源需求。

4.1.(node1)安装filebeat,拷贝证书,创建收集日志配置文件

[root@rsyslog elk]# yum localinstall filebeat-1.2.3-x86_64.rpm -y
#拷贝证书到本机指定目录中
[root@rsyslog elk]# cp logstash-forwarder.crt /etc/pki/tls/certs/.
[root@rsyslog elk]# cd /etc/filebeat/
[root@rsyslog filebeat]# tree
.
├── conf.d
│   ├── authlogs.yml
│   └── syslogs.yml
├── filebeat.template.json
└── filebeat.yml 1 directory, 4 files

修改的文件有3个,filebeat.yml,是定义连接logstash 服务器的配置。conf.d目录下的2个配置文件是自定义监控日志的,下面看下各自的内容:

filebeat.yml

 

authlogs.yml  & syslogs.yml

 

修改完成后,启动filebeat服务

[root@rsyslog filebeat]# service filebeat start
Starting filebeat: [ OK ]
[root@rsyslog filebeat]# chkconfig filebeat on [root@rsyslog filebeat]# netstat -altp
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 localhost:25151 *:* LISTEN 6230/python2
tcp 0 0 *:ssh *:* LISTEN 5509/sshd
tcp 0 0 localhost:ipp *:* LISTEN 1053/cupsd
tcp 0 0 localhost:smtp *:* LISTEN 1188/master
tcp 0 0 rsyslog.test.com:51155 elk.test.com:commplex-main ESTABLISHED 7443/filebeat
tcp 0 52 rsyslog.test.com:ssh 192.168.30.65:10580 ESTABLISHED 7164/sshd
tcp 0 0 *:ssh *:* LISTEN 5509/sshd
tcp 0 0 localhost:ipp *:* LISTEN 1053/cupsd
tcp 0 0 localhost:smtp *:* LISTEN 1188/master

如果连接不上,状态不正常的话,检查下客户端的防火墙。

4.2. (node2)安装filebeat,拷贝证书,创建收集日志配置文件

[root@nginx elk]# yum localinstall filebeat-1.2.3-x86_64.rpm -y
[root@nginx elk]# cp logstash-forwarder.crt /etc/pki/tls/certs/.
[root@nginx elk]# cd /etc/filebeat/
[root@nginx filebeat]# tree
.
├── conf.d
│   ├── nginx.yml
│   └── syslogs.yml
├── filebeat.template.json
└── filebeat.yml 1 directory, 4 files

修改filebeat.yml 内容如下:

 

syslogs.yml & nginx.yml

 

修改完成后,启动filebeat服务,并检查filebeat进程

[root@nginx filebeat]# service filebeat start
Starting filebeat: [ OK ]
[root@nginx filebeat]# chkconfig filebeat on [root@nginx filebeat]# netstat -aulpt
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 *:ssh *:* LISTEN 1076/sshd
tcp 0 0 localhost:smtp *:* LISTEN 1155/master
tcp 0 0 *:http *:* LISTEN 1446/nginx
tcp 0 52 nginx.test.com:ssh 192.168.30.65:11690 ESTABLISHED 1313/sshd
tcp 0 0 nginx.test.com:49500 elk.test.com:commplex-main ESTABLISHED 1515/filebeat
tcp 0 0 nginx.test.com:ssh 192.168.30.65:6215 ESTABLISHED 1196/sshd
tcp 0 0 nginx.test.com:ssh 192.168.30.65:6216 ESTABLISHED 1200/sshd
tcp 0 0 *:ssh *:* LISTEN 1076/sshd

通过上面可以看出,客户端filebeat进程已经和 elk 服务器连接了。下面去验证。

五、验证,访问kibana http://192.168.30.67

5.1 设置下

查看下两台机器的系统日志:node1的

node2的nginx 访问日志

六、体验

  之前在学习rsyslog +LogAnalyzer,然后又学了这个之后,发现elk 不管从整体系统,还是体验都是不错的,而且更新快。后续会继续学习,更新相关的监控过滤日志方法,日志分析,以及使用kafka 来进行存储的架构。
