简单搭建ELK

本文链接： https://blog.csdn.net/weixin_45754572/article/details/102603603
1、首先拉软件包,基于java语言开发首先配置java环境,centos7不用

2、首先安装elasticsearch-6.6.0.rpm

    rpm -ivh elasticsearch-6.6.0.rpm 

3、修改elasticsearch配置,并启动elasticsearch

        vim /etc/elasticsearch/elasticsearch.yml



     systemctl start elasticsearch

4、安装kibana

   rpm -ivh kibana-6.6.0-x86_64.rpm

5、修改kibana配置、并启动kibana

     vim /etc/kibana/kibana.yml
      systemctl start kibana

6、安装logstash过滤收集工具，和客户端有点相似

      rpm -ivh logstash-6.6.0.rpm

7、配置logstash、并启动logstash、记得监控日志时给日志加权限

      chmod 644 /var/log/messages

vim /etc/logstash/conf.d/system.conf

 systemctl start logstash

8、效果出现索引

二、原有基础上
1、监听nginx日志，配置nginx源、yum安装nginx,并启动nginx

vim /etc/yum.repos.d/nginx.repo
1
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
1
2
3
4
5
yum -y install nginx
1
systemctl start nginx
1
2、配置logstash配置、定义配置规则NIGNXACCESS，用来配置nginx过滤访问日志，记住加权限

cd /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-patterns-core-4.1.2/patterns/
1
vim nginx_access
1
URIPARAM1 [A-Za-z0-9$.+!’|(){},~@#%&/=:;_?-[]]
NGINXACCESS %{IPORHOST:client_ip} (%{USER:ident}|- ) (%{USER:auth}|-) [%{HTTPDATE:timestamp}] “(?:%{WORD:verb} (%{NOTSPACE:request}|-)(?: HTTP/%{NUMBER:http_version})?|-)” %{NUMBER:status} (?:%{NUMBER:bytes}|-) “(?:%{URI:referrer}|-)” “%{GREEDYDATA:agent}”

chmod 644 /var/log/nginx/access.log
1
vim /etc/logstash/conf.d/system.conf
1

3、重启logstash

systemctl restart logstash
1
4、重启logstash后访问nginx页面产生日志，nginx索引才会出现


4、要记住nginx日志格式是否开启，yum安装日志默认打开

vim /etc/nginx/nginx.conf
1

nginx页面最好做完之后，刷新几次产生日志
