Environment (都需要Java环境,jdk){
elasticsearch kibana 安装nginx用以测试
logstash
}
1.首先拉取软件包,给予Java语言开发首选配置Java环境,CentOS 7 推荐4G运行内存
安装jdk环境,第一台机器安装elasticsearch
2.修改elasticsearch配置文件,设置网络主机,打开端口,并重启elasticsearch
注:关闭防火墙,看到9200和9300端口,代表此服务启动
3.安装kibana
修改kibana配置并启动kibana
启动,看到5601端口
4. 另一台logstash机器操作步骤
- 安装logstash过滤收集工具,类似客户端
2.配置logstash,并重启 logstash,注:监控日志时给日志加权限
添加系统配置文件
input{ file{ path => "/var/log/messages" type => "system_log" start_position => "beginning" } } output{ elasticsearch{ hosts => ["192.168.189.172:9200"] #elasticsearch主机的ip index => "system_log_%{+YYYY.MM.dd}" } }
注:9600为logstash搜索日志的端口
3.效果出现索引 网页输入ip:5601 显示kibana
Extend:原有基础上,监听nginx日志,并启动nginx(此步骤不唯一,可监听多个服务)
logstash机器
1.配置nginx源,yum安装nginx,并启动nginx(可导包解压,方法不唯一,根据实际操作)
vim /etc/yum.repos.d/nginx.repo
[nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/7/$basearch/ gpgcheck=0 enabled=1
下面步骤安装启动nginx
2.配置logstash配置文件,定义配置规则NIGNXACCESS,用来配置nginx过滤访问日志,记住加权限
cd /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-patterns-core-4.1.2/patterns/
vim nginx_access
URIPARAM1 [A-Za-z0-9$.+!*'|(){},~@#%&/=:;_?\-\[\]]* 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
vim /etc/logstash/conf.d/nginx.conf
input { file { path => "/var/log/nginx/access.log" #path => "/var/log/nginx/*.log" type => "nginx.log" start_position => "beginning" }}filter { grok { match => { "message" => "%{NGINXACCESS}" } }}output { elasticsearch { hosts => "
192.168.153.171:9200" index => "nginx_log-%{+
YYYY.MM.dd}" }}
systemctl restart logstash
3.切记nginx日志格式是否开启,yum安装日志默认打开
vim /etc/nginx/nginx.conf
4.nginx页面做好后,刷新几次产生日志
