elasticserarch的用法
es-head相关说明： Node.js #es-head是用node.js开发的 npm #node.js的包管理工具 npm install #es-head项目里面的依赖下载下来 npm run start & #放在后台启动
安装elasticsearch
[root@oldboy ~]# rpm -ivh elasticsearch-6.6.0.rpm
[root@oldboy ~]# vim /usr/lib/systemd/system/elasticsearch.service
7 [Service] 在server段下写入第8行数据
8 LimitMEMLOCK=infinity
[root@oldboy ~]# grep -v "^#" /etc/elasticsearch/elasticsearch.yml
node.name: node-1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.mem ory_lock: true
network.host: 10.0.0.11,127.0.0.1
http.port: 9200
[root@oldboy ~]# systemctl daemon-reload

修改es配置文件支持跨域
[root@oldboy elasticsearch-head]# vim /etc/elasticsearch/elasticsearch.yml
最后两行添加如下参数
http.cors.enabled: true
http.cors.allow-origin: "*"
重启elasticsearch

刷新nginx访问页面，之后看下面页面，会出现nginx-6*开头的监控项
根据index索引添加监控项
添加之后的监控图像
这里以message为主添加监控筛选条件
如图
nginx日志转换成json格式
nginx转换成json操作步骤：
0.停止filebeat
systemctl stop filebeat
1.修改nginx日志格式为json
vim /etc/nginx/nginx.conf
log_format json '{ "time_local": "$time_local", '
'"remote_addr": "$remote_addr", '
'"referer": "$http_referer", '
'"request": "$request", '
'"status": $status, '
'"bytes": $body_bytes_sent, '
'"agent": "$http_user_agent", '
'"x_forwarded": "$http_x_forwarded_for", '
'"up_addr": "$upstream_addr",'
'"up_host": "$upstream_http_host",'
'"upstream_time": "$upstream_response_time",'
'"request_time": "$request_time"' '}';
access_log /var/log/nginx/access.log json;
2.清空原有nginx日志
>/var/log/nginx/access.log
3.检查nginx配置是否正确
nginx -t
4.重启nginx并访问
systemctl restart nginx
curl localhost/
5.检查日志是否为json
tail -a /var/log/nginx/access.log
6.修改filebeat配置文件，增加json配置
vim /etc/filebeat/filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/nginx/access.log
json.keys_under_root: true
json.overwrite_keys: true
output.elasticsearch:
hosts: ["10.0.0.101:9200"]
index: "nginx-json-%{[beat.version]}-%{+yyyy.MM.dd}"
setup.template.name: "nginx"
setup.template.pattern: "nginx-*"
setup.template.enabled: false
setup.template.overwrite: true
7.重启filebeat
systemctl restart filebeat
8.es-head查看是否生成新的索引
9.kiabina添加新生成的json的索引
10.过滤展示
监控tomcat日志
我的步骤：
yum install tomcat tomcat-webapps tomcat-admin-webapps tomcat-docs-webapp tomcat-javadoc -y
[root@oldboy opt]# vim /etc/tomcat/server.xml
删掉原来139行的数据，插入新的带有json格式的数据
138 prefix="localhost_access_log." suffix=".txt"
139 pattern="{"clientip":"%h","ClientUser":&quo t;%l","authenticated":"%u","AccessTime":"%t" ;,"method":"%r","status":"%s","SendBytes&qu ot;:"%b","Query?string":"%q","partner":"%{R eferer}i","AgentVersion":"%{User-Agent}i"}"/>
[root@oldboy filebeat]# systemctl start tomcat
[root@oldboy filebeat]# vim /etc/filebeat/filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/tomcat/localhost_access_log.*
json.keys_under_root: true
json.overwrite_keys: true
output.elasticsearch:
hosts: ["10.0.0.11:9200"]
index: "tomcat-json-%{[beat.version]}-%{+yyyy.MM.dd}"
setup.template.name: "tomcat"
setup.template.pattern: "tomcat-*"
setup.template.enabled: false
setup.template.overwrite: true
[root@oldboy tomcat]# systemctl start filebeat.service
老师的步骤
TOCMCAT日志收集步骤
1.正常安装配置tomcat
yum install tomcat tomcat-webapps tomcat-admin-webapps tomcat-docs-webapp tomcat-javadoc -y
2.启动访问tomcat测试
systemctl start tomcat
3.tomcat日志修改为json格式
#停止tomcat
systemctl stop tomcat
#清空原有tomcat日志
>/var/log/tomcat/localhost_access_log.2019-06-10.txt
#编辑tomcat配置文件139行，替换为json格式
vim /etc/tomcat/server.xml
pattern="{"clientip":"%h","ClientUser":"%l","authenticated":"%u","AccessTime":"%t","method":"%r","status":"%s","SendBytes":"%b","Query?string":"%q","partner":"%{Referer}i","AgentVersion":"%{User-Agent}i"}"/>
#重启tomcat
systemctl restart tomcat
#编辑filebeat配置文件
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/tomcat/localhost_access_log.*
json.keys_under_root: true
json.overwrite_keys: true
output.elasticsearch:
hosts: ["10.0.0.101:9200"]
index: "tomcat-json-%{[beat.version]}-%{+yyyy.MM.dd}"
setup.template.name: "tomcat"
setup.template.pattern: "tomcat-*"
setup.template.enabled: false
setup.template.overwrite: true
#重启filebeat
systemctl restart filebeat
多访问几次tomcat界面，让其产生访问日志
然后访问elasticsearch
[root@oldboy /]# vim /etc/filebeat/filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /root/elasticsearch.log ####这里的文件是老师发的
multiline.pattern: '^\['
multiline.negate: true
multiline.match: after
output.elasticsearch:
hosts: ["10.0.0.101:9200"]
index: "es-java-%{[beat.version]}-%{+yyyy.MM.dd}"
setup.template.name: "es"
setup.template.pattern: "es-*"
setup.template.enabled: false
setup.template.overwrite: true
[root@oldboy ~]# systemctl restart filebeat.service
操作步骤：
1.nginx修改为普通日志格式 2.清空nginx日志 3.修改filebeat配置文件，添加模块相关参数 4.使用filebeat命令打开模块开关 5.重启filebeat 6.访问nginx产生数据
注意：解决elasticsearch总是打不开网页的问题
