Nginx日志配置
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" $status $request_time $upstream_response_time $request_length $bytes_sent $body_bytes_sent $gzip_ratio $connection_requests "$http_referer" "$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
运行nginx
安装java
参考文章：
http://blog.sina.com.cn/s/blog_13cc013b50102w01m.html#_Toc438402186
[root@bogon ~]# java -version
java version "1.8.0_65"
64-Bit Server VM (build 25.65-b01, mixed mode)
注意：logstash要求Java 8，不支持java9
https://www.elastic.co/guide/en/logstash/current/installing-logstash.html
安装logstash
# tar -xzvf logstash-5.5.2.tar.gz
# ls
logstash-5.5.2 logstash-5.5.2.tar.gz
# mkdir -p /usr/local/logstash
# mv logstash-5.5.2 /usr/local/logstash/
配置logstash
# vim /usr/local/logstash/logstash-5.5.2/logstash.conf
input { stdin {} }
output {
elasticsearch { hosts => ["192.168.1.101:9200"] }
stdout { codec => rubydebug }
}
说明：
input { stdin {} } 表示从标准输入中接收数据
192.168.1.101:9200 分别代表Elasticsearch搜索访问ip和监听端口
stdout { codec => rubydebug } 表示输出到控制台
参考链接：
https://www.elastic.co/guide/en/logstash/current/config-examples.html
运行logstash
# cd /usr/local/logstash/logstash-5.5.2/
# bin/logstash -f logstash.conf
……(略)
The stdin plugin is now waiting for input:
[2017-07-14T03:40:50,373][INFO ][logstash.agent ] Successfully started Logstash API endpoint {:port=>9600}
hello world
{
"@timestamp" => 2017-07-13T19:59:53.848Z,
"@version" => "1",
"host" => "0.0.0.0",
"message" => "hello world"
}
说明：启动后，输入上述带背景色内容 hello world，待控制台输出带黄色背景色内容后，在Elasticsearch中执行搜索，如下
GET /logstash-2017.07.13/_search
如上图，能搜索到输入数据，说明成功了
停止运行logstash
按CTRL + D键

安装Elasticsearch
略
安装kibana
# mkdir -p /usr/local/kibana
# tar -xvzf kibana-5.5.0-linux-x86_64.tar.gz
# mv kibana-5.5.0-linux-x86_64 /usr/local/kibana/
参考链接：
https://www.elastic.co/guide/en/kibana/current/targz.html
配置kibana
# cd /usr/local/kibana/kibana-5.5.0-linux-x86_64/config/
# vim kibana.yml
server.host: "192.168.1.104"
elasticsearch.url: "http://192.168.1.101:9200"
参考链接：
https://www.elastic.co/guide/en/kibana/current/settings.html
运行kibana
# cd /usr/local/kibana/kibana-5.5.0-linux-x86_64/
# ./bin/kibana
log [23:51:04.051] [info][status][plugin:kibana@5.5.0] Status changed from uninitialized to green - Ready

验证
浏览器中访问：http://192.168.1.104:5601/status
结果发现打不开
解决方法：停止防火墙
# systemctl stop firewalld.service
再次访问

配置索引模式（index pattern）
要使用Kibana至少需要配置一个索引模式(index pattern)。索引模式用于确认执行搜索和分析的Elasticsearch索引。
Index name or pattern
配置索引名称，或者索引模式。索引模式允许使用通配符 * 。比如 logstash-*
Time Filter field name
设置时间过滤器，方便在Discover页面中按时间筛选数据
Management -> Index Patterns -> Create Index Pattern，重新设置

安装filebeat
# tar -xvzf filebeat-5.5.2-linux-x86_64.tar.gz
# mkdir -p /usr/local/filebeat
# mv filebeat-5.5.2-linux-x86_64 /usr/local/filebeat/
配置
# vim /usr/local/filebeat/filebeat-5.5.2-linux-x86_64/filebeat.yml
配置日志文件路径
如上，可以指定具体的文件名，
- /usr/local/ngnix/logs/access.log
- /usr/local/ngnix/logs/error.log
也可以使用通配符，表示/usr/local/ngnix/logs/目录下，所有.log文件
- /usr/local/ngnix/logs/*.log
配置logstash输出
注意：hosts: 后面必须接一个空格，否则会报错
测试配置是否正确

# ./filebeat -configtest -e

input {
beats {
port => "9400"
}
}
filter{
grok {
match => {"message" => "%{IP:remote_addr} - %{USER:remote_user} [%{HTTPDATE:time_local}] "%{WORD:method} %{URIPATHPARAM:request} %{DATA:http_version}" %{NUMBER:status:int} %{NUMBER:request_time:float} %{NUMBER:upstream_response_time:float} %{NUMBER:request_length:int} %{NUMBER:bytes_sent:int} %{NUMBER:body_bytes_sent:int} %{DATA:gzip_ratio:float} %{NUMBER:connection_requests:int} "%{DATA:http_referer}" %{QUOTEDSTRING:http_user_agent} %{DATA:http_x_forwarded_for}"}
}
}
output {
elasticsearch { hosts => ["192.168.1.101:9200"] }
stdout { codec => rubydebug }
}

测试配置是否正确
# cd /usr/local/logstash/logstash-5.5.2/
# bin/logstash -f logstash.conf --config.test_and_exit
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

Configuration OK

运行logstash
说明：如果以--config.reload.automatic方式运行，已经在运行了，修改配置后，会自动重新加载配置，不需要重新运行logstash
# bin/logstash -f logstash.conf --config.reload.automatic

解决方法：防火墙开放端口
# firewall-cmd --permanent --zone=public --add-port=9400/tcp
success
# firewall-cmd --reload
success
