服务器筹备
在这先列出各服务器节点,不便同学们在下文中对照节点查看相应内容
SpringBoot 我的项目筹备

IndexController
测试 Controller,用以打印日志进行调试
@Slf4j
@RestController
public class IndexController {@RequestMapping(value = "/index")

InputMDC

三个字段值

}
启动我的项目,拜访 /index
和/ero
接口,能够看到我的项目中生成了 app-collector.log
和error-collector.log
两个日志文件:
咱们将 Springboot 服务部署在 192.168.11.31 这台机器上。
Kafka 装置和启用
kafka 下载地址:
http://kafka.apache.org/downl…
kafka 装置步骤:首先 kafka 装置须要依赖与 zookeeper,所以小伙伴们先筹备好 zookeeper 环境(三个节点即可),而后咱们来一起构建 kafka broker。
## 解压命令:tar -zxvf kafka_2.12-2.1.0.tgz -C /usr/local/
## 改名命令:mv kafka_2.12-2.1.0/ kafka_2.12
## 进入解压后的目录,批改 server.properties 文件:vim /usr/local/kafka_2.12/config/server.properties
## 批改配置:broker.id=0
port=9092
host.name=192.168.11.51
advertised.host.name=192.168.11.51
log.dirs=/usr/local/kafka_2.12/kafka-logs
num.partitions=2
zookeeper.connect=192.168.11.111:2181,192.168.11.112:2181,192.168.11.113:2181
## 建设日志文件夹:mkdir /usr/local/kafka_2.12/kafka-logs
## 启动 kafka:/usr/local/kafka_2.12/bin/kafka-server-start.sh /usr/local/kafka_2.12/config/server.properties &
创立两个 topic
## 创立 topic
kafka-topics.sh --zookeeper 192.168.11.111:2181 --create --topic app-log-collector --partitions 1 --replication-factor 1
kafka-topics.sh --zookeeper 192.168.11.111:2181 --create --topic error-log-collector --partitions 1 --replication-factor 1
咱们能够查看一下 topic 状况
kafka-topics.sh --zookeeper 192.168.11.111:2181 --topic app-log-test --describe
能够看到曾经胜利启用了 app-log-collector
和error-log-collector
两个 topic
filebeat 装置和启用
filebeat 下载
cd /usr/local/software
tar -zxvf filebeat-6.6.0-linux-x86_64.tar.gz -C /usr/local/
cd /usr/local
mv filebeat-6.6.0-linux-x86_64/ filebeat-6.6.0
配置 filebeat,能够参考下方 yml 配置文件
vim /usr/local/filebeat-5.6.2/filebeat.yml
###################### Filebeat Configuration Example #########################
filebeat.prospectors:
- input_type: log
paths:
## app- 服务名称.log, 为什么写死,避免产生轮转抓取历史数据
- /usr/local/logs/app-collector.log
#定义写入 ES 时的 _type 值
document_type: "app-log"
multiline:
#pattern: '^\s*(\d{4}|\d{2})\-(\d{2}|[a-zA-Z]{3})\-(\d{2}|\d{4})' # 指定匹配的表达式(匹配以 2017-11-15 08:04:23:889 工夫格局结尾的字符串)pattern: '^\[' # 指定匹配的表达式(匹配以 "{ 结尾的字符串)negate: true # 是否匹配到
match: after # 合并到上一行的开端
max_lines: 2000 # 最大的行数
timeout: 2s # 如果在规定工夫没有新的日志事件就不期待前面的日志
fields:
logbiz: collector
logtopic: app-log-collector ## 按服务划分用作 kafka topic
evn: dev
- input_type: log
paths:
- /usr/local/logs/error-collector.log

topic: '%{[fields.logtopic]}'
partition.hash:
reachable_only: true
compression: gzip
max_message_bytes: 1000000
required_acks: 1
logging.to_files: true
filebeat 启动:
查看配置是否正确
cd /usr/local/filebeat-6.6.0
./filebeat -c filebeat.yml -configtest
## Config OK
启动 filebeat
/usr/local/filebeat-6.6.0/filebeat &
查看是否启动胜利
ps -ef | grep filebeat
能够看到 filebeat 曾经启动胜利
而后咱们拜访 192.168.11.31:8001/index 和 192.168.11.31:8001/err,再查看 kafka 的 logs 文件,能够看到曾经生成了 app-log-collector- 0 和 error-log-collector- 0 文件,阐明 filebeat 曾经帮咱们把数据收集好放到了 kafka 上。
logstash 装置
咱们在 logstash 的装置目录下新建一个文件夹
mkdir scrpit
而后 cd 进该文件,创立一个 logstash-script.conf
文件
cd scrpit
vim logstash-script.conf
## multiline 插件也能够用于其余相似的堆栈式信息,比方 linux 的内核日志。input {
kafka {
## app-log- 服务名称
topics_pattern => "app-log-.*"
bootstrap_servers => "192.168.11.51:9092"
codec => json
consumer_threads => 1 ## 减少 consumer 的并行生产线程数
decorate_events => true
#auto_offset_rest => "latest"
group_id => "app-log-group"
}
kafka {
## error-log- 服务名称
topics_pattern => "error-log-.*"
bootstrap_servers => "192.168.11.51:9092"
codec => json
consumer_threads => 1
decorate_events => true
#auto_offset_rest => "latest"
group_id => "error-log-group"
}
}
filter {
## 时区转换
ruby {code => "event.set('index_time',event.timestamp.time.localtime.strftime('%Y.%m.%d'))"
}
if "app-log" in [fields][logtopic]{
grok {
## 表达式, 这里对应的是 Springboot 输入的日志格局
match => ["message", "\[%{NOTSPACE:currentDateTime}\] \[%{NOTSPACE:level}\] \[%{NOTSPACE:thread-id}\] \[%{NOTSPACE:class}\] \[%{DATA:hostName}\] \[%{DATA:ip}\] \[%{DATA:applicationName}\] \[%{DATA:location}\] \[%{DATA:messageInfo}\] ## (\'\'|%{QUOTEDSTRING:throwable})"]
}
}
if "error-log" in [fields][logtopic]{
grok {
## 表达式
match => ["message", "\[%{NOTSPACE:currentDateTime}\] \[%{NOTSPACE:level}\] \[%{NOTSPACE:thread-id}\] \[%{NOTSPACE:class}\] \[%{DATA:hostName}\] \[%{DATA:ip}\] \[%{DATA:applicationName}\] \[%{DATA:location}\] \[%{DATA:messageInfo}\] ## (\'\'|%{QUOTEDSTRING:throwable})"]
}
}
}
## 测试输入到控制台:output {stdout { codec => rubydebug}
}
## elasticsearch:output {if "app-log" in [fields][logtopic]{
## es 插件
elasticsearch {
# es 服务地址
hosts => ["192.168.11.35:9200"]
# 用户名明码
user => "elastic"
password => "123456"
## 索引名,+ 号结尾的,就会主动认为前面是工夫格局:## javalog-app-service-2019.01.23
index => "app-log-%{[fields][logbiz]}-%{index_time}"
# 是否嗅探集群 ip:个别设置 true;http://192.168.11.35:9200/_nodes/http?pretty
# 通过嗅探机制进行 es 集群负载平衡发日志音讯
sniffing => true
# logstash 默认自带一个 mapping 模板,进行模板笼罩
template_overwrite => true
}
}
if "error-log" in [fields][logtopic]{
elasticsearch {hosts => ["192.168.11.35:9200"]
user => "elastic"
password => "123456"
index => "error-log-%{[fields][logbiz]}-%{index_time}"
sniffing => true
template_overwrite => true
}
}
}
启动 logstash
/usr/local/logstash-6.6.0/bin/logstash -f /usr/local/logstash-6.6.0/script/logstash-script.conf &
期待启动胜利,咱们再次拜访192.168.11.31:8001/err
能够看到控制台开始打印日志
ElasticSearch 与 Kibana
ES 和 Kibana 的搭建之前没写过博客,网上材料也比拟多,大家能够自行搜寻。
搭建实现后,拜访 Kibana 的治理页面192.168.11.35:5601
,抉择 Management -> Kinaba – Index Patterns
而后 Create index pattern
- index pattern 输出
app-log-*
- Time Filter field name 抉择 currentDateTime
这样咱们就胜利创立了索引。
咱们再次拜访192.168.11.31:8001/err
,这个时候就能够看到咱们曾经命中了一条 log 信息
外面展现了日志的全量信息
到这里,咱们残缺的日志收集及可视化就搭建实现了!
