第1章 ELK简介

E:  elasticsearch   存储数据                java
L:  logstash        收集,过滤,转发,匹配 java
K:  kibana          过滤,分析,图形展示      java
F:  filebeat        收集日志,过滤             go

第2章: 传统日志分析需求

1.找出访问网站频次最高的 IP 排名前十
2.找出访问网站排名前十的 URL
3.找出中午 10 点到 2 点之间 www 网站访问频次最高的 IP
4.对比昨天这个时间段和今天这个时间段访问频次有什么变化
5.对比上周这个时间和今天这个时间的区别
6.找出特定的页面被访问了多少次
7.找出有问题的 IP 地址,并告诉我这个 IP 地址都访问了什么页面,在对比前几天他来过吗?他从什么时间段开
始访问的,什么时间段走了
8.找出来访问最慢的前十个页面并统计平均响应时间,对比昨天这也页面访问也这么慢吗?
9.找出搜索引擎今天各抓取了多少次?抓取了哪些页面?响应时间如何?
10.找出伪造成搜索引擎的 IP 地址

第4章 准备ES单机环境

cat >/etc/elasticsearch/elasticsearch.yml <<EOF
node.name: node-1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true

第5章 filebeat收集Nginx普通格式日志

0.更新系统时间

ntpdate time1.aliyun.com

1.安装nginx

[[email protected] ~]# cat /etc/yum.repos.d/nginx.repo 
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=0
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key

yum makecache fast
yum install nginx -y
systemctl start nginx

2.安装filebeat

rpm -ivh filebeat-6.6.0-x86_64.rpm
rpm -qc filebeat

3.配置filebeat

cp  /etc/filebeat/filebeat.yml /opt/
cat >/etc/filebeat/filebeat.yml<<EOF
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/nginx/access.log
output.elasticsearch:
  hosts: ["10.0.0.51:9200"]
EOF    

5.启动并检查

systemctl start filebeat
tail -f /var/log/filebeat/filebeat

6.查看日志结果

es-head查看

7.kibana添加

Management >> Index Patterns >> filebeat-6.6.0-2019.11.15 >>@timestamp >>create >> discover

第6章: filebeat收集Nginx的json格式日志

1.上面方案不完善的地方

所有日志都存储在message的value里,不能拆分单独显示

2.理想中的情况

可以把日志所有字段拆分出来
{
    $remote_addr : 192.168.12.254
    - : -
    $remote_user : -
    [$time_local]: [10/Sep/2019:10:52:08 +0800]
    $request: GET /jhdgsjfgjhshj HTTP/1.0
    $status : 404
    $body_bytes_sent : 153
    $http_referer : -
    $http_user_agent :ApacheBench/2.3
    $http_x_forwarded_for:-
}

3.目标

如何使nginx日志格式转换成我们想要的json格式

4.修改nginx配置文件使日志转换成json

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;

清除旧日志

> /var/log/nginx/access.log

检查并重启nginx

nginx -t 
systemctl restart nginx

5.nginx转换成json之后仍然不完善的地方

通过查看发现,虽然nginx日志变成了json,但是es里还是存储在message里仍然不能拆分

6.目标

如何在ES里展示的是json格式

7.修改filebeat配置文件支持json解析

cat >/etc/filebeat/filebeat.yml<<EOF
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/nginx/access.log
  json.keys_under_root: true
  json.overwrite_keys: true

output.elasticsearch:
  hosts: ["10.0.0.51:9200"]
EOF

7.删除ES里以前的索引

es-head >> filebeat-6.6.0-2019.11.15 >> 动作 >>删除 

8.重启filebeat

systemctl restart filebeat

第7章 filebeat自定义ES索引名称

1.理想中的索引名称

tail -f /var/log/nginx/www.log 

5.重启filebeat

systemctl restart filebeat 

6.检查redis是否有数据

redis-cli LRANGE nginx_access 0 -1 

7.配置logstash

yum install java -y 
cat >/etc/logstash/conf.d/redis.conf <<EOF
input {
  redis {
    host => "10.0.0.51"
    port => "6379"
    db => "0"
    key => "nginx_access"
    data_type => "list"
  }
  redis {
    host => "10.0.0.51"
    port => "6379"
    db => "0"
    key => "nginx_error"
    data_type => "list"
  }
}

filter {
  mutate {
    convert => ["upstream_time", "float"]
    convert => ["request_time", "float"]
  }
}

output {
   stdout {}
   if "access" in [tags] {
      elasticsearch {
        hosts => "http://10.0.0.51:9200"
        manage_template => false
        index => "nginx_access-%{+yyyy.MM}"
      }
    }
    if "error" in [tags] {
      elasticsearch {
        hosts => "http://10.0.0.51:9200"
        manage_template => false
        index => "nginx_error-%{+yyyy.MM}"
      }
    }
}
EOF

8.前台启动Logstash测试

删除ES旧的索引
/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/redis.conf

9.生成测试数据

yum install httpd-tools -y 
ab -c 100 -n 2000 www.mysun.com/www 
redis-cli LLEN nginx_access

10.如果数据正常传输给了es,在后台启动logstash

systemctl start logstash 

第18章 使用kafka作为缓存

1.配置hosts和密钥

cat >/etc/hosts<<EOF
10.0.0.51 db01
10.0.0.52 db02
10.0.0.53 db03
EOF
ssh-keygen
ssh-copy-id 10.0.0.52
ssh-copy-id 10.0.0.53

2.安装配置zookeeper

db01操作

cd /data/soft
tar zxf zookeeper-3.4.11.tar.gz -C /opt/
ln -s /opt/zookeeper-3.4.11/ /opt/zookeeper
mkdir -p /data/zookeeper
cp /opt/zookeeper/conf/zoo_sample.cfg /opt/zookeeper/conf/zoo.cfg
cat >/opt/zookeeper/conf/zoo.cfg<<EOF
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper
clientPort=2181
server.1=10.0.0.51:2888:3888
server.2=10.0.0.52:2888:3888
server.3=10.0.0.53:2888:3888
EOF
echo "1" > /data/zookeeper/myid
cat /data/zookeeper/myid
rsync -avz /opt/zookeeper* 10.0.0.52:/opt/
rsync -avz /opt/zookeeper* 10.0.0.53:/opt/

db02操作

mkdir -p /data/zookeeper
echo "2" > /data/zookeeper/myid
cat /data/zookeeper/myid

db03操作

mkdir -p /data/zookeeper
echo "3" > /data/zookeeper/myid
cat /data/zookeeper/myid

3.所有节点启动zookeeper

/opt/zookeeper/bin/zkServer.sh start

4.每个节点都检查

/opt/zookeeper/bin/zkServer.sh status

5.测试zookeeper

在一个节点上执行,创建一个频道

/opt/zookeeper/bin/zkCli.sh -server 10.0.0.51:2181
create /test "hello"

在其他节点上看能否接收到

/opt/zookeeper/bin/zkCli.sh -server 10.0.0.52:2181
get /test

6.安装部署kafka

db01操作

cd /data/soft/
tar zxf kafka_2.11-1.0.0.tgz -C /opt/
ln -s /opt/kafka_2.11-1.0.0/ /opt/kafka
mkdir /opt/kafka/logs
cat >/opt/kafka/config/server.properties<<EOF
broker.id=1
listeners=PLAINTEXT://10.0.0.51:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/opt/kafka/logs
num.partitions=1
num.recovery.threads.per.data.dir=1
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
log.retention.hours=24
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=10.0.0.51:2181,10.0.0.52:2181,10.0.0.53:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
EOF
rsync -avz /opt/kafka* 10.0.0.52:/opt/
rsync -avz /opt/kafka* 10.0.0.53:/opt/

db02操作

sed -i "s#10.0.0.51:9092#10.0.0.52:9092#g" /opt/kafka/config/server.properties
sed -i "s#broker.id=1#broker.id=2#g" /opt/kafka/config/server.properties

db03操作

sed -i "s#10.0.0.51:9092#10.0.0.53:9092#g" /opt/kafka/config/server.properties
sed -i "s#broker.id=1#broker.id=3#g" /opt/kafka/config/server.properties

7.前台启动测试

/opt/kafka/bin/kafka-server-start.sh  /opt/kafka/config/server.properties

8.验证进程

jps

9.测试创建topic

/opt/kafka/bin/kafka-topics.sh --create  --zookeeper 10.0.0.51:2181,10.0.0.52:2181,10.0.0.53:2181 --partitions 3 --replication-factor 3 --topic kafkatest

10.测试获取toppid

/opt/kafka/bin/kafka-topics.sh --describe --zookeeper 10.0.0.51:2181,10.0.0.52:2181,10.0.0.53:2181 --topic kafkatest

11.测试删除topic

/opt/kafka/bin/kafka-topics.sh --delete --zookeeper 10.0.0.51:2181,10.0.0.52:2181,10.0.0.53:2181 --topic kafkatest

12.kafka测试命令发送消息

1.创建命令

/opt/kafka/bin/kafka-topics.sh --create --zookeeper 10.0.0.51:2181,10.0.0.52:2181,10.0.0.53:2181 --partitions 3 --replication-factor 3 --topic  messagetest

2.测试发送消息

/opt/kafka/bin/kafka-console-producer.sh --broker-list  10.0.0.51:9092,10.0.0.52:9092,10.0.0.53:9092 --topic  messagetest

3.其他节点测试接收

/opt/kafka/bin/kafka-console-consumer.sh --zookeeper 10.0.0.51:2181,10.0.0.52:2181,10.0.0.53:2181 --topic messagetest --from-beginning

4.测试获取所有的频道

/opt/kafka/bin/kafka-topics.sh  --list --zookeeper 10.0.0.51:2181,10.0.0.52:2181,10.0.0.53:2181

13.测试成功之后,可以放在后台启动

/opt/kafka/bin/kafka-server-start.sh  -daemon /opt/kafka/config/server.properties

14.修改filebeat配置文件

cat >/etc/filebeat/filebeat.yml <<EOF
filebeat.inputs:
- type: log
  enabled: true 
  paths:
    - /var/log/nginx/access.log
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["access"]

- type: log
  enabled: true 
  paths:
    - /var/log/nginx/error.log
  tags: ["error"]

output.kafka:
  hosts: ["10.0.0.51:9092", "10.0.0.52:9092", "10.0.0.53:9092"]
  topic: 'filebeat'

setup.template.name: "nginx"
setup.template.pattern: "nginx_*"
setup.template.enabled: false
setup.template.overwrite: true
EOF

15.修改logstash配置文件

cat >/etc/logstash/conf.d/kafka.conf <<EOF
input {
  kafka{
    bootstrap_servers=>["10.0.0.51:9092,10.0.0.52:9092,10.0.0.53:9092"]
    topics=>["filebeat"]
    #group_id=>"logstash"
    codec => "json"
  }
}

filter {
  mutate {
    convert => ["upstream_time", "float"]
    convert => ["request_time", "float"]
  }
}

output {
   stdout {}
   if "access" in [tags] {
      elasticsearch {
        hosts => "http://10.0.0.51:9200"
        manage_template => false
        index => "nginx_access-%{+yyyy.MM}"
      }
    }
    if "error" in [tags] {
      elasticsearch {
        hosts => "http://10.0.0.51:9200"
        manage_template => false
        index => "nginx_error-%{+yyyy.MM}"
      }
    }
}
EOF

16.启动logstash并测试

1.前台启动

/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/kafka.conf

2.后台启动

systemctl start logstash

17.logstash移除不需要的字段

在filter区块里添加remove_field字段即可

filter {
  mutate {
    convert => ["upstream_time", "float"]
    convert => ["request_time", "float"]
    remove_field => [ "beat" ]
  }
}

第19章 如何在公司推广ELK

  • 优先表达对别人的好处,可以让别人早下班
  • 实验环境准备充足,可以随时打开演示,数据和画图丰富一些
  • 开发组,后端组,前端组,运维组,DBA组 单独定制面板
  • 单独找组长,说优先给咱们组解决问题
  • 你看,你有问题还得这么麻烦跑过来,我给你调好之后,你直接点点鼠标就可以了,如果还有问题,您一句话,我过去
