filebeat+elk日志收集平台搭建流程
1、 整体简介：
模式：单机
平台：Linux - centos - 7
ELK：elasticsearch、logstash、kibana三款开源软件的集合。
FILEBEAT：代替logstash的采集功能，轻量、耗用小。
目前收集的有nginx日志、java日志[单行|多行]。
都是通过在客户端的生成日志配置文件中定义好初步json格式，然后利用filebeat采集到logstash，存储到elasticsearch，最后通过kibana在浏览器页面中展示出来。
elasticsearch、logstash、kibana 如果是root安装，默认会创建（elasticsearch、logstash、kibana）三个单独用户来独立运行。用www用户安装好后默认是以www用户运行。本文演示用的是www。
2、 软件环境安装：
（1）、java环境：
Elasticsearch需要安装Java 8的环境。
如果没有下载jdk1.8的软件包，可以直接安装 java-1.8.0-openjdk。
（2）、下载elasticsearch（Linux版本）的二进制包并解压：
$ wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.0.tar.gz
$ unzip elasticsearch-6.4.0.tar.gz
$ mv elasticsearch-6.4.0 elasticsearch
$ vim elasticsearch/config/elasticsearch.yml
|
path.data: /data/soft/elasticsearch/data/ path.logs: /data/soft/elasticsearch/logs/ |
$ sudo sysctl -w vm.max_map_count=262144
$ vim /etc/sysctl.conf文件，添加：
|
vm.max_map_count=262144 |
$ sysctl -p
$ vim /etc/security/limits.conf文件，末尾添加:
|
* soft nproc 20536 * hard nproc 20536 * soft nofile 65536 * hard nofile 65536 |
退出重新登录生效。
将elasticsearch、logstash、kibana、filebeat的bin目录加入到环境变量PATH：
/data/soft/logstash/bin:/data/soft/kibana/bin:/data
/soft/elasticsearch/bin:/data/soft/filebeat
$ nohup elasticsearch -d >/data/soft/elasticsearch/nohup.out
2>&1 &
启动后，Elastic默认在9200端口运行。
$ curl -X GET localhost:9200或curl localhost:9200

（3）、下载logstash（Linux版本）的二进制包并解压：
$ wget https://artifacts.elastic.co/downloads/logstash/logstash-6.4.0.zip
$ unzip logstash-6.4.0.zip logstash-6.4.0
$ mv logstash-6.4.0 logstash
$ cd logstash/config/
$ cat config/logstash.yml|grep -vE '^$|#'

检查logstash配置文件的语法命令：
$ logstash --path.settings /data/soft/logstash/config/ -f /data/soft/logstash/config/logstash.conf -t
$ nohup logstash -f /data/soft/logstash/config/logstash.conf >/data/soft/logstash/out.log 2>&1 &
（4）、下载kibana（Linux版本）的二进制包并解压：
$ wget https://artifacts.elastic.co/downloads/kibana/kibana-6.4.0-linux-x86_64.tar.gz
$ tar -zxf kibana-6.4.0-linux-x86_64.tar.gz
$ mv kibana-6.4.0-linux-x86_64 kibana
$ vim kibana/config/kibana.yml
|
elasticsearch.url: "http://localhost:9200" elasticsearch.shardTimeout: 0 pid.file: /data/soft/kibana/kibana.pid |
$ nohup /data/soft/kibana/bin/kibana >/data/soft/kibana/out.log 2>&1 &
3、 FILEBEAT（收集端）单独配置：
以一台filebeat采集端做示例：
（1）、nginx日志格式配置：
$ vim /data/soft/nginx/conf/nginx.conf
|
user www; |
|
worker_processes 4; |
|
worker_rlimit_nofile 20000; |
|
worker_cpu_affinity 00000001 00000010 00000100 00001000; |
|
error_log /log/nginx/error.log error; |
|
pid /log/nginx/nginx.pid; |
|
events { |
|
use epoll; |
|
worker_connections 20000; |
|
} |
|
http { |
|
include mime.types; |
|
default_type application/octet-stream; |
|
sendfile on; |
|
tcp_nodelay on; |
|
tcp_nopush on; |
|
client_body_timeout 10; |
|
client_header_timeout 10; |
|
send_timeout 10; |
|
keepalive_timeout 50; |
|
client_body_buffer_size 4k; |
|
client_header_buffer_size 1k; |
|
client_max_body_size 10m; |
|
large_client_header_buffers 2 1k; |
|
open_file_cache max=65535 inactive=20s; |
|
open_file_cache_valid 30s; |
|
open_file_cache_min_uses 1; |
|
gzip on; |
|
gzip_min_length 1k; |
|
gzip_buffers 8 16k; |
|
gzip_comp_level 3; |
|
gzip_http_version 1.1; |
|
gzip_disable "MSIE [1-6]."; |
|
gzip_types text/plain application/x-javascript text/css application/xml application/x-httpd-php image/jpeg image/gif image/png; |
|
gzip_vary on; # nginx需要配置的日志输出格式为json格式：代替logstash的grok过滤。 |
|
log_format main '{"nx_localtime@timestamp":"$time_local",' |
|
'"nx_host":"$server_addr",' |
|
'"nx_client_ip":"$remote_addr",' |
|
'"nx_body_size":$body_bytes_sent,' |
|
'"nx_request_time":$request_time,' |
|
'"nx_scheme":"$scheme",' |
|
'"nx_http_host":"$host",' |
|
'"nx_request_method":"$request_method",' |
|
'"nx_uri":"$uri",' |
|
'"nx_status":"$status",' |
|
'"nx_referer":"$http_referer",' |
|
'"nx_agent":"$http_user_agent",' |
|
'"nx_upstream_host":"$upstream_addr",' |
|
'"nx_upstream_response_time":"$upstream_response_time",' |
|
'"nx_upstream_response_length":"$upstream_response_length",' |
|
'"nx_upstream_status":"$upstream_status",' |
|
'"nx_upstream_connect_time":"$upstream_connect_time"}'; |
|
include vhost/*.conf; |
|
} |
访问nginx，查看此时nginx-log中的输出：
|
{"nx_localtime@timestamp":"27/Sep/2018:21:37:17 +0800","nx_host":"156.237.192.218","nx_client_ip":"113.61.62.154","nx_body_size":665,"nx_request_time":0.000,"nx_scheme":"http","nx_http_host":"log.2481888.com","nx_request_method":"GET","nx_uri":"/nginx/","nx_status":"200","nx_referer":"http://log.2481888.com/","nx_agent":"Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36","nx_upstream_host":"","nx_upstream_response_time":"","nx_upstream_response_length":"","nx_upstream_status":"","nx_upstream_connect_time":""} |
（2）、java日志格式配置：
利用spring cloud config配置中心的集中化管理java日志输出，修改统一的配置文件：
$ vim /data/www/java/log4j2.xml
|
<configuration status="INFO"> |
|
<!-- 参数配置 --> |
|
<properties> |
|
<property name="app_name">${sys:project.name}</property> |
|
<property name="log_path">/log/${app_name}</property> |
|
<!-- 文件输出格式配成json格式，方便filebeat收集，省略logsta过滤 --> |
|
<property name="PATTERN">{"jv_time":"%d{yyyy-MM-dd HH:mm:ss.SSS}","jv_level":"%level","jv_thread":"%thread","jv_class":"%logger","jv_method":"%M","jv_message":"%replace{%replace{%msg}{"}{\"}}{ }{|}","jv_throwable":"%replace{%replace{%xEx}{"}{\"}}{[ ]}{|}"}%n{%xEx}{none}</property> |
|
</properties> |
|
<appenders> ... ... |
重启java项目后，此时日志中的输出就变成json格式了。
|
{"jv_time": "2018 09 29 20:16:32.672","jv_level": "INFO","jv_thread": "MQClientFactoryScheduledThread", "jv_class": "RocketmqClient", "jv_method": "sendHeartbeatToAllBroker","jv_message": "send heart beat to broker[broker-a 0 8bet-test-srv-2:10911] success","jv_throwable": ""} |
（3）、filebeat的安装与配置：
$wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.4.0-linux-x86_64.tar.gz
$ tar -zxf filebeat-6.4.0-linux-x86_64.tar.gz
$ mv filebeat-6.4.0-linux-x86_64 filebeat
$ vim filebeat/filebeat.yml

启动：
$ /data/soft/filebeat/filebeat -c /data/soft/filebeat/filebeat.yml &
PS：最后将elk和filebeat的相关命令写入到启动脚本简化操作。
4、 REST API方式操作：
常用的几种操作示例：
$ curl -XGET 'localhost:9200/_cat/health?v&pretty=true'
$ curl -XPUT 'localhost:9200/laptops'
$curl -XPUT 'localhost:9200/laptops/doc/1?pretty&pretty' -H 'Content-Type: application/json' -d ‘{ "title": "Laptop X1 i7 8gb RAM " }’
$curl -XPUT 'localhost:9200/laptops/doc/2?pretty&pretty' -H 'Content-Type: application/json' -d ‘{ "title": "Laptop X2 i5 4gb RAM " }’
$ curl -XGET 'localhost:9200/laptops/_search?pretty=true' -H 'Content-Type: application/json'
$ curl -XDELETE 'localhost:9200/laptops/?pretty=true'

6、 以下部分为摘录网上文档部分【提供参考】：
默认情况下，Elastic 只允许本机访问，如果需要远程访问，可以修改 Elastic 安装目录的config/elasticsearch.yml文件，去掉network.host的注释，将它的值改成0.0.0.0，然后重新启动 Elastic。
network.host:0.0.0.0
上面代码中，设成0.0.0.0让任何人都可以访问。线上服务不要这样设置，要设成具体的 IP。
二、基本概念
2.1 Node 与 Cluster
Elastic 本质上是一个分布式数据库，允许多台服务器协同工作，每台服务器可以运行多个 Elastic 实例。
单个 Elastic 实例称为一个节点（node）。一组节点构成一个集群（cluster）。
2.2 Index
Elastic 会索引所有字段，经过处理后写入一个反向索引（Inverted Index）。查找数据的时候，直接查找该索引。
所以，Elastic 数据管理的顶层单位就叫做 Index（索引）。它是单个数据库的同义词。每个 Index （即数据库）的名字必须是小写。
下面的命令可以查看当前节点的所有 Index。
$ curl-X GET'http://localhost:9200/_cat/indices?v'
2.3 Document
Index 里面单条的记录称为 Document（文档）。许多条 Document 构成了一个 Index。
Document 使用 JSON 格式表示，下面是一个例子。
{
"user":"张三",
"title":"工程师",
"desc":"数据库管理"
}
同一个 Index 里面的 Document，不要求有相同的结构（scheme），但是最好保持相同，这样有利于提高搜索效率。
2.4 Type
Document 可以分组，比如weather这个 Index 里面，可以按城市分组（北京和上海），也可以按气候分组（晴天和雨天）。这种分组就叫做 Type，它是虚拟的逻辑分组，用来过滤 Document。
不同的 Type 应该有相似的结构（schema），举例来说，id字段不能在这个组是字符串，在另一个组是数值。这是与关系型数据库的表的一个区别。性质完全不同的数据（比如products和logs）应该存成两个 Index，而不是一个 Index 里面的两个 Type（虽然可以做到）。
下面的命令可以列出每个 Index 所包含的 Type。
$ curl'localhost:9200/_mapping?pretty=true'
根据规划，Elastic 6.x 版只允许每个 Index 包含一个 Type，7.x 版将会彻底移除 Type。
三、新建和删除 Index
新建 Index，可以直接向 Elastic 服务器发出 PUT 请求。下面的例子是新建一个名叫weather的 Index。
$ curl-X PUT'localhost:9200/weather'
服务器返回一个 JSON 对象，里面的acknowledged字段表示操作成功。
{
"acknowledged":true,
"shards_acknowledged":true
}
然后，我们发出 DELETE 请求，删除这个 Index。
$ curl-X DELETE'localhost:9200/weather'
四、中文分词设置
首先，安装中文分词插件。这里使用的是 ik，也可以考虑其他插件（比如 smartcn）。
$./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.5.1/elasticsearch-analysis-ik-5.5.1.zip
上面代码安装的是5.5.1版的插件，与 Elastic 5.5.1 配合使用。
接着，重新启动 Elastic，就会自动加载这个新安装的插件。
然后，新建一个 Index，指定需要分词的字段。这一步根据数据结构而异，下面的命令只针对本文。基本上，凡是需要搜索的中文字段，都要单独设置一下。
$ curl-X PUT'localhost:9200/accounts'-d'
{
"mappings": {
"person": {
"properties": {
"user": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word"
},
"title": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word"
},
"desc": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word"
}
}
}
}
}'
上面代码中，首先新建一个名称为accounts的 Index，里面有一个名称为person的 Type。person有三个字段。
- § user
- § title
- § desc
这三个字段都是中文，而且类型都是文本（text），所以需要指定中文分词器，不能使用默认的英文分词器。
Elastic 的分词器称为 analyzer。我们对每个字段指定分词器。
"user":{
"type":"text",
"analyzer":"ik_max_word",
"search_analyzer":"ik_max_word"
}
上面代码中，analyzer是字段文本的分词器，search_analyzer是搜索词的分词器。ik_max_word分词器是插件ik提供的，可以对文本进行最大数量的分词。
五、数据操作
5.1 新增记录
向指定的 /Index/Type 发送 PUT 请求，就可以在 Index 里面新增一条记录。比如，向/accounts/person发送请求，就可以新增一条人员记录。
$ curl-X PUT'localhost:9200/accounts/person/1'-d'
{
"user": "张三",
"title": "工程师",
"desc": "数据库管理"
}'
服务器返回的 JSON 对象，会给出 Index、Type、Id、Version 等信息。
{
"_index":"accounts",
"_type":"person",
"_id":"1",
"_version":1,
"result":"created",
"_shards":{"total":2,"successful":1,"failed":0},
"created":true
}
如果你仔细看，会发现请求路径是/accounts/person/1，最后的1是该条记录的 Id。它不一定是数字，任意字符串（比如abc）都可以。
新增记录的时候，也可以不指定 Id，这时要改成 POST 请求。
$ curl-X POST'localhost:9200/accounts/person'-d'
{
"user": "李四",
"title": "工程师",
"desc": "系统管理"
}'
上面代码中，向/accounts/person发出一个 POST 请求，添加一个记录。这时，服务器返回的 JSON 对象里面，_id字段就是一个随机字符串。
{
"_index":"accounts",
"_type":"person",
"_id":"AV3qGfrC6jMbsbXb6k1p",
"_version":1,
"result":"created",
"_shards":{"total":2,"successful":1,"failed":0},
"created":true
}
注意，如果没有先创建 Index（这个例子是accounts），直接执行上面的命令，Elastic 也不会报错，而是直接生成指定的 Index。所以，打字的时候要小心，不要写错 Index 的名称。
5.2 查看记录
向/Index/Type/Id发出 GET 请求，就可以查看这条记录。
$ curl'localhost:9200/accounts/person/1?pretty=true'
上面代码请求查看/accounts/person/1这条记录，URL 的参数pretty=true表示以易读的格式返回。
返回的数据中，found字段表示查询成功，_source字段返回原始记录。
{
"_index":"accounts",
"_type":"person",
"_id":"1",
"_version":1,
"found":true,
"_source":{
"user":"张三",
"title":"工程师",
"desc":"数据库管理"
}
}
如果 Id 不正确，就查不到数据，found字段就是false。
$ curl'localhost:9200/weather/beijing/abc?pretty=true'
{
"_index":"accounts",
"_type":"person",
"_id":"abc",
"found":false
}
5.3 删除记录
删除记录就是发出 DELETE 请求。
$ curl-X DELETE'localhost:9200/accounts/person/1'
这里先不要删除这条记录，后面还要用到。
5.4 更新记录
更新记录就是使用 PUT 请求，重新发送一次数据。
$ curl-X PUT'localhost:9200/accounts/person/1'-d'
{
"user" : "张三",
"title" : "工程师",
"desc" : "数据库管理，软件开发"
}'
{
"_index":"accounts",
"_type":"person",
"_id":"1",
"_version":2,
"result":"updated",
"_shards":{"total":2,"successful":1,"failed":0},
"created":false
}
上面代码中，我们将原始数据从"数据库管理"改成"数据库管理，软件开发"。 返回结果里面，有几个字段发生了变化。
"_version":2,
"result":"updated",
"created":false
可以看到，记录的 Id 没变，但是版本（version）从1变成2，操作类型（result）从created变成updated，created字段变成false，因为这次不是新建记录。
六、数据查询
6.1 返回所有记录
使用 GET 方法，直接请求/Index/Type/_search，就会返回所有记录。
$ curl'localhost:9200/accounts/person/_search'
{
"took":2,
"timed_out":false,
"_shards":{"total":5,"successful":5,"failed":0},
"hits":{
"total":2,
"max_score":1.0,
"hits":[
{
"_index":"accounts",
"_type":"person",
"_id":"AV3qGfrC6jMbsbXb6k1p",
"_score":1.0,
"_source":{
"user":"李四",
"title":"工程师",
"desc":"系统管理"
}
},
{
"_index":"accounts",
"_type":"person",
"_id":"1",
"_score":1.0,
"_source":{
"user":"张三",
"title":"工程师",
"desc":"数据库管理，软件开发"
}
}
]
}
}
上面代码中，返回结果的 took字段表示该操作的耗时（单位为毫秒），timed_out字段表示是否超时，hits字段表示命中的记录，里面子字段的含义如下。
- §
total：返回记录数，本例是2条。 - §
max_score：最高的匹配程度，本例是1.0。 - §
hits：返回的记录组成的数组。
返回的记录中，每条记录都有一个_score字段，表示匹配的程序，默认是按照这个字段降序排列。
6.2 全文搜索
Elastic 的查询非常特别，使用自己的查询语法，要求 GET 请求带有数据体。
$ curl'localhost:9200/accounts/person/_search'-d'
{
"query" : { "match" : { "desc" : "软件" }}
}'
上面代码使用 Match查询，指定的匹配条件是desc字段里面包含"软件"这个词。返回结果如下。
{
"took":3,
"timed_out":false,
"_shards":{"total":5,"successful":5,"failed":0},
"hits":{
"total":1,
"max_score":0.28582606,
"hits":[
{
"_index":"accounts",
"_type":"person",
"_id":"1",
"_score":0.28582606,
"_source":{
"user":"张三",
"title":"工程师",
"desc":"数据库管理，软件开发"
}
}
]
}
}
Elastic 默认一次返回10条结果，可以通过size字段改变这个设置。
$ curl'localhost:9200/accounts/person/_search'-d'
{
"query" : { "match" : { "desc" : "管理" }},
"size": 1
}'
上面代码指定，每次只返回一条结果。
还可以通过from字段，指定位移。
$ curl'localhost:9200/accounts/person/_search'-d'
{
"query" : { "match" : { "desc" : "管理" }},
"from": 1,
"size": 1
}'
上面代码指定，从位置1开始（默认是从位置0开始），只返回一条结果。
6.3 逻辑运算
如果有多个搜索关键字， Elastic 认为它们是or关系。
$ curl'localhost:9200/accounts/person/_search'-d'
{
"query" : { "match" : { "desc" : "软件 系统" }}
}'
上面代码搜索的是软件 or 系统。
如果要执行多个关键词的and搜索，必须使用布尔查询。
$ curl'localhost:9200/accounts/person/_search'-d'
{
"query": {
"bool": {
"must": [
{ "match": { "desc": "软件" } },
{ "match": { "desc": "系统" } }
]
}
}
}'
