ELKB5.2.2集群环境的部署过程

发布时间:2021-09-10 12:58:34 来源:亿速云 阅读:133 作者:chen 栏目:建站服务器

本篇内容主要讲解“ELKB5.2.2集群环境的部署过程”,感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习“ELKB5.2.2集群环境的部署过程”吧!

ELKB5.2.2集群环境部署

本人陆陆续续接触了ELK的1.4,2.0,2.4,5.0,5.2版本,可以说前面使用当中一直没有太多感触,最近使用5.2才慢慢有了点感觉,可见认知事务的艰难,本次文档尽量详细点,现在写文档越来越喜欢简洁了,不知道是不是不太好。不扯了看正文(注意这里的配置是优化前配置,正常使用没问题,量大时需要优化)。

备注:

本次属于大版本变更,有很多修改,部署重大修改如下:

1,filebeat直接输出kafka,并drop不必要的字段如beat相关的

2,elasticsearch集群布局优化:分三master节点6data节点

3,logstash filter 加入urldecode支持url、reffer、agent中文显示

4,logstash fileter加入geoip支持客户端ip区域城市定位功能

5, logstash mutate替换字符串并remove不必要字段如kafka相关的

5,elasticsearch插件需要另外部署node.js,不能像以前一样集成一起

6,nginx日志新增request参数、请求方法

一,架构

可选架构

filebeat--elasticsearch--kibana

filebeat--logstash--kafka--logstash--elasticsearch--kibana

filebeat--kafka--logstash--elasticsearch--kibana

由于filebeat5.2.2支持多种输出logstash、elasticsearch、kafka、redis、syslog、file等,为了优化资源使用率且能够支持大并发场景选择

filebeat(18)--kafka(3)--logstash(3)--elasticsearch(3)--kibana(3--nginx负载均衡

共3台物理机、12台虚拟机、系统CentOS6.8、具体划分如下:

服务器一(192.168.188.186)
kafka1  32G700G4CPU
logstash8G      100G    4CPU
elasticsearch2  40G1.4T    8CPU
elasticsearch3  40G     1.4T    8CPU
服务器二(192.168.188.187)
kafka2  32G700G4CPU
logstash8G      100G    4CPU
elasticsearch4  40G1.4T    8CPU
elasticsearch5  40G     1.4T    8CPU
服务器三(192.168.188.188)
kafka3  32G700G4CPU
logstash8G      100G    4CPU
elasticsearch6  40G1.4T    8CPU
elasticsearch7  40G     1.4T    8CPU
磁盘分区

SWAP  8G    /boot  200M   /30G  剩下 /data
Elasticsearch 1.4T
SWAP  8G    /boot  200M   /30G  剩下 /data
IP分配
Elasticsearch2-6     192.168.188.191-196
kibana1-3              192.168.188.191/193/195
kafka1-3                192.168.188.237-239
logstash                192.168.188.238/198/240

二,环境准备

yum -y remove java-1.6.0-openjdk
yum -y remove java-1.7.0-openjdk
yum -y remove perl-*
yum -y remove sssd-*
yum -y install  java-1.8.0-openjdk
java -version
yum update
reboot

设置host环境kafka需要用到

cat /etc/hosts

192.168.188.191   ES191(master和data)
192.168.188.192   ES192(data)
192.168.188.193   ES193(master和data)
192.168.188.194   ES194(data)
192.168.188.195   ES195(master和data)
192.168.188.196   ES196(data)
192.168.188.237   kafka237
192.168.188.238   kafka238
192.168.188.239   kafka239
192.168.188.197   logstash297 
192.168.188.198   logstash298
192.168.188.240   logstash340

三,部署elasticsearch集群

mkdir /data/esnginx

mkdir /data/eslog

rpm -ivh /srv/elasticsearch-5.2.2.rpm 

chkconfig --add elasticsearch

chkconfig postfix off

rpm -ivh /srv/kibana-5.2.2-x86_64.rpm 

chown  elasticsearch:elasticsearch /data/eslog -R

chown  elasticsearch:elasticsearch /data/esnginx -R

配置文件(3master+6data)

[root@ES191 elasticsearch]# cat elasticsearch.yml|grep -Ev '^#|^$'

cluster.name: nginxlog
node.name: ES191
node.master: true
node.data: true
node.attr.rack: r1
path.data: /data/esnginx
path.logs: /data/eslog
bootstrap.memory_lock: true
network.host: 192.168.188.191
http.port: 9200
transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["192.168.188.191","192.168.188.192","192.168.188.193","192.168.188.194","192.168.188.195","192.168.188.196"]
discovery.zen.minimum_master_nodes: 2
gateway.recover_after_nodes: 5
gateway.recover_after_time: 5m
gateway.expected_nodes: 6
cluster.routing.allocation.same_shard.host: true 
script.engine.groovy.inline.search: on
script.engine.groovy.inline.aggs: on
indices.recovery.max_bytes_per_sec: 30mb
http.cors.enabled: true
http.cors.allow-origin: "*"
bootstrap.system_call_filter: false#内核3.0以下的需要,centos7内核3.10不需要

特别注意

/etc/security/limits.conf
elasticsearch  soft  memlock  unlimited
elasticsearch  hard  memlock  unlimited
elasticsearch  soft  nofile   65536
elasticsearch  hard  nofile   131072
elasticsearch  soft  nproc    2048
elasticsearch  hard  nproc    4096
/etc/elasticsearch/jvm.options
# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space
-Xms20g
-Xmx20g

启动集群

service elasticsearch start

健康检查

http://192.168.188.191:9200/_cluster/health?pretty=true
{
  "cluster_name" : "nginxlog",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 6,
  "number_of_data_nodes" : 6,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

elasticsearch-head插件

http://192.168.188.215:9100/

连接上面192.168.188.191:9200任意一台即可

设置分片

官方建议生成索引时再设置

curl -XPUT 'http://192.168.188.193:9200/_all/_settings?preserve_existing=true' -d '{

  "index.number_of_replicas" : "1",

  "index.number_of_shards" : "6"

}'

没有生效,后来发现这个分片设置可以在模版创建时指定,目前还是使用默认1副本,5分片。

其他报错(这个只是参考,优化时有方案)

bootstrap.system_call_filter: false   # 针对 system call filters failed to install,

参见 https://www.elastic.co/guide/en/elasticsearch/reference/current/system-call-filter-check.html

[WARN ][o.e.b.JNANatives ] unable to install syscall filter: 

java.lang.UnsupportedOperationException: seccomp unavailable: requires kernel 3.5+ with CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER compiled in

四、部署kafka集群

kafka集群搭建

1,zookeeper集群

wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
tar zxvf zookeeper-3.4.10.tar.gz -C /usr/local/
ln -s /usr/local/zookeeper-3.4.10/ /usr/local/zookeeper
mkdir -p /data/zookeeper/data/
vim /usr/local/zookeeper/conf/zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data/zookeeper/data
clientPort=2181
server.1=192.168.188.237:2888:3888
server.2=192.168.188.238:2888:3888
server.3=192.168.188.239:2888:3888
vim /data/zookeeper/data/myid
1
/usr/local/zookeeper/bin/zkServer.sh start

2,kafka集群

wget http://mirrors.hust.edu.cn/apache/kafka/0.10.0.1/kafka_2.11-0.10.0.1.tgz

tar zxvf kafka_2.11-0.10.0.1.tgz -C /usr/local/

ln -s /usr/local/kafka_2.11-0.10.0.1 /usr/local/kafka

diff了下server.properties和zookeeper.properties变动不大可以直接使用

vim /usr/local/kafka/config/server.properties

broker.id=237
port=9092
host.name=192.168.188.237
num.network.threads=4
 
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/data/kafkalog
num.partitions=3
num.recovery.threads.per.data.dir=1
log.retention.hours=24
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
log.cleaner.enable=false
zookeeper.connect=192.168.188.237:2181,192.168.188.238:2181,192.168.188.239:237
zookeeper.connection.timeout.ms=6000
producer.type=async
broker.list=192.168.188.237:9092,192.168.188.238:9092,192.168.188.239:9092

mkdir /data/kafkalog

修改内存使用大小

vim /usr/local/kafka/bin/kafka-server-start.sh

    export KAFKA_HEAP_OPTS="-Xmx16G -Xms16G"

启动kafka

/usr/local/kafka/bin/kafka-server-start.sh -daemon /usr/local/kafka/config/server.properties

创建六组前端topic

/usr/local/kafka/bin/kafka-topics.sh --create --topic ngx1-168 --replication-factor 1 --partitions 3 --zookeeper 192.168.188.237:2181,192.168.188.238:2181,192.168.188.239:2181

/usr/local/kafka/bin/kafka-topics.sh --create --topic ngx2-178 --replication-factor 1 --partitions 3 --zookeeper  192.168.188.237:2181,192.168.188.238:2181,192.168.188.239:2181

/usr/local/kafka/bin/kafka-topics.sh --create --topic ngx3-188 --replication-factor 1 --partitions 3 --zookeeper  192.168.188.237:2181,192.168.188.238:2181,192.168.188.239:2181

检查topic

/usr/local/kafka/bin/kafka-topics.sh --list --zookeeper  192.168.188.237:2181,192.168.188.238:2181,192.168.188.239:2181

ngx1-168

ngx2-178

ngx3-188

3,开机启动

cat /etc/rc.local

/usr/local/zookeeper/bin/zkServer.sh start

/usr/local/kafka/bin/kafka-server-start.sh  -daemon /usr/local/kafka/config/server.properties 

注意:开机启动如果设置在rc.local里,java安装又不是用yum安装的openjdk-1.8.0时,需要指定JAVA_HOME,否则java环境不生效,受java环境影响的zookeeper与kafka服务也启动不了,因为java环境一般配置在/etc/profile里,它的生效时间在rc.local后。 

五,部署配置logstash

安装

rpm -ivh logstash-5.2.2.rpm

mkdir /usr/share/logstash/config

#1. 复制配置文件到logstash home

cp /etc/logstash /usr/share/logstash/config

#2. 配置路径

vim /usr/share/logstash/config/logstash.yml

修改前:

path.config: /etc/logstash/conf.d

修改后:

path.config: /usr/share/logstash/config/conf.d

#3.修改 startup.options

修改前:

LS_SETTINGS_DIR=/etc/logstash

修改后:

LS_SETTINGS_DIR=/usr/share/logstash/config

修改startup.options需要执行/usr/share/logstash/bin/system-install 生效

配置

消费者输出端3个logstash只负责一部分

in-kafka-ngx1-out-es.conf

in-kafka-ngx2-out-es.conf

in-kafka-ngx3-out-es.conf

[root@logstash297 conf.d]# cat in-kafka-ngx1-out-es.conf

  }
}

nginx 模版

[root@logstash297 logstash]# cat /usr/share/logstash/templates/nginx_template

               "fields" : {
                 "raw" : {"type": "string", "index" : "not_analyzed", "ignore_above" : 512}
               }
           }
         }
       } ],
       "properties": {
         "@version": { "type": "string", "index": "not_analyzed" },
         "geoip"  : {
           "type": "object",
             "dynamic": true,
             "properties": {
               "location": { "type": "geo_point" }
             }
         }
       }
    }
  }
}

启动

/usr/share/logstash/bin/logstash -f /usr/share/logstash/config/conf.d/in-kafka-ngx1-out-es.conf  &

默认logstash开机启动

六,部署配置filebeat

安装

rpm -ivh filebeat-5.2.2-x86_64.rpm

nginx日志格式需要为json的

  log_format access '{ "@timestamp": "$time_iso8601", '
                         '"clientRealIp": "$clientRealIp", '
                         '"size": $body_bytes_sent, '
                         '"request": "$request", '
                         '"method": "$request_method", '
                         '"responsetime": $request_time, '
                         '"upstreamhost": "$upstream_addr", '
                         '"http_host": "$host", '
                         '"url": "$uri", '
                         '"referrer": "$http_referer", '
                         '"agent": "$http_user_agent", '
                         '"status": "$status"} ';

配置filebeat

vim /etc/filebeat/filebeat.yml

filebeat.prospectors:
- input_type: log
  paths:
    - /data/wwwlogs/*.log
  document_type: ngx1-168
  tail_files: true
  json.keys_under_root: true
  json.add_error_key: true
output.kafka:
  enabled: true
  hosts: ["192.168.188.237:9092","192.168.188.238:9092","192.168.188.239:9092"]
  topic: '%{[type]}'
  partition.round_robin:
    reachable_only: false
  required_acks: 1
  compression: gzip
  max_message_bytes: 1000000
  worker: 3
processors:
- drop_fields:
    fields: ["input_type", "beat.hostname", "beat.name", "beat.version", "offset", "source"] 
logging.to_files: true
logging.files:
  path: /var/log/filebeat
  name: filebeat
  rotateeverybytes: 10485760 # = 10MB
  keepfiles: 7

filebeat详细配置参考官网

https://www.elastic.co/guide/en/beats/filebeat/5.2/index.html

采用kafka作为日志输出端

https://www.elastic.co/guide/en/beats/filebeat/5.2/kafka-output.html

output.kafka:

  # initial brokers for reading cluster metadata

  hosts: ["kafka1:9092", "kafka2:9092", "kafka3:9092"]

  # message topic selection + partitioning

  topic: '%{[type]}'

  partition.round_robin:

    reachable_only: false

  required_acks: 1

  compression: gzip

  max_message_bytes: 1000000

启动

chkconfig filebeat on

/etc/init.d/filebeat start

报错处理

[root@localhost ~]# tail -f /var/log/filebeat/filebeat

2017-05-09T15:21:39+08:00 ERR Error decoding JSON: invalid character 'x' in string escape code

使用$uri 可以在nginx对URL进行更改或重写,但是用于日志输出可以使用$request_uri代替,如无特殊业务需求,完全可以替换

参考

http://www.mamicode.com/info-detail-1368765.html

七,验证

1,kafka消费者查看

/usr/local/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic ngx1-168 

2,elasticserch head查看Index及分片信息

八,部署配置kibana

1,配置启动

cat /etc/kibana/kibana.yml

server.port: 5601

server.host: "192.168.188.191"

elasticsearch.url: "http://192.168.188.191:9200"

chkconfig --add kibana

/etc/init.d/kibana start

2,字段格式

{
  "_index": "filebeat-ngx1-168-2017.05.10",
  "_type": "ngx1-168",
  "_id": "AVvvtIJVy6ssC9hG9dKY",

      1494404040000
    ]
  },
  "sort": [
    1494404040000
  ]
}

3,视图仪表盘

1),添加高德地图

编辑kibana配置文件kibana.yml,最后面添加

tilemap.url: 'http://webrd02.is.autonavi.com/appmaptile?lang=zh_cn&size=1&scale=1&style=7&x={x}&y={y}&z={z}'

ES 模版的调整,Geo-points 不适用 dynamic mapping 因此这类项目需要显式的指定:

需要将 geoip.location 指定为 geo_point 类型,则在模版的 properties 中增加一个项目,如下所示:

       "properties": {

         "@version": { "type": "string", "index": "not_analyzed" },

         "geoip"  : {

           "type": "object",

             "dynamic": true,

             "properties": {

               "location": { "type": "geo_point" }

             }

         }

       }

4,安装x-pack插件

参考

https://www.elastic.co/guide/en/x-pack/5.2/installing-xpack.html#xpack-installing-offline

https://www.elastic.co/guide/en/x-pack/5.2/setting-up-authentication.html#built-in-users

注意要修改密码

http://192.168.188.215:5601/app/kibana#/dev_tools/console?load_from=https://www.elastic.co/guide/en/x-pack/5.2/snippets/setting-up-authentication/1.json

http://192.168.188.215:5601/app/kibana#/dev_tools/console?load_from=https://www.elastic.co/guide/en/x-pack/5.2/snippets/setting-up-authentication/2.json

http://192.168.188.215:5601/app/kibana#/dev_tools/console?load_from=https://www.elastic.co/guide/en/x-pack/5.2/snippets/setting-up-authentication/3.json

或者

curl -XPUT 'localhost:9200/_xpack/security/user/elastic/_password?pretty' -H 'Content-Type: application/json' -d'

{

  "password": "elasticpassword"

}

'

curl -XPUT 'localhost:9200/_xpack/security/user/kibana/_password?pretty' -H 'Content-Type: application/json' -d'

{

  "password": "kibanapassword"

}

'

curl -XPUT 'localhost:9200/_xpack/security/user/logstash_system/_password?pretty' -H 'Content-Type: application/json' -d'

{

  "password": "logstashpassword"

}

'

下面是官网x-pack安装升级卸载文档,后发现注册版本的x-pack,只具有监控功能,就没安装

Installing X-Pack on Offline Machines
The plugin install scripts require direct Internet access to download and install X-Pack. If your server doesn’t have Internet access, you can manually download and install X-Pack.
To install X-Pack on a machine that doesn’t have Internet access:
Manually download the X-Pack zip file: https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-5.2.2.zip (sha1)
Transfer the zip file to a temporary directory on the offline machine. (Do NOT put the file in the Elasticsearch plugins directory.)
Run bin/elasticsearch-plugin install from the Elasticsearch install directory and specify the location of the X-Pack zip file. For example:
bin/elasticsearch-plugin install file:///path/to/file/x-pack-5.2.2.zip
Note
You must specify an absolute path to the zip file after the file:// protocol.
Run bin/kibana-plugin install from the Kibana install directory and specify the location of the X-Pack zip file. (The plugins for Elasticsearch, Kibana, and Logstash are included in the same zip file.) For example:
bin/kibana-plugin install file:///path/to/file/x-pack-5.2.2.zip
Run bin/logstash-plugin install from the Logstash install directory and specify the location of the X-Pack zip file. (The plugins for Elasticsearch, Kibana, and Logstash are included in the same zip file.) For example:
bin/logstash-plugin install file:///path/to/file/x-pack-5.2.2.zip
Enabling and Disabling X-Pack Features
By default, all X-Pack features are enabled. You can explicitly enable or disable X-Pack features in elasticsearch.yml and kibana.yml:
SettingDescription
xpack.security.enabled
Set to false to disable X-Pack security. Configure in both elasticsearch.yml and kibana.yml.
xpack.monitoring.enabled
Set to false to disable X-Pack monitoring. Configure in both elasticsearch.yml and kibana.yml.

xpack.reporting.enabled
Set to false to disable X-Pack reporting. Configure in kibana.yml only.

九、Nginx负载均衡

1,配置负载

[root@~# cat /usr/local/nginx/conf/nginx.conf 

server

{
    listen   5601;
    server_name 192.168.188.215;
    index index.html index.htm index.shtml;
    location / {
        allow  192.168.188.0/24;
        deny all;
        proxy_pass http://kibanangx_niubi_com;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;       
       auth_basic "Please input Username and Password";
       auth_basic_user_file /usr/local/nginx/conf/.pass_file_elk;
    }
          access_log  /data/wwwlogs/access_kibanangx.niubi.com.log  access;
}
upstream kibanangx_niubi_com {
        ip_hash;
        server  192.168.188.191:5601;
        server  192.168.188.193:5601;
        server  192.168.188.195:5601;
}

2,访问

-------------------------------------------------------------------------------------------------

完美的分割线

-------------------------------------------------------------------------------------------------

优化文档

ELKB5.2集群优化方案

一,优化效果

优化前 

收集日志请求达到1万/s,延时10s内,默认设置数据10s刷新。

优化后

收集日志请求达到3万/s,延时10s内,默认设置数据10s刷新。(预估可以满足最大请求5万/s)

缺点:CPU处理能力不足,在dashboard大时间聚合运算是生成仪表视图会有超时现象发生;另外elasticsarch结构和搜索语法等还有进一步优化空间。

二,优化步骤

1,内存和CPU重新规划

1),es                       16CPU  48G内存

2),kafka                 8CPU   16G内存

3),logstash            16CPU  12G内存

2,kafka优化

kafka manager 监控观察消费情况

kafka heap size需要修改

logstash涉及kafka的一个参数修改

1),修改jvm内存数

vi /usr/local/kafka/bin/kafka-server-start.sh

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then

    export KAFKA_HEAP_OPTS="-Xmx8G -Xms8G"

    export JMX_PORT="8999"

fi

2),Broker参数配置

配置优化都是修改server.properties文件中参数值

网络和io操作线程配置优化

# broker处理消息的最大线程数(默认3,可以为CPU核数) 

num.network.threads=4   

# broker处理磁盘IO的线程数 (默认4,可以为CPU核数2倍左右)

num.io.threads=8     

3),安装kafka监控

/data/scripts/kafka-manager-1.3.3.4/bin/kafka-manager

http://192.168.188.215:8099/clusters/ngxlog/consumers

3,logstah优化

logstas需要修改2个配置文件

1),修改jvm参数

vi /usr/share/logstash/config/jvm.options 

-Xms2g

-Xmx6g

2),修改logstash.yml

vi /usr/share/logstash/config/logstash.yml

path.data: /var/lib/logstash

pipeline.workers: 16#cpu核心数

pipeline.output.workers: 4#这里相当于output elasticsearch里面的workers数

pipeline.batch.size: 5000#根据qps,压力情况等填写

pipeline.batch.delay: 5

path.config: /usr/share/logstash/config/conf.d

path.logs: /var/log/logstash

3),修改对应的logstash.conf文件

input文件

vi /usr/share/logstash/config/in-kafka-ngx12-out-es.conf 

input {
  kafka {
  bootstrap_servers => "192.168.188.237:9092,192.168.188.238:9092,192.168.188.239:9092"
  group_id => "ngx1"
  topics => ["ngx1-168"]
  codec => "json"
  consumer_threads => 3
  auto_offset_reset => "latest"   #添加这行
  #decorate_events =>   #true 这行去掉
  }
}

filter文件

filter {
  mutate {
    gsub => ["message", "\\x", "%"]   #这个是转义,url里面的加密方式和request等不一样,用于汉字显示
    #remove_field => ["kafka"]这行去掉  decorate events 默认false后就不添加kafka.{}字段了,这里也及不需要再remove了
  }

output文件

修改前

    flush_size => 50000

    idle_flush_time => 10

修改后

4秒集齐8万条一次性输出

    flush_size => 80000

    idle_flush_time => 4

启动后logstash输出(pipeline.max_inflight是8万)

[2017-05-16T10:07:02,552][INFO ][logstash.pipeline        ] Starting pipeline {"id"=>"main", "pipeline.workers"=>16, "pipeline.batch.size"=>5000, "pipeline.batch.delay"=>5, "pipeline.max_inflight"=>80000}
[2017-05-16T10:07:02,553][WARN ][logstash.pipeline        ] CAUTION: Recommended inflight events max exceeded! Logstash will run with up to 80000 events in memory in your current configuration. If your message sizes are large this may cause instability with the default heap size. Please consider setting a non-standard heap size, changing the batch size (currently 5000), or changing the number of pipeline workers (currently 16)

4,elasticsearch优化

1),修改jvm参加

vi /etc/elasticsearch/jvm.options

调整为24g,最大为虚拟机内存的50%

-Xms24g

-Xmx24g

2),修改GC方法(待定,后续观察,该参数不确定时不建议修改)

elasticsearch默认使用的GC是CMS GC

如果你的内存大小超过6G,CMS是不给力的,容易出现stop-the-world

建议使用G1 GC

注释掉:

JAVA_OPTS=”$JAVA_OPTS -XX:+UseParNewGC”

JAVA_OPTS=”$JAVA_OPTS -XX:+UseConcMarkSweepGC”

JAVA_OPTS=”$JAVA_OPTS -XX:CMSInitiatingOccupancyFraction=75″

JAVA_OPTS=”$JAVA_OPTS -XX:+UseCMSInitiatingOccupancyOnly”

修改为:

JAVA_OPTS=”$JAVA_OPTS -XX:+UseG1GC”

JAVA_OPTS=”$JAVA_OPTS -XX:MaxGCPauseMillis=200″

3),安装elasticsearch集群监控工具Cerebro

https://github.com/lmenezes/cerebro

Cerebro 时一个第三方的 elasticsearch 集群管理软件,可以方便地查看集群状态:

https://github.com/lmenezes/cerebro/releases/download/v0.6.5/cerebro-0.6.5.tgz

安装后访问地址

http://192.168.188.215:9000/

4),elasticsearch搜索参数优化(难点问题)

发现没事可做的,首先默认配置已经很好了,其次bulk,刷新等配置里都写好了 

5),elasticsarch集群角色优化

es191,es193,es195只做master节点+ingest节点

es192,es194,es196只做data节点(上面是虚拟机2个虚拟机共用一组raid5磁盘,如果都做data节点性能表现不好)

再加2个data节点,这样聚合计算性能提升很大

5,filebeat优化

1),使用json格式输入,这样logstash就不需要dcode减轻后端压力

  json.keys_under_root: true

  json.add_error_key: true

2),drop不必要的字段如下

vim /etc/filebeat/filebeat.yml 

processors:

- drop_fields:

    fields: ["input_type", "beat.hostname", "beat.name", "beat.version", "offset", "source"]

3),计划任务删索引

index默认保留5天

cat /data/scripts/delindex.sh 

#!/bin/bash
OLDDATE=`date -d  -5days  +%Y.%m.%d`
echo  $OLDDATE
curl -XDELETE http://192.168.188.193:9200/filebeat-ngx1-168-$OLDDATE
curl -XDELETE http://192.168.188.193:9200/filebeat-ngx2-178-$OLDDATE
curl -XDELETE http://192.168.188.193:9200/filebeat-ngx3-188-$OLDDATE
