ELK日志系统的单机多实例部署

科技 08-01 来源： blueic1115

概述：本部署过程适用于单机es集群化，ELK日志从零开始配置与环境测试，系统为centos7 ，es 默认使用9201、9202、9203端口。由于单机只适用于测试环境，所以不建议在生产环境进行部署，生产环境建议es集群分多台主机多实例，相当于需要将以下的几个实例，拆分部署到不同的主机，以保障高可用性。下面是配置的详细过程：

1、系统优化部分

#vim /etc/security/limits.conf

* soft nofile 65536
* hard nofile 65536
* soft nproc 4096
* hard nproc 4096

#echo "vm.max_map_count = 262144" >> /etc/sysctl.conf && sysctl -p

2、环境准备部分

#yum install -y unzip bzip2 wget lrzsz java-1.8.0-openjdk.x86_64

#mkdir -p /usr/{es01,es02,es03} && cd
#mkdir soft && cd soft
#wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.3.1.tar.gz
#wget https://artifacts.elastic.co/downloads/kibana/kibana-6.3.1-linux-x86_64.tar.gz
#wget https://artifacts.elastic.co/downloads/logstash/logstash-6.3.1.tar.gz
#tar -zxvf elasticsearch-6.3.1.tar.gz
#echo /usr/{es01,es02,es03} | xargs -n 1 cp -r -v elasticsearch-6.3.1/*
#mkdir -p /usr/{es01,es02,es03}/{data,log}

//新版本都不允许root进行es启动，增加esuser用户
#useradd esuser

3、es机器单机多实例配置部分

编辑es01实例的配置文件：
#vim /usr/es01/config/elasticsearch.yml

##es01
cluster.name: escls01
node.name: esnode01
path.data: /usr/es01/data
path.logs: /usr/es01/log
network.host: 172.25.63.29
http.port: 9201
transport.tcp.port: 9301
transport.tcp.compress: true
node.max_local_storage_nodes: 3
discovery.zen.ping.unicast.hosts: ["172.25.63.29:9301", "172.25.63.29:9302","172.25.63.29:9303"]
discovery.zen.minimum_master_nodes: 2

http.enabled: true
http.cors.enabled: true
http.cors.allow-origin: "*"

编辑es02实例的配置文件：

#vim /usr/es02/config/elasticsearch.yml

##es02
cluster.name: escls01
node.name: esnode02
path.data: /usr/es02/data
path.logs: /usr/es02/log
network.host: 172.25.63.29
http.port: 9202
transport.tcp.port: 9302
transport.tcp.compress: true
node.max_local_storage_nodes: 3
discovery.zen.ping.unicast.hosts: ["172.25.63.29:9301", "172.25.63.29:9302","172.25.63.29:9303"]
discovery.zen.minimum_master_nodes: 2

http.enabled: true
http.cors.enabled: true
http.cors.allow-origin: "*"

编辑es03实例的配置文件：

#vim /usr/es03/config/elasticsearch.yml

##es03
cluster.name: escls01
node.name: esnode03
path.data: /usr/es03/data
path.logs: /usr/es03/log
network.host: 172.25.63.29
http.port: 9203
transport.tcp.port: 9303
transport.tcp.compress: true
node.max_local_storage_nodes: 3
discovery.zen.ping.unicast.hosts: ["172.25.63.29:9301", "172.25.63.29:9302","172.25.63.29:9303"]
discovery.zen.minimum_master_nodes: 2

http.enabled: true
http.cors.enabled: true
http.cors.allow-origin: "*"

4、调试部分

依次启动3个实例：
#su esuser
$cd /usr/es01/bin
$./elasticsearch -d

$cd /usr/es02/bin
$./elasticsearch -d

$cd /usr/es03/bin
$./elasticsearch -d

//查看日志情况
$tail -f ../../es01/log/escls01.log

启动第一个实例日志一直是这样的：

[2021-06-10T11:51:24,633][WARN ][o.e.d.z.ZenDiscovery ] [esnode01] not enough master nodes discovered during pinging (found [[Candidate{node={esnode01}{uY-Tq78pSJG1T42LwUrdjg}{n7ViuIuDSpWCpONs6QFHZg}{172.25.63.29}{172.25.63.29:9301}{ml.machine_memory=16656572416, xpack.installed=true, ml.max_open_jobs=20, ml.enabled=true}, clusterStateVersion=-1}]], but needed [2]), pinging again

启动第二个实例后，再看第一个实例日志：

[2021-06-10T11:51:30,436][INFO ][o.e.c.s.ClusterApplierService] [esnode01] detected_master {esnode02}{RMxZm77GT4anPx2NgmALhg}{_rshXRISS72qxr9uiJ_S1w}{172.25.63.29}{172.25.63.29:9302}{ml.machine_memory=16656572416, ml.max_open_jobs=20, xpack.installed=true, ml.enabled=true}, added {{esnode02}{RMxZm77GT4anPx2NgmALhg}{_rshXRISS72qxr9uiJ_S1w}{172.25.63.29}{172.25.63.29:9302}{ml.machine_memory=16656572416, ml.max_open_jobs=20, xpack.installed=true, ml.enabled=true},}, reason: apply cluster state (from master [master {esnode02}{RMxZm77GT4anPx2NgmALhg}{_rshXRISS72qxr9uiJ_S1w}{172.25.63.29}{172.25.63.29:9302}{ml.machine_memory=16656572416, ml.max_open_jobs=20, xpack.installed=true, ml.enabled=true} committed version [1]])

[2021-06-10T11:51:31,029][INFO ][o.e.x.m.e.l.LocalExporter] waiting for elected master node [{esnode02}{RMxZm77GT4anPx2NgmALhg}{_rshXRISS72qxr9uiJ_S1w}{172.25.63.29}{172.25.63.29:9302}{ml.machine_memory=16656572416, ml.max_open_jobs=20, xpack.installed=true, ml.enabled=true}] to setup local exporter [default_local] (does it have x-pack installed?)

启动第三实例个实例后，再看第一个实例日志：

[2021-06-10T11:53:11,954][INFO ][o.e.c.s.ClusterApplierService] [esnode01] added {{esnode03}{xSE5yn-QQZSZSn3Zn0MWvQ}{IDkjpCoASCqkhEMjScx0pw}{172.25.63.29}{172.25.63.29:9303}{ml.machine_memory=16656572416, ml.max_open_jobs=20, xpack.installed=true, ml.enabled=true},}, reason: apply cluster state (from master [master {esnode02}{RMxZm77GT4anPx2NgmALhg}{_rshXRISS72qxr9uiJ_S1w}{172.25.63.29}{172.25.63.29:9302}{ml.machine_memory=16656572416, ml.max_open_jobs=20, xpack.installed=true, ml.enabled=true} committed version [15]])

5、查看实例启动情况

#exit
# netstat -ntpl

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp6 0 0 ::1:25 :::* LISTEN 1002/master

//到此，三个实例都已启动完成

6、简单的http测试

# curl -i "http://172.25.63.29:9201"

HTTP/1.1 200 OK

}

7、安装es网页查看插件elasticsearch-head

#cd && cd soft
#wget https://nodejs.org/dist/v15.8.0/node-v15.8.0-linux-x64.tar.gz
#tar -zxvf node-v15.8.0-linux-x64.tar.gz && mv node-v15.8.0-linux-x64 /usr/nodejs
#cd /usr/bin/ && ln -s /usr/nodejs/bin/node ./node && ln -s /usr/nodejs/bin/npm ./npm
# node -v
v15.8.0
# npm -v
7.5.1

#cd && cd soft
#wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
#wget https://github.com/mobz/elasticsearch-head/archive/refs/heads/master.zip
#unzip master.zip && mv elasticsearch-head-master /usr/elasticsearch-head
#tar -jxfv phantomjs-2.1.1-linux-x86_64.tar.bz2 && mv phantomjs-2.1.1-linux-x86_64 /usr/phantomjs
#cd /usr/bin/ && ln -s /usr/phantomjs/bin/phantomjs ./phantomjs && phantomjs -v
2.1.1
#cd /usr/elasticsearch-head && npm install
#nohup npm run start &

图一

访问：
打开 http://172.25.63.29:9100/，在连接处填写：http://172.25.63.29:9201/ ，点击连接即可。
注：
默认打开 http://172.25.63.29:9100/ ，服务器连接地址处显示：http://localhost:9200/ , 可以修改/usr/elasticsearch-head/_site/app.js , 查找localhost关键字修改即可。

8、网页中创建测试索引，创建几个索引测试一下,如下：

test-index01 5分片，1副本
test-index02 5分片，2副本

图二

日志信息 #tail -f /usr/es01/log/escls01.log ：

==> es01/log/escls01.log <==
[2021-06-10T15:48:10,016][INFO ][o.e.c.m.MetaDataCreateIndexService] [esnode01] [test-index01] creating index, cause [api], templates [], shards [5]/[1], mappings []
[2021-06-10T15:48:10,738][INFO ][o.e.c.r.a.AllocationService] [esnode01] Cluster health status changed from [YELLOW] to [GREEN] (reason: [shards started [[test-index01][1]] ...]).

9、配置kibana部分

#cd && cd soft
#tar -zxvf kibana-6.3.1-linux-x86_64.tar.gz && mv kibana-6.3.1-linux-x86_64 /usr/kibana && cd /usr/kibana
#vim config/kibana.yml

server.host: "0.0.0.0"
elasticsearch.url: "http://172.25.63.29:9201"
xpack.security.encryptionKey: "add_32_characters"
xpack.security.sessionTimeout: 600000
xpack.reporting.enabled: false
xpack.reporting.encryptionKey: "add_32_characters"

//启动kibana
#nohup ./bin/kibana &
访问：http://http://172.25.63.29:5601/

到目前为止，我们启动了8个相关服务端口了，如下：
# netstat -ntpl

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp6 0 0 172.25.63.29:9303 :::* LISTEN 12106/java
tcp6 0 0 ::1:25 :::* LISTEN 1002/master

10、配置logstash部分

#cd && cd soft
#tar -zxvf logstash-6.3.1.tar.gz && mv logstash-6.3.1 /usr/logstash && cd /usr/logstash
//此处我们先增加logstash监控本机三个es节点的日志信息
#vim config/logstash.conf

input {
file {
type => "es01log"
path => "/usr/es01/log/escls01.log"
start_position => "beginning"
}
}

input {
file {
type => "es02log"
path => "/usr/es02/log/escls01.log"
start_position => "beginning"
}
}

input {
file {
type => "es03log"
path => "/usr/es03/log/escls01.log"
start_position => "beginning"
}
}

output {
stdout {
codec => rubydebug { }
}

if[type]=='es01log'{
elasticsearch {
hosts => "172.25.63.29:9201"
index => "es01log-%{+YYYY.MM.dd}"
}
}

if[type]=='es02log'{
elasticsearch {
hosts => "172.25.63.29:9202"
index => "es02log-%{+YYYY.MM.dd}"
}
}

if[type]=='es03log'{
elasticsearch {
hosts => "172.25.63.29:9203"
index => "es03log-%{+YYYY.MM.dd}"
}
}

}

//启动logstash
#nohup ./bin/logstash -f ./config/logstash.conf &

//到目前为止，我们启动了9个相关服务端口了，如下：
# netstat -ntpl

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

11、到此我们测试环境es单机多实例，elk环境的部署就完成了，访问：http://http://172.25.63.29:5601/
