ElasticSearch + Logstash + Kibana 搭建筆記

ElasticSearch 安裝

一、下載 ElasticSearch，本文使用的版本爲 5.5.1。

二、配置

path.data: /data/es #數據路徑 path.logs: /data/logs/es #日誌路徑 network.host: 本機地址 #服務器地址 http.port: 9200 #端口

若是不修改配置的話，默認的數據和日誌都位於elasticsearch文件夾下。

默認地址會使用 192.168.0.1 的地址，此時ElasticSearch運行於開發模式，只能從本機訪問。若是修改成生產地址，就會進入生產模式，而且運行 bootstrap check 。

三、啓動

./bin/elasticsearch

注意，elasticsearch 不能使用 root 用戶啓動，使用其餘用戶啓動，要注意有文件夾的讀寫權限。

我在安裝過程當中還出現了下面幾個警告信息

[2017-08-07T09:13:59,951][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 at org.elasticsearch.bootstrap.SystemCallFilter.linuxImpl(SystemCallFilter.java:350) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.SystemCallFilter.init(SystemCallFilter.java:638) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.JNANatives.tryInstallSystemCallFilter(JNANatives.java:245) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Natives.tryInstallSystemCallFilter(Natives.java:113) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:111) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:194) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:351) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:123) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:114) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:67) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.cli.Command.main(Command.java:88) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:91) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:84) [elasticsearch-5.5.1.jar:5.5.1] [2017-08-01T14:10:57,843][WARN ][o.e.b.BootstrapChecks ] [VAfWGGZ] max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536] [2017-08-01T14:10:57,844][WARN ][o.e.b.BootstrapChecks ] [VAfWGGZ] max number of threads [1024] for user [maserati] is too low, increase to at least [2048] [2017-08-01T14:10:57,844][WARN ][o.e.b.BootstrapChecks ] [VAfWGGZ] max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] [2017-08-01T14:10:57,844][WARN ][o.e.b.BootstrapChecks ] [VAfWGGZ] system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

針對文件描述符，調成 65536 ulimit -n 65536，若是提示沒有權限，則能夠在用戶的 .bash_profile 中增長一行，退出用戶從新登錄就能夠。

針對 max number of threads 問題，修改 /etc/security/limits.d/90-nproc.conf 。

* soft nproc 2048 root soft nproc unlimited

針對 max virtual memory areas ，修改 /etc/sysctl.conf。若是沒有，就新增一行。

vm.max_map_count = 262144

針對 system_call_filter 能夠，經過修改配置文件（elasticsearch.yml）關掉這個參數。

bootstrap.system_call_filter: false 

四、訪問，出現下面的結果表示啓動成功。

[root@iZ627x15h6pZ cloud]# curl http://localhost:9200 { "name" : "VAfWGGZ", "cluster_name" : "elasticsearch", "cluster_uuid" : "J9Tm5R2zRt2PkOSwtXj5Wg", "version" : { "number" : "5.5.1", "build_hash" : "19c13d0", "build_date" : "2017-07-18T20:44:24.823Z", "build_snapshot" : false, "lucene_version" : "6.6.0" }, "tagline" : "You Know, for Search" }

Logstash 安裝

一、下載並解壓 Logstash，本文用的 Logstash-5.5.1 版本

二、建立一個簡單的配置文件 logstash_test.conf

input { stdin { } } output { stdout { codec => rubydebug } }

三、啓動 logstash

./bin/logstash -f logstash_test.conf 

出現這些信息，表示啓動成功了。

[2017-08-01T13:58:38,437][INFO ][logstash.pipeline ] Pipeline main started The stdin plugin is now waiting for input: [2017-08-01T13:58:38,532][INFO ][logstash.agent ] Successfully started Logstash API endpoint {:port=>9600}

四、與ElasticSearch配合。

Kibana 安裝

一、下載 Kibana

二、修改配置

//啓動端口 由於端口受限 因此變動了默認端口 server.port: 5601 //啓動服務的ip server.host: "本機ip" //elasticsearch地址 elasticsearch.url: "http://localhost:9200」

三、啓動程序

./bin/kibana

四、訪問查看Kibana啓動是否成功，並檢索查看數據

http://localhost:5601
