环境介绍
System: CentOS7.2 x86_64
hostname: elk-server.huangming.org
IP Address: 10.0.6.42、10.17.83.42
本篇的ELK环境为单机部署方式，即将ELK所有的软件包都安装在一台服务器上，配置如下：
CPU: 4c
Mem: 8G
Disk: 50
一、Elasticsearch安装
1、安装jdk 1.8及以上的版本（安装过程略）
| 1 2 3 4 | [root@elk-server elk] # java -version java version "1.8.0_65" Java(TM) SE Runtime Environment (build 1.8.0_65-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode) |
2、下载Elasticsearch最新版本(目前5.5版本)
| 1 2 3 4 | 使用curl命令下载 tar 包 # curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.2.tar.gz 也可以使用wget命令下载 # wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.2.tar.gz |
3、解压至指定目录(安装目录)/usr/local/下，并将其重命名为elasticsearch (完整的目录应该为/usr/local/elasticsearch)
| 1 2 3 | # tar -zxf elasticsearch-5.5.2.tar.gz -C /usr/local/ # cd /usr/local/ # mv elasticsearch-5.5.2 elasticsearch |
2、创建一个用于运行elasticsearch的普通用户，随后修改elasticsearch家目录的所属权限为该用户；创建elasticsearch数据存储目录/data/elasticsearch
| 1 2 3 4 5 | # groupadd elasticsearch # useradd -g elasticsearch elasticsearch -m # chown -R elasticsearch. /usr/local/elasticsearch # mkdir /data/elasticsearch # chown -R elasticsearch. /data/elasticsearch |
2、修改elasticsearch.yml配置文件
| 1 2 3 4 5 6 | # vim config/elasticsearch.yml cluster.name: my-application #ELK集群名称 path.data: /data/elasticsearch #elasticsearch 数据存储目录 path.logs: /usr/local/elasticsearch/logs #elasticsearch 日志存储路径 network.host: 10.17.83.42 #elasticsearch 监听地址，默认为localhost http.port: 9200 #elasticsearch 监听端口，默认问9200 |
6、修改相关的内核参数
# 打开/etc/security/limits.conf文件，添加以下参数
| 1 2 3 4 | * soft nproc 2048 * hard nproc 16384 * soft nofile 65536 * hard nofile 65536 |
# 修改vm.max_map_count=262144
| 1 | # echo "/etc/sysctl.conf" >> /etc/sysctl.conf |
7、运行elasticsearch (注意：要切换到普通用户运行)
# su - elasticsearch
$ ./bin/elasticsearch
运行elasticsearch
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | [elasticsearch@elk-server ~]$ cd /usr/local/elasticsearch/ [elasticsearch@elk-server elasticsearch]$ . /bin/elasticsearch [2017-08-28T14:51:31,069][INFO ][o.e.n.Node ] [] initializing ...

一般情况我们要求elasticsearch在后台运行，使用命令如下：
| 1 | $ . /bin/elasticsearch -d |
8、检查elasticsearch状态，如下则表示正常运行
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | [root@elk-server elasticsearch] # curl http://10.17.83.42:9200 { "name" : "6eN59Pf" , "cluster_name" : "my-application" , "cluster_uuid" : "cKopwE1iTciIQAiFI6d8Gw" , "version" : { "number" : "5.5.2" , "build_hash" : "b2f0c09" , "build_date" : "2017-08-14T12:33:14.154Z" , "build_snapshot" : false , "lucene_version" : "6.6.0" }, "tagline" : "You Know, for Search" } |
二、Logstash安装
1、下载logstash软件包
| 1 | # wget https://artifacts.elastic.co/downloads/logstash/logstash-5.5.2.tar.gz |
2、解压至指定安装目录
| 1 2 3 4 | # tar -zxf logstash-5.5.2.tar.gz -C /usr/local/ # cd /usr/local/ # mv logstash-5.5.2 logstash |
3、运行logstash
# cd logstash/
# ./bin/logstash -e 'input { stdin { } } output { stdout {} }'
输入”hello world! ”，验证是否正常输出
| 1 2 3 4 5 6 7 8 9 10 11 12 | [root@elk-server logstash] # ./bin/logstash -e 'input { stdin { } } output { stdout {} }' ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Sending Logstash's logs to /usr/local/logstash/logs which is now configured via log4j2.properties [2017-08-28T15:11:33,267][INFO ][logstash.setting.writabledirectory] Creating directory {:setting=> "path.queue" , :path=> "/usr/local/logstash/data/queue" } [2017-08-28T15:11:33,273][INFO ][logstash.setting.writabledirectory] Creating directory {:setting=> "path.dead_letter_queue" , :path=> "/usr/local/logstash/data/dead_letter_queue" } [2017-08-28T15:11:33,300][INFO ][logstash.agent ] No persistent UUID file found.

三、Kibana安装
1、下载kibana
| 1 | # wget https://artifacts.elastic.co/downloads/kibana/kibana-5.5.2-linux-x86_64.tar.gz |
2、解压至安装目录
| 1 2 3 | # tar -zxf kibana-5.5.2-linux-x86_64.tar.gz -C /usr/local/ # cd /usr/local/ # mv kibana-5.5.2-linux-x86_64 kibana |
3、修改配置
| 1 2 3 4 5 6 7 | # cd kibana/ # vim config/kibana.yml server.port: 5601 # 监听端口 server.host: "10.17.83.42" # 指定后端服务器 elasticsearch.url: "http://10.17.83.42:9200" # 指定elasticsearch实例地址 |
4、运行kibana
# ./bin/kibana &
| 1 2 3 4 5 6 7 8 9 10 | [root@elk-server kibana] # ./bin/kibana & [1] 3219 [root@elk-server kibana] # log [07:26:02.496] [info][status][plugin:kibana@5.5.2] Status changed from uninitialized to green - Ready log [07:26:02.604] [info][status][plugin:elasticsearch@5.5.2] Status changed from uninitialized to yellow - Waiting for Elasticsearch log [07:26:02.637] [info][status][plugin:console@5.5.2] Status changed from uninitialized to green - Ready log [07:26:02.682] [info][status][plugin:metrics@5.5.2] Status changed from uninitialized to green - Ready log [07:26:02.930] [info][status][plugin:elasticsearch@5.5.2] Status changed from yellow to green - Kibana index ready log [07:26:02.932] [info][status][plugin:timelion@5.5.2] Status changed from uninitialized to green - Ready log [07:26:02.937] [info][listening] Server running at http: //10 .17.83.42:5601 log [07:26:02.939] [info][status][ui settings] Status changed from uninitialized to green - Ready |
5、验证kibana
在客户端浏览器打开
在该页面提示我们需要创建一个index
首先创建一个kinana默认的index(名称为.kibana),如果输入的index名不存在，则无法创建
查看运行状态及已安装的插件
至此ELK已经搭建完成了，下面来创建一个收集message系统日志的实例
