本文介紹安裝 logstash 2.2.0 和 elasticsearch 2.2.0,作業系統環境版本是 CentOS/Linux 2.6.32-504.23.4.el6.x86_64。
安裝 JDK 是必須的,一般作業系統都會有,只是版本的問題,後面會提到。
而 Kibana 只是一個用純 JavaScript 寫的前端 UI。一定要注意 Kibana 的版本,它會要求 ES 的版本。比如 Kibana 3 要求 Elasticsearch 至少 0.9.9 或更高;Kibana 4.5 要求 ES 至少 2.3.0 或更高。
假設,ELK 都位於 10.1.8.166 機器上。
Elasticsearch
Elasticsearch主頁
Elasticsearch(簡稱,ES)提供 ZIP、TAR、DEB 和 RPM 包。但 Github 上提供了一個針對中文環境的 Elasticsearch-RTF,RTF 即 Ready To Fly,它是一個繼承了基本外掛(如服務封裝、中文分詞、mapper-attachments、transport-thrift、tools.carrot2 等)的並帶有示例程式的可直接上手的簡易工程版本,換句話說,幫你入門的。本文針對 Elasticsearch-RTF 為例。基本上,elasticsearch 解壓後就能使用。
假設你已經從 Github 上下載 elasticsearch-rtf,名為 elasticsearch-master.zip,並上傳到你的 Linux 伺服器 /usr/local/elasticsearch目錄(如果沒有,就用 mkdir 命令建立一個)。
現在,解壓,並重新命名資料夾:
[root@vcyber local]# cd /usr/local/elasticsearch
[root@vcyber local]# unzip elasticsearch-master.zip
[root@vcyber elasticsearch]# ls
elasticsearch-master elasticsearch-master.zip
[root@vcyber local]# mv elasticsearch-master elasticsearch
[root@vcyber elasticsearch]# ls
elasticsearch elasticsearch-master.zip
嘗試執行 elasticsearch:
Linux 環境:
[root@vcyber elasticsearch]# pwd
/usr/local/elasticsearch/elasticsearch
[root@vcyber elasticsearch]# bin/elasticsearch
Windows 環境,執行相應的 .bat 檔案,即 elasticsearch.bat。
但報錯了:
[root@vcyber elasticsearch]# bin/elasticsearch
Exception in thread "main" java.lang.RuntimeException: Java version: Oracle Cooration 1.7.0_51 [Java HotSpot(TM) 64-Bit Server VM 24.51-b03] suffers from crical bug https://bugs.openjdk.java.net/browse/JDK-8024830 which can cause dataorruption.
Please upgrade the JVM, see http://www.elastic.co/guide/en/elasticsearch/referce/current/_installation.html for current recommendations.
If you absolutely cannot upgrade, please add -XX:-UseSuperWord to the JAVA_OPT environment variable.
Upgrading is preferred, this workaround will result in degraded performance.
at org.elasticsearch.bootstrap.JVMCheck.check(JVMCheck.java:123)
at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:283)
at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:3
Refer to the log for complete error details.
大意是:Java 執行時異常,本機版本 JDK 有 bug……讓升級 JVM。如果實在不能升級,就向 JAVA_OPT 環境變數新增 -XX:-UseSuperWord 選項。
於是,看一下本機的Java 版本:
[root@vcyber elasticsearch]# java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
[root@vcyber elasticsearch]# echo $JAVA_HOME
/usr/java/jdk1.7.0_51
[root@vcyber elasticsearch]#
版本是 1.7.0_51。再在官網查了一下,說:
“Elasticsearch requires at least Java 7. Specifically as of this writing, it is recommended that you use the Oracle JDK version 1.8.0_72. Java installation varies from platform to platform so we won’t go into those details here. Oracle’s recommended installation documentation can be found on Oracle’s website. Suffice to say, before you install Elasticsearch, please check your Java version first by running (and then install/upgrade accordingly if needed):”
大意是,ES 至少要求 7,推薦使用 1.8.0_72。
那就刪除之前的版本,按個新的吧。先刪掉之前的 JDK,然後再用 yum 按個新的:
[root@vcyber elasticsearch]# yum list installed | grep java
[root@vcyber elasticsearch]# yum list installed | grep jdk
jdk.x86_64 2000:1.7.0_51-fcs installed
[root@vcyber elasticsearch]# yum -y remove jdk.x86_64
……
[root@vcyber elasticsearch]#yum -y install java-1.8.0-openjdk*
……
注意:java-1.8.0-openjdk*”,後面有個星號,即安裝 java 全部相關的東西~
安裝完成後,設定 JDK 的環境變數:
[root@vcyber elasticsearch]# export JAVA_HOME=/usr/lib/jvm/java-1.8.0
[root@vcyber elasticsearch]# export PATH=$JAVA_HOME/bin:$PATH
[root@vcyber elasticsearch]# export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
[root@vcyber elasticsearch]# java -version
openjdk version "1.8.0_71"
OpenJDK Runtime Environment (build 1.8.0_71-b15)
OpenJDK 64-Bit Server VM (build 25.71-b15, mixed mode)
[root@vcyber elasticsearch]# echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0
[root@vcyber elasticsearch]#
另外,JDK 安裝在了我機器的 /usr/lib/jvm 目錄下,自己確認一下你的路徑。你可以把環境變數的設定放到 profile 裡,一勞永逸。
再次執行:
[root@vcyber elasticsearch]# bin/elasticsearch
Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root.
at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:93)
at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:144)
at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:285)
at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)
Refer to the log for complete error details.
[root@vcyber elasticsearch]#
又報錯,elasticsearch 不能用 root 使用者執行,那就建立一個:
[root@vcyber elasticsearch]# groupadd es
[root@vcyber elasticsearch]# useradd -g es es
[root@vcyber elasticsearch]# passwd es
Changing password for user es.
New password:
BAD PASSWORD: it is WAY too short
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
[root@vcyber elasticsearch]#
[root@vcyber elasticsearch]# chown -R root .
[root@vcyber elasticsearch]# chown -R es .
[root@vcyber elasticsearch]# chgrp -R es .
[root@vcyber elasticsearch]# ls -l
total 4
drwxr-xr-x 7 es es 4096 Mar 1 03:07 elasticsearch
[root@vcyber elasticsearch]#
ES 2.* 版本已經不允許用 root 使用者執行了,但是 1.* 版本無所謂。
重新開啟一個終端,用 es 使用者登入,並執行 elasticsearch:
[root@vcyber ~]$ cd /usr/local/elasticsearch/elasticsearch
[root@vcyber elasticsearch]$ bin/elasticsearch
[2016-03-01 05:11:48,413][WARN ][bootstrap ] unable to install syscall filter: seccomp unavailable: CONFIG_SECCOMP not compiled into kernel, CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER are needed

……
此時,在另一個終端,訪問 elasticsearch:
[root@vcyber elasticsearch]# curl -X GET http://localhost:9200
{
"name" : "Captain Savage",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "2.1.1",

"build_timestamp" : "2015-12-15T13:05:55Z",
"build_snapshot" : false,
"lucene_version" : "5.3.1"
},
"tagline" : "You Know, for Search"
}
[root@vcyber elasticsearch]#
ES 已經安裝成功。
配置 ES
但此時,ES 不能通過IP訪問,最好修改 config/elasticsearch.yml,配置一下 ES。
首先,找到“network.host”行,新增一行:
network.host: your id address
就能通過IP,或瀏覽器訪問。
再找到“http.port”行,新增一行:
http.port: 9200
否則,ES 每次啟動時,埠可能會變(埠被佔用,ES 自己會改埠)~
如果還不能正常啟動 ES,並提示埠被佔用,就檢視一下什麼程式佔用 9200 埠,kill 掉,重啟 ES 就行。
我遇到的,Java 把 9200 埠占用了。
安裝 Head 外掛
Head 是一個用來監控 ES 狀態的客戶端外掛,可以為初學使用者提供很多便利,例如,使用 Head 提供的 HTTP 客戶端,通過 HTTP 方式來操作 ES。
先檢視你的 ES 都有哪些外掛:
[root@vcyber ~]# cd /usr/local/elasticsearch/elasticsearch
[root@cyber elasticsearch]# bin/plugin list
Installed plugins in /usr/local/elasticsearch/elasticsearch/plugins:
- elasticsearch-analysis-mmseg-1.7.0
- elasticsearch-analysis-stconvert-1.6.1
- elasticsearch-analysis-pinyin-1.5.2
- elasticsearch-analysis-ik-1.7.0
[root@vcyber elasticsearch]#
大部分是關於中文分詞的,沒有 Head 外掛。
ES 支援線上和本地安裝 Head。本地安裝時,從 Github 上下載 Head 外掛,然後上傳到你的 ES 伺服器,比如,Elasticsearch/plugins 目錄。
下面是線上安裝:
[root@vcyber ~]# cd /usr/local/elasticsearch/elasticsearch/
[root@vcyber elasticsearch]# bin/plugin install mobz/elasticsearch-head
-> Installing mobz/elasticsearch-head...
Trying https://github.com/mobz/elasticsearch-head/archive/master.zip ...

NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify)
Installed head into /usr/local/elasticsearch/elasticsearch/plugins/head
如果命令使用的是“mobz/elasticsearch-head”,那麼 ES 將自己聯網從 Github 下載再安裝。
但是報錯了,說校驗和有問題。加上“-v”選項,這次換本地安裝,而且是 zip 壓縮包(從 Github 上下載的),即“file:plugins/elasticsearch-head-master.zip”,再執行一下:
[root@vcyber elasticsearch]# bin/plugin install -v file:plugins/elasticsearch-head-master.zip
-> Installing from file:plugins/elasticsearch-head-master.zip...
Trying file:plugins/elasticsearch-head-master.zip ...
Downloading .........DONE
Verifying file:plugins/elasticsearch-head-master.zip checksums if available ...
NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify)
- Plugin information:
Name: head
Description: head - A web front end for an elastic search cluster
Site: true
Version: master
JVM: false
Installed head into /usr/local/elasticsearch/elasticsearch/plugins/head
注意:install 選項,ES 的 2.* 版本,都不帶“-”橫線選項,即“-install”。
注意:若是本地安裝,而且,你把 Head 壓縮包放到了 Elasticsearch/plugins 目錄下,安裝後,一定要將 Elasticsearch-head zip 壓縮包刪掉,否則啟動 ES 時會報“不能初始化外掛”錯誤。
[2016-03-02 07:06:16,547][WARN ][bootstrap ] unable to install syscall filter: seccomp unavailable: CONFIG_SECCOMP not compiled into kernel, CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER are needed

myfirestidx 是我之前通過命令列自己建的。
Elasticsearch Head 就成功安裝了。
安裝 Marvel 圖形化監控外掛

[root@vcyber elasticsearch]#
雖然安裝成功了,但此版本 kopf 不支援我的 ES 版本。

logstash
logstash主頁
logstash 提供各種安裝包,包括 tar.gz,ZIP,DEB 和 RPM。另外,又提供了一個包含所有外掛的壓縮包——logstash-all-plugins-2.2.0.tar.gz 。本文以它為例。解壓後,配置 logstash,執行即可。
在 /usr/local 下建立目錄 logstash:
[root@vcyber local]# cd /usr/local
[root@vcyber local]# pwd
/usr/local
[root@vcyber local]# mkdir logstash
[root@vcyber local]#
上傳 logstash 到該目錄。然後,解壓並配置 logstash 配置檔案:
[root@vcyber local]# cd logstash
[root@vcyber logstash]# ls
logstash-all-plugins-2.2.0.tar.gz
[root@vcyber logstash]# tar zxf logstash-all-plugins-2.2.0.tar.gz
logstash-2.2.0 logstash-all-plugins-2.2.0.tar.gz
[root@vcyber logstash]# cd logstash-2.2.0
[root@vcyber logstash-2.2.0]# vi logstash.conf
[root@vcyber logstash-2.2.0]#
檔案內容如下:
input{
stdin{}
}
output{
stdout{}
}
這個配置是最簡單,輸入是終端命令列,輸出也是終端命令列。
執行 logstash:
[root@vcyber logstash-2.2.0]# bin/logstash agent -f logstash.conf
hello world
hello world 2
Settings: Default pipeline workers: 2
Logstash startup completed
2016-02-28T22:37:06.130Z vcyber hello world
2016-02-28T22:37:06.132Z vcyber hello world 2
logst 已經成功安裝。其中,agent 表示執行Agent模式,-f 表示指定配置檔案,-p 表示埠,命令列引數可以參考logstash command-lines flags。
另外,你可以檢視 logstash 都安裝了哪些外掛。

Kibana
Kibana 主頁
chenryn 增強版的 Kibana
你得搞一個 Kibana 3.0 並上傳你伺服器的 /usr/local/Kibana 目錄下,沒有建立一個,然後用 unzip 解壓(github 下載的是 zip 檔案)。
[root@vcyber /]# cd /usr/local/kibana/
[root@vcyber kibana]# ls
exampledata kibana-3.0 kibana-4.0 kibana-5.0
[root@vcyber kibana]#
你可以看到,我有三個版本,4.0 和 5.0 沒有安裝成功(總提示 node.js 報錯)~Kibana 這三個主要版本差距很大~
簡單介紹一下,你就知道,Kibana 的每個版本差距有多大。Logstash 早期曾經自帶了一個特別簡單的 Logstash-Web,用來檢視 ES 資料。後來, Rashid Khan 用 PHP 寫了一個更好的 Web,取名 Kibana,釋出於 2011年12月11日。2012年8月19日,Rashid Khan 用 Ruby 重寫了一遍,叫 Kibana 2,。因為,Logstash 也是用 Ruby 寫的,所以就代替了 Logstash-Web。2014年2月,此人,用 AngularJS 又重寫了一遍,(我靠,真是服了他了~),叫 Kibana 3。2014年4月,Kibana 3 停止開發,全面致力於 Kibana 4。到 2015年初,釋出了用 JRuby 做後端的 beta 版,但3月正式推出時卻使用 node.js 做後端。(我靠靠,服了都被他用遍了)
到其 src 目錄下:
[root@vcyber kibana]# cd kibana-3.0/src
[root@vcyber src]# ls
app config.js css favicon.ico font img index.html vendor
[root@vcyber src]#
修改其 config.js 檔案,新增對 ES 的訪問。無論是看檔案內容,還是看字尾名,你能猜到,就是手動去改 JavaScript 檔案而已:
elasticsearch: [http://10.1.8.166:9200](http://10.1.8.166:9200/),
我 ES 伺服器地址是 10.1.8.166,注意,屁股後面的逗號,絕對是有的。如果該檔案配置錯了,當你訪問 Kibana 時,介面什麼都看不到~
接下來,把 Kibana 搞成一個 Web 站點。tomcat、Python、Nginx 都行,我暫時用 Python。只要把 Kibana 的 src 目錄釋出出去就行。
注意你當前的位置,執行如下命令,就能把 Kibana 做成一個 Web 站點:
[root@vcyber src]# pwd
/usr/local/kibana/kibana-3.0/src
[root@vcyber src]# python –m SimpleHTTPServer 8000
其中,SimpleHTTPServer 是 Python 模組名,區分大小寫的;8000 是 Web 站點的埠。
這樣,你就能通過 http://10.1.8.166:8000 訪問 Kibana。
但是,頁面報錯了:“Connection Failed”:
提示,Kibana 不能連線 ES。至於原因,從 ES 1.4 版本開始,它增強了安全性。寫得很清楚,照著做就行(事後才知道)。~但問題是,這些具體東西,在官網沒找到(我是沒找到),而且連 Kibana 3.0 的文件,都已經沒有了~錯誤資訊所說的:“http.cors” 相關配置,在 Elasticsearch.yml 中,也沒給出~事實上,還真是寫這兩個配置。
進入到 ES 的 config 目錄:
[root@vcyber src]# cd /usr/local/elasticsearch/
[root@vcyber elasticsearch]# ls
elasticsearch-1.7.1 elasticsearch-2.2.0
[root@vcyber elasticsearch]# cd elasticsearch-1.7.1/config/
[root@vcyber config]#
我有兩個 ES 版本,Kibana 訪問的是 1.7 那個版本。
修改 Elasticsearch.yml 檔案,新增如下內容:
http.cors.allow-origin: http://10.1.8.166:8000
http.cors.enabled: true
其中,http.cors.allow-origin 一行表明,誰可以訪問 ES。若讓所有域名都可以訪問,寫成 “*”~
本例寫具體的 IP 地址和埠。
