ELK初学搭建 elasticsearch

1.环境准备

centos6.8_64 mini

IP:192.168.10.78

tar包：

logstash-2.4.0.tar.gz

elasticsearch-2.4.0.tar.gz

kibana-4.6.1-linux-x86_64.tar.gz

JDK环境

elasticsearch logstach kibana java
V2.4 V2.4 V4.6.1 V1.8.0_111
1.1环境准备
  1. [root@localhost ~]# yum install java-1.8.0-openjdk* -y 
  2. [root@localhost ~]# export JAVA_HOME=/usr/lib/jvm/java-1.8.0 
  3. [root@localhost ~]# export PATH=$JAVA_HOME/bin:$PATH 
  4. [root@localhost ~]# export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 
  5. [root@localhost ~]# java -version 
  6. openjdk version "1.8.0_111" 
  7. OpenJDK Runtime Environment (build 1.8.0_111-b15) 
  8. OpenJDK 64-Bit Server VM (build 25.111-b15, mixed mode) 

此时jdk环境已经正常可用。

2.软件上传之服务器并解压到/usr/local目录下

解压，并重新命名文件夹：

[root@localhost ~]# xvf elasticsearch-2.4.0.tar.gz

[root@localhost ~]# mv elasticsearch-2.4.0 /usr/local/elasticsearch

同理 将这三个软件解压...

3. 运行软件

  1. [root@localhost elasticsearch]# ./bin/elasticsearch 
  2. Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root. 
  3. at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:94) 
  4. at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:160) 
  5. at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:286) 
  6. at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35) 
  7. Refer to the log for complete error details. 
  8. [root@localhost elasticsearch]#  

运行报错，发现elasticsearch不允许在root下运行，解决：

  1. [root@localhost elasticsearch]# groupadd es 
  2. [root@localhost elasticsearch]# useradd -g es es 
  3. [root@localhost elasticsearch]# useradd -g es es 
  4. [root@localhost elasticsearch]# passwd es 
  5. Changing password for user es. 
  6. New password:  
  7. BAD PASSWORD: it is based on a dictionary word 
  8. Retype new password:  
  9. passwd: all authentication tokens updated successfully. 
  10. [root@localhost elasticsearch]# chown -R root . 
  11. [root@localhost elasticsearch]# chown -R es . 
  12. [root@localhost elasticsearch]# chgrp -R es . 
  13. [root@localhost elasticsearch]# ls -l 
  14. total 56 
  15. drwxr-xr-x 2 es es 4096 Nov 7 17:25 bin 
  16. drwxr-xr-x 3 es es 4096 Nov 7 19:37 config 
  17. drwxrwxr-x 3 es es 4096 Nov 7 17:34 data 
  18. drwxr-xr-x 2 es es 4096 Nov 7 17:25 lib 
  19. -rw-rw-r-- 1 es es 11358 Aug 24 00:46 LICENSE.txt 
  20. drwxrwxr-x 2 es es 4096 Nov 7 17:34 logs 
  21. drwxrwxr-x 5 es es 4096 Aug 29 17:23 modules 
  22. -rw-rw-r-- 1 es es 150 Aug 24 00:46 NOTICE.txt 
  23. drwxrwxr-x 4 es es 4096 Nov 7 17:50 plugins 
  24. -rw-rw-r-- 1 es es 8700 Aug 24 00:46 README.textile 

此时，ES 不能通过IP访问，最好修改 config/elasticsearch.yml，配置一下 ES。

首先，找到“network.host”行，添加一行：

network.host: 192.168.10.78

再找到“http.port”行，添加一行：

http.port: 9200

否则，ES 每次启动时，端口可能会变（端口被占用，ES 自己会改端口）~

如果还不能正常启动 ES，并提示端口被占用，就查看一下什么程序占用 9200 端口，kill 掉，重启 ES 就行。

就能通过IP，或浏览器访问。

切换至es用户先运行elasticsearch

  1. [root@localhost ~]# su es 
  2. [es@localhost root]$ cd /usr/local/elasticsearch/ 
  3. [es@localhost elasticsearch]$ ls 
  4. bin config data lib LICENSE.txt logs modules NOTICE.txt plugins README.textile 
  5. [es@localhost elasticsearch]$ ./bin/elasticsearch

此时，在另一个终端，访问 elasticsearch：

  1. [root@localhost ~]# curl -X GET http://192.168.10.78:9200 
  2. { 
  3. "name" : "Egghead", 
  4. "cluster_name" : "elasticsearch", 
  5. "version" : { 
  6. "number" : "2.4.0", 
  7. "build_hash" : "ce9f0c7394dee074091dd1bc4e9469251181fc55", 
  8. "build_timestamp" : "2016-08-29T09:14:17Z", 
  9. "build_snapshot" : false, 
  10. "lucene_version" : "5.5.2" 
  11. } 
  12. "tagline" : "You Know, for Search" 
  13. } 

到这一不，ES 已经安装成功。可用浏览器测试是都正常即可。

Head 插件

Head 是一个用来监控 ES 状态的客户端插件，可以为初学用户提供很多便利，例如，使用 Head 提供的 HTTP 客户端，通过 HTTP 方式来操作 ES。

ES 支持在线和本地安装 Head。本地安装时，从 Github 上下载 Head 插件，然后上传到你的 ES 服务器，比如，Elasticsearch/plugins 目录。

下面是在线安装：

  1. [root@localhost elasticsearch]# ./bin/plugin install mobz/elasticsearch-head 
  2. -> Installing mobz/elasticsearch-head... 
  3. Trying https://github.com/mobz/elasticsearch-head/archive/master.zip ... 
  4. Downloading ...................................................................................................................................................................................................................................................................................................................................................................................................................................DONE 
  5. Verifying https://github.com/mobz/elasticsearch-head/archive/master.zip checksums if available ... 
  6. NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify) 
  7. Installed head into /usr/local/elasticsearch/plugins/head 

用浏览器访问 http://192.168.10.78:9200/_plugin/head

ELK初学搭建(elasticsearch)

logstash-%{type}-2016.11.07是我自己创建的，后续介绍。

至此Elasticsearch Head 就成功安装了。

Marvel 图形化监控插件收费，安装方法同上，本免费党不测试了 哈哈~

安装 kopf 网络插件

[root@localhost elasticsearch]# ./bin/plugin install mobz/elasticsearch-kopf
