ubantu elasticsearch服务搭建

1、jdk 1.8以上，elasticsearch是java开发的

[root@VM_58_118_centos sgconfig]# java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

elasticsearch2.3.5的安装、选择2.3.5版本，是想生产线的config和plugins能拿来用，不用考虑head、ik分词、search-guard-2、search-guard-ssl版本对应问题。

4、elasticsearch安装
4.1、安装jdk1.8

4.2、下载es安装包：https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.5/elasticsearch-2.3.5.tar.gz

4.3、通过crt复制到虚拟机 /usr/share/elasticsearch下

4.4、解压：tar -zxvf elasticsearch-2.3.5.tar.gz

4.5、vi /usr/share/elasticsearch/config/elasticsearch.yml

     配置：

    cluster.name: lwx  ##记得别把空格删掉了

    node.name: es1

    http.port: 9200

    path.data: /opt/data/esdata

4.6、安装head插件：

    /usr/share/elasticsearch/bin/plugin install mobz/elasticsearch-head

4.7、启动es：

    groupadd bigdata

    useradd -c "elastic" -d /home/elastic -g bigdata elastic

    passwd elastic

    chmod 774 -R /opt

    chown -R elastic:bigdata /usr/share/elasticsearch-2.3.5

    su elastic

    /usr/share/elasticsearch/bin/elasticsearch -d

　　

/data目录下要参照生产线建立起对应的目录，并给到权限

4.8、在浏览器输入：http://112.74.168.224:9200/_plugin/head/

4.9 ik分词、elasticsearch-guard、elasticsearch-elasticsearchssl安装
bin/plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.5.3/elasticsearch-analysis-ik-5.5.3.zip
bin/plugin install https://github.com/medcl/elasticsearch-guard-2/releases/download/v5.5.3/elasticsearch-guard-2.zip
bin/plugin install https://github.com/medcl/elasticsearch-guard-ssl/releases/download/v5.5.3/elasticsearch-guard-ssl.zip

实际搭建中，/usr/share/elasticsearch/config/* 及 /usr/share/elasticsearch/plugins/*都是从生产环节cp得到

利用sgadmin.sh根据对search-guard初始化...

./plugins/search-guard-2/tools/sgadmin.sh -cn syhuo -h 0.0.0.0 -cd plugins/search-guard-2/sgconfig -ks plugins/search-guard-2/sgconfig/syhuo-keystore.jks -kspass 86337898 -ts plugins/search-guard-2/sgconfig/truststore.jks -tspass 86337898 -nhnv

安装OK后重启elasticsearch服务

elastic用户下启动：
/usr/share/elasticsearch/bin/elasticsearch -d

查看端口： netstat -ntpl | grep 9200

确认服务： http://112.74.168.224:9200/_plugin/head/
