root@bt:/opt/elasticsearch-0.19.2#unzip elasticsearch-0.19.2.zip

3.运行

root@bt:/opt/elasticsearch-0.19.2# bin/elasticsearch  //后台运行

root@bt:/opt/elasticsearch-0.19.2# bin/elasticsearch -f //前台运行

4.环境变量

ES_JAVA_OPTS

ES_HEAP_SIZE

ES_MIN_MEM(defaults to 256m)

ES_MAX_MEM(defaults to 1gb)

5.命令行参数

$bin/elasticsearch -f -Xmx2g -Xms2g -Des.index.storage.type=memory

-X and -D

When set,both override anything set using either JAVA_OPTS or ES_JAVA_OPTS

6.Running As a Service

下载elasticsearch-servicewrapper https://github.com/elasticsearch/elasticsearch-servicewrapper

解压到elasticsearch/bin目录下

root@bt:/opt/elasticsearch-0.19.2# bin/service/elasticsearch console  //控制台启动

root@bt:/opt/elasticsearch-0.19.2# bin/service/elasticsearchstart  //后台启动

root@bt:/opt/elasticsearch-0.19.2# bin/service/elasticsearchstop  //停止服务

root@bt:/opt/elasticsearch-0.19.2# bin/service/elasticsearchinstall  //Install elasticsearchto run on system startup (init.d / service).

root@bt:/opt/elasticsearch-0.19.2# bin/service/elasticsearchremove  //Removes elasticsearchfrom system startup (init.d / service).

7.重要配置

修改limits.conf，设置最大打开文件数和memlock限制

vim/etc/security/limits.conf

*   soft   nofile  unlimited

*   hard   nofile  unlimited

*   -  memlock unlimited

ulimit -lunlimited

ulimit -n100000

 

设置ES能够分配的JVM内存大小，建议MIN和MAX设置一样大，避免频繁的分配内存（默认单位MB），根据服务器内存的大小，一般分配60%左右。

root@bt:/opt/elasticsearch-0.19.2#vim bin/service/elasticsearch.conf

set.default.ES_MIN_MEM=256

set.default.ES_MAX_MEM=1024

 

锁定内存

root@bt:/opt/elasticsearch-0.19.2#vim config/elasticsearch.yml

 bootstrap.mlockall: true

 

8.安装elasticsearch-head

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

open http://localhost:9200/_plugin/head/
