一、Linux下安装ElasticSearch

1、检测是否安装了Elasticsearch

1 ps aux |grep elasticsearch

2、安装JDK

3、下载Elasticsearch

1 wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.0.0.tar.gz

解压Elasticsearch

tar -zxvf elasticsearch-6.0.0.tar.gz

移动Elasticsearch到/usr/local/elasticsearch

1 mv elasticsearch-6.0.0 /usr/local/elasticsearch

4、修改配置文件

进入/usr/local/elasticsearch/config目录，使用vi编辑器

1 vi elasticsearch.yml

1 network.host: 192.168.181.201
2 discovery.zen.ping.unicast.hosts: ["192.168.181.201"]

修改/etc/sysctl.conf否则会出现

max virutal memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

vm.max_map_count=262144

退出保存后执行如下命令:

1 sysctl -p

使用vi编辑器，修改/etc/security/limits.conf文件，在文件末尾添加如下代码,否则会出现

max number of threads [3750] for user [xxx] is too low, increase to at least [4096]

1 # sanglp为登录服务器的用户名
2
3 sanglp soft nofile 65536
4 sanglp hard nofile 65536
5 sanglp soft nproc  4096
6 sanglp hard nproc  4096

切记退出重新登录。

5、启动Elasticsearch

进入/usr/local/elasticsearch目录之中，输入以下命令，开始Elasticsearch服务：

1 ./bin/elasticsearch
