ElasticSearch（三）mac安装

1.首先要安装jdk

2.到官网或是用brew下载ElasticSearch 安装包，这边我们选择在官网下载对应的安装包 https://www.elastic.co/cn/downloads/elasticsearch

3.解压缩到对应的目录下，我们解压缩到了 /usr/local/elasticsearch-6.5.2

解压缩后的相关目录如下：

4.快速启动

1).进入到bin目录下，执行elasticsearch脚本，sh elasticsearch 或 ./elasticsearch

2).我们可以看到started关键字，表示已经启动成功，绑定端口为9200

[2018-12-12T09:36:45,853][INFO ][o.e.x.s.t.n.SecurityNetty4HttpServerTransport] [PX7a_3A] publish_address {127.0.0.1:9200}, bound_addresses {[::1]:9200}, {127.0.0.1:9200}

[2018-12-12T09:36:45,854][INFO ][o.e.n.Node ] [PX7a_3A] started

3).查看es jvm进程

➜ ~ jps -l |grep Elasticsearch
1052 org.elasticsearch.bootstrap.Elasticsearch

4).或是我们可以用curl http://localhost:9200/?pretty检查是否启动成功

➜ ~ curl http://localhost:9200/\?pretty

{
"name" : "PX7a_3A",
"cluster_name" : "elasticsearch",  //集群名称（默认的集群名称就是elasticsearch）
"cluster_uuid" : "mnnG3X4aSpakShysGdqy0w",
"version" : {
"number" : "6.5.2",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "9434bed",
"build_date" : "2018-11-29T23:58:20.891072Z",
"build_snapshot" : false,
"lucene_version" : "7.5.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}

5).我们发现control+c停止了Elasticsearch,有closed关键字，所以要进行后台启动

[2018-12-12T09:48:36,732][INFO ][o.e.n.Node ] [PX7a_3A] stopped
[2018-12-12T09:48:36,732][INFO ][o.e.n.Node ] [PX7a_3A] closing ...
[2018-12-12T09:48:36,747][INFO ][o.e.n.Node ] [PX7a_3A] closed

6).后台启动Elasticsearch

执行命令 sh elasticsearch -d
