我在樱花的VPS上安装了CentOS 7(x86_64)和elasticsearch

成为根源。

● 安装 Java

yum install java
java -version

版本显示会如下所示。

openjdk version "1.8.0_141"
OpenJDK Runtime Environment (build 1.8.0_141-b16)
OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)

●安装Elasticsearch

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
vim /etc/yum.repos.d/elasticsearch.repo

创建一个新文件，其内容如下所述。

[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

执行下面的命令。

yum install elasticsearch

systemctl enable elasticsearch

systemctl start elasticsearch


curl localhost:9200

[root@tk2-259-39318 ~]# curl localhost:9200
{
  "name" : "skdoA54",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "ERp54wHgQxamJAXrpncmCA",
  "version" : {
    "number" : "5.5.2",
    "build_hash" : "b2f0c09",
    "build_date" : "2017-08-14T12:33:14.154Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.0"
  },
  "tagline" : "You Know, for Search"
}

●安装Kuromoji

/usr/share/elasticsearch/bin/elasticsearch-plugin install analysis-kuromoji

如果显示已安装了analysis-kuromoji，那就没问题。

systemctl restart elasticsearch

当连接到本地主机失败时，会显示“拒绝连接”。

  vi /etc/elasticsearch/elasticsearch.yml

  network.host: "localhost"
  http.port: 9200

  systemctl restart elasticsearch
