  • elastic search安装

    参考:https://www.elastic.co/guide/en/elasticsearch/reference/current/rpm.html

    前提:安装好了java

    步骤:

       1.rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

       2.sudo vi /etc/yum.repos.d/elasticsearch.repo

    [elasticsearch-6.x]
    name=Elasticsearch repository for 6.x packages
    baseurl=https://artifacts.elastic.co/packages/6.x/yum
    gpgcheck=1
    gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
    enabled=1
    autorefresh=1
    type=rpm-md


    3.
    sudo yum install elasticsearch ,至此已经安装好了。

    4.启动elastic search

    1)查看本机使用的是init还是systemd
      ps -p 1
    2)若是init,则

      sudo chkconfig --add elasticsearch

      sudo -i service elasticsearch start#启动

      sudo -i service elasticsearch stop#停止

    3)若是systemd

      sudo /bin/systemctl daemon-reload

          sudo /bin/systemctl enable elasticsearch.service


      sudo systemctl start elasticsearch.service#启动

          sudo systemctl stop elasticsearch.service#停止

        5.测试

    curl 127.0.0.1:9200

    返回结果如下:

    {
    "name" : "ad1suuQ",
    "cluster_name" : "elasticsearch",
    "cluster_uuid" : "RLFqfSMYSra7IHR07I9XrQ",
    "version" : {
    "number" : "6.3.0",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "424e937",
    "build_date" : "2018-06-11T23:38:03.357887Z",
    "build_snapshot" : false,
    "lucene_version" : "7.3.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
    },
    "tagline" : "You Know, for Search"
    }

     

     6若是安装集群,默认为三个节点,则修改config/elasticsearch.yml

     

    # Use a descriptive name for your cluster:
    #设置集群名,三个节点集群名是相同的
    cluster.name: testcluster2
    #
    # ------------------------------------ Node ------------------------------------
    #
    # Use a descriptive name for the node:
    #
    #换个节点名字,三个节点的节点名不同,其他两个节点分别为node2,node3
    node.name: node1

    network.host: 0.0.0.0

    discovery.zen.ping.unicast.hosts: ["10.101.4.1","10.101.4.2","10.101.4.3"] #候选主节点地址

    #如果启用了 HTTP 端口,那么此属性会指定是否允许跨源 REST 请求。

    http.cors.enabled: true

    #如果 http.cors.enabled 的值为 true,那么该属性会指定允许 REST 请求来自何处。
    http.cors.allow-origin: "*"

    保存后分别启动三个节点,打开elastic-head观察是否成功,当出现以下页面时代表已经搭建成功:
