  • ElasticSearch7.4.2安装Linux步骤详情

    1:下载tar包

    2:tar -zxf 解压

    3:进入解压后的ElasticSearch7.4.2目录,创建data目录,mkdir;用于存储以后的索引数据

    4 :进入config目录,编辑 elasticsearch.yml文件,

    配置如下:

    cluster.name: wjx-elasticsearch  //集群名称:wjx-elasticsearch

    node.name: node-1  //节点名称:node-1,

    path.data: /usr/local/elasticsearch-7.4.2/data  //数据路径:放入刚创建的data目录中

    path.logs: /usr/local/elasticsearch-7.4.2/logs  //r日志路径:放入刚创建的data目录中

    network.host: 0.0.0.0  //用于设置网络接收,允许所有ip地址访问该elasticsearch.

    http.port: 9200       //配置对外访问端口

    cluster.initial_master_nodes: ["node-1"]    //配置master集群节点,目前单节点:node-1 

    5:elastic的启动不能使用root用户,新增elasticsearch用户:useradd esuser

    6:给esuser赋予权限:chown -R esuser /usr/local/elasticsearch-7.4.2/

    7:切换到esuser用户,启动elasticsearch

    8:解决错误:错误信息如下:

    ERROR: [2] bootstrap checks failed
    [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
    [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
