ElasticSearch、Kibana Setup

    最近自己找了三台测试服务器学着装了es。记录一下安装过程。

    ElasticSearch

    一、下载安装

    (1) 下载

    wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.6.2-x86_64.rpm
    

    (2)

    sudo rpm --install elasticsearch-7.6.2-x86_64.rpm
    

    默认路径/etc/elasticsearch/

    二、配置

    3、可能出现的问题

    (1)max number of threads [1024] for user [elasticsearch] is too low, increase to at least [4096]

    vim /etc/security/limits.d/90-nproc.conf

    (2)max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

    vim /etc/sysctl.conf
    添加vm.max_map_count=262144
    

    (3)【CENTOS6才会】system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

    在es.yml中添加
    bootstrap.system_call_filter: false
    

    (4)ERROR: bootstrap checks failed memory locking requested for elasticsearch process but memory is not locked

    vim /etc/security/limits.conf
    添加
    * soft memlock unlimited 
    * hard memlock unlimited
    
    4、配置文件修改
    cluster.name: test-cluster
    node.name: [HOSTNAME]
    path.data: /cache1/elasticsearch/data
    path.logs: /cache1/elasticsearch/logs
    network.host: 0.0.0.0
    node.master: true
    node.data: true
    http.port: [PORT]
    bootstrap.memory_lock: true
    

    第一台启动的机器配置

    cluster.initial_master_nodes: ["HOSTNAME"]
    

    其他加入的机器配置

    discovery.seed_hosts: ["[MASTER-ELIGIBLE IP]"]
    
    5、修改jvm配置

    修改jvm.options
    (1)修改-XmsXmx
    (2)修改gc文件配置(默认是在es路径的logs下)

    6、关闭swap

    edit the /etc/fstab file and comment out any lines that contain the word swap.

    7、修改文件句柄数

    Kinana

    一、centos version

    如果是centos6,会有一个glibc版本过低的异常

    建议使用rpm方式安装。本次也是使用rpm方式安装。

    二、安装

    1、下载
    wget https://artifacts.elastic.co/downloads/kibana/kibana-7.6.2-x86_64.rpm
    
    2、安装
    sudo rpm --install kibana-7.6.2-x86_64.rpm
    
    3、default path
    • 默认配置文件地址:/etc/kibana
    • 默认日志地址:/var/log/kibana
    4、配置修改

    修改配置文件kibana.yml

    server.port: 5601 // kibana端口
    server.host: 0.0.0.0 // 对外暴露
    elasticsearch.hosts: ["http://localhost:port"] // es的地址
    
    5、command

    service kibana start/stop/status
