    centos yum安装

    elasticsearch

    $ rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
    $ cat /etc/yum.repos.d/elasticsearch.repo
        [elasticsearch-2.x]
        name=Elasticsearch repository for 2.x packages
        baseurl=http://packages.elastic.co/elasticsearch/2.x/centos
        gpgcheck=1
        gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
        enabled=1
    $ yum install elasticsearch
    

    logstash

    $ rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
    
    // 配置yum
    $ cat /etc/yum.repos.d/logstash.repo
        [logstash-2.3]
        name=Logstash repository for 2.3.x packages
        baseurl=https://packages.elastic.co/logstash/2.3/centos
        gpgcheck=1
        gpgkey=https://packages.elastic.co/GPG-KEY-elasticsearch
        enabled=1
    
    // 安装logstash
    $ yum -y install logstash
    

    kibana

    // 安装key. 
    rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
    
    // 配置yum
    $ vim /etc/yum.repos.d/kibana.repo 
        [kibana-4.5]
        name=Kibana repository for 4.5.x packages
        baseurl=http://packages.elastic.co/kibana/4.5/centos
        gpgcheck=1
        gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
        enabled=1
        
    // 安装kibana
    $ yum install -y kibana
    

    启动准备

    elasticsearch

    设置jvm.options,

    -XX:ParallelGCThreads=3 #3可修改
    

    elasticsearch 不能用root启动;

    groupadd elsearch
    useradd elsearch -g elsearch -p elasticsearch
    su elsearch
    

    修改 /etc/security/limits.conf, 增加:

    elsearch soft nofile 819200
    elsearch hard nofile 819200
    elsearch soft nproc 2048
    elsearch hard nproc 4096
    elsearch soft memlock unlimited
    elsearch hard memlock unlimited
    

    修改 /etc/security/limits.d/90-nproc.conf:

    *          soft    nproc    1024
    

    修改为

    *          soft    nproc    2048
    

    修改 /etc/sysctl.conf。如果在docker中,修改/etc/sysctl.conf文件,需要--privileged权限。:

    vm.max_map_count=655360
    

    这个文件修改后,需要执行:

    sysctl -p
    

    修改配置文件 config/elasticsearch.yml

    cluster.name: myes
    node.name: abcdocker-node-1
    path.data: /home/worker/data/www/src/data/es-date
    path.logs: /home/worker/data/www/src/logs/elasticsearch
    bootstrap.memory_lock: true
    network.host: 172.17.0.2
    http.port: 9200
    

    logstash

    设置jvm.options,

    -XX:ParallelGCThreads=3 #3可修改
    

    kibana

    启动前,需设置elasticsearch访问端口

    修改配置文件 config/kibana.yml

    elasticsearch.url: "http://172.17.0.2:9200"
    server.port: 80
    

    启动命令

    elasticsearch

    进入elasticsearch的bin目录:

    ./elasticsearch -d
    

    -d参数是后台运行

    logstash

    bin/logstash -e 'input { stdin{} } output { stdout{ codec => rubydebug} }'
    

    写入elasticsearch

    bin/logstash -e 'input { stdin{} } output { stdout{ codec => rubydebug} elasticsearch { hosts => ["172.17.0.2:9200"] index => "logstash-%{+YYYY.MM.dd}" } }'
    

    可用配置文件方式,配置文件内容:

    input{
        file{
            path => ["/home/worker/data/www/runtime/demo/err.log"]
            type => "system-log"
            start_position => "beginning"
        }
        stdinP{}
    }
    
    filter{
    }
    
    output{
        elasticsearch{
            hosts => ["172.17.0.1:9200"]
            index => "logstash-%{+YYYY.MM.dd}"
        }
        stdout{
            codec=>rubydebug
        }
    }
    

    启动方式:

    bin/logstash -f /etc/logstash/conf.d/file.conf
    

    kibana

     bin/kibana
