标签:日志系统   elk   

安装elk    
    安装Java 1.8环境
        解压源码安装包:

        tar xf jdk-8u121-linux-x64.tar.gz 
        ll
        mkdir /work/opt -p
        mv  jdk1.8.0_121  /work/opt/jdk
        ll /work/opt/jdk/
        chown -R root.root  /work/opt
         
        vim /etc/profile :    //添加
        export JAVA_HOME=/work/opt/jdk
        export JAVA_BIN=$JAVA_HOME/bin
        export JRE_HOME=${JAVA_HOME}/jre
        export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar
        export PATH=$JAVA_BIN:$PATH

        
    安装 elasticsearch-5.3.0

    tar xf elasticsearch-5.3.0.tar.gz 
    mv elasticsearch-5.3.0 /work/opt/elasticsearch
    
    
    ubuntu@ip-172-31-1-79:/work/opt/elasticsearch/config$ egrep -v ‘#|^$‘ elasticsearch.yml
    cluster.name: lvnian-elk
    node.name: lvnian-elk-node1
    path.data: /data  #由于是普通用户启动elasticsearch,所以这个目录的属主需要改为普通用户
    path.logs: /work/opt/elasticsearch/logs     #由于是普通用户启动elasticsearch,所以这个目录的属主需要改为普通用户
    bootstrap.memory_lock: false
    network.host: 0.0.0.0
    http.port: 9200
    http.cors.enabled: true 
    http.cors.allow-origin: "*" 
    ubuntu@ip-172-31-1-79:/work/opt/elasticsearch/config$ 
    nohup /work/opt/elasticsearch/bin/elasticsearch >> /tmp/elasticsearch.log  &

   ##ES 5.1.1 安装 head:
    (5.1.1版本的 elasticsearch 没有提供直接插件安装方法,但在该github上该插件作者给出了方法)

        下载二进制源码包:
        wget https://nodejs.org/dist/v4.2.2/node-v6.2.0-linux-x64.tar.gz
        解压:
        tar xf node-v6.2.0-linux-x64.tar.gz -C /work/opt/
        设置环境变量:
        vim /etc/profile: 
            export NODE_HOME=/work/opt/node/
            export PATH=$PATH:$NODE_HOME/bin
         
        root@ip-172-31-1-79:/work/source# node --version
        v6.10.1
    
        npm config set registry https://registry.npm.taobao.org    //设置代理镜像源,加速下载
        cd /home/stt/node-v4.2.2-linux-x64/lib/node_modules
        npm install grunt    //显示的2条warn可以忽略

        测试grunt是否生效:

        $ grunt -version
        grunt-cli v1.2.0
        grunt v1.0.1

        安装head插件:

          下载:git clone git://github.com/mobz/elasticsearch-head.git
        cd /home/stt/elasticsearch-head
        npm install (提示:如果遇到网络的瓶颈,将预先下载的源码包放在对应的位置效果一样,目录为/tmp/phantomjs/,确定位置后可自行创建并上传包)
        修改 elasticsearch-head/ _site/app.js
        // 把localhost改为ip
        找到:
        this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";
        改为:
        this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://192.168.8.116:9200";
        修改 elasticsearch-head/Gruntfile.js
        connect: {
            server: {
                options: {
                    hostname: "0.0.0.0",     //增加这个配置
                    port: 9100,
                    base: ‘.‘,
                    keepalive: true
                }
            }
        }

        启动服务:(后台运行)
        grunt server &    //需要在 /home/stt/elasticsearch-head 下执行,因为我的 grunt 没有进行全局的安装


        
    ##安装Logstash(这个软件在你需要读取的日志服务上安装,用logstash读取你的日志,上传给elasticsearch的):
        也需要安装java1.8环境

        tar xf logstash-5.3.0.tar.gz 
        mkdir /work/opt
        mv logstash-5.3.0 /work/opt/
        cd /work/opt/

    vim /work/opt/logstash-5.3.0/conf/central.conf    #(处理基于 FILE 方式输入的日志信息,这里是简单的举个例子,日后继续学习补充)

        input {
            file {
                path => "/tmp/*.log"
            }
        }
        output {
            elasticsearch {
                hosts => "192.168.8.116:9200"
                index => "nginx-access"
            }
            stdout {
                codec => rubydebug
            }
        }

    
    
    
    ##安装Kibana:
    解压源码包:

    tar zxf kibana-5.1.1-linux-x86_64.tar.gz -C /home/stt/server/
    vim config/kibana.yml    //修改
        server.port: 5601    //打开注释而已,不用可以去效果,请使用默认端口
        server.host: "0.0.0.0"    //打开监听地址,让别的机器也能访问这个 kibana
        elasticsearch.url: "http://127.0.0.1:9200"      //这个url要根据实质情况,添加访问 elasticsearch 的url
    启动服务: (后台运行)
    /home/stt/server/kibana-5.1.1-linux-x86_64/bin/kibana &

        
    安装nginx 反向代理,
    apt-gei install nginx


    nginx放心代理配置文件如下:

 ##文件名kibana.conf
    upstream backend {
                 server 172.31.6.155:5601;
             }
      server {
            listen       80;
            server_name  kibana.lvnian.co;
        access_log /tmp/kibana-access.log;
        error_log /tmp/kibana-error.log;
            location / {
                #设置主机头和客户端真实地址,以便服务器获取客户端真实IP
                 proxy_set_header Host $host;
                 proxy_set_header X-Real-IP $remote_addr;
                 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                 #禁用缓存
                 proxy_buffering off;
                 #反向代理的地址
                 proxy_pass http://backend;     
            }
        }


        
        
        
    logstash 读取nginx的访问日志以及error日志,上传到logstash的配置文件文件。

   用下面命令运行即可

nohup /work/opt/logstash-5.3.0/bin/logstash -f /work/opt/logstash-5.3.0/conf/elk-nginx-log.conf &

   文件名: elk-nginx-log.conf
    input {

            start_position => beginning
        }
