• ELK7.x环境部署


    1、Elasticsearch (ES)配置:
    部署配置ES,需要配置JDK环境,JDK是Java语言的软件开发工具包:
    下载JAVA jdk源码包:
    wget https://mirrors.yangxingzhen.com/jdk/jdk-11.0.1_linux-x64_bin.tar.gz
    tar xf jdk11.0.1_linux-x64_bin.tar.gz
    mv jdk11.0.1_linux-64_bin /usr/java

    设置环境变量:

    cat >>/etc/profile<<EOF
    export JAVA_HOME=/usr/java
    export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
    EOF
    
    source /etc/profile
    java -version

    ELK环境信息:

    192.168.1.11            Elasticsearch
    192.168.1.12            kibana
    192.168.1.13            logstash
    1) 配置ES
    下载elasticsearch7.5.1版本:
    wget http://mirrors.cnbugs.com/LINUX/elasticsearch/elasticsearch-7.5.1-linux-x86_64.tar.gz
    tar xf elasticsearch-7.5.1-linux-x86_64.tar.gz
    mv elasticsearch-7.5.1 /usr/local/elasticsearch
    修改 /usr/local/elasticsearch/config/elasticsearch.yml文件,设置监听端口地址为:0.0.0.0

    创建elk用户, 用来启动ES,ES服务默认不允许使用root启动服务:

    useradd elk
    chown -R elk. /usr/local/elasticsearch
    su - elk
    /usr/local/elasticsearch/bin/elasticsearch -d
    查看日志及监听端口:
    tailf /usr/local/elasticsearch/logs/elasticsearch.log
    ps -ef|grep java
    netstat -nutlp|grep -E "9200|9300"

    报错问题汇总:
    1、ERROR: [2] bootstrap checks failed
    [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
    解决方法:vim /etc/security/limits.conf (添加如下两行)
    * soft nofile 65536
    * hard nofile 65536 
    * soft nproc 5000
    * hard nproc 5000
    root soft nproc 5000
    root hard nproc 5000
    2、ERROR: [1] bootstrap checks failed
    [1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
    解决方法: vim //usr/local/elasticsearch/config/elasticsearch.yml
    # 在第23行位置去掉注释,起个名字,默认是node-1
    node.name: node-1
    3、ERROR: [1] bootstrap checks failed
    [1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
    解决方法:vim /usr/local/elasticsearch/config/elasticsearch.yml
     # 在第72行位置去掉注释,修改为只保留一个node-1,名称要和node.name的名字保持一致 
     cluster.initial_master_nodes: ["node-1"]
    3、ERROR: [1] max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
    解决方法:vim /etc/sysctl.conf 添加如下一行代码: sysctl -p 生效
    vm.max_map_count=262144
    2、kibana WEB 配置:
    下载kibana:
    wget https://mirrors.yangxingzhen.com/kibana/kibana-7.5.1-linux-x86_64.tar.gz
    部署安装kibana 不需要安装Java jdk环境,下载源码包,解压启动即可:
    tar xf kibana-7.5.1-linux-x86_64.tar.gz
    mv kibana-7.5.1-linux-x86_64 /usr/local/kibana
    修改kibana配置文件信息(监听端口和IP地址),设置ES地址:
    vim /usr/local/kibana/config/kibana.yml

    启动服务:
    /usr/local/kibana/bin/kibana
    ps -ef|grep node
    netstat -nutlp|grep 5601
    浏览器访问:192.168.1.12:5601

    设置后台启动:
    nohup /usr/local/kibana/bin/kibana &
    4、ELK7.5.1修改为中文版:
    修改kibana配置文件:
    [elk@kibana ~]$ vim /usr/local/kibana/config/kibana.yml 
    #最后一行配置信息
    i18n.locale: "zh-CN"
    重启kibana:
    nohup /usr/local/kibana/bin/kibana >&1 &

    5、logstash 配置:
    由于logstash基于JAVA 语言开发,logstash客户端部署需要安装JDK环境:
    wget https://mirrors.yangxingzhen.com/jdk/jdk-11.0.1_linux-x64_bin.tar.gz
    tar xf jdk11.0.1_linux-x64_bin.tar.gz
    mv jdk11.0.1_linux-64_bin /usr/java
    设置环境变量:
    
    cat >>/etc/profile<<EOF
    export JAVA_HOME=/usr/java
    export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
    EOF
    
    source /etc/profile
    java -version
    下载logstash软件包:
    wget https://mirrors.yangxingzhen.com/logstash/logstash-7.5.1.tar.gz
    tar xf logstash-7.5.1.tar.gz
    mv logstash-7.5.1 /usr/local/logstash
    ELK收集系统日志:
    创建收集日志配置目录及文件:
    mkdir  -p  /usr/local/logstash/config/etc/
    cd /usr/local/logstash/config/etc/
    touch index.conf
    index.conf内容如下:
    input {
      stdin { }
     }
     output {
      stdout {
      codec => rubydebug {}
     }
      elasticsearch {
      hosts => "192.168.1.11:9200" }
     }
    启动index.conf服务:
    /usr/local/logstash/bin/logstash -f index.conf
     
    浏览器访问:192.168.1.12:5601
