Logstash安装搭建(一)

  Logstash是一个具有实时管道的开源数据收集引擎。可以动态地统一不同来源的数据,并将数据归到不同目的地。也是一个管理事件和日志工具。你可以用它来收集日志,分析它们,并将它们储存起来以供以后使用。

  Logstash 通常都是和 Kibana 以及 Elasticsearch 一起使用,其实还有很多其他的用法值得我们关注的。Elasticsearch的相关配置与搭建可以查看本博客。本文将详细讲述logstash的安装和简单配置。

1、从官网下载Logstash

# wget https://download.elastic.co/logstash/logstash/logstash-2.3.2.tar.gz

2、下载logstash的rpm版本,解压使用官方启动脚本

# wget https://download.elastic.co/logstash/logstash/packages/centos/logstash-2.3.2-1.noarch.rpm

3、Java 8 下载地址:

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html 

4、配置java环境

# tar zxf jdk-8u91-linux-x64.tar.gz -C /usr/local/
# vi /etc/profile
    export JAVA_HOME=/usr/local/jdk1.8.0_91
    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    export PATH=$PATH:$JAVA_HOME/bin
# source /etc/profile

输入 java -version若看到如下信息,则java环境配置成功

java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

5、解压rpm软件包

# mv logstash-2.3.2-1.noarch.rpm /tmp
# cd /tmp/
# rpm2cpio logstash-2.3.2-1.noarch.rpm | cpio -div

6、解压tar包,并配置启动脚本 

# tar zxf logstash-2.3.2.tar.gz -C /usr/local/      
# cd /usr/local/
# mv logstash-2.3.2/ logstash
# groupadd -r logstash  //创建logstash组
# useradd -r -g logstash -d /usr/local/logstash -s /sbin/nologin -c "logstash" logstash  //创建logstash用户

将rpm软件包中的脚本复制到系统指定位置
# cp /tmp/etc/init.d/logstash /etc/init.d/
# cp /tmp/etc/sysconfig/logstash /etc/sysconfig/
# cp /tmp/etc/logrotate.d/logstash /etc/logrotate.d/
# chmod 0644 /etc/logrotate.d/logstash

创建logstash的日志、HOME以及配置文件目录
# mkdir -p /etc/logstash/conf.d/  //配置文件目录
# mkdir /var/log/logstash  //日志目录
# mkdir /var/lib/logstash  //HOME目录
# chown logstash /var/log/logstash
# chown logstash:logstash /var/lib/logstash
# chown -R logstash:logstash /usr/local/logstash/

配置启动脚本中的变量,将其修改为logstash的实际路径
# vi /etc/init.d/logstash
    program=/usr/local/logstash/bin/logstash

此时就可以将自己写好的logstash配置文件放到  /etc/logstash/conf.d/ 下,并设置开机启动。

7、使用简单的配置文件测试

# cat /etc/logstash/conf.d/simple.conf
input {
  stdin {}
}
output {
  stdout {
    codec => rubydebug }
}

使用命令运行logstash

# /usr/local/logstash/bin/logstash -f /etc/logstash/conf.d/simple.conf     // -f 指定配置文件,在启动之前还可以使用 -t 参数指定配置文件检查配置是否正确
Settings: Default pipeline workers: 4
Pipeline main started

输入hello world ,查看输出结果

#/usr/local/logstash/bin/logstash -f /etc/logstash/conf.d/simple.conf 
Settings: Default pipeline workers: 4
Pipeline main started
hello world !
{
       "message" => "hello world !",
      "@version" => "1",
    "@timestamp" => "2016-06-13T02:35:01.737Z",
          "host" => "localhost.localdomain"
}

可以看到,输入什么内容logstash按照某种格式输出,使用CTRL-C命令可以退出之前运行的Logstash。

8、配置logstash使用elasticsearch作为logstash后端

# cat /usr/local/logstash/conf.d/logstash-es-simple.conf
  input {
    stdin {}
  }
  output {
    elasticsearch {
      hosts => "127.0.0.1"}
    stdout {
      codec => rubydebug }
  }

执行命令

 执行命令:
    # /usr/local/logstash/bin/logstash agent -f conf.d/logstash-es-simple.conf
        Settings: Default pipeline workers: 4
        Pipeline main started
        hello logstash
        {
               "message" => "hello logstash",
              "@version" => "1",
            "@timestamp" => "2016-06-13T02:39:25.112Z",
                  "host" => "localhost.localdomain"
        }

使用curl命令发送请求来查看ES是否接收到了数据:

# curl 'http://127.0.0.1:9200/_search?pretty'
        {
          "took" : 21,
          "timed_out" : false,
          "_shards" : {
            "total" : 5,
            "successful" : 5,
            "failed" : 0
          },
          "hits" : {
            "total" : 1,    
            "max_score" : 1.0,
            "hits" : [ {
              "_index" : "logstash-2016.06.13",
              "_type" : "logs",
              "_id" : "AVRg9UHczZ2iuimLmajG",
              "_score" : 1.0,
              "_source" : {
                "message" : "hello logstash",
                "@version" : "1",
                "@timestamp" : "2016-06-13T02:39:25.112Z",
                "host" : "localhost.localdomain"
              }
            } ]
          }
        }

此时已经成功利用elasticsearch和logstash收集数据。
