关于 elk 不用说，大家多多少少都听过，最近我搭建了一套用作收集日志，供大家参考：
一. 安装 elasticsearch,logstash,kibana
强烈建议安装去 es 的官网安装：今天是 2019.4.9，目前最新的版本是 6.7.1，三个都装 6.7.1 版本 (版本最好一致，否则会有各种疑难杂症)elasticsearch: https://www.elastic.co/downlo…logstash: https://www.elastic.co/cn/dow…kibana:https://www.elastic.co/cn/dow…
其中 es 的安装教程我在这篇文章里面已经写了：https://segmentfault.com/a/11…，下面介绍 logstash 和 kibana 的安装过程
1.logstash: 下载后
## 进入安装包所在目录，解压
tar -xf logstash-6.7.1.tar.gz
## 切换到 bin 目录
cd /logstash-6.7.1/bin
## 编辑或者创建一个启动的配置文件，到时候用这个配置文件启动
vim input_flter_output.conf
input {
file{
path=> “/crawler/jenkins/*.log” ## 生成日志的目录
type=> “cml” ## 索引的类型
start_position=> “beginning” ## 一开始就输入原来的日志信息
}
stdin{}
}
filter{
}
output{
elasticsearch{
action=> “index”
hosts=> “www.iamcrawler.cn:9500” ## 输出到 elasticsearch 上面
index=> “log-%{+yyyy.MM.dd}” ## 生成一个 log- 时间的索引
}
}
#最后保存退出
## 在 bin 目录下再编写一个启动 bat
vim run.bat
sh logstash -f input_flter_output.conf &
#最后保存退出
然后运行 run.bat 即可
[root@iamcrawler bin]# sh run.bat
## 正常会出现以下情况：
[root@iamcrawler bin]# Sending Logstash logs to /crawler/logstash/logstash-6.7.1/logs which is now configured via log4j2.properties

2.kibana 的安装 kibana 安装比较简单，下载后，进入安装目录的 config 目录，如：cd /crawler/kibana/kibana-6.7.1-linux-x86_64/config
vim kibana.yml
## 添加如下命令
server.host: 0.0.0.0
elasticsearch.url: “http://localhost:9500” #这里是 es 的 http 地址
## 进入 kibana 目录，执行以下命令，后台运行 kibana
./bin/kibana &
二.kibana 的使用可以参照网上的很多教程，这里就不过多的描述了
