一，文件说明
- centos7
- jdk-8u112-linux-x64.tar.gz
- elasticsearch-5.1.1.tar.gz
- filebeat-5.1.1-x86_64.rpm
- kibana-5.1.1-linux-x86_64.tar.gz
- logstash-5.1.1.tar.gz
- redis-3.2.6.tar.gz
二，环境配置
elk5.1之后需要jdk1.8以上的支持，所以需要配置jdk环境变量
1 用java -version命令查看centos是否自带openJDK 如果自带则卸载，卸载命令如下：
rpm -e --nodeps 'rpm -qa | grep java'
2 解压,重命名jdk到 /usr/local/java目录 并记录了jdk根目录
# tar -zxf jdk-8u112-linux-x64.tar.gz
# mv jdk1.8.0_112/ jdk1.8/
# pwd
/usr/local/java/jdk1.8
3 配置java环境变量
# vi /etc/profile
加入如下内容:
export NODE_HOME=/opt/soft/node
export PATH=$NODE_HOME/bin:$PATH # 这是node.js的环境变量
export JAVA_HOME=/usr/local/java/jdk1.8
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
# source /etc/profile
# java -version
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)
三 解压并授权elk文件
# tar -zxf elasticsearch-5.1.1.tar.gz
# tar -zxf kibana-5.1.1-linux-x86_64.tar.gz
# tar -zxf logstash-5.1.1.tar.gz
# chmod -R 777 elasticsearch-5.1.1
# chmod -R 777 kibana-5.1.1-linux-x86_64
# chmod -R 777 logstash-5.1.1
四 新建centos系统用户并授予root权限,防火墙关闭
# useradd elkuser
# passwd elkuser
授予root权限
# vi /etc/sudoers 在root ALL=(ALL) ALL后添加
elkuser ALL=(ALL) ALL
注意:强行写入用 wq!
# source /etc/sudoers 使文件生效
关闭防火墙
查看状态
# firewall-cmd --state
# service iptables status
centos7 如果没有安装iptables-services 那么第二条命令不生效
如果是运行状态则关闭(关闭方式请自行百度)
五 安装配置filebeat
进入filebeat文件目录,如果不成功,则去掉sudo
sudo rpm -vi filebeat-5.1.2-x86_64.rpm
查看filebeat安装位置 rpm -ql filebeat
配置filebeat
###################### Filebeat Configuration Example #########################
#=========================== Filebeat prospectors =============================
filebeat.prospectors:
- input_type: log
# Paths that should be crawled and fetched. Glob based paths.
paths:
- /var/elklog/Linux/*.log
document_type: linux
- input_type: log
paths:
- /var/elklog/openstackMitakaLog/*.log
document_type: api
#================================ Outputs =============================
#----------------------------- Logstash output --------------------------------
output.logstash:
# The Logstash hosts
hosts: ["192.168.1.19:5043"]
启动filbeat
sudo /etc/init.d/filebeat start
或 /etc/init.d/filebeat start
结果:Starting filebeat: 2017/01/16 11:19:40.838639 beat.go:267: INFO Home path: [/usr/share/filebeat] Config path: [/etc/filebeat] Data path: [/var/lib/filebeat] Logs path: [/var/log/filebeat]

Config OK [确定]
六 配置运行elasticsearch
配置es(都以此为简称) 没配置的即为默认配置
# ======================== Elasticsearch Configuration =========================
# ---------------------------------- Cluster -----------------------------------
cluster.name: bjhit-cluster
# ------------------------------------ Node ------------------------------------
node.name: node-bjhit
# ---------------------------------- Network -----------------------------------
network.host: 192.168.1.19
http.port: 9200
运行es： 进入elasticsearch解压文件目录
es不能用root用户启动,只能用我们刚刚建立的elkuser来启动否则或报错
./bin/elasticsearch
七 安装运行redis
安装redis需要依赖gcc 所以先确定gcc安装了 如果没有则请安装;确认安装命令如下:
确认：gcc -v
安装：yum install -y gcc g++ gcc-c++ make
完成gcc安装后:
$ tar xzf redis-3.2.6.tar.gz
$ cd redis-3.2.6
$ make
启动测试redis
$ src/redis-server
另开窗口测试
$ src/redis-cli
redis> set foo bar
OK
redis> get foo
"bar"
测试成功后,启动redis 如果redis安装在另一个linux下的话则运行:
./src/redis-server --protected-mode no 否则直接运行./src/redis-server
八 安装logstash插件以及配置启动logstash
filebeat和logstash之间必须要在logstash目录下安装一个插件:
进入logstash目录后执行： ./bin/logstash-plugin install logstash-input-beats
安装过程可能不成功，那就坚持不懈再次安装，最后会成功的；以下是成功报文：
Validating logstash-input-beats
Installing logstash-input-beats
WARNING: SSLSocket#session= is not supported
Installation successful
配置logstash 新建且配置完后放到logstash的bin目录:
1,redis-input.conf
#input { stdin { } }
#input {
# file {
# path => ["/var/elklog/*.log"]
# type => "system"
# start_position => "beginning"
# }
#}
input {
beats {
port => "5043"
}
}
# The filter part of this file is commented out to indicate that it is
# optional.
# filter {
#
# }
output {
# elasticsearch {
# hosts => [ "192.168.1.19:9200" ]
# index => "logstash-%{type}-%{+YYYY.MM.dd}"
# document_type => "%{type}"
# flush_size => 20000
# idle_flush_time => 10
# template_overwrite => true
# }
redis {
host => "192.168.1.211"
port => 6379
data_type => "list"
key => "logstash:redis"
}
stdout { codec => rubydebug }
}
2,redis-output.conf
#input { stdin { } }
#input {
# file {
# path => ["/var/elklog/*.log"]
# type => "system"
# start_position => "beginning"
# }
#}
#input {
# beats {
# port => "5043"
# }
#}
# The filter part of this file is commented out to indicate that it is
# optional.
# filter {
#
# }
input {
redis {
data_type => "list"
key => "logstash:redis"
host => "192.168.1.211"
port => 6379
}
}
output {
if[type] =="linux"{
elasticsearch {
hosts => [ "192.168.1.19:9200" ]
index => "linux-%{+YYYY.MM.dd}"
document_type => "%{[@metadata][type]}"
flush_size => 20000
idle_flush_time => 10
template_overwrite => true
}
}else if[type] =="api"{
elasticsearch {
hosts => [ "192.168.1.19:9200" ]
index => "api-%{+YYYY.MM.dd}"
document_type => "%{[@metadata][type]}"
flush_size => 20000
idle_flush_time => 10
template_overwrite => true
}
}
stdout { codec => rubydebug }
}
启动logstash
分别用如下参数启动
./logstash -f redis-output.conf
./logstash -f redis-input.conf
九配置启动kibana
配置kibana
server.port: 5601
server.host: "192.168.1.19"
server.name: "localhost"
elasticsearch.url: "http://192.168.1.19:9200"
启动kibana
进入kibana目录(我测试的时候elk都是用的elkuser用户来运行)
./bin/kibana
