一、概念介绍
Elasticsearch
ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎，基于RESTful web接口。Elasticsearch是用Java开发的，并作为Apache许可条款下的开放源码发布，是第二流行的企业搜索引擎。设计用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便。 在elasticsearch中，所有节点的数据是均等的。
Logstash
Logstash是一个完全开源的工具，他可以对你的日志进行收集、分析，并将其存储供以后使用（如，搜索），您可以使用它。说到搜索，logstash带有一个web界面，搜索和展示所有日志。
Kibana
Kibana是一个基于浏览器页面的Elasticsearch前端展示工具。Kibana全部使用HTML语言和Javascript编写的。
Grafana
Grafana是 Graphite 和 InfluxDB 仪表盘和图形编辑器。Grafana 是开源的，功能齐全的度量仪表盘和图形编辑器，支持 Graphite，InfluxDB 和 OpenTSDB。Grafana 主要特性：灵活丰富的图形化选项；可以混合多种风格；支持白天和夜间模式；多个数据源；Graphite 和 InfluxDB 查询编辑器等等。

三、软件安装及配置
1、nginx安装及配置
分别在三台服务安装：
172.16.8.201 nginx+logstash
172.16.8.202 nginx+logstash
172.16.8.203 nginx+logstash
1.1使用yum源安装nginx
yum install nginx -y
1.2查看安装版本信息：
rpm -qa nginx
nginx-1.10.2-1.el6.x86_64
1.3查看所有的配置文件
rpm -qc nginx
/etc/logrotate.d/nginx
/etc/nginx/conf.d/default.conf
/etc/nginx/conf.d/ssl.conf
/etc/nginx/conf.d/virtual.conf
/etc/nginx/fastcgi.conf
/etc/nginx/fastcgi.conf.default
/etc/nginx/fastcgi_params
/etc/nginx/fastcgi_params.default
/etc/nginx/koi-utf
/etc/nginx/koi-win
/etc/nginx/mime.types
/etc/nginx/mime.types.default
/etc/nginx/nginx.conf
/etc/nginx/nginx.conf.default
/etc/nginx/scgi_params
/etc/nginx/scgi_params.default
/etc/nginx/uwsgi_params
/etc/nginx/uwsgi_params.default
/etc/nginx/win-utf
/etc/sysconfig/nginx
修改nginx的配置文件
vim /etc/nginx/nginx.conf
##### http 标签中
log_format json '{"@timestamp":"$time_iso8601",'
'"@version":"1",'
'"client":"$remote_addr",'
'"url":"$uri",'
'"status":"$status",'
'"domain":"$host",'
'"host":"$server_addr",'
'"size":$body_bytes_sent,'
'"responsetime":$request_time,'
'"referer": "$http_referer",'
'"ua": "$http_user_agent"'
'}';
access_log /var/log/nginx/access_json.log json;
1.4设置开机启动
chkconfig nginx on
/etc/init.d/nginx start
-----------------------------------------------------------------------
访问nginx页面
http://172.16.8.201/
AB压测工具
yum install httpd-tools -y
ab -n10000 -c1 http://172.16.8.201/
-----------------------------------------------------------------------
2、安装及配置logstash
2.1安装完java后，检测
yum install -y java
java -version
java version "1.7.0_99"
OpenJDK Runtime Environment (rhel-2.6.5.1.el6-x86_64 u99-b00)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
2.3安装logstash
rpm -ivh logstash-2.4.0.noarch.rpm
2.4基本的输入输出
/opt/logstash/bin/logstash -e 'input { stdin{} } output { stdout{} }'
Settings: Default pipeline workers: 1
Pipeline main started
e^Hhehe
2017-02-25T07:00:46.494Z ops-nginx01 hehe
test
\2017-02-25T07:00:57.475Z ops-nginx01 test
test
2017-02-25T07:01:02.499Z ops-nginx01 \test
2.5使用rubydebug详细输出
/opt/logstash/bin/logstash -e 'input { stdin{} } output { stdout{ codec => rubydebug} }'
Settings: Default pipeline workers: 1
Pipeline main started
hehe2017 # 输入 hehe2017
{
{
"message" => "hehe2017", # 输入的信息
"@version" => "1", # 版本
"@timestamp" => "2017-02-25T07:03:06.332Z", # 时间
"host" => "ops-nginx01" # 存放的主机节点
}
2.6检测语法是否有错
/opt/logstash/bin/logstash -f json.conf --configtest
Configuration OK
json格式显示内容
[root@ops-nginx01 conf.d]# /opt/logstash/bin/logstash -f json.conf
Settings: Default pipeline workers: 1
Pipeline main started
{
"@timestamp" => "2017-02-25T10:37:42.000Z",
"@version" => "1",
"client" => "172.16.8.4",
"url" => "/index.html",
"status" => "200",
"domain" => "172.16.8.201",
"host" => "172.16.8.201",
"size" => 3698,
"responsetime" => 0.0,
"referer" => "-",
"ua" => "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0",
"path" => "/var/log/nginx/access.log"
}
{
"@timestamp" => "2017-02-25T10:37:42.000Z",
"@version" => "1",
"client" => "172.16.8.4",
"url" => "/nginx-logo.png",
"status" => "200",
"domain" => "172.16.8.201",
"host" => "172.16.8.201",
"size" => 368,
"responsetime" => 0.0,
"referer" => "http://172.16.8.201/",
"ua" => "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0",
"path" => "/var/log/nginx/access.log"
}
2.7修改配置文件，将数据输出到redis：
cat logstash.conf
input {
file {
path => ["/var/log/nginx/access.log"]
type => "nginx_log"
start_position => "beginning"
}
}
output {
redis {
host => "172.16.8.204"
key => 'logstash-redis'
data_type => 'list'
}
}
3、redis安装及配置
3.1安装所需包
yum install wget gcc gcc-c++ -y
3.2下载软件包
wget http://download.redis.io/releases/redis-3.0.7.tar.gz

cp mkrelease.sh /usr/local/redis/bin/
cd ../src
cp redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server redis-trib.rb /usr/local/redis/bin/
创建数据存放目录
mkdir -pv /data/redis/db
mkdir -pv /data/log/redis
dir ./ 修改为dir /data/redis/db/
vim +192 redis.conf

3.4启动redis服务
nohup /usr/local/redis/bin/redis-server /usr/local/redis/conf/redis.conf &
3.5查看redis进程是否存在
ps -ef | grep redis
root 5000 1611 0 14:42 pts/0 00:00:00 /usr/local/redis/bin/redis-server *:6379
root 5004 1611 0 14:42 pts/0 00:00:00 grep redis
3.6查看redis默认6379端口
netstat -tnlp
Active Internet connections (only servers)
