简单来讲他具体的工作流程就是 logstash agent 监控并过滤日志，将过滤后的日志内容发给redis(这里的redis只处理队列不做存储)，logstash index将日志收集在一起交给全文搜索服务ElasticSearch 可以用ElasticSearch进行自定义搜索 通过Kibana 来结合 自定义搜索进行页面展示
kibana 页面展示
首先到 logstash index服务器上面，logstash分为 index和aget ，agent负责监控、过滤日志，index负责收集日志并将日志交给ElasticSearch 做搜索此外 logstash 的收集方式分为 standalone 和 centralized。
standalone 是所有功能都在一个服务器上面，自发自收，centralized 就是集中收集，一台服务器接收所有shipper(个人理解就是logstash agent)的日志。
其实 logstash本身不分 什么 shipper 和 collector ，只不过就是配置文件不同而已，我们这次按照集中的方式来测试
这里有两台服务器
192.168.124.128 logstash index,ElasticSearch,kibana,JDK
192.168.124.132 logstash agent,redis,JDK
准备工作
安装：openssl
卸载旧版本
apt-get remove openssl apt-get autoremove openssl
下载最新版本
wget http://www.openssl.org/source/openssl-1.0.1i.tar.gz
tar -zxvf openssl-1.0.1i.tar.gz cd /opt/openssl-1.0.1i ./config --prefix=/usr/local/ssl make & make install
建立软连接
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl ln -s /usr/local/ssl/include/openssl /usr/include/openssl
刷新动态配置
vim /etc/ld.so.conf
在文末插入一行
/usr/local/ssl/lib ldconfig -v
测试
openssl version -a
安装PCRE库
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.33.tar.gz
tar -zxvf pcre-8.33.tar.gz cd pcre-8.33 ./configure --prefix=/usr/local/pcre-8.33 make & make install
安装zlib
wget http://zlib.net/zlib-1.2.8.tar.gz
tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8 ./configure --prefix=/usr/local/zlib-1.2.8 make & make install
安装nginx
wget http://nginx.org/download/nginx-1.6.1.tar.gz
tar -zxvf nginx-1.6.1.tar.gz cd nginx-1.6.1 ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-openssl=/opt/openssl-1.0.1i --with-pcre=/opt/pcre-8.33 --with-zlib=/opt/zlib-1.2.8
nginx 命令
启动：/usr/local/nginx/sbin/nginx 重启：/usr/local/nginx/sbin/nginx –s reload 停止：/usr/local/nginx/sbin/nginx -s stop 查看主进程：netstat -ntlp 检查是否启动成功：netstat -ano|grep 80
安装ruby 运行Kibana 必须
sudo apt-get update wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.gz ./configure --prefix=/usr/local/ruby make && make install
环境设置
vi /etc/environment
将Ruby的路径加入环境变量 中并保存/etc/environment，如下面内容：
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/ruby/bin"
修改了环境变量文件后，需要通过source命令让修改马上生效，命令如下：
$ source /etc/environment
为了检查安装是否成功，可以输入下面的命令进行测试 ：
$ruby –v
确认安装成功后通过一下命令添加命令链接，目前我也不清楚创建这些链接的目的是什么，按照Ruby“约定大于配置”的原则，应该是一种约定。(keyboardota)
$ sudo ln -s /usr/local/ruby/bin/ruby /usr/local/bin/ruby $ sudo ln -s /usr/local/ruby/bin/gem /usr/bin/gem
或者：
apt-get install ruby-full
安装rubygems ruby扩展必须
wget http://production.cf.rubygems.org/rubygems/rubygems-2.4.1.tgz
tar -zxvf rubygems-2.4.1.tgz cd rubygems-2.4.1 ruby setup.rb
安装redis 用来处理日志队列
wget http://download.redis.io/releases/redis-2.8.13.tar.gz
tar -zxvf redis-2.8.13.tar.gz cd redis-2.8.13 make vim redis.conf 设置 "daemonize yes" 启动：/usr/local/redis-2.8.13/src/redis-server /usr/local/redis-2.8.13/redis.conf
安装 elasticsearch 全文搜索服务(logstash集成了一个)
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.3.2.tar.gz
tar -zxvf elasticsearch-1.3.2.tar.gz cd elasticsearch-1.3.2 启动：
/usr/local/elasticsearch-1.3.2/bin/elasticsearch -d 访问
http://localhost:9200
安装：logstash 收集、过滤日志
wget https://download.elasticsearch.org/logstash/logstash/logstash-1.4.2.tar.gz
tar -zxvf logstash-1.4.2.tar.gz
启动
nohup /usr/local/logstash-1.4.2/bin/logstash -f /usr/local/logstash-1.4.2/agent.conf &
nohup /usr/local/logstash-1.4.2/bin/logstash -f /usr/local/logstash-1.4.2/indexer.conf &
vim /usr/local/logstash-1.4.2/agent.conf
input {
file {
path => [ "/var/log/*.log", "/var/log/messages", "/var/log/syslog", "/var/log/denyhosts", "/var/log/dmesg", "/var/log/faillog", "/var/log/aptitude" ]
start_position => beginning
}
file {
type => "nginx-access"
path => "/var/log/nginx/access.log"
}
}
output {
redis{
host =>"192.168.124.128"
data_type => "list"
key => "logstash"
}
}
vim /usr/local/logstash-1.4.2/indexer.conf
input {
redis {
host => "192.168.124.128"
data_type => "list"
key => "logstash"
}
}
output {
elasticsearch {
host => "192.168.124.132" #指定elasticsearch服务位置
}
}
安装Kibana
wget https://download.elasticsearch.org/kibana/kibana/kibana-3.1.0.tar.gz
tar -zxvf kibana-3.1.0.tar.gz vim /usr/local/kibana-3.1.0/config.js
搜索"elasticsearch"参数，并对其进行修改以适应您的环境：
elasticsearch: "http://192.168.124.132:9200",
您还可以修改default_route参数，默认打开logstash仪表板而不是Kibana欢迎页面：
default_route : ‘/dashboard/file/logstash.json‘,
下载配置模板
wget https://raw.github.com/elasticsearch/kibana/master/sample/nginx.conf
修改Nginx配置
vim /usr/local/nginx/conf/nginx.conf
增加Server节点
#
# Nginx proxy for Elasticsearch + Kibana
#
# In this setup, we are password protecting the saving of dashboards. You may
# wish to extend the password protection to all paths.
#
# Even though these paths are being called as the result of an ajax request, the
# browser will prompt for a username/password on the first request
#
# If you use this, you‘ll want to point config.js at http://FQDN:80/ instead of
# http://FQDN:9200
#
server {
listen *:80 ;

如果有防火墙需要放开这些端口：
