一、ELK说明
ELK Stack 是 Elasticsearch、Logstash、Kibana 三个开源软件的组合。在实时数据检索和分析场合，三者通常是配合共用，而且又都先后归于 Elastic.co 公司名下，故有此简称。
ELK Stack 在最近两年迅速崛起，成为机器数据分析，或者说实时日志处理领域，开源界的第一选择。和传统的日志处理方案相比，ELK Stack 具有如下几个优点：
处理方式灵活。Elasticsearch 是实时全文索引，不需要像 storm 那样预先编程才能使用；
配置简易上手。Elasticsearch 全部采用 JSON 接口，Logstash 是 Ruby DSL 设计，都是目前业界最通用的配置语法设计；
检索性能高效。虽然每次查询都是实时计算，但是优秀的设计和实现基本可以达到全天数据查询的秒级响应；
集群线性扩展。不管是 Elasticsearch 集群还是 Logstash 集群都是可以线性扩展的；
前端操作炫丽。Kibana 界面上，只需要点击鼠标，就可以完成搜索、聚合功能，生成炫丽的仪表板。
二、架构图
三、规划说明
logstash收集数据:
192.168.1.90(nginx+logstash)
192.168.1.93(nginx+logstash)
redis提供队列:
192.168.1.89(redis)
logstash-server:
192.168.1.87(logstash[server])
elasticsearch集群:
192.168.1.88(elasticsearch)
192.168.1.91(elasticsearch)
192.168.1.92(elasticsearch+kibana)所有服务器时间同步：
# ntpdate 133.100.11.8
软件版本：
jdk-8u91-linux-x64.tar.gz
elasticsearch-2.3.2.rpm
logstash-2.3.2-1.noarch.rpm
kibana-4.5.0-linux-x64.tar.gz
四、安装部署nginx+logstash
192.168.1.90 192.168.1.93
以上两个安装配置一样：
4.1.安装zlib
tar -xf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure
make
make insatll
4.2.安装pcre
tar -xf pcre-8.37.tar.gz

cd pcre-8.37
make
make install
4.3.安装openssl
tar -xf openssl-1.0.2.tar.gz
./config --prefix=/usr/local --openssldir=/usr/local/openssl
make
make insatll
4.4.安装nginx
访问head，查看集群是否一致
tar -xf nginx-1.8.1.tar.gz
./configure --prefix=/app/local/nginx \
--pid-path=/app/local/nginx \
--user=nginx \
--group=nginx \
--with-threads \
--with-file-aio \
--with-http_ssl_module \
--with-pcre=/tmp/soft/pcre-8.37 \
--with-openssl=/tmp/soft/openssl-1.0.2
make
make install
4.5.查看配置文件
vim /app/local/nginx/conf/nginx.conf
user nginx;
worker_processes 1;
error_log logs/error.log notice;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for $request_length $msec $connection_requests $request_time';
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
access_log logs/access.log main;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {

信息查看
1.查看健康信息：
# curl -XGET 'http://192.168.1.88:9200/_cluster/health?pretty'
{
"cluster_name" : "qm.ela.com",
"status" : "green",
"timed_out" : false,
"number_of_nodes" : 3,
"number_of_data_nodes" : 3,
"active_primary_shards" : 14,
"active_shards" : 28,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 0,
"delayed_unassigned_shards" : 0,
"number_of_pending_tasks" : 0,
"number_of_in_flight_fetch" : 0,
"task_max_waiting_in_queue_millis" : 0,
"active_shards_percent_as_number" : 100.0
}
2.查看节点数：
# curl -XGET '192.168.1.88:9200/_cat/nodes?v'
host ip heap.percent ram.percent load node.role master name
192.168.1.91 192.168.1.91 10 87 0.00 d m n2.qm.com
192.168.1.92 192.168.1.92 7 93 0.00 d m n3.qm.com
192.168.1.88 192.168.1.88 17 88 0.00 d * n1.qm.com
由此可见，192.168.1.88已经成为主节点
3.查看节点分片信息：
# curl -XGET '192.168.1.88:9200/_cat/indices?v'
