开机启动命令（这里作说明，先不用操作）

# vim /etc/rc.local  //需创建elasticsearch、kibana用户，并修改相应目录权限；logstash因为要发邮件，所以用root用户身份运行

su -l -c "su elasticsearch /opt/elasticsearch/bin/elasticsearch >/dev/null 2>&1 &"
su -l -c "su kibana /opt/kibana/bin/kibana >/dev/null 2>&1 &"
su -l -c "nohup /opt/logstash/bin/logstash -f /opt/logstash/config/log_indexer_tomcat_catalina_local_250.conf >/dev/null 2>&1 &"

二、Software Installation

2.1.Server Software Installation

2.1.1 Install JDK
# tar xf jdk-7u79-linux-x64.tar.gz -C /opt/  //解压JDK至指定目录
# ln -sv /opt/jdk1.7.0_79/ /opt/java  //创建链接，保留原来目录可以方便一目了然的看到版本号
# vim /etc/profile.d/java.sh  //创建环境变量

export JAVA_HOME=/opt/java
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

# . /etc/profile.d/java.sh  //使环境变量生效
# java -version  // 查看是否生效，生效了会显示java版本信息

java version "1.7.0_79" Java(TM) SE Runtime Environment (build 1.7.0_79-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

2.1.2 Install Elasticsearch
# groupadd -g 92 elasticsearch
# useradd -g 92 -u 92 elasticsearch
# tar xf elasticsearch-2.3.1.tar.gz -C /opt/  //解压elasticsearch至指定目录
# ln -sv /opt/elasticsearch-2.3.1/bin/elasticsearch /usr/bin/  //将elasticsearch可执行文件链接至/usr/bin目录，方便在任何目录下都可直接执行`elasticsearch`
# chown -R elasticsearch.elasticsearch /opt/elasticsearch/
2.1.3 Install Logstash
# tar xf logstash-2.3.1.tar.gz -C /opt/  //解压logstash至指定目录
# ln -sv /opt/logstash-2.3.1/bin/logstash /usr/bin/  //将logstash可执行文件链接至/usr/bin目录，方便在任何目录下都可直接执行`logstash`
2.1.4 Install Redis
# tar xf redis-3.0.7.tar.gz  //解压至当前目录
# cd redis-3.0.7  //切换至redis源码目录
# make  //编译
# yum install tcl  //安装测试依赖工具
# make test  //有可能会失败，只是看看，不用在意
# make install  //安装
# mkdir /opt/redis/{db,conf} -pv  //创建redis安装目录
# cp redis.conf /opt/redis/conf/  //复制配置文件至redis安装目录
# cd src
# cp redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server mkreleasehdr.sh /opt/redis/  //复制各文件至redis安装目录
# ln -sv /opt/redis/redis-cli /usr/bin/  //将redis-cli可执行文件链接至/usr/bin目录，方便在任何目录下都可直接执行`redis-cli`
# vim /opt/redis/conf/redis.conf  //修改redis.conf 中的 `daemonize`为`yes`,让server以守护进程在后台执行，这一步可以不做，因为后面要执行的脚本会自动创建这个文件，且这个值会设置为`yes`

daemonize yes

make install仅仅在你的系统上安装了二进制文件，不会替你默认配置init脚本和配置文件，为了把它用在生产环境而安装它，在源码目录的utils目录下Redis为系统提供了
这样的一个脚本install_server.sh

#　./utils/install_server.sh  //执行sh格式的安装脚本

三、Start Service

服务端

3.1 Start Redis

# /etc/init.d/redis_6379 start
# netstat -tnlp  //查看是否有6379端口

3.2 Start Elasticsearch

elasticsearch只能以普通用户运行

# nohup elasticsearch >nohup &  //启动并放至后台运行
# vim /etc/rc.local  //设置开机启动

su -l -c "su elasticsearch /opt/elasticsearch/bin/elasticsearch >/dev/null 2>&1 &"

# netstat -tnlp  //ElasticSearch默认的对外服务的HTTP端口是9200，节点间交互的TCP端口是9300，注意打开tcp端口
# exit  //退出当前用户

http://10.66.3.155:9200 //可以看到如下信息

{ "name" : "node0", "cluster_name" : "es_cluster", "version" : { "number" : "2.3.1", "build_hash" : "bd980929010aef404e7cb0843e61d0665269fc39", "build_timestamp" : "2016-04-04T12:25:05Z", "build_snapshot" : false, "lucene_version" : "5.5.0" }, "tagline" : "You Know, for Search" }

# curl -X GET http://10.66.3.155:9200  //获取网页内容
# curl -I GET http://10.66.3.155:9200  //获取网页头部信息,200正常

3.3 Start Kibana

# nohup kibana >nohup &  //启动并放至后台运行
# vim /etc/rc.local  //设置开机启动

su -l -c "su kibana /opt/kibana/bin/kibana >/dev/null 2>&1 &"

# netstat -tnlp  //启用端口为5601

http://10.66.3.155:5601 //可以看到网页内容
# vim /etc/rc.local //开机自启动

su -l -c "nohup /opt/logstash/bin/logstash -f /opt/logstash/config/log_indexer_tomcat_catalina_local_250.conf >/dev/null 2>&1 &"

四、Monitor Nginx Log

4.1 只监控access日志，，从文件获取将access日志导向服务端的redis

客户端

# vim /opt/logstash-2.3.1/conf/log_agent_nginx_access.conf  //定义一个实例配置，从access.log获取日志并存储至redis

input {
    file {
        type => "nginx access log"
        path => ["/var/log/nginx/access.log"] 
    }
}
output {
    redis {
        host => "10.66.3.155"
        port => "6379"
        data_type => "list"
        key => "nginx_access_136:redis"
    }
}

# /opt/logstash-2.3.1/bin/logstash -f /opt/logstash-2.3.1/conf/log_nginx_access.log  //启动实例测试,正常显示如下

Settings: Default pipeline workers: 8 Pipeline main started

ctrl + c 退出

# nohup /opt/logstash-2.3.1/bin/logstash -f /opt/logstash-2.3.1/conf/log_nginx_access.log >nohup &  //放至后台运行
 # vim /etc/rc.local  //开机自启动

su -l -c "nohup /opt/logstash/bin/logstash -f /opt/logstash/config/log_nginx_access.log >/dev/null 2>&1 &"

服务端

# redis-cli  //登录redis
# 127.0.0.1:6379> exists nginx_access_136:redis

(integer) 1 //如果存在会显示这个

# vim /opt/logstash-2.3.1/config/log_indexer_nginx_access_136.conf  //从redis获取键名为nginx_access_136:redis的日志，将之过虑并导向elasticsearch

input {
    redis {
        host => "10.66.3.155"
        port => "6379"
        data_type => "list"
        key => "nginx_access_136:redis"
        type => "redis-input"
        }
}
 
filter {
    if [type] =~ "nginx access log" {
        mutate {
            replace => { "type" => "apache_access" }
        }
        grok {
            match => { "message" => "%{COMBINEDAPACHELOG}" }
        }
    }
 
    date {
        match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
    }
}
 
output {
    elasticsearch {
        hosts => "10.66.3.155:9200"
    }
    stdout { codec => rubydebug }
}

# logstash -f /opt/logstash-2.3.1/config/log_indexer_nginx_access_136.conf  //启动一个实例，如果正常会显示如下信息

{ "message" => "10.66.0.1 - - [15/Apr/2016:12:30:05 +0800] \"POST /weixin/services/SysServiceLog?wsdl HTTP/1.0\" 200 594 \"-\" \"Axis/1.4\"", "@version" => "1", "@timestamp" => "2016-04-15T04:30:05.000Z", "path" => "/opt/nginx/logs/access.log", "host" => "LO-T-DEMO-AP", "type" => "apache_access", "clientip" => "10.66.0.1", "ident" => "-", "auth" => "-", "timestamp" => "15/Apr/2016:12:30:05 +0800", "verb" => "POST", "request" => "/weixin/services/SysServiceLog?wsdl", "httpversion" => "1.0", "response" => "200", "bytes" => "594", "referrer" => "\"-\"", "agent" => "\"Axis/1.4\"" }

# vim /etc/rc.local  //设置开机启动

su -l -c "nohup /opt/logstash/bin/logstash -f /opt/logstash/config/log_indexer_nginx_access_136.conf >/dev/null 2>&1 &"

4.2 同时监控access、error日志，，从文件获取将access、error日志导向服务端的redis

客户端

# vim /opt/logstash-2.3.1/conf/log_agent_nginx_all.conf  //定义一个实例配置，从access.log、error*.log获取日志并存储至redis

input {
    file {
        path => "/opt/nginx/logs/access.log"
        type => "nginx_access"
    }
    file {
        path => "/opt/nginx/logs/erro*.log"
        type => "nginx_error"
    }
}
 
output {
    redis {
        host => "10.66.3.155"
        port => "6379"
        data_type => "list"
        key => "nginx_all_136:redis"
    }

# 127.0.0.1:6379> exists nginx_all_136:redis

(integer) 1 //如果存在会显示这个

# vim /opt/logstash-2.3.1/config/log_indexer_nginx_all_136.conf  //从redis获取键名为`nginx_all_136:redis`的日志，将之过虑并导向elasticsearch  

input {
    redis {
        host => "10.66.3.155"

五、Monitor System Log

5.1Client rsyslog Install (If not installed)

客户端

# yum install rsyslog

5.2 The configuration of /etc/rsyslog.conf

客户端

# vim /etc/rsyslog.conf  //在最后一行加上如下所示，5000端口为服务端自定义的，服务端是多少这里就是多少

*.* @10.66.3.155:5000

# vim /etc/bashrc  //定义日常命令操作也记录至syslog日志，最后一行加入如下所示

export PROMPT_COMMAND='{ msg=$(history 1 | { read x y; echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg"; }'

# service rsyslog restart  //重启rsyslog服务

5.3 Start the instance on the server

服务端

# vim /opt/logstash-2.3.1/config/log_agent_136.conf  //定义logstash实例监听在5000端口，接收10.66.3.136发过来的日志

6.2 服务端从redis中提取相应键名的数据，并错误日志通过邮件发送（msmtp + mutt请另行配置）

服务端
# vim /opt/logstash-2.3.1/config/log_indexer_tomcat_catalina_local_250.conf //定义实例，从redis中取得键名为tomcat_catalina_local_250:redis的数据，即取完redis就没有数据了，如果有错误日志则执行mutt命令发送邮件通知

七、kibana Show（可选操作，按个人需求安装与否，安装方式有变，请参考官方文档）

7.1Install Plugin

服务端
head插件: (以查看集群几乎所有信息，还能进行简单的搜索查询，观察自动恢复的情况等等。)

# /opt/elasticsearch-2.3.1/bin/plugin install mobz/elasticsearch-head

kopf插件:(它提供了一个简单的方法，一个elasticsearch集群上执行常见的任务。)

# /opt/elasticsearch-2.3.1/bin/plugin install lmenezes/elasticsearch-kopf/1.6

bigdesk插件: (集群监控插件，通过该插件可以查看整个集群的资源消耗情况，cpu、内存、http链接等等。代码已许久未更新，该插件可能已不再支持)

# /opt/elasticsearch-2.3.1/bin/plugin install lukas-vlcek/bigdesk

7.2 Start Elasticsearch

服务端
上面已经启动了，可以kill掉pid，再重新启动

7.3 Kibana Usage

通过插件查看集群状态
