实验环境：我系统的系统是CentOS6.5的系统，ip为192.168.137.191。安装的所有软件都是官网下载的RPM包，软件分别是Elasticsearch，Logstash，Kibana还有JDK（JRE）。因为Logstash是依赖JDK的所以这个必须安装，在这里安装JRE就可以了，但是我有下载好的JDK包就直接使用了。在实验开始之前依然是要调整服务器时间的。
在此次实验里面我将所有的RPM包都放在了/opt/路径下了，而且在安装的时候并没有指定安装路径。

#cd /usr/share/elasticsearch/
#./bin/plugin install mobz/elasticsearch-head
安装head插件，这是负责集群管理的插件

#./bin/plugin install lmenezes/elasticsearch-kopf
安装kopf插件，在elasticsearch搜索查询日志的插件

#mkdir /es/data -p
#mkdir /es/logs -p
#cp /etc/elasticsearch/elasticsearch.yml /etc/elasticsearch/elasticsearch.yml.bak
将原有的配置文件备份
#vim /etc/elasticsearch/elasticsearch.yml
因为配置文件内都是注释掉的内容直接在最下面添加如下内容
cluster.name: es node.name: node-0 path.data: /es/data path.logs: /es/logs network.host: 192.168.137.191 network.port: 9200
#chkconfig --add elasticsearch
#chkconfig elasticsearch on
因为是rpm包安装的所以启动脚本都有的在/etc/init.d/目录下
#chown -R elasticsearch.elasticsearch elasticsearch/
#chown -R elasticsearch.elasticsearch /etc/elasticsearch/
#chown -R elasticsearch.elasticsearch /es
将安装文件，配置文件归属给elasticsearch用户，因为服务启动都是依赖于elasticsearch用户的
#service elasticsearch start
启动elasticsearch服务
#netstat -luntp
看到下面开始监听来了9200和9300的端口就表示成功了
Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 982/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1058/master tcp 0 0 ::ffff:192.168.137.191:9200 :::* LISTEN 1920/java tcp 0 0 ::ffff:192.168.137.191:9300 :::* LISTEN 1920/java tcp 0 0 :::22 :::* LISTEN 982/sshd tcp 0 0 ::1:25 :::* LISTEN 1058/master
在浏览器地址栏输入http://192.168.137.191:9200/ 就会出现如下信息
{
"name" : "node-0",
"cluster_name" : "es",
"version" : {
"number" : "2.3.4",
"build_hash" : "e455fd0c13dceca8dbbdbb1665d068ae55dabe3f",
"build_timestamp" : "2016-06-30T11:24:31Z",
"build_snapshot" : false,
"lucene_version" : "5.5.0"
},
"tagline" : "You Know, for Search"
}
以上elasticsearch就安装好了，下面开始安装kibana。
#rpm -ivh kibana-4.5.3-1.x86_64.rpm
安装kibana安装包
#chkconfig --add kibana
#chkconfig kibana on
RPM包就是这点好，自动生成启动文件
#service kibana start
启动kibana
#netstat -luntp
发现系统开始监听5601端口了表示kibana正常启动了
Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 982/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1058/master tcp 0 0 0.0.0.0:5601 0.0.0.0:* LISTEN 2095/node tcp 0 0 ::ffff:192.168.137.191:9200 :::* LISTEN 1920/java tcp 0 0 ::ffff:192.168.137.191:9300 :::* LISTEN 1920/java tcp 0 0 :::22 :::* LISTEN 982/sshd tcp 0 0 ::1:25 :::* LISTEN 1058/master
下面开始安装logstash。
#rpm -ivh logstash-all-plugins-2.3.4-1.noarch.rpm
安装logstash
#vim /etc/logstash/conf.d/logstash-test.conf
创建一个logstash的配置文件，测试一下，文件内输入一下内容
input { stdin { } }
output {
elasticsearch {hosts => "192.168.137.191" }
stdout { codec=> rubydebug }
}
#/opt/logstash/bin/logstash --configtest -f /etc/logstash/conf.d/logstash-test.conf
测试配置文件是否正常，出现如下内容表示正常
Configuration OK
#/opt/logstash/bin/logstash -f /etc/logstash/conf.d/logstash-test.conf
使用-f命令指定配置文件，然后输入hello world后系统会打印出输入的内容，使用ctrl+c终止执行
#curl 'http://192.168.137.191:9200/_search?pretty'
输入以上命令后会打印出所有ES接收到的信息
完成以上操作就证明ELK都已经安装好了，但是ES还是不能接受日志，下面调试一些配置文件让ELK工作起来
#vim /opt/kibana/config/kibana.yml
kibana配置文件内都是被注释的内容直接在最下面添加如下内容即可
server.port: 5601 server.host: "192.168.137.191" elasticsearch.url: "http://192.168.137.191:9200" kibana.defaultAppId: "discover" elasticsearch.requestTimeout: 300000 elasticsearch.shardTimeout: 0
#service kibana restart
重启kibana
#vim /etc/logstash/conf.d/logstash-local.conf
重新创建一个logstash的配置文件，让本机的messages和secure日志信息通过5944（我就试试）端口传到ES里面
input {
file {
type => "syslog"
path => ["/var/log/messages", "/var/log/secure" ]
}
syslog {
type => "syslog"
port => "5944"
}
}
output {
elasticsearch { hosts => "192.168.137.191" }
stdout { codec => rubydebug }
}
#/opt/logstash/bin/logstash --configtest /etc/logstash/conf.d/logstash-local.conf
测试配置文件的语法格式
#nohup /opt/logstash/bin/logstash -f /etc/logstash/conf.d/logstash-local.conf &
使用后台静默的方式启动logstash
点击绿色的创建按钮
看到以上界面就证明创建索引完成了可以按照如下操作了。
点击Discover按钮后就可以查看日志了，如果提示没有日志的话就点击右上角的按钮修改显示日志的时间
稍后更新ELK收集nginx日志的方法
