访问elkIP:5601验证kibana安装
做端口转发，将对端口80的访问转发到5601上（方便访问,非必须）
[root@elk src]# firewall-cmd --permanent --add-forward-port=port=80:proto=tcp:toport=5601
success
[root@elk src]# firewall-cmd --reload
success
4.安装logstash，添加配置文件
[root@elk src]# yum localinstall logstash-2.3.2-1.noarch.rpm -y
生成证书
[root@elk tls]# openssl req -subj '/CN=elk.test.com/' -x509 -days 3650 -batch -nodes -newkey rsa:2048 -keyout private/logstash-forwarder.key -out certs/logstash-forwarder.crt
Generating a 2048 bit RSA private key
.........+++
.+++
writing new private key to 'private/logstash-forwarder.key'
-----
创建logstash的配置文件
[root@elk tls]# vim /etc/logstash/conf.d/01-logstash-initial.conf
input {
beats {
port => 5000
type => "logs"
ssl => true
ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
}
}
filter {
if [type] == "syslog-beat" {
grok {
match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
add_field => [ "received_at", "%{@timestamp}" ]
add_field => [ "received_from", "%{host}" ]
}
geoip {
source => "clientip"
}
syslog_pri {}
date {
match => [ "syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss" ]
}
}
}
output {
elasticsearch { }
stdout { codec => rubydebug }
}
启动logstash检查端口
[root@elk tls]# systemctl start logstash
[root@elk tls]# /sbin/chkconfig logstash on
[root@elk tls]# netstat -ntlp
Active Internet connections (only servers)

修改防火墙，开放5000端口
[root@elk src]# firewall-cmd --permanent --add-port=5000/tcp
success
[root@elk src]# firewall-cmd --reload
success
5.修改elasticsearch配置文件
[root@elk elasticsearch]# mkdir es-01
[root@elk elasticsearch]# mv elasticsearch.yml es-01/
[root@elk elasticsearch]# mv logging.yml es-01/
[root@elk elasticsearch]# tree
.
├── es-01
│ ├── elasticsearch.yml
│ └── logging.yml
└── scripts
2 directories, 2 files
[root@elk elasticsearch]# cat es-01/elasticsearch.yml
http:
port: 9200
network:
host: elk.test.com
node:
name: elk.test.com
path:
data: /etc/elasticsearch/data/es-01
重启elasticsearch和logstash服务
[root@elk elasticsearch]# systemctl restart elasticsearch
[root@elk elasticsearch]# systemctl restart logstash
6.将fiebeat安装包拷贝到rsyslog、nginx客户端上
[root@elk elk]# scp filebeat-1.2.3-x86_64.rpm [email protected]:/root/elk
[root@elk elk]# scp filebeat-1.2.3-x86_64.rpm [email protected]:/root/elk
[root@elk elk]# scp /etc/pki/tls/certs/logstash-forwarder.crt rsyslog.test.com:/root/elk
[root@elk elk]# scp /etc/pki/tls/certs/logstash-forwarder.crt nginx.test.com:/root/elk
7.在rsyslog上安装filebeat
[root@rsyslog src]# yum localinstall filebeat-1.2.3-x86_64.rpm -y
[root@rsyslog src]# cp logstash-forwarder.crt /etc/pki/tls/certs/.
[root@rsyslog src]# cd /etc/filebeat/
[root@rsyslog filebeat]# tree
.
├── conf.d
│ ├── authlogs.yml
│ └── syslogs.yml
├── filebeat.template.json
└── filebeat.yml
[root@rsyslog filebeat]# vim filebeat.yml
filebeat:
spool_size: 1024
idle_timeout: 5s
registry_file: .filebeat
config_dir: /etc/filebeat/conf.d
output:
logstash:

[root@rsyslog filebeat]# vim conf.d/authlogs.yml

harvester_buffer_size: 16384
tail_files: false
force_close_files: false
backoff: 1s
max_backoff: 1s
backoff_factor: 2
partial_line_waiting: 5s
max_bytes: 10485760
[root@rsyslog filebeat]# vim conf.d/syslogs.yml
filebeat:
prospectors:
- paths:
- /var/log/messages
encoding: plain
fields_under_root: false
input_type: log
ignore_older: 24h
document_type: syslog-beat

force_close_files: false
backoff: 1s
max_backoff: 1s
backoff_factor: 2
partial_line_waiting: 5s
max_bytes: 10485760
8.修改完成，启动filebeat服务（时间要一致，否则报X509错误）
[root@rsyslog filebeat]# service filebeat start
Starting filebeat: [确定]
[root@rsyslog filebeat]# chkconfig filebeat on
9.安装Nginx在nginx上安装filebeat,拷贝证书，创建收集日志配置文件
[root@nginx ~]# yum -y install nginx-1.8.0-1.el6.ngx.x86_64.rpm
[root@nginx ~]# service nginx start
Starting nginx: [ OK ]
[root@nginx src]# yum localinstall filebeat-1.2.3-x86_64.rpm -y
[root@nginx src]# cp logstash-forwarder.crt /etc/pki/tls/certs/.
[root@nginx src]# cd /etc/filebeat/
....
....
(配置同上7、8)
10.这时filebeat进程已经和elk服务器连接了，浏览器访问elkIP验证
创建
检查所有日志
检查nginx服务器的日志
