Logstash配合rsyslog收集haproxy日志

1.rsyslog介绍

在centos 6及之前的版本叫做syslog，centos 7开始叫做rsyslog，根据官方的介绍，rsyslog(2013年版本)可以达到每秒转发百万条日志的级别，官方网址：http://www.rsyslog.com/

2.安装

[root@web01 ~]# yum isntall -y rsyslog

3.配置rsyslog

[root@web01 ~]# vim /etc/rsyslog.conf
#打开注释
$ModLoad imudp
$UDPServerRun 514
$ModLoad imtcp
$InputTCPServerRun 514
#添加日志收集级别
local6.*       @@172.16.1.52:2222

4.安装haproxy

[root@web01 ~]# yum install -y haproxy

5.配置haproxy

[root@web01 ~]# vim /etc/haproxy/haproxy.cfg
global
maxconn 100000
chroot /var/lib/haproxy
uid 99
gid 99
daemon
nbproc 1
pidfile /var/run/haproxy.pid

6.修改Nginx启动端口

[root@web01 ~]# vim /etc/nginx/nginx.conf
    server {
        listen       8081 default_server;
        ...

7.启动服务

#启动haproxy
[root@web01 ~]# systemctl start haproxy.service

#启动rsyslog
[root@web01 ~]# systemctl start rsyslog

#验证
[root@web01 ~]# netstat -lntp

8.访问状态页面

http://10.0.0.7:9999/haproxy-status
haadmin
123456

9.测试访问Nginx和tomcat

#配置本地hosts
10.0.0.7 www.nginx.com
10.0.0.7 www.tomcat.com

#访问页面
http://www.nginx.com/
http://www.tomcat.com/

10.测试配置收集proxy日志

[root@db02 ~]# vim /etc/logstash/conf.d/haproxy.conf
input {
  syslog {
    port => "2222"
  }
}
output {
  stdout {}
}

#访问haproxy的页面，查看有无输出

11.配置收集proxy日志到ES

[root@db02 ~]# vim /etc/logstash/conf.d/haproxy_es.conf
input {
  syslog {
    port => "2222"
  }
}
output {
  elasticsearch {
    hosts => ["10.0.0.51:9200"]
    index => "haproxy_log_%{+YYYY-MM-dd}"
  }
}
