在centos 6及之前的版本叫做syslog，centos 7开始叫做rsyslog。官方网址：http://www.rsyslog.com/

安装配置rsyslog

## 安装rsyslog
[root@logstash ~]# yum install -y rsyslog

## 编辑rsyslog配置文件
[root@logstash ~]# vim /etc/rsyslog.conf
 15行 $ModLoad imudp
 16行 $UDPServerRun 514
 19行 $ModLoad imtcp 
 20行 $InputTCPServerRun 514
最后一行加入
local7.*     @@10.0.0.91:2222

## 启动服务
[root@logstash ~]# systemctl start rsyslog

# 检查进程
[root@logstash ~]# ps -ef | grep rsyslog

  • logstash监听了2222端口

  • rsyslog是接收到了haproxy的日志然后转发给10.0.0.83:2222

  • logstash启动2222端口实时接受rsyslog传来的日志

  • 如果logstash停掉 2222消失，2222是logstash起的
