Logstash收集Syslog日志

准备条件：1）rsyslog服务器端，Centos6.5 、IP地址192.168.174.129

2)rsyslog客户端端，Centos6.5 、IP地址192.168.174.120

3）logstash部署在rssyslog服务端，部署目录是/usr/local/loggstash

4)rsyslog配置文件rsyslog.conf所在的目录是/etc/rssyslog.conf

1、rsyslog服务端配置

# Provides UDP syslog reception
$ModLoad imudp

2、rsyslog客户端配置

3、logstash 配置文件

input {

   file{

      path => "/var/log/mysyslog.log"
   }
}
output {

   file{

      path => "/home/hadoop/xuguokun/syslog.log"
  }
}

4、启动logstash ./logstash -f ../conf/syslog.conf

5、测试方法：在客户端机器上进行ssh Master（rsyslog服务器主机名）

6、查看rsyslog服务器/var/log/mysyslog.log里面内容如下：

2016-05-17T05:48:14.073788-07:00 Master sshd[51654]: Accepted publickey for hadoop from 192.168.174.130 port 47559 ssh2
