CentOS6.3 日志服务器的配置

一.与CentOS5使用syslog来记录日志不同，CentOS6.3利用rsyslog来记录，所以配置上略有不同。

二.CentOS5日志服务器配置

1.Server端：修改/etc/sysconfig/syslog

找到SYSLOGD_OPTIONS=”-m 0 “

改成SYSLOGD_OPTIONS=”-m 0 –r “

2.Client端：修改/etc/syslog.conf

新增服务器的地址

*.*  @192.168.1.117

三.CentOS6.3日志服务器配置

1.Server端：

修改/etc/rsyslog.conf，将以下注释去除：

开放防火墙端口：在iptables.rule中新增以下二行

重新执行iptables.rule.

重启rsyslog服务 /etc/init.d/rsyslog restart

2.Client端：修改/etc/rsyslog.conf，将以下注释去除：

 

3.重启rsyslog服务：/etc/init.d/rsyslog restart.

附：iptables.rule文件：

iptables.rule#!/bin/bash
