二 客户端配置
linux使用的syslog守护进程主要有两种，syslog和syslog-ng
使用logger -t notice -p user.notice “日志内容” 将一些脚本或crontab的执行结果加入到syslog中，然后输出到log服务器，实现集中管理分析日志。
1、syslog
#vi /etc/syslog.conf
kern.* @loghost
user.notice @loghost
loghost为日志服务器的IP或者主机名，主机明必须能正确解析到日志服务器IP。
然后重新启动syslog服务：
#/etc/init.d/syslog restart
2、syslog-ng
在配置文件syslog-ng.conf中加入两行：
destination d_udp { udp("loghost" port(514)); };
log { source(src); destination(d_udp); };
重新启动syslog-ng服务
#/etc/init.d/syslog-ng restart
winodws服务器的配置
因为windows服务器不支持日志服务器，因此需要安装一个转换软件：
根据系统的版本下载32位和64位的程序。
解压后是两个文件evtsys.dll和evtsys.exe
把这两个文件拷贝到 c:\windows\system32目录下。
打开Windows命令提示符（开始－>运行 输入CMD）
C:\>evtsys –i –h 192.168.10.100 #（日志服务器的IP地址）
-i 表示安装成系统服务
-h 指定log服务器的IP地址
如果要卸载evtsys,则：
net stop evtsys
evtsys -u
启动该服务:
C:\>net start evtsys
