使用syslog-ng搭建日志服务器[/b]
|
|
|
一、环境
Gentoo-2007.0_amd64
二、安装：为了简便，我用了系统自带的syslog-ng
三、服务器配置：
#cat /etc/syslog-ng/syslog-ng.conf
#
# configuration file for syslog-ng, customized for remote logging
#
options {
use_fqdn(yes);
chain_hostnames(off);
keep_hostname(off);
sync(0);
# The default action of syslog-ng 1.6.0 is to log a STATS line
# to the file every 10 minutes. That's pretty ugly after a while.
# Change it to every 12 hours so you get a nice daily update of
# how many messages syslog-ng missed (0).
stats(43200);
create_dirs(yes);
};
source s_internal { internal(); };
destination d_syslognglog { file("/var/log/syslog-ng.log"); };
log { source(s_internal); destination(d_syslognglog); };
source s_sys { file ("/proc/kmsg" log_prefix("kernel: ")); unix-stream ("/dev/log"); internal(); };
destination d_cons { file("/dev/console"); };
destination d_mesg { file("/var/log/messages"); };
destination d_auth { file("/var/log/secure"); };
destination d_mail { file("/var/log/maillog"); };
destination d_spol { file("/var/log/spooler"); };
destination d_boot { file("/var/log/boot.log"); };
destination d_cron { file("/var/log/cron"); };
destination d_rsync { file("/var/log/rsync"); };
destination d_mlal { usertty("*"); };
filter f_filter1 { facility(kern); };
filter f_filter2 { level(info) and
not (facility(mail)
or facility(authpriv) or facility(cron)); };
filter f_filter3 { facility(authpriv); };
filter f_filter4 { facility(mail); };
filter f_filter5 { level(emerg); };
filter f_filter6 { facility(uucp) or
(facility(news) and level(crit)); };
filter f_filter7 { facility(local7); };
filter f_filter8 { facility(cron); };
filter f_filter9 { facility(daemon); };
filter f_filter10 { facility(local6); };
#log { source(s_sys); filter(f_filter1); destination(d_cons); };
log { source(s_sys); filter(f_filter2); destination(d_mesg); };
log { source(s_sys); filter(f_filter3); destination(d_auth); };
log { source(s_sys); filter(f_filter4); destination(d_mail); };
log { source(s_sys); filter(f_filter5); destination(d_mlal); };
log { source(s_sys); filter(f_filter6); destination(d_spol); };
log { source(s_sys); filter(f_filter7); destination(d_boot); };
log { source(s_sys); filter(f_filter8); destination(d_cron); };
# Remote logging
source s_remote {
udp(ip(0.0.0.0) port(514));
};
destination r_mesg { file("/var/log/syslog-ng/$YEAR/$MONTH/$HOST/messages" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_auth { file("/var/log/syslog-ng/$YEAR/$MONTH/$HOST/secure" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_mail { file("/var/log/syslog-ng/$YEAR/$MONTH/$HOST/maillog" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_spol { file("/var/log/syslog-ng/$YEAR/$MONTH/$HOST/spooler" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_boot { file("/var/log/syslog-ng/$YEAR/$MONTH/$HOST/boot.log" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_cron { file("/var/log/syslog-ng/$YEAR/$MONTH/$HOST/cron" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_daemon { file("/var/log/syslog-ng/$YEAR/$MONTH/$HOST/daemon" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_local6 { file("/var/log/syslog-ng/$YEAR/$MONTH/network/messages" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
#destination d_separatedbyhosts {
# file("/var/log/syslog-ng/$HOST/messages" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes));
#};
#log { source(s_remote); destination(d_separatedbyhosts); };
log { source(s_remote); filter(f_filter2); destination(r_mesg); };
log { source(s_remote); filter(f_filter3); destination(r_auth); };
log { source(s_remote); filter(f_filter4); destination(r_mail); };
log { source(s_remote); filter(f_filter6); destination(r_spol); };
log { source(s_remote); filter(f_filter7); destination(r_boot); };
log { source(s_remote); filter(f_filter8); destination(r_cron); };
log { source(s_remote); filter(f_filter9); destination(r_daemon); };
log { source(s_remote); filter(f_filter10); destination(r_local6); };
四、客户端配置
linux使用的syslog守护进程主要有两种，syslog和syslog-ng
1、syslog
#vi /etc/syslog.conf
*.* @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：
下载地址为：https://engineering.purdue.edu/ECN/Resources/Documents/UNIX/evtsys/
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
配置完成:) |
