rsyslog+loganalyzer+evtsys搭建集中式监控系统

一、服务端的安装

YUM源新建，如果有的话，可以省略

# cat >> /etc/yum.repos.d/sohu.repo <<EOF
[sohu]
name=sohu's mirrors
baseurl=http://mirrors.sohu.com/centos/5/os/x86_64/
enabled=1
gpgcheck=0
EOF

安装LAMP环境及rsyslog，如果有LAMP，只需要安装rsyslog rsyslog-mysql即可

yum install rsyslog rsyslog-mysql mysql mysql-devel mysql-server php php-mysql php-pdo php-common php-gd httpd

导入rsyslog数据库

mysql -u root -p < $(rpm -ql rsyslog-mysql | grep sql$)

创建数据库用户

mysql -u root -p
mysql> grant all privileges on Syslog.* to logger@localhost identified by 'logger';
mysql> flush privileges;
mysql> exit;

修改rsyslog的配置文件

# vi /etc/rsyslog.conf     //修改一下即可
# Use traditional timestamp format
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

# Provides kernel logging support (previously done by rklogd)
# Provides support for local system logging (e.g. via logger command)
$ModLoad immark
$ModLoad imuxsock
$ModLoad imklog

$ModLoad ommysql
*.* :ommysql:127.0.0.1,Syslog,logger,logger

$ModLoad imudp.so
$UDPServerRun 514

# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.*                                                 /dev/console
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none                /var/log/messages
# The authpriv file has restricted access.
authpriv.*                                              /var/log/secure
# Log all the mail messages in one place.
mail.*                                                  -/var/log/maillog
# Log cron stuff
cron.*                                                  /var/log/cron

# Everybody gets emergency messages
*.emerg                                                 *
# Save news errors of level crit and higher in a special file.
uucp,news.crit                                          /var/log/spooler

# Save boot messages also to boot.log
local7.*                                                /var/log/boot.log

红色部分是添加的，其它的对比一下，有的就略过，没的就添加一下吧。

安装LogAnalyzer

# wget http://download.adiscon.com/loganalyzer/loganalyzer-3.6.3.tar.gz
# tar xf loganalyzer-3.6.3.tar.gz
# mkdir /var/www/html/loganalyzer
# mv loganalyzer-3.6.3/src/* /var/www/html/loganalyze
# touch /var/www/html/loganalyzer/config.php
# chmod 666 /var/www/html/loganalyzer/config.php

通过浏览器安装即可

以上就完成了loganalyzer的安装，登陆查看

二、Windows客户端安装

下载evtsys  http://code.google.com/p/eventlog-to-syslog/

解压缩放到 C:\Windows\System32
evtsys -i -s 10 -h log-server-ip -p 514
net start evtsys

在安装的时候，会报一个错误，是配置文件的问题，可以忽略不用管，只要看到最后的安装成功即可。以下附上详细的参数

Version: 4.4 (32-bit)
Usage: evtsys.exe -i|-u|-d [-h host] [-b host] [-f facility] [-p port]
       [-s minutes] [-l level] [-n]
  -i           Install service
  -u           Uninstall service
  -d           Debug: run as console program
  -h host      Name of log host
  -b host      Name of secondary log host (optional)
  -f facility  Facility level of syslog message
  -l level     Minimum level to send to syslog.\n", stderr);
0=All/Verbose, 1=Critical, 2=Error, 3=Warning, 4=Info
  -n           Include only those events specified in the config file.
  -p port      Port number of syslogd
  -q bool      Query the Dhcp server to obtain the syslog/port to log to
               (0/1 = disable/enable)
  -s minutes   Optional interval between status messages. 0 = Disabled

Default port: 514
Default facility: daemon
Default status interval: 0
Host (-h) required if installing.

以下是在Loganalyzer上看到的Windows的日志，很明显的windows日志。监控Linux日志就很简单了，直接修改配置文件，把日志发送一份到日志服务器即可，这里不再详细的说明。
