RHEL5.4部署中央日志服务器之rsyslog+loganalyzer

2010-12-21 22:48 417 查看

1 系统需求
mysql mysql-devel mysql-server php php-mysql php-pdo php-common php-gd httpd
2需要的源码包软件
rsyslog-5.6.2.tar.gz
loganalyzer-3.0.4.tar.gz
3安装rsyslog
#tar xvf rsyslog-5.6.2.tar.gz
#./configure --enable-mysql
#make && make install
4 修改rsyslog 的主配置文件
修改如下
#if you experience problems, check

# http://www.rsyslog.com/troubleshoot for assistance

# rsyslog v3: load input modules
# If you do not load inputs, nothing happens!

# You may need to set the module load path if modules are not found.

$ModLoad immark # provides --MARK-- message capability
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)

$ModLoad imklog # kernel logging (formerly provided by rklogd)

$ModLoad ommysql
*.* :ommysql:localhost,Syslog,root,frank

# 注 localhost 字节是database-server

Syslog 是数据中database-name

root 是database-userid

frank 是root用户登录mysql的密码

#该行的格式

#*.* :ommysql:database-server,database-name,database-userid,database-password

#同样要注意的是database-name 必须和/root/rsyslog-5.6.2/plugins/ommysql/creatDB.sql 中的相同

# 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

# Remote Logging (we use TCP for reliable delivery)

# An on-disk queue is created for this action. If the remote host is

# down, messages are spooled to disk and sent when it is up again.

#$WorkDirectory /rsyslog/spool # where to place spool files

#$ActionQueueFileName uniqName # unique name prefix for spool files

#$ActionQueueMaxDiskSpace 1g # 1gb space limit (use as much as possible)
#$ActionQueueSaveOnShutdown on # save messages to disk on shutdown

#$ActionQueueType LinkedList # run asynchronously
#$ActionResumeRetryCount -1 # infinite retries if host is down
# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional

#*.* @@remote-host:514

# ######### Receiving Messages from Remote Hosts ##########

# TCP Syslog Server:
# provides TCP syslog reception and GSS-API (if compiled to support it)

#$ModLoad imtcp.so # load module
#$InputTCPServerRun 514 # start up TCP listener at port 514

########## 下面的配置接受远程主机的日志
UDP Syslog Server:
$ModLoad imudp.so # provides UDP syslog reception
$UDPServerRun 514 # start a UDP syslog server at standard port 514

5 关闭系统自带的syslog 进程
#service syslog stop

#chkconfig syslog off

6 因为rsyslog 没有启动脚本，并修改该脚本此时用的是syslog的启动脚本，
#cp /etc/init.d/{syslog,rsyslog}
把脚本中syslog 替换成rsyslog
#sed -i ‘s/syslog/rsyslog/g’ /etc/init.d/rsyslog

#chmod 700 /etc/init.d/rsyslog
#chkconfig –add rsyslog
#chkconfig rsyslog on
7 创建一下链接，不然在启动rsyslog 时回报错

# ln -sv /usr/local/rsyslog/sbin/rsyslogd /sbin/rsyslogd

8 导入数据库
#cd /root/rsyslog-5.6.2/plugins/ommysql

#mysql -uroot –pfrank < createDB.sql
9 启动rsyslog 并验证
#service rsyslog restart

#mysql –uroot -pfrank

Mysql>use database Syslog;

Msql> select * from SystenEvents

# 如果上面的配置无误的情况可以查看一些新日志信息
10 安装loganalyzer 并修改权限

#tar xvf loganalyzer-3.0.4.tar.gz

#cd loganalyzer-3.0.4

#cp -r src/ /var/www/html/loganalyzer

#cp -r contrib/* /var/www/html/loganalyzer

#chown -R apache.apache /var/www/html/loganalyzer

11 通过web 形式安装loganalyzer ，在安装之前必须先执行以下两个脚本

#bash /var/www/html/loganalyzer/configure.sh

#bash /var/www/html/loganalyzer/secure.sh

在浏览器在中

http://IP/loganalyzer

注：该IP 为您的日志服务器

12 安装咯疙loganalyzer
