RHEL5.4部署中央日志服务器之rsyslog+loganalyzer

  

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 

              

 

13

      

14 在安装前先执行  

    #cd  /var/www/html/loganayzer

    #bash  configure.php  

    #chmod   666  config.php

       

15   注意数据库名，为了安全，不要使用root用户
