rsyslog+loganalyzer+mysql+apache+php的lamp架构搭建日志服务器
当服务器遇到问题时，运维工程师都会根据日志分析问题，当黑客入侵服务器时，基本都会删除日志，以免留下蛛丝马迹，由此可见日志对服务器来说多么重要，为此很多公司都会有自己的日志服务器，下面我们来一起学习如何搭建日志服务器和日志分析工具。 1.首先必须得客户机与服务器都安装rsyslog这个软件:# yum -y install rsyslog
2.客户机修改配置文件（1.4为日志服务器）
# grep -v "^$" /etc/rsyslog.conf | grep -v "^#"
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imklog # provides kernel logging support (previously done by rklogd)
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
*.* @192.168.1.4
*.* :ommysql:192.168.1.4,Syslog,syslogroot,syslogpass
local7.* /var/log/boot.log
修改完成后重启服务并开机自动运行
# service rsyslog restart
关闭系统日志记录器： [确定]
启动系统日志记录器： [确定]
# chkconfig rsyslog on
3.服务器修改配置文件
# grep -v "^$" /etc/rsyslog.conf | grep -v "^#"
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imklog # provides kernel logging support (previously done by rklogd)
$ModLoad imudp
$UDPServerRun 514
$ModLoad imtcp
$InputTCPServerRun 514
$Modload ommysql
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
*.* :ommysql:192.168.1.4,Syslog,syslogroot,syslogpass
local7.* /var/log/boot.log
重启服务器并开机自动运行
~]# service rsyslog restart
~]# chkconfig rsyslog on
4.安装配置数据库
~]# yum -y install mysql-server rsyslog-mysql
（2）配置数据库
# rpm -ql rsyslog-mysql #首先查看rsyslog-mysql安装生成了那些文件
/lib64/rsyslog/ommysql.so
/usr/share/doc/rsyslog-mysql-5.8.10
/usr/share/doc/rsyslog-mysql-5.8.10/createDB.sql #此sql文件就是需要导入到数据库中的数据文件
#
# service mysqld start #启动mysqld服务
# mysql #连接mysql

5.配置lamp+loganalyzer架构
1、安装LAMP环境
# yum -y install httpd php php-mysql php-gd
# mkdir /var/www/html/loganalyzer/
mkdir: created directory `/var/www/html/loganalyzer/'
2、解压loganalyzer源码包
# tar xf loganalyzer-3.6.5.tar.gz
# cd loganalyzer-3.6.5
#
# ls
ChangeLogcontribCOPYINGdocINSTALLsrc
# mv src/* /var/www/html/loganalyzer/ #src下是php的网页文件
# ls contrib/
configure.shsecure.sh
# mv contrib/* /var/www/html/loganalyzer/ #contrib目录下的两个脚本，可以打开看看
#
# cd /var/www/html/loganalyzer/
# sh configure.sh #执行脚本
3、配置httpd
修改DocumentRoot网页根目录
# vim /etc/httpd/conf/httpd.conf
DocumentRoot "/var/www/html/loganalyzer"
# service httpd start
4、配置httpd和mysql开机启动
# chkconfig mysqld on
# chkconfig httpd on
5、创建loganalyzer数据库，并授权
# mysql
Enter password:
mysql> create database loganalyzer;
Query OK, 1 row affected (0.04 sec)
mysql> grant all on loganalyzer.* to min@'192.168.1.4' identified by 'liwai8888';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
6.配置安装界面
主要错误在数据库的大小写以及数据库的用户名密码，一般都要安装2次，第2次必须删除里面的config.php，然后再在下一步运行sh configure.sh生成config.php。然后你并可以开始使用它了。（不知道为啥复制不了图，所以只能这样谈谈我遇到的错误与解决方法）。
