复制提示

一、系统环境

Rsyslog Server OS：CentOS 7

Rsyslog Server IP：172.28.194.118

Rsyslog Version: rsyslog-7.4.7-12.el7.x86_64

LogAnalyzer Version: loganalyzer-4.1.7.tar.gz

rsyslog-8.24.0-12.el7.x86_64（centos7默认安装）

二、准备环境

2.1 关闭防火墙：

#systemctl stop firewalld
2.2 将SELINUX设置为disabled
setenforce 0
sed -i ‘s#SELINUX=enforcing#SELINUX=disabled#g’ /etc/selinux/config

三、配置LAMP环境

3.1
配置LAMP

yum
-y install httpd mysql* php*

mkdir
/home/rsyslog_server/tools -p （创建下载文件存放目录）

cd
/home/rsyslog_server/tools

yum
install wget -y

wget
http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

rpm
-Uvh mysql57-community-release-el7-8.noarch.rpm （安装mysql官方yum仓库）

yum
install mysql-community-server -y

systemctl
start mysqld.service

systemctl
status mysqld.service

grep
‘temporary password’ /var/log/mysqld.log （查看初始密码，记录好初始密码，红色圈文字为初始密码）

mysql -u root -p

提示输入密码：输入刚才查看的初始密码

输入密码号，再修改密码，如下命令！

ALTER
USER 'root'@'localhost' IDENTIFIED BY 'Lanqing@123'; （修改密码）

3.2
配置Apache和PHP

yum
install httpd -y

yum
install php php-gd php-xml php-mysql -y

3.3
启动服务并加入开机自启动：

systemctl
start httpd.service

systemctl
enable httpd.service

systemctl
start mysqld.service

systemctl
enable mysqld.service

3.4 测试PHP环境
[root@localhost
~]# cd /var/www/html/
[root@localhost html]# vim index.php

<?php

phpinfo();

打开浏览器访问：http://172.28.194.118/index.php

四、安装服务器端软件

4.1
检查是否安装了rsyslog软件

rpm
-qa|grep rsyslog

4.2
安装rsyslog 连接MySQL数据库的模块

yum
install rsyslog-mysql –y

五、配置服务器端

5.1
导入rsyslog-mysql 数据库文件

cd
/usr/share/doc/rsyslog-8.24.0

mysql
-uroot -p<mysql-createDB.sql

5.2
登录数据库查看

mysql
-uroot –p

5.3
在MySQL下创建rsyslog用户并授权：

mysql>
grant all on Syslog.* to rsyslog@‘localhost’ identified by 'Lanqing@123'

mysql>
flush privileges;

mysql>
exit

5.4
配置服务端支持rsyslog-mysql 模块，并开启UDP服务端口获取网内其他LINUX系统日志；

以下为重点需要修改的地方！!!!!

vi /etc/rsyslog.conf

# Provides UDP syslog reception

$ModLoad imudp

$UDPServerRun 514

# Provides TCP syslog reception

$ModLoad imtcp

$InputTCPServerRun 514

$ModLoad ommysql

*.* :ommysql:localhost,Syslog,rsyslog,Vxichina@123

# Use default timestamp format

$ActionFileDefaultTemplate
RSYSLOG_TraditionalFileFormat

$template Remote,"/var/log/data/%fromhost-ip%/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log"

:fromhost-ip, !isequal,
"127.0.0.1" ?Remote

#Standard Redhat syslog settings

.info;mail.none;authpriv.none;cron.none
/var/log/messages

authpriv. /var/log/secure

mail.* -/var/log/maillog

cron.* /var/log/cron

.emerg *

uucp,news.crit /var/log/spooler

# Save boot messages also to
boot.log

local7.*
/var/log/boot.log

$template MySQLInsert,"insert
into SystemEvents (Message, Facility, FromHost,Priority, DeviceReportedTime,
ReceivedAt, InfoUnitID, SysLogTag) values ('%msg%', %syslogfacility%,
'%fromhost-ip%', %syslogpriority%, '%timereported:::date-mysql%',
'%timegenerated:::date-mysql%', %iut%, '%syslogtag%')",SQL

客户端配置：（服务端可以不配置）

再末尾添加服务器IP地址（接收日志的服务器IP）

#vi /etc/rsyslog.conf
*.* @172.28.194.118

vi
/etc/bashrc

在文件尾部增加一行

export
PROMPT_COMMAND=’{ msg=$(history 1 | { read x y; echo KaTeX parse error:
Expected 'EOF', got '}' at position 4: y; }̲);logger "[euid…(whoami)]":(whoami):[‘pwd‘]"
(who am i):[`pwd`]"(whoami):[‘pwd‘]"msg"; }’

#source
/etc/bashrc -----------------使其生效

六、安装LogAnalyzer

cd
/home/rsyslog_server/tools/

wget
http://download.adiscon.com/loganalyzer/loganalyzer-4.1.7.tar.gz

tar
zxf loganalyzer-4.1.7.tar.gz

cd
loganalyzer-4.1.7

mkdir
-p /var/www/html/loganalyzer

cp
-rf src/* /var/www/html/loganalyzer/

cp
-rf contrib/* /var/www/html/loganalyzer

重启服务

systemctl
restart rsyslog.service

systemctl
start mysqld.service
