rsyslog+loganalyzer配置

1、loganalyzer服务器搭建
[root@localhost ~]# getenforce #查看selinux是否关闭
[root@localhost ~]# setenforce 0 #临时关闭;修改配置文件/etc/selinux/config,将其中SELINUX设置为disabled(永久关闭)
[root@localhost ~]# systemctl status firewalld.service
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# yum install mariadb mariadb-server -y
[root@localhost ~]# systemctl start mariadb.service
[root@localhost ~]# /bin/mysql_secure_installation      #初始化mariadb数据库
[root@localhost ~]# yum install rsyslog-mysql -y
[root@localhost ~]# mysql -uroot -proot </usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql

MariaDB [(none)]> grant all privileges on Syslog.* to 'rsyslog'@'%' identified by 'rsyslog';flush privileges;

[root@localhost ~]# vim /etc/rsyslog.d/loganalyzer.conf

$ModLoad ommysql
#所有日志 :ommysql:数据库地址,数据库名,登陆数据库的用户,用户密码
*.* :ommysql:localhost,Syslog,rsyslog,rsyslog
#使用UDP协议传输
$ModLoad imudp
$UDPServerRun 514
$UDPServerRun 38514
#使用TCP协议传输（两者可同时使用）
$ModLoad imtcp
$InputTCPServerRun 514
$InputTCPServerRun 38514

[root@localhost ~]# systemctl restart rsyslog.service
[root@localhost ~]# yum install httpd php php-mysql php-gd -y
[root@localhost ~]# wget http://download.adiscon.com/loganalyzer/loganalyzer-4.1.7.tar.gz
[root@localhost ~]# cp -a loganalyzer-master/src/* /var/www/html/
[root@localhost ~]# systemctl start httpd.service
[root@docker ~]# vim /var/www/html/hello.php      #创建php测试页

<?php phpinfo(); ?>

[root@localhost ~]# touch /var/www/html/config.php
[root@localhost ~]# chmod 666 /var/www/html/config.php
[root@localhost ~]# vim /var/www/html/include/functions_common.php #关闭loganalyzer的资助信息(true改为false)

72 $content['SHOW_DONATEBUTTON'] = false; // Default = true!

2、Web页面配置：


思科交换机日志推送
logging trap informational
logging facility local5     #把日志发送到rsyslog的local5设备
logging host 10.10.10.10

ASA防火墙日志推送
logging enable
logging timestamp
logging trap informational
logging facility 21 #21对应local5
logging host inside 10.10.10.10

3、nginx日志发送到日志服务器
rsyslog服务器配置

[root@rsyslog ~]# grep -vE "^$|#" /etc/rsyslog.conf
$ModLoad imudp
$UDPServerRun 514
$ModLoad imtcp
$InputTCPServerRun 514
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
$OmitLocalLogging on
$IMJournalStateFile imjournal.state
*.info;mail.none;authpriv.none;cron.none;local5.none    /var/log/messages
authpriv.*                                              /var/log/secure
mail.*                                                  -/var/log/maillog
cron.*                                                  /var/log/cron
*.emerg                                                 :omusrmsg:*
uucp,news.crit                                          /var/log/spooler
local7.*                                                /var/log/boot.log
$ModLoad ommysql
local5.* :ommysql:localhost,Syslog,rsyslog,rsyslog

nginx端rsyslog配置

[root@nginx ~]# grep -vE "^$|^#" /etc/rsyslog.conf
$ModLoad imuxsock 
$ModLoad imklog  
$ModLoad imudp
$UDPServerRun 514
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
*.info;mail.none;authpriv.none;cron.none;local5.none    /var/log/messages
authpriv.*                                              /var/log/secure
mail.*                                                  -/var/log/maillog
cron.*                                                  /var/log/cron
*.emerg                                                 *
uucp,news.crit                                          /var/log/spooler
local7.*                                                /var/log/boot.log
local5.*        @10.10.10.10:514      # @@表示通过tcp协议发送;@表示通过udp协议发送

[root@nginx ~]# cat /etc/rsyslog.d/nginx.conf
$ModLoad imfile
$InputFileName /application/nginx-1.14.2/logs/web01.log
$InputFileTag nginx_1:
$InputFileStateFile /application/nginx-1.14.2/logs/pianyi.log  
$InputFileSeverity info
$InputFileFacility local5
$InputRunFileMonitor
$InputFilePollInterval 1
$InputFilePersistStateInterval 1
$ActionQueueSaveOnShutdown on

[root@rsyslog]#logger -p local3.info 'KadeFor is testing the rsyslog and logger'     #产生一条日志
