配置AWstats日志分析軟件

需求描述
管理員搭建完服務器，要對網站的性能做后期的不斷的分析和調整，以至達到最完美的狀態。針對服務器每天的日志訪問量、高峰時間、壓力等等是通過日志信息系統分析。如果事前沒有預估，沒有給定足相應的cpu、內存。假如有一天突然高發值，服務器會直接崩潰。通過觀察日志，以便在以后工作調整中提出整改方案。

簡介
在httpd服務器的訪問日志文件access_log中，記錄了大量的客戶機訪問信息,通過分析這些信息,可以及時了解Web站點的訪問情況，通過AWStats日志分析系統,以完成自動化的日志分析與統計工作。通過AWStats日志分析系統可用來分析Apache、 Samba、Vsftpd、IIs等服務器的訪問日志信息。

實驗環境
系統環境：centos7 64
服務器ip地址：192.168.40.15

搭建步驟：

一、準備工作

1.關閉防火墻及selinux

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# vi /etc/sysconfig/selinux

[root@localhost ~]# reboot #重啟Linux生效

二、搭建httpd服務

[root@localhost ~]# yum -y install httpd
[root@localhost ~]# vim /etc/httpd/conf/httpd.conf #修改主配置文件

[root@localhost ~]# systemctl start httpd #啟動httpd 服務

[root@localhost ~]# echo "<h2>Hello everyone</h2>" > /usr/local/httpd/htdocs/index.html #設置默認首頁

測試頁面

三、搭建AWStats日志分析系統

1、配置AWstats日志分析軟件

apachectl -D DUMP_MODULES | grep cgi //確認加載了cgi模塊
ls /usr/local/httpd/modules/ | grep cgi //確認是否編譯過cgi模塊

vi /usr/local/httpd/conf/httpd.conf //手動加載
LoadModule cgid_module modules/mod_cgid.so
LoadModule cgi_module modules/mod_cgi.so

2、上傳或安裝AWStats軟件包

[root@localhost ~]# tar xf awstats-7.6.tar.gz

[root@localhost ~]# mv awstats-7.6 /usr/local/awstats #將源碼剪切至/usr/local目錄下
[root@localhost ~]# cd /usr/local/awstats/tools/
[root@localhost ~]# chmod +x awstats_configure.pl #將配置腳本賦予執行權限
[root@localhost tools]# ./awstats_configure.pl

----- AWStats awstats_configure 1.0 (build 20140126) (c) Laurent Destailleur -----
This tool will help you to configure AWStats to analyze statistics for
one web server. You can try to use it to let it do all that is possible
in AWStats setup, however following the step by step manual setup
documentation (docs/index.html) is often a better idea. Above all if:

• You are not an administrator user,
• You want to analyze downloaded log files without web server,
• You want to analyze mail or ftp log files instead of web log files,
• You need to analyze load balanced servers log files,
• You want to 'understand' all possible ways to use AWStats...
  Read the AWStats documentation (docs/index.html).

-----> Running OS detected: Linux, BSD or Unix

-----> Check for web server install

Enter full config file path of your Web server.
Example: /etc/httpd/httpd.conf
Example: /usr/local/apache2/conf/httpd.conf
Example: c:\Program files\apache group\apache\conf\httpd.conf
Config file path ('none' to skip web server setup):

/usr/local/httpd/conf/httpd.conf
#填寫網站服務器的完整配置文件路徑。這里的路徑是/usr/local/httpd/conf/httpd.conf
-----> Check and complete web server config file '/usr/local/httpd/conf/httpd.conf'
Warning: You Apache config file contains directives to write 'common' log files
This means that some features can't work (os, browsers and keywords detection).
Do you want me to setup Apache to write 'combined' log files [y/N] ? y
#將日志格式轉換成combined，顯示更為詳細
Add 'Alias /awstatsclasses "/usr/local/awstats/wwwroot/classes/"'
Add 'Alias /awstatscss "/usr/local/awstats/wwwroot/css/"'
Add 'Alias /awstatsicons "/usr/local/awstats/wwwroot/icon/"'
Add 'ScriptAlias /awstats/ "/usr/local/awstats/wwwroot/cgi-bin/"'
Add '<Directory>' directive
AWStats directives added to Apache config file.

-----> Update model config file '/usr/local/awstats/wwwroot/cgi-bin/awstats.model.conf'
File awstats.model.conf updated.

-----> Need to create a new config file ?
Do you want me to build a new AWStats config/profile
file (required if first install) [y/N] ? y
#是否需要創建AWStats的配置文件，當然"y"
-----> Define config file name to create
What is the name of your web site or profile analysis ?
Example: www.mysite.com
Example: demo
Your web site, virtual server or profile name:

www.ly.com #指定要統計的目標網站名稱，虛擬主機名或者自定義配置名，可以同時支持多個站點進行觀測。

-----> Define config file path
In which directory do you plan to store your config file(s) ?
Default: /etc/awstats
Directory path to store config file(s) (Enter for default):

     #默認回車，定義配置文件路徑是在/etc/awstats目錄下

-----> Create config file '/etc/awstats/awstats.www.ly.com.conf'
Config file /etc/awstats/awstats.www.ly.com.conf created.

-----> Restart Web server with '/sbin/service httpd restart'

-----> Add update process inside a scheduler
Sorry, configure.pl does not support automatic add to cron yet.
You can do it manually by adding the following command to your cron:
/usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=www.ly.com
Or if you have several config files and prefer having only one command:
/usr/local/awstats/tools/awstats_updateall.pl now
Press ENTER to continue...

A SIMPLE config file has been created: /etc/awstats/awstats.www.ly.com.conf
You should have a look inside to check and change manually main parameters.
You can then manually update your statistics for 'www.ly.com' with command:

perl awstats.pl -update -config=www.ly.com
You can also read your statistics for 'www.ly.com' with URL:
http://localhost/awstats/awstats.pl?config=www.ly.com #注意訪問awstats的URL

Press ENTER to finish... #默認回車退出

3、修改awstats配置文件

[root@localhost ~]# vi awstats/awstats.www.ly.com.conf //修改程序的主配置文件

LogFile="/usr/local/httpd/logs/access_log" //LogFile用來指定日志文件位置，第50行
DirData="/var/lib/awstats" //220行 手動建立每次抓取的數據存放位置

[root@localhost ~]# mkdir /var/lib/awstats #創建awstats統計數據存放目錄

4.將之前的修改過的日志格式清空一下

[root@localhost ~]#cd /usr/local/httpd/logs/
[root@localhost logs]#rm -f *log #之前日志格式是common，現在使用awstats改為了combined
[root@localhost logs]#service httpd restart #重新生成日志文件

5.采集數據及訪問awstats

[root@localhost ~]#cd /usr/local/awstats/tools/
[root@localhost tools]#chmod +x awstats_updateall.pl
[root@localhost tools]#./awstats_updateall.pl now //手動采集/跟新一次數據

接下來訪問下頁面

再次手動采集

http://192.168.40.15/awstats/awstats.pl?config=www.ly.com

6、跟新手動不方便，借助于計劃任務執行：

[root@localhost tools]# crontab -e #編輯周期性任務計劃

/5 * /usr/local/awstats/tools/awstats_updateall.pl now

crontab -l
service crond status
systemctl enable crond
systemctl list-unit-files | grep crond

7、通過配置頁面自動跳轉優化統計頁面訪問

[root@localhost ~]#vi /usr/local/httpd/htdocs/aw.html #創建跳轉頁面

<html>
<head>
<meta http-equiv=refresh content="0;
url=http://192.168.40.15/awstats/awstats.pl?config=www.ly.com">
</head>
<body></body>
</html>

8、設置awstats網頁訪問認證
[root@localhost ~]# vim /usr/local/httpd/conf/httpd.conf
