Nginx日志分析awstats
Awstats功能及简介：
AWStats是在Sourceforge上发展很快的一个基于Perl的WEB日志分析工具。
它可以统计您站点的如下信息：
访问量（UV），访问次数，页面浏览量（PV），点击数，数据流量等
精确到每月、每日、每小时的数据
访问者国家
访问者IP
Robots/Spiders的统计
访客持续时间
对不同Files type的统计信息
Pages-URL的统计
访客操作系统浏览器等信息
其它信息（搜索关键字等等）
一、修改nginx日志格式（因为不修改日志格式awstats无法做日志分析）：
access_log /usr/local/nginx/logs/access.log;
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
参数说明：
$remote_addr 与$http_x_forwarded_for 用以记录客户端的ip地址；
$remote_user ：用来记录客户端用户名称；
$time_local ：用来记录访问时间与时区；
$request ：用来记录请求的url与http协议；
$status ：用来记录请求状态；成功是200，
$body_bytes_s ent ：记录发送给客户端文件主体内容大小；
$http_referer ：用来记录从那个页面链接访问过来的；
$http_user_agent ：记录客户毒啊浏览器的相关信息；
二、nginx日志切割：
脚本:
Vim nginx_log.sh
#!/bin/bash
logs_path="/usr/local/nginx/logs/" #设置日志文件存放目录
pid_path="/usr/local/nginx/logs/nginx.pid" #设置pid文件
mv ${logs_path}access.log ${logs_path}access_$(date -d "yesterday" +"%Y%m%d").log
#重命名日志文件，将access.log切割为昨天的日志文件，因为要在每天零点切割，所有的日志格式是前一天的日期，如access_20150916.log
kill -USR1 `cat ${pid_path}` #向nginx主进程发信号重新打开日志
三、安装awstats：
wget http://awstats.sourceforge.net/files/awstats-7.0.tar.gz
tar -xvf awstats-7.0.tar.gz
mv awstats-7.0 /usr/local/awstats
chown -R root:root /usr/local/awstats
chmod -R =rwX /usr/local/awstats
chmod +x /usr/local/awstats/tools/*.pl
chmod +x /usr/local/awstats/wwwroot/cgi-bin/*.pl
执行tools 目录中的awstats_configure.pl 配置向导，创建一个新的统计
cd /usr/local/awstats/tools
./awstats_configure.pl
将会有如下一些提示：
----->Running OS detected: Linux, BSD orUnix
----->Check forweb server install
Enterfull 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):
>none#这里添none并回车，因为我们没有使用apache
回车之后下一个选项：
Yourweb server config file(s) could not be found.
Youwill need to setup your web server manually to declare AWStats
script as a CGI, ifyou want tobuild reports dynamically. See AWStats setup documentation (file docs/index.html)
----->Update model config file '/usr/local/awstats/wwwroot/cgi-bin/awstats.model.conf' File awstats.model.conf updated.
----->Need to create a newconfig file ? Do you want me to build anew AWStats config/profilefile (required if first install) [y/N] ? y #这里选Y，创建一个新的配置文件
----->Define config file name to create
What isthe name of your web site or profile analysis ?
Example: www.mysite.com
Example: demo
Yourweb site, virtualserver or profile name:
>nginx#这里输入你要分析的域名，或是随便一个你易记的配置名并回车
----->Define config file path In which directory do you plan to store your config file(s) ?
Default: /etc/awstats
Directorypath to store config file(s) (Enter fordefault):
> #直接回车，定义你的配置文件存放的路径，使用默认路径/etc/awstats
----->Create config file '/etc/awstats/awstats.nginx.conf'
Configfile /etc/awstats/awstats.nginx.conf created.
----->Add updateprocess inside a scheduler Sorry, configure.pl does not support automatic addto cron yet.
You can do it manually by adding the following command to yourcron: /usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=nginx
Or ifyou have several config files and prefer having only onecommand: /usr/local/awstats/tools/awstats_updateall.pl now
Press ENTER to continue...#按回车继续
A SIMPLE config file has been created: /etc/awstats/awstats.nginx.conf You should have a lookinside to check and change manually main parameters.
Youcan then manually update your statistics for'yuyuanchun.com'withcommand: > perl awstats.pl -update -config=nginx
Youcan also build staticreport pages for'nginx'with command:> perl awstats.pl -output=pagetype -config=nginx
PressENTER to finish... #回车完成配置文件的创建
默认会生成一个名为awstats.nginx.conf配置文件在/etc/awstats/目录下，修改该配置文件的日志位置
vim /etc/awstats/awstats.nginx.conf
LogFile="/usr/local/nginx/logs/access_%YYYY-0%MM-0%DD-24.log"
这里是对应上面Nginx日志切割所生成的目录存放位置，注意awstats的年月日格式，-24表示昨天的日志，-0表示当前的
分析的执行顺序是：
Nginx 产生日志 –> 日志切割 –> Nginx 继续产生日志 –> 另存切割日志–> 交由Awstats统计 –> 生成结果
日志说明
# "LogFile" contains the web, ftp or mail server logfile to analyze.
#You can also use tags inthisfilename if you need a dynamic file name
#depending on date or time (Replacement is made by AWStats at the beginning
# ofits execution). This is available tags :
# %YYYY-n is replaced with 4 digits year we were n hours ago
# %YY-n is replaced with 2 digits year we were n hours ago
# %MM-n is replaced with 2 digits month we were n hours ago
# %MO-n isreplaced with 3letters month we were n hours ago
# %DD-n is replaced with day we were n hours ago
# %HH-n isreplaced with hour we were n hours ago
# %NS-n isreplaced with number of seconds at 00:00since 1970
# %WM-n is replaced with the week number in month (1-5)
# %Wm-n isreplaced with the week number in month (0-4)
# %WY-n is replaced with the week number in year (01-52)
# %Wy-n is replaced with the week number in year (00-51)
# %DW-n is replaced with the day number in week (1-7, 1=sunday)
# use n=24if you need (1-7, 1=monday)
# %Dw-n isreplaced with the day number inweek (0-6, 0=sunday)
# use n=24if you need (0-6, 0=monday)
# Use 0for n if you need current year, month, day, hour...
n表示时间间隔，我这里就是分析距离当前今天24小时前（昨日）的日志，改成48就是前两天的日志
创建一个awstats用于记录数据的目录
mkdir -p /var/lib/awstats
运行awstats的wwwroot目录中的awstats.pl来测试一下
perl /usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=chen
出现以下结果说明正常：
Create/Update database for config "/etc/awstats/awstats.chen.conf" by AWStats version 7.3 (build 20140126)
From data in log file "/usr/local/nginx/logs/access_20150916.log"...
Phase 1 : First bypass old records, searching new record...

Found 1201 already parsed records.
Parsed lines in file: 0

Found 0 blank records,

Nginx对perl支持并不好，所以在這里用awstats的工具将统计结果生成静态文件：
首先在wwwroot目录下创建一个文件夹：
Mkdir -p /home/www/awstats
生成静态文件：
perl /usr/local/awstats/tools/awstats_buildstaticpages.pl -update -config=chen -lang=cn -dir=/home/www/awstats -awstatsprog=/usr/local/awstats/wwwroot/cgi-bin/awstats.pl
运行脚本出现以下结果说明正确：
Launch update process : "/usr/local/awstats/wwwroot/cgi-bin/awstats.pl" -config=chen -update -configdir=
Build main page: "/usr/local/awstats/wwwroot/cgi-bin/awstats.pl" -config=chen -staticlinks -lang=cn -output

-update -config=nginx 更新配置项
-lang=cn 语言为中文
-dir=/home/www/awstats 统计结果输出目录
-awstatsprog=/usr/local/awstats/wwwroot/cgi-bin/awstats.pl Awstats 日志更新程序路径
修改nginx配置文件，添加日志结果分析站点：
用到apache自带的工具htpasswd：
Yum install httpd-tools -y
Htpasswd -cd admin.pass admin
修改nginx配置文件：
#awstats.conf
server {
listen 85;
server_name localhost;
index index.html index.htm index.php default.html default.htm default.php;
root /home/www/awstats;
location ~ ^/awstats/ {
root /home/www/awstats;
index index.html;
access_log off;
error_log off;
charset gb2312;
auth_basic "admin";
auth_basic_user_file admin.pass;
}
location ~ ^/icon/ {
root /usr/local/awstats/wwwroot;
index index.html;
access_log off;
error_log off;
}
autoindex on;
access_log off;
}
重新加载nginx
ln -s /usr/local/nginx/sbin/nginx /usr/bin/
nginx –t #检查nginx配置文件是否有错误
nginx –s reload #加载
添加定时任务：
Vim /usr/local/nginx/awstats.sh
#!/bin/bash
/usr/bin/sh /usr/local/nginx/nginx_log.sh
/usr/bin/perl /usr/local/awstats/tools/awstats_buildstaticpages.pl -update -config=chen -lang=cn -dir=/home/www/awstats -awstatsprog=/usr/local/awstats/wwwroot/cgi-bin/awstats.pl
Chmod +X /usr/local/nginx/awstats.sh
Crontab -u root -e
01 00 * * * /usr/bin/sh /usr/local/nginx/awstats.sh
访问：http://192.168.1.201:85就可以看到统计结果静态页面了
