Awstats分析Nginx日志
1.nginx日志格式设定
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；
2.nginx日志切割脚本
#!/bin/bash logs_path="/home/wwwlogs/" #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切割为每天的日志文件如access_20130728.log kill -USR1 `cat ${pid_path}` #向nginx主进程发信号重新打开日志
添加定时任务，每晚00:00切割，crontab -e
0 0 * * * bash /usr/local/nginx/nginx_log.sh
3.安装和配置awstats
wget http://awstats.sourceforge.net/files/awstats-7.0.tar.gz tar -zxvf 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 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): >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：
Your web server config file(s) could not be found. You will need to setup your web server manually to declare AWStats script as a CGI, if you want to build 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 new config file ? Do you want me to build a new AWStats config/profilefile (required if first install) [y/N] ?
这里选Y，创建一个新的配置文件
-----> 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: >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
接下来要定义你的配置文件存放的路径，可用默认
-----> 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): > #直接回车，使用默认路径/etc/awstats
回车后的提示
-----> Create config file '/etc/awstats/awstats.nginx.conf' Config file /etc/awstats/awstats.nginx.conf created. -----> 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=nginx 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...#按回车继续 A SIMPLE config file has been created: /etc/awstats/awstats.nginx.conf You should have a look inside to check and change manually main parameters. You can then manually update your statistics for 'yuyuanchun.com' with command: > perl awstats.pl -update -config=nginx You can also build static report pages for 'nginx' with command: > perl awstats.pl -output=pagetype -config=nginx Press ENTER 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
vi /etc/awstats/awstats.nginx.conf LogFile="/home/wwwlogs/access_%YYYY-0%MM-0%DD-24.log"
日志说明
# "LogFile" contains the web, ftp or mail server log file to analyze. # You can also use tags in this filename if you need a dynamic file name # depending on date or time (Replacement is made by AWStats at the beginning # of its 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 is replaced with 3 letters month we were n hours ago # %DD-n is replaced with day we were n hours ago # %HH-n is replaced with hour we were n hours ago # %NS-n is replaced with number of seconds at 00:00 since 1970 # %WM-n is replaced with the week number in month (1-5) # %Wm-n is replaced 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=24 if you need (1-7, 1=monday) # %Dw-n is replaced with the day number in week (0-6, 0=sunday) # use n=24 if you need (0-6, 0=monday) # Use 0 for 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
然后运行awstats的wwwroot目录中的awatsts.pl来测试一下
/usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=nginx
如果看到类似下面的提示就说明配置文件都正确了
Create/Update database for config "/etc/awstats/awstats.nginx.conf" by AWStats version 7.0 (build 1.964) From data in log file "/home/wwwlogs/access.log_20130727"... Phase 1 : First bypass old records, searching new record... Direct access after last parsed record (after line 43260) Jumped lines in file: 43260 Found 43260 already parsed records. Parsed lines in file: 0 Found 0 dropped records, Found 0 comments, Found 0 blank records, Found 0 corrupted records, Found 0 old records, Found 0 new qualified records
4.Nginx 对 Perl 支持并不好，所以这里利用 awstats 的工具将统计的结果生成静态文件
首先在 webroot 目录下创建一个文件夹。例：/home/www/awstats
mkdir -p /home/www/awstats/nginx
写一个脚本，定期执行让 Awstats 把静态页面生成到该目录中，vi /usr/local/nginx/sbin/awstats.sh
/usr/local/awstats/tools/awstats_buildstaticpages.pl -update \ -config=nginx -lang=cn -dir=/home/www/awstats/nginx \ -awstatsprog=/usr/local/awstats/wwwroot/cgi-bin/awstats.pl
/usr/local/awstats/tools/awstats_buildstaticpages.pl Awstats 静态页面生成工具
-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
添加脚本执行权限
chmod +x /usr/local/nginx/sbin/awstats.sh
运行脚本如果出现生成一堆网页类似
Launch update process : "/usr/local/awstats/wwwroot/cgi-bin/awstats.pl" -config=nginx -update -configdir= ...... Build keywords page: "/usr/local/awstats/wwwroot/cgi-bin/awstats.pl" -config=nginx -staticlinks -lang=cn -output=keywords Build errors404 page: "/usr/local/awstats/wwwroot/cgi-bin/awstats.pl" -config=nginx -staticlinks -lang=cn -output=errors404 20 files built. Main HTML page is 'awstats.nginx.html'.
则说明成功了，接下来就可以加入定时任务了crontab -e
00 1 * * * /usr/lcoal/nginx/sbin/awstats.sh #每天凌晨1:00执行
5.修改nginx配置文件，添加日志分析结果站点
server { listen 80; server_name 192.168.75.28; index index.html index.htm index.php default.html default.htm default.php; root /home/wwwroot/awstats; location ^~ /icon/ { root /usr/local/awstats/wwwroot; index index.html; access_log off; } autoindex on; access_log off; }
这样访问http://192.168.75.28就可以看到统计结果静态页面了。
