nginx 日志格式设定，去掉如下行#号
#vim /usr/local/nginx/conf/nginx.conflog_format access '$remote_addr -$remote_user [$time_local] "$request" ''$status $body_bytes_sent"$http_referer" ''"$http_user_agent"$http_x_forwarded_for';access_log log/access.log main;
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_sent：记录发送给客户端文件主体内容大小；
$http_referer：用来记录从哪个页面链接访问过来的；
$http_user_agent：记录客户端浏览器的相关信息；
nginx日志切割脚本
#vim /usr/local/nginx/nginx_log.sh#!/bin/bashlogs_path="/usr/local/nginx/logs/" #设置日志文件存放目录pid_path="/usr/local/nginx/logs/nginx.pid" #设置pid文件mv${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，所有日志文件格式是前一天的日期，如access_20130728.logkill-USR1 `cat${pid_path}` #向nginx主进程发信号重新打开日志 安装和配置awstats
yum方式安装sudo yum -y install awstats如果不能yum安装，请运行sudo rpm -ivh http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm另外安装一下GeoIP，一会可以分析IP的国家yum install GeoIP GeoIP-data GeoIP-devel perl-Geo-IP -y如果安装不成功，可以运行如下方法rpm -ivh https://epel.mirror.angkasa.id/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmyum install mod_geoip GeoIP GeoIP-devel GeoIP-data zlib-devel sudo chown -R sysadmin:sysadmin /var/lib/awstats/sudo chown -R sysadmin:sysadmin /var/www/awstats/
执行tools目录中的awstats_configure.pl配置向导，创建一个新的统计
/usr/share/awstats/tools/awstats_configure.pl
将会有如下一些提示：
-----> Running OS detected: Linux, BSD or UnixWarning: AWStats standard directory on Linux OS is '/usr/local/awstats'.If you want to use standard directory, you should first move all contentof AWStats distribution from current directory:/home/sysadminto standard directory:/usr/local/awstatsAnd then, run configure.pl from this location.Do you want to continue setup from this NON standard directory [yN] ? y-----> Check for web server installEnter full config file path of your Web server.Example: /etc/httpd/httpd.confExample: /usr/local/apache2/conf/httpd.confExample: c:\Program files\apache group\apache\conf\httpd.confConfig file path ('none' to skip web server setup):> none #这里填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 AWStatsscript as a CGI, if you want to build reports dynamically.See AWStats setup documentation (file docs/index.html)-----> Need to create a new config file ?Do you want me to build a new 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 createWhat is the name of your web site or profile analysis ?Example: www.mysite.comExample: demoYour web site, virtual server or profile name:>www.a.com #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 pathIn which directory do you plan to store your config file(s) ?Default: /etc/awstatsDirectory path to store config file(s) (Enter for default):> #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=nginxOr if you have several config files and prefer having only onecommand: /usr/local/awstats/tools/awstats_updateall.pl nowPress 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=nginxYoucan also build static report pages for'nginx' with command:> perl awstats.pl -output=pagetype -config=nginxPressENTER to finish... #回车完成配置文件的创建
默认会生成一个名为awstats.www.a.com.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.www.a.com.conf LogFile="/usr/share/awstats/tools/logresolvemerge.pl /var/log/nginx/access_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，我这里因为要分析多种不同的日志文件，所以采用了*| 的方式
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
默认awstats用于记录数据的目录在：
/var/lib/awstats
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，首先创建一个文件，例：
mkdir /var/www/awstats
生成静态文件：
/usr/share/awstats/tools/awstats_buildstaticpages.pl -update -config=www.a.com -lang=cn -dir=/var/www/awstats -awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl
/usr/share/awstats/tools/awstats_buildstaticpages.pl Awstats静态页面生成工具
-update -config= 更新配置项
-lang=cn 语言为中文
-dir=/var/www/awstats 统计输出结果
-awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl Awstats 日志更新程序路径
修改nginx配置文件，添加日志分析结果站点
server { listen 8080; server_name awstats.a.com; access_log /var/log/nginx/awstats.access_log main; error_log /var/log/nginx/awstats.error_log info; root /var/www/awstats; index index.html; # Restrict access #auth_basic "Restricted"; #auth_basic_user_file /etc/awstats/htpasswd; # Dynamic stats. location ~ ^/cgi-bin/(awredir|awstats)\.pl { gzip off; include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME /usr/share/awstats/wwwroot/cgi-bin/fcgi.php; fastcgi_param X_SCRIPT_FILENAME /usr/share/awstats/wwwroot$fastcgi_script_name; fastcgi_param X_SCRIPT_NAME $fastcgi_script_name; include fastcgi_params; } # Static awstats files: HTML files stored in DOCUMENT_ROOT/awstats/ location /classes/ { alias /usr/share/awstats/wwwroot/classes/; } location /css/ { alias /usr/share/awstats/wwwroot/css/; } location /icon/ { alias /usr/share/awstats/wwwroot/icon/; } location /awstats-icon/ { alias /usr/share/awstats/wwwroot/icon/; } location /js/ { alias /usr/share/awstats/wwwroot/js/; }} 重新加载nginx
sudo nginx -t #检查nginx配置文件是否有误sudo nginx -s reload #加载
添加定时任务，每晚切割，分析nginx日志
