很多PHP搭建的网站都在由apache转向了nginx。nginx的日志信息如何分析呢? 当然你可以自己写一个,但是这里也推荐一款结果信息非常详尽的开源工具——Awstats ,它基于perl编写,它的介绍如下:
AWStats is a free powerful and featureful tool that generates advanced web, streaming, ftp or mail server statistics, graphically. This log analyzer works as a CGI or from command line and shows you all possible information your log contains, in few graphical web pages. It uses a partial information file to be able to process large log files, often and quickly. It can analyze log files from all major server tools like Apache log files (NCSA combined/XLF/ELF log format or common/CLF log format), WebStar, IIS (W3C log format) and a lot of other web, proxy, wap, streaming servers, mail servers and some ftp servers.

第一步,日志的处理。
最好每天分割一下日志,一开始没注意这个工作,结果不久日志文件就上G了,很痛苦。分割日志很简单,首先把日志文件复制到别的地方,然后再通知nginx重新生成日志就可以了。shell脚本如下:
#
!/bin/bash
logs_path
=
"
/nginx/logs/
"
mv ${logs_path}access
.
log
${logs_path}access_$(date
-
d
"
yesterday
"
+
"
%Y%m%d
"
)
.
log
kill
-
USR1 `cat
/
nginx
/
logs
/
nginx
.
pid`
代码中的/nginx/logs指的是nginx的log日志文件所在目录,生成了以昨天日期命名的日志文件。
为了达到每天自动分割的目的,在crontab中加入以下部分:
1
0
*
*
*
sh
/
home
/
zyf
/
sh
/
cut_nginx_log
.
sh
这样就每天的0点1分把nginx日志重命名为日期格式,并重新生成今天的新日志文件。
第二步,Awstats的配置。
日志文件分割好了,接下来就是分析了,也就是Awstats的使用了。
Awstats的配置文件默认会存储在/etc/awstats/目录下,包括你安装时设置的域名如:awstats.www.xxxxke.com.conf。在这个配置文件中修改这个地方:
LogFile
=
"
/nginx/logs/access_%YYYY-0%MM-0%DD-24.log
"
这个意思是要去读取nginx昨天的日志文件,关于后边%YYYY-0%MM-0%DD-24的设置,规则如下:
#
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
第三步,开始分析、生成结果。
最后,可以执行分析了。使用这个命令:
/
usr
/
local
/
awstats
/
wwwroot
/
cgi
-
bin
/
awstats
.
pl
-
update
-
config
=
www
.
xxxxke
.
com
这个命令会把结果生成到/var/lib/awstats 目录下 awstatsXXXX.www.XXXX.com.txt文件。
当然啦,这样看起来不太方便哦,呵呵,可以再用下面的命令来生成html页面,相当漂亮:
perl /usr/local/awstats/tools/awstats_buildstaticpages.pl -update \
-config=www.xxxxoke.com -lang=cn \
-dir=/html/awstats \
-awstatsprog=/usr/local/awstats/wwwroot/cgi-bin/awstats.pl
这样就会在/html/awstats目录下生成很漂漂的分析结果页,很暴力很强大。
第四步,自动化。
要是每天都去服务器上运行几条命令肯定是件令人烦燥的事情,所以呢,linux的世界里有crontab这样的好东东,很简单,下面是我的crontab
