为了Awstats给Nginx添加FastCGI方式的Perl支持

有个应用(awstats)需要Perl脚本支持,但是用的Nginx服务器,对Perl支持不好,于是通过FastCGI方式来使用Perl。

首先安装Perl的FCGI模块

  1. wget http://www.cpan.org/modules/by-module/FCGI/FCGI-0.67.tar.gz
  2. tar -zxvf FCGI-0.67.tar.gz
  3. cd FCGI-0.67
  4. perl Makefile.PL
  5. make && make install

还可以使用如下方法安装:

perl -MCPAN -e 'install FCGI'

安装FCGI-ProcManager

  1. wget http://search.cpan.org/CPAN/authors/id/G/GB/GBJK/FCGI-ProcManager-0.18.tar.gz
  2. tar -xzxf FCGI-ProcManager-0.18.tar.gz
  3. cd FCGI-ProcManager-0.18
  4. perl Makefile.PL
  5. make
  6. make install

Perl的FastCGI启动脚本

参考这篇文章 http://bbs.chinaunix.net/archiver/?tid-1224968.html

vi fcgi_perl
  1. #!/usr/bin/perl -w
  2. use FCGI;
  3. use Socket;
  4. use FCGI::ProcManager;
  5. sub shutdown { FCGI::CloseSocket($socket); exit; }
  6. sub restart { FCGI::CloseSocket($socket); &main; }
  7. use sigtrap 'handler', \&shutdown, 'normal-signals';
  8. use sigtrap 'handler', \&restart, 'HUP';
  9. require 'syscall.ph';
  10. use POSIX qw(setsid);
  11.  
  12. #&daemonize; we don't daemonize when running under runsv

  164.

  172. "Error: No such CGI app – $req_params{SCRIPT_FILENAME} may not exist or is not executable by this process.\n";
  173. }
  174. }
  175. }

再设置启动的脚本

vi startfcgiperl
  1. export FCGI_SOCKET_PATH="/tmp/perl_fcgi.socket"
  2. export FCGI_NPROCESSES=4
  3. ./fcgi_perl &

为Nginx添加FastCGI的Perl支持

编辑 nginx.conf 脚本,添加如下内容

location ~* .*\.pl$
{
include awstats.conf;
}
location /awstatsicon/
{
   alias /var/www/awstats-6.8/wwwroot/icon/;
}
vi awstats.conf
fastcgi_pass unix:/tmp/perl_fcgi.socket;
fastcgi_index awstats.pl;
#fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
#fastcgi_param SCRIPT_FILENAME /var/www/awstats-6.8/wwwroot/cgi-bin$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME /var/www/awstats-6.8/wwwroot/cgi-bin/awstats.pl;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_read_timeout 60;

配置Awstats

运行 /var/www/awstats-6.8/tools/awstats_configure.pl 设置好一些变量

mkdir -p /etc/awstats
cp /var/www/awstats-6.8/wwwroot/awstats.model.conf /etc/awstats/awstats.my.site.com.conf

使用 vi /etc/awstats.my.site.com.conf 进行一些参数修改,设置icon目录,DirData数据存放目录,来源log日志文件路径等
使用 /var/www/awstats-6.8/tool/awstats_updateall.pl now -awstatsprog=/var/www/awstats-6.8/wwwroot/cgi-bin/awstats.pl 命令进行初始数据更新
使用 http://my.site.com/awstats.pl 查看数据

后续

将 ./awstats_updateall.pl now -awstatsprog=/var/www/awstats-6.8/wwwroot/cgi-bin/awstats.pl 放到crontab 中做定时更新,可以做一个脚本和日志文件的处理一起做。

碰到问题
在使用unix socket时,碰到两个问题
1.写socket的目录没有写权限,添加上解决
2.nginx连不上socket, 看日志提示没有权限,在创建了socket后添加一句
chmod 0777, $ENV{FCGI_SOCKET_PATH};
问题解决。

遗留对awstats.pl访问密码限制问题尚未解决好。
解决 在 nginx 中按如下配置方式

location /awstats {
  root /var/www/awstats-6.8/;
  include awstats.conf;
  auth_basic "awstats";
  auth_basic_user_file /var/www/.passwd;
}

其中 将 awstats-6.8 目录下的 wwwroot 修改为 awstats, /var/www/.passwd 为访问目录要用来验证的账号密码文件,用apache的提供的工具htpasswd制作而成

    有两点疑问:
    1.
    vi startfcgiperlexport FCGI_SOCKET_PATH=”/tmp/perl_fcgi.socket”
    export FCGI_NPROCESSES=4
    ./fcgi_perl &

    这里fcgi_perl会输出到到控制台上.
    我使用1>/dev/null 2>&1 解决
    2.
    你的awstats能显示图片吗? 怎么解决的?

    sunny Reply:

    你可以尝试修改awstats.model.conf 中的 DirIcons路径设置,在配合Web服务器中的路径设置,可以达到显示图片目的

    我是按awstats官方文档将icon复制到了根目录

    就是在浏览器地址栏里:像这样的链接

    http://sitename.com/xxx.pl?name=xxx&status=yyy&k=0

    我试了一下,不加后面那些get的参数是没问题的,但是加上了就不行了。
