nginx+awstats 统计web服务器log的教程: 发布时间：2019-07-26编辑：脚本学堂

默认编译安装的nginx对cgi的支持并不好(所以在编译的时候一般都没打开这个功能)

google了一把。大家都用fastcgi来支持。http://wiki.codemongers.com/NginxSimpleCGI
很多人懒得看英文，我就翻译一下吧。
如果你没有cgi的文件，可以自己建立一个简单的。
只需要如下三行代码就可以了。

复制代码代码如下:

#vi index.cgi
#!/usr/bin/perl

print "Content-type: text/htmlnn";
print "<html><body>Hello, world.</body></html>";

放到web根目录下的cgi-bin目录里面，记得要给它执行权限
接下来是用perl写一个daemon程序来处理cgi文件，幸运的是源代码已经有了。嘿嘿

复制代码代码如下:

#vi cgiwrap-fcgi.pl

#!/usr/bin/perl -w
use FCGI;
use Socket;
use FCGI::ProcManager;
sub shutdown { FCGI::CloseSocket($socket); exit; }
sub restart { FCGI::CloseSocket($socket); &main; }
use sigtrap 'handler', &shutdown, 'normal-signals';
use sigtrap 'handler', &restart, 'HUP';
require 'syscall.ph';
use POSIX qw(setsid);

#&daemonize; we don't daemonize when running under runsv
#this keeps the program alive or something after exec'ing perl scripts
END()   { }
BEGIN() { }
{
    no warnings;
    *CORE::GLOBAL::exit = sub { die "fakeexitnrc=" . shift() . "n"; };
};
eval q{exit};
if ($@) {
    exit unless $@ =~ /^fakeexit/;
}
&main;

sub daemonize() {
    chdir '/' or die "Can't chdir to /: $!";
    defined( my $pid = fork ) or die "Can't fork: $!";
    exit if $pid;
    setsid() or die "Can't start a new session: $!";
    umask 0;
}

sub main {

#$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 ); #use IP sockets
#$socket = FCGI::OpenSocket( "/var/run/nginx/perl_cgi-dispatch.sock", 10 ); #use UNIX sockets - user running this script must have w access to the 'nginx' folder!!
#foreach $item (keys %ENV) { delete $ENV{$item}; }
    $proc_manager = FCGI::ProcManager->new( {n_processes => 5} );
    $socket = FCGI::OpenSocket( "/opt/nginx/fcgi/cgi.sock", 10 )
        ; #use UNIX sockets - user running this script must have w access to the 'nginx' folder!!
    $request =
        FCGI::Request( *STDIN, *STDOUT, *STDERR, %req_params, $socket,
        &FCGI::FAIL_ACCEPT_ON_INTR );
    $proc_manager->pm_manage();
    if ($request) { request_loop() }
    FCGI::CloseSocket($socket);
}

sub request_loop {
while ( $request->Accept() >= 0 ) {
$proc_manager->pm_pre_dispatch();

        #processing any STDIN input from WebServer (for CGI-POST actions)
        $stdin_passthrough = '';
        { no warnings; $req_len = 0 + $req_params{'CONTENT_LENGTH'}; };
        if ( ( $req_params{'REQUEST_METHOD'} eq 'POST' ) && ( $req_len != 0 ) )
        {
            my $bytes_read = 0;
            while ( $bytes_read < $req_len ) {
                my $data = '';
                my $bytes = read( STDIN, $data, ( $req_len - $bytes_read ) );
                last if ( $bytes == 0 || !defined($bytes) );
                $stdin_passthrough .= $data;
                $bytes_read += $bytes;
            }
        }

            print
"Error: No such CGI app - $req_params{SCRIPT_FILENAME} may not exist or is not executable by this process.n";
        }
    }
}

这个文件只需要修改一个地方/opt/nginx/fcgi/cgi.sock，改到你想放的地方，比如/var/run/fcgi.sock 注意要有权限，以便nginix可以正常访问它，如果不知道怎么配置权限
就chmod 777 好了（汗，一个很烂的习惯），正确的做法是将该文件的属主和数组设为nginx的运行用户，
比如nginx用nobody用户运行，则 chown nobody:nobody /var/run/cgi.sock 注意，上层目录也要有执行权限，这样才能访问这个unix socket（访问不到目录，自然不能访问文件了）
这些都做好以后可以启动这个文件了，
#chmod 755 cgiwrap-fcgi.pl
#./cgiwrap-fcgi.pl &
再后台运行。不过这该死的程序居然在终端打印日志，一会调试成功了，可以用
./cgiwrap-fcgi.pl >/dev/null 2>&1 &
这样世界就清净了
如果想保留日志，自己改perl代码吧，不是很难，加上输出文件句柄就可以了。保存到文件中。嘿嘿。
接下来就修改nginx.conf

复制代码代码如下:

location ~ ^/cgi-bin/.*.cgi$ {
        gzip off; #gzip makes scripts feel slower since they have to complete before getting gzipped
        fastcgi_pass unix:/var/run/nginx/cgi.sock;
        fastcgi_index index.cgi;
        fastcgi_param SCRIPT_FILENAME /var/www/cgi-bin$fastcgi_script_name;
        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;

下面这么多其实可以用一个文件来包含起来，不用这么多，看的心乱

复制代码代码如下:

ok,接下来重启nginx
kill -HUP `cat /usr/local/nginx/nginx.pid`
然后我们访问刚才的那个cgi文件，[url]http://XXXXXXXXXX/cgi-bin/index.cgi[/url] 如果看到hello world ，就说明成功了。嘿嘿，就这么简单。

awstats默认的配置中只有IIS和apache的LOG格式，需要我们自定义一下
在/etc/awstats/awstats.mysite.conf里设置log格式如下(默认值是1):
LogFormat="%host %other %logname %time1 %methodurl %code %bytesd %refererquot %uaquot %otherquot"

在nginx中也配置好log格式
log_format wwwlogs '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /var/log/nginx/blog_log.log wwwlogs;

再设置log的轮转

3)新建一个日志回滚,vi /etc/logrotate.d/nginx (路径根据操作系统不同而变化)
内容如下:

复制代码代码如下:

/var/log/nginx {

daily

missingok

rotate 7

compress

delaycompress notifempty

create 644 nginx root sharedscripts

prerotate

/usr/local/awstats/wwwroot/cgi-bin/awstats.pl --config=www.mysite.com -update

endscript

postrotate

if [ -f /usr/local/nginx/nginx.pid ]; then

kill -USR1 `cat /usr/local/nginx/nginx.pid`

fi

endscript

}
