问题描述

我在我的服务器上运行gitweb和gitolite： http://git.jshawl.com/



我无法设置 git-http-backend 以允许匿名克隆。



以下是我的vhosts文件（ /etc/apache2/extra/httpd-vhosts.conf ）的外观：

 < VirtualHost *：80> 
 DocumentRoot/ Users / git / repositories
 ServerName git.jshawl.com 
<目录/ Users / git / repositories>

 SetEnv GIT_HTTP_EXPORT_ALL

 git-（upload | receive）-pack））$\ 
 / usr / libexec / git-core / git-http- backend / $ 1 
 
 ScriptAlias / /Users/git/repositories/gitweb.cgi/





我遵循这里的指示： http://www.kernel.org/pub/software/scm/git/docs/git-http-backend.html ，但我一直在面对与502错误。

我的apache错误日志说： [Fri Aug 24 19:29:32 2012] [error] [client 198.228.200.148] client denied by服务器配置：/ usr / libexec / git-core / git -http-backend



另外，添加所有这一切后，我的gitweb安装（曾经在 http://git.jshawl.com ）



我做错了什么？

解决方案

这里是这个 httpd.conf 中的另一种方法，适用于克隆/推送/但不会调用gitweb.cgi ：



GitWeb用于浏览，而不是用于克隆



（小提取，移除验证详细信息和SSL细节） 

 ＃GitHttp @ PORT_HTTP_HGIT @ 
 Listen @ PORT_HTTP_HGIT @ 
< VirtualHost @FQN @：@ PORT_HTTP_HGIT @> 
 ServerName @ FQN @ 
 ServerAlias @ HOSTNAME @ 
 SetEnv GIT_PROJECT_ROOT @ H @ /存储库
 SetEnv GIT_HTTP_EXPORT_ALL 
 SetEnv GITOLITE_HTTP_HOME @ H @ 
 ScriptAlias / hgit / @ H @ / gitolite / bin / gitolite-shell / 
 SetEnv GIT_HTTP_BACKEND@ H @ / usr / local / apps / git / libexec / git-core / git-http-backend
< FilesMatch \（CGI | SHTML | PHTML | PHP）$。 > 
 SSLOptions + StdEnvVars 
< / FilesMatch> 
< Location / hgit> 
 AddHandler cgi-script cgi 
< / Location> 
< / VirtualHost>

换言之：


  • git-http-backend 被变量 GIT_HTTP_BACKEND 引用，但 you won'如果您使用的是Gitolite V3，那就需要它。

  • gitolite-shell 当您使用 / hgit / 在您的克隆地址中：theat GitoliteV3脚本将检查您是否有权克隆回购，如果是，将调用脚本后面的命令 git-http-backend ： git-receive-pack '（for push）or' git-upload-pack '（用于clone / pull / fetch），直接从git源文件本身 http-backend.c 。


所以： 

  git clone https：// yourServer / hgit / yourRep o

会调用gitolite，它会调用' git-receive-pack '或' git-upload-pack '。

它将首先通过调用 sub http_simulate_ssh_connection（） 

  sub http_simulate_ssh_connection {
＃这些模式表示正常的git使用情况;请参阅
＃http-backend.c中的services []，了解我如何得到它。另请注意，信息已过载; 
＃git使用info / refs ...，而gitolite使用info或info？...。所以
＃在
下面的列表中有一个/，如果（$ ENV {PATH_INFO} =〜m（^ /（。*）/（HEAD $ | info / refs $ | objects / | git  - （?: upload | receive）-pack $）））{
 my $ repo = $ 1; 
 my $ verb =（$ ENV {REQUEST_URI} =〜/ git-receive-pack /）？ 'git-receive-pack'：'git-upload-pack'; 
 $ ENV {SSH_ORIGINAL_COMMAND} =$ verb'$ repo'; 
} else {
＃这是我们的自定义命令之一;因为adc功能
 my（$ verb）=（$ ENV {PATH_INFO} =〜m（^ /（\S +）））; 
 my $ args = $ ENV {QUERY_STRING}; 
 $ args =〜s / \ + / / g; 
 $ args =〜s /％（[0-9A-Fa-f] {2}）/ chr（hex（$ 1））/ eg; 
 $ ENV {SSH_ORIGINAL_COMMAND} = $ verb; 
 $ ENV {SSH_ORIGINAL_COMMAND}。=$ argsif $ args; 
 http_print_headers（）; ＃为最终输出做准备！ 
} 
 $ ENV {SSH_CONNECTION} =$ ENV {REMOTE_ADDR} $ ENV {REMOTE_PORT} $ ENV {SERVER_ADDR} $ ENV {SERVER_PORT}; 
}


I'm running gitweb and gitolite on my server: http://git.jshawl.com/

I'm having trouble setting up the git-http-backend to allow anonymous cloning.

Here's what my vhosts file (/etc/apache2/extra/httpd-vhosts.conf) looks like: 

<VirtualHost *:80>
DocumentRoot "/Users/git/repositories"
ServerName git.jshawl.com
 <Directory "/Users/git/repositories">
    Options ExecCGI +FollowSymLinks +SymLinksIfOwnerMatch
    AllowOverride All
    order allow,deny
    Allow from all
    AddHandler cgi-script cgi
    DirectoryIndex gitweb.cgi
</Directory>

<LocationMatch "^/.*/git-receive-pack$">
    AuthType Basic
    AuthName "Git Access"
    Require group committers
</LocationMatch

SetEnv GIT_PROJECT_ROOT /Users/git/repositories
SetEnv GIT_HTTP_EXPORT_ALL
ScriptAliasMatch \
    "(?x)^/(.*/(HEAD | \
        info/refs | \
            objects/(info/[^/]+ | \
                [0-9a-f]{2}/[0-9a-f]{38} | \
                    pack/pack-[0-9a-f]{40}\.(pack|idx)) | \
            git-(upload|receive)-pack))$" \
    /usr/libexec/git-core/git-http-backend/$1

ScriptAlias / /Users/git/repositories/gitweb.cgi/

`

I followed the directions here: http://www.kernel.org/pub/software/scm/git/docs/git-http-backend.html, but am consistently confronted with that 502 error.

My apache error log says: [Fri Aug 24 19:29:32 2012] [error] [client 198.228.200.148] client denied by server configuration: /usr/libexec/git-core/git-http-backend

Also, adding all of this has taken down my gitweb installation (which used to be at http://git.jshawl.com)

What am I doing wrong?

解决方案

Here is another approach in this httpd.conf which works well for cloning/pushing/pulling, but it doesn't call gitweb.cgi:

GitWeb is for browsing, not for cloning

(small extract, removing Auth details, and SSL details)

# GitHttp on @PORT_HTTP_HGIT@
Listen @PORT_HTTP_HGIT@
<VirtualHost @FQN@:@PORT_HTTP_HGIT@>
  ServerName @FQN@
  ServerAlias @HOSTNAME@
  SetEnv GIT_PROJECT_ROOT @H@/repositories
  SetEnv GIT_HTTP_EXPORT_ALL
  SetEnv GITOLITE_HTTP_HOME @H@
  ScriptAlias /hgit/ @H@/gitolite/bin/gitolite-shell/
  SetEnv GIT_HTTP_BACKEND "@H@/usr/local/apps/git/libexec/git-core/git-http-backend"
  <FilesMatch "\.(cgi|shtml|phtml|php)$">
    SSLOptions +StdEnvVars
  </FilesMatch>
  <Location /hgit>
    AddHandler cgi-script cgi
  </Location>
</VirtualHost>

In other words:

  • git-http-backend is referenced by the variable GIT_HTTP_BACKEND, but you won't need it if you are using Gitolite V3.
  • gitolite-shell is called when you are using /hgit/ in your cloning address: theat GitoliteV3 script will check if you have the right to clone the repo, and if yes, will call the commands behind the script git-http-backend: 'git-receive-pack' (for push) or 'git-upload-pack' (for clone/pull/fetch), straight from the git source itself http-backend.c.

So:

git clone https://yourServer/hgit/yourRepo

Will call gitolite, which will call 'git-receive-pack' or 'git-upload-pack'.
It will first analyze the http request by calling sub http_simulate_ssh_connection()

sub http_simulate_ssh_connection {
    # these patterns indicate normal git usage; see "services[]" in
    # http-backend.c for how I got that. Also note that "info" is overloaded;
    # git uses "info/refs...", while gitolite uses "info" or "info?...". So
    # there's a "/" after info in the list below
    if ( $ENV{PATH_INFO} =~ m(^/(.*)/(HEAD$|info/refs$|objects/|git-(?:upload|receive)-pack$)) ) {
        my $repo = $1;
        my $verb = ( $ENV{REQUEST_URI} =~ /git-receive-pack/ ) ? 'git-receive-pack' : 'git-upload-pack';
        $ENV{SSH_ORIGINAL_COMMAND} = "$verb '$repo'";
    } else {
        # this is one of our custom commands; could be anything really,
        # because of the adc feature
        my ($verb) = ( $ENV{PATH_INFO} =~ m(^/(\S+)) );
        my $args = $ENV{QUERY_STRING};
        $args =~ s/\+/ /g;
        $args =~ s/%([0-9A-Fa-f]{2})/chr(hex($1))/eg;
        $ENV{SSH_ORIGINAL_COMMAND} = $verb;
        $ENV{SSH_ORIGINAL_COMMAND} .= " $args" if $args;
        http_print_headers(); # in preparation for the eventual output!
    }
    $ENV{SSH_CONNECTION} = "$ENV{REMOTE_ADDR} $ENV{REMOTE_PORT} $ENV{SERVER_ADDR} $ENV{SERVER_PORT}";
}
