Apache 为 dav_svn 启用 dump_io

Question

要调试我遇到的问题，我需要一个 Apache + Subversion 服务器，它将所有请求和响应转储到一个日志文件中。这不适用于生产，这就是身份验证也被禁用的原因。

我被 dump_io 困住了，我的 error.log 不包含 requests/responses。

这是相关设置。

Docker 文件

FROM ubuntu:18.04

RUN apt-get update
RUN apt-get install -y apache2
RUN apt-get install -y subversion libapache2-mod-svn libsvn-dev
RUN apt-get install -y less nano
RUN a2enmod dav
RUN a2enmod dav_svn
RUN a2enmod dump_io
RUN printf "DumpIOInput On\nDumpIOOutput On\nLogLevel debug" >> /etc/apache2/apache2.conf
RUN service apache2 restart

COPY dav_svn.conf /etc/apache2/mods-enabled/dav_svn.conf
COPY 000-default.conf /etc/apache2/sites-enabled/000-default.conf

RUN mkdir -p /var/local/svn
RUN svnadmin create /var/local/svn/myrepo
RUN chown -R www-data:www-data /var/local/svn
RUN chmod -R 775 /var/local/svn

EXPOSE 80

CMD ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]

dav_svn.conf

<Location /svn/>
  DAV svn
  DavDepthInfinity on

  SVNParentPath /var/local/svn/

  Satisfy Any
  Allow from all
  DirectorySlash Off

  LogLevel debug
</Location>

000-default.conf（这是默认的，我只加了LogLevel这一行）

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn
        LogLevel debug

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

将三个文件放在一个文件夹中

docker build -t svn-server .
docker run -it -p 3570:80 --rm svn-server
curl http://localhost:3570/svn/myrepo

发出请求后，我希望 /var/log/apache2/error.log 包含 GET /svn/myrepo 的完整响应。

经过一夜的睡眠和一些 RTFM，我找到了解决方案。

我撒了一些

LogLevel dumpio:trace7

一切顺利。

我不明白为什么这不是默认设置。无论如何，你必须 enable/disable DumpIOInput 和 DumpIOOutput。

Additionally, mod_dumpio needs to be configured to LogLevel trace7:
