Apache为dav_svn启用dav_svn

Question

要调试一个问题，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。这并不是用于生产的，这也是身份验证也被禁用的原因。

我被dump_io困住了，我的error.log不包含请求/响应。

这是相关的设置。

Dockerfile

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 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>

2000-default.conf(这是默认的，我只添加了LogLevel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>

将这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

在提出请求之后，我希望/var/log/apache2/error.log包含GET /svn/myrepo的全部响应。

经过一夜的睡眠和一些RTFM，我找到了解决办法。

我撒了一些

LogLevel dumpio:trace7

到处都是，而且很管用。

为什么这不是默认的，我无法理解。无论如何，您必须启用/禁用DumpIOInput和DumpIOOutput。

此外，需要将mod_dumpio配置为LogLevel trace7：
