最近，我在我的 Linux 机器上配置了 subversion edge。安装过程非常顺利（按照此链接中的说明进行安装）[http://www.collab.net/lightbox/download_info/61/34]）并且我能够登录到 csvn 控制台，访问和创建 subversion 存储库。
重启机器后，我只能登录 csvn 控制台，状态页面显示 Subversion 服务器已关闭。当我单击“开始”按钮时，显示一条错误消息，提示“启动 Subversion 服务器时出现问题！”。当我检查服务器错误日志时，我得到的 console.log 为：

我谷歌了一下，发现很多人说这是由于用户权限、所有权等原因。我已经完成了所有步骤，但尝试失败了。我期望有一个可靠的解决方案。请为我提供一个解决方案。
答案1
Apache 进程拒绝启动，因为/opt/csvn/data/conf/csvn_main_httpd.conf第 16 行的配置要求 Web 服务器以 root 身份启动。这不是一件好事；错误消息明确表示，它不会使用此配置启动。
从应用程序的自述文件来看，它听起来像是尝试在运行启动命令的用户下启动；
5. Start the server. Be sure that you are logged in as your own userid and not running as root.
..也许它还csvn_main_httpd.conf用正在运行的用户信息填充文件？尝试以其他用户身份启动它。
或者，我建议只使用 Apache +mod_dav_svn来为您的 SVN 存储库提供服务。使用 jetty 服务启动 Apache 服务似乎不必要地复杂。
答案2
克服这种情况的一个简单方法是，不要安装 subversion edge，只使用启动服务器/csvn/bin/csvn start。在大多数情况下，在使用 root 帐户安装 csvn 期间会发生此错误。这会以某种方式更改 conf 文件的 UID。
