Xcode Server 无法启动

Question

我在使用这个 Xcode 服务器时遇到了困难，已经在上面浪费了好几天时间......我在优胜美地，一切都是最新的。上周一切正常，除了每次我必须重新启动我的 mac mini 服务器时，我必须通过 VNC 登录以重新启动 Xcode 服务器，而且我一直在经历选择 Xcode.app 的痛苦过程。

这停止了工作，当我选择 Xcode.app 时，我有一个无限的等待时间，当点击取消时，他告诉我同意 Xcode 的用户许可......

我找到了重新启动服务器的命令行并得到了结果：

我在使用服务器应用程序 3.2 的 Maverick 上遇到了这个问题，我无法解决，除非它因为这个原因更新到 Yosemite。

Answer 1

经过几个小时的搜索，我终于找到了问题所在。我在控制台的日志中深入挖掘。在 Xcode 服务器问题之前，我发现一些关于 QuickLook 的错误的提及。错误是说 QuickLook 由于缺少 /tmp 而无法启动。我查看并意识到符号链接 /tmp 指向不存在的 /private/tmp。然后我创建了该目录并授予 777 权限。一切都恢复了！

我认为这与我上周试图在 /tmp/mysql.sock 上打开一个套接字的 MySQL 安装有关。

对于有类似问题的人，我的建议是深入查看服务器日志，搜索xcscontrol，然后查看发生了什么样的错误。
