我正在构建一个网络服务器来托管多个网站。除了邮件服务器，我一切正常。我正在使用 linode 来托管我的 vps，并且我一直在学习他们的教程。仅供引用，我使用的是 Ubuntu 11.10。

这是我一直关注的链接，http://library.linode.com/email/postfix/dovecot-mysql-ubuntu-10.04-lucid .我到了它告诉我重新启动 dovecot 的部分，所以我尝试了“service dovecot restart”。但后来我得到这个“重启:未知实例:”。我以 root 身份登录，所以我没有使用 sudo。

因为这不起作用，我尝试了“/etc/init.d/dovecot restart”，我得到了“dovecot start/running, process 4760”。所以我尝试“/etc/init.d/dovecot status”，我得到“dovecot stop/waiting”。

所以我尝试了“service dovecot start”，我得到了“dovecot start/running, process 4781”。所以我尝试获取状态，所以我厌倦了“服务鸽舍状态”并获得了“鸽舍停止/等待”

然后我厌倦了“/etc/init.d/dovecot start”，我得到了“dovecot start/running, process 4794”。所以我厌倦了获得状态，所以我厌倦了“/etc/init.d/dovecot status”并获得了“dovecot stop/waiting”

只是为了好玩和咯咯地笑，我厌倦了终止进程，我使用了在执行“service dovecot start”时获得的 PID，这是命令“kill -9 4444”，我得到了这个“bash:kill: (4805) - 没有这样的过程”

我做错了什么吗？

最佳答案

作为一般提示，尝试直接在前台运行 dovecot:

鸽舍-F

原因是前台经常会直接向控制台输出加载错误消息，这通常可以让您快速跟踪通常不会记录的错误(例如配置解析错误)。
