使用systemctl时无法启动named

我无法在Fedora 18 Raspberry Pi旋转上开始使用systemd命名时遇到麻烦。它开始，然后过一会儿超时，然后失败。如果我手动运行named.service中的命令，则named开始就可以了。我不知道systemctl在寻找什么超时或者在哪里调用它。我已经阅读了systemctl，systemd和其他手册页，并且我将继续进行研究，但是如果有人有任何指点，那就太好了。

systemctl status named.service 输出：

回答。

这是一行：

启动后不可读（尚未？）的PID文件/run/named/named.pid。

（还？）把我扔了。我以为抛出该消息是因为它试图在通过named写入之前读取PID文件，并且由于此后我没有看到错误，所以我认为它最终可以成功读取它。我读英语真傻。实际上，named将pidto 写入到/var/run/named/named.pid从未被systemctl（或systemd）读取的。

更改了PIDFile named.service并启动。喜悦。

systemctl enable named 

之前需要

systemctl start named
