尝试调试/etc/init.d/named，无输出，将> / dev / null替换为/var/log/named.log吗？

而不是修改初始化脚本，而是研究软件已经提供了哪些调试选项。

您尚未指定要使用的Linux发行版。不过，我可以根据CentOS 6提出以下建议：

1：手册页named显示了命名守护程序的以下调试选项：

   -d debug-level
       Set the daemon’s debug level to debug-level. Debugging traces from
       named become more verbose as the debug level increases.

   -g Run the server in the foreground and force all logging to stderr.

2：将这些选项传递给守护程序的正确方法是：修改/etc/sysconfig/named，并在OPTIONS变量中指定需要将哪些命令行选项传递给守护程序。/etc/sysconfig/named在运行named守护程序之前，文件将从init脚本中获取。

查找带有OPTIONS =的行，取消注释，然后对其进行编辑以显示如下：

OPTIONS="-g"

3：现在，使用init脚本启动守护程序；脚本应保留在前台，并且守护程序的输出应出现在窗口中。

这是在我的测试中启用“ -g”选项的效果的示例：

不对OPTIONS进行任何修改：

[user@mycentos6box ~]# /etc/init.d/named start
Starting named:                                            [  OK  ]
[user@mycentos6box ~]# 

根据以上内容修改选项：

[user@mycentos6box ~]# /etc/init.d/named start
