我正在尝试将 mail.aliases 映射添加到我的 NIS/YP 服务器上的 Makefile 中。我已将“mail”添加到要构建的映射列表中，并确保它指向正确的别名文件 (/etc/aliases)。
我遇到的问题是，当我运行 make 时，出现如下“回调超时”错误：
mail.aliases -> “SlaveNisServer”：回调超时
其他地图似乎已成功构建。
有人知道这里可能出了什么问题吗？
答案1
可能是您的从属服务器设置不正确 - 尝试在 SlaveNisServer 上运行 ypinit，并确保 NIS（和 rpcbind）守护程序正在运行：
/usr/lib/yp/ypinit -s MasterNisServer
答案2
谢谢。帮助解决了问题：
# /usr/lib64/yp/ypinit -s nfs1
We will need a few minutes to copy the data from nfs1.

nfs2's NIS data base has been set up.
If there were warnings, please figure out what went wrong, and fix it.
此时，请确保/etc/passwd和/etc/group已被编辑，以便在激活 NIS 时，将使用您刚刚创建的数据库，而不是/etcASCII 文件。
[root@nfs2:/root]
同时运行：服务 ypserv 重新启动 这将更新 ypserv 设置。
答案3
我在 NIS 系统中添加新文件后也遇到了同样的问题。我手动复制了生成的二进制文件，之后它在从属服务器上同步。显然，指出的 ypinit 也重新复制了该文件。
