我尝试在 /etc/init.d/S98 脚本中添加一些路由，但无法 ping 通网关 IP，因此路由添加失败。但是，一旦执行了所有 S98 脚本，我就能够 ping IP 并添加路由。以下是 S98 脚本执行期间捕获的日志。您能否帮助我了解我在初始化脚本（/etc/rc3.d/S98）执行期间是否遗漏了某些内容。

答案1
初始化脚本按照其中的编号顺序运行：
S01第一
S10第十号
...
S90九十
这样做是为了让您可以在服务中堆叠依赖项，就像S85httpd依赖项一样S10network。如果没有依赖关系，例如 withS08ip6tables和S08iptables，则运行顺序并不重要。
因此，如果您对已运行有依赖性S98（如此处所示），则可以将该服务放入S99.
就我个人而言，除非有充分的理由，否则我会在网络脚本通常运行的范围之后（即S20或 之后S30）对脚本重新编号，具体取决于安装的内容。
编辑：您可能希望从自定义解决方案更改为使用实现绑定的通用方法。Linux Bond / 将多个网络接口 (NIC) 组合为一个接口，并阅读极其缓慢或没有失败的链接检测如果您仍然遇到类似的问题。
答案2
检查已为端口打开 portfast 的交换机。没有 portfast 意味着交换机在转发数据包之前将等待 30 秒。
接口 FastEthernet1
生成树 portfast
