Do I have to place the command to be started on/etc/rc. Local that will start automatically?

 Today, the supervisor asked to modify the routing policy and finally added the commands required for starting the system to/etc/rc. local, the reboot result command was not executed, and later the supervisor reminded me to know that the boot command was added to/etc/rc. local may not start automatically at startup. First, let's take a look at this principle:

By default, the file loaded at startup is usually/etc/rc. d/RC. local, why is it? This is the same as/etc/rc. A file under D is related to/etc/rc. d/rcX. d/s99local is linked to/etc/rc. d/RC. local, where X is the boot level

Take a look at the current Boot level: runlevel

Let's take a look.File Attributes of/etc/rc. d/rc3.d/s99local:

/Etc/rc. Local can also achieve self-startup effect?

The answer is If/etc/rc. local is/etc/rc. d/RC. the local connection file can be used. If it is not, it cannot be used. If it must be in/etc/rc. how does the local command enable the command in the file?

Delete the original/etc/rc. Local and connect to/etc/rc. d/rc. Local.

Ln-S/etc/rc. d/rc. Local/etc/rc. Local
