insmod loads the given module into the kernel

Linux has many features that come in modules and are loaded into the kernel when needed. This allows the kernel to be leaner, thereby increasing efficiency and retaining greater flexibility. Such loadable modules are usually device drivers.

syntax insmod(option)(parameter) option-f: do not check whether the current kernel version is consistent with the kernel version when the module is compiled, force the module to load; -k: set the module to automatic disassembly; -m: output the loading information of the module; -o: specify the name of the module, you can use the file name of the module file; -p: test whether the module can be loaded correctly into the kernel; -s: record all information in the system log file; -v: display detailed information during execution;-x： Do not export external symbols of the module; -X: Export all external symbols of the module, this is preset. Parameter Kernel Module: Specifies the kernel module file to load.

The instance loads the RAID1 array level module as follows:

[root@localhost boot]# insmod /lib/modules/2.6. 18-8.el5/kernel/drivers/md/raid1.ko [root@localhost boot]# lsmod | grep raid1 raid1 25153 0 From the above display results, it can be seen that RAID1 module has been successfully loaded. Only when loading modules using the insmod command, absolute paths are required to load, and dependencies cannot be resolved automatically when loading.
