本文介绍如何配置 rc.local 脚本来实现系统的自定义启动任务。管理员可以通过创建并设置该文件为可执行的方式，在系统启动时运行特定的脚本。文章详细解释了设置步骤，包括添加必要的 shebang 行及确保脚本正确结束。
The /etc/rc.d/rc.local local customization script is no longer included by default. Administrators who need this functionality merely have to create this file, make it executable, and it will run on boot. Upgrades are not affected by this change.
# touch /etc/rc.d/rc.local
Is your rc.local executable? if not make it executable
# chmod a+x /etc/rc.d/rc.local
Be also sure to add at the very top of the file the shebang line:
#!/bin/sh
another thing you should be sure of is to add a trailing line like this:
exit 0
because the booting process always expects this script to end successfully and return a 0 exit value.
# touch /etc/rc.d/rc.local

# chmod a+x /etc/rc.d/rc.local
