rc.local没有文件的情况下，如何设置开机启动
# ls /etc/rc.local
ls: 无法访问'/etc/rc.local': 没有那个文件或目录

这种情况下，需要按照下面的配置，使其生效

创建rc.local
# touch /etc/rc.local

# chmod +x /etc/rc.local

添加开机自启执行的命令
# vi /etc/rc.local
#!/bin/bash -e
echo 666 > /tmp/test.txt ## 随便创建一个文件，作为验证文件。

查看rc-local进程状态
# systemctl  status rc-local
● rc-local.service - /etc/rc.local Compatibility
Loaded: loaded (/lib/systemd/system/rc-local.service; static; vendor preset: enabled)
  Drop-In: /usr/lib/systemd/system/rc-local.service.d
         └─debian.conf
Active: inactive (dead)
   Docs: man:systemd-rc-local-generator(8)

## 启动rc.local
# systemctl start rc-local
# systemctl status rc-local
● rc-local.service - /etc/rc.local Compatibility
Loaded: loaded (/lib/systemd/system/rc-local.service; static; vendor preset: enabled)

尝试重启（生产慎用）
# reboot

验证
# cat /tmp/test.txt
666
