文章介绍了在DebianGNU/Linux10系统中，通过修改~/.bashrc、/etc/profile和启用rc.local服务来添加启动脚本的方法。rc.local的设置包括创建文件、赋予执行权限以及启动和检查服务状态。

一、环境：

操作系统：Debian GNU/Linux 10

二、方法1：~/.bashrc

可以添加脚本在 ~/.bashrc末尾执行。

三、方法2：/etc/profile

可以添加脚本在 /etc/profile末尾执行。

四、方法3：rc.local

1、查看一下rc-local.service文件是不是存在
路径：/lib/systemd/system/rc-local.service
内容：

#  (at your option) any later version.

# This unit gets pulled automatically into multi-user.target by
# systemd-rc-local-generator if /etc/rc.local is executable.
[Unit]
Description=/etc/rc.local Compatibility
Documentation=man:systemd-rc-local-generator(8)
ConditionFileIsExecutable=/etc/rc.local
After=network.target

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
RemainAfterExit=yes
GuessMainPID=no

注：这里面就指出了可执行文件是 /etc/rc.local 。

2、默认的状态

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

注：因为没有 /etc/rc.local 这个文件，或者这个文件没有权限。

3、创建 /etc/rc.local
（1）写入内容

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
  
exit 0

注：如果有什么要开启启动的脚本可以插入在 exit 0 之前。

（2）赋予可执行权限

chmod +x /etc/rc.local

3、启动rc.local服务

systemctl start rc.local

注：重启后服务会自动启动

4、重启后查询状态

root@npi:~# systemctl status rc.local
● rc-local.service - /etc/rc.local Compatibility
   Loaded: loaded (/lib/systemd/system/rc-local.service; enabled-runtime; vendor
  Drop-In: /lib/systemd/system/rc-local.service.d
           └─debian.conf
   Active: active (exited) since Tue 2022-01-04 16:06:09 CST; 3min 51s ago
     Docs: man:systemd-rc-local-generator(8)
  Process: 367 ExecStart=/etc/rc.local start (code=exited, status=0/SUCCESS)

Jan 04 16:06:09 npi systemd[1]: Starting /etc/rc.local Compatibility...
Jan 04 16:06:09 npi systemd[1]: Started /etc/rc.local Compatibility.

注：验证确实有执行rc.local内的内容
