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

[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)

注:验证确实有执行rc.local内的内容
