在Linux的启动时间中启动脚本的最佳方法是什么 [英] what is the best way to start a script in boot time on linux

问题描述

我想启动系统启动并寻找最佳方法时使用的脚本，我的方法是:

I want to start a script I have on when the system start and looking for the best way, my way is:

• vi/etc/systemd/system/myscript.service

• vi /etc/systemd/system/myscript.service

[Service]
Type=simple
ExecStart=/usr/bin/myscript
CPUSchedulingPolicy=rr
CPUSchedulingPrioty=27
[Install]
WantedBy=multi-user.target graphical.target

systemctl daemon-reload; systemctl enable myscript; systemctl start rmyscript

它工作正常，但只是想知道是否还有另一种更好的方法.

it's working good but just wondered if there another and better way.

推荐答案

有两种方法可以实现此目的，但是以下任何情况都需要root特权.要获得root用户权限，请打开一个终端并运行以下命令:

There are a couple of ways to achieve this, but you will need root privileges for any the following. To get root, open a terminal and run the command:

sudo su

，命令提示符将变为'#'，表示终端会话具有root特权.

and the command prompt will change to '#' indicating that the terminal session has root privileges.

替代#1.添加初始化脚本

在/etc/init.d/myscript中创建一个新脚本:

vi /etc/init.d/myscript

(显然不必将其称为"myscript".)在此脚本中，执行您想做的所有事情.也许只需运行您提到的脚本即可:

(Obviously it doesn't have to be called "myscript".) In this script, do whatever you want to do. Perhaps just run the script you mentioned:

#!/bin/sh
/path/to/my/script.sh

使其可执行:

chmod ugo+x /etc/init.d/myscript

配置初始化系统以在启动时运行此脚本:

Configure the init system to run this script at startup:

update-rc.d myscript defaults

替代#2.将命令添加到/etc/rc.local

vi /etc/rc.local

内容如下:

# This script is executed at the end of each multiuser runlevel
/path/to/my/script.sh || exit 1   # Added by me
exit 0

替代#3.添加新贵职位

创建/etc/init/myjob.conf:

vi /etc/init/myjob.conf

具有以下内容:

description "my job"
start on startup
task
exec /path/to/my/script.sh

顺便说一句:

如果您可以编辑crontab (crontab -e)并创建如下条目，则无需成为root用户:

You don't need to be root if you can edit your crontab (crontab -e) and create an entry like this:

@reboot /path/to/script.sh

这样，您可以以普通用户身份运行它. @reboot只是表示它在计算机启动时运行(不一定只是在重新启动时运行).

This way, you can run it as a regular user. @reboot just means it's run when the computer starts up (not necessarily just when it's rebooted).
