systemctl状态显示无效死机 [英] systemctl status shows inactive dead

问题描述

我正在尝试编写自己的(简单)systemd服务，该服务可以完成一些简单操作(例如，使用shell脚本将数字1到10写入文件).我的服务文件如下所示.

I am trying to write my own (simple) systemd service which does something simple.( Like writing numbers 1 to 10 to a file, using the shell script). My service file looks like below.

[Unit]
Description=NandaGopal
Documentation=https://google.com
After=multi-user.target

[Service]
Type=forking  
RemainAfterExit=yes
ExecStart=/usr/bin/hello.sh &

[Install]
RequiredBy = multi-user.target

这是我的shell脚本.

This is my shell script.

#!/usr/bin/env bash

source /etc/profile
a=0
while [ $a -lt 10 ]
do
   echo $a >> /var/log//t.txt
        a=`expr $a + 1`
done

由于某种原因，该服务无法启动，并且systemctl显示以下输出.

For some reason, the service doesn't come up and systemctl is showing the below output.

root@TARGET:~ >systemctl status -l hello
* hello.service - NandaGopal
   Loaded: loaded (/usr/lib/systemd/system/hello.service; disabled; vendor     preset: enabled)
   Active: inactive (dead)

曾经试图找出过去两天出了什么问题.

Been trying to figure out what went wrong for the last 2 days.

推荐答案

• 您已经设置了 Type = Forking ，但是您的服务无法正常工作.尝试Type = oneshot
• 您有一个&"您的 ExecStart 行，这不是必需的.
• 该服务已被 disabled 禁用，这意味着它没有启用在启动时启动.您应该运行 systemctl enable hello 将其设置为在启动时启动.
• You have set Type=Forking, but your service doesn't work. Try Type=oneshot
• You have a "&" your ExecStart line, which is not necessary.
• The service is disabled, which means it was not enabled to start at boot. You should run systemctl enable hello to set it to start at boot.

您可以检查 man systemd.directives 来查找可以在 unit 文件中使用的所有指令的索引.

You can check man systemd.directives to find an index of all the directives that you can use in your unit files.
