重新啟動后systemctl disable name.service不會持久存在

Question

我正在嘗試找到一種在啟動時在Ubuntu 16.04上禁用藍牙的方法，我一直在網上絆腳石的一種方法是使用systemd

基本上

首先，停止服務：

sudo systemctl停止bluetooth.service

然后禁用它：

sudo systemctl禁用bluetooth.service

校驗：

sudo systemctl狀態為bluetooth.service

https://askubuntu.com/questions/744640/best-way-to-deactivate-bluetooth-on-system-startup-with-systemd-and-not-upstar

但是每次我重新啟動后，它都重新啟動，並且我找不到網上有人抱怨systemd disable命令不能像我這樣工作

即使在ubuntu Wiki上，它也應該起作用，這是我做錯了什么嗎？

這是我運行這些命令時的輸出

Answer 1

也許服務是由依賴項啟動的。 您可以嘗試使用systemd的第三級“關閉” ，稱為“屏蔽”：

systemctl mask bluetooth.service

一旦被屏蔽，就根本無法啟動服務，即使是手動也無法啟動。 您可以稍后對其進行“取消屏蔽”。

Answer 2

這是創建腳本的方法，該腳本將在啟動時運行，並執行一項操作以終止Bluetooth服務，並且將執行以下操作（我使用nano，請隨時使用任何其他文本編輯器）：

步驟1：瀏覽至資料夾

cd /etc/systemd/system/

步驟2：首先創建一個腳本，該腳本一旦運行將終止藍牙服務：

nano bluetoothkill.sh

步驟3：輸入以下代碼，保存並退出：

#!/bin/bash
rfkill block bluetooth
exit 0

步驟4：在同一文件夾/ etc / systemd / system /中創建foo.service文件：

nano foo.service

步驟5：輸入以下代碼，保存並退出：

[Unit]
Details=Additional startup scripts
After=network.target

[Service]
ExecStart=/etc/systemd/system/bluetoothkill.sh

[Install]
WantedBy=default.target

步驟6：在終端中運行以下命令：

sudo chmod 744 bluetoothkill.sh

步驟7：在終端中運行以下命令：

sudo systemctl start foo.service

步驟8：重新啟動機器，在下次啟動時，您會注意到默認情況下在啟動時不再啟用藍牙服務。 您仍然可以隨時在設置中或終端運行時啟用它，而不會出現任何錯誤。

如果要在啟動時添加更多腳本，則始終可以編輯foo.service文件，並在[Service]括號下添加其他行以在啟動時運行其他腳本，例如：

ExecStart=/full-script-filepath/newscript.sh
