如何真正、完全禁用 Gnome 跟踪器?

如何真正、完全禁用 Gnome 跟踪器?

禁用占用资源、复制数据的 Gnome 跟踪器守护进程比应有的困难得多。我正在使用 Gnome 运行最近安装的(稳定)Debian 11.2。

我发现的一项建议是编辑所有/etc/xdg/autostart/tracker-*.desktop文件,以便

X-GNOME-Autostart-enabled=false (它是true

尽管据称这对某人有效,但从前,可惜的是,这种改变并没有产生明显的效果。

由于我正在运行跟踪器的版本 2,我也尝试过:

systemctl --user mask tracker-store.service tracker-miner-fs.service tracker-miner-rss.service tracker-extract.service tracker-miner-apps.service tracker-writeback.service

显然,这种方法有效,尽管系统日志仍然不断报告跟踪器服务“成功”。也许这些条目是如何为跟踪器服务配置 systemd 的产物。 “屏蔽”方法的问题在于,重新启用跟踪器守护进程的反向操作(mask-> unmask)对我来说不起作用。 (是的,我按照指示重新启动。然而,跟踪器守护进程没有恢复运行。)

答案1

我有同样的问题;我禁用它:

sudo systemctl --global mask tracker-miner-fs-3.service
sudo systemctl --global mask tracker-xdg-portal-3.service

当然,这应该可以防止服务再次启动全部用户;然而,如果你想阻止当前的,你应该杀死他们。

我正在使用 debian sid。

答案2

事实证明,整个/etc/xdg/autostart/tracker-*.desktop过程在多个方面存在误导:

  1. 跟踪器守护程序和这些文件之间不存在一一对应的关系。有 2 个这样的文件,但有 3 个守护进程。

  2. 我仅通过研究系统日志才发现这三个守护进程的存在/身份。

  3. 跟踪器都在用户空间中。如果用户未运行,则跟踪器守护程序不会运行。当,于建议,我用过:

    systemctl --user mask tracker-store.service tracker-miner-fs.service tracker-miner-rss.service tracker-extract.service tracker-miner-apps.service tracker-writeback.service
    

    ...(正如我之前报道的那样确实有效),我在当前用户的主目录中创建符号链接。~/.config/systemd/user例如,在 Debian 11/Gnome 中,这些位于tracker-extract.service -> /dev/null

  4. 但有一个问题:您必须以您希望禁用其跟踪器守护程序的用户身份登录才能运行systemctl --user ...。这对于打算运行但不登录的用户来说很不方便。其中一个用户是Debian-gdm,显然默认情况下,跟踪器守护程序在 gdm 问候程序运行时运行。更糟糕的是,sudo -u thisuser systemctl --user ...即使我以 root 身份登录也无法工作。因此,为了完全禁止跟踪器守护进程运行,您必须找到一种以 Debian-gdm 身份登录的方法。

因此,我目前解决真正禁用跟踪器守护进程问题的解决方案只是编写脚本,在每个受影响的用户的目录中创建和删除这些链接。重要的是要了解符号链接的名称会有所不同,具体取决于您运行的是跟踪器 v2 还是 v3。同样重要的是要了解,并非systemctl --user ...所有发行版都使用上面提到的所有服务。在 Debian 11/Gnome 上,至少到目前为止,只使用了 6 个中的 3 个。不过,屏蔽(创建对应的符号链接)未使用的链接似乎并没有什么坏处。

如果跟踪器守护进程一直在运行,它们就会创建数据,这些数据的存在可能会也​​可能不会产生安全问题。 (这些数据当然是我所关心的。)要删除这些数据,据称推荐的程序是:

tracker reset --hard(对于 v2)

tracker3 reset -s -r(据说是对于 v3)

但同样,您需要以要销毁跟踪器数据的用户身份登录。我再次发现,对于每个用户来说,简单地删除它更安全、更容易,

~/.cache/tracker

~/.local/share/tracker

或跟踪器数据恰好存储的任何地方。

您可能还希望考虑如何处理先前泄漏到系统日志中的详细跟踪器报告。

最近我的机器也遇到了同样的问题,全新安装后,它占用CPU资源,使电脑变慢。我的解决方案是更改其值以使其运行,但使其无法执行任何工作。下面是需要设置值的脚本:

#!/usr/bin/env bash

# make tracker3 daemon non workable & idompotent
# this script will reset its settings, and configure tracker3 daemon, to not let it do anyting.
# if other code has dependency on this tracker, then it will not break, but we also do achieve our goal.

# looking at source code https://gitlab.gnome.org/GNOME/tracker-miners/-/blob/master/src/miners/fs/tracker-main.c#L406

tracker3 reset -s -r

tracker3 daemon --kill

或者,查看我的要点:使 gnome 跟踪器禁用或完全停止

答案4

我将跟踪器服务重定向到 bin/true。它的侵入性较小。由于它们是用户级服务,因此创建覆盖目录并覆盖您家中的服务,例如:

#! /bin/bash
for t in tracker-extract tracker-miner-fs tracker-store tracker-writeback; do
  SVD=${HOME}/.config/systemd/user/${t}.service.d
  if [ ! -d ${SVD} ]; then
    mkdir -p ${SVD}
  fi
cat > ${SVD}/override.conf << EOF
[Service]
Type=
Type=oneshot
ExecStart=
ExecStart=/bin/true
Restart=
Restart=no
EOF
done

我使用的是 Debian 11
