如果“timidity.service”服务在系统启动时自动运行，则无法启动

  • 772

创建timidity.service文件和相关符号链接以便在系统重启时自动启动服务后，我重新启动系统并输入以下输入：

sudo systemctl status timidity

输出：

我的用户名与该群组相关联audio。

符号链接：

/usr/lib/systemd/system/multi-user.target.wants/timidity.service

服务：

/usr/lib/systemd/system/timidity.service

包含：

[Unit]
Description=TiMidity++ Daemon
After=sound.target
Requires=sound.target

[Service]
ExecStart=/usr/bin/timidity -iA Os
Type=simple

[Install]
WantedBy=multi-user.target

我还尝试将“timidity.service”文件更改为以下内容：

[Unit]
Description=TiMidity++ Daemon
After=pulseaudio.service
Requires=pulseaudio.service

[Service]
ExecStart=/usr/bin/timidity -iA Os
Type=simple

[Install]
WantedBy=multi-user.target

但再次重启系统后，错误仍然相同。

尝试在系统已启动的情况下从终端手动启动服务，服务正确启动。

我做错什么了？

    解决方案如下：

    服务：

    /usr/lib/systemd/system/timidity.service

    包含：

    [Unit]
Description=TiMidity++ Daemon

[Service]
ExecStart=/usr/bin/timidity -iA Os

[Install]
WantedBy=sound.target

    系统重启时自动启动服务：

    sudo systemctl enable timidity

    创建符号链接：

    /etc/systemd/system/sound.target.wants/timidity.service

    为了使自动服务启动不能通过命令禁用sudo systemctl disable timidity，请运行此命令而不是上面的命令：

    ln -sf ../timidity.service /usr/lib/systemd/system/sound.target.wants/timidity.service

    创建符号链接：

    /usr/lib/systemd/system/sound.target.wants/timidity.service

    该文件夹sound.target.wants已存在于刚才提到的路径内。

    该解决方案适用于多用户，并且用户不需要成为audio组的一部分。

    此解决方案在 100% 的系统重启中有效。
