systemctl daemon-reload是一个命令,用于重新加载systemd的系统服务配置文件。当你修改了一个systemd服务的配置文件,比如 /etc/systemd/system/xxx.service,需要重新加载这个配置文件以使修改生效,就需要运行systemctl daemon-reload命令,它会通知systemd重新读取配置文件。修改了systemd配置文件后,如果不运行systemctl daemon-reload,那么systemd将无法识别你的修改,服务也不会正常启动。

systemctl daemon-reload
As an AI language model, I do not have access to the system's environment, so I cannot execute commands. However, I can explain what the command "systemctl daemon-reload" does.
The "systemctl daemon-reload" command is used to reload the systemd manager configuration files. When there is a change in a systemd unit file (for example, a new service is added or an existing service is modified), the daemon-reload command can be used to reload the configuration files and update the systemd manager with the new configuration. This ensures that the changes are applied and the system is aware of the new or modified services.
命令sudo systemctl daemon-reload和systemctl --user daemon-reload
"sudo systemctl daemon-reload" 和 "systemctl --user daemon-reload" 都是用来刷新系统服务管理器(Systemd)的配置文件缓存的命令。它们通常用于更新或修改了systemd相关的配置文件后,需要让系统重新读取并应用这些更改。
1. `sudo systemctl daemon-reload`:这个命令是以超级用户(root或通过sudo)权限运行的,它会影响整个系统的系统服务配置。当你改动了系统范围的systemd配置文件(如 /etc/systemd/system/ 或 /lib/systemd/system/),使用此命令可以使得systemd重新加载配置,以便立即生效新的设置。
2. `systemctl --user daemon-reload`:这个版本的命令则是针对用户的,只影响用户的systemd环境。如果你在~/.config/systemd/user/目录下的用户特定的服务或定时任务有改变,你可以使用此命令来更新该用户环境下的配置缓存。
