特定服务后启动systemd服务? [英] Start systemd service after specific service?

问题描述

我有一个一般性的问题.在特定的 *.service 成功启动后，如何启动 systemd 单元 *.service?

更具体的问题是，如何在 mongodb.service 启动后才启动 website.service ?换句话说，website.service 应该依赖于 mongodb.service.

解决方案

在 .service 文件中的 [Unit] 部分:

[单位]说明=我的网站After=syslog.target network.target mongodb.service

重要的部分是mongodb.service

手册页对其进行了描述，但是由于格式的原因，乍一看并不那么清楚

systemd.unit - 格式良好

systemd.unit - 格式不太好

I have a general question. How does one start a systemd unit *.service after a particular *.service has started successfully?

More specific question is, how do I start website.service only after mongodb.service has started? In other words website.service should depend on mongodb.service.

解决方案

In the .service file under the [Unit] section:

[Unit]
Description=My Website
After=syslog.target network.target mongodb.service

The important part is the mongodb.service

The manpage describes it however due to formatting it's not as clear on first sight

systemd.unit - well formatted

systemd.unit - not so well formatted
