node.js - "systemctl start pm2-user-name"给出错误

Question

我正在设置一个新服务器，现在尝试安装 pm2 并按照此说明工作 https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-18-04

尝试 sudo systemctl start pm2-userName 时我收到此错误消息:“pm2-userName.service 的作业失败，因为该服务未采取其单元配置所需的步骤。”

任何帮助将不胜感激，因为我坚持这一点。谢谢!”

到目前为止，我一直按照以下步骤操作:
- sudo npm install pm2@latest -g//(安装好!)
- pm2 start hello.js//(工作正常!)
- pm2 startup systemd//(我得到一个 sudo env PATH... 来复制粘贴)
- 复制粘贴 sudo env PATH=$PATH:/usr/bin /usr/lib/node_modules/pm2/bin/pm2 startup systemd -u carles --hp /home/carles//(并且一切看起来都还不错并且可以正常工作(请参阅下面的启动脚本)
- sudo pm2 save (工作)
-s udo systemctl start pm2-carles (失败!因为 pm2-carles.service 的作业失败，因为该服务未采取其单元配置所需的步骤。)
- systemctl status pm2-carles.service//(已加载但事件:失败(结果:协议(protocol))

I expect sudo systemctl start pm2-carles to run and work, instead I am getting "pm2-carles.service - PM2 process manager

重新启动虚拟服务器对我有用:

sudo reboot

如果这不起作用，请尝试:

ps aux | grep pm2 | grep -v grep | awk '{print $2}' | xargs kill -9

以上杀死了 pm2 服务守护进程，之后您可以使用 root 权限重新启动它。 (这是如果您从目录/usr/bin/pm2 运行)。

从 github pm2 线程获得以上内容
