uWSGI 的 Systemd 单元文件失败

使用 Flask、NGINX 和 uWSGI，我已成功设置了一个应用程序，用于通过 Twilio 发送和接收短信。一切都运行正常，只是它在我的个人用户帐户（名为 trinitrogen）下运行。我想将其移动到其他用户帐户（名为 apps）下运行，但遇到了 systemd 单元文件问题。我遇到的最大困难是，我甚至找不到错误的良好日志，所以我不知道从哪里开始

首先，我的作品基于本教程大部分都成功了，正是共享的内容

我创建了新用户并将其添加到 wheel

[apps@argon ~]$ groups
apps wheel

将 repo 克隆到应用程序主目录中，在目录中设置一个名为 venv 的虚拟环境，安装所有 python 包，在命令行中成功测试 uwsgi

[apps@argon PowderMonitor]$ uwsgi --socket 10.0.0.221:8080 --protocol=http -w wsgi:app

效果很好。我继续设置 systemd 文件，但在这里我遇到了障碍。下面是当前文件，以及尝试重新启动服务后的输出。

[apps@argon PowderMonitor]$ cat /etc/systemd/system/TwilioApp.service
[Unit]
Description=uWSGI - TwilioApp - apps acccount
After=network.target

[Service]

[Install]
WantedBy=multi-user.target
[apps@argon PowderMonitor]$ sudo systemctl restart TwilioApp.service
[apps@argon PowderMonitor]$ sudo systemctl status TwilioApp.service -l

下面是 TwilioApp.service 文件的示例，它在我的 trinitrogen 帐户下完美运行。请注意，我唯一更改的是用户和 3 个目录中的内容

[trinitrogen@argon PowderMonitor]$ cat TwilioApp.service.example
[Unit]
Description=uWSGI instance to serve TwilioApp
After=network.target

[Service]
User=trinitrogen

WorkingDirectory=/home/trinitrogen/Python/PowderMonitor

ExecStart=/home/trinitrogen/Python/PowderMonitor/venv/bin/uwsgi --ini TwilioApp.ini

[Install]
WantedBy=multi-user.target

下面是用于 uwsgi 的 TwilioApp.ini，它与我在“trinitrogen”帐户下成功运行的版本以及我的“apps”帐户下的版本完全相同。

[apps@argon PowderMonitor]$ cat TwilioApp.ini
[uwsgi]
module = wsgi:app

master = true
processes = 5

socket = TwilioApp.sock
chmod-socket = 664
vacuum = true
#location of log files
logto = /var/log/uwsgi/TwilioApp.log
die-on-term = true
