Question

我正在DigitalUcean服务器上创建systemd service file，该服务器具有ubuntu 18和NGINX作为Web服务器。

systemd service file处的脚本为：

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
Type=oneshot
User=root
Group=www-data
WorkingDirectory=/var/www/computationalMarketing
ExecStart=/var/www/computationalMarketing/bin/activate
ExecStart=/var/www/computationalMarketing/computationalMarketing/code/computationalMarketing/gunicorn --access-logfile --bind unix:/tmp/gunicorn.sock computationalMarketing.wsgi:application

[Install]
WantedBy=multi-user.target

错误日志为：

Warning: The unit file, source configuration file or drop-ins of gunicorn.service changed on disk. Run 'systemctl daemon-reload' to reload units.
● gunicorn.service - gunicorn daemon

Jul 03 11:57:19 tfm-rius systemd[1]: Failed to start gunicorn daemon.
root@tfm-rius:/var/www/computationalMarketing/computationalMarketing/code/computationalMarketing#

此错误与服务正文中使用的用户有关，还是与execStart命令之一有关？

编辑：

我将服务正文中的用户更改为：www-data

现在，日志错误为：gunicorn.service: Failed to execute command: Permission denied

应该使用哪个用户？我该如何纠正此错误？

Edit2

正如奥利弗（Oliver）在评论中所说，我执行：

ls -la /var/www/computationalMarketing/bin/activate

输出为：

-rw-r--r-- 1 root root 2243 Jun 28 10:11 /var/www/computationalMarketing/bin/activate

我有两个ExecStart，因为我必须先激活virtualenv，然后再激活gunicorn才能使应用正常工作。

执行后登录：chmod 755 /var/www/computationalMarketing/bin/activate

systemd服务文件执行命令失败：权限被拒绝
