以 root 以外的系统用户身份在 CentOS 上运行服务

我创建了一个系统用户jackett( useradd -r jackett)，并尝试在 CentOS 7 上在该用户下运行 systemd 服务。

服务文件：

[Unit]
Description=Jackett Daemon
After=network-online.target

[Service]
Type=simple
user=jackett
group=jackett
ExecStart=/usr/bin/mono --debug /opt/Jackett/JackettConsole.exe --NoRestart

[Install]
WantedBy=multi-user.target

服务状态：

[root@server Jackett]# systemctl status jackett

问题显然是 systemd 特别注重 case:User而不是user:

[Unit]
Description=Jackett Daemon
After=network-online.target

[Service]
Type=simple
User=jackett
Group=jackett
ExecStart=/usr/bin/mono --debug /opt/Jackett/JackettConsole.exe --NoRestart

[Install]
WantedBy=multi-user.target
