我想在重启Ubuntu 16.04时使用Supervisor。
这是/etc/systemd/system/supervisord.service
[Unit]
Description=Supervisor daemon
Documentation=http://supervisord.org
After=network.target
[Service]
ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf
ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown
ExecReload=/usr/bin/supervisorctl $OPTIONS reload
KillMode=process
Restart=on-failure
RestartSec=42s
[Install]
WantedBy=multi-user.target
但是当我重启ubuntu系统时，它不起作用。
我尝试命令：
sudo journalctl -u supervisord.service
据此：
-- Reboot --

尝试命令：
