我正在尝试将我的一个初始化脚本转换为 systemd，但无济于事。
[Unit]
Description=My Service
After=network.target
Wants=mysql.service
[Service]
Type=oneshot
PIDFile=/var/run/MyService.pid
ExecStart=nohup /usr/local/bin/php -f /home/user/www/myservice.php > /dev/null 2>&1
[Install]
WantedBy=multi-user.target
输出：
root@localserver [/etc/systemd/system]# service myservice restart
Redirecting to /bin/systemctl restart myservice.service
Failed to restart myservice.service: Unit myservice.service failed to load: Invalid argument. See system logs and 'systemctl status myservice.service' for details.
root@localserver [/etc/systemd/system]# service myservice status
Redirecting to /bin/systemctl status myservice.service

Apr 12 12:48:27 localserver systemd[1]: [/etc/systemd/system/myservice.service:9] Executable path is not absolute, ignoring: nohup /usr/local/bin/php -f /home/user/www/myservice.php > /dev/null 2>&1
Apr 12 12:48:27 localserver systemd[1]: myservice.service lacks both ExecStart= and ExecStop= setting. Refusing.
root@localserver [/etc/systemd/system]#
知道为什么它不起作用吗？
答案1
systemd 需要绝对路径：
ExecStart=/usr/bin/nohup /usr/local/bin/php -f /home/user/www/myservice.php > /dev/null 2>&1
