linux - update-rc.d : error: firewall Default-Start contains no runlevels, 正在中止

Question

我正在尝试添加一项服务，以便它在启动时启动，但不可能，我收到以下错误

$ sudo systemctl enable firewall.service

Synchronizing state of firewall.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable firewall
update-rc.d: error: firewall Default-Start contains no runlevels, aborting

# /etc/systemd/system/firewall.service
[Unit]
ConditionPathExists=/etc/init.d/firewall
after=network.target

[Service]
ExecStart=/etc/init.d/firewall

[Install]
WantedBy=multi-user.target

Answer 1

编辑您的防火墙文件并将其添加到开头

### BEGIN INIT INFO
# Provides:          firewall
# Required-Start:    $all
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:
# Short-Description: your description here
### END INIT INFO

将文件移动到正确的目录

mv /etc/init.d/firewall  /etc/systemd/system/firewall

创建firewall.service文件/lib/systemd/系统/

> /lib/systemd/system/firewall.service

您的firewall.service 文件应包含此内容

 [Unit]
 Description=Firewall

 [Service]
 Type=simple
 RemainAfterExit=yes
 ExecStart=/etc/systemd/system/firewall start
 ExecStop=/etc/systemd/system/firewall stop
 ExecReload=/etc/systemd/system/firewall restart

 [Install]
 WantedBy=multi-user.target

重新加载 systemd 管理器配置并启用防火墙

systemctl daemon-reload
systemctl enable firewall
