下午好
我在 Debian 上(在 Raspberry Pi 上)使用 update-rc.d 插入启动服务时遇到问题
我运行的插入服务的命令是:
sudo update-rc.d setdatetime defaults
chmod 权限设置为 755 的服务本身(文件/etc/init.d/setdatetime)如下所示:
#!/bin/bash
### BEGIN INIT INFO
# Provides: update
# Required-Start: $syslog
# Required-Stop: $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Description: This service is used to set date and time
### END INIT INFO
case "$1" in
start)
echo "Setting date and time"
sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z"
;;
stop)
;;
*)
echo "Usage: /etc/init.d/setdatetime start|stop"
exit 1
;;
esac
exit 0
我可以使用
毫无问题地运行该服务sudo /etc/init.d/setdatetime start
ls/etc/rc*.d 列出已安装的服务:
但是服务不开机运行!我错过了什么？？？

最佳答案
看起来你的依赖有问题。 您必须确保系统日志服务已在您的 setdatetime 服务之前启动。
显然，如果您手动启动服务，则计算机已经完成启动，因此系统日志正在运行，因此您的服务可以正常工作。
你也可以尝试去掉对syslog的依赖。
更好的是: 由于您的服务只运行一次，您还可以将适当的命令放在/etc/rc.local 文件最后一行之前。
关于linux - 服务不会在 Linux Boot 上启动，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27157485/
