Openwrt 启动dae的init.d脚本

Openwrt 启动dae的init.d脚本

一、使用说明: 请把以下内容替换到 /etc/init.d/dae 感谢@[tty228](https://github.com/tty228)给的改进版本，修复了dnsmasq问题
```Bash
#!/bin/sh /etc/rc.common

START=99
STOP=99

LOG_FILE="/var/log/dae.log"
# 如果不需要生成日志，取消下一行的注释
#LOG_FILE="/dev/null"

start_pre() {
if ! /usr/bin/dae validate -c /etc/dae/config.dae; then
echo "dae config file /etc/dae/config.dae is invalid or too open, exiting."
exit 1
fi
}

start() {
# 检查 dae 进程是否已经在运行
if [ $(pidof /usr/bin/dae) ]; then
echo "dae process is already running!"
return 1
fi
# 清空并添加 DNS 转发，否则关闭劫持后，会因无网络无法启动 dae
uci -q del dhcp.@dnsmasq[0].server
uci add_list dhcp.@dnsmasq[0].server='223.5.5.5'
# 关闭 OpenWrt dnsmasq 53 劫持
uci set dhcp.@dnsmasq[0].noresolv='1'
uci commit dhcp
/etc/init.d/dnsmasq reload
echo "Disable the 'noresolv' feature in Dnsmasq"
# 清空日志，自选
echo "" > $LOG_FILE
# 启动 dae 进程，并将日志输出到 LOG_FILE 文件中
start_pre
/usr/bin/dae run --disable-timestamp -c /etc/dae/config.dae >> $LOG_FILE 2>&1 &
echo "Started dae process."

# 记录进程 PID
echo $! > /var/run/dae.pid

}

stop() {
# 停止 dae 进程
if [ -f /var/run/dae.pid ]; then
pid=$(cat /var/run/dae.pid)

kill -15 $pid
echo "dae stopped"
# 清空添加的 DNS 转发，并恢复 noresolv 功能
uci -q del dhcp.@dnsmasq[0].server
uci set dhcp.@dnsmasq[0].noresolv='0'
uci commit dhcp
/etc/init.d/dnsmasq reload
echo "Enable the 'noresolv' feature in Dnsmasq"
else
echo "dae is not running"
fi

# 删除进程 PID 文件
rm -f /var/run/dae.pid
}

restart() {
stop
sleep 1
start
}

reload() {
# 从 PID 文件中读取进程 ID
if [ -f /var/run/dae.pid ]; then
pid=$(cat /var/run/dae.pid)

# 重新加载 dae 进程
/usr/bin/dae reload $pid
echo "Reloaded dae process."
else
echo "dae process is not running!"
fi
}
```
二、扩展功能:
1.暂停dae: ``` /usr/bin/dae suspend $(cat /var/run/dae.pid)```
2.查看日志: ``` tail -f /var/log/dae.log ```
（ps:自己注意dae日志文件大小 ，已知问题OPENWRT下日志文件大于512M dae会崩，建议安装第三方日志管理软件）

以下废弃。。
三、目前已知dae会和Dnsmasq发生冲突
1.
```
echo "nameserver 223.5.5.5" > /etc/resolv.conf
```
2.建议把 Dnsmasq DNS监听端口设置为 0 或者 /etc/init.d/dnsmasq stop (ps：慎用！！！可能会失去dhcp功能)（补充：不需要关，见评论区）

Start with the proposed /etc/init.d/dae OpenWrt rc.common script and review how this repository packages or documents service startup. Check the dae validate, run, reload, suspend, and PID-file commands together with the dnsmasq changes on OpenWrt. Done means an agreed integration location and verified start, stop, restart, and reload behavior.
