openwrt的启动脚本和定时脚本集锦, 自用

1. 启动脚本, /etc/rc.loca

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.

#2014-11, 上级WiFi不存在则OP中继异常, 切换到AP模式
if ping -w 1 -c 1 www.baidu.com          #ping测试
then    #如果条件ping -c 1 $address为真，即通，则执行该命令；
    echo "$address is online" #如果网络在线则放弃脚本
else #如果网络不在线则开始切换网络
    /xutest/network_ap.sh
fi

#向上级路由映射UPNP端口
/xutest/upnp.sh

#将公网IP发到指定Email
/xutest/getip.sh

#解决3322.org的DDNS的不稳定
sleep 128 /bin/sh /usr/lib/ddns/dynamic_dns_updater.sh myddns 0 &
a=1
while [ $a -le 500 ]
do
    /bin/sh /usr/lib/ddns/dynamic_dns_updater.sh myddns 0 &
    sleep 1h
Done


exit 0

2. 定时脚本, /etc/contrabs/root

*/1 * * * * /xutest/703n_led_blink.sh
*/1 * * * * /xutest/lewei_dongle.sh
*/1 * * * * /xutest/yeelink_photo.sh

0 */1 * * * /xutest/upnp.sh

3.  按键处理, 相关2个文件, 无需重启即可有效
/etc/config/system

config system
    option hostname 'OpenWrt'
    option zonename 'Asia/Shanghai'
    option timezone 'CST-8'
    option conloglevel '8'
    option cronloglevel '8'

config timeserver 'ntp'
    list server '0.openwrt.pool.ntp.org'
    list server '1.openwrt.pool.ntp.org'
    list server '2.openwrt.pool.ntp.org'
    list server '3.openwrt.pool.ntp.org'
    option enable_server '0'

config restorefactory
    option button 'reset'
    option action 'pressed'
    option timeout '2'

config led
    option name 'flashing'
    option sysfs 'tp-link:blue:config'
    option trigger 'timer'
    option delayon '800'
    option delayoff '800'

config led
    option name 'Relay'
    option sysfs 'tp-link:blue:relay'
    option trigger 'none'
    option default '0'

/etc/hotplug.d/button/50-restorefactory, 必须具有X属性

#!/bin/sh

system_config() {
    config_get button "$1" button "reset"
    config_get action "$1" action "pressed"
    config_get timeout "$1" timeout "2"
}

config_load system
config_foreach system_config restorefactory

[ "$BUTTON" = "$button" ] && {

    [ -f /tmp/run/restorefactory.pid ] && read PID < /tmp/run/restorefactory.pid && kill $PID && rm /tmp/run/restorefactory.pid && logger -p user.info -t "restorefactory" "restore to factory defaults aborted"

    [ "$ACTION" = "$action" ] && {

        if [ "$timeout" -gt 0 ]
        then
            sleep "$timeout" && firstboot && reboot &
            echo $! > /tmp/run/restorefactory.pid
            logger -p user.info -t "restorefactory" "restoring to factory defaults in $timeout seconds"
        elif [ "$timeout" -eq 0 ]
        then
            firstboot && reboot &
        else
            logger -p user.info -t "restorefactory" "invalid timeout value ($timeout)"
        fi
    }
}

[ "$BUTTON" = "$button" ] && [ "$ACTION" = "$action" ] && {
    SW=$(uci get system.@led[-1].default)
    [ $SW == '0' ] && (uci set system.@led[-1].default=1; echo 1 > /sys/devices/platform/leds-gpio/leds/tp-link:blue:system/brightness)
    [ $SW == '0' ] || (uci set system.@led[-1].default=0; echo 0 > /sys/devices/platform/leds-gpio/leds/tp-link:blue:system/brightness)
    uci commit

    #/etc/init.d/led restart
}
