試圖在腳本有條件

Question

此代碼對樹莓PI3運行

我有一個腳本/etc/rc2.d/S05frameapp有條件地啓動hostapd啓動/ usr/sbin目錄/ hostapd（查看是否無線（此部分被運行，如果沒有wifi已經建立一套該設備）

echo "restarting etho" 
/sbin/ifup wlan0 

echo "Starting hostapd"; 
/usr/bin/nohup /usr/sbin/hostapd -B -P /var/run/hostapd.pid /etc/hostapd/hostapd.conf >> /tmp/hostapd.log 2>&1 & 

echo "Starting dnsmasq "; 
/usr/sbin/service dnsmasq start; 

echo "Starting wifi_config node"; 
cd /home/wifi_listener/ 
/usr/bin/nohup /usr/local/bin/node app.js >> /tmp/nodeapp.log 2>&1 & 

從nohup的已設置或不）

腳本，在/tmp/hostapd.log我見

cat /tmp/hostapd.log 
Configuration file: /etc/hostapd/hostapd.conf 
Failed to create interface mon.wlan0: -95 (Operation not supported) 
Could not set channel for kernel driver 
Interface initialization failed 
wlan0: interface state UNINITIALIZED->DISABLED 
wlan0: AP-DISABLED 
wlan0: Unable to setup interface. 
hostapd_free_hapd_data: Interface wlan0 wasn't started 

，但如果我現在登錄（通過硬連線網絡），並運行以下它的工作原理...

#/usr/sbin/hostapd -B -P /var/run/hostapd.pid /etc/hostapd/hostapd.conf 
Configuration file: /etc/hostapd/hostapd.conf 
Failed to create interface mon.wlan0: -95 (Operation not supported) 
wlan0: Could not connect to kernel driver 
Using interface wlan0 with hwaddr b8:27:eb:40:bd:a4 and ssid 
"WhatUlooknAtWillis" 
wlan0: interface state UNINITIALIZED->ENABLED 
wlan0: AP-ENABLED 

，所以我想kinfod這可能是一個時間問題？這就是爲什麼我現在有腳本運行S05

感謝您的幫助

我發現這個問題。 它開始hostapd和的dnsmasq的順序

是你需要先啓動的dnsmasq修復，然後開始hostapd

echo "Starting dnsmasq "; 
/usr/sbin/service dnsmasq start 

echo "Starting hostapd"; 
/usr/bin/nohup /usr/sbin/hostapd -B -P /var/run/hostapd.pid /etc/hostapd/hostapd.conf >> /tmp/hostapd.log 2>&1 &
