Question

您好我的Windows 10 PC上运行了一个apache webserver，其中包含xampp和RaspberryPi，并通过脚本连接到它。该脚本检查Web服务器是否在特定端口上可用，如果可用，则启动浏览器并在服务器不再可用时关闭它。这是我的剧本：

#!/bin/bash

### BEGIN INIT INFO
# Provides:          browerstartup.sh
# Required-Start:    
# Required-Stop:     
# Should-Start:      
# Should-Stop:       
# X-Start-Before:    
# X-Stop-After:      
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# X-Interactive:     
# Short-Description: If connection available, connecT!
# Description:       If connection is available on port 80: Then connect.
### END INIT INFO

server="192.168.16.74"
sleep=10

while [ true ] ; do
echo "Script start" >> /home/pi/browserlog
 midori=$(pgrep "midori")
 nc -w 5 -z $server 80 >/dev/null 2>&1
 if [ $? -ne 0 ] ; then
  echo "Server isnt running!" >> /home/pi/browserlog
  if [ $midori ] ; then
   echo "Midori is still running but server is offline: Killing midori"
   kill $midori
  fi
 else
  echo "Server is running!" >> /home/pi/browserlog
  if ! [ $midori ] ; then
   echo "Starting midori" >> /home/pi/browserlog
   midori -e Fullscreen -a http://$server/Website/t1&
  fi 
 fi
echo "Sleep $sleep" >> /home/pi/browserlog
 sleep $sleep
done

我第一次启动网络服务器时连接并启动midori，如果我停止网络服务器，它会关闭midori。但是，如果我再次启动网络服务器，它就不会再启动midori了，我不知道为什么......

这是我的browserlog文件：

Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start

我在这里手动停止了脚本！

也许你可以帮助我......

我安装了midori并为你兄弟做了一个新剧本：）

#!/bin/bash

ssl_activated=0

if [ "${ssl_activated}" -eq 1 ]; then
    parameters="-a https://${server}/Website/t1&"

    parameters="-a http://${server}/Website/t1&"
fi

browser_pid=""

#Optional, initialize log
rm -rf "${log_path}" >/dev/null 2>&1
echo "Script start" > "${log_path}"

while true; do
    echo "Loop start, checking server..." >> "${log_path}"
    nc -w 5 -z ${server} 80 >/dev/null 2>&1
    if [ $? -ne 0 ] ; then
        echo "Server isnt running!" >> "${log_path}"
        if [ -n "${browser_pid}" ]; then
            echo "There is a browser, let's kill it!" >> "${log_path}"
            kill "${browser_pid}" &> /dev/null
        fi
    else
        echo "Server is running!" >> "${log_path}"
        browser_pid=$(pgrep midori)
        if [ -n "${browser_pid}" ]; then
            echo "Midori is running and server is online" >> "${log_path}"
        else
            echo "Server is online but midori is not running, starting it!" >> "${log_path}"
            eval "${browser} ${parameters} >/dev/null 2>&1 &"
            browser_pid=$!
        fi
    fi
    echo "Sleep ${sleep}" >> "${log_path}"
    sleep ${sleep}
done

Midori浏览器不会在脚本中第二次启动
