我想从我的机器打开远程机器浏览器。我已经设置了无密码连接(考虑到两个系统都是相同的n/w并且是可信的)。从PHP调用shell脚本没有按预期工作
我能够在下面的脚本运行来启动浏览器,这3个参数
一)。用户名
b)。远程机器的IP地址
c)。 url在Firefox中打开
如果我在我的bash shell中运行这个脚本,我可以打开浏览器而没有任何问题。但是如果我在PHP中调用这个,我无法在远程机器上启动浏览器......它显示所有调试打印,但打开浏览器失败。任何指针都非常有帮助。
下面是我的shell脚本在远程机器上打开浏览器。
#!/bin/bash
if test $# != 3;
then
echo "
$0
This command line script is used to launch, browser remotely. You need to pass 3 arguments to this script.
YOU NEED TO PASS 3 ARGUMEMTS TO THIS SCRIPT,
For example , \$> sh $0 \"<userNameofRemoteSystem>\" \"<remoteSystemIP>\" \"<webPageAddress>\"
\$> sh $0 \"Uname\" \"172.17.64.94\" \"mail.google.com\" \n";
exit 1
fi
echo "<br><br>\nRECEIVED PARAMETERS,\n\tuserName\t-> |$1|\n\tipAddress\t-> |$2|\n\twebURL\t\t-> |$3|\n\n<br>";
echo "<br>Checking if Connection to |$2| WITH USERNAME |$1| is password less???<br><br>";
sleep 2
echo "<br>grep -wc $1 /home/user/.ssh/authorized_keys<br>";
count=`grep -wc $1 /home/user/.ssh/authorized_keys`;
echo "<br>got process count=|$count|<br>"
sleep 2
if [ "$count" != 1 ];
then
echo "
Looks like password less connection to |$2| is not configured with this server for username |$1|..
Please congfigure the same and run this script again...\n";
fi
echo "SUCCESSFULLY CONNECTED, LAUNCHING BROWSER ON |$2| WITH |$3|\n";
ssh [email protected]$2 "nohup sh openBrowser.sh $3" &
PID=$$;
echo "PID IS |$PID|\n";
sleep 2;
echo "<br>PROCESS OUTPUT LOOKS LIKE THIS";
ps aux | grep $PID | grep -v grep
echo "<br>";
echo "after sleep";
kill -9 $PID && echo "after kill pid=$PID, passed ssh [email protected]$2 \"nohup sh openBrowser.sh $3\" &";
下面是我用来调用shell脚本的php脚本。
<?php
$c_url=$_POST['url'];
$c_name=$_POST['uname'];
$c_ip=$_POST['ipaddress'];
$output = system("/bin/sh /home/user/launchBrowser_remote.sh $uName $ipADDR $c_url");
echo "$output";
?>
貌似我得到错误的PID内部shell脚本和其杀死来电脚本,而不是启动SSH远程..... BTW我曾经尝试都exec
和shell_exec
,但没有运气。
任何指针是很大的帮助
感谢
感谢您的回复。是的,Web服务器没有密码连接,这解决了这个问题。再次感谢。 – cb24 2013-05-10 04:48:08
