php通过shell调用Hadoop的方法

1.php代码(index.php)

 <!-- <style> body{background-color:red} </style> --><!-- <style type="text/css"> --><!--  body { background:url(渐变绿.jpeg); --><!--       width:100%; --><!--       height:100%; } </style> --><?phpheader ('Content-type: text/html; charset=UTF8');#phpinfo();$jiaoben = $_GET['jiaoben'];echo "执行Hadoop的log信息：";$ret= system("sh /home/work/$jiaoben", $status);if($status != 0) { echo ' failed, status=' . "$status\n"; } else {	echo $ret;        echo "<br><br>";}?>

2.shell代码（hadoop.sh）

#!/bin/bashecho "wordCount test start"rm -rf ~/file_20141024mkdir ~/file_20141024cd ~/file_20141024echo "Hello World" > file1.txtecho "Hello China Beijing" > file2.txtcd /home/work/hadoop/bin ./hadoop dfs -rmr input_20141024./hadoop dfs -rmr output_20141024./hadoop fs -mkdir input_20141024#hadoop fs -chomod -R 777 /input_20141024./hadoop fs -put ~/file_20141024/file*.txt input_20141024./hadoop jar /home/work/hadoop/hadoop-examples-1.1.2.jar wordcount input_20141024 output_20141024./hadoop fs -ls output_20141024./hadoop fs -cat output_20141024/part-r-00000echo "wordCount test end"

3. 访问http://ip:8888/index.php?jiaoben=hadoop.sh

查询结果：
