php通过shell调用Hadoop的方法

1.php代码(index.php)

<!DOCTYPE html>
<html>
 
<!-- <style> body{background-color:red} </style> -->
<!-- <style type="text/css"> -->
<!--  body { background:url(渐变绿.jpeg); -->
<!--       width:100%; -->
<!--       height:100%; } </style> -->
<body>
<?php
header('Content-type: text/html; charset=UTF8');
#phpinfo();
$jiaoben = $_GET['jiaoben'];
echo "运行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>";
}

?>
</body>
</html>


2.shell代码（hadoop.sh） 

#!/bin/bash
echo "wordCount test start"
rm -rf ~/file_20141024
mkdir ~/file_20141024
cd ~/file_20141024
echo "Hello World" > file1.txt
echo "Hello China Beijing" > file2.txt
cd /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-00000
echo "wordCount test end"

3. 訪问http://ip:8888/index.php?

jiaoben=hadoop.sh

查询结果：

/user/work/output_20141024/part-r-00000 Beijing 1 China 1 Hello 2 World 1
