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"
