Java进程脚本

[server@hadoop102 bin]$ pwd
/home/server/bin
[server@hadoop102 bin]$ vim jpsall

#!/bin/bash

for host in hadoop102 hadoop103 hadoop104
do
        echo =================$host===================
                ssh $host jps
done

[server@hadoop102 bin]$ chmod 777 jpsall

使用分发脚本分发

[server@hadoop102 bin]$ xsync /home/server/bin
======= hadoop102 ======
sending incremental file list

sent 186 bytes  received 17 bytes  135.33 bytes/sec
total size is 3,396  speedup is 16.73
======= hadoop103 ======
sending incremental file list
bin/

sent 189 bytes  received 20 bytes  139.33 bytes/sec
total size is 3,396  speedup is 16.25
======= hadoop104 ======
sending incremental file list
bin/

sent 189 bytes  received 20 bytes  139.33 bytes/sec
total size is 3,396  speedup is 16.25

使用,比如说hadoop启动后

[server@hadoop102 bin]$ jpsall
=================hadoop102===================
8256 Jps
7475 NameNode
7589 DataNode
7958 NodeManager
8138 JobHistoryServer
=================hadoop103===================
7988 Jps
7230 DataNode
7422 ResourceManager
7566 NodeManager
=================hadoop104===================
7506 NodeManager
7285 DataNode
7719 Jps
7400 SecondaryNameNode

附xsync脚本(分发脚本)

[server@hadoop104 bin]$ cat xsync
#!/bin/bash

#1. 判断参数个数
if [ $# -lt 1 ]
then
        echo Not Enough Argument!
        exit;
fi

#2. 遍历集群所有机器
for host in hadoop102 hadoop103 hadoop104
do
        echo =======  $host  ======
        #3. 遍历所有目录，挨个发送
 
        for file in $@
        do
                #4. 判断文件是否存在
                if [ -e $file ]
                        then
                                #5. 获取父目录
                                pdir=$(cd -P $(dirname $file);pwd)

                                #6. 获取当前文件的名称
                                fname=$(basename $file)
                                ssh $host "mkdir -p $pdir"
                                rsync -av $pdir/$fname $host:$pdir
                        else
                                echo $file does not exits!
                fi
        done
done
