[英]I want to use parallel-ssh to run a bash script on multiple servers, but it simple prints the echo statements
我有一個名為sr_run_batch.sh
的bash腳本,它可以實現圖像的超分辨率。 現在我想同時在不同的服務器上進行並行測試。 即。 1在一個給定時間點的虛擬機。 然后在一個時間點,3個然后4個虛擬機。我嘗試寫入命令
for host in $(cat hosts.txt); do ssh "$host" "$command" >"output.$host"; done
ssh-keygen && for host in $(cat hosts.txt); do ssh-copy-id $host; done
文件hosts.txt
包含服務器列表: username@ip
(format)但是當我運行它時,它給了我替換錯誤
因此,我嘗試了pssh(parallel-ssh)
pssh -h hosts-file -l username -P $command
命令是./sr_run_batch.sh
但它沒有運行,所以我將其修改為
pssh -h hosts-file -l ben -P -I<./sr_run_batch.sh
但是,由於某些未知原因,它只是在代碼中打印echo語句。 這是代碼:
NList=(5)
VList=(1)
FList=("input/flower1.jpg" "input/flower2.jpg" "input/flower3.jpg" "input/flower4.jpg")
IList=("320X240" "640X480" "1280X960" "1920X1200")
SList=(2 3)
for VM in ${VList[@]}; do
for ((index=0; index < ${#FList};)) do
file=$FList[$index]
image_size=$IList[$index]
width=`echo $image_size|cut -d "X" -f1`
height=`echo $image_size|cut -d "X" -f2`
for scale_factor in ${SList[@]}; do
for users in ${NList[@]}; do
echo "V: $VM, " "F: $file, " "S: $scale_factor, " "I: $width $height , " "N: $users"
for i in `seq 1 $users` ; do
./sr_run_once.sh $file $width $height $scale_factor &
done
wait
done # for users
done # for scale_factor
done # for index
done # for VM
exit 0
您是否也嘗試使用簡單的bash腳本pssh,那么看看通信設置是否正常?
$ pssh -h hosts.txt -A -l ben -P -I<./uptime.sh
