我嘗試製作一個腳本來自動執行我的實驗。
我的目的是從一個shell腳本,在服務器上運行另一個腳本運行如下命令:
在腳本中執行ssh命令
ssh [email protected] 'sh ControlIperfServer.sh start'
即使文件ControlIperfServer.sh已經放置在服務器的/ root目錄。 COM但是從端子的輸出是:
bash: sh ControlIperfServer.sh start: command not found
雖然我能夠當我在終端鍵入以運行該命令。從腳本執行它時,它只能執行。我的意思是:
當我在終端鍵入命令。有用。
[[email protected] ~]# ssh [email protected] 'sh ControlIperfServer.sh start'
Running IPERF SERVER
[[email protected] ~]#
當我將該命令放入腳本並執行腳本時。這是行不通的。
[[email protected] ~]# ./Runtest.sh
bash: sh ControlIperfServer.sh start: command not found
[[email protected] ~]#
我使用的詳細-v選項以跟蹤
debug1: Next authentication method: publickey
debug1: Trying private key: /root/.ssh/identity
debug1: Offering public key: /root/.ssh/id_rsa
debug1: Server accepts key: pkalg ssh-rsa blen 277

debug1: Authentication succeeded (publickey).

非常感謝你非常非常多的幫助。
添加我Runtest.sh的代碼:
#!/bin/sh
# A script to run test automatically, need modify when using
# Usage:
# ./RunTest.sh <number of test> [threads]
# [threads]: when there is threads, use -P option of Iperf
# Otherwise, run multiple instances of Iperf
# <number of test>: Defaut is 1
# Number of Threads/Processes
# Number of time capture traffic
RUN_IPERF_SERVER="sh ControlIperfServer.sh start"
STOP_IPERF_SERVER="sh ControlIperfServer.sh stop"
RUN_TCPDUMP="sh ControlTCPdump.sh start"
STOP_TCPDUMP="sh ControlTCPdump.sh stop"
RUN_CLIENT="iperf -c"
TARGET_SERVER="10.10.10.253"
REMOTE_SERVER="server.com"
DIRECTORY="CaptureTraffic"
TCP_DURATION="60"
if [ "$1" = "" ]; then
MAX_TEST=1;
else
MAX_TEST=$1;
fi
# Run server daemon on remote server
CMD="ssh -v [email protected]$REMOTE_SERVER \"$RUN_IPERF_SERVER\""
echo Running $CMD
$CMD # Run iperf server remotely
sleep 5 # Waiting for server to run
CMD="ssh -v $REMOTE_SERVER 'mkdir $DIRECTORY && echo ok'"
DIROK="$($CMD)"
if [ "$DIROK" = ok ]; then
mkdir $DIRECTORY
else
echo Cannot create directory\! Please be careful\!
fi
for INCR in $(seq 1 $MAX_TEST)
do
echo Running Test $INCR
#Prepare TCP to capture traffic (run on host)
echo Setting-up TCPdump for capture traffic
FILENAME="$DIRECTORY/CapturedTraffic$INCR.dmp"
ssh $REMOTE_SERVER \'$RUN_TCPDUMP $FILENAME\'
sleep 5
# Running the client (running locally)
if [ "$2" = threads ]; then
echo "Running Iperf Client as threads model"
$RUN_CLIENT $TARGET_SERVER -t $TCP_DURATION -P $INCR
else
echo "Running Iperf Client as processes model"
sh parallel.sh -j $INCR \"$RUN_CLIENT $TARGET_SERVER -t $TCP_DURATION\"
fi
#Stop TCPdump (run on host)
ssh $REMOTE_SERVER '$STOP_TCPDUMP'
sleep 5 #Wait for TCPdump write file to harddrive
done
#Stop Iperf Deamon
ssh $REMOTE_SERVER '$STOP_IPERF_SERVER'
sleep 3
我已經放在一個名爲「server.com」主機上的所有腳本文件。
Runtest.sh是什麼樣的?這聽起來像你可能在某處過分引用了命令名。當我做一個測試命令時,我看到'debug1:發送命令:echo foo'(注意缺少引號)。 – chepner 2013-03-20 16:52:02
@chepner:你應該提供這個答案。這很可能是這種情況。 – Dolda2000 2013-03-20 17:06:56
這是原因,但我不知道足夠的細節來指定真正的解決方案。 – chepner 2013-03-20 17:08:28
