SSH exited without connecting to server in shell script
I am trying to connect to the servers and cd into each directory. But when I tried to SSH into the first server which is server1 , the error it gave me was
Pseudo-terminal will not be allocated because stdin is not a terminal.
This is the config file and bash script below:
getPatches.cfg
SERVERLIST="server1;server2"
USERNAME=bob
DIRECTORY=/net/bob
bash script
#!/bin/sh
CFGFILE=getPatches.cfg
if ! [ -f $CFGFILE ] ; then
echo "ERROR: $CFGFILE configuration file is missing"
exit 1
fi
# READ $CFGFILE
. $CFGFILE
servers=$SERVERLIST
user=$USERNAME
directory=$DIRECTORY
#Tokenize ServerList
while IFS=';' read -ra ADDR; do
for i in "${ADDR[@]}"; do
ssh $user@$i
AccessIntoDirectory="cd $directory"
export AccessIntoDirectory
ssh -q $i $AccessIntoDirectory
done
done <<< "$servers"
I've generated a SSH public key and what this script should do is to SSH into the server and cd into the directory that I want, but it exited instead and did not SSH into the server. Any help would be great!
不使用控制台（tty）而使用ssh命令的解决方案是添加-t -t选项。
ssh -t -t $user@$i
At first check the line
ssh $user@$i
It does not supply a command, so your script tries to start an interactive shell on the remote host. That's where you get the error from.
Secondly I'd like to check if you accidently used backticks `` instead of ticks '' or double quotes "" in the line with
`AccessIntoDirectory=`cd $directory`
which would falsely run the 'cd' command and assign it's output to the variable.
