Question

为什么在单台服务器上完成任务（列表顶部）后循环就自己结束了？ 下面的脚本用于读取ftp-user-and-pass.txt文件并将凭据分配给var，并使用SSH执行远程命令。

script.sh

#!/bin/bash
count=0
while read info
do
    let count=$count+1
    ip=$(echo $info | cut -d' ' -f1)
    echo "********************************************"
    echo "Executing on server $count ssh: remoteuser@$ip"
    user=$(echo $info | cut -d' ' -f2)
    pass=$(echo $info | cut -d' ' -f3)
    echo "user:$user pass:$pass"
    echo " using remote ssh execution"
    ssh -tt -T -i /home/remoteuser/ssh.key remoteuser@$ip "/bin/bash <<-'EOF'
 ##
 #  commands inside ssh session on remote server
 ##
    rm mount.sh*
    wget http://******.*******.com/scripts/mount.sh > output.txt
    sleep 4
        sudo chmod a+x mount.sh
    sudo ./mount.sh -v -u $user -p $pass >> output.txt
    cat output.txt
    exit
        EOF"    
    echo "Remote mount execution completed for:"
    echo "$info"
    echo "" 
done < /home/remoteuser/ftp-user-and-pass
echo "$count"

此脚本用于在/ opt / remote_backup_server /

上安装远程ftp服务器。

mount.sh

此凭证文件包含服务器ip，ftp用户，ftp传递

ftp-user-and-pass.txt
