linux中控操作相关

1、首先生成无密码登陆密钥一般使用rsa

2、编写shell脚本

work_dir=$(pwd)
   ssh -p${port} -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no ${host_prefix}$1

3、远程拷贝

work_dir=$(pwd)
for i in {2..9}
do
  scp -P20755 -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -r $1 ￥{host_prefix}$i:$2
  echo
done

4、远程执行命令

work_dir=$(pwd)
for i in {1..9}
do
   ssh -p20755 -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no ￥{host_prefix}$i "cd $work_dir; $@"
done
