一个很有用的脚本,记录一下,具体用法不介绍了

cat ssh-copy-id

#!/bin/sh

 
# Shell script to install your identity.pub on a remote machine

# Takes the remote machine name as an argument.

# Obviously, the remote machine must accept password authentication,

# or one of the other keys in your ssh-agent, for this to work.

 
ID_FILE="${HOME}/.ssh/identity.pub"
 
while getopts ':i:p:P:h' OPTION
do
    case $OPTION in
        i)
        if [ -n "$OPTARG" ]; then
            if expr "$OPTARG" : ".*.pub" > /dev/null ; then
                ID_FILE="$OPTARG"
            else
                ID_FILE="$OPTARG.pub"
            fi
        fi
        ;;
        P|p)
            PORT=$OPTARG;
        ;;
        h)
            echo "Usage: $0 [-i [identity_file]] [user@]machine" >&2
            exit 1
        ;;
    esac;
done;
 
shift $(($OPTIND - 1))
 
if [ $# -lt 1 ] && [ x$SSH_AUTH_SOCK != x ] ; then

   GET_ID="$GET_ID ssh-add -L"
fi
 
if [ -z "`eval $GET_ID`" ] && [ -r "${ID_FILE}" ] ; then
  GET_ID="cat ${ID_FILE}"
fi
 
if [ -z "`eval $GET_ID`" ]; then
  echo "$0: ERROR: No identities found" >&2
  exit 1
fi
 
if [ -z $PORT ]; then
    PORTOPTION=""
else
    PORTOPTION="-p $PORT "
fi;
 
{ eval "$GET_ID" ; } | ssh $PORTOPTION $1 "umask 077; test -d .ssh || mkdir .ssh ; cat >> .ssh/authorized_keys" || exit 1
 
cat <<EOF
Now try logging into the machine, with "ssh $PORTOPTION'$1'", and check in:
 
  .ssh/authorized_keys
 
to make sure we haven't added extra keys that you weren't expecting.
 
EOF


# ssh-copy-id -i ~/.ssh/id_rsa.pub "-p 22222 "

这个脚本安装ssh会自带的。
