1、先按照文档在本地生成SSHkey
2、mac输入 sudo -i 进入超级管理员#模式下，然后
创建用户
#useradd XXXadmin
#passwd XXXadmin
XXXadmin用户增加授权key
cd /home/XXXadmin/
mkdir .ssh
chmod 700 ~/.ssh
把本地的key ：XXXadmin.pub上传到 .ssh 下 并重命名为：authorized_keys
chmod 600 authorized_keys
修改用户组
chown -R XXXadmin:XXXadmin ./.ssh
编辑ssh 配置文件
vi /etc/ssh/sshd_config
去掉下面三行注释
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
修改
Port 5555
PermitRootLogin no
PasswordAuthentication no //禁止使用密码登录
service sshd restart
~~~~~~~~上传文件到服务器，下载服务器文件到本地~~~~~~
1.本文主要是采用scp 来进行复制
abc@abcs-Mac:~$ scp -h
scp: illegal option -- h
usage: scp [-346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
[-l limit] [-o ssh_option] [-P port] [-S program]
[[user@]host1:]file1 ... [[user@]host2:]file2
OPTIONS：
-v 和大多数 linux命令中的-v意思一样，用来显示进度。可以用来查看连接、认证、或是配置错误
-C 使能压缩选项
-P 选择端口
-r 复制目录
1、从本地将文件传输到服务器
scp【本地文件的路径】【服务器用户名】@【服务器地址】：【服务器上存放文件的路径】
abc@abcs-Mac:~$ scp -P /Applications/program/HTTP请求.jmx lilyadmin@xxx.xx.xx.xxx:/home/lilyadmin/
HTTP请求.jmx % .4KB/s :
2、从本地将文件夹传输到服务器
scp -r【本地文件的路径】【服务器用户名】@【服务器地址】：【服务器上存放文件的路径】
scp -r -P /Applications/program/test11 lilyadmin@106.xxx.xx.xxx:/home/lilyadmin/
3、将服务器上的文件传输到本地
scp 【服务器用户名】@【服务器地址】：【服务器上存放文件的路径】【本地文件的路径】
scp -v -P 5555 lilyadmin@xxx.xx.xx.xxx:/home/lilyadmin/1.txt /Users/abc/
4、将服务器上的文件夹传输到本地
scp -r 【服务器用户名】@【服务器地址】：【服务器上存放文件的路径】【本地文件的路径】
scp -r -v -P lilyadmin@xxx.xx.xx.xxx:/home/lilyadmin/test /Users/abc/
Executing: program /usr/bin/ssh host 106.xxx.xx.xxx, user lilyadmin, command scp -v -f /home/lilyadmin/.txt
