1，打开xshell  --工具---新建户名秘钥

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70 1][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70 2][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70 3][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70 4][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70 5][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70 6][]

2.打开刚刚生成的公钥  文本编辑打开，全选复制代码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2p4eWsyMDA3_size_16_color_FFFFFF_t_70 7][]

cd /root/.ssh/  
    
    
    创建编辑
    vi id_rsa.pub  
    粘贴刚刚生成的秘钥
    保存--退出
    
    cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
    将上面生成的公钥id_rsa.pub追加到authorized_keys文件中

[root@localhost .ssh]# ls
    authorized_keys  id_rsa.pub  known_hosts
    [root@localhost .ssh]# chmod 600 /root/.ssh/authorized_keys
    [root@localhost .ssh]# cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
    [root@localhost .ssh]# cat authorized_keys 
    ssh-rsa AAAAB3Nz000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000yWQY6mRx4t5/Qx0JRnZJU5/UGR2n11I9S/FGHTOnkzAyUUfUOuXCn76q29JW9SKaVEXKQJJp9OFETZFqfbQ7uEiPfbw==
    [root@localhost .ssh]#

3.新建连接 输入服务器地址使用秘钥登录
