ssh公钥登录
原因 通过密码进行ssh连接存在被暴力破解的可能,但在禁用密码登录+修改22端口+禁用root登录之后,可以将被暴力破解的概率降到最低,且通过private_key登录服务器更适合shell操作 生成公钥,私钥 下面以ubuntu18.04为例 #( 09/27/18@11:30上午 )( lestat@lestat-MS-7A15 ):~/Desktop ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/home/lestat/.ssh/id_rsa): /home/lestat/.ssh/vps Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/lestat/.ssh/vps. Your public key has been saved in /home/lestat/.ssh/vps.pub. The key fingerprint is: SHA256:rcD6QAPXaRrDfNMR1MdQu/s4TvEtOlumK3AUcdzrUaM lestat@lestat-MS-7A15 The key's randomart image is: +---[RSA 2048]----+ | .+oo*o. | | o . o .o.+....| | . * * . o. .o.| | o B . ..
