一 创建秘钥 1 Macbook $ ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key ($HOME/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in $HOME/.
官方:https://www.ssh.com/ssh/ The SSH protocol uses encryption to secure the connection between a client and a server. All user authentication, commands, output, and file transfers are encrypted to protect against attacks in the network. 密钥类型包括rsa和dsa,
这里以三台mysql的主从服务器为例:manage.master.slave1.slave2 给4个机器生成秘钥文件 以manage为例,执行命令,生成空字符串的秘钥(后面要使用公钥),命令是: [root@manage ~]# ssh-keygen -t rsa -P '' Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created dir
