Linux配置远程SSH无密码登录--1号站长-站长学院|资讯交流平台

本文实例为大家分享了jaLinux配置远程SSH无密码登录的方法，供大家参考，具体内容如下

系统：CentOS 6.8
主机1：192.168.0.177
主机2：192.168.0.178
工具介绍：
ssh-keygen：创建公钥和密钥
ssh-copy-id：把生成的公钥复制到192.168.0.178主机上的authorized_keys文件上，
ssh-copy-id也会给远程主机的用户主目录（/home）和/root/.ssh和/root/.ssh/authorized_key设置合适的权限

1）创建公钥和密钥

[root@test ~]# ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/root/.ssh/id_rsa):Enter passphrase (empty for no passphrase):Enter same passphrase again:Your identification has been saved in /root/.ssh/id_rsa.Your public key has been saved in /root/.ssh/id_rsa.pub.The key fingerprint is:79:a9:66:cd:1a:a5:7c:82:80:c3:06:ec:44:13:b9:7a root@testThe key's randomart image is:+--[ RSA 2048]----+| +o ||o.. ||.o. ||o+ . . . ||..= .
