ubuntu hadoop 环境创建ssh无密码登录 localhost
这几天在自己的ubuntu机器上,研究sector/sphere,突然发现我原来在公司配置ssh无密码登录的办法无效,后来搜索后知道了原因,现将ubuntu上设置ssh无密码登录的步骤列出来:
步骤
1.创建密钥
~/.ssh$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): (忽略)
Enter same passphrase again: (忽略)
Your identification has been saved in /.ssh/id_rsa.
Your public key has been saved in /.ssh/id_rsa.pub.
2.添加公密到信任列表
~/.ssh$ cat 192.168.1.110 >> authorized_keys
~/.ssh$
3.启动ssh-agent (以前没有做过的步骤)
如果ssh localhost返回这样的提示
Agent admitted failure to sign using the key
ps -aux|grep agent查看有无ssh-agent有无运行,若没有
~/.ssh$ ssh-agent
4.添加id_rsa到ssh-agent
~/.ssh$ ssh-add id_rsa
