ansible 学习难点攻克

昨天进行了ansible的学习。使用服务器已经由同事安装完成。

在执行

ssh-copy-id wang@XXX.xx.xxx时报错。

Jenkins:~ jenkins$ ssh-copy-id root@xxxx
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/jenkins
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filt
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are pro
Permission denied (publickey).

 

错误原因：ssh在没有密钥登录的情况下，禁用了密码登录，故出现如上错误。

 

解决办法：

登录服务器，将/etc/ssh/sshd_config文件中的PasswordAuthentication no 改为PasswordAuthentication yes

重启sshd服务：/etc/init.d/ssh restart

再次执行：

Jenkins:~ jenkins$ ssh-copy-id wang@xxxx
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/jenkins/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys

wang@119.23.241.8's password:

输入密码即成功。

输入ssh wang@xxxxx  则登录我的服务器成功
