ec2-userをパスワード認証にする

Last updated at Posted at 2019-12-04

公式に書いてある通りではうまくいかず
一味加える必要があったゾ…(PubkeyAuthentication no)

# #ec2-userにパスワードを設定する
# sudo passwd ec2-user

# #sshd_configをちょっといじる必要がある
# sudo vim /etc/ssh/sshd_config
-----------------------------------------------------------
PasswordAuthentication yes 	#パスワード認証を有効化
PubkeyAuthentication no 	#鍵認証を無効化
-----------------------------------------------------------

# #sshdを再起動しないと有効にならない
# sudo service sshd restart

# #リログして確かめるゾ~
# exit

#追記:↑を設定したEC2インスタンスのAMIに問題が…
そのAMIから起動したインスタンスがSSHログイン不能に /(^o^)\

とりあえずAMI化する際には

PubkeyAuthentication yes

に戻さねばという情けない状態…

今度時間あるときに詳しく調査ゾ…
