我想设置从本地计算机到此Linux服务器的无密码登录。当我尝试上传我的公钥时，我发现服务器上没有.ssh。所以我在服务器上用ssh-keygen创建了一个。但是在新生成的.ssh目录中，没有authorized_keys或known_hosts。所以我创建了一个新的authorized_keys并从本地机器上粘贴了我的公钥。但是它不起作用，仍然需要ssh的密码。谁能告诉我，我做得对吗？
这是ssh -vvv的输出：

只需创建它并将密钥复制到它。如果您有密钥复制工具，则只需通过
创建文件$ touch ~/.ssh/authorized_keys
使用该工具之前。
使用-vvv连接可能有助于详细说明。
在客户端和服务器上，检查〜/ .ssh是否具有权限700。
在服务器上，检查/etc/ssh/sshd_config是否有：
AuthorizedKeysFile .ssh/authorized_keys
PubkeyAuthentication yes
RSAAuthentication yes
