创建ssh密钥
创建SSH密钥
SSH密钥允许您在不必每次输入密码的情况下访问安全的远程服务器。有几个步骤可以创建SSH密钥。
首先打开终端或命令行并输入以下命令：
ssh-keygen
您将被问及存储SSH密钥的位置。您可以选择默认位置或指定其他位置。在选择位置时请记住您将需要访问该位置以便在将来的日期与远程服务器通信。
接下来您将被要求输入密码短语。这是您的SSH密钥的密码因此请确保其足够安全。
一旦完成上述步骤您的SSH密钥将创建在指定位置。
添加SSH密钥到您的服务器
将SSH密钥添加到您的服务器上使您能够通过SSH协议远程访问服务器而不必输入密码。
首先将公共密钥内容复制到剪贴板中以便稍后粘贴到服务器上。
cat ~/.ssh/id_rsa.pub
将此命令返回的公钥复制并在服务器上打开终端。然后将此公钥附加到以下文件中：
~/.ssh/authorized_keys
如果以下文件不存在则需要手动创建它：
mkdir -p ~/.ssh
touch ~/.ssh/authorized_keys
测试您的新SSH密钥
现在您已经创建并添加了SSH密钥可以测试它是否正常运行。
在终端或命令行中输入以下命令：
ssh user@hostname
其中user是您的用户名hostname是您要访问的远程服务器的名称或IP地址。
如果您成功地连接到远程服务器而不必输入密码则您的SSH密钥已经成功创建并配置。
Creating an SSH Key
An SSH key allows you to securely access remote servers without having to enter a password each time. There are several steps to creating an SSH key.
First, open your terminal or command prompt and enter the following command:
ssh-keygen
You will be prompted to choose a location to store your SSH key. You can choose the default location or specify a different location. When choosing a location, keep in mind that you will need to access this location in the future to communicate with remote servers.
Next, you will be asked to enter a passphrase. This is the password for your SSH key, so be sure to make it secure.
Once the above steps are complete, your SSH key will be created at the specified location.
Adding Your SSH Key to Your Server
Adding your SSH key to your server allows you to remotely access the server via the SSH protocol without having to enter a password.
First, copy the contents of your public key to your clipboard so that you can paste it onto the server later.
cat ~/.ssh/id_rsa.pub
Copy the public key returned by this command and open your terminal on the server. Then, append this public key to the following file:
~/.ssh/authorized_keys
If this file does not exist, it needs to be manually created:
mkdir -p ~/.ssh
touch ~/.ssh/authorized_keys
Testing Your New SSH Key
Now that you have created and added your SSH key, you can test to see if it is working properly.
In your terminal or command prompt, enter the following command:
ssh user@hostname
Where user is your username and hostname is the name or IP address of the remote server you are trying to access.
If you successfully connect to the remote server without having to enter a password, then your SSH key has been successfully created and configured.
