To achieve passwordless login on a CentOS system, you can follow these steps:<\/p>\n

    \n
  1. Generate SSH key pairs locally. Run the following command on your local terminal to generate SSH key pairs:<\/li>\n<\/ol>\n
    ssh-keygen\r\n<\/code><\/pre>\n
    Following the prompts, the key pair will be generated in the ~\/.ssh\/ directory.<\/p>\n
      \n
    1. Copy the public key to the target server. Execute the following command to copy the local public key to the target server:<\/li>\n<\/ol>\n
      ssh-copy-id username@hostname\r\n<\/code><\/pre>\n
      The username is the username for the target server, and the hostname is the address of the target server.<\/p>\n
        \n
      1. Verify passwordless login. Try connecting to the target server using SSH, if all settings are correct, you should be able to login directly without entering a password.<\/li>\n<\/ol>\n
        ssh username@hostname\r\n<\/code><\/pre>\n
