SSH public key verification
It is not safe to log on to the server using the username and password. The SSH public key is used to verify that this method can effectively solve the login server and secure login server features:Objective: to log on to the Server by using Client password-free sshSSH supports multiple logo
First, IntroductionAnsible is strong in the playbooks, but in order to use the playbooks very well, we must first have some foundation. such as: How to write a one-time script command? How do you know which modules are available? How are each module used? such asWith this article, you can learn how to use one-time commands and some modules.After installing Ansible, to get started, you also need to create a list of controlled hosts. Default Read/etc/an

Step two: Login with secret key
Because we are ready to test SSH key landing, to see if the setting is successful, if not successful can also login password, so the modified must be tested, for the VPS provider to provide console, it can be arbitrary, after all, there are console can be used

Generate SSH Public keyMost Git servers will choose to use the SSH public key for authorization. Each user in the system must provide a public key for authorization, and none will generate one. The process of generating the public key is similar on all operating systems. Fir

Create key login certifications with SECURECRTFirst, generate a public/private keyUsing the SecureCRT tool, create the public key, the encryption algorithm chooses RSA, because the RSA configuration file is selected in the algorithm.Pass phrase can not be entered. However, you will be asked to enter a passphrase when you log in.and modify comment related information, using the personal account name @ Server

If we manage enough servers, it is not difficult to enter the password every time. Here we have a proxy method ssh-agent, the ssh-agent is actually a key manager. It can also be understood as a butler. we hand over the key to the butler to keep it. Every time we open the door, the butler will help us open the door and
1. if ssh is not installed, run the following command:
Sudo apt-get install ssh
2. Check the SSH public key.

Check whether the. ssh file exists. If the file exists, mov
does not have the blue private key. There are always problems, and there are always solutions. SSH provides the forwarding key function, so we can jump from the local machine to the stepping stone machine to forward the private key.
Therefore, the correct method is to execute commands on the local Linux client.

If the checksum is correct, a new

When Fabric is used, if a large number of servers are used for processing, we need to configure the host password. The password of each host is the same, but different, you need to configure different hosts. The following two configuration methods are available:
