SSH mutual trust Configuration

SSH mutual trust Configuration

Specific Configuration:

Disable iptables and SELinux

1. Open the ssh configuration file and enable the following options:

Vim/etc/ssh/sshd_config

RSAAuthentication yes # Allow RSA Authentication

PubkeyAuthentication yes # Allow Public Key Authentication

AuthorizedKeysFile. ssh/authorized_keys # public key storage address

# PermitRootLogin yes if you want to log on as a root user using ssh mutual trust, do not enable this project.

2. Restart the ssh service.

/Etc/init. d/sshd restart

3. Generate the public key and private key:

Ssh-keygen-t rsa-P ""

-P indicates the password, and-P "" indicates that the password is empty, or you do not need the-P parameter. In this case, you have to press enter three times and press enter once with-P.

The default value is ~ /. The ssh directory generates two files, Private Key id_rsa and Public Key id_rsa.pub.

4. Import the public key to the authentication file and change the permission.

2.1 import to the authorized_keys file of the Local Machine (for backup)

Cat ~ /. Ssh/id_rsa.pub> ~ /. Ssh/authorized_keys

2.2 import to the authorized_keys file for password-free login to the server

First, copy the public key to the server.

Scp ~ /. Ssh/id_rsa.pub xxx @ host:/home/id_rsa.pub

Then, import the public key to the authentication file (this step is performed on the other server)

Shell code: cat/home/id_rsa.pub> ~ /. Ssh/authorized_keys

2.3 Change permissions on the server

Chmod 700 ~ /. Ssh

Chmod 600 ~ /. Ssh/authorized_keys

5. Test Logon

Ssh 192.168.111.111

If ssh is not the default port, add the-p port number after the ssh command.

For example:

Ssh-p 10000 192.168.111.111

6. Disconnect ssh Login

Exit

7. multiple servers have mutual ssh trust. Only the above operations can be performed on multiple servers.
