Linux SSH alias login tips _linux

In order to facilitate login to the server, we generally use putty, securecrt and so on tools. How does a terminal log on through a server alias?

You can create ~/.ssh/config files and specify logon information and authentication methods for each server, as follows:

$ vim ~/.ssh/config

Host www
  HostName www.ttlsa.com
  Port
  User root
  identityfile ~/.ssh/id_ Rsa.pub
  identitiesonly Yes

Host bbs
  HostName 115.28.45.104
  User anotheruser
  Pubkeyauthentication No

Then specify the alias directly to sign in

Shell
$ ssh www
1 $ ssh www
Option Note:

HOSTNAME Specifies the host name or IP address of the login
PORT Specifies the port number of the login
User logon username
Identityfile Log in Public key file
Identitiesonly only accept SSH key login
Pubkeyauthentication
