Linux Learning Notes (iii) Putty, Xshell application

The previous section learned the static IP configuration of Centos7, and today learns to use putty and Xshell remote connections CENTOS7
First, learn to use putty.
1. Download the Putty Package
Https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

• Then install putty, here not too much to repeat, open putty
  
  * Fill in the box with your own IP 192.168.40.133, and a name in the bottom box chinantfy-01
  Then left click on translation Select Utf-8, go back to session click Save, then click Open (Before you start the virtual machine Centos7)
  
  
• The first link will appear a pop-up window, click Yes
  
• enter root, and then enter the password, the login succeeded
  
  2. Learn to use Putty Key link Centos7
  Start menu Puttygen
  
  Open and click Generate Generate secret Key
  
  
  
  * Password can be empty or input, here is the test, I temporarily do not set the password, the above box of the public key is selected to copy, first saved to a text, and then click on the two save below, save the public key and the private key, and remember the name;
  Next, put the public key into Linux,
  Create the/root/.ssh folder first, and if it is another user, the file path is/home/user name/.ssh

    mkdir/root/.sshchmod 700/root/. Sshvi/root/.ssh/authorized_keys  

  This step is to create a file holding the public key, after executing the above command, press I into insert mode, copy the public key just saved, ESC exit Insert mode: Wq Save and exit
  
  Next close selinux

    vi/etc/selinux/config  

  
  Change selinux after enforcing to disabled, Save and exit, enter init 6 restart Centos7
  
  
  Close putty reopen
  Click on the chinantfy-01 and then click Load
  
  next to the left Auth
  
  Select the name of the private key you just saved
  return to session Click Save to save the configuration, Open Putty window
  Enter the username root,
  
  because no password was previously set, directly landed Centos7
  The above is the use of Putty connection Centos7 method, user name plus password login and secret key login
  two. Xshell connection centos7
  1 First download Xshell
  https://www.netsarang.com/ products/xsh_overview.html
  Open after installation
  

Click the tools above to create a new user key Generation wizard


Fill in the Key name and password, my name here is the default, the password is left blank

As with the previous putty, save the public key copy all

2. Next, learn Xshell's account password link centos7

Click the top left corner to create a new

Name customization, host fill IP address

Point left terminal, encoding select Utf-8

Click Connect user authentication, enter Centos7 's account number, password,
Select the chinantfy-01 connection you just created when you're done
The first connection will also pop the window, choose to accept and save

It's a good landing here,
3. The above learned Xshell user password connection, and key pair generation, next learn to use the secret key connection Xshell
Input
vi /root/.ssh/authorized_keys
Edit the secret key file again

I enter into the insert mode, the public key that just created with Xshell is copied in, here I for the future good distinction, separately added notes

ESC exits insert mode: Wq Save and exit
Click the plus sign in the upper left corner of Xshell
Right-click on the Chinantfy-01 property

User authentication, method Select Public key, user key Select the key you just generated and click OK

Because there is no login password to set the key, so directly to the root user connected to the CENTOS7;
The above is the use of Putty and Xshell connection Centos7 methods and procedures, it is important to note that the public key to replicate accurate, Vi/root/.ssh/authorized_keys this command and file path to be accurate, the beginning of practice because of not careful, These two problems often go wrong, be sure to pay attention to.
