This article will introduce some basic knowledge in linux deployment.

How to connect to the linux server and tranfer files to linux server

1. We commonly use the ssh command to connect to server.

   1 2 3

   ssh username@hostname #example ssh root@192.168.0.2

• The first name you login, you will be noticed:

1

3

The authenticity of host '10.0.0.1 (10.0.0.1)' can't be established.
ECDSA key fingerprint is SHA256:iy237yysfCe013/l+kpDGfEG9xxHxm0dnxnAbJTPpG8.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

input yes is ok.

• You can save the server info in the configure file Modify the ~/.ssh/config or /etc/ssh/ssh_config file in order to store information of servers.

  1 2 3 4 5 6 7 8

  Host host1 HostName IP Address or DomainName User foo Host host2 HostName IP Address or DomainName User foo IdentityFile ~/.ssh/foo.key

After being configured, just login by

2

ssh host1
ssh host2

• Two ways login in ssh ### By key

  The way to create ssh key

  1	ssh-keygen

  After being executed, you will find id_rsa and id_rsa.pub two directories under ~/.ssh/.

  And then copy the .key file path to the IdentityFile configure I mentioned above.

  ### By password

transfer file from your local to linux server by scp

1. We can transfer file from source to destination as below

   1 2 3

   scp source destination #example scp ./a.txt root@10.0.0.2:/usr/local

   The file above means transfer ./a.txt file to folder /usr/local of the server 10.0.0.2 .

2. transfer multiple files

3

scp source1 source2 destination
#example
scp ./a.txt ./b.txt root@10.0.0.2:/usr/local

3. transfer folder

scp -r source_folder destination
#example
scap -r ./folder1 root@10.0.0.2:/usr/local
