Alibaba Cloud Server Mac connects to Alibaba Cloud Server

1. Connect to the Server through the command line and set up

　　1.1 Connect to the Server

#: ssh root@hctec.top

ssh: Remote connection tool

root: Remote server user name, here I use: root user

hctec.top: is the domain name of the server, of course you can use IP directly

1.2 Directly connect to the Server without a password (we use ssh -copy-id tool, perform key verification)

#: brew install ssh-copy-id

#: ssh-copy-id root@hctec.top

　　　 brew: brew again Called Homebrew, it is a software package management tool on Mac OSX. It can easily install or uninstall software on Mac. It only requires one command, which is very convenient. Reference: brew installation and use

　　　　 brew is similar to apt-get under the ubuntu system Functions

2. ECS instances:

　2.1 Instance snapshot

　 Personal understanding: It can be used as a backup of the system. When the system encounters an irreparable operation, the system can be restored by rolling back the instance;

　2.2 System image

　We can make a system image based on the snapshot of the system disk, so that we do not need to repeatedly configure the server.

　2.3 Security Group

　Specified intranet & public network access Rules
