Answer 1

Of course you can. I currently use Cloud Helper to manage Alibaba Cloud servers, which is pretty good. It can perform 24-hour basic monitoring of the server from four aspects: CPU, memory, disk, and network.

Answer 2

Yes, I recommend an artifact that should be able to help you. Cloud Helper is a powerful and comprehensive centralized management cloud host software. Not only is it compatible with Linux systems, Windows can also be used. In fact, the use of functions is quite good, because the functions are comprehensive and the installation is simple. Basically, it can be done with one click by a fool. If you add a cloud host in the middle, you need to add a probe for the first time, and then you can basically operate it on the panel. This is quite convenient. I have tried basically all the mainstream clouds and there are no problems, and there are no problems with the system. This is quite worry-free. I won’t say that there are any cloud providers or systems that cannot be used, and I have to find another software. The general functions are as follows: 1. Batch management of multiple cloud hosts; 2. Strong compatibility, compatible with basically all cloud business cloud hosts on the market, and compatible with operating systems; 3. Simple operation, visual interface preview resources, one-click repair, one-click deployment ; 4. You can remotely log in to the FTP desktop of the cloud host and process files on the cloud host; 5. Monitoring and resources also have an alarm function, which is very good, and you don’t have to stare at it; 6. System repair function, this is very practical It is also quite necessary; 7. Free to use. Generally speaking, the functions are quite complete, and there is no need to find another software. A cloud helper software basically meets all needs.

Answer 3

My server is like this. One entrance server has an external IP, and several servers only have an internal IP

First configure the ssh of the entrance server to use the key to log in without a password, and then modify the local ~/.ssh/config

# 入口服务器
Host gateway
    HostName 192.168.0.2
    User root

# 内网服务器
Host foo
    HostName 192.168.0.3
    User root
    ProxyCommand ssh -NW %h:%p gateway

# 内网服务器
Host bar
    HostName 192.168.0.4
    User root
    ProxyCommand ssh -NW %h:%p gateway

This way you can use ssh foo to directly manage the intranet server without having to ssh to the gateway first and then ssh to foo from the gateway

Answer 4

Yes, with one Alibaba Cloud account, machines in the computer room can access each other

Answer 5

Yes, this is a similar large-port server as the front-end, and you can buy a high-performance back-end

Answer 6

Answer 7

Now the same node between different accounts can be accessed by configuring the rules of the security group.
