Free Whoring IBM LinuxOne Tutorial
1 Introduction
1.1 Preface
LinuxONE Community Cloud is a platform provided by IBM and Marist University for students to test applications and websites, providing free VPS for up to 120 days.
Warm reminder: This VPS is based on the S390X architecture, and its compatibility is not as good as that of the x86-64 or arm architecture. There are not many softwares that can be installed. This machine is more suitable for building a website. LNMP, LAMP, Pagoda, etc. can run, and the performance and concurrency are also good. It is quite strong, and it is also very good to be a compiler. If you are mining,
there is a high probability that it will not work, and the terms do not allow it . If you are highly skilled, you can try to compile xmrig yourself.
It is not recommended that you use this thing to build a proxy tool. It is easy to seal the number , but this machine
can indeed set up a Minecraft server, but the delay will be relatively high
1.2 configuration

2. Basic preparation
- An email address, GMail is recommended, domestic QQ, etc.
- English basics, if you don't understand English, please use the browser translation plug-in
- Linux basics
3. Application examples
Official website link: address
Click to jump to the official website to register.
You need to fill in some basic information. You can fill in your own information, or use an American information generator to generate it. Just fill in "Machine Learning" and "develop website" for the reason for the application. If the description is unclear, it may not be approved.
American Information Generator URL: Generator
For example I generated
Well, in order to demonstrate the effect, I registered another qq and opened a qq mailbox.
Confirm by email:
After successful registration, log in with the account password you just registered, and you will enter the following page after successful login.
Click Manage Instance
Click Create:
Here I chose RHEL8.4, all can be.
Click create to create a key, a key pair will be generated, and a pem file will be downloaded. That is the key in the figure above.
Select the key you just generated, and click Create in the lower right corner.
Then the instance state will last for a period of time during spawning.
When the instance is active, you can use the Xshell link.
4. Instance configuration
4.1 Remote connection
I use the Xshell tool, create a new session, enter the instance ip, select the public key mode, enter the user linux1, and click OK.
Note: Xshell4 cannot be connected (pro-test), and it will prompt that the encryption method is not supported. I downloaded Xshell7
There will be SSH security warnings:
Click Accept and Save, and select the key you just generated.
Click OK to connect to the server remotely.
In this way, only the Linux1 user is logged in, and he does not have permission to operate many files. So get the root user to operate.
4.2 Configure root user
Switch to root account
sudo -i
Set root password (can be skipped)
passwd
Open the ssh configuration file
vi /etc/ssh/sshd_config
Modify or add the following configuration
PermitRootLogin yes
PubkeyAuthentication yes
Right now:
Finally edit the authentication file authorized_keys
vi /root/.ssh/authorized_keys
put two
no-port-forwarding,no-agent-forwarding,no-X11-forwarding,command="echo 'Please login as the user \"linux1\" rather than the user \"root\".';echo;sleep 10;exit 142"
are deleted. Then save wq and exit, so that you can create a new session and log in with the root account.
4.3 Configure httpd service
Install gcc-c++
yum install -y gcc gcc-c++
install httpd
yum install httpd -y
httpd command
systemctl start httpd.service #启动 或者 service httpd start(下面同理)
systemctl stop httpd.service #停止
systemctl restart httpd.service #重启
Set boot
systemctl enable httpd.service #开机启动
systemctl disable httpd.service #开机不启动
check httpd status
systemctl status httpd.service
Check firewall status
systemctl status firewalld 或者service firewalld status
#如果没有关闭，关闭即可
systemctl stop firewalld 或者 service firewalld stop
At this time, you should be able to access it. If you still don’t have it, just restart the server.
5. Domain name configuration
Open cloudflare, find DNS, and configure the host ip just now to springmvc.tk. The ip here is different from the previous picture because something went wrong, and I reinstalled the system.
Finally, let's take a look at the effect.
