13. Experience CVM of CentOS system

Cloud server (Cloud Virtual Machine, CVM) provides you with secure and reliable elastic computing services. In just a few minutes, you can acquire and enable CVM in the cloud to meet your computing requirements.
Experience CVM with WebIDE

Access directly in browser Website

Select Region (currently only one Hangzhou can choose)

Create a Host, execute a command on your machine to install ide agent to achieve the effect

1. Click the "+" sign in the Hosts view to create a Host, copy the commands in the dialog box and execute them in the local command line terminal.

2. After successful execution, the command will output a prompt message, in which you will be prompted to add the PATH / Users/kevin/.ide_home/bin, 
/Users/kevin/.ide_home/bin is my local path. Your path will be a little different from mine, whichever you see,
The ide start command can only be executed after it is added to the PATH correctly, otherwise the command will be reported as no error
 (there will be differences in the path under windows system, mainly the content output by the console).

3. Next, run the command ide start on the local command line terminal to start the IDE agent service. At this time, on the WebIDE interface,
You can see that the host icon turns green (green icon indicates that the host is online, gray indicates that the host is offline).

4. Return to the WebIDE interface, click OK in the dialog box or click refresh in Hosts view to see your newly registered host.

Be careful:

Currently supports Mac and Linux, Windows 10 Pro, Enterprise, or Education.

Because the environment depends on docker and docker compose, it needs to be installed in advance.
Where docker version > = 1.13.0, docker compose version > = 1.11.0.

Modify PATH on Mac and Linux systems. If the shell is bash, you can modify the file ~ /. bashrc, and append PATH=$PATH:/Users/kevin/.ide_home/bin to the end of the file ~ /. bashrc. If the shell is zsh, you can modify ~ /. zshrc. /Users/kevin/.ide_home/bin is my local PATH. Your PATH will be a little different from mine, subject to what you see. If it is Windows, you need to set the environment PATH.

17. Build wechat applet service

There is no doubt that applets are a major hot spot on the Internet this year. This experiment takes you from scratch to build a service based on NodeJS that can support the running of applets, including HTTPS deployment, session service and WebSocket service. Finally, use these services to realize a real-time scissors and stone cloth game.

18. Build wechat AI robot

This experiment takes you step by step to realize WeChat AI robot. During this period, it introduced the application of official account, application robot, how to configure the official account background, how to call robot API and so on.

19. Set up wechat subscription number background service

WeChat official account background Sometimes our own functions may not meet our needs. At this time, we need to build our own server.

Apply for wechat personal subscription number

register Developer account (three fields need to be obtained: AppID, Token and EncodingAESKey)
① AppID: log in to wechat public platform and enter development basic configuration in turn to get AppID

② In the basic configuration server configuration modify configuration form
URL fill in the domain name applied in the first step;
The Token user fills in according to the prompt, which is used to later verify the validity of the server;
EncodingAESKey click the random Build button to generate

Build HTTP service (use Node and Express to build an HTTP server)

Install NodeJS and NPM

curl --silent --location https://rpm.nodesource.com/setup_8.x | sudo bash -

yum install nodejs -y

Write HTTP Server source code (add the name and version number of the server package)

mkdir -p /data/release/weapp

cd /data/release/weapp

vim package.json
{
    "name": "weapp",
    "version": "1.0.0"
}

Add Server source code

vim app.js
// Quote express To support HTTP Server Implementation
const express = require('express');

// Reference wechat public platform automatic reply message interface service middleware
var wechat = require('wechat');

// Create a express Example
const app = express();

// Configure wechat public platform parameters, and obtain them in the second step of the tutorial
var config = {
    token: 'youadminwen', // Fill in the `token`
    appid: 'wx52843a03b58edc4c', // Fill in the `appid`
    encodingAESKey: 'e31T2gWV6mBsSu1Dut8ufDPs1VlgooGIyoej2pa0IOc', // Fill in the`encodingAESKey`
    checkSignature: true // Optional, default is true. Since wechat public platform interface debugging tool does not send signature in clear text mode, please set it to false 
};

app.use(express.query());

app.use('/', wechat(config, function (req, res, next) {
    res.reply({
        content: 'Hello, Hello World!',
        type: 'text'
    });
}));

// Listening port, waiting for connection
const port = 5050;
app.listen(port);

// Output server startup log
console.log(`Server listening at http://127.0.0.1:${port}`);

Install PM2

npm install pm2 --global

Installing Express

npm install express --save

20. Building Discuz Forum

Discuz It is a forum tool based on PHP web page, which can be deployed on both Linux and windows platforms.

Domain name resolution (I set it up in Alibaba cloud)

yum install mysql, start MySQL service, set MySQL account root password, and set power on auto start

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

rpm -ivh mysql-community-release-el7-5.noarch.rpm

yum install mysql-community-server -y

service mysqld restart

/usr/bin/mysqladmin -u root password '123.com'

chkconfig mysqld on

yum install Apache components, start, set power on and self start

yum install httpd -y

service httpd start

chkconfig httpd on

Install PHP, start the PHP-FPM process, view the port, and set it to start automatically after power on

yum install php php-fpm php-mysql -y

service php-fpm start

netstat -anput | grep php-fpm

chkconfig php-fpm on

Installing Discuz

wget http://download.comsenz.com/DiscuzX/3.2/Discuz_X3.2_SC_UTF8.zip

unzip Discuz_X3.2_SC_UTF8.zip

Configure Discuz (because PHP accesses / var/www/html / folder by default), authorize, restart Apache

cp -r upload/* /var/www/html/

chmod -R 777 /var/www/html
