    sudo apt-get update
   

3. Install mysql server

    sudo mysql -u root -p

Install MYSQL using yum command if apt-get command not found.

follow below docs.

https://dev.mysql.com/doc/mysql-repo-excerpt/5.6/en/linux-installation-yum-repo.html

Now Clone any node.js project in ec2 instance and install all the dependency but before that you need to install node and npm in your ec2 instance

In db.js file you should provide the valid details in mysql.createConnection() method

   const Bluebird=require('bluebird');
   const mysql=require('mysql');

   const connection= mysql.createConnection({
       host : 'localhost',
       user : 'root',           //by default user name
       password :'',            //put password that you have created while installing the mysql in ec2
       database : 'node'       // provide database name ,created in ec2
    });

   connection.connect((err)=>{
       if(err) throw err;
       console.log('MySQL Connected ...');
   });

   global.db=Bluebird.promisifyAll(connection);
   module.exports=db;

Now set custom port in ec2 instance in which your express server is running after selecting security group from the left navigation view.

You can see we have Custom TCP rule in port 3002. You can set any port in which you are running your express server.

Now run your project . If you have installed mysql successfully then server will run successfully.

If you get error

Client does not support authentication protocol requested by server; consider upgrading MySQL client

Then you need to change the root plugin in mysql

Run below command

 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'new_password';

You are good to go . Run your server.

http://18.191.201.10:3002/getPosts will return all the post in the database

here 18.191.201.10 is the IPv4 Public IP of EC2
