Here's all you have to do to add clustering to your node.js application.

• save this code as cluster.js, and run cluster.js instead of server.js (or /bin/www, or whatever it's called for your project)
• the only line you'll need to change is the last line - it needs to point to the location of your server.js file

var cluster = require('cluster');

if (cluster.isMaster) {
  // Count the machine's CPUs
 var cpuCount = require('os').cpus().length;

# For each database:
ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
# For each table:
ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
# For each column:
ALTER TABLE table_name CHANGE column_name column_name VARCHAR(191) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
# (Don’t blindly copy-paste this! The exact statement depends on the column type, maximum length, and other properties. The above line is just an example for a `VARCHAR` column.)

Step 1 – Add new repository sources
At the time of writing, PHP 7.0 hasn’t yet made the official repository sources, so we need to add one which provides us with the PHP 7.0 packages. Edit your sources file with this command:

sudo nano /etc/apt/sources.list

Below the existing entries in the file on a blank line, add the following two lines:

deb http://repozytorium.mati75.eu/raspbian jessie-backports main contrib non-free
#deb-src http://repozytorium.mati75.eu/raspbian jessie-backports main contrib non-free
Your file should look a little like this:

sudo mkdir /var/run/mysqld
sudo chmod 777 /var/run/mysqld
sudo /etc/init.d/mysql stop
sudo mysqld_safe --skip-grant-tables &
mysql -uroot

use mysql;
update user set authentication_string=password('mynewpassword') where user='root';
flush privileges;
quit
