Install Nginx dan PHP-FPM di Node

Install Nginx di Node1 dan Node2.

sudo apt install nginx php php-fpm -y
sudo systemctl status nginx
sudo systemctl status php7.2-fpm

Membuat file index.php di Node1.

sudp mkdir /var/www/defnex.com
sudo echo "<h1>node1</h1>" > /var/www/defnex.com/index.php	

Membuat file index.php di Node2.

sudp mkdir /var/www/defnex.com
sudo echo "<h1>node2</h1>" > /var/www/defnex.com/index.php	

Membuat server block di Node1 dan Node2.

sudo nano /etc/nginx/conf.d/domainmu.com.conf

File konfigurasi server block.

server {
    listen 80;

    server_name domainmu.com www.domainmu.com;
    root /var/www/domainmu.com/;

    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        try_files $fastcgi_script_name =404;
        include fastcgi_params;
        fastcgi_pass                    unix:/var/run/php/php7.2-fpm.sock;
        fastcgi_index                   index.php;
        fastcgi_param DOCUMENT_ROOT     $realpath_root;
        fastcgi_param SCRIPT_FILENAME   $realpath_root$fastcgi_script_name;
    }

    access_log /var/log/nginx/domainmu.com.access.log;
    error_log /var/log/nginx/domainmu.com.error.log warn;
}

Uji dan restart Nginx.

sudo nginx -t
sudo systemctl restart nginx	
sudo systemctl status nginx	

Install dan Konfigurasi Nginx di Load Balancer

Install Nginx.

sudo apt install nginx -y
sudo systemctl status nginx	

Membuat server block untuk load balancing domain domainmu.com.

sudo nano /etc/nginx/conf.d/lb-domainmu.com.conf		

File konfigurasi server block load balancing domain domainmu.com.

upstream backend {
    server 10.130.127.167; #node1
    server 10.130.128.35;  #node2
}

server {
    listen 80;
    server_name defnex.com www.defnex.com;

    location / {
        proxy_redirect      off;
        proxy_set_header    X-Real-IP $remote_addr;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header    Host $http_host;
        proxy_pass http://backend;
    }
}	

Pada konfigurasi upstream backend dituliskan IP address dari backend server. Secara default metode load balancing yang digunakan adalah Round Robin. 

Konfigurasi load balancing jika menggunakan metode Least Connections.

upstream backend {
	least_conn;
    server 10.130.127.167; #node1
    server 10.130.128.35;  #node2
}	

Konfigurasi load balancing jika menggunakan metode IP Hash.

upstream backend {
	ip_hash;
    server 10.130.127.167; #node1
    server 10.130.128.35;  #node2
}	

Uji dan restart Nginx.

sudo nginx -t
sudo systemctl restart nginx	
sudo systemctl status nginx
