WordPress-Load-Balance-Layer-7

Repositori berisi langkah konfigurasi load balancing pada WordPress khususnya pada layer 7

Persiapan

• 1 Node Load Balance
  • server-ha.floss.my.id
• 2 Node Backend Webserver
  • backend1.floss.my.id
  • backend2.floss.my.id
• 1 Node Database
  • server-db.floss.my.id

Pre-installation

1. Buat bash script untuk otomasi install paket epel

$ vi epel.sh

#!/bin/bash
for i in server-ha.floss.my.id \
backend1.floss.my.id \
backend2.floss.my.id \
server-db.floss.my.id
do
   ssh root@"$i" yum install epel-release htop yum-utils -y
done

Beri permission execute pada file epel.sh :

$ chmod +x epel.sh

Eksekusi file tersebut :

$ ./epel.sh

2. Buat bash script untuk otomasi install paket nginx dan php

$ vi ephp.sh

#!/bin/bash
for i in backend1.floss.my.id \
backend2.floss.my.id
do
   ssh root@"$i" yum install nginx -y;
   ssh root@"$i" "systemctl enable nginx && systemctl start nginx";
   ssh root@"$i" yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm -y;
   ssh root@"$i" yum-config-manager --enable remi-php72;
   ssh root@"$i" yum -y install php \
               php-intl \
               php-common \
               php-opcache \
               php-mcrypt \
               php-cli \
               php-gd \
               php-curl \
               php-mysqlnd  \
               php-dom \
               php-curl \
               php-zip \
               php-mbstring \
               php-xml \
               php-xmlreader \
               php-simplexml \
               php-bcmath \
               php-soap \
               php-amqplib \
               php-fpm;
    ssh root@"$i" "systemctl enable php-fpm && systemctl start php-fpm";
done

Beri permission execute pada file epel.sh :

$ chmod +x ephp.sh

Eksekusi file tersebut :

$ ./ephp.sh

3. Install HAProxy pada node load balance

$ yum install haproxy -y

Jalankan service HAProxy

$ systemctl start haproxy

Aktifkas service HAProxy

$ systemctl enable haproxy

4. Install MariaDB pada node database

Tambahkan repository MariaDB :

$ vi /etc/yum.repos.d/mariadb.repo

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Install MariaDB

$ yum install -y mariadb-server

Jalankan service HAProxy

$ systemctl start mariadb

Aktifkas service HAProxy

$ systemctl enable mariadb

Konfigurasi

1. Pada node backend webserver :

Server Block yang digunakan adalah sebagai berikut :

server {
        root /var/www/html/wp;
        index index.php index.html index.htm;
        server_name frontend.floss.my.id;
        server_tokens off;
        access_log /var/log/nginx/frontend_access.log;
        error_log /var/log/nginx/frontend_error.log;
        gzip on;
        gzip_vary on;
        gzip_min_length 10240;
        gzip_proxied expired no-cache no-store private auth;
        gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/xml application/javascript text/x-javascript;
        gzip_disable "MSIE [1-6]\.";


        location / {
          try_files $uri $uri/ /index.php?$args;
          proxy_headers_hash_max_size 512;
          proxy_headers_hash_bucket_size 64;
          proxy_set_header Host $host;
          proxy_set_header X-Forwarded-Proto $scheme;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          add_header Front-End-Https on;
        }

    location ~*  \.(jpg|jpeg|png|gif|ico|css|js)$ {
        expires 365d;
    }

    location ~*  \.(pdf)$ {
        expires 30d;
    }
        location ~ \.php$ {
         fastcgi_pass 127.0.0.1:9000;
         fastcgi_index   index.php;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include fastcgi_params;
        }
