+## 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`
+```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`
+
+```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-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
