Pengujian PHP melalui web
Sebelum melakukan pengujian silahkan buat file untuk menampilkan php version dan sesuaikan direktori website berada, setelah itu silahkan akses menggunakan browser http://namadomain.com/index.php
1 2 | [root@iaasweb ~]# touch /var/www/iaasweb.iaas.web.id/html/index.php [root@iaasweb ~]# echo "<?php phpinfo(); ?>" >> /var/www/iaasweb.iaas.web.id/html/index.php |
Instalasi MySQL
Download MySQL melalui repositori resminya, kemudian verifikasi paketnya menggunakan MD5 untuk memastikan bahwa isi file tersebut aman dan tidak rusak
1 2 3 4 5 6 7 | [root@iaasweb ~]# curl -sSLO https://dev.mysql.com/get/mysql80-community-release-el7-5.noarch.rpm [root@iaasweb ~]# md5sum mysql80-community-release-el7-5.noarch.rpm e2bd920ba15cd3d651c1547661c60c7c mysql80-community-release-el7-5.noarch.rpm [root@iaasweb ~]# rpm -ivh mysql80-community-release-el7-5.noarch.rpm [root@iaasweb ~]# yum -y install mysql-server [root@iaasweb ~]# mysql --version mysql Ver 8.0.31 for Linux on x86_64 (MySQL Community Server - GPL) |
Konfigurasi MySQL
Berikutnya adalah melakukan auto start atau persistent mode agar saat restart server maka MySQL daemon langsung aktif, mengamankan MySQL dan membuat password baru, namun sebenarnya terdapat temporary password (tidak direkomendasikan digunakan)

Estimated strength of the password: 100 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y Success. All done! |
Instalasi phpMyAdmin
Sebelum melakukan instalasi harap pastikan sudah melakukan instalasi web server, php, mysql, dan juga repository epel-release
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | [root@iaasweb ~]# yum -y --enablerepo=remi install phpmyadmin [root@iaasweb ~]# nano /etc/httpd/conf.d/phpMyAdmin.conf # phpMyAdmin - Web based MySQL browser written in php # # Allows only localhost by default # # But allowing phpMyAdmin to anyone other than localhost should be considered # dangerous unless properly secured by SSL Alias /phpMyAdmin /usr/share/phpMyAdmin Alias /phpmyadmin /usr/share/phpMyAdmin <Directory /usr/share/phpMyAdmin/> AddDefaultCharset UTF-8 Require local Require ip 10.177.10.0/27 </Directory> <Directory /usr/share/phpMyAdmin/setup/> Require local </Directory> |
Pada konfigurasi phpMyAdmin ada beberapa hal yang perlu diperhatikan diantaranya adalah:
1 2 3 4 5 6 7 | Require ip your_workstation_IP_address . . . Allow from your_workstation_IP_address . . . Require ip your_workstation_IP_address . . . Allow from your_workstation_IP_address |
Pada baris-baris diatas perlu disesuaikan dengan IP yang digunakan saat ini, setelah disesuikan restart webserver dan akses melalui browser http://namadomain.com/phpmyadmin dan masukkan username root dan password yang sudah dibuat sebelumnya
