Tutorial kali ini membahas tentang bagaimana cara install WordPress dengan Nginx web server dipasangkan dengan PHP v7.4 dan MariaDB database atau lebih populer disingkat menjadi LEMP (Linux Nginx MySQL/MariaDB PHP).

0.Update System

Update CentOS dan install EPEL repository.

yum update -y	
yum install epel-release -y

1 2	yum update -y yum install epel-release -y

1.Install Nginx

Install Nginx.

yum install nginx -y

1	yum install nginx -y

Aktifkan dan jalankan Nginx service.

systemctl enable nginx

systemctl status nginx

systemctl enable nginx

systemctl start nginx

systemctl status nginx

2.Install PHP 7.4

Install yum-utils dan REMI repository.

yum install yum-utils -y
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm -y

1 2	yum install yum-utils -y yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm -y

Verifikasi hasil install REMI repository, lihat isi direktori yum.repos.d.

ls -l /etc/yum.repos.d

1	ls -l /etc/yum.repos.d

Aktifkan REMI PHP7.4 repository.

yum-config-manager --enable remi-php74

1	yum-config-manager --enable remi-php74

Install PHP 7.4 beserta extension yang dibutuhkan.

yum install php74-php php74-php-fpm php74-php-gd php74-php-json php74-php-mbstring php74-php-mysqlnd php74-php-xml php74-php-xmlrpc php74-php-opcache -y

1	yum install php74-php php74-php-fpm php74-php-gd php74-php-json php74-php-mbstring php74-php-mysqlnd php74-php-xml php74-php-xmlrpc php74-php-opcache -y

Buat symbolic link php ke php74 dan cek PHP yang telah terinstall.

ln -s /usr/bin/php74 /usr/bin/php
php -v

1 2	ln -s /usr/bin/php74 /usr/bin/php php -v

Konfigurasi PHP-FPM.

vi /etc/opt/remi/php74/php-fpm.d/www.conf

1	vi /etc/opt/remi/php74/php-fpm.d/www.conf

Ubah opsi seperti di bawah ini.

...
user = nginx
...
group = nginx
...
listen = /run/php74-fpm.sock
...
listen.owner = nginx
listen.group = nginx
listen.mode = 0660

...

user = nginx

...

group = nginx

...

listen = /run/php74-fpm.sock

...

listen.owner = nginx

listen.group = nginx

listen.mode = 0660

Jalankan PHP-FPM service.

systemctl enable php74-php-fpm	
systemctl start php74-php-fpm	
systemctl status php74-php-fpm

systemctl enable php74-php-fpm

systemctl start php74-php-fpm

systemctl status php74-php-fpm

3.Membuat Nginx Server Block

Membuat file konfigurasi server block, ganti DOMAIN.COM dengan nama domain yang anda gunakan.

vi /etc/nginx/conf.d/DOMAIN.COM.conf

1	vi /etc/nginx/conf.d/DOMAIN.COM.conf

Script konfigurasi server block.

server {
    listen 80;
    server_name DOMAIN.COM www.DOMAIN.COM;
    root /var/www/DOMAIN.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:/run/php74-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/DOMAIN.COM.access.log;
    error_log /var/log/nginx/DOMAIN.COM.error.log;
}

server {

listen 80;

server_name DOMAIN.COM www.DOMAIN.COM;

root /var/www/DOMAIN.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:/run/php74-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/DOMAIN.COM.access.log;

error_log /var/log/nginx/DOMAIN.COM.error.log;

}

Membuat root directory dan file info.php.

mkdir /var/www/DOMAIN.COM
echo "<?php phpinfo(); ?>" > /var/www/DOMAIN.COM/info.php

1 2	mkdir /var/www/DOMAIN.COM echo "<?php phpinfo(); ?>" > /var/www/DOMAIN.COM/info.php

Uji konfigurasi dan restart Nginx service.

nginx -t
systemctl restart nginx
systemctl status nginx

nginx -t

systemctl restart nginx

systemctl status nginx

Uji apakah Nginx sudah bisa menjalankan script PHP dengan mengakses info.php.

Browse http://DOMAIN.COM/info.php.

4.Install MariaDB

Membuat file MariaDB repository versi 10.4.

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

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

Script mariadb.repo.

# MariaDB 10.4 CentOS repository list - created 2020-06-22 11:29 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

# MariaDB 10.4 CentOS repository list - created 2020-06-22 11:29 UTC

[mariadb]

name = MariaDB

baseurl = http://yum.mariadb.org/10.4/centos7-amd64

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

gpgcheck=1

Install MariaDB.
