Install Nextcloud 18 Debian 10 PHP MARIADB NGINX dan Letsencrypt

Last Updated on By Leave a Comment

Tutorial kali ini adalah cara untuk menginstall Nextcloud di Debian 10 lengkap dengan PHP 7.3 MariaDB 10.3 dan Nginx 1.16.1, buat yang belum tau Nextcloud, Nextcloud adalah aplikasi berbasis web yang memudahkan untuk berbagi file bisa dibilang mirip dengan Google Drive, dengan kemudahan untuk mengatur akses per folder/group. Nextcloud banyak digunakan oleh perusahaan untuk mempermudah akses berbagi file.

Setting DNS
Arahkan A record DNS ke cloud.jaranguda.com
contoh

cloud.jaranguda.com IN A 100.101.102.103

ganti 100.101.102.103 dengan IP public server anda.
setting DNS ini sangat penting karena akan digunakan untuk mengaktifkan SSL.

Install Pertama

Pertama install beberapa paket untuk memperlancar instalasi tahap-tahap selanjutnya.

apt-get install curl gnupg2 ca-certificates socat unzip lsb-release -y

Install PHP

apt-get install php7.3 php7.3-cli php7.3-common php7.3-gd php7.3-xmlrpc php7.3-fpm \
        php7.3-curl php7.3-intl php-imagick php7.3-mysql php7.3-zip php7.3-xml \
        php7.3-mbstring php7.3-bcmath -y

Tweak PHP

Update timezone, tambah maksimum upload jadi 100 MB, tambah limit memory php jadi 512MB.

sed -i 's/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/g' /etc/php/7.3/fpm/php.ini
sed -i 's/;date.timezone =/date.timezone = Asia\/Jakarta/g' /etc/php/7.3/fpm/php.ini
sed -i 's/post_max_size \=\ 8M/post_max_size \=\ 100M/g' /etc/php/7.3/fpm/php.ini
sed -i 's/upload_max_filesize \=\ 2M/upload_max_filesize \=\ 80M/g' /etc/php/7.3/fpm/php.ini
sed -i 's/memory_limit \=\ 128M/memory_limit \=\ 512M/g' /etc/php/7.3/fpm/php.ini

Install MariaDB

Install MariaDB 10.3 langsung dari repository Debian 10.

apt install mariadb-server -y

Buat User dan Database Nextcloud

Jalankan command mysql di terminal, lalu buat database dan user Nextcloud dengan copy paste dibawah ini

CREATE DATABASE nextcloud;
GRANT ALL PRIVILEGES ON nextcloud.* TO "nextcloud"@"localhost" IDENTIFIED BY "Kank4dcFKiXY9tjzgNmy";

Dari baris diatas nama database nextcloud, user nextcloud, password Kank4dcFKiXY9tjzgNmy. Ini bakalan kita gunakan sewaktu menginstall Nextcloud nanti.

Install Letsencrypt SSL

Untuk menginstall letsencrypt SSL kita akan menggunakan acme.sh. Terlebih dahulu install acme.sh dengan cara

mkdir ~/src
cd ~/src
wget https://github.com/acmesh-official/acme.sh/archive/2.8.5.tar.gz
tar zxvf 2.8.5.tar.gz
cd ~/src/acme.sh-2.8.5
bash acme.sh install
source ~/.bashrc

Generate SSL untuk domain cloud.jaranguda.com

acme.sh --issue -d cloud.jaranguda --standalone

disini kita tidak butuh webserver, dengan menjalankan perintah diatas kita akan menggunakan server bawaan acme.sh. acme.sh akan menggunakan port 80, pastikan port tersebut tidak digunakan agar proses generate SSL ini berhasil.
Setelah beberapa saat muncul pemberitahuan ssl berhasil dibuat

-----END CERTIFICATE-----
[Sat 21 Mar 2020 09:35:07 AM UTC] Your cert is in  /root/.acme.sh/cloud.jaranguda.com/cloud.jaranguda.com.cer 
[Sat 21 Mar 2020 09:35:07 AM UTC] Your cert key is in  /root/.acme.sh/cloud.jaranguda.com/cloud.jaranguda.com.key 
[Sat 21 Mar 2020 09:35:07 AM UTC] The intermediate CA cert is in  /root/.acme.sh/cloud.jaranguda.com/ca.cer 
[Sat 21 Mar 2020 09:35:07 AM UTC] And the full chain certs is there:  /root/.acme.sh/cloud.jaranguda.com/fullchain.cer

Cara ini hanya perlu sekali dijalankan, karena untuk renew (perpanjang) SSL, acme.sh sudah menginstall crontab, bisa dilihat dengan crontab -l

# crontab -l
41 0 * * * "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null

Install NGINX

Khusus untuk nginx ini kita akan menggunakan nginx versi terbaru dari repository NGINX langsung, karena versi terbaru membawa beberapa perubahan penting seperti rate_limit
Jalankan perintah berikut ini dari command line (CLI)

wget -qO - http://nginx.org/keys/nginx_signing.key | apt-key add -
echo "deb http://nginx.org/packages/debian/ $(lsb_release -sc) nginx" >> /etc/apt/sources.list
apt update
apt install nginx -y

Tweak NGINX

Kita akan melakukan sedikit tweak di nginx, untuk menyesuaikan max upload dari PHP dan beberapa konfigurasi lainnya.

cat >/etc/nginx/nginx.conf <<'EOL'

}

Buat folder untuk server block (vhost) nginx

mkdir -p /etc/nginx/sites/

Buat server block baru dengan nama cloud.jaranguda.com.conf. Ingat untuk mengganti cloud.jaranguda.com dengan nama domain anda.
