Instal Apache2

Lihat Setting Up LAMP 

$ sudo apt-get install apache2 php libapache2-mod-php
$ sudo /usr/sbin/apachectl start
$ sudo chkconfig apache2ctl on
$ sudo sh -c 'echo "<?php phpinfo();?>" > /var/www/html/phpinfo.php'

Cek http://[IP_ADDRESS] dan http://[IP_ADDRESS]/phpinfo.php 

/etc/apache2/
|-- apache2.conf
|       `--  ports.conf
|-- mods-enabled
|       |-- *.load
|       `-- *.conf
|-- conf-enabled
|       `-- *.conf
|-- sites-enabled
|       `-- *.conf

Konfigurasi Apache2 Ubuntu

  • File konfigurasi utama adalah apache2.conf. Ini menempatkan potongan-potongan bersama dengan memasukkan semua file konfigurasi yang tersisa ketika memulai server web, * ports.conf selalu disertakan dari file konfigurasi utama. Ini digunakan untuk menentukan port mendengarkan untuk koneksi masuk, dan file ini dapat disesuaikan kapan saja.
  • File-file konfigurasi di direktori-direktori mod-enabled /, conf-enabled / dan enabled-enabled / berisi cuplikan-cuplikan konfigurasi tertentu yang masing-masing mengelola modul, fragmen konfigurasi global, atau konfigurasi host virtual. Mereka diaktifkan dengan menghubungkan file-file konfigurasi yang tersedia dari masing-masing * -tersedia / rekan. Ini harus dikelola dengan menggunakan a2enmod pembantu kami, a2dismod, a2ensite, a2dissite, dan a2enconf, a2disconf. Lihat halaman manual masing-masing untuk informasi terperinci.
  • Biner disebut apache2. Karena penggunaan variabel lingkungan, dalam konfigurasi default, apache2 perlu dimulai / dihentikan dengan /etc/init.d/apache2 atau apache2ctl. Memanggil / usr / bin / apache2 secara langsung tidak akan berfungsi dengan konfigurasi default.
  • Root Dokumen Secara default, Ubuntu tidak mengizinkan akses melalui browser web ke file apa pun selain dari yang terletak di / var / www, direktori public_html (bila diaktifkan) dan <code>/ usr / share (untuk aplikasi web). Jika situs Anda menggunakan root dokumen web yang terletak di tempat lain (seperti di / srv), Anda mungkin perlu memasukkan daftar putih direktori root dokumen Anda di /etc/apache2/apache2.conf.
  • Root dokumen default Ubuntu adalah / var / www / html. Anda dapat membuat host virtual sendiri di bawah <code>/ var / www. Ini berbeda dengan rilis sebelumnya yang memberikan keamanan yang lebih baik.
Dokumen Lengkap apache2-doc tersedia di: /usr/share/doc/apache2/README.Debian.gz

Instal Postgres

Lihat Setting up PostgreSQL 

$ sudo apt-get -y install postgresql postgresql-client postgresql-contrib
$ sudo -s
root@instance-sql:~# sudo -u postgres psql postgres 
postgres=# SELECT version();
                                                   version

(1 row)

Untuk ubah versi lihat Cek Port, Ubah Port atau Disable Versi 

$ pg_lsclusters
Ver Cluster Port Status Owner    Data directory               Log file
9.3 main    5432 online postgres /var/lib/postgresql/9.3/main /var/log/postgresql/postgresql-9.3-main.log
9.5 main    5433 online postgres /var/lib/postgresql/9.5/main /var/log/postgresql/postgresql-9.5-main.log
10  main    5434 online postgres /var/lib/postgresql/10/main  /var/log/postgresql/postgresql-10-main.log

$ sudo nano /etc/postgresql/9.3/main/start.conf 
#ubah 'auto' ke 'disabled'

$ sudo nano /etc/postgresql/10/main/start.conf 
#ubah 'auto' ke 'disabled'

Edit File pg_hba.conf dan postgresql.conf 

$ sudo nano /etc/postgresql/9.5/main/postgresql.conf 
#hapus tagar dan ubah 'localhost' ke '*' dan
#ubah '5433' ke '5432'

$ sudo nano /etc/postgresql/9.5/main/pg_hba.conf
#tambahkan di baris paling bawah
#host    all             all           0.0.0.0/0        trust

Restart postgres dan cek database 

$ sudo service postgresql restart
$ sudo -s

postgres=# SELECT version();
                                                      version

Issue

Setiap Anda update server atau component sebaiknya Anda cek startup atau booting nya

Error NXDOMAIN

Stop Instance, tunggu sampai berhenti, lalu start dan konek ke serial-port 

$ gcloud compute connect-to-serial-port <nama-instance> --zone=<nama-zone>
Cek error berikut 
instance systemd-resolved[882]: Server returned error NXDOMAIN, \
mitigating potential DNS violation DVE-2018-0001, \
retrying transaction with reduced feature level UDP.

Ini dikarenakan ada konfigurasi lama yang masih aktif.

Cara cari solusi: Googling: [SOLVED] Server returned error NXDOMAIN

Arternatif solusinya antara lain sbb

Dari alrenatif di atas salah satu langkah yang bisa dilakukan adalah sbb 
$  ls -l /etc/resolv.conf
lrwxrwxrwx 1 root root 29 Feb 9 /etc/resolv.conf -> ../run/resolvconf/resolv.conf

$ sudo nano /run/resolvconf/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

$ test -e /run/systemd/resolve/resolv.conf && echo file exists || echo file not found
file exists

$ sudo nano /run/systemd/resolve/resolv.conf
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients directly to

# replace this symlink by a static file or a different symlink.

$ sudo ln -fs /run/systemd/resolve/resolv.conf /etc/resolv.conf
$ ls -l /etc/resolv.conf
lrwxrwxrwx 1 root root 32 Mar 11 /etc/resolv.conf -> /run/systemd/resolve/resolv.conf
Stop instance dan cek kembali seperti langkah semula.
Jika ternyata masih ada Warning seperti ini 
Mar 11 04:02:57 instance resolvconf[341]: /etc/resolvconf/update.d/libc: 
Warning: /etc/resolv.conf is not a symbolic link to /run/resolvconf/resolv.conf
Maka lalukan peintah berikut.. 
$ sudo dpkg-reconfigure resolvconf
ls -l /etc/resolv.conf
