Tulisan kali ini merupakan lanjutan dari artikel ini

Artikel sebelumnya melakukan instalasi letsencrypt dengan cara manual dari source. Memang sih kita dapat versi letsencrypt yang paling baru, tapi yaitu ribetnya ituloh... he..he..he..

Ok kali ini via port saja yang lebih simple,

sudo apt install certbot python3-certbot-apache
sudo vi /etc/apache2/sites-available/your_domain.conf

...
ServerName your_domain
ServerAlias www.your_domain
...

sudo apache2ctl configtest
sudo systemctl reload apache2

sudo ufw status
sudo ufw enable

sudo certbot --apache
sudo systemctl status certbot.timer

Dah gitu doang... he..he..he...

Karena versi free jadi banyak kekurangan, tapi kalau mau serius dengan full enkripsi dan fitur ssl bisa beli sertifikat ssl.

Sekedar pengingat saja, jadi maaf kalau berantakan.. :D

# INSTALL APACHE

sudo apt install apache2
sudo ufw app list
sudo ufw app info "Apache Full"
sudo ufw allow in "Apache Full"
test : http://your_server_ip

cek ip address : 
ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'


# INSTALL MYSQL

sudo apt install mysql-server
sudo mysql_secure_installation
sudo mysql
SELECT user,authentication_string,plugin,host FROM mysql.user;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

sudo vi /etc/mysql/my.cnf

[mysqld]
validate_password.policy=LOW

#Jika pusing hapus aja policy nya :
#1. Login to the mysql server as root mysql -h localhost -u root -p
#2. Run the following sql command: uninstall plugin validate_password;
#3. If last line doesn't work (new mysql release), you should execute UNINSTALL COMPONENT 'file://component_validate_password';

FLUSH PRIVILEGES;

Cek ulang :
SELECT user,authentication_string,plugin,host FROM mysql.user;

Untuk melakukan setting ip di Ubuntu dilakukan dengan langkah langkah sebagai berikut :

1. Edit netplan

sudo vi /etc/netplan/00-installer-config.yaml

2. Sesuaikan konfigurasi yang akan dipakai

# Untuk setting dhcp
#network:
#    ethernets:
#        eth0:
#            dhcp4: true
#            optional: true
#    version: 2


# untuk setting wifi
#ethernets:
#  id0:
#    [...]
#    access-points:
#      mode: infrastructure
#      bssid: mywifi
#      band: 5GHz
#      channel: 5
#    auth:
#      key-management: none | psk | eap
#      password: my-password-string


# untuk set static ip
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
      - 192.168.0.2/24
      gateway4: 192.168.0.1
      nameservers:
        addresses:
        - 208.67.222.222
        - 8.8.8.8

3. Terapkan konfigurasi yang sudah di sesuaikan.

sudo netplan apply
