Mount harddisk

Using /dev/disk/by-uuid/:

  • Open a terminal.
  • Type blkid or ls -l /dev/disk/by-uuid/ and press Enter.
  • This will display a list of symlinks, where the filename is the UUID and the target is the device it points to (e.g., lrwxrwxrwx 1 root root 10 Jul 12 12:00 1234-5678 -> ../../sda1).
  • Identify the UUID you need and then use the corresponding device path (e.g., /dev/sda1) in other commands if needed.

Edit file /etc/fstab 

/dev/disk/by-uuid/50046676-d3fb-6183-54e4-7d65cd58e8ad /mount_name ext4 defaults 0 1

Then update new fstab with command ???

Check harddisk problem

Check with 

fsck /dev/sdax
Repair with 
fsck /dev/sdax -y

Create new user

Ubuntu create user account commands 
sudo adduser <username>

Make user to sudoer

sudo adduser <username> sudo

Make user ssh

Update OS 

sudo apt update
sudo apt upgrade

Check current services running 

sudo service --status-all

Step 1 – Installing the Nginx Web Server

sudo apt install nginx

Test nginx config 

sudo nginx -t

Restart nginx

sudo systemctl restart nginx
sudo systemctl reload nginx
sudo service nginx restart
sudo service nginx reload

Enable HTTP/2 in Nginx on Ubuntu

sudo nano /etc/nginx/sites-available/your_domain
listen 443 ssl http2;
listen [::]:443 ssl http2 ipv6only=on;

Step 2 – Installing MariaDB to Manage Site Data

sudo apt install mariadb-server
sudo mysql_secure_installation
    Switch to unix_socket authentication [Y/n] n
sudo mysql
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysqlnativepassword BY 'password';
mysql> FLUSH PRIVILEGES;

ปรับแต่ง config

nano /etc/mysql/mariadb.conf.d/50-server.cnf


[mysqld]
log_slow_query_file    = /var/log/mysql/mariadb-slow.log
log_slow_query_time    = 2
...
innodb_buffer_pool_size = 256M
innodb_log_file_size = 128M

ตรวจสอบตารางว่า crash หรือไม่

mariadb-check -u user -p -c database

Step 3 – Installing PHP and Configuring Nginx to Use the PHP Processor => รายละเอียด

ถ้าต้องการถอด php ออก ด้วย 

sudo apt-get purge php7.*
sudo apt purge php8.*
sudo apt-get autoclean
sudo apt-get autoremove

Install php 8.3

sudo add-apt-repository ppa:ondrej/php
sudo apt update && sudo apt-get install ca-certificates apt-transport-https software-properties-common
sudo apt install php8.3-fpm
php -v
php --modules
apt install -y php8.3-common php8.3-fpm php8.3-mysql php8.3-redis php8.3-mongodb php8.3-zip php8.3-gd php8.3-mbstring php8.3-cli php8.3-curl php8.3-xml php8.3-bcmath

Install php 8.5

sudo add-apt-repository ppa:ondrej/php
sudo apt update && sudo apt-get install ca-certificates apt-transport-https software-properties-common
sudo apt install php8.5-fpm
php -v
php --modules
apt install -y php8.5-common php8.5-fpm php8.5-mysql php8.5-zip php8.5-gd php8.5-mbstring php8.5-cli php8.5-curl php8.5-xml php8.5-bcmath

ปรับ config PHP

เปลี่ยนค่า session.gc_probability, date.timezone, postmaxsize, upload_max_filesize

nano /etc/php/8.3/fpm/php.ini

session.gc_probability = 1
date.timezone = Asia/Bangkok
post_max_size = 64M
upload_max_filesize = 64M

แก้ไขค่า php pool

nano /etc/php/8.3/fpm/pool.d/www.conf

pm.max_children = 30
pm.start_servers = 5
pm.min_spare_servers = 3
pm.max_spare_servers = 5

Enabling PHP8.3 on Nginx server 

sudo nano /etc/nginx/sites-available/default


index index.php index.html
...
location ~ \.php$ {
        include snippets/fastcgi-php.conf
        # With php-fpm (or other unix sockets):
        fastcgi_pass unix:/var/run/php/php8.3-fpm.sock;
        # With php-cgi (or other tcp sockets):
        <a class="hashtag" href="/tags/fastcgi">#fastcgi</a>_pass 127.0.0.1:9000;
}

Restart php 

sudo service php8.3-fpm restart

Restart nginx 

sudo systemctl restart nginx.service

Install phpmyadmin

apt install phpmyadmin
sudo ln -s /usr/share/phpmyadmin /var/www/your_domain/phpmyadmin

Create site config

cd /etc/nginx/sites-available
nano domain.conf
cd /etc/nginx/sites-enabled
ln -s ../sites-available/domain.conf domain.conf

Step 4 - How To Secure Nginx with Let's Encrypt on Ubuntu 22.04

sudo apt remove certbot
sudo snap install core; sudo snap refresh core
sudo snap install --classic certbot
sudo ln -s /snap/bin/certbot /usr/bin/certbot
sudo certbot

ติดตั้ง SSL Certificate Filde วิธีการติดตั้ง SSL Certificate บน Nginx Server

Step 5 – ขั้นตอนสุดทัาย - Check List

1. Create new user

config PHP

Change timezone to Asia/Bangkok 
sudo nano /etc/php/8.3/fpm/php.ini
Then change 
date.timezone = Asia/Bangkok
Then restart php 
sudo service php8.3-fpm restart
เปลี่ยนขนาดอัพโหลดไฟล์
It sets the maximum allowed size of the client request body, specified in the “Content-Length” request header field. Here’s an example of increasing the limit to 50MB in /etc/nginx/nginx.conf file. Set in http block which affects all server blocks (virtual hosts). 
nano /etc/nginx/nginx.conf
http {
    ...
    client_max_body_size 50M;
}
In each domain config in site-a Set in server block, which affects a particular site/app 
nano /etc/nginx/sites-available/domain.conf
server {
    ...
    client_max_body_size 50M;
}
Set in location block, which affects a particular directory (uploads) under a site/app. 
location /uploads {
    ...
    client_max_body_size 50M;
}<br />
Save the file and restart Nginx web server to apply the recent changes using following command. 
systemctl restart nginx

Old version

ถอนการติดตั้ง

หากมีการติดตั้ง apache2 ไว้ก่อน สามารถถอนการติดตั้งด้วย 

apt-get purge apache2
apt-get autoremove

กรณีการอัพเกรดจาก Apache มีขั้นตอนของการตรวจสอบ และ ถอดโปรแกรม
