# Ubuntu Server LEMP 環境架設

1.下載 Ubuntu Live Server .iso 檔案：[點我下載](https://releases.ubuntu.com/22.04.4/ubuntu-22.04.4-live-server-amd64.iso)。
2.安裝 Ubuntu Live Server GUI 介面 `非必要，新手或不熟悉Linux者建議安裝`

#sudo apt install -y ubuntu-desktop

3.安裝 Nginx Web 伺服器，並設定開機自動啟用。

#sudo apt install nginx -y
#sudo systemctl enable nginx

4.修改 www 資料夾權限

#sudo chown -R www-data:www-data /var/www

5.下載並透過指令解壓縮安裝 VS Code ：[點我下載](https://code.visualstudio.com/)

#sudo dpkg -i 檔名.deb

6.安裝 MySQL：安裝資料庫系統，必且進行基本配置。

sudo apt install mysql-server -y
#-->> Pi的話使用 sudo apt install mariadb-server

#sudo mysql_secure_installation
#ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'new_password';

7.安裝 PHP：安裝 PHP 以及必要的 PHP 擴展。

sudo apt install php-fpm php-mysql php-imagick php-gd php-zip php-intl
sudo chmod -R 775 /var/www

8.安裝 phpMyAdmin後，配置 Nginx.conf（localhost 才可進入資料庫後台）

sudo apt-get install phpmyadmin

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
worker_connections 768;
}

http {
client_max_body_size 0; # Nginx 必加入，會影響可傳送資料的大小，0 表示無限制

sendfile on;
tcp_nopush on;
types_hash_max_size 2048;

include /etc/nginx/mime.types;
default_type application/octet-stream;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;

access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

gzip on;

##
# Virtual Host Configs
##

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

#localhost + phpmyadmin
server{
listen 80;
server_name localhost; #DomainName

root /var/www/html; # Website Folder
index index.php index.html index.htm index.nginx-debian.html;

location / {
try_files $uri $uri/ /index.php?$args;
}

location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

location /phpmyadmin {
allow 127.0.0.1; #限定本機才能進入確保安全
deny all;
alias /usr/share/phpmyadmin;
try_files $uri $uri/ =404;

location ~ ^/phpmyadmin/(.+\.php)$ {
try_files $uri = 404;
fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
}
}
}
}

9.將www資料夾權限暫時改為 777，將需要的網站檔案放入（如：WordPress）

#sudo chmod -R 777 /var/www
#sudo chown -R www-data:www-data /var/www

10.執行安裝步驟結束後，將 wp-config.php 加入以下程式碼，確保 https 讀取完整資源

#if (!empty($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] === 'https') {
$_SERVER['HTTPS'] = 'on';
}

11.依照需要調整 WordPress 的可存取記憶體

#define('WP_MEMORY_LIMIT', '256M');

12.安裝 Redis Server 加快網站存取速度

#sudo apt install redis-server
