우분투 nginx에 PHP 설치하기

1. 시스템 업데이트

$ sudo apt update
$ sudo apt upgrade -y

 

 

2. 필수 패키지 설치

$ sudo apt install software-properties-common -y

 

 

3. 최신 PHP 버전을 제공하는 PPA 추가

$ sudo add-apt-repository ppa:ondrej/php -y
$ sudo apt update

 

 

4. PHP 최신 버전 설치 (현재 8.3)

$ sudo apt install php8.3 php8.3-fpm php8.3-cli php8.3-common php8.3-mysql php8.3-curl php8.3-xml php8.3-mbstring -y

 

 

5. 설치 확인

$ php -v
PHP 8.3.20 (cli) (built: Apr 10 2025 21:33:50) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.3.20, Copyright (c) Zend Technologies
    with Zend OPcache v8.3.20, Copyright (c), by Zend Technologies

 

 

6. nginx 와 연동

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

 

FastCGI 부분을 찾아 # 주석부분을 삭제하거나 아래와 같이 작성한다.

(index.php 추가)

# Add index.php to the list if you are using PHP
        index index.php index.html index.htm index.nginx-debian.html;

(생략)

# pass PHP scripts to FastCGI server
        #
        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
        #
        #       # With php-fpm (or other unix sockets):
                fastcgi_pass unix:/run/php/php8.3-fpm.sock;
        #       # With php-cgi (or other tcp sockets):
        #       fastcgi_pass 127.0.0.1:9000;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        location ~ /\.ht {
                deny all;
        }

 

 

문법이 맞는지 확인 후 nginx 재시작

 

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

 

$ sudo systemctl restart nginx

 

 

7. 선택사항 (PHP  설정 수정)
