Install  Web Server :  Nginx

apt관리자를 이용하여 간단히 설치한다. 

sudo apt-get update

sudo apt-get install nginx

On Ubuntu 16.04, Nginx is configured to start running upon installation.

ufw 에 등록 (Optional)

firewall인 ufw가 동작하고 있다면, Nginx가 접속할수 있도록 설정해야한다. 

설치여부확인 

⇒  sudo ufw status
Status: inactive

설정

⇒  sudo ufw allow 'Nginx HTTP'
Rules updated
Rules updated (v6)

…

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

⇒  curl -4 icanhazip.com

…..

Install DBMS : MySQL

간단하게 

sudo apt-get install mysql-server

root 사용자 암호를 설정한다.

설정

간단한 security script를 실행한다. (설정의 보안을 보완해준다.)

sudo mysql_secure_installation

Step 3: Install PHP for Processing

Nginx 가 PHP requests 를  processing할수 있도록 php-fpm (“fastCGI process manager) 설치한다. 
또한 MySQL과 communication할수 있도록 관련 모듈도 설치한다. 

sudo apt-get install php-fpm php-mysql

기본적으로 7버전이 설치된다. 

Configure the PHP Processor

보안 설정 

⇒  sudo vi /etc/php/7.0/fpm/php.ini

cgi.fix_pathinfo=0

설정후 php restart

⇒  sudo systemctl restart php7.0-fpm

Configure Nginx to Use the PHP Processor

Now, we have all of the required components installed. The only configuration change we still need is to tell Nginx to use our PHP processor for dynamic content.

We do this on the server block level (server blocks are similar to Apache’s virtual hosts). Open the default Nginx server block configuration file by typing:

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

index.php추가
server_name 에 도메인이나 IP추가 

	index index.php index.html index.htm index.nginx-debian.html;

	server_name 서버도메인이나 아이피;

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }

설정후 확인

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

NginX reload

⇒  sudo systemctl reload nginx

Step 5: Create a PHP File to Test Configuration

NginX가 php를 잘 처리하는지 확인 

새파일을 만들고, phpinfo()가 잘 동작하는지 확인한다.

sudo vi /var/www/html/info.php

sudo rm /var/www/html/info.php

추가  phpAdmin설치

sudo apt-get install phpmyadmin

location /phpmyadmin {
    root /usr/share/;
    index index.php index.html index.htm;
    location ~ ^/phpmyadmin/(.+\.php)$ {
    	try_files $uri =404;
      fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
      include fastcgi_params;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		}
    location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
      root /usr/share/;
    }
  }

적용

sudo systemctl reload nginx
