🛠️ 구현 방법

1. 디렉토리 구조 설정

/var/www/
├── mytalent.com/          # 메인 웹사이트
│   └── public_html/
├── api.mytalent.com/      # API 서버
│   └── public_html/
├── blog.mytalent.com/     # 블로그
│   └── public_html/
├── admin.mytalent.com/    # 관리자 패널
│   └── public_html/
└── static.mytalent.com/   # 정적 파일 서버
    └── public_html/

2. 가상 호스트 설정 파일

각 서비스에 대한 가상 호스트 설정 파일을 만들어보자:

메인 웹사이트 (www.mytalent.com.conf):

<VirtualHost *:443>
    ServerAdmin webmaster@mytalent.com
    ServerName mytalent.com
    ServerAlias www.mytalent.com
    DocumentRoot /var/www/mytalent.com/public_html
    
    # SSL 설정
    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/mytalent.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/mytalent.com/privkey.pem
    
    # 로그 설정
    ErrorLog ${APACHE_LOG_DIR}/mytalent.com_error.log
    CustomLog ${APACHE_LOG_DIR}/mytalent.com_access.log combined
    
    # 디렉토리 설정
    <Directory /var/www/mytalent.com/public_html>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    
    # 보안 헤더
    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
    Header always set X-Frame-Options SAMEORIGIN
    Header always set X-Content-Type-Options nosniff
</VirtualHost>

<VirtualHost *:80>
    ServerName mytalent.com
    ServerAlias www.mytalent.com
    Redirect permanent / https://www.mytalent.com/
</VirtualHost>

API 서버 (api.mytalent.com.conf):

<VirtualHost *:443>
    ServerAdmin webmaster@mytalent.com
    ServerName api.mytalent.com
    DocumentRoot /var/www/api.mytalent.com/public_html

    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/api.mytalent.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/api.mytalent.com/privkey.pem
    
    # 로그 설정
    ErrorLog ${APACHE_LOG_DIR}/api.mytalent.com_error.log
    CustomLog ${APACHE_LOG_DIR}/api.mytalent.com_access.log combined
    
    # API 서버 특수 설정
    <Directory /var/www/api.mytalent.com/public_html>
        Options -Indexes +FollowSymLinks
        AllowOverride All
        Require all granted
        
        # CORS 설정
        Header set Access-Control-Allow-Origin "https://www.mytalent.com"
        Header set Access-Control-Allow-Methods "GET, POST, OPTIONS, PUT, DELETE"
        Header set Access-Control-Allow-Headers "Content-Type, Authorization"
    </Directory>
</VirtualHost>

<VirtualHost *:80>
    ServerName api.mytalent.com
    Redirect permanent / https://api.mytalent.com/
</VirtualHost>

정적 파일 서버 (static.mytalent.com.conf):

<VirtualHost *:443>
    ServerAdmin webmaster@mytalent.com
    ServerName static.mytalent.com
    DocumentRoot /var/www/static.mytalent.com/public_html

    SSLCertificateKeyFile /etc/letsencrypt/live/static.mytalent.com/privkey.pem
    
    # 로그 설정
    ErrorLog ${APACHE_LOG_DIR}/static.mytalent.com_error.log
    CustomLog ${APACHE_LOG_DIR}/static.mytalent.com_access.log combined
    
    # 정적 파일 서버 최적화 설정
    <Directory /var/www/static.mytalent.com/public_html>
        Options -Indexes +FollowSymLinks
        AllowOverride None
        Require all granted
        
        # 캐싱 설정
        <IfModule mod_expires.c>
            ExpiresActive On
            ExpiresByType image/jpg "access plus 1 year"
            ExpiresByType image/jpeg "access plus 1 year"
            ExpiresByType image/gif "access plus 1 year"
