Linux va Nginx kabi veb-serverlar bilan hamda pochta serverlari bilan qanday tajribangiz bor?

Men Linux oilaviy tizimlar bilan keng tajribaga egaman (Debian, Ubuntu, CentOS/RHEL), jumladan o'rnatish, sozlash, boshqarish va muammolarni hal qilish. Komanda satri va Bash skriptlar bilan ishonch bilan ishlayman.

Nginx veb-serverlar bilan ishladim:

• Virtual hostlar, SSL/TLS sertifikatlarini sozlash.
• Reverse proxy, yukni taqsimlash.
• Ishlashini optimallashtirish (kesh, siqish).
• PHP-FPM, FastCGI bilan integratsiya.

Nginx uchun virtual host konfiguratsiyasi misoli:

server {
    listen 80;
    listen [::]:80;
    server_name myapp.com www.myapp.com;

    location / {
        proxy_pass http://backend_app; // Backendga so'rovlarni proxylash
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    # Statik fayllar uchun sozlash
    # location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
    #    expires 30d;
    #    add_header Cache-Control "public, no-transform";
    # }

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }
}

Mail serverlar bilan, ayniqsa Postfix va Dovecot bilan ishlash tajribam bor:

• O'rnatish va asosiy sozlash.
• SPF, DKIM, DMARC konfiguratsiyasi orqali yetkazib berishni yaxshilash.
• Spam filtrlash (SpamAssassin bilan).
• Foydalanuvchilar va domenlarni boshqarish.
• Loglarni monitoring qilish va muammolarni diagnostika qilish.

Postfix uchun relaylarni cheklash misoli:

# postconf -n mynetworks
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.1.0/24 // Ruxsat etilgan tarmoqlar
