Apache, MySQL, PHP (LAMP) Stack-ni Ubuntu-ga qanday o'rnatish kerak 20.04 / 20.10 Ushbu qo'llanmada biz Ubuntu Server 20.04 / 20.10 da LAMP Stack (Apache, MySQL, PHP) o'rnatamiz va veb-serverni sozlaymiz.
1. Apache O'rnatish
Ubuntu 20.04 / 20.10 da LAMP Stack-ning birinchi komponenti Apache. Paket ro'yxatlarini yangilash va Apache-ni o'rnatish bilan boshlang. Davom etish so'ralganda y va ENTER tugmalarini bosing.
sudo apt update && sudo apt install apache2
O'rnatish bir necha daqiqa davom etishi mumkin. O'rnatilgandan so'ng, Ubuntu 20.04 / 20.10 da xavfsizlik devorini sozlash uchun 2-bosqichga o'ting.
2. Configure Firewall
Ubuntu 20.04 / 20.10 da LAMP Stack-ga qo'shimcha xavfsizlik ta'minlaydigan xavfsizlik devorini sozlash tavsiya etiladi.
Biz SSH uchun xavfsizlik devori qoidasini qo'shishni boshlaymiz, chunki agar siz serveringizni masofadan sozlayotgan bo'lsangiz, xavfsizlik devorini yoqishda qulflanib qolishni xohlamaysiz. Siz buni Ubuntu 20.04 / 20.10 qo'llanmasiga Dastlabki server sozlamalarida qilgan bo'lishingiz mumkin, ammo ehtimol uni yana qo'shib qo'yish zarar qilmaydi. Agar qoida allaqachon mavjud bo'lsa, buyruq shunchaki uni o'tkazib yuboradi.
sudo ufw allow OpenSSH
Agar sizda "XATO: openSSH ga mos keladigan profil topilishi mumkin" degan xato bo'lsa, bu siz serverni masofadan sozlamaganligingizni va unga e'tibor bermasligingizni anglatishi mumkin.
Endi biz Apache uchun xavfsizlik devori qoidalarini qo'shishimiz mumkin.
sudo ufw allow in "Apache Full"
Agar u allaqachon bo'lmasa, xavfsizlik devorini yoqing.
sudo ufw enable
Agar "Buyruq mavjud ssh ulanishlarini buzishi mumkin" degan xabarni ko'rsangiz y tugmasini bosing.
Agar xavfsizlik devori to'g'ri yoqilgan bo'lsa, siz "Firewall is active and enabled on system startup - xavfsizlik devori tizimni ishga tushirishda faol va yoqilgan" ni ko'rishingiz kerak.
Siz shuningdek xavfsizlik devori holatini quyidagicha tekshirishingiz mumkin:
sudo ufw status
Status: active

To Action From

-- ------ ----
OpenSSH ALLOW Anywhere
Apache Full ALLOW Anywhere
OpenSSH (v6) ALLOW Anywhere (v6)
Apache Full (v6) ALLOW Anywhere (v6)
Yuqorida biz xavfsizlik devori faolligini ko'rayapmiz va har bir xizmat uchun ikkita qoidaga ega. v6 IPv6 uchun qisqa.
3. Test Apache
Apache Ubuntu 20.04 / 20.10 da to'g'ri o'rnatilganligini bilish uchun biz xizmatning amaldagi holatini tekshirib ko'rishimiz mumkin.
