Shunga ko'ra : β taqsimlangan nosozliklarga chidamli ob'ektni saqlash , Amazon S3 API va REST-API dan foydalanadigan mijozlar bilan mos keladi, shuningdek NFS server rejimini qo'llab-quvvatlaydi. Kichik va juda katta ob'ektlarni saqlash uchun optimallashtirish mavjud, o'rnatilgan keshlash mexanizmi mavjud va ma'lumotlar markazlari o'rtasida saqlashni takrorlash mumkin. Loyihaning maqsadlariga dublikatlarni ortiqcha takrorlash va bitta nosozlik nuqtasini bartaraf etish orqali 99.9999999% ishonchlilikka erishish kiradi. Loyiha kodi Erlang tilida yozilgan.
LeoFS uchta komponentdan iborat:
- β ob'ektlar va metama'lumotlarni qo'shish, olish va o'chirish operatsiyalariga xizmat qiladi, replikatsiya, tiklash va mijoz so'rovlarini navbatga qo'yish uchun javobgardir.
- β REST-API yoki S3-API yordamida HTTP so'rovlariga xizmat qiladi va javoblarni mijozlarga yo'naltiradi, xotira va diskdagi eng mashhur ma'lumotlarni keshlashni ta'minlaydi.
- β LeoFS Gateway va LeoFS Storage tugunlarining ishlashini nazorat qiladi, tugunlar holatini nazorat qiladi va nazorat summalarini tekshiradi. Ma'lumotlarning yaxlitligi va yuqori saqlash mavjudligini kafolatlaydi.
Ushbu postda biz Leofs-ni ansible-playbook va test S3, NFS yordamida o'rnatamiz.
Agar siz rasmiy o'yin kitoblari yordamida LeoFS-ni o'rnatishga harakat qilsangiz, turli xil xatolarga duch kelasiz: ,. Ushbu postda men bunday xatolarga yo'l qo'ymaslik uchun nima qilish kerakligini yozaman.
Ansible-playbook-ni ishga tushiradigan joyda siz netcat-ni o'rnatishingiz kerak.

When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [No]:
On some networks all internet access must go through a HTTP proxy.
