Linux Konteynerleri (LXC), sanalla\u015ft\u0131rma d\u00fcnyas\u0131nda hafif ve verimli bir alternatif sunar. Geleneksel sanal makinelerin aksine, LXC, ana sistemin \u00e7ekirde\u011fini payla\u015farak i\u015fletim sistemi d\u00fczeyinde izolasyon sa\u011flar. Bu sayede, daha az kaynak t\u00fcketimiyle birden fazla izole ortam \u00e7al\u0131\u015ft\u0131rabilir, geli\u015ftirme, test veya \u00e7e\u015fitli servislerin da\u011f\u0131t\u0131m\u0131n\u0131 kolayla\u015ft\u0131rabilirsiniz.<\/p>\n
Bu rehberde, Ubuntu 13.04 \u00e7al\u0131\u015ft\u0131ran bir VPS (Sanal \u00d6zel Sunucu) \u00fczerinde LXC’ye nas\u0131l ba\u015flayaca\u011f\u0131n\u0131z\u0131 ad\u0131m ad\u0131m \u00f6\u011freneceksiniz. Ubuntu 13.04 eski bir s\u00fcr\u00fcm olsa da, LXC’nin temel prensipleri ve kurulum ad\u0131mlar\u0131 bu s\u00fcr\u00fcmde de ge\u00e7erlidir ve mevcut altyap\u0131n\u0131z\u0131 verimli bir \u015fekilde kullanman\u0131z\u0131 sa\u011flayabilir.<\/p>\n
LXC (Linux Containers), Linux \u00e7ekirde\u011finin cgroups (control groups) ve namespace \u00f6zelliklerini kullanarak birden fazla izole Linux ortam\u0131n\u0131 ayn\u0131 ana sistem \u00fczerinde \u00e7al\u0131\u015ft\u0131rman\u0131za olanak tan\u0131yan bir i\u015fletim sistemi d\u00fczeyinde sanalla\u015ft\u0131rma teknolojisidir. Geleneksel sanal makineler (KVM, VirtualBox gibi) her sanal makine i\u00e7in ayr\u0131 bir \u00e7ekirdek ve i\u015fletim sistemi imaj\u0131 gerektirirken, LXC konteynerleri ana sistemin \u00e7ekirde\u011fini payla\u015f\u0131r. Bu, \u00f6nemli avantajlar sa\u011flar:<\/p>\n
Bir VPS \u00fczerinde LXC kullanmak, tek bir sunucuda birden fazla web sitesi, veritaban\u0131 sunucusu, geli\u015ftirme ortam\u0131 veya test ortam\u0131 gibi farkl\u0131 servisleri g\u00fcvenli ve izole bir \u015fekilde \u00e7al\u0131\u015ft\u0131rman\u0131n maliyet etkin bir yoludur.<\/p>\n
Ubuntu 13.04 VPS’inizde LXC’yi kurmak ve temel yap\u0131land\u0131rmalar\u0131 yapmak olduk\u00e7a basittir. \u0130lk olarak sunucunuzu g\u00fcncelleyerek ba\u015flayal\u0131m.<\/p>\n

Konteynerlerimin kaynaklar\u0131n\u0131 (CPU, RAM) nas\u0131l s\u0131n\u0131rlar\u0131m?<\/h3>\n
LXC, Linux \u00e7ekirde\u011finin cgroups (control groups) \u00f6zelli\u011fini kullanarak konteynerlerin CPU, RAM ve disk G\/\u00c7 gibi kaynaklar\u0131n\u0131 s\u0131n\u0131rlaman\u0131za olanak tan\u0131r.

Ubuntu 13.04 eski bir s\u00fcr\u00fcm, LXC kullanmak g\u00fcvenli mi?<\/h3>\n
Ubuntu 13.04 (Saucy Salamander) resmi olarak ya\u015fam d\u00f6ng\u00fcs\u00fcn\u00fcn sonuna ula\u015fm\u0131\u015ft\u0131r ve art\u0131k g\u00fcvenlik g\u00fcncellemeleri almamaktad\u0131r. Bu, \u00f6zellikle internete a\u00e7\u0131k bir VPS i\u00e7in \u00f6nemli bir g\u00fcvenlik riski olu\u015fturur. \u00dcretim ortamlar\u0131nda kullanman\u0131z \u00f6nerilmez. Bu rehber, belirli bir eski s\u00fcr\u00fcmde LXC’yi nas\u0131l kuraca\u011f\u0131n\u0131z\u0131 g\u00f6stermek i\u00e7in haz\u0131rlanm\u0131\u015ft\u0131r. M\u00fcmk\u00fcnse, daha g\u00fcncel ve desteklenen bir Ubuntu LTS s\u00fcr\u00fcm\u00fcne (\u00f6rne\u011fin 18.04, 20.04 veya 22.04) y\u00fckseltme yapman\u0131z \u015fiddetle tavsiye edilir. G\u00fcncel s\u00fcr\u00fcmlerde LXC’nin daha yeni \u00f6zellikleri ve daha iyi g\u00fcvenlik entegrasyonlar\u0131 bulunmaktad\u0131r.<\/p>\n
