S\u0103pt\u0103m\u00e2na trecut\u0103, \u00een prima parte<\/a><\/noindex> aceast\u0103 articol, am descris cum este construit\u0103 combina\u021bia Apache \u0219i Nginx \u00een Timeweb. Suntem foarte recunosc\u0103tori cititorilor pentru \u00eentreb\u0103rile \u0219i discu\u021biile active! Ast\u0103zi v\u0103 povestim cum este implementat\u0103 disponibilitatea mai multor versiuni PHP pe un singur server \u0219i de ce garant\u0103m siguran\u021ba datelor clien\u021bilor no\u0219tri.<\/p>\n

\"Apache
\nG\u0103zduire virtual\u0103<\/b> (Shared-hosing) presupune c\u0103 pe un singur server sunt g\u0103zduite numeroase conturi de clien\u021bi. Pe contul unui client, \u00een general, exist\u0103 mai multe site-uri. Site-urile func\u021bioneaz\u0103 at\u00e2t pe CMS-uri Standard (de exemplu, Bitrix), c\u00e2t \u0219i pe platforme personalizate. Astfel, cerin\u021bele tehnice ale tuturor sistemelor sunt diferite, motiv pentru care pe un singur server trebuie s\u0103 gestion\u0103m mai multe versiuni PHP.
\n<\/a><\/noindex>
\nCa server web principal, utiliz\u0103m Nginx: acesta accept\u0103 toate conexiunile externe \u0219i serve\u0219te con\u021binut static. Celelalte cereri sunt proxificate mai departe, c\u0103tre serverul web Apache. Aici \u00eencepe magia: pentru fiecare versiune PHP este pornit o instan\u021b\u0103 separat\u0103 Apache, care ascult\u0103 un port specific. Acest port este specificat \u00een gazda virtual\u0103 a site-ului clientului. <\/p>\n

Despre func\u021bionarea schemei Shared se poate citi mai detaliat \u00een prima parte a articolului<\/a><\/noindex>.<\/p>\n

\"Apache
\nSchema Shared <\/i><\/p>\n

Este important de men\u021bionat c\u0103 instal\u0103m pachete PHP pentru diferite versiuni, deoarece de obicei \u00een toate distribu\u021biile exist\u0103 doar o singur\u0103 versiune PHP. <\/p>\n

Siguran\u021ba mai presus de toate!<\/h4>\n

\nUna dintre cele mai importante sarcini ale g\u0103zduirii virtuale este asigurarea siguran\u021bei datelor clientului. Conturile diferite, aflate pe acela\u0219i server, sunt autonome \u0219i independente. Cum func\u021bioneaz\u0103 acest lucru?<\/p>\n

Fi\u0219ierele site-urilor sunt stocate \u00een directoarele de acas\u0103 ale utilizatorilor, iar \u00een gazda virtual\u0103 a serverelor web sunt specificate c\u0103ile necesare. Este important ca serverele web, Nginx \u0219i Apache, s\u0103 aib\u0103 acces la fi\u0219ierele finale ale unui client, deoarece serverul web porne\u0219te doar pentru un singur utilizator. <\/p>\n

Pentru Nginx se folose\u0219te un patch de securitate, dezvoltat de echipa Timeweb: acest patch schimb\u0103 utilizatorul cu cel specificat \u00een fi\u0219ierul de configurare al serverului web. <\/p>\n

Al\u021bi furnizori de g\u0103zduire pot rezolva aceast\u0103 problem\u0103, de exemplu, prin manipul\u0103ri cu drepturi extinse ale sistemului de fi\u0219iere (ACL).<\/p>\n

Pentru func\u021bionarea Apache se folose\u0219te un modul de multiprocesare mpm-itk<\/a><\/noindex>. Acesta permite rularea fiec\u0103rui VirtualHost cu un identificator de utilizator \u0219i un ID de grup proprii.
\n\"Apache
\nAstfel, datorit\u0103 opera\u021biunilor descrise mai sus, ob\u021binem un mediu izolant sigur pentru fiecare client. De asemenea, rezolv\u0103m problemele de scalabilitate pentru hosting-ul Shared. <\/p>\n

Despre cum este realizat\u0103 leg\u0103tura \u00eentre Apache \u0219i Nginx, pute\u021bi citi \u00een prima parte<\/a><\/noindex> articolul nostru. \u00cen plus, acolo este descris\u0103 \u0219i o configura\u021bie alternativ\u0103 prin schema Dedicated.<\/p>\n

Dac\u0103 ave\u021bi \u00eentreb\u0103ri pentru exper\u021bii no\u0219tri, scrie\u021bi \u00een comentarii. Ne vom str\u0103dui s\u0103 r\u0103spundem la tot sau s\u0103 descriem solu\u021bia mai detaliat \u00een articolele urm\u0103toare.
