Jag vill dela med mig av min erfarenhet av att \u00f6vers\u00e4tta Apache 2.4 till PCRE2, eftersom \u00e4ven PHP 7 l\u00e4nge har st\u00f6ttat biblioteket PCRE2, men open source Apache Software Foundation fortfarande inte g\u00f6r det.
\nSj\u00e4lvklart kanske jag nu ligger f\u00f6re releasen av Apache med st\u00f6d f\u00f6r PCRE2, eftersom jag anv\u00e4nder k\u00e4llkoden fr\u00e5n Apache's git, vilket inneb\u00e4r att st\u00f6d f\u00f6r PCRE2 redan kan komma i n\u00e4sta release. Men f\u00f6r dem som redan nu vill ha st\u00f6d f\u00f6r PCRE2 i Apache 2.4 och inte vill v\u00e4nta p\u00e5 releasen, delar jag med mig av ett av s\u00e4tten.<\/p>\n

Artikeln f\u00f6ruts\u00e4tter att du samlar all n\u00f6dv\u00e4ndig mjukvara fr\u00e5n k\u00e4llkoden. Lista \u00f6ver mjukvara och versioner vid tidpunkten av artikelskrivning:<\/p>\n

PCRE2-10.33
\nAPR 1.7.0
\nAPR-util 1.6.1
\nApache httpd 2.4.41<\/b><\/p>\n

Steg ett: samla och kompilera PCRE2<\/h3>\n

\nVi hoppar \u00f6ver steget f\u00f6r att ladda ner k\u00e4llkoder fr\u00e5n officiella k\u00e4llor, eftersom det \u00e4r f\u00f6r uppenbart. S\u00e5, du har packat upp arkivet, g\u00e5 till mappen med PCRE2-k\u00e4llkoden och k\u00f6r f\u00f6ljande kommando f\u00f6r att st\u00f6dja UTF:<\/p>\n

.\\\/configure --prefix=\\\/etc\\\/webserver\\\/pcre2-1033 --enable-pcre2-8 --enable-pcre2-16 --enable-pcre2-32 --enable-unicode<\/code><\/pre>\n
\nI prefixet anger du din v\u00e4g om du inte vill anv\u00e4nda den standardplats som biblioteket ska installeras p\u00e5:<\/p>\n
--prefix=\\\/din\\\/v\u00e4g\\\/till biblioteket<\/code><\/pre>\n
\nAnnars kompilerar du utan prefix.<\/p>\n
De andra kommandona anger att st\u00f6d ska inkluderas f\u00f6r 8-bitars, 16-bitars och 32-bitars PCRE kodblock, i detta fall har byggandet genomf\u00f6rts med dem.<\/p>\n
Och sj\u00e4lvklart kompilerar vi detta genom att utf\u00f6ra kommandona i f\u00f6ljd:<\/p>\n
make\nmake install<\/code><\/pre>\n
\nOm allt \u00e4r bra och kompileringen gick utan fel, g\u00e5r vi vidare till n\u00e4sta steg.
\n<\/a><\/noindex><\/p>\n
Steg tv\u00e5: ansluta PCRE2-biblioteket i APR<\/h3>\n
\nEftersom Apache kompilerar k\u00e4llkoden med hj\u00e4lp av APR, beh\u00f6ver vi ansluta biblioteket i sj\u00e4lva APR, annars kan det uppst\u00e5 fel om ok\u00e4nda funktioner i Apache:s k\u00e4llkod, eftersom vi kommer att anv\u00e4nda nya funktioner fr\u00e5n PCRE2.<\/p>\n
Vi hoppar \u00f6ver steget f\u00f6r att ladda ner k\u00e4llkoder fr\u00e5n officiella k\u00e4llor, eftersom det \u00e4r f\u00f6r uppenbart. S\u00e5, du har packat upp arkivet och konfigurerat APR:<\/p>\n
.\\\/configure --prefix=\\\/etc\\\/webserver\\\/apr-170<\/code><\/pre>\n
\nSj\u00e4lvklart anger du din v\u00e4g i prefixet om du inte vill anv\u00e4nda den standardplats som biblioteket ska installeras p\u00e5, eller s\u00e5 anger du inget:<\/p>\n
--prefix=\\\/din\\\/v\u00e4g\\\/till biblioteket<\/code><\/pre>\n
\nEfter att ha utf\u00f6rt konfigurationen g\u00e5r du till katalogen: \\\/etc\\\/webserver\\\/srcsrv\\\/apr-1.7.0\\\/build<\/p>\n
Eller: \\\/din\\\/v\u00e4g\\\/till biblioteket\\\/build<\/p>\n
Hitta filen apr_rules.mk i den h\u00e4r katalogen och l\u00e4gg till i slutet av raden d\u00e4r:<\/p>\n
EXTRA_LIBS=-lrt -lcrypt  -lpthread -ldl<\/code><\/pre>\n
\nAnslutning av biblioteket:<\/p>\n
-lpcre2-8 -L\\\/din\\\/v\u00e4g\\\/till biblioteket pcre2\\\/lib<\/code><\/pre>\n
\nVi sparar och g\u00e5r till rotkatalogen f\u00f6r APR-k\u00e4llkoden: \/din\/s\u00f6kv\u00e4g\/till\/biblioteket.<\/p>\n
Vi kompilerar v\u00e5r \u00e4ndrade APR:<\/p>\n
make\nmake install<\/code><\/pre>\n
\nOm allt \u00e4r bra och kompileringen gick utan fel, g\u00e5r vi vidare till n\u00e4sta steg.<\/p>\n
Steg tre: vi bygger APR-util fr\u00e5n k\u00e4llkoden f\u00f6r Apache<\/h3>\n
\nDu har laddat ner detta bibliotek fr\u00e5n den officiella k\u00e4llan, g\u00e5 till rotmappen f\u00f6r den uppackade APR-util-arkivet och skriv in f\u00f6ljande kommandon:<\/p>\n
.\/configure --prefix=\/etc\/webserver\/apr-util-161 --with-apr=\/din\/s\u00f6kv\u00e4g\/till\/biblioteket\/apr\nmake\nmake install<\/code><\/pre>\n
\nSj\u00e4lvklart anger du din v\u00e4g i prefixet om du inte vill anv\u00e4nda den standardplats som biblioteket ska installeras p\u00e5, eller s\u00e5 anger du inget:<\/p>\n
--prefix=\\\/din\\\/v\u00e4g\\\/till biblioteket<\/code><\/pre>\n
\nH\u00e4r kopplar vi ocks\u00e5 in v\u00e5r APR:<\/p>\n
--with-apr=\/din\/s\u00f6kv\u00e4g\/till\/biblioteket\/apr<\/code><\/pre>\n
<\/p>\n
Steg fyra: laddar ner k\u00e4llkoden fr\u00e5n Apache Git f\u00f6r att st\u00f6dja PCRE2<\/h3>\n
\nViktigt: Ladda ner k\u00e4llkoden fr\u00e5n den senaste versionen p\u00e5 Git.<\/p>\n
Vi beh\u00f6ver ladda ner tv\u00e5 k\u00e4llfiler, n\u00e4mligen ap_regex.h och util_pcre.c, l\u00e4nkarna nedan:
\nap_regex.h<\/a><\/noindex>
\nutil_pcre.c<\/a><\/noindex><\/p>\n
Nu g\u00e5r vi till din Apache httpd-k\u00e4llkodskatalog och bygger Apache med f\u00f6ljande kommandon:<\/p>\n
.\/configure --prefix=\/etc\/webserver\/apache-2441 --with-apr=\/din\/s\u00f6kv\u00e4g\/till\/biblioteket\/apr --with-apr-util=\/din\/s\u00f6kv\u00e4g\/till\/biblioteket\/apr-util --with-pcre=\/din\/s\u00f6kv\u00e4g\/till\/biblioteket\/pcre2\/bin\/pcre2-config<\/code><\/pre>\n
\nSj\u00e4lvklart anger du din v\u00e4g i prefixet om du inte vill anv\u00e4nda den standardplats som biblioteket ska installeras p\u00e5, eller s\u00e5 anger du inget:<\/p>\n
--prefix=\/din\/s\u00f6kv\u00e4g\/till\/Apache httpd<\/code><\/pre>\n
\nDu kan ocks\u00e5 ange ytterligare kommandon f\u00f6r att bygga Apache efter eget val, jag menar kommandon f\u00f6r att aktivera eller inaktivera moduler och bibliotek.<\/p>\n
Vidare g\u00e5r vi till din Apache httpd-k\u00e4llkodskatalog, f\u00f6r mig \u00e4r det:<\/p>\n
\/etc\/webserver\/srcsrv\/httpd-2.4.41<\/code><\/pre>\n
\nDu g\u00e5r sj\u00e4lvklart till din katalog, vi byter ut i katalogen:<\/p>\n
\/etc\/webserver\/srcsrv\/httpd-2.4.41\/include<\/code><\/pre>\n
\nFilen ap_regex.h mot den vi laddade ner fr\u00e5n Apache Git.<\/p>\n
Vi g\u00e5r ocks\u00e5 till katalogen:<\/p>\n
\/etc\/webserver\/srcsrv\/httpd-2.4.41\/server<\/code><\/pre>\n
\nVi byter ut filen util_pcre.c mot den vi laddade ner fr\u00e5n Apache Git<\/p>\n
Nu \u00e5terst\u00e5r det att l\u00e4gga till PCRE2-st\u00f6d i Apache, vi beh\u00f6ver hitta filen ap_config_auto.h, den finns i katalogen:<\/p>\n
\/etc\/webserver\/srcsrv\/httpd-2.4.41\/include<\/code><\/pre>\n
\nI b\u00f6rjan av denna fil ska du klistra in f\u00f6ljande rader:<\/p>\n
\/* Load PCRE2 *\/\n#define HAVE_PCRE2 1<\/code><\/pre>\n
\nNu \u00e4r vi redo f\u00f6r det verkliga kompilerings\u00f6gonblicket f\u00f6r Apache httpd med PCRE2-st\u00f6d.
\nVi g\u00e5r till din Apache httpd-k\u00e4llkodskatalog, och kompilerar detta genom att utf\u00f6ra kommandona i f\u00f6ljd:<\/p>\n
make\nmake install<\/code><\/pre>\n
\nOm allt har g\u00e5tt bra och utan fel, s\u00e5 kommer du att ha en kompilerad Apache httpd med PCRE2-st\u00f6d, vilket inneb\u00e4r positiva f\u00f6r\u00e4ndringar i Apache-moduler som anv\u00e4nder PCRE-regulj\u00e4ra uttryck, ett s\u00e5dant \u00e4r Module rewrite.<\/p>\n
Avslutningsvis ger denna metod m\u00f6jlighet att anv\u00e4nda PCRE2 f\u00f6re den officiella utg\u00e5van fr\u00e5n Apache Software Foundation, jag hoppas att det snart kommer en version med PCRE2-st\u00f6d.<\/p>\n
Under testningen av standard .htaccess uppstod inga fel, om n\u00e5gon f\u00e5r fel s\u00e5 skriv i kommentarerna.<\/p>\n
P.S.<\/h3>\n
\nJag k\u00e4nde mig lite stressad \u00f6ver situationen med att anv\u00e4nda tv\u00e5 olika versioner av PCRE f\u00f6r min stack, s\u00e5 jag best\u00e4mde mig f\u00f6r att \u00e5tg\u00e4rda det.
