Indlela Yokuthola I-Oracle Java Runtime Environment Esemthethweni (JRE) Ubuntu
Kunezinguqulo ezimbili ze-Java Runtime Environment etholakalayo. I-version esemthethweni ikhishwa ngu-Oracle. Le nguqulo ayitholakali nge-"Ubuntu Software" ithuluzi elisetshenziselwa ukufaka izicelo ku-Ubuntu.
Iwebhusayithi ye-Oracle ayifaki iphakethe le-Debian noma. Amaphakheji we-Debian ane-extension ".deb" asefomethi elula ukufaka ngaphakathi kwe-Ubuntu.
Kunalokho kufanele ufake iphakheji ngokufaka ngefayili ye-"tar". Ifayela "i-tar" ngokuyinhloko uhlu lwamakholi wonke agcinwe ngaphansi kwegama elilodwa lefayela lapho efakwe khona amafayela kumafolda awo afanele.
Enye i-Java Runtime Environment iyatholakala ehlukile ebizwa nge-OpenJDK. Le nguqulo ayitholakali ngethuluzi le-"Ubuntu Software" kodwa itholakala kumlayini wokulayisha usebenzisa ukuzuza.
Uma uhlose ukuthuthukisa izinhlelo zeJava uzofuna ukufaka i-Java Development Kit (JDK) esikhundleni se-Java Runtime Environment (JRE). Njengama-Runtime Environments ama-Java amaKhrojekthi Okuthuthukiswa atholakale njengephakheji esemthethweni ye-Oracle noma iphakheji evulekile yomthombo.
Lo mhlahlandlela uzokukhombisa ukuthi ungafaka kanjani kokubili i-Oracle Runtime and Development Kits kanye nemithombo evulekile yomthombo.
Ukuze uqale ukufaka inguqulo esemthethweni ye-Oracle noma i-Java Runtime Environment vakashela ku-https://www.oracle.com/uk/java/index.html.
Uzobona izixhumanisi ezingu-2 zitholakalayo:
- I-Java Yabathuthukisi
- I-Java Yabathengi
Ngaphandle kokuthi uhlose ukuthuthukisa izinhlelo ze-Java kufanele uchofoze kusixhumanisi se- "Java For Consumer".
Manje uzobona inkinobho enkulu ebomvu ebizwa ngokuthi "I-Free Java Download".

Indlela Yokufaka i-Official Oracle Java Runtime For Ubuntu
Ikhasi lizovela ngezixhumanisi ezingu-4 kuso:
- I-Linux RPM
- Linux
- I-Linux x64
- I-Linux x64 RPM
Amafayela we- Linux RPM ne-Linux x64 RPM awawubheki we-Ubuntu ngakho ungawabheka lezo zixhumanisi.
Isixhumanisi se-Linux inguqulo engu-32-bit ye-Java Runtime kanye nesixhumanisi se-Linux x64 yinguqulo engu-64-bit ye-Java Runtime.
Uma unekhompyutha ye-64-bit cishe uzofuna ukufaka ifayili le-Linux x64 futhi uma unomshini we-32-bit uzofuna ukufaka ifayela le-Linux.
Ngemuva kokuthi ifayela elifanele lilande livule iwindi lokugcina . Indlela elula yokuvula iwindi lokugcina ku-Ubuntu ukucindezela i-CTRL, ALT no-T ngesikhathi esifanayo.
Into yokuqala okufanele uyenze ukuthola igama lefayela langempela elilayishiwe kusuka kuwebhusayithi ye-Oracle. Ukuze wenze lokhu qalisa imiyalo elandelayo:
cd ~ / Ukulanda
ls jre *
Umyalo wokuqala uzoshintsha isiqondisi kufolda yakho "Yokulanda". Umyalo wesibili unikeza uhlu lwemibhalo lwazo zonke amafayela aqala nge "jre".
Manje kufanele ubone igama lomsebenzisi libheke into enjengale:
jre-8u121-linux-x64.tar.gz
Thatha inothi legama lefayela noma ukhethe ngegundane, chofoza ngakwesokudla bese ukhetha ikhophi.
Isinyathelo esilandelayo ukuhamba lapho uhlela khona ukufaka iJava bese ususa ifayela le-tar elifakiwe.
Qalisa imiyalo elandelayo:
sudo mkdir / usr / java
cd / usr / java
sudo tar zxvf ~ / Ukulanda / jre-8u121-linux-x64.tar.gz
Amafayela manje azokhishwa kufolda / usr / java futhi yilokho.
Ukukhipha ifayela elilandiwe sebenzisa umyalo olandelayo:
sudo rm ~ / Ukulanda / jre-8u121-linux-x64.tar.gz
Isinyathelo sokugcina ukuvuselela ifayela lakho lezemvelo ukuze ikhompyutha yakho ikwazi ukuthi i-Java ifakiwe nokuthi iyiphi ifolda i-JAVA_HOME.
Qalisa umyalo olandelayo ukuvula ifayela lezemvelo kumhleli we-nano:
sudo nano / njll / imvelo
Pheqa kuze kube sekupheleni komugqa oqala PATH = nangaphambi kokugcina "faka lokhu okulandelayo
: /usr/java/jre1.8.0_121/bin
Bese wengeza umugqa olandelayo:
JAVA_HOME = "/ usr / java / jre1.8.0_121"
Londoloza ifayela ngokucindezela i-CTRL no-O bese uphuma umhleli ngokucindezela i-CTRL no-X.
Ungahlola ukuthi i-Java isebenza ngokuthayipha umyalo olandelayo:
i-java -version
Kufanele ubone imiphumela elandelayo:
Inguqulo ye-Java 1.8.0_121

Indlela Yokufaka I-Official Oracle Java Development Kit Ukuze Ubuntu
Uma uhlela ukuthuthukisa isofthiwe usebenzisa i-Java ungafaka i-Java Development Kit esikhundleni se-Java Runtime Environment.
Vakashela i-https: //www.oracle.com/uk/java/index.html bese ukhetha inketho ethi "Java For Developers".
Uzobona ikhasi elididekayo ngokuxhumana okuningi. Bheka isixhumanisi esibizwa nge- "Java SE" esithatha kuleli khasi.
Kukhona izinketho ezimbili ezengeziwe:
- Faka i-Java JDK
- Faka iNetbeans
I-Java JDK ifaka iKitjhi yokuThuthukiswa kweJava nje. Inketho ye-Netbeans ifaka imvelo yokuhlanganiswa okugcwele kanye ne-Java Development Kit.
Uma uchofoza ku-Java JDK uzobona izinombolo eziningi. Njengendawo ye-runtime uzodinga ifayela le-Linux x86 ye-32-bit version ye-kit yokuthuthukisa noma ifayela le-Linux x64 le-64-bit version. Awufuni ukuchofoza kuzixhumanisi ze-RPM, esikhundleni sokuchofoza kusixhumanisi esiphela ku- " tar.gz ".
Njengoba nge-Java Runtime Environment uzodinga ukuvula iwindi lokugcina bese ucinga ifayili oyilandile.
Ukuze wenze lokhu qalisa imiyalo elandelayo:
cd ~ / Ukulanda
ls jdk *
Umyalo wokuqala uzoshintsha isiqondisi kufolda yakho "Yokulanda". Umyalo wesibili unikeza uhlu lwemibhalo lwazo zonke amafayela aqala ngo- "jdk".
Manje kufanele ubone igama lomsebenzisi libheke into enjengale:
jdk-8u121-linux-x64.tar.gz
Thatha inothi legama lefayela noma ukhethe ngegundane, chofoza ngakwesokudla bese ukhetha ikhophi.
Isinyathelo esilandelayo ukuhamba lapho uhlela khona ukufaka ithuluzi lokuthuthukiswa futhi ususe ifayela eliyi-tar elifakwe.
Qalisa imiyalo elandelayo:
sudo mkdir / usr / jdk
cd / usr / jdk
sudo tar zxvf ~ / Ukulanda / jdk-8u121-linux-x64.tar.gz
Amafayela manje azokhishwa kufolda / usr / java futhi yilokho.
Ukukhipha ifayela elilandiwe sebenzisa umyalo olandelayo:
sudo rm ~ / Ukulanda / jdk-8u121-linux-x64.tar.gz
Isinyathelo sokugcina njengendawo yokugijimela ukuvuselela ifayela lakho lemvelo ukuze ikhompyutha yakho ikwazi ukuthi i-JDK ifakiwe nokuthi iyiphi ifolda i-JAVA_HOME.
Qalisa umyalo olandelayo ukuvula ifayela lezemvelo kumhleli we-nano :
sudo nano / njll / imvelo
Pheqa kuze kube sekupheleni komugqa oqala PATH = nangaphambi kokugcina "faka lokhu okulandelayo
: /usr/jdk/jdk1.8.0_121/bin
Bese wengeza umugqa olandelayo:
JAVA_HOME = "/ usr / jdk / jdk1.8.0_121"
Londoloza ifayela ngokucindezela i-CTRL no-O bese uphuma umhleli ngokucindezela i-CTRL no-X.
Ungahlola ukuthi i-Java isebenza ngokuthayipha umyalo olandelayo:
i-java -version
Kufanele ubone imiphumela elandelayo:
Inguqulo ye-Java 1.8.0_121

Indlela Engcono Yokufaka I-Oracle Version Ye-Java Ebusayo Ubuntu
Uma ukusetshenziswa kwe-terminal ye-Linux ukuthi awukhululekile nawe ungasebenzisa amathuluzi okudweba ukufaka inguqulo esemthethweni ye-Java Runtime Environment and Development Kits.
Lokhu kudinga ukufaka ingobo yomlando yangaphandle yephakeji (PPA). I- PPA iyinqolobane yangaphandle enganikezwa yi-Canonical noma Ubuntu.
Isinyathelo sokuqala ukufaka isiqephu sesofthiwe esibizwa ngokuthi "Synaptic". I-Synaptic iyimenenja yephakheji ecacile . Ihluke kwi-"Ubuntu Software" ithuluzi lokuthi libuyisela yonke imiphumela etholakalayo kuma-software akho atholakalayo.
Ngeshwa ukuze ufake i-Synaptic udinga ukusebenzisa i-terminal kodwa ngempela umyalo owodwa nje. Vula ukuphela ngokucindezela i-CTRL, ALT no-T ngesikhathi esifanayo.
Faka umyalo olandelayo:
sudo apt-get ukufaka i-synaptic
Ukuqalisa ukuchofoza kwe-Synaptic esithombeni phezulu kwe-bar yokuqalisa bese uthayipha i- "Synaptic". Uma isithonjana sibonakala uchofoze kuso.
Chofoza ku-"Izilungiselelo" imenyu bese ukhetha "Okuthunyelwe".
Isikrini se- "Software and Updates" sizovela.
Chofoza kuthebhu ebizwa ngokuthi "enye i-Software".
Chofoza inkinobho ethi "Engeza" bese ufaka okulandelayo efasiteleni elivela:
ppa: webupd8team / java
Chofoza inkinobho ethi "Vala".
I-synaptic manje izocela ukuthi ilayishe kabusha ama-repositories ukuze udonse ohlwini lwamagama we-software avela ku-PPA ovele wengeze.

Faka i-Oracle JRE ne-JDK usebenzisa i-Synaptic
Manje usungashayela i-Oracle Java Runtime Environment ne-Java Development Kits usebenzisa isici sokusesha ngaphakathi kwe-Synaptic.
Chofoza inkinobho ethi "Sesha" bese ufaka i- "Oracle" ebhokisini. Chofoza inkinobho ethi "Usesho".
Uhlu lwamaphakheji atholakalayo anegama elithi "Oracle" lizovela.
Manje ungakhetha ukuthi ukufaka imvelo yokugijima noma ithuluzi lokuthuthukiswa. Akukhona nje kuphela ukuthi ungakhetha ukuthi iyiphi inguqulo ongayifaka.
Njengamanje kungenzeka ukufaka ukubuyela emuva njengo-Oracle 6 kuze kufike i-Oracle 9 entsha engakhululwa ngokugcwele. Inguqulo enconyiwe ngu-Oracle 8.
Ukufaka empeleni indawo yephakheji isheke ebhokisini eceleni kwento oyifisa ukuyifaka bese uchofoza inkinobho ethi "Faka isicelo".
Ngesikhathi kokufakwa uzocelwa ukuba wamukele ilayisensi ye-Oracle.
Lokhu empeleni umzila olula kakhulu ukufaka i-Oracle kodwa isebenzisa i-PPA yangaphandle futhi ngakho akukho okuqinisekisayo ukuthi lokhu kuzohlale kuyindlela ekhona.

Indlela Yokufaka I-Open Source Java Runtime neJava Development Kit
Uma ukhetha ukusebenzisa kuphela isofthiwe yomthombo ovulekile futhi ungafaka izinguqulo ezivulekile zemiklamo ye-Java Runtime neNtuthuko.
Uzodinga ukufaka i-Synaptic ukuze uqhubeke futhi uma ungafundi ikhasi langaphambilini indlela yokwenza lokhu kanje:
- Vula iwindi lokugcina ngokucindezela i-CTRL, ALT no-T
- Faka umyalo olandelayo efasiteleni lokugcina:
sudo apt-get ukufaka i-synaptic
Ukuqalisa ukuchofoza kwe-Synaptic esithombeni phezulu kwe-bar yokuqalisa bese uthayipha i- "Synaptic". Uma isithonjana sibonakala uchofoze kuso.
Ngaphakathi kwe-Synaptic konke okudingeka ukwenze ukuchofoza inkinobho ethi "Sesha" phezulu kwesikrini bese usesha i- "JRE".
Uhlu lwezicelo lufaka phakathi "Okuzenzakalelayo i-JRE" yenguqulo evulekile yomthombo we-Java Runtime Environment noma i- "OpenJDK".
Ukufuna inguqulo yomthombo ovulekile we-Java Development Kit chofoza inkinobho ethi "Cinga" bese usesha i- "JDK". Okukhethwa kukho okuthiwa i- "OpenJDK JDK" kuzovela.
Ukufaka indawo yephakheji umaki ebhokisini eceleni kwento ofuna ukuyifaka bese uchofoze "Faka isicelo".
