Ungayifaka kanjani iJava ekusatshalalisweni okuhlukile kweLinux?

IJava ulimi lokuhlela futhi ngasikhathi sinye ipulatifomu ebalulekile Isebenza ezinhlelweni eziningi zesimanje zokusebenza.

Isetshenziselwa izinhloso ezahlukahlukene futhi kungumphelelisi obalulekile wokuqalwa nokusebenza kwamathuluzi ahlukahlukene.

I-OpenJDK ingumthombo womphakathi ovulekile we-Java. Isetshenziswa kabanzi ngoba itholakala ngokuzenzakalela ku-Ubuntu kanye nokusatshalaliswa okuningi kwe-Linux.

Nokho, ngeke isetshenziselwe ukuthuthukisa izinhlelo zentengiso. IJava wulimi lohlelo oluqondiswe entweni oluphethwe yi-Oracle. Ulimi oluhlanganisiwe, lunemithetho yalo futhi lusatshalaliswa kabanzi emazingeni ezemfundo nawobungcweti.

Ngenxa yelayisense yayo, iJava ayifakiwe ngokuzenzakalela ekusatshalalisweni okuningi kweLinux. Ngalokho, ukuze ube neJava ekusatshalalisweni kwakho, kufanele uyifake ngokwakho.

IJava iyahambisana neLinux, lokhu kusho ukuthi kungenzeka ukusebenzisa nokwakha izinhlelo ekusakazeni okuthandayo.

Ukufaka iJava ekusabalalisweni okuhlukile kweLinux

Njengoba kushiwo, Ukufakwa kweJava ekusatshalalisweni okuhlukile kweLinux kwehlukile ngakunye, kanjalo Kufanele ulandele imiyalo esabelana ngayo nawe, ngokusatshalaliswa kwe-Linux oyisebenzisayo.

Ukufaka i-Oracle Java 11 ku-Ubuntu 18.10 kanye nokuphuma kwayo futhi sikwazi ukuthola izibuyekezo ezizenzakalelayo kuyo ngokuzenzakalela, kufanele senze okulandelayo:

Ubuntu kanye nokuphuma kokunye

Endabeni ye-Ubuntu 18.10, Ubuntu 18.04 kanye nokuphuma kokunye, sizovula i-terminal kuhlelo, Ungasebenzisa okhiye be-CTRL + ALT + T njengesinqamuleli futhi esibulalayo sizothayipha umyalo olandelayo ukwengeza okugciniwe ohlelweni:

sudo add-apt-repository ppa:linuxuprising/java

Uma lokhu sekwenziwe, kufanele siqabule kabusha amakhosombe namaphakeji ngomyalo:

sudo apt-get update

Okokugcina singafaka iJava nge:

sudo apt install oracle-java11-installer

Debian

Uma kunjalo Abasebenzisi be-Debian noma ukusatshalaliswa okususelwe kukho njenge-Neptune OS, i-Deepin OS nabanye,  Kufanele sivule ukuphela bese senza izinyathelo ezimbalwa ngaphambi kokufaka ngqo iJava kusistimu yethu.

Esigungwini sizothayipha:

sudo -i
apt install wget libasound2 libasound2-data

Kwenziwe lokhu manje sizolanda iphakethe lesikweletu le-Java 11 nge:

wget --no-cookies --no-check-certificate --header "Cookie: oraclelicense=accept-securebackup-cookie" \
http://download.oracle.com/otn-pub/java/jdk/11+28/55eed80b163941c8885ad9298e6d786a/jdk-11_linux-x64_bin.deb

Ekugcineni sifaka nge:

dpkg -i jdk-11_linux-x64_bin.deb

Kwenziwe lokhu manje sizosetha iJava 11 njengenguqulo ezenzakalelayo:

update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-11/bin/java 2
update-alternatives --config java

I-Arch Linux kanye nokuphuma kokunye

Endabeni yalabo abangabasebenzisi be-Arch Linux, i-Antergos, iManjaro noma yikuphi okunye ukusatshalaliswa okususelwa ku-Arch Linux, bangafaka iJava kalula.

Odinga ukukwenza nje ukuthi indawo yokugcina i-AUR ingezwe kufayela lakho le-pacman.conf futhi ube newizard yokufaka amaphakheji we-AUR kusistimu yakho.

Uma ungenayo, ungayisebenzisa Ngincoma kokuthunyelwe okulandelayo.

Manje kufanele uvule ukuphela bese wenza umyalo olandelayo:

yay -S jdk

Futhi usulungile, Kumele ulinde ukuhlanganiswa kwalokhu ukuthi kwenziwe futhi kuzokucela ekugcineni ukuthayipha iphasiwedi yakho ukwenza ukufakwa.

RHEL, CentOS, Fedora, OpenSUSE kanye nokuphuma

Endabeni ye Labo bethu abangabasebenzisi bokusatshalaliswa ngokusekelwa kwamaphakeji e-RPM bangafaka iJava kusistimu yethu ngosizo lwephakeji elilandelayo, esizolanda ngosizo lwe-terminal yethu:

wget "https://download.oracle.com/otn-pub/java/jdk/11.0.1+13/90cf5d8f270a4347a95050320eef3fb7/jdk-11.0.1_linux-x64_bin.rpm?AuthParam=1540738418_ef8759a34917876432dbb9d668d4b5e4" -O java11.rpm

Manje Ukuqala ngokufakwa, esimweni kuphela se-openSUSE sizofaka iphakheji nge:

sudo zypper install java11.rpm

Ekugcineni, Ukufaka ku-Fedora, i-RedHat kanye nokuphuma kwayo, ungakwenza ngomyalo olandelayo:

sudo yum localinstall java11.rpm

Noma ngalo myalo bangakwenza futhi:

sudo dnf install java11.rpm

Ungahlola kanjani ukuthi iJava ifakwe kahle?

Ngemuva kokwenza ukufakwa okulungile kweJava kusistimu yethu, Singaqinisekisa ukuthi sine-Java version 11 efakwe ohlelweni lwethu ngomyalo olandelayo:

java --version
