Qhov kev qhia no yuav npog kev txhim kho ob qho 32-ntsis thiab 64-ntsis Oracle Java 7 JDK/JRE (tus lej tam sim no yog 1.7.0_45) ntawm 32-ntsis thiab 64-ntsis Ubuntu kev ua haujlwm. Phau ntawv qhia no tseem siv rau Debian thiab Linux Mint. Rau cov uas koj xwb xav nruab Oracle Java JRE kom khiav Java daim ntawv thov thiab tsis tsim Java cov haujlwm, siv txoj hauv kev no:
Txhim kho Oracle Java JRE ntawm Linux Ubuntu
Rau cov ntawm koj uas xav teeb tsa Oracle Java JDK txhawm rau txhim kho Java cov haujlwm thiab cov ntawv thov (Oracle Java JRE tseem suav nrog hauv Oracle JDK), siv txoj hauv kev no:
Txhim kho Oracle Java JDK ntawm Ubuntu Linux
Kauj ruam
Kauj Ruam 1. Txheeb xyuas yog tias koj li Ubuntu Linux operating system yog 32-ntsis lossis 64-ntsis architecture
Qhib lub davhlau ya nyob twg thiab khiav cov lus txib hauv qab no.
-
Hom/Luam/Muab Tshuaj:
cov ntaub ntawv /sbin /init
Qhov me ntsis ntawm koj li Ubuntu Linux kev ua haujlwm kev tsim qauv yuav tso tawm raws li 32-ntsis lossis 64-ntsis
Kauj Ruam 2. Txheeb xyuas yog tias Java tau teeb tsa hauv koj lub kaw lus lawm
Txhawm rau ua qhov no, koj yuav tsum tau khiav Java version ntawm cov lus txib los ntawm lub davhlau ya nyob twg.
-
Qhib lub davhlau ya nyob twg thiab nkag mus rau cov lus txib hauv qab no:
-
Hom/Luam/Muab Tshuaj:
java -version
-
-
Yog tias OpenJDK twb tau teeb tsa hauv kab ke, cov ntawv hauv qab no yuav tshwm ntawm qhov screen:
-
java version "1.7.0_15"
OpenJDK Runtime Environment (IcedTea6 1.10pre) (7b15 ~ pre1-0lucid1)
OpenJDK 64-Bit Server VM (tsim 19.0-b09, hom sib xyaw)
-
- Yog tias OpenJDK twb tau teeb tsa ntawm koj lub kaw lus, nws txhais tau tias koj muaj tus muag khoom tsis raug ntawm Java rau txoj kev no.
Kauj Ruam 3. Tshem OpenJDK/JRE los ntawm koj lub kaw lus thiab tsim cov npe los tuav koj li Oracle Java JDK/JRE binary
Qhov no yuav tiv thaiv lub kaw lus los ntawm kev ntsib teeb meem thiab tsis meej pem vim txawv version ntawm cov neeg muag khoom Java. Piv txwv li, yog tias koj muaj OpenJDk/Jre teeb tsa ntawm koj lub kaw lus, koj tuaj yeem tshem nws los ntawm kev ntaus kab lus hais hauv qab no:
-
Hom/Luam/Muab Tshuaj:
sudo apt-tau tshem tawm openjdk-\*
Cov lus txib no yuav tshem tawm OpenJDK/JRE tag nrho los ntawm koj lub system
-
Hom/Luam/Muab Tshuaj:
sudo mkdir -p/usr/zos/java
Cov lus txib no yuav tsim cov npe los tuav koj li Oracle Java JDK thiab JRE binaries
Kauj Ruam 4. Rub Oracle Java JDK/JRE rau Linux
Nco ntsoov tias koj xaiv compressed binary txoj cai rau 32-ntsis lossis 64-ntsis system architectures (cov uas xaus rau hauv tar.gz).
- Piv txwv li, yog tias koj siv 32-ntsis Ubuntu Linux kev ua haujlwm, rub tawm 32-ntsis Oracle Java binary.
- Piv txwv li, yog tias koj siv 64-ntsis Ubuntu Linux operating system, rub tawm 64-ntsis Oracle Java binary.
-
Yeem, Rub tawm Oracle Java JDK/JRE Cov ntaub ntawv
Xaiv jdk-7u40-apidocs.zip
-
Cov Ntaub Ntawv Tseem Ceeb:
64-ntsis Oracle Java binary tsis ua haujlwm ntawm 32-ntsis Ubuntu Linux kev ua haujlwm. Yog tias koj sim teeb tsa 64-ntsis Oracle Java ntawm 32-ntsis Ubuntu Linux, koj yuav tau txais ntau cov kab lus yuam kev.
Kauj Ruam 5. Luam Oracle Java binary mus rau/usr/local/java directory
Feem ntau Oracle Java binary yuav raug rub mus rau: /home /"koj_user_name"/Rub tawm.
