CentOS線上安裝JDK，centos線上jdk

CentOS線上安裝JDK，centos線上jdk

一、通過yum命令線上安裝jdk

1.查看雲端目前支援安裝的jdk版本

[root@localhost ~]# yum search java|grep jdkldapjdk-javadoc.noarch : Javadoc for ldapjdkjava-1.6.0-openjdk.x86_64 : OpenJDK Runtime Environmentjava-1.6.0-openjdk-demo.x86_64 : OpenJDK Demosjava-1.6.0-openjdk-devel.x86_64 : OpenJDK Development Environmentjava-1.6.0-openjdk-javadoc.x86_64 : OpenJDK API Documentationjava-1.6.0-openjdk-src.x86_64 : OpenJDK Source Bundlejava-1.7.0-openjdk.x86_64 : OpenJDK Runtime Environmentjava-1.7.0-openjdk-accessibility.x86_64 : OpenJDK accessibility connectorjava-1.7.0-openjdk-demo.x86_64 : OpenJDK Demosjava-1.7.0-openjdk-devel.x86_64 : OpenJDK Development Environmentjava-1.7.0-openjdk-headless.x86_64 : The OpenJDK runtime environment withoutjava-1.7.0-openjdk-javadoc.noarch : OpenJDK API Documentationjava-1.7.0-openjdk-src.x86_64 : OpenJDK Source Bundlejava-1.8.0-openjdk.i686 : OpenJDK Runtime Environmentjava-1.8.0-openjdk.x86_64 : OpenJDK Runtime Environmentjava-1.8.0-openjdk-accessibility.i686 : OpenJDK accessibility connectorjava-1.8.0-openjdk-accessibility.x86_64 : OpenJDK accessibility connectorjava-1.8.0-openjdk-accessibility-debug.i686 : OpenJDK accessibility connectorjava-1.8.0-openjdk-accessibility-debug.x86_64 : OpenJDK accessibility connectorjava-1.8.0-openjdk-debug.i686 : OpenJDK Runtime Environment with full debug onjava-1.8.0-openjdk-debug.x86_64 : OpenJDK Runtime Environment with full debug onjava-1.8.0-openjdk-demo.i686 : OpenJDK Demosjava-1.8.0-openjdk-demo.x86_64 : OpenJDK Demosjava-1.8.0-openjdk-demo-debug.i686 : OpenJDK Demos with full debug onjava-1.8.0-openjdk-demo-debug.x86_64 : OpenJDK Demos with full debug onjava-1.8.0-openjdk-devel.i686 : OpenJDK Development Environmentjava-1.8.0-openjdk-devel.x86_64 : OpenJDK Development Environmentjava-1.8.0-openjdk-devel-debug.i686 : OpenJDK Development Environment with fulljava-1.8.0-openjdk-devel-debug.x86_64 : OpenJDK Development Environment withjava-1.8.0-openjdk-headless.i686 : OpenJDK Runtime Environmentjava-1.8.0-openjdk-headless.x86_64 : OpenJDK Runtime Environmentjava-1.8.0-openjdk-headless-debug.i686 : OpenJDK Runtime Environment with fulljava-1.8.0-openjdk-headless-debug.x86_64 : OpenJDK Runtime Environment with fulljava-1.8.0-openjdk-javadoc.noarch : OpenJDK API Documentationjava-1.8.0-openjdk-javadoc-debug.noarch : OpenJDK API Documentation for packagesjava-1.8.0-openjdk-javadoc-zip.noarch : OpenJDK API Documentation compressed injava-1.8.0-openjdk-javadoc-zip-debug.noarch : OpenJDK API Documentationjava-1.8.0-openjdk-src.i686 : OpenJDK Source Bundlejava-1.8.0-openjdk-src.x86_64 : OpenJDK Source Bundlejava-1.8.0-openjdk-src-debug.i686 : OpenJDK Source Bundle for packages withjava-1.8.0-openjdk-src-debug.x86_64 : OpenJDK Source Bundle for packages withldapjdk.noarch : The Mozilla LDAP Java SDK

 

2.選擇版本後，安裝（執行以下命令會自動安裝jdk相關依賴）

[root@localhost ~]#  yum install -y java-1.8.0-openjdk已載入外掛程式：fastestmirrorLoading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirror.bit.edu.cn * updates: mirrors.aliyun.com正在解決依賴關係--> 正在檢查事務---> 軟體包 java-1.8.0-openjdk.x86_64.1.1.8.0.151-5.b12.el7_4 將被 安裝--> 正在處理依賴關係 java-1.8.0-openjdk-headless(x86-64) = 1:1.8.0.151-5.b12.el7_4，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 xorg-x11-fonts-Type1，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libpng15.so.15(PNG15_0)(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjvm.so(SUNWprivate_1.1)(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjpeg.so.62(LIBJPEG_6.2)(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjli.so(SUNWprivate_1.1)(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjava.so(SUNWprivate_1.1)(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 fontconfig(x86-64)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libpng15.so.15()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjvm.so()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjpeg.so.62()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjli.so()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libjava.so()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libgif.so.4()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libawt.so()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libXtst.so.6()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libXrender.so.1()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libXi.so.6()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libXext.so.6()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libXcomposite.so.1()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要--> 正在處理依賴關係 libX11.so.6()(64bit)，它被軟體包 1:java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64 需要

3.安裝完成，驗證是否安裝成功

[root@localhost ~]# java -versionopenjdk version "1.8.0_151"OpenJDK Runtime Environment (build 1.8.0_151-b12)OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

 

4.通過搜尋java檔案，尋找jdk預設安裝目錄

[root@localhost ~]# find / -name 'java'/etc/pki/ca-trust/extracted/java/etc/pki/java/etc/java/etc/alternatives/java/var/lib/alternatives/java/usr/bin/java/usr/lib/java/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64/jre/bin/java/usr/share/java

 

提示：通過yum命令線上安裝jdk簡單、快捷、無需配置環境變數即可使用java相關服務。
