如何在CentOS-7上安装java-1.8.0-openjdk和java-1.8.0-openjdk-devel

我好像在CentOS -7上试图安装openjdk-1.8.0（＆-devel），而yum无法find软件包（没有包java-1.8.0-openjdk可用）。

http://mirror.centos.org/centos/7/updates/x86_64/Packages/甚至没有从这里。

Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.tripadvisor.com * epel: s3-mirror-us-east-1.fedoraproject.org * extras: mirror.vtti.vt.edu No package java-1.8.0-openjdk available. Error: Nothing to do

CentOS的-Base.repo内：

 [base] name=CentOS-$releasever - Base mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

更具体地说，在centos-release-7-4.1708.el7.centos.x86_64上

我估计

 bash$ grep openjdk /etc/yum.conf exclude=*.i?86 *openjdk* java*

并不能相信花了很长时间在其他的一切。在排除排除之后立即开始工作。很天真！

 yum search jdk

结果：

 java-1.8.0-openjdk.x86_64 : OpenJDK Runtime Environment java-1.8.0-openjdk-devel.x86_64 : OpenJDK Development Environment

所以你可能会运行：

 yum install java-1.8.0-openjdk.x86_64 java-1.8.0-openjdk-devel.x86_64

如果这不起作用，尝试一个yum clean all并重复。

在这里输入图像说明

根据以下输出， java-1.8.0-openjdk似乎在更新中

你应该运行百胜干净所有和/或百胜支票 （将需要一些时间）解决任何问题，然后再试一次…
