centos - 无法使用 yum 或 rpm 在 Fedora 上安装 jdk

Question

帮助!我不知道如何安装 jdk!

[/usr/lib/jvm]$ su -c "yum install java-1.7.0-openjdk-devel"
Loaded plugins: langpacks, presto, refresh-packagekit
No package java-1.7.0-openjdk-devel available.
Error: Nothing to do

[/usr/lib/jvm]$ su -c "yum install java-1.7.0-openjdk"
Loaded plugins: langpacks, presto, refresh-packagekit
No package java-1.7.0-openjdk available.
Error: Nothing to do

[/usr/lib/jvm]$ su -c "yum install java-1.6.0-openjdk-devel"
Loaded plugins: langpacks, presto, refresh-packagekit
No package java-1.6.0-openjdk-devel available.
Error: Nothing to do

[/usr/lib/jvm]$ su -c "yum install java-1.6.0-openjdk"
Loaded plugins: langpacks, presto, refresh-packagekit
No package java-1.6.0-openjdk available.
Error: Nothing to do

这里我手动下载了一些 rpm，最后一个是从 oracle 的网站上下载的:

[~]$ rpm -ivh java-1.7.0-openjdk-devel-1.7.0.19-2.3.9.3.fc20.x86_64.rpm 
error: Failed dependencies:

调试

这里是一些调试信息:

[/usr/lib/jvm]$ yum search jdk
Loaded plugins: langpacks, presto, refresh-packagekit
=========================================================== N/S Matched: jdk ============================================================
java-1.7.0-openjdk-javadoc.noarch : OpenJDK API Documentation
jdk.x86_64 : Java(TM) Platform Standard Edition Development Kit
ldapjdk.noarch : The Mozilla LDAP Java SDK
Name and summary matches only, use "search all" for everything.

.

[/usr/lib/jvm]$ yum list java*
Loaded plugins: langpacks, presto, refresh-packagekit
Installed Packages
java-1.5.0-gcj.x86_64   

.

[/usr/lib/jvm]$ cat /etc/fedora-release 
Fedora release 18 (Spherical Cow)

要求

我必须有“jni.h”、“libjava.so”、“libhpi.so” ”、“lipverify.so”和“libjvm.so”。

到目前为止，我发现这些没有我需要的:

• 不需要的版本(当然):
  • jdk1.7.0_06 <-- 我对这个感到惊讶，但它没有 libjvm 和 libhpi
  • java-1.7.0
  • java-openjdk
  • java-1.7.0-openjdk-1.7.0.9.x86_64
  • java-1.5.0-gcj-4.4
  • java-1.6.0-openjdk
  • java-1.7.0-openjdk.x86_64
  • jre-1.5.0-gcj
  • jre-1.7.0-openjdk.x86_64
  • jre-openjdk
  • jre-1.7.0
  • jre-7u11-linux-x64.rpm java-1.5.0-gcj-1.5.0.0
  • jre-1.5.0
  • jre1.7.0_11
  • jre-gcj

这些是:

• 所需的版本(据我所知，可能还有更多):
  • jdk1.6.0_34-x86
  • jdk1.5.0_22-x86
  • java-6-openjdk

有人可以帮我安装 jdk1.6 或 java-6-openjdk 吗？

Answer 1

这里的问题是，当您已经拥有 Oracle JDK 6 时，您无法使用 Oracle rpm 安装 JDK 7，因为它会尝试安装 /etc/init.d/jexec 脚本，该脚本是已经安装并需要 JDK 6。

如果您要使用 Oracle 发行版，我建议您坚持使用 tarball 或自解压 *.bin 并使用 JAVA_HOME，因为它没有这个问题，而且您可能不需要 jexec .
