  • 安装配置管理 之 安装和配置 JPackage Java

    修订：为 Sun Java 1.5.0 update 5 更新于 2005 年 10 月 6 日

    摘要：FC4 的发行说明中建议用户尽量避免直接使用 Sun 提供的 Java RPM，并提供了从 JPackage.org 构建 Java 的途径。本文向您介绍安装 JPackage Java 的详细步骤和注意事项。

    在 Fedora Core 4 发行说明中的 Java 软件包建议的基础上，本文将逐步向你介绍从 jpackage.org 中为 FC4 构建 Java 软件包的详细方法。

    6.1.8 Java 软件包建议

    我们不建议 Fedora Core 4 的用户使用由 Sun 提供的 Java RPM。因为它跟由 Fedora Core 4 提供的软件包所使用的名字冲突。因此，Sun Java 可能会在对系统软件包进行升级操作的过程中消失掉。建议 Fedora Core 4 的用户要不使用来自 jpackage.org 的 RPM，要不自己手动把 Sun Java tarball 压缩包安装到 /opt 里。为了系统稳定，推荐您使用 Sun Java 1.5 或以上的版本。

    当遇到未签名软件包时的解决办法

    如果你遇到某些情况类似于 Package java-1.5.0-sun-src-1.5.0.05-1jpp.i586.rpm 软件包未签名，并且使用 yum 没有安装到任何 Java 软件包，那么尝试在 /etc/yum.conf 中临时把含有 gpgcheck 的那一行注视掉。

    这很正常，因为这些软件包是在本地编译的，它们没有经过 JPackage 构建系统签名。

    [main]
    cachedir=/var/cache/yum
    debuglevel=2
    logfile=/var/log/yum.log
    pkgpolicy=newest
    distroverpkg=redhat-release
    tolerant=1
    exactarch=1
    retries=20
    obsoletes=1
    #gpgcheck=1

    # PUT YOUR REPOS HERE OR IN separate files named file.repo
    # in /etc/yum.repos.d

     

    不要忘了在安装完软件包以后把 gpgcheck 那一行去掉注释哦。

    检查 Java 版本

    [localhost i586]$ java -version
    java version "1.5.0_05"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
    Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode, sharing)
    [localhost i586]$

     

    Firefox 浏览器插件

    如果你已经安装了 java-1.5.0-sun-plugin 插件支持软件包，并且希望 firefox 使用它，你需要自己手动设置它的静态链接，因为 java-1.5.0-sun-plugin 软件包中有一个小 bug 导致它不能正确地为 FC4 firefox 软件包设置链接。

    [localhost i586]$ cd /usr/lib/firefox-1.0.7/plugins
    [localhost plugins]$ sudo ln -s /usr/lib/jvm/java-1.5.0-sun-1.5.0.05/jre/plugin/i386/ns7/libjavaplugin_oji.so .

     

    作为选择，你可以只是把静态链接放到 /usr/lib/mozilla/plugins 中，这样 mozilla 和 firefox 就都可以一起使用这个插件了，并且在浏览器升级了以后仍然有效哦。

    [localhost i586]$ cd /usr/lib/mozilla/plugins
    [localhost plugins]$ sudo rm -f libjavaplugin_oji.so
    [localhost plugins]$ sudo ln -s /usr/lib/jvm/java-1.5.0-sun-1.5.0.05/jre/plugin/i386/ns7/libjavaplugin_oji.so .

     

    仅当你以前曾经安装过别的版本的 java 才需要移除已经存在的 libjavaplugin_oji.so 的静态链接。

    切换不同的 Java 版本

    JPackage Java RPM 支持使用“alternatives”系统让你可以在不同版本的 Java 之间切换使用。

    [localhost ~]$ sudo /usr/sbin/alternatives --config java

    There are 3 programs which provide 'java'.

      Selection    Command
    -----------------------------------------------
       1           /usr/share/java/libgcj-java-placeholder.sh
       2           /usr/lib/jvm/jre-1.4.2-gcj/bin/java
    *+ 3           /usr/lib/jvm/jre-1.5.0-sun/bin/java

    Enter to keep the current selection[+], or type selection number: 2
    [localhost ~]$ java -version
    java version "1.4.2"
    gij (GNU libgcj) version 4.0.0 20050519 (Red Hat 4.0.0-8)
